The participants were women scoring &lt;12 on the postal Edinburgh Postnatal Depression Scale (EPDS) at 6 weeks postnatally (1474 intervention and 767 control women). Intervention HVs (<jats:italic>n</jats:italic>=89, 63 clusters) were trained in identifying depressive symptoms using the EPDS and face-to-face clinical assessment and in providing psychologically orientated sessions based on cognitive behavioral or person-centered principles. The control group comprised HVs (<jats:italic>n</jats:italic>=49, 37 clusters) providing care as usual (CAU). The primary outcome measure was the proportion of women scoring ⩾12 on the EPDS at 6 months postnatally. Secondary outcomes were mean EPDS score, Clinical Outcomes in Routine Evaluation – Outcome Measure (CORE-OM) score, State–Trait Anxiety Inventory (STAI), 12-item Short Form Health Survey (SF-12) and Parenting Stress Index Short Form (PSI-SF) scores at 6, 12 and 18 months.</jats:p></jats:sec><jats:sec id="S0033291710001467_sec_a003" sec-type="results"><jats:title>Results</jats:title><jats:p>After adjusting for individual-level covariates, living alone, previous postnatal depression (PND), the presence of one or more adverse life events and the 6-week EPDS score, the odds ratio (OR) for EPDS ⩾12 at 6 months was 0.71 [95% confidence interval (CI) 0.53–0.97, <jats:italic>p</jats:italic>=0.031] for the intervention group (IG) women compared with the control (CAU) group women. Two subgroups were formed by baseline severity: a ‘subthreshold’ subgroup with a 6-week EPDS score of 6–11 (<jats:italic>n</jats:italic>=999) and a ‘lowest severity’ subgroup with a 6-week EPDS score of 0–5 (<jats:italic>n</jats:italic>=1242).
