Background: It is well documented that individuals living with HIV experience varying levels of psychological distress symptoms throughout the progression of the disease. Additionally, depression is the most commonly documented symptoms reported in regards to this population. Little has been documented regarding the mental health status of individuals living with HIV throughout Africa. The purpose of this study was to find an appropriate measure of psychological distress symptoms to be utilized in a clinical environment in Western Kenya. Methods: This study was conducted with members of an established a support group network to measure the psychological distress symptoms of individuals living with HIV who self-seek support group care in this environment. Participants completed questionnaires that included both the Brief Symptom Inventory and the Patient Health Questionnaire-9 (n=396). Internal consistency measures were employed to measure the reliability of two scales that have previously been validated within HIV-infected and within clinical populations. Focus groups were conducted to understand the notion of measurement and further validate the meaning of the items on the two scales studied. Results: Internal consistency was measured by Cronbach's alpha coefficient for the BSI dimensions, which ranged from 0.62 for psychoticism to 0.77 for anxiety. The PHQ-9 resulted with a Cronbach's alpha coefficient of 0.78. Qualitative research findings offered an opportunity to further understand the complexities of self-reporting psychological distress symptoms. Conclusion: Validity and reliability testing of mental health assessments offer insight to understanding psychological distress symptoms and furthermore, how to improve the provision of care and treatment.
