Extending the Theory of Planned Behaviour: A SmartPLS Analysis of Postpartum Depression Awareness and Help-Seeking Behaviour in Niger State, Nigeria

Abstract

Background: Postpartum depression (PPD) is a persistent but under-diagnosed maternal mental health issue which contributes to emotional and physical stress in women. Hence, there is a need for interventions that can improve health and well-being for at-risk mothers. Objective: The aim is to examine how different sources of information impact PPD knowledge and help-seeking behaviour among women in Niger State. Methods: A cross-sectional survey was conducted, and Kobo Toolbox was utilised for data collection from 384 women. SmartPLS-SEM was used to test relationships among variables. Findings: reveal that interpersonal and electronic information sources significantly predict PPD awareness and help-seeking behaviour, while print media had a negligible effect. Conclusion: Multi-source, culturally sensitive strategies are critical in promoting PPD awareness (β = .55, p < .001) and help-seeking behaviour (β = .47, p < .001). Recommendation: The study underscores the need for culturally grounded communication strategies to improve maternal mental health literacy. Policy implications: Policymakers should integrate credible interpersonal and digital channels into maternal healthcare delivery to enhance awareness and reduce stigma.
