The aim of the study was to investigate the influence of personality traits, diagnosis and perceived coercion on patient satisfaction with inpatient psychiatric care. The study was performed as a cross-sectional study on 7 inpatient wards in southern Sweden. A cohort of 50 psychiatric inpatients evaluated satisfaction with care and also made ratings on a personality questionnaire. Patients with a higher level of the trait aggressive nonconformity were significantly less satisfied with the ward's physical and psychosocial environment, the treatment design and the treatment program. The phenomenon of acquiescence was not related to the reported level of satisfaction. Analyses of patient satisfaction according to diagnostic groups showed that patients with affective disorders had significantly better satisfaction than patients with a diagnosis of schizophrenia. Patients who perceived that they were involuntarily admitted were measured as being significantly less satisfied with the care in all areas. It is concluded that, to attain a higher specificity in analyses of variation in patient satisfaction, focus may be put on situational and setting factors of the care delivered along with specific patient characteristics. Risk groups, which require great attention in the development of quality assessment and quality assurance policies, are patients with schizophrenia and patients who perceive coercion in connection with inpatient psychiatric treatment.
