            This research was a descriptive study. The aim of study was to investigating the reliability and exploratory factor analysis of a Thai version short form of The Patient Activation Measure (PAM). The evidence base was used in the context that was suitable for Thai people relying on the standardized translation process. Translations were done from original to Thai version. And then the content validity was checked by 5 experts. The reliability of the translated Thai version was examined by distributing questionnaire to 300 patients with orthopaedics disease. The statistical analysis was used for the reliability and exploratory factor analysis.

            The result of this study found a Thai version short form of PAM could be translated into Thai without major difficulties. The overall Cronbach’s alpha coefficient of the PAM Thai version was .74 and item-total correlations were .71 - .83. Thai version of PAM achieved a good level of reliability. The results of the exploration factor analysis by using Kaiser-Myer-Olkin’s measures of sampling adequacy (KMO) was .85. Bartlett's test of sphericity statistics showed that the chi-Square (χ2) statistic was 916.10, which had a statistically significant level at .05. The elements could be extracted in 4 components. The value of eigen is between 1.06-4.23 and the cumulative variance was 58.18%. Finally, the research demonstrated that the translated of PAM Thai version is suitable for use in Thai patients with orthopaedics disease.
