First, we identified the main sources where consumers acquire or seek information about miniature automobiles and discussed their extent of information search. Then, based on logistic regression and optimal scaling regression of statistics, we studied the influences of characteristics of consumers of miniature automobiles on the extent of information search and on Internet usage. The results indicate that consumers often utilize four sources to obtain information about miniature automobiles. The dominant information source for consumers is their friends/family, followed by dealers, newspapers, and TV. Age, occupation, education and income significantly affect the extent of information search, but gender and city of residence do not have significant impacts. Age, city of residence, occupation, education and income produce significant influences on Internet usage. Gender has an insignificant influence on whether a consumer uses the Internet to search for information.展开更多

A convenience sample of 79 persons (47 men and 32 women) was recruited from The Heart and Lung Patients’ National Association at ten local meeting places in different areas in Sweden. The questionnaire was examined for face and content validity, internal consistency and test-retest reliability. The findings showed that the Swedish version of KHOS is acceptable in terms of face and content validity, internal consistency and test-retest reliability over time among 79 individuals >65 years of age and with a cardiac disease. In conclusion, wider evaluations of the psychometric use of KHOS for other populations and settings are recommended.展开更多
