The development of the Thai Psychiatric Satisfaction Scale

Abstract

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.
