BackgroundQuality of life is the subject of growing interest and investigation.AimsTo develop and validate a short, self-report quality of life questionnaire (the Schizophrenia Quality of Life Scale, SQLS).MethodPeople with schizophrenia in Liverpool were recruited via the NHS. Items, generated from in-depth interviews, were developed into an 80-item self-report questionnaire. Data were factor analysed, and a shorter form measure was tested for reliability and validity. This measure was administered together with other self-report measures – SF–36, GHQ–12 and HADS – to assess validity.ResultsData were analysed to produce a final 30-item questionnaire, comprising three scales (‘psychosocial’, ‘motivation and energy’, and ‘symptoms and side-effects’) addressing different SQLS dimensions. Internal consistency reliability of the scale was found to be satisfactory. There was a high level of association with relevant SF–36, GHQ–12 and HADS scores.ConclusionsThe SQLS was completed within 5–10 minutes. It possesses internal reliability and construct validity, and promises to be a useful tool for the evaluation of new treatment regimes for people with schizophrenia.
