The aim of this study was to develop an integrative intervention, which combined Cognitive Behaviour Therapy (CBT), Body-Mind Therapy and Multicultural perspectives to assist health care workers in identifying and treating stress- related psychological disorders among people living with HIV and AIDS. The study employed an intervention research design using both qualitative and quantitative methods. The quantitative data was collected from PLHIV attending HIV Counselling and Testing (HCT) and Anti-retroviral therapy clinics in the Buffalo City Municipality (BCM) of the Eastern Cape Province. The qualitative data was collected from the health care workers of the selected study sites. Purposive sampling was used to select the study sample. Instruments used included a biographical questionnaire, the Beck Depression Inventory-II (BDI-II), Medical Outcome Study- HIV (MOS-HIV) and focus group interviews to gather data for the development of an intervention model that would address reported stress-related psychological disorders. Findings showed that people living with HIV and AIDS endure stress in their lives on daily basis rather than episodes of severe or clinical depression. Many of the PLHIV are dealing with a number of psychosocial problems that compromise their quality of life and health status. In conclusion, the study illustratively interpreted and discussed the results in relation to the objectives of the study. The study recommends that PLHIV should be exposed to stress management programmes, and health care workers (HCWs) should be offered training in basic counselling skills, stress management and/or debriefing.
