Background: Adherence is an essential key to the effectiveness of antiretroviral (ARV) therapy. Motivational interviewing intervention is a method of therapy to en­hance intrinsic motivation in order to make behavior changes. This study aimed to exa­mine the effect of motivational interviewing intervention on motivation and adhe­rence to ARV therapy in people living with hiv/aids in Maumere, East Nusa Teng­gara. Subjects and Method: This was a quasi experiment with pre and post test. The study was conducted in Maumere, East Nusa Tenggara, Indonesia. A sample of 40 people li­ving with HIV/AIDS (plwh) was selected randomly. The dependent variables were motivation and adherence to ARV therapy. The independent variable was motivational inter­viewing intervention. The data were collected by questionnaire and analyzed by t test and Wilcoxon test. Results: Motivation on ARV therapy was higher after intervention (mean=42.50; SD=3.69) than before (mean=38.45; SD=4.186) and it was statistically significant (p= 0.010). ARV therapy adherence in PLWH after intervention (mean=3.85; SD=0.366) was higher than before (mean=3.10; SD=1.071) and it was statistically significant (p= 0.010).
