Cross-Cultural Adaptation and Psychometric Properties of the Malay Version of the Communication Skills Attitude Scale (CSAS) among Medical Students in Malaysia

Communication is one of the fundamental skills in the medical profession. The Communication Skills Attitude Scale (CSAS) is a widely used questionnaire to measure the attitudes of medical students toward learning communication skills. It has been adapted and translated into many languages. The objective of this study was to adapt and translate the CSAS into the Malay language and determine its psychometric properties in medical students. This is a cross-sectional study involving 218 first-year Universiti Teknologi MARA students. Content validation, cross-cultural adaptation, translation, and face validation of the 26-item CSAS were performed according to established guidelines. Principal component analysis with direct oblimin rotation was used to determine the underlying structure of the CSAS-Malay. The reliability was assessed using Cronbach's α coefficient for internal consistency and using the intraclass correlation coefficient for the test-retest reliability. Although the contents of the CSAS-Malay and the original version were conceptually equivalent, item 11 was removed during the content validation stage due to a low item content validity index (I-CVI < 1.00). Two subscales were derived from the remaining 25 items, which were the Positive Attitude Scale and the Negative Attitude Scale. Items 1 and 15 were removed due to poor factor loadings. The total variance explained by the final two-factor solution with three items removed was 30.8%. Cronbach's α coefficients for both the Positive and Negative Attitude Scales in the final questionnaire were 0.815 and 0.614, respectively. It also showed a good reproducibility with intraclass correlation coefficient (ICC) values of 0.725-0.950 for all the items. This study provided preliminary information about the psychometric properties of the CSAS-Malay. The final 23-item questionnaire had a good construct validity, an acceptable internal consistency, and at least a moderate test-retest reproducibility. It can be used to assess the attitudes of medical students toward learning communication skills. Future research to improve the generalizability of the questionnaire should include medical students from other universities with diverse backgrounds.
