Objectives:
Preliminary evidence indicates that premenstrual dysphoric disorder (PMDD) may be frequently co-morbid with bipolar spectrum disorders. In addition, the manifestations of PMDD seem similar to a subthreshold depressive mixed state. Nevertheless, the associations between PMDD and affective temperaments and emotional traits have not been previously investigated.
Methods:
A consecutive sample of 514 drug-free Brazilian women (mean age: 22.8; SD=5.4years) took part in this cross-sectional study. Screening for PMDD was obtained with the validated Brazilian Portuguese version of the Premenstrual Symptoms Screening Tool (PSST). Affective temperaments and emotional dimensions were evaluated with the Affective and Emotional Composite Temperament Scale (AFECTS). In addition, socio-demographic and data on menstrual cycle were collected.
Results:
According to the PSST, 83 (16.1%) women screened positive for PMDD, while 216 (42.0%) women had no/mild premenstrual symptoms. The cyclothymic temperament was independently associated with PMDD (OR=4.57; 95% CI: 2.11-9.90), while the euthymic temperament had an independent association with a lower likelihood of a positive screening for PMDD (OR=0.28; 95% CI: 0.12-0.64). In addition, anger and sensitivity emerged as emotional dimensions significantly associated with PMDD.
Conclusions:
A positive screening for PMDD was associated with a predominant cyclothymic temperament, while an euthymic temperament was associated with a lower likelihood for a positive screening for PMDD. These data deserve replication in prospective studies.
