Abstract
Introduction: Given the high cost of AIDS, research on high-risk behaviors associated with AIDS is an essential requirement today. Therefore, the present study aimed to construct and standardize tests associated with AIDS-related risky behaviors.Methods: To assess the validity of the questionnaires, the experts’ viewpoints from different domains were qualitatively and quantitatively included. Additionally, to assess the reliability of the questionnaires, a sample of 31 subjects was selected and then examined on two separate occasions in a fortnight's time. Then, the validity and reliability of the instruments were assessed in a sample of 475 subjects.Results: The results of exploratory factor analysis showed that for AIDS health literacy and AIDS risk perception questionnaires two factors are extractable; while for the questionnaires of self-efficacy in controlling risk behavior and controlling risk behavior associated with AIDS one factor is extractable. Finally, 14 items were approved for each of the AIDS health literacy and self-efficacy in controlling risk behavior questionnaires; while 13 items were approved for each of the controlling risk behavior associated with AIDS and AIDS risk perception questionnaires. Each of the four questionnaires had a good internal consistency (Cronbach's Alpha > 0.70). Interclass Correlation Coefficient (ICC) amounts related to the test-retest reliability were greater than 0.80, which indicates the reliability of the instruments.Conclusion: According to the results of the present study, it was concluded that all four AIDS-related questionnaires enjoyed acceptable validity and reliability.
Highlights
Given the high cost of AIDS, research on high-risk behaviors associated with AIDS is an essential requirement today
The present project was a methodological study conducted on the residents of Kermanshah, Iran, to design and investigate the psychometric characteristics of four AIDSrelated questionnaires: AIDS health literacy, self-efficacy in controlling risk behaviors, AIDS risk perception, and controlling risk behaviors associated with AIDS
The number of items for each construct was as follows: 15 items for AIDS health literacy, 15 items for self-efficacy in controlling risk behaviors, 14 items for AIDS risk perception, and 16 items for controlling risk behaviors associated with AIDS
Summary
Given the high cost of AIDS, research on high-risk behaviors associated with AIDS is an essential requirement today. The present study aimed to construct and standardize tests associated with AIDS-related risky behaviors. The validity and reliability of the instruments were assessed in a sample of 475 subjects. Results: The results of exploratory factor analysis showed that for AIDS health literacy and AIDS risk perception questionnaires two factors are extractable; while for the questionnaires of selfefficacy in controlling risk behavior and controlling risk behavior associated with AIDS one factor is extractable. 14 items were approved for each of the AIDS health literacy and self-efficacy in controlling risk behavior questionnaires; while 13 items were approved for each of the controlling risk behavior associated with AIDS and AIDS risk perception questionnaires. 10 AIDS health literacy meant ‘one’s ability to receive, understand and interpret the basic information, measures to prevent HIV infection, and health-related services tailored to this end. Since risk behavior is associated with HIV infection, it is considered in public health programs
