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.
Materials and Methods : 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 ∝ 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.
