Abstract
OBJECTIVE: To describe: a) a self-report questionnaire of 34 item, developed by a Family Association of Psychiatric Patients in collaboration with two psychiatrists to evaluate by key-relative in a clinical practice the perceived quality of mental health services, the needs and family burden; b) the methodology of validation. METHODS: It has been studied (a) the Face Validity by two focus groups of 10 relatives for each group, (b) the concurrent validity of family burden items comparing the ABC with QPF, a widely used questionnaire, in 6 Italian mental health centres on a sample of key-relatives, (c) the discriminant validity comparing three different samples of key-relatives of patients with psychiatric illness, Alzheimer or cancer. The internal consistency of items for assessing relatives' opinions on the quality of care has been evaluated by Chronbach' s alpha. The test-retest has been evaluated on a sample of 20 key-relatives. RESULTS: The results indicate a fairly good performance of the questionnaire in this preliminary but almost complete phase of validation. The time to fill in it has been estimated in a 7 minutes average. CONCLUSION: It is possible by this self-report questionnaire to evaluate in a clinical routine setting and in a very short time three important problems for relatives and professionals: opinions and needs of relatives, and objective and subjective family burden of severe mental illness.
