It will also compare the screening features of the CUDIT-R with those of the DSM-5 criteria for cannabis use disorder (CUD) based on the SCID-5-CT in a group of university students in Tehran, Iran. The study used the stratified random sampling technique to collect data from 541 students (19 to 24 years old) who used cannabis in Tehran universities in 2024. Confirmatory factor analysis confirmed the uni-dimensionality of the CUDIT-R-Pr. We checked the reliability of the CUDIT-R-Pr using Cronbach Alpha, split-half, inter-rater, test-retest stability over time, and parallel testing equivalence. The results indicated that CUDIT-R-Pr is reliable, reproducible, and responsive, with substantial agreement and adequate interpretability. The CUDIT-R shows that it can tell the difference between different levels of cannabis use severity, which is known as discriminant validity. Receiver operating characteristic analyses confirmed this, using an area under the receiver operating characteristics curve (AUC = 0.95) at a cutoff of ten or less. This allowed CUDIT-R-Pr to accurately predict any DSM-5 based on the highest correctly classified value (0.89), demonstrating high levels of sensitivity (0.96), specificity (0.69), and Youden value (0.65). The exact maximum Youden index (0.72) showed that CUDIT-R-Pr could also predict moderate DSM-5 with a cutoff of twelve or less. To validate and generalize the CUDIT-R-Pr for use among Iranian cannabis users, we need more research.展开更多

It has been validated in both the general population in Mexico and other Latin American countries. This study aims to further consolidate the validity of the BIOS-G in a specific population. The objectives are to assess the psychometric properties of its items, validate its unidimensional structure, describe its distribution, verify its internal consistency, and examine its direct relationship with affective balance and positive affect, as well as its inverse relationship with emotional exhaustion and negative affect among Mexican university teachers. The BIOS-G, the CESQT emotional exhaustion subscale, and Scale of Positive and Negative Experience (SPANE) were administered to a non-probability sample of 213 Mexican university teachers. All items demonstrated discriminative power and internal consistency. The scale showed internal consistency (Green-Yang ordinal ω = 0.74 and McDonald ordinal ω = 0.88). The one-factor model presented good to acceptable fit to the data, with an average variance extracted of 0.65. Its distribution was negatively skewed and mesokurtic. The BIOS-G correlated directly with SPANE’s affective balance and positive emotional experiences and inversely with negative emotional experiences and emotional exhaustion, with moderate strengths of association. Its mean score was higher in men than in women and correlated positively with age. It is concluded that the BIOS-G demonstrates internal consistency and validity evidence among Mexican university teachers, and its use in this specific population is recommended.展开更多

We enrolled adult consenting patients with bilateral chronic eye diseases who presented to 14 hospitals across Egypt from October to December 2012, and documented their clinical findings. Psychometric properties were then tested using STATA.RESULTS:We recruited 379 patients, whose mean age was(54.5±15)y. Of 46.2% were males, 227 had cataract,31 had glaucoma, 23 had retinal detachment, 37 had diabetic retinopathy, and 61 had miscellaneous visual defects. Non-response rate and the floor and ceiling numbers of the Arabic version(ARB-VFQ-25) were calculated. Internal consistency was high in all subscales(except general health), with Cronbach-α ranging from0.702-0.911. Test-retest reliability was high(intraclass correlation coefficient 0.79).CONCLUSION:RB-VFQ-25 isareliableandvalidtool for assessing visual functions of Arabic speaking patients. However, some questions had high non-response rates and should be substituted by available alternatives. Our results support the importance of including self-reported visual functions as part of routine ophthalmologic examination.展开更多

Design: Cross-sectional study design and scale development. Settings: Totally, 469 adults (response rate 63.5%) with Type 1 diabetes completed the questionnaires. Participants were recruited from two university hospitals in Sweden. Participants: Eligible patients were those who met the following inclusion criteria: diagnosed with Type 1 diabetes, diabetes duration of at least 1 year and aged at least 18 years. Methods: The Fear of Complications Questionnaire was translated using the forward-backward translation method. Factor analyses of the questionnaire were performed in two steps using both exploratory and confirmatory factor analysis. Convergent validity was examined using the Hospital Anxiety and Depression Scale and the Fear of Hypoglycaemia Fear Survey. Internal consistency was estimated using Cronbach’s alpha. Results: Exploratory factor analysis supported a two-factor solution. One factor contained three items having to do with fear of kidney-related complications and one factor included the rest of items concerning fear of other diabetes-related complications, as well as fear of complications in general. Internal consistency was high Cronbach’s alpha 0.96. The findings also gave support for convergent validity, with significant positive correlations between measures (r = 0.51 to 0.54). Conclusion: The clinical relevance of the identified two-factor model with a structure of one dominant subdomain may be considered. We suggest, however a one-factor model covering all the items as a relevant basis to assess fear of complications among people with Type 1 diabetes.展开更多

