Objective: To assess the baseline characteristics associated with a greater risk of suicidal behaviour (suicide and parasuicide) over the 2 years following a first admission for psychosis, and the associations between suicidality and outcome.
Method: First-admitted subjects with psychosis (n=65) were assessed at 6-monthly intervals over a 2-year follow-up period.
Results: Over this period, 11.3% of the patients displayed suicidal behaviour. Baseline predictors of suicidal behaviour were a lifetime history of parasuicide before first admission (OR=5.9, 95% CI 1.5–23.4), lower Positive And Negative Symptom Scale positive subscores (OR=0.8, 95% CI 0.6–0.97) and a longer duration of first admission (OR=1.1, 95% CI 1–1.2). Subjects with suicidal behaviour presented with a longer duration of psychotic symptoms (OR=1.1, 95% CI 1.02–1.2) and a greater risk of being readmitted (OR=4.6, 95%CI 1.1–19.1). Subjects with substance misuse over the follow-up period were seven times (95%CI 1.3–39) more likely to engage in suicidal behaviour. Conclusion: Subjects with a previous history of parasuicide, with a deteriorating clinical course, or with substance misuse are at increased risk of suicidal behaviour in the 2 years after the onset of a first psychotic episode.
