An empirical test of the chronic illness quality of life model: the prominent role of barrier to health care and social support.

The Chronic Illness Quality of Life (CIQOL) model highlights satisfaction with life in individuals with a chronic illness (i.e., HIV-related diseases) determined by factors such as barriers to health care, AIDS-related discrimination, social support, physical well-being, and engagement coping. Despite the empirical evidence supporting the CIQOL model, its validation in the Iranian population has not yet been conducted. This study aimed to validate the CIQOL model among Iranian patients with HIV-related diseases. Four hundred fifty-two patients completed the study questionnaire including Barriers to Care Scale (BACS), Satisfaction with Life Scale (SWLS), Chronic Illness Anticipated Stigma Scale (CIASS), Social Provision Scale (SPS), The Functional Assessment of Human Immunodeficiency Virus Infection (FAHI), and the Brief COPE Scale. Structural equation modeling (SEM) was used to analyze the data. The assumed model demonstrated an acceptable level of fit to study data. Findings showed that this model could explain 39% of variances in life satisfaction in Iranian patients with HIV-related diseases. Therefore, in psychological interventions aimed at enhancing life satisfaction, the CIQOL model factors especially barriers to health care and social support can be taken into consideration.
