Objectives: To assess (1) preference of parental use of an electronic diary (e-diary) over a paper diary to record continuous infant and caregiver behaviors over 7 days; (2) whether e-diary recordings would differ in systematic ways from those obtained by paper diaries, and (3) frequency of diary entries when parents provide entries when convenient.
Methods: Mothers of normal newborns were randomized at 5 weeks infant age to a paper diary first (n = 34) or e-diary first (n = 35) group. With 3 days between, mothers completed 7-day recordings on both the paper Baby's Day Diary and an analogous personal digital assistant e-diary for infant (sleep, awake alert, feeding, fussing, crying, inconsolable crying) and caregiver (carrying/holding, moving) behaviors, and completed post diary ease-of-use ratings and poststudy preference ratings.
Results: Mothers found e-diaries less bothersome but similarly disruptive and enjoyable to paper diaries. At study end, more found e-diaries easier to use, less bothersome and more efficient. E-diary behaviors were consistently more frequent, but rarely different in duration, then paper diary behaviors. Time-stamped e-diary entries (1) generally declined across weeks, (2) were higher if e-diaries were used first, and (3) settled at a modal 2 to 3 entries/day by the second week.
Conclusions: For behavioral recording of infant and caregiver behaviors, mothers generally expressed more approval for e-diaries than paper diaries, but neither was considered onerous. E-diaries consistently report more frequent but similar durations of behaviors. If recording when convenient, daily diary entries trend toward 2 to 3 entries a day. The e-diary results provide convergent evidence that paper diary recordings of common infant and caregiver behavior durations provide good estimates of durations, but that behavioral frequencies may be underestimated.
