  Abstract: Objective Reliability and validity test of the Chinese version of Beliefs About Medical Questionnaire -Specific (BMQ - Specific) in HIV/AIDS patients receiving Highly Active Anti-retroviral Treatment（HAART）. Methods From November to December in 2021,570 HIV/AIDS patients receiving HAART in 3 clinical treatment sites were selected according to the prevalence of HIV in Yunnan Province. I-CVI, S-CVI were used to test content validity and item analysis was used to each item. Structural validity was tested by Exploratory Factor Analysis and Confirmatory Factor Analysis.Criterion validity was measured by the Morisky medication adherence scale 8-item version.Cronbachs α, CITC, IDα , retest reliability were used to test reliability. Results BMQ-Specific had good discrimination, and the correlations between score of each item and the respective dimension total score ranged from 0.647~0.819.The results of exploratory factor analysis and validation confirmatory factor analysis showed that the model fitting indicators were within the standard range (χ2/df=2.063，CFI=0.959，GFI=0.953，TLI=0.946，RMSEA=0.061，SRMR=0.061).The I-CVI of each item was between 0.800 to 1.000, and the S-CVI was 0.970. BMQ-Specific scores were significantly correlated with the MMAS-8. Reliability analysis showed that the Cronbach α of dimensions of necessity and concern were 0.844 and 0.800 respectively, and the CITC values of 10 items in the two dimensions were lager than 0.5，The test-retest reliability of the two dimensions with for-week interval was 0.786 and 0.753. Conclusion The Chinese version of BMQ-specific had proved its good applicability in HIV/AIDS patients receiving HAART.