Initially, forward-backward translation was used to translate the English version of OSDI into Arabic. The translated questionnaire was tested for equivalence and cultural adaptability. Totally 200 subjects were then recruited from a non-clinical population and asked to complete the Arabic version of the OSDI(ARB-OSDI). The reliability of the questionnaire was assessed using Cronbach’s-α. A subgroup of 30 participants was asked to complete the questionnaire on two occasions to test the test-retest reliability.RESULTS: A total of 200 participants were enrolled in the study. The average age of the study participants was 31.21±13.2 y and 57% were male. An acceptable internal consistency level for the ARB-OSDI questionnaire measured by Cronbach’s-α was revealed. All questions showed good internal consistency. Test-retest reliability analysis revealed good stability(interclass correlation coefficient, r=0.832, P<0.001). The construct validity for the questionnaire was also high.CONCLUSION: The ARB-OSDI questionnaire shows very good psychometric properties(acceptable internal consistency and test-retest reliability). That makes the questionnaire a valid potential tool to use in Arabic-speaking countries to monitor symptoms of dry eye disease in a larger population.展开更多

This paper aims to examine the psychometric properties of the Maslach Burnout Questionnaire (MBI-HSS) for validation of use in Lebanon, and to describe burnout and associated factors amongst nurses in Lebanon especially the gender and employment sector. Methods: The psychometric properties of the Arabic version of MBI-HSS were studied amongst a sample of 200 nurses. In this descriptive study, survey data were collected from private and public hospitals. The data were analyzed by means of descriptive statistics and multivariate analysis. Results: The results indicated satisfactory reliability through internal consistency for all three scales of the MBI-HSS. The factor analysis was quite satisfactory. Most of staff had scores which indicated they were burnt out. Nearly three quarters (77.5%) reported emotional exhaustion, 36.0% reported depersonalization while almost one third (33.0%) experienced reduced personal accomplishment. Burnout increases for 30-39 years age groups. Married nurses had significantly higher emotional exhaustion. Depersonalization was highest among nurses in private sector, and personal accomplishment was highest among nurses in public sector. Depersonalization proved to be higher in night and rotating shift nurses. Depression, backache, and headache were predictors of burnout. Conclusion: Findings indicate that the main psychometric properties of reliability and validity of the Arabic version of MBI-HSS appear to be satisfactory. Burnout is particularly prominent and severe in the nurses working population. The implications of these findings for interventions that reduce burnout and promote nursing mental health are therefore in the interest of employers, governments and policy makers.展开更多

Patients and Methods: This was a cross-sectional study over a period of six months, in patients with symptomatic knee osteoarthritis. All patients met the clinical and radiological criteria of the ACR. The OAKHQOL questionnaire was used to investigate the quality of life of patients. Results: One hundred and six patients were included. There were 94 (88.7%) women and 12 (11.3%) men with a sex ratio of 0.12. The average age of patients was 55 ± 10.4 years. The average pain intensity was 55.1 ± 22.4. The majority of patients (69.8%) had stage 3 of Kellgren and Lawrence classification. The dimension “pain” had the lowest normalized score (60.6). There was a significant correlation between the age range of 30 to 40 years and declining mental health (49.5) . The patients with over 60 years of age had a decrease in pain tolerance and reduced social activities. Lequesne score was associated with severe all dimensions except “social support” of the patient. Conclusion: The knee has an impact on quality of life of patients followed in rheumatology by OAKHQOL questionnaire.展开更多

The aim of the present study was to investigate the construct validity and internal consistency of the Brunel Mood Scale (BRUMS) for use with different populations, which are physically active and apparently healthy. Measures were obtained from 1295 male (N = 709, 34 ± 20 years, mean ± SD) and female (N = 576, 43 ± 24 years, mean ± SD) volunteers. Factor analysis was used, verifying that six factors (components) accounted for 62.65% of the total variance of the scale. The Varimax method with Kaiser Normalization for the rotation of the factors for the main components, and it was observed that the 24 scale items loaded on six mood factors (anger, depression, tension, vigor, fatigue, and confusion). Internal consistency was good for all the factors identified. We suggest that the results provide some support for validity of the BRUMS for use with different populations, which are physically active and apparently healthy.展开更多

