Between Personality Traits and Postpartum Depression: The Mediated Role of Maternal Self-Efficacy

The Influence of Personality Traits on Postpartum Depression: A Systematic Review Based on the NEO-FFI Scale

Postpartum depression (PPD) is a significant global health concern with profound implications for mothers, families, and societies. This systematic review aims to synthesize current research findings to understand better how personality traits, as assessed by the NEO Five-Factor Inventory (NEO-FFI), contribute to the development and progression of PPD. Conducted in January 2024, this review searched major databases like PubMed, PsycINFO, and Scopus up to December 2023, focusing on the NEO-FFI's role in evaluating PPD. Following PRISMA guidelines, studies were selected based on strict criteria, including the exclusive use of NEO-FFI for personality assessment and a focus on postpartum women. A total of seven studies were included after a rigorous two-step screening process, and their data were qualitatively synthesized. The review covered a total of 4172 participants, with a prevalence of clinically significant postpartum depression symptoms ranging from 10.6% to 51.7%. Notably, Neuroticism emerged as a significant predictor of PPD, with odds ratios ranging from 1.07 (95% CI: 0.96-1.20) in some studies to as high as 1.87 (95% CI: 1.53-2.27) in others. In contrast, traits like Extraversion and Conscientiousness generally showed protective effects, with lower scores associated with reduced PPD risk. For instance, Extraversion scores correlated negatively with PPD risk (Beta = -0.171) in one study. However, the impact of other traits such as Openness and Agreeableness on PPD risk was less clear, with some studies indicating negligible effects. The review highlights Neuroticism as a consistent and significant predictor of PPD risk, with varying impacts from other personality traits. The findings suggest potential pathways for targeted interventions in maternal mental health care, emphasizing the need for comprehensive personality evaluations in prenatal and postnatal settings.

Evaluation of the Impact of a Midwife-Led Breastfeeding Group Intervention on Prevention of Postpartum Depression: A Multicentre Randomised Clinical Trial

Postpartum depression is a significant health issue affecting both mothers and newborns during the postpartum period. Group support interventions during this period have proven effective in helping women cope with depression and improving breastfeeding rates. This study aimed to assess the effectiveness of a midwife-led breastfeeding support group intervention on breastfeeding rates, postpartum depression and general self-efficacy. This was a multicentric cluster randomised controlled trial with control and intervention groups and was not blinded. It was conducted in Andalusia (southern Spain) from October 2021 to May 2023. A total of 382 women participated in the study. The results showed a significant difference in exclusive breastfeeding rates at 4 months postpartum between the groups (control 50% vs. intervention 69.9%; p < 0.001). Additionally, there was a lower mean score on the Edinburgh Postnatal Depression Scale in the intervention group (12.49 ± 3.6 vs. 13.39 ± 4.0; p = 0.044). Similarly, higher scores of general self-efficacy were observed among breastfeeding women at 2 and 4 months postpartum (77.73 ± 14.81; p = 0.002 and 76.46 ± 15.26; p < 0.001, respectively). In conclusion, midwife-led breastfeeding support groups enhanced self-efficacy, prolonged breastfeeding and reduced postpartum depression 4 months after giving birth.

Social Support, Parenting Self-Efficacy, and Postpartum Depression Among Chinese Parents: The Actor-Partner Interdependence Mediation Model

INTRODUCTION

Postpartum depression affects both mothers and fathers. This study aimed to examine the relationships between social support, parenting self-efficacy, and postpartum depression in Chinese mothers and fathers and assess the mediating effect of parenting self-efficacy using a dyadic perspective.

METHODS

A cross-sectional study was implemented from December 2020 to July 2021 in Guangzhou, China, with 309 pairs of parents. The Edinburgh Postnatal Depression Scale, Social Support Rating Scale, Parenting Sense of Competence Scale-Efficacy subscale, and sociodemographic data sheet were completed by both parents. Dyadic analysis was conducted using the actor-partner interdependence mediation model. An actor effect is the relationship between variables within an individual, whereas a partner effect is the relationship between variables in the individual and the dyadic partner.

RESULTS

In total, 20.7% of mothers and 11.7% of fathers had elevated postpartum depressive symptoms at 6 weeks postpartum. The model revealed 6 actor effects: social support was positively associated with parenting self-efficacy for mothers (β, 0.39; 95% CI, 0.28-0.49) and fathers (β, 0.39; 95% CI, 0.30-0.48) and negatively associated with postpartum depression for mothers (β, -0.22; 95% CI, -0.32 to -0.12) and fathers (β, -0.37; 95% CI, -0.48 to -0.26). Parenting self-efficacy was negatively associated with postpartum depression in mothers (β, -0.41; 95% CI, -0.53 to -0.29) and fathers (β, -0.24; 95% CI, -0.37 to -0.12). Maternal social support had a partner effect on paternal parenting self-efficacy (β, 0.14; 95% CI, 0.04-0.24). Parenting self-efficacy mediated between social support and postpartum depression for both parents (mothers: β, -0.16; 95% CI, -0.23 to -0.10; fathers: β, -0.10; 95% CI, -0.16 to -0.05).

DISCUSSION

Postpartum depression was a dyadic phenomenon. Increasing mother-centered social support has the potential to improve the parenting self-efficacy of both parents and reduce the likelihood of postpartum depression.

Intolerance to uncertainty and self-efficacy as mediators between personality traits and adjustment disorder in the face of the COVID-19 pandemic

In April 2020, early in the COVID-19 outbreak, governments restricted public gatherings and ordered social distancing. These demands led to challenging adaptations, which in some cases resulted in mental health issues, including adjustment disorder. Guided by the transactional stress model, the current study aimed to examine the relations between personality traits and adjustment disorder in crisis situations and vagueness and the role of intolerance to uncertainty and self-efficacy in these relations. During Israel's first lockdown, 673 Israeli adults completed self-reported e-version questionnaires regarding Big Five personality traits, adjustment disorder, intolerance to uncertainty, self-efficacy, and background variables. The study was designed to examine the association between personality traits and adjustment disorder and the potential mediation of intolerance to uncertainty and self-efficacy in associations. The findings revealed that intolerance to uncertainty and self-efficacy mediated the association between personality traits and adjustment disorder. The results are consistent with the transactional stress model. They shed light on the role of intolerance to uncertainty and self-efficacy as cognitive mechanisms that promote the development of adjustment disorder. Recommendations for future studies and practice are discussed.

Support Needs for Anxiety among Pregnant Women in Japan: A Qualitative Pilot Study

Support needs for pregnancy-related anxiety among low-risk pregnant women remain unclear. This study aimed to clarify the kinds of support for anxiety that women seek during pregnancy in Japan. Data were collected in a semi-structured focus group interview involving five pregnant women who were not in specific risk groups, recruited from three facilities in Tokyo. We generated themes using inductive thematic analysis. This paper adhered to the consolidated criteria for reporting qualitative research. From the data on support needs for anxiety during pregnancy, three themes were derived: (1) seeking tailored professional support; (2) seeking continuous support within informal relationships; and (3) seeking others’ success stories in the same situation. These three types of support gave participants a sense of reassurance or raised concern, depending on the situation. We proposed a model comprising the three derived themes using social cognitive theory. We discussed how these three types of support influenced pregnant women’s self-efficacy, which is the core concept of the social cognitive theory. Our findings may help to plan theory-based research and effective interventions to provide support for women’s anxiety during pregnancy using a population approach. Our results also demonstrated the importance of collaboration with pregnant women in developing further research and interventions.
