This dissertation examined the relationships among disclosure, social support, exposure to violence, impulsivity, depression, stressors, and medication adherence, using a correlational design and a sequential logistic regression. The researcher used two samples of 146 from an archival data set of participants to create two subsets of the data (Data Set 1 & Data Set 2). These participants had been diagnosed with a mental illness and were prescribed a medication regimen for HIV treatment at the time of intake in a specialized clinic in Mexico City. Archival data was obtained through a demographic intake questionnaire and the use of valid and reliable instruments adapted for the specific population: State Impulsivity Scale (SIS) and the Beck Depression Inventory (BDI). Data analysis included descriptive statistics related to population demographics, bivariate correlations, and a sequential logistic regression based on existing literature on HIV/AIDS, medication adherence, and a theoretical model of stress and coping. Results of the analyses indicated that impulsivity was found to be predictive of medication nonadherence in Data Set 1 and exposure to violence was found to be predictive of medication nonadherence in Data Set 2. However, since both were not found to be significant across both subsets of the data, the variables could not be considered to robustly predict medication nonadherence in this study.