One advocated approach to test unidimensionality within the Rasch model is to identify two item sets from a Principal Component Analysis (PCA) of residuals, estimate separate person measures based on the two item sets, compare the two estimates on a person-by-person basis using t-tests and determine the number of cases that differ significantly at the 0.05-level;if ≤5% of tests are significant, or the lower bound of a binomial 95% confidence interval (CI) of the observed proportion overlaps 5%, then it is suggested that strict unidimensionality can be inferred;otherwise the scale is multidimensional. Given its proposed significance and potential implications, this procedure needs detailed scrutiny. This paper explores the impact of sample size and method of estimating the 95% binomial CI upon conclusions according to recommended conventions. Normal approximation, “exact”, Wilson, Agresti-Coull, and Jeffreys binomial CIs were calculated for observed proportions of 0.06, 0.08 and 0.10 and sample sizes from n= 100 to n= 2500. Lower 95%CI boundaries were inspected regarding coverage of the 5% threshold. Results showed that all binomial 95% CIs included as well as excluded 5% as an effect of sample size for all three investigated proportions, except for the Wilson, Agresti-Coull, and JeffreysCIs, which did not include 5% for any sample size with a 10% observed proportion. The normal approximation CI was most sensitive to sample size. These data illustrate that the PCA/t-test protocol should be used and interpreted as any hypothesis testing procedure and is dependent on sample size as well as binomial CI estimation procedure. The PCA/t-test protocol should not be viewed as a “definite” test of unidimensionality and does not replace an integrated quantitative/qualitative interpretation based on an explicit variable definition in view of the perspective, context and purpose of measurement.展开更多
文摘Loneliness is a complex and usually unpleasant emotional response to isolation,which has been considered the latest global health epidemic exacerbated by the coronavirus disease 2019 pandemic,affecting nearly twothirds of older adults.Some profound health implications carried by loneliness include depression,cognitive impairment,hypertension and frailty.Across the world,there is no consensus definition of loneliness,and its measure is based on the phenomenological perspective of the individual.The 20-item University of California Los Angeles Loneliness Scale version 3(UCLA-20)is the most common measure.This scale demonstrates acceptable psychometric properties but is too long and complex for a phone interview.This paper addresses the increasing need to shorten this scale by adopting classical item response theory and network psychometrics to advance scale development.Through an item reduction analysis,we trimmed the original scale into an effective short form,which is as valid as the original one.With respondents’time at a premium in most research nowadays,this shortform scale is an efficient and practical alternative to the original UCLA-20.

文摘Background:The recently developed Depression,Anxiety,and Stress Scales–Youth Version(DASS-Y)shows promise as a tool for assessing youth mental health,but its consistency across timepoints and diverse ages remains underexplored.The present study evaluated whether the DASS-Y reliably measured depression,anxiety,and stress among school-aged youth(aged 9–18 years)across distinct time periods and educational stages.Methods:Two studies were conducted.Study 1 examined consistency over three months using data from 736 Central Chinese high school students who completed surveys at both timepoints.Study 2 tested consistency across educational levels among 2321 primary and 1676 middle school students.Traditional confirmatory factor analysis(CFA),exploratory structural equation modeling(ESEM),and Rasch analysis were employed to assess the scale’s construct validity and measurement invariance.Results:Rasch analysis indicated acceptable DASS-Y item fit(infit/outfit statistics=0.50–1.50)and moderate test-retest reliability(ICCs=0.64–0.69).The ESEM approach demonstrated superior model fit compared to CFA,achieving a good RMSEA(0.056–0.062)and lower latent factor correlations(r=0.40–0.60),supporting longitudinal scalar invariance.Across educational levels,measurement invariance was supported,with only a small number of items exhibiting differential item functioning(DIF).Conclusion:The present study demonstrates that the DASS-Y is a reliable tool for assessing emotional health among non-clinical school-aged youth,offering educators a validated measure to monitor psychological well-being across developmental stages and time,thereby informing strategies to support youth mental health in community and educational settings.Future research among clinical populations is needed to extend its utility for diagnostic purposes.

文摘Objective:The purpose of this study was to develop and psychometrically analyze the characteristics of the good nurse from the perspective of service recipients.Methods:The current research was conducted namely in 2 qualitative and psychometric phases.In the first stage,the items of the questionnaire were designed by interviews with nursing service recipients,and in the next stage,construct validity,content validity,face validity,reliability,and internal consistency were all reviewed.Results:Based on the results of the content analysis of the interview with nursing service recipients and related literature review,an 80-item questionnaire was designed.After analyzing its content validity,40 items were validated and 40 were eliminated,which were prepared by using exploratory factor analysis,6 factors of attentive and communicative,patron and companionable,complete caregiver,safer and skillful,advocate and confidant.The reliability of the tool was assessed by applying Cronbach’s alpha method of 0.90.Conclusions:“The good nurse characteristics tool”could be used to assess the service receivers’point of view and provide useful information regarding nurses’performance to managers and nurses and will provide the basis for improving the quality of nursing services.
