The daily experiences of persons living with HIV (PLWH) are important but under-studied as predictors of HIV prevention behavior. Ecological momentary assessment (EMA) is an intensive within-subjects data collection method that can be used to examine daily experiences. To determine whether PLWH would participate in EMA, we conducted a feasibility study with 21 PLWH. The method was acceptable to men and women from diverse backgrounds, with 81% (17/21) completing 2 months of daily surveys, and 67% (14/21) completing 6 months. Measures were completed on 72% of study days. Only 6% of records had missing data. Daily survey completion decreased over time. Participants reported that EMA was easy and did not influence their behaviors. Results suggest EMA is feasible with PLWH. © 2010 Wiley Periodicals, Inc. Res Nurs Health 33:221–234, 2010
