A brief scale for assessing patients' satisfaction with care in outpatient psychiatric services

Objective: The authors evaluated the reliability and preliminary validity of the Charleston Psychiatric Outpatient Satisfaction Scale, a 15-item measure of patients' satisfaction designed for use in outpatient settings. The instrument uses a 5-point Likert-type response format that minimizes positive response bias and optimizes variability and predictive validity. Methods: The Charleston Psychiatric Outpatient Satisfaction Scale was administered to 282 patients seen in psychiatric outpatient clinics affiliated with a public-academic psychiatric institution over a one-week period in 1995. Results: The internal reliability of the instrument was high (alpha=.87), and its convergent validity was supported by the significant correlation of all items with anchor items that measured overall satisfaction with care and likelihood of recommending the clinic to others. The best predictors of overall ratings of care were the items measuring patients' satisfaction with helpfulness of the services and with the respect shown for patients' opinions about treatment. The best predictors of recommendation of the program to others were the items measuring satisfaction with matching of the treatment plan to patients' individual needs and with the respect shown for patients' opinions about treatment. Mean scores for all items ranged from 3.6 (satisfaction with parking) to 4.5 (satisfaction with helpfulness of the secretary and with the overall quality of care), indicating that overall satisfaction in this sample was high. Conclusions: The results provide preliminary support for the reliability and validity of the Charleston Psychiatric Outpatient Satisfaction Scale.