文摘The purpose of this paper is to look into how reliable and valid the Persian version of the Cannabis Use Disorder Identification Test-Revised (CUDIT-R-Pr) is. It will also compare the screening features of the CUDIT-R with those of the DSM-5 criteria for cannabis use disorder (CUD) based on the SCID-5-CT in a group of university students in Tehran, Iran. The study used the stratified random sampling technique to collect data from 541 students (19 to 24 years old) who used cannabis in Tehran universities in 2024. Confirmatory factor analysis confirmed the uni-dimensionality of the CUDIT-R-Pr. We checked the reliability of the CUDIT-R-Pr using Cronbach Alpha, split-half, inter-rater, test-retest stability over time, and parallel testing equivalence. The results indicated that CUDIT-R-Pr is reliable, reproducible, and responsive, with substantial agreement and adequate interpretability. The CUDIT-R shows that it can tell the difference between different levels of cannabis use severity, which is known as discriminant validity. Receiver operating characteristic analyses confirmed this, using an area under the receiver operating characteristics curve (AUC = 0.95) at a cutoff of ten or less. This allowed CUDIT-R-Pr to accurately predict any DSM-5 based on the highest correctly classified value (0.89), demonstrating high levels of sensitivity (0.96), specificity (0.69), and Youden value (0.65). The exact maximum Youden index (0.72) showed that CUDIT-R-Pr could also predict moderate DSM-5 with a cutoff of twelve or less. To validate and generalize the CUDIT-R-Pr for use among Iranian cannabis users, we need more research.

文摘Background:Weight stigma is prevalent and has multiple sources,which have significant effects on individual,social,physical,and psychological health.This study evaluated the psychometric properties of the Thai version of WeSEI to provide a valid tool to assess weight stigma in Thai young adults.Methods:A cross-sectional online survey recruited 517 Thai university students from October 2024 to May 2025.All participants completed demographic information and standardized self-reported instruments,including WeSEI,Depression,Anxiety,and Stress scale 21(DASS-21),Weight Self-Stigma Questionnaire(WSSQ),and Perceived Weight Stigma Scale(PWSS).The psychometric properties of the Thai version of WeSEI were examined via confirmatory factor analysis(CFA)with some validity indices.Results:The 7-factor structure of the Thai version of the WeSEI was supported across sex and weight status subgroups,indicating good construct validity.In addition,internal consistency(Cronbach’sα=0.972;McDonald’sω=0.972),convergent,and discriminant validity also indicated that the Thai version of the WeSEI had good psychometric properties and assessed weight stigma among young people in Thailand.Conclusions:Sound psychometric properties of the Thai adaptation of WeSEI allows the identification of various sources contributing to weight stigma and to identify those experiencing high levels of weight stigma.It also provides evidence to support targeted interventions to reduce weight stigma and its associated mental health impacts in further research.Further studies are necessary to explore the utilization of WeSEI for weight stigma in Thailand.
文摘The Brief Interactive Optimism Scale (BIOS-G), recently published, was developed to measure optimism based on the interactive personality styles theory in the general population of Mexican adults. It has been validated in both the general population in Mexico and other Latin American countries. This study aims to further consolidate the validity of the BIOS-G in a specific population. The objectives are to assess the psychometric properties of its items, validate its unidimensional structure, describe its distribution, verify its internal consistency, and examine its direct relationship with affective balance and positive affect, as well as its inverse relationship with emotional exhaustion and negative affect among Mexican university teachers. The BIOS-G, the CESQT emotional exhaustion subscale, and Scale of Positive and Negative Experience (SPANE) were administered to a non-probability sample of 213 Mexican university teachers. All items demonstrated discriminative power and internal consistency. The scale showed internal consistency (Green-Yang ordinal ω = 0.74 and McDonald ordinal ω = 0.88). The one-factor model presented good to acceptable fit to the data, with an average variance extracted of 0.65. Its distribution was negatively skewed and mesokurtic. The BIOS-G correlated directly with SPANE’s affective balance and positive emotional experiences and inversely with negative emotional experiences and emotional exhaustion, with moderate strengths of association. Its mean score was higher in men than in women and correlated positively with age. It is concluded that the BIOS-G demonstrates internal consistency and validity evidence among Mexican university teachers, and its use in this specific population is recommended.
