We sought to investigate the associations of regaining capacity to make treatment decisions following approximately 1 month of in-patient psychiatric treatment.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291710000383_sec_a002\"><jats:title>Method<\/jats:title><jats:p>We followed up 115 consecutive patients admitted to a psychiatric hospital who were judged to lack capacity to make treatment decisions at the point of hospitalization. We were primarily interested in whether the diagnosis of schizophrenia and schizoaffective disorder associated with reduced chances of regaining capacity compared with other diagnoses and whether affective symptoms on admission associated with increased chances of regaining capacity. In addition, we examined how change in insight was associated with regaining capacity in schizophrenia, bipolar affective disorder (BPAD)-mania, and depression.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291710000383_sec_a003\" sec-type=\"results\"><jats:title>Results<\/jats:title><jats:p>We found evidence that the category of \u2018schizophrenia or schizoaffective disorder\u2019 associated with not regaining capacity at 1 month compared with BPAD-mania [odds ratio (OR) 3.62, 95% confidence intervals (CI) 1.13\u201311.6] and depression (OR 5.35, 95% CI 1.47\u20139.55) and that affective symptoms on admission associated with regaining capacity (OR 1.23, 95% CI 1.02\u20131.48).
