Multinomial Logistic Regression: Predictors of Mental Health Profiles
We performed a multinational logistic regression analysis with mental health profile as the dependent variable and age, BMI, hirsutism, acne, education level, marital status, cognitive reappraisal, expressive suppression, and social support as independent variables. The complete mental health profile was used as the reference group for regression analysis. Table 3 shows the multinational logistic regression results. Acne was a significant predictor of being classified as a mental health profile. Compared with the complete mental health profile, the odds of being in the symptomatic but content profile was 0.58 for PCOS women with acne compared with PCOS women without acne. Therefore, in this sample, PCOS women with acne were 1/0.58 = 1.72 times more likely to be in a symptomatic but content profile rather than a complete mental health profile than PCOS women without acne.
More importantly, the odds of being in a symptomatic but content profile (rather than a complete mental health profile) were 1.06 for women with PCOS with higher expression suppression relative to PCOS women with lower expression suppression. Likewise, PCOS women with higher expression suppression had 1.17 odds of being in a troubled profile (as opposed to a complete mental health profile) relative to women with PCOS with lower expression suppression. In addition, social support significantly predicted profile classification in women with PCOS. Compared with the complete mental health profile, for each unit increase in social support, the probability of being classified as a symptomatic but content profile (Odds Ratio = 0.93, p < 0.01) or a troubled profile (Odds Ratio = 0.90, p < 0.01) decreased. In other words, for every unit increase in social support, the possibility of PCOS women in a complete mental health profile is 1/0.93=1.08 times that of a symptomatic but content profile, and the possibility of a complete mental health profile is a troubled profile 1/0.90=1.11 times. Finally, cognitive reappraisal was not essential in predicting the classification between symptomatic but content profile and complete mental health profile. However, for each unit increase in cognitive reappraisal, women with PCOS were 1/0.88=1.14 times more likely to be in the complete mental health profile than in the troubled profile (Odds Ratio = 0.88, p < 0.01).