文摘Objectives:Problematic use of the internet(PUI)has been increasingly associated with various mental health issues,highlighting the need for accurate assessment tools.The Assessment of Criteria for Specific Internet-use Disorder(ACSID-11)is a validated psychometric instrument designed to measure distinct forms of PUI across multiple online activities.However,its applicability and validity have not yet been established within the Indonesian context.Therefore,this study aimed to translate and validate the ACSID-11 for use among Indonesian populations.Methods:The translation procedure of the ACSID-11 involved forward translation,back translation,and expert panel discussions.This research involved 600 undergraduate and post-graduate students from universities in Indonesia(mean[SD]age=21.60[2.74]years;409[68%]females).Cronbach’s Alpha(α)and McDonald’s Omega(ω)were used to measure the internal consistency of the ACSID-11.Confirmatory factor analysis(CFA)was used in testing the construct validity of the ACSID-11.Results:The ACSID-11 demonstrated validity and reliability in assessing different types of PUI in the present Indonesian sample(α=0.67–0.96;ω=0.68–0.96).The CFA results supported a four-factor structure for the Indonesian version of the ACSID-11.Conclusion:The findings suggest that the Indonesian version of the ACSID-11 is a valid and reliable tool for assessing specific forms of PUI among Indonesian students.Future research and clinical applications are encouraged to utilize the ACSID-11 for early identification,intervention,and prevention strategies targeting PUI within this population.
文摘AIM:To develop and test an Arabic version of the National Eye Institute Visual Function Questionnaire-25(NEI-VFQ-25).METHODS:NEI-VFQ-25 was translated into Arabic according to WHO translation guidelines. We enrolled adult consenting patients with bilateral chronic eye diseases who presented to 14 hospitals across Egypt from October to December 2012, and documented their clinical findings. Psychometric properties were then tested using STATA.RESULTS:We recruited 379 patients, whose mean age was(54.5±15)y. Of 46.2% were males, 227 had cataract,31 had glaucoma, 23 had retinal detachment, 37 had diabetic retinopathy, and 61 had miscellaneous visual defects. Non-response rate and the floor and ceiling numbers of the Arabic version(ARB-VFQ-25) were calculated. Internal consistency was high in all subscales(except general health), with Cronbach-α ranging from0.702-0.911. Test-retest reliability was high(intraclass correlation coefficient 0.79).CONCLUSION:RB-VFQ-25 isareliableandvalidtool for assessing visual functions of Arabic speaking patients. However, some questions had high non-response rates and should be substituted by available alternatives. Our results support the importance of including self-reported visual functions as part of routine ophthalmologic examination.
文摘Objective:Assessing diabetes self care management is essential for nursing care for diabetes.There is a need to have valid and reliable scales that assess the actual performance of diabetes self management,The purpose of this study was to revise and conduct psychometric testing and analysis of the Diabetes Self Management Scale(DSMS).Methods:A cross-sectional methodological design was used.A convenience sample was used and 78 adults with diabetes and taking insulin from five sites in the Midwest area of the U.S participated in the study.Reliability analysis was done using Ferketich techniques to make decisions about whether any given item should be retained or deleted.Results:A descriptive analysis for the 60 items of the scale was conducted;several items had low variability compared to the other items on the scale.The correlation matrices showed that a total of 20 items had poor item characteristics.These 20 items were deleted resulting in developing 40-item version of the scale.The 40-item scale had high level of internal consistency(Cronbach'sα=0.947).The validity testing of the 40-item scale was guided by the Research Model for Diabetes Self Care Management;results were congruent with the model and showed strong correlation with self efficacy,moderate correlation with self care agency,and weak correlation with diabetes knowledge.Conclusion:The items and the scale(DSMS)have undergone careful psychometric testing.The 40-item DSMS is a reliable and valid instrument to measure diabetes self care management among people with diabetes.

文摘Objectives The aim of this study was to analyze the psychometric properties(reliability and validity)of the Social Isolation Scale(SIS)in a sample of Portuguese community-dwelling older adults.Methods A transversal descriptive study was carried out with a convenience sample of 250 community-dwelling older adults(≥65 years).The survey comprised a sociodemographic questionnaire,SIS,Geriatric Depression Scale-4(GDS-4),6-item Lubben Social Network Scale(LSNS-6),a loneliness self-assessment question,and Satisfaction with Life Scale(SWLS).Construct validity(confirmatory factor analysis)and convergent validity were analyzed,and ISI internal reliability(composite reliability),external reliability(test-retest,intraclass correlation coefficient)and inter-rater reliability(Cohen’s kappa coefficient)were evaluated.Results Confirmatory factor analysis showed a two-factor model with an excellent index of fit.The SIS showed significant correlations with LSNS-6(rs=0.47),SWLS(rs=0.26),the loneliness self-assessment question(rs=0.35),and GDS-4(rs=−0.16).SIS composite reliability was good(0.708).The inter-class correlation coefficient varied from 0.84 to 0.98.The Cohen’s kappa coefficient ranged from 0.936 to 1.Conclusions SIS has been shown to be a valid and reliable instrument for assessing social isolation among Portuguese community-dwelling older adults.Healthcare professionals,particularly nurses working in community settings,can use SIS to assess social isolation in older adults to design,implement,and evaluate interventions.
