 Mood disorders such as postpartum blue are very prevalent in the postnatal period, while the underlying mechanism of postpartum blue is not well known.
Aim
This research aimed to investigates the role of brain-behavioral systems activation in postpartum blue according to revised reinforcement sensitivity theory in mothers referring to Mashhad health-care centers.
Settings and Design
This correlational study has been conducted during February–March 2018, on 172 cases who diagnosed with postpartum blue were chosen through the purposive sampling method.
Materials and Methods
Participants completed demographic questionnaire, Jackson five-factor questionnaire, and the Edinburgh depression scale.
Statistical Analysis Used
The normality of data distribution examined using the Kolmogorov–Smirnov test. After, data were analyzed using descriptive methods (mean and standard deviation), Pearson confiscation, and stepwise regression method.
Results
The results showed that brain-behavioral systems, including behavioral inhibition system (BIS) (P < 0.001; R = 0.31) and behavioral activation system (BAS), had a significant correlation with postpartum blue (P < 0.05; R = 0.39), while there was no significant relationship between fight-flight systems with postpartum blue. BAS (R2 = 0.15,P < 0.05) and BIS (,R2 = 0.08,P < 0.001), the predictive potential of BIS and BAS was equal to 21% of variance of postpartum blue.
Conclusion
The findings suggest that behavioral-brain systems play a role in mothers' “postpartum psychological disorders such as postpartum blue and in the conception of mothers” distress after maternal delivery, the effects of these systems can be used in short-term interventions.
