AIMS: This observational study compared data values, reliability, consistency and compliance collected by electronic and paper diaries of differing durations. METHODS: Subjects >= 18 years with @entity2182 ( @entity2182 ) on stable antimuscarinic treatment for >= 12 weeks were assigned to one of five, 15-week diary schedules in this randomized, parallel-group observational study. Sample size was sufficient to assess reliability and consistency of diary data with adequate precision. Reliability was assessed via intraclass correlation coefficients, variability with ANCOVAs, and consistency using Cronbach's alpha. RESULTS: Demographic characteristics of randomized subjects were representative of @entity2182 trial populations. For mean volume voided, reliability was comparable across diary groups. For @entity322 , reliability improved with increasing diary duration. For micturition frequency, electronic 7-day diary results had highest reliability and lowest variability. Lowest overall reliability was observed in the 3-day paper diary. Consistency was highest in the electronic continuous groups; Cont A (daily measurements throughout the study period [fully Continuous]) and Cont B (daily measurements for some but not all endpoints of interest [Partially Continuous]). Compliance was generally high; across groups >= 90% of diaries had at least one entry per day. There was no significant change in average micturition frequency with diary duration, suggesting no diary fatigue. One-third of subjects in the electronic Cont B group also reported micturitions as @entity322 when they only needed to report @entity322 ; they also reported lowest satisfaction with the study. The electronic 7-day and electronic Cont A schedules (who reported @entity322 and micturitions throughout the study) had lowest residual errors. CONCLUSIONS: For future @entity2182 trials, 7-day or continuous electronic diaries may improve accuracy and @entity1163 and @entity322 frequency data compared with shorter collection periods and paper diaries.