文摘Objectives: To translate and evaluate the psychometric properties of the Swedish version of the Fear of Complications Questionnaire. Design: Cross-sectional study design and scale development. Settings: Totally, 469 adults (response rate 63.5%) with Type 1 diabetes completed the questionnaires. Participants were recruited from two university hospitals in Sweden. Participants: Eligible patients were those who met the following inclusion criteria: diagnosed with Type 1 diabetes, diabetes duration of at least 1 year and aged at least 18 years. Methods: The Fear of Complications Questionnaire was translated using the forward-backward translation method. Factor analyses of the questionnaire were performed in two steps using both exploratory and confirmatory factor analysis. Convergent validity was examined using the Hospital Anxiety and Depression Scale and the Fear of Hypoglycaemia Fear Survey. Internal consistency was estimated using Cronbach’s alpha. Results: Exploratory factor analysis supported a two-factor solution. One factor contained three items having to do with fear of kidney-related complications and one factor included the rest of items concerning fear of other diabetes-related complications, as well as fear of complications in general. Internal consistency was high Cronbach’s alpha 0.96. The findings also gave support for convergent validity, with significant positive correlations between measures (r = 0.51 to 0.54). Conclusion: The clinical relevance of the identified two-factor model with a structure of one dominant subdomain may be considered. We suggest, however a one-factor model covering all the items as a relevant basis to assess fear of complications among people with Type 1 diabetes.

文摘AIM: To develop an Arabic version of the ocular surface disease index(OSDI) and to assess its reliability and validity.METHODS: A cross sectional study was carried out to validate the Arabic version of the OSDI questionnaire. Initially, forward-backward translation was used to translate the English version of OSDI into Arabic. The translated questionnaire was tested for equivalence and cultural adaptability. Totally 200 subjects were then recruited from a non-clinical population and asked to complete the Arabic version of the OSDI(ARB-OSDI). The reliability of the questionnaire was assessed using Cronbach’s-α. A subgroup of 30 participants was asked to complete the questionnaire on two occasions to test the test-retest reliability.RESULTS: A total of 200 participants were enrolled in the study. The average age of the study participants was 31.21±13.2 y and 57% were male. An acceptable internal consistency level for the ARB-OSDI questionnaire measured by Cronbach’s-α was revealed. All questions showed good internal consistency. Test-retest reliability analysis revealed good stability(interclass correlation coefficient, r=0.832, P<0.001). The construct validity for the questionnaire was also high.CONCLUSION: The ARB-OSDI questionnaire shows very good psychometric properties(acceptable internal consistency and test-retest reliability). That makes the questionnaire a valid potential tool to use in Arabic-speaking countries to monitor symptoms of dry eye disease in a larger population.
文摘Background: Burnout is a mental condition defined as a result of continuous and long-term stress exposure, particularly related to psychosocial factors at work. This paper aims to examine the psychometric properties of the Maslach Burnout Questionnaire (MBI-HSS) for validation of use in Lebanon, and to describe burnout and associated factors amongst nurses in Lebanon especially the gender and employment sector. Methods: The psychometric properties of the Arabic version of MBI-HSS were studied amongst a sample of 200 nurses. In this descriptive study, survey data were collected from private and public hospitals. The data were analyzed by means of descriptive statistics and multivariate analysis. Results: The results indicated satisfactory reliability through internal consistency for all three scales of the MBI-HSS. The factor analysis was quite satisfactory. Most of staff had scores which indicated they were burnt out. Nearly three quarters (77.5%) reported emotional exhaustion, 36.0% reported depersonalization while almost one third (33.0%) experienced reduced personal accomplishment. Burnout increases for 30-39 years age groups. Married nurses had significantly higher emotional exhaustion. Depersonalization was highest among nurses in private sector, and personal accomplishment was highest among nurses in public sector. Depersonalization proved to be higher in night and rotating shift nurses. Depression, backache, and headache were predictors of burnout. Conclusion: Findings indicate that the main psychometric properties of reliability and validity of the Arabic version of MBI-HSS appear to be satisfactory. Burnout is particularly prominent and severe in the nurses working population. The implications of these findings for interventions that reduce burnout and promote nursing mental health are therefore in the interest of employers, governments and policy makers.
