摘要

After 2004, Taiwan experienced a sharp rise in AIDS/HIV cases among intravenous drug users (IDUs). Beginning in July 2006, a Needle Syringe Program (NSP) was implemented nationwide, and since then, the number of IDUs with HIV/AIDS infection has slowed. Understanding how the various stakeholders support this NSP is important in determining the success of the program. These stakeholders include the IDUs themselves, healthcare workers, and correctional workers including police, prosecutors and jailers. Since no information has ever been gathered to quantify the levels of support for the NSP, we developed a questionnaire for these three groups for future study. The questionnaire is based on the literature and consists of 6 items using three subscales (objections to the locations, worries about the program, and agreement with the program). The high scores on the questionnaire represent positive support for the NSP. The mean content validity index (CVI) from 10 experts was 77.8%. Recruitment for the study included IDUs (November to December, 2008), healthcare workers, and correctional workers (October to December, 2007). A total of 1345 valid and anonymous questionnaires was returned with a response rate of 85.6%. The scores for the three subscales and for the total reached statistical significance difference among the three study groups, indicating that our questionnaire has good known-groups of construct validity. Confirmatory factor analysis verified the appropriateness of the three factors for the questionnaire with goodness-of-fit index (GFI), adjusted goodness-of-fit index (AGFI), and normal fix index (NFI)＞ 0.9, root mean square error of approximation (RMSEA)=0.036, and composite reliability among each subscale＞ 0.5. Our questionnaire has an acceptable psychometric property, including good content validity, internal consistency, and construct validity. Other researchers are invited to use the questionnaire so that findings can be compared on the same basis.
