Purpose: Postnatal depression has significant negative outcomes for both mother and baby. Cognitive-behavioural interventions have proven promising in its treatment, but there are a number of barriers, specific to the postnatal period, which lead to low take-up of treatment. Online interventions may circumvent some of these barriers. However, evidence of long-term follow-up is sparse, in spite of the importance of knowing how such treatments work over the longer-term. Methods: Long-term follow-up of postnatal women participating in a feasibility randomised controlled trial of NetmumsHWD, an online behavioural activation treatment with telephone support. Results: Retention rates of over 70 percent were obtained. There were small but non-significant effects of treatment on depressive symptomology and behavioural activation scores at 16 months post-randomisation. Baseline depression and behavioural activation scores predicted attrition prior to the implementation of outreach strategies for data collection; these systematic differences in attrition disappeared post-implementation. Measures of treatment adherence were not related to outcome. Conclusions: Collection of long-term follow-up data from postnatal women appears feasible. The findings demonstrate the importance of outreach in maximising retention, especially in relation to the generalizability of results. Future research should consider ways to assess treatment engagement and its relationship with outcome.
