Our randomized double-blind longitudinal clinical trial on 14 menopausal women with high FSFI satisfaction scores following laser or RF vaginal interventions, demonstrated a high positive correlation between the subjects’ FSFI scores and the Hy (hysteria), D (Depression) and L (Lie) validity scales of the MMPI-2. Such high positive correlation between the FSFI and the L-scale negates the reported increase in female sexual satisfaction following laser or RF vaginal rejuvenations. The high positive correlations of the FSFI with the Hy and D scales indicate that despite reports of increased sexual satisfaction, the vaginal procedures did not improve psychological wellbeing or quality of life. Results on the Differential Emotions Scale (DES) reveal that 98% of the subjects were organized around the emotions of shame, sadness and joy. Such results indicated a multilayered emotional organization that possibly reflects joy on the outside and shame and sadness on the inside. Results of Laser or RF vaginal rejuvenation procedures should be evaluated by a battery of tests that take into account females’ often prominent tendency to focus on satisfying their partners rather than themselves. Going down the path that starts with a dismissal of self-fulfillment to focus on their partners’ satisfaction, may bring several women to the endpoint of disingenuous interpersonal relationships tainted by repressed disillusionment.展开更多

Methods： The Traditional Chinese Medicine Health Self-Evaluation Scale（TCM-50） was developed by verification of dimensions, formation of item pool, verification of scoring methodology, and pilot test of scale and item analysis. Results： TCM-50 composed of 50 items that could be classified into 4 dimensions including physiology and health, psychology and health, nature and health, and society and health. An examination of reliability and validity of TCM-50 yielded Cronbach＇s α coefficient of 0.927, and half coefficient of r was 0.876. The intraclass correlation coefficient of total score was 0.912. After using SF-36 questionnaire to evaluate the criterion validity, the Pearson r of the score of the two scales from the same participant was 0.740. Conclusions： TCM-50 has good reliability and validity, and can yield similar levels of efficacy as SF-36 in terms of evaluating people＇s overall health level. As a scale based on CM theory, TCM-50 is suitable for self-measuring the general health of Chinese patients.展开更多