文摘Objectives:This study aimed to translate the revised 17-item Diabetes Distress Scale(DDS17,2017)into mandarin(simplified)Chinese and validate the Chinese version of DDS17(C-DDS17,2021)among adult patients with type 2 diabetes in China.Methods:A scale translation and cross-sectional validation study was conducted.The DDS17 was translated into mandarin(simplified)Chinese through a five-step process:authorization,forward translation,synthesis,back translation,and amendment.During this session,59 patients assessed the understandability and readability of the translated scale.From June 7 to September 4,2021,a cross-sectional study that adhered to the COSMIN checklist was conducted with 400 individuals with type 2 diabetes from three Class A tertiary comprehensive hospitals in Beijing,China.The content,construct,convergent,discriminant validity,and reliability(Cronbach’s a coefficient and item-total correlation coefficients)of the C-DDS17 were evaluated.This study was a part of a project registered in the Chinese Clinical Trial Registry(no.ChiCTR2100047071).Results:Among the participants,33.3%(133/400)of them experienced moderate to high diabetes distress.The content validity indices of the C-DDS17 equaled 1.00.The scale yielded a four-factor structure.The average variances extracted were 0.42e0.57,which was lower than squared correla-tions.Cronbach’s a coefficient was 0.88 for the overall scale and ranged from 0.76 to 0.81 for sub-scales.Corrected item-total correlation coefficients ranged from 0.42 to 0.61.The eighth item(“Feeling that I am often failing with my diabetes routine”)was better fit to physician distress than regimen distress but had little influence on the validation results.Conclusions:The C-DDS17 is a reliable and valid instrument for assessing diabetes distress in patients with type 2 diabetes.It is a promising instrument for early identification and management of diabetes distress in clinical practice and trials.
文摘Objective:This study aimed to examine the psychometric properties of the Conditions for Workplace Effectiveness Questionnaire-Ⅱ-Arabic Version(CWEQ-Ⅱ-AV),which measures structural empowerment among nurses.To enhance the usability and credibility of the CWEQ-Ⅱ among researchers within Arabicspeaking countries,a valid and reliable Arabic version of the measure is necessary.Methods:A cross-sectional research design was used.From December 2018 to June 2019,275 nurses working in 4 hospitals participated in the study.Reliability was assessed by examining internal consistency and split-half reliability.A confirmatory factor analysis was performed to evaluate the factor structure of the CWEQ-Ⅱ-AV.Results:The psychometric properties of the CWEQ-Ⅱ-AV were excellent regarding the six-factor model(opportunity,information,resources,support,formal power,and informal power).The results showed the following fit indices meet the criteria set a priori:comparative fit index(CFI)=0.96,root mean square of error approximation(RMSEA)=0.06,andХ^(2)/df=2.08.Cronbach's a coefficient was 0.95 for the total questionnaire and ranged between 0.83 and 0.89 for the individual subscales.The split-half reliability was 0.91 for the total questionnaire and ranged from 0.83 to 0.87 for individual subscales.Conclusion:This study provides evidence that CWEQ-Ⅱ-AV is both a reliable and valid measure of structural empowerment among Arab nurses.
文摘Objective: To study the quality of life of patients with knee OA with the questionnaire OAKHQOL (OsteoArthritis of Knee Hip Quality Of Life). Patients and Methods: This was a cross-sectional study over a period of six months, in patients with symptomatic knee osteoarthritis. All patients met the clinical and radiological criteria of the ACR. The OAKHQOL questionnaire was used to investigate the quality of life of patients. Results: One hundred and six patients were included. There were 94 (88.7%) women and 12 (11.3%) men with a sex ratio of 0.12. The average age of patients was 55 ± 10.4 years. The average pain intensity was 55.1 ± 22.4. The majority of patients (69.8%) had stage 3 of Kellgren and Lawrence classification. The dimension “pain” had the lowest normalized score (60.6). There was a significant correlation between the age range of 30 to 40 years and declining mental health (49.5) . The patients with over 60 years of age had a decrease in pain tolerance and reduced social activities. Lequesne score was associated with severe all dimensions except “social support” of the patient. Conclusion: The knee has an impact on quality of life of patients followed in rheumatology by OAKHQOL questionnaire.
