Is day hospital treatment effective, and can success be predicted?

Clinical improvement is demonstrated in a group of 41 day patients of mixed diagnosis by changes in measures of depression, self-esteem, loquacity and sociability over a period of six weeks. Staff predictions of success, made after 2 weeks, correlated positively (Spearman's rho = 0.53) with an overall assessment of success after 6 weeks, which itself was positively correlated with improvements in scores on depression (rho = 0.58) and sociability (rho = 0.66 and 0.60). The patients for whom staff predicted least success were in 6 cases out of 7 men aged 20-51.
