ACFP-DP was developed to assess parental attitudes, beliefs, and knowledge about pediatric pain. In this methodological cross-sectional study, an initial item pool was appraised by 7 of 20 invited experts and pilot-tested in 41 parents and guardians of hospitalized children. Experts rated clarity, pertinence, and relevance; I-CVI, S-CVI/Ave, and modified kappa coefficients were calculated. Mean I-CVI was 0.89 (range, 0.71-1.00), S-CVI/Ave values were 0.878 for clarity, 0.905 for pertinence, and 0.899 for relevance, and modified kappa ranged from 0.66 to 1.00. Overall self-reported comprehensibility was 94.9%. These findings provide preliminary evidence of content validity and high pilot comprehensibility, but not full psychometric validation. Further studies should assess reliability, structural validity, construct validity, and score interpretation before broader use.
Peñalver et al. (2026) studied this question.
