Evaluation of a social work service for self-poisoning patients

Abstract

Four hundred patients aged at least 17 who came to Casualty in one year after deliberately poisoning themselves were randomly assigned between an Experimental social work service (task-centered casework) and a Control (routine) follow-up service. 139 patients were excluded from the trial, most of whom were already in continuing psychiatric treatment. After one year there was no difference in the proportions of E and C patients who repeated self-poisoning (about 14 per cent), but significantly more of the excluded group had repeated (36 per cent). A random half of the trial patients were re-interviewed four months after admission. Both E and C groups had improved to a significant extent on measures of depressed mood and of social problems. E patients showed more change in social problems and were more satisfied with the service they had received.
