Introduction “International AIDS Questionnaire (IAQ)” was originally proposed by Davis in 1998 and has been used in Australia, China and the U.S. The IAQ enables to assess adolescent's awareness to HIV/AIDS by four factors; (1) misconceptions about HIV transmission, (2) prejudice/attitudes towards infected people, (3) personal risks and (4) factual knowledge about HIV/AIDS. The objective of this study was to validate the IAQ among Japanese adolescents.
Methods We developed the “International AIDS Questionnaire Japanese Version (IAQ-J)” by using back translation technique. IAQ-J was assessed on a sample of national high school students and private high school students from Eastern Japan. We conducted Exploratory and Confirmatory Factor Analysis and calculated Cronbach's α for total and each factor.
Results The results indicated that four-factor model was suitable to IAQ-J (GFI=0.903, AGFI=0.872). This result coincides to Chinese and English versions of IAQ. Total Cronbach's α of IAQ-J was 0.79. However, Cronbach's α for the “attitudes” factor was 0.66, indicating less reliable results. More than 70% of the students answered “no idea” to one question from the “attitudes” factor. After the exclusion of this item, Cronbach's α of the “attitudes” factor was raised to 0.75. This may indicate that this question was not appropriate for Japanese. Cronbach's α of the “factual knowledge” of IAQ-J was higher than other language versions of IAQ.
Conclusion IAQ is a simple and useful tool to assess the awareness on HIV/AIDS among adolescents. We recommend more language versions are tested and shared for international studies to prevent HIV/AIDS.
