Usability and Perceived Persuasiveness in Pediatric Oral Care
Description
1) Study overview and design This dataset comes from a randomized two-period AB/BA within-subject crossover human factors evaluation. Each participant experienced both conditions: Condition A (Control) and Condition B (eHealth) within a standardized protocol. The repository includes (i) paired subjective construct scores for both conditions (N=181) and (ii) a video-coded behavioral subsample (N=32) with task-level records for tasks T1–T5. 2) Research hypotheses (mapped to variables) H1 (condition main effect): Compared with Condition A, Condition B improves key subjective mechanism indicators (e.g., perceived usability satisfaction, perceived persuasiveness, self-efficacy) and yields better task performance (higher completion, shorter time, fewer errors and assistance). Variables: PUS/PP/SE (primary), PA/PU/PC (secondary), and behavioral metrics (completion/time/error/assist). H2 (age-related differences): The magnitude of the condition effect may vary by developmental stage (age group). Variables: age_group + B–A differences for subjective and behavioral outcomes. PC as a key “negative” result with equivalence testing: Perceived credibility (PC) is expected to show no meaningful change; therefore, an equivalence test (TOST) is provided in addition to a difference test. Variables: PC scores under A and B; TOST based on paired differences (B−A).
