While in some studies differences between these administration formats were observed other studies did not show statistically significant differences important to patients. Since the evidence about the effect of administration format is inconsistent and mainly available from cross-sectional studies our aim was to assess the effects of different administration formats on repeated measurements of patient-reported outcomes in participants with AIDS enrolled in the Longitudinal Study of Ocular Complications of AIDS. Methods We included participants enrolled in the Longitudinal Study of Ocular Complications in AIDS LSOCA who completed the Medical Outcome Study MOS -HIV questionnaire the EuroQol the Feeling Thermometer and the Visual Function Questionnaire VFQ 25 every six months thereafter using self- or interviewer-administration. A large print questionnaire was available for participants with visual impairment. Considering all measurements over time and adjusting for patient and study site characteristics we used linear models to compare HRQL scores all scores from 0-100 between administration formats. We defined adjusted differences of standard deviations SD to be quantitatively meaningful. Results We included 2 261 participants males with a median of years of age at enrolment who provided data on 23 420 study visits. The .
