Abstract
Objective: To investigate whether the constructs of the Health Belief Model (HBM) can be applied to understand and predict adherence among HIV-positive pregnant women.
Methods: Cross-sectional study of 108 HIV-positive pregnant women attending 11 primary care clinics in Guyana. A questionnaire was administered on the constructs of the HBM as operationalized by the Adherence Determinants questionnaire (ADQ). Descriptions of the responses to the ADQ constructs were reported as numbers and percentages in each category. Responses to the ADQ constructs with adequate variation were tested for association with the level of adherence using Spearman’s rank correlation coefficient and test.
Results: There was little or no variation in 19/27 of the ADQ constructs as participants overwhelmingly endorsed one response. Only one item from the perceived susceptibility construct was significantly associated (p = 0.009) with adherence.
Conclusion: Although the ADQ was unable to measure the HBMs constructs within this population, theoretical models play an important role in explaining and understanding behaviour. Use of a larger sample is warranted to measure these constructs.
