Patient-based health status assessments in an outpatient psychiatry setting

Objective: The reliability, validity, and feasibility of the routine use of a generic health status instrument, the Short-Form-36 Health Survey (SF-36), were examined in a psychiatric outpatient clinic of a general hospital. Methods: The sample comprised 411 patients referred to an outpatient:psychiatry department between April 1994 and March 1995,They filled out the SF-36 along with their admission forms. Scores and reports were generated, and the results were returned to the charts and used at weekly clinical conference discussions. Feasibility-was evaluated using subjective and objective data on administration of the instrument, its psychometric properties, and costs. Results from the Outpatient psychiatry patients were compared with those from patients scheduled for elective surgery and a healthy normative sample. Results: Routine administration of the SF-36 was successfully achieved with minimal resistance:from staff and patients. The SF-36 provided reliable and valid data. As predicted, patients with emotional disorders scored lower, indicating more impairment, on scales measuring mental health than did the elective surgery patients and the normative sample. How ever, the psychiatric patients' scores on the physical health scale were lower than-clinicians expected. Compared with the elective surgery patients, the psychiatric patients were less impaired on only the physical functioning and-bodily pain scales; no difference was found between the two groups in role functioning due to physical problems, Conclusions: Routine use of the SF-36 in a general hospital psychiatric outpatient clinic was feasible, and the results were reliable, valid, and helpful to clinicians, Psychiatric patients' significantly lower scores in physical health and social and role functioning provided additional information about their difficulties.
