ABSTRACT

 

Backgroud: HIV medication adherence is important to help people with HIV live longer and healthier. Taking HIV medicines every day prevents HIV from multiplying, which reduces the risk that HIV will mutate and produce drug-resistant HIV. Skipping HIV medicines allows HIV multiply, which increases the risk of drug resistance and HIV treatment failure. The IMB is a health behavioral change model that includes three primary constructs: (1) Information and knowledge about the behavior; (2) The individual’s motivation to perform the behavior; and (3) The behavioral skills necessary to perform the behavior. This study aimed to determine factors affecting adherence to antiretroviral therapy (ART) using IMB model among patients with HIV/AIDS. Subjects and Method: This was a cross-sectional study conducted at Amban Community Health Center in Manokwari, West Papua. A sample of 21 adolescents aged 15 – 24 years who were diagnosed with positive HIV and had undergone ART for least 3 months, was selected for this study. The dependent variable was ART medication adherence. The independent variables were information, motivation, and behavioral skills. The data were collected by the Standard Life Windows Information, Motivation, and Behaviour skills ART Adherence Questionnaire (LW-IMB-AAQ). The data were analyzed using simple logistic regression.

Results: Adherence to ART medication increased with better information (OR= 2.21; p= 0.023), stronger motivation (OR= 2.75; p= 0.008), and better medication taking skills (OR= 3.41; p= 0.027).

Conclusion: Adherence to ART medication increases with better information, stronger motivation, and better medication taking skills. Further studies with larger sample size are needed to allow the use of a better analysis model such as multiple logistic regression or path analysis.
