that contains the constructs of Health Belief Model (HBM), and also to analyse HIV
testing intention and behaviour among university students.
The mixed method approach was used in phases. First, Literature review and in-depth interviews were
conducted to develop item pool for HTBS, which was followed by content validity assessment by
experts. In the second phase, a pilot survey was conducted on randomly selected 318 university
students to refine the HTBS using item analysis and Exploratory Factor Analysis (EFA). Lastly,
cross-sectional survey was conducted on representative sample of 612 students in order to further
refine the HTBS using Confirmatory Factor Analysis (CFA) and also analyse predictors of HIV testing
intention and behaviour. A total of 61 items was written for the HTBS and 23 of these were generated from the
in-depth interviews. Content validity assessment by three experts indicated that the average
content validity index (CVI) for the 61 items was 91.2% which was more than the recommended cut off
point of 90%. The HTBS, after experts review, contained 64 items.
EFA indicated that a five factor model which was roughly consistent with HBM was identified and 44
items were retained based on factor loading and reliability analysis. The Cronbach’s alpha for all
the six constructs of HBM and HIV testing intention in the HTBS were >0,70.
(susceptibility, benefit, self-efficacy and HIV testing intention) fitted the sample data based on
chi-square test. However, all the seven constructs demonstrated RMSEA value of less than 0.08 and
GFI value of >0.90 indicating acceptable fit. The final HTBS was reduced to 39 items based on
factor loading and reliability assessment. All the constructs demonstrated a Cronbach’s alpha value
>0.70 except for perceived susceptibility and cues to action.
Analysis of multiple linear regression indicated that class year, perceived benefit, perceived
self-efficacy and cues to action were significant predictors of HIV testing intention. However,
only marital status and cues to action were significant predictors of recent history of HIV testing
through analysis of binary logistic regression. / Health Studies / D.Litt. et Phil. (Health Studies)
