Abstract: This study aims to develop and validate a Chinese version of the Patients Expectation Scale (PES) for use in Hong Kong. The PES is a self-administered questionnaire for measurement of different scopes of patients' expectations to treatment outcome. Content validity of the PES was completed by our collaborators. Fifty subjects with back pain were recruited in this study of construct validity and evaluation of reliability. Multitrait scaling analysis of the PES revealed a three factor-structure, which include the Working Alliance, Proxy Efficacy and Motivation/ Expectation subscales. High correlation was found for Working Alli ance and Proxy Efficacy subscales (r = 0.68). Scores of Proxy Efficacy subscale had significant correlations with treatment outcome measured by SF-36 (r = -0.361 for Mental Component Summary and r = -0.342 for Social functioning) but not with VAS. Reliability study showed that PES subscales are highly internally consistent (Cronbach alpha of Working Alliance = 0.958; Cronbach alpha of Proxy Efficacy = 0.925; Cronbach alpha of Motivation/ Expectation = 0.946). The Chinese version of PES is considered a valid and reliable instrument for local use in Hong Kong.
