DYNHA SF-36 is a computerized adaptive test version of the SF-36 Health Survey. The feasibility of administering a modified DYNHA SF-36 to adults with HIV was evaluated with Johns Hopkins University Moore (HIV) Clinic patients (N=100) and Internet consumer health panel members (N=101). Participants completed the DYNHA SF-36, modified to capture seven health domains [(physical function (PF), role function (RF, without physical or emotional attribution), bodily pain (BP), general health, vitality (VT), social function (SF), mental health (MH)], and scored to produce two summary components [Physical Component Summary (PCS), Mental Component Summary (MCS)]. Item-response theory-based response consistency, precision, mean scores, and discriminant validity were examined. A higher percentage of Internet participants responded consistently to the DYNHA SF-36. For each domain, three standard deviations were covered with five items (90% reliability); however, RF and SF scores were less precise at the upper end of measurement (better functioning). Mean scores were slightly higher for the Internet sample, with the exception of VT and MCS. Clinic and Internet participants reporting an AIDS diagnosis had significantly lower mean PCS and PF scores than those without a diagnosis. Additionally, significantly lower RF and BP scores were found for Internet participants reporting an AIDS diagnosis. The measure was well accepted by the majority of participants, although Internet respondents provided lower ratings for the tool's usefulness. The DYNHA SF-36 has promise for measuring the impact of HIV and its treatment in both the clinic setting and through telemonitoring
