[Evaluation of affective temperaments in the postpartum depressive symptomatology]

Postpartum depression (PPD) is a frequent psychiatric condition, but little is known about its potential bipolar nature and the implication of affective temperaments. The goal of this study is to estimate the prevalence of PPD and assess the affective temperamental profile of those affected.

The study was conducted in the department of gynecology and obstetrics of the CHU of Sfax, Tunisia. The selected population included all 213 consecutive admissions (mean age=29 years). Postpartum depressive symptomatology (SPPD) was assessed during the first week after delivery by using the Postnatal Edinburgh Scale Depression (EPDS) in its Arab version. The Arabic version of the Temperaments Auto-questionnaire of Memphis, Pisa, Paris, and San Diego (TEMPS-A) was simultaneously filled out by subjects. The subjects were divided into two subgroups, depressed (D+) versus not depressed (D-), for comparative analyses. For affective temperaments, dimensional (mean scores) and categorical (quartiles) approaches were used.

Forty-one women (19,2%) had a score higher than 9 on the EPDS (group D+). Lower educational level, lower social and family support, dysfunctional marital relationship, problems with accepting the pregnancy and prior psychiatric disorders were significantly more present in the D+ group. The majority of the affective temperaments, excepting hyperthymic, were correlated between them. The EPDS scores were correlated with all temperamental scores, except for hyperthymic. Higher scores on the depressive, irritable, anxious and cyclothymic temperaments were observed in the group D+. Women belonging to the 3rd and 4th quartiles of the depressive, cyclothymic and irritable temperaments and those belonging to the 4th quartile of the anxious temperament were significantly more depressed. Cyclothymic and depressive temperaments seemed to influence the pregnancy acceptance. Other interactions were observed between SPPD, temperamental profiles and quality of marital relation, and family support. The opposite seems true for the hyperthymic temperament, which could be protective against SPPD through better psychosocial conditions. Multivariate regression analysis showed that cyclothymic and anxious temperaments are significant risk factors independently from psychosocial factors, such as problems with accepting the pregnancy, which seemed to be the most important risk factor.

PPD represents a frequent disorder, which needs to be correctly screened and recognized especially with its temperamental attributes, a mixture of anxious, irritable, depressive and cyclothymic traits. This complex unstable temperament should be considered as a predisposing factor, which interacts also with other common risk factors.
