The development of the Thai Psychiatric Satisfaction Scale.

BACKGROUND Satisfaction with mental services is an important quality and outcome variable. The Thai Psychiatric Satisfaction Scale (TPSS) is developed in order to measure service satisfaction. OBJECTIVE The purpose of the present study was to develop the Thai Psychiatric Satisfaction Scale (TPSS), having adequate and sufficient validity and reliability. MATERIAL AND METHOD A sample of people with mental illness in the Department of Psychiatry, Siriraj Hospital was assessed. The TPSS was administered. Then factor analysis, internal consistency and test-retest reliability were analized. RESULTS The Thai Psychiatric Satisfaction Scale (TPSS) contains seven domains: Professionals' Skills and Behavior, Information, Access, Efficacy, Type of Intervention, Relative's Involvement, and Environment and Setting. The infinity coefficient for the TPSS was 0.97 (95% CI 0.94-0.97) and ranged from 0.70 (95% CI 0.68-0.76) to 0.96 (95% CI 0.94-0.97). Test-retest for TPSS was 0.82. (95% CI 0.78-0.85). CONCLUSION This TPSS is a validated and reliable multi-dimensional scale which measures the satisfaction of patients with mental health services for routine clinical practice in mental health service.
