Statistical analysis examined depression prevalence, treatment outcomes, and associated social factors. The research leveraged survey data and longitudinal studies to identify key predictors and inform mental health program development.
The decision behind the question
A mental health programme needed to know which social and clinical factors predicted depression outcomes so that limited programme capacity could be directed usefully.
Data and methods used
Survey instruments and longitudinal follow-up data were analyzed together, with prediction models ranking outcome predictors and relationship analysis separating direct effects from effects travelling through social support.
What the analysis found
- •Social support acted as an intermediate factor carrying much of the influence attributed to other variables.
- •Prevalence differed across population groups in ways that a single overall rate concealed.
- •Early follow-up scores predicted longer-term outcomes well enough to guide triage.
What changed as a result
Programme intake was reorganised around early follow-up scores and social support, which are the points where the programme could actually intervene.
