Predictors of perception of cognitive functioning in HIV/AIDS

Area of Science:

• Neuroscience
• Psychology
• Public Health

Background:

• Perceived cognitive functioning is a critical aspect of quality of life for individuals living with HIV/AIDS.
• Understanding predictors of cognitive function is essential for developing targeted interventions.

Purpose of the Study:

• To identify predictors of perceived cognitive functioning in a large, multi-site sample of nonhospitalized individuals with HIV/AIDS.
• To determine the proportion of variance in cognitive function explained by demographic, disease, symptom, and functional status variables.

Main Methods:

• A descriptive, correlational study utilizing self-reported measures from 728 participants across seven US sites.
• Hierarchical multiple regression analysis was employed to assess the contribution of various factors to perceived cognitive functioning.
• Key measures included the Medical Outcomes Study HIV scale for cognitive function and the Sign and Symptom Checklist for Persons with HIV Disease.

Main Results:

• Demographic, disease, symptom, and functional status variables collectively explained 36.3% of the variance in perceived cognitive functioning.
• Symptom status emerged as the most significant predictor, accounting for 26.5% of the variance.
• Depression, specifically, explained 28% of the variance in cognitive functioning among a subset of participants.

Conclusions:

• Symptom burden is a primary driver of perceived cognitive impairment in the HIV/AIDS population.
• Early identification and management of symptoms are crucial for improving cognitive function and quality of life.
• Clinical interventions targeting remediable conditions can positively impact individuals living with HIV/AIDS.
