Background: Home health visits (HHV) are the new duty and development of students of applied Thai traditional medicine (ATM). We performed to develop a measuring instrument to ensure that students have positive attitudes to HHV. Objective: To develop a reliable and valid questionnaire for evaluating attitudes regarding home health visits among ATM students. Methods: There are 28 items in creating the questionnaire which is supposed to be used to assess attitudes toward HHV in four areas, including those related to the practice in HHV, the role of ATM practitioners, relationship with patients and patient’s relatives, and collaboration with the multidisciplinary team. Content validity of the questionnaire was assessed by three experts. Construct validity was analyzed with measurement model through linear structural relationship (LISREL). Thirty third-year ATM students were used to assess the questionnaire’s reliability. Test-retest reliability of the questionnaire was analyzed by intraclass correlation coefficient (ICC) using a two-way random-effect model with one-week intervals. Results: The final version of the questionnaire contains 32 questions, with 24 positive and 8 negative responses. Measurement model was best-fitted with a Chi-square of 2.77, P = 0.25, df = 2, GFI = 0.99 and RMSEA = 0.05. Cronbach’s alpha coefficients for all aspects ranged from 0.79 - 0.92. All aspects of ATM students’ attitudes related to HHV questionnaires were more significant than 0.80 except the attitudes related to the role of ATM practitioners, which was 0.79. They demonstrated an excellent test-retest reliability with an ICC of 0.90 (P < 0.001). The percentage of agreement on each item ranged from 0% to 96.7%. Conclusion: The developed questionnaire for evaluating ATM students’ attitudes on HHV has good validity and reliability for evaluating each aspect of ATM students’ attitudes.
