Clinical observations have linked antiretroviral nonadherence to treatment regimen fatigue in persons living with HIV (PLWH). Although nonadherence appears to be a consequence of treatment regimen fatigue, little is known about the onset, course, and duration of this construct. Our study developed and evaluated psychometric properties of a measure of treatment regimen fatigue for PLWH. Based on a recent review, the concept was hypothesized to reflect decreased motivation, treatment cynicism, and low self-efficacy to adhere to treatment. Items comprising these factors were generated based on measures of similar constructs in the literature. Exploratory factor analyses suggested that a two-factor solution best fit the data and accounted for 35.8% of the variance. Our study supported a two-factor model of treatment regimen fatigue consisting of Treatment Cynicism and Self-Efficacy. The scale provides a new tool to assess treatment regimen fatigue in PLWH and can be used to inform and improve treatment of HIV.
