['Family caregivers of patients with psychiatric or medical disorders are at risk of developing psychological distress. Studies including family caregivers of patients with dementia have shown that psychoeducative programmes reduce distress and postpone institutionalisation. Little is known about the effect of psychoeducation of relatives of psychogeriatric patients. The aim of this study was to investigate the effect of a single-session educational intervention of relatives of psychogeriatric in-patients.', 'A randomised controlled intervention study was carried out with 16 relatives in the intervention group and 14 in the control group. The intervention was carried out as a single session programme. Primary outcome measures were psychological well-being and depression as measured by means of General Health Questionnaire (GHQ-30), Impact of Event Scale (IES) and Geriatric Depression Scale (GDS). Outcome measures were performed at baseline, at discharge and at 3-month follow-up.', "Psychological distress was high. Daughters were more depressed and distressed than spouses. Patients' diagnoses did not seem to exert influence on the relatives' well-being. There was a significant worsening of psychological distress in the intervention group as measured by GHQ-30."] Does single session educational programme for caregivers of psychogeriatric in-patients -- result from a randomised controlled pilot study?
