Implementation of Family Involvement for Persons With Psychotic Disorders.

This study will develop and evaluate a complex intervention to implement guidelines on family involvement for patients with psychotic disorders (F20-29 in International Classification of Diseases ICD-10) in community mental health centres, by using a cluster randomised design. Fifteen Norwegian outpatient units participate in the study, and each of them constitutes a single cluster, except for two collaborating clinics who are considered one cluster. Of the fourteen clusters, half will receive implementation support and training immediately, whereas the other half will receive it one and a half year later. The study will assess both service level outcomes, by measuring fidelity scores, and selected outcomes for patients and relatives, by collecting questionnaires and data from central health registers and patient records. In addition, qualitative interviews will be performed with patients, relatives and health care personnel. The study will also include a cost-effectiveness analysis and a political economy analysis.
