Are online versions of family functioning questionnaires as reliable as paper-and-pencil versions in healthy individuals?
Effect estimate: MID < 0.5
Online versions of common family functioning questionnaires are reliable alternatives to traditional paper-and-pencil formats.
Lavorgna et al. (2020) conducted a cross-sectional in Healthy individuals (n=310). Online administration of questionnaires vs. Paper-and-pencil administration was evaluated on Minimum important difference (MID) in score variances between paper-and-pencil and online formats (MID < 0.5). Online administration of the Brief FAM-III, DAS, IPPA, TAS-20, HADS, and MSPSS questionnaires showed no significant difference in score variances compared to paper-and-pencil formats, with a minimum important difference <0.5 for all instruments.