文摘Despite depression being a global mental health disorder,many people with depression do not seek psychiatric help.In particular,it has been reported that only 15.7%of medical students seek treatment.A longer duration of untreated illness(DUI)leads to clinically poor results.To shorten the DUI,the mental health literacy(MHL)with regard to depression needs to be improved,although it is unclear which MHL components will improve the help-seeking process.Additionally,the existing MHL scale for depression is poorly validated for structural validity.Therefore,the purpose of this study was to develop an MHL scale for depression with verified reliability and validity(particularly structural validity)and verify its relationship with the help-seeking process.For this purpose,we adapted the mixed research method.First,we conducted a systematic literature review on MHL scales for depression to prepare a draft scale with content validity.Second,we conducted semi-structured interviews on MHL with outpatients with depression.Consequently,78 questions on MHL for depression were extracted.Third,to develop our scale,we verified the reliability and validity of these questions with 782 health professional students.The sample size was 780 and data collection was performed by collective survey method.It was conducted in 2018 in Japan.To verify the factor structure,exploratory and confirmatory factor analyses were conducted.We also examined the internal consistency,test-retest reliability,and criterion-related validity.The exploratory factor analysis revealed a three-factor structure(recognition of depression symptoms,helpseeking preferences,and depression onset possibility)with 10 items.According to the confirmatory factor analysis results,the goodness of fit indicators had a good fit.The internal consistency,test-retest reliability,and criterion-related validity had good values.Fourth,the relationship between the MHL of depression and other factors affecting the help-seeking process was examined using structural equation modelling.The same sample size(as above)was applied.All three components of the MHL of depression influenced‘recognition of depression’.In particular,depression onset possibility had the greatest impact on the help-seeking process.Whereas,the MHL of depression had little or no influence on‘intention of consultation’and‘psychiatric consultation’(second and third steps of help-seeking).The largest influence on psychiatric consultation was the recommendation of consultation from others.The multiple correlation coefficients were the recognition of depression,R2=0.33;intention of consultation,R2=0.43;and psychiatric consultation,R2=0.36;and the model was a good fit.This study identified the specific components of the depression MHL that influence the help-seeking process.Subsequently,it is necessary to provide specific MHL education to health professional students,their families,university staff,and teachers.
文摘There is a positive relationship between mood states and mental health. The aim of the present study was to investigate the construct validity and internal consistency of the Brunel Mood Scale (BRUMS) for use with different populations, which are physically active and apparently healthy. Measures were obtained from 1295 male (N = 709, 34 ± 20 years, mean ± SD) and female (N = 576, 43 ± 24 years, mean ± SD) volunteers. Factor analysis was used, verifying that six factors (components) accounted for 62.65% of the total variance of the scale. The Varimax method with Kaiser Normalization for the rotation of the factors for the main components, and it was observed that the 24 scale items loaded on six mood factors (anger, depression, tension, vigor, fatigue, and confusion). Internal consistency was good for all the factors identified. We suggest that the results provide some support for validity of the BRUMS for use with different populations, which are physically active and apparently healthy.
文摘Psychometric theory requires unidimensionality (i.e., scale items should represent a common latent variable). One advocated approach to test unidimensionality within the Rasch model is to identify two item sets from a Principal Component Analysis (PCA) of residuals, estimate separate person measures based on the two item sets, compare the two estimates on a person-by-person basis using t-tests and determine the number of cases that differ significantly at the 0.05-level;if ≤5% of tests are significant, or the lower bound of a binomial 95% confidence interval (CI) of the observed proportion overlaps 5%, then it is suggested that strict unidimensionality can be inferred;otherwise the scale is multidimensional. Given its proposed significance and potential implications, this procedure needs detailed scrutiny. This paper explores the impact of sample size and method of estimating the 95% binomial CI upon conclusions according to recommended conventions. Normal approximation, “exact”, Wilson, Agresti-Coull, and Jeffreys binomial CIs were calculated for observed proportions of 0.06, 0.08 and 0.10 and sample sizes from n= 100 to n= 2500. Lower 95%CI boundaries were inspected regarding coverage of the 5% threshold. Results showed that all binomial 95% CIs included as well as excluded 5% as an effect of sample size for all three investigated proportions, except for the Wilson, Agresti-Coull, and JeffreysCIs, which did not include 5% for any sample size with a 10% observed proportion. The normal approximation CI was most sensitive to sample size. These data illustrate that the PCA/t-test protocol should be used and interpreted as any hypothesis testing procedure and is dependent on sample size as well as binomial CI estimation procedure. The PCA/t-test protocol should not be viewed as a “definite” test of unidimensionality and does not replace an integrated quantitative/qualitative interpretation based on an explicit variable definition in view of the perspective, context and purpose of measurement.
