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).
