Longitudinal association of intimate partner violence and depressive symptoms
Purpose: The association between intimate partner violence (IPV) and depression has been well established in cross-sectional research, but how IPV is associated with depressive symptoms over time has not been well studied.
Methods: Using the Central Pennsylvania Women's
Health Study, a population-based longitudinal survey of women aged 18–45 (N = 1,420), we performed a two-step logistic regression analysis. In step 1, the association of recent IPV exposure at baseline with depressive symptoms 2 years later was analysed adjusting for relevant
covariates; in step 2, we additionally included positive coping strategies (social support, physical activity) and negative coping strategies (binge drinking/drug use, smoking) in the model.
Results: Baseline IPV was reported by 4.6 percent of the sample and was independently associated
with depressive symptoms 2 years later (adjusted or 1.88, 95% confidence interval [CI] 1.02–3.45). The strongest predictor was depressive symptoms at baseline, which was associated with a fivefold increase in the likelihood of depressive symptoms at 2-year follow-up. Other predictors
of future depressive symptoms were IPV at follow-up, older age, lower educational attainment, and lower household income. When we controlled for potential coping strategies in the model (step 2), the relationship between recent IPV and follow-up depressive symptoms was attenuated (adjusted
OR 1.50, 95% CI 0.80–2.80).
Conclusions: Exposure to IPV increases the likelihood of depressive symptoms occurring two years later. Greater social support and binge drinking/drug use attenuates this association, suggesting that interventions focusing on coping mechanisms may
serve to reduce the impact of IPV on future depression.
