Description
Objective: This study evaluated the content validity, internal consistency and stability of a questionnaire designed to assess the HIV/AIDS knowledge of young adults. Methods: The questionnaire was administered on two occasions, within two week intervals, to 219 university students in the USA (n=66), Turkey (n=53) and South Africa (n=100). The psychometric instrument contained demographic information questions and 45 knowledge questions regarding the HIV virus, ways of transmitting it, symptoms of HIV/AIDS infection and methods of prevention. Factor analysis was conducted to assess construct validity; Cronbach alphas and Pearson's product moment correlation (r) were calculated to evaluate internal consistency and stability, respectively. Results: The 45 knowledge questions produced a Kaiser-Meyer-Olkin (measure of sampling adequacy) value of 0.8133 and loaded on three factors with an overall Cronbach's alpha of 0.861. The r for the individual knowledge question was greater than 0.50 and the overall knowledge score was "almost perfect" (0.91; p<.001). For participating students from the USA, Turkey and South Africa, their r for the overall knowledge score was 0.80 (p<.001), 0.83 (p<.001) and 0.93 (p<.001), respectively. Conclusions: Our findings revealed that the instrument is highly stable and internally consistent. The availability of this instrument may enhance HIV intervention studies internationally. © JA Balogun, TC Aniona, M Lukobo-Durrell, A Adefuye, S Amosun, J Frantz, Y Yakut, 2010.
