With depression known to impede HIV care adherence and retention, we examined whether depression alleviation improves these disease management behaviors. A sample of 1028 depressed HIV clients in Uganda enrolled in a cluster randomized controlled trial of two depression care models, and were surveyed over 12 months. Serial regression analyses examined whether depression alleviation was associated with self-reported antiretroviral therapy (ART) adherence and clinic attendance at month 12, and whether these relationships were mediated by self-efficacy and motivation. Among those with major depression, depression alleviation was associated with better ART adherence and clinic attendance at month 12; these relationships were fully mediated by self-efficacy at month 12, while adherence motivation partially mediated the relationship between depression alleviation and ART adherence. When both mediators were entered simultaneously, only self-efficacy was a significant predictor and still fully mediated the relationship between depression alleviation and adherence. These findings suggest that depression alleviation benefits both ART adherence and clinic attendance, in large part through improved confidence and motivation to engage in these disease management behaviors.
