Development and preliminary validation of the Adolescent Food Parenting Questionnaire: Parent and adolescent version

Abstract Suitable instruments for measuring Food Parenting Practices (FPP) among adolescents and their parents that also measure the perception of adolescents about their parent's FPP are rare. The current study describes the development and preliminary testing of a short 16-item Adolescent Food Parenting Questionnaire (AFPQ) for parents (AFPQ-p) and adolescents (AFPQ-a) that may enable future large-scale research on potentially eminent parent-child FPP discrepancy. Participants included 381 parents (73.8 % mothers; Mage 45.9, 26.2% fathers; Mage 49.1) and their adolescent children (aged 12–16) who participated in the Dutch “G(F)OOD together” study. Most parents finished higher professional education (mothers: 44.3 %; fathers: 34.4 %) and performed a paid job of 32 h per week or more (mothers: 22.1 %; fathers: 60.0 %). The theoretical framework of Vaughn (2016) was leading in the development of the AFPQ. Exploratory factor analysis (EFA) was performed on a random split sample of parent-adolescent dyads and confirmatory factor analysis (CFA) was performed on the other half. The EFA in both parent and adolescent samples resulted in a clear 5 factor solution explaining 61.6 % (AFPQ-p) and 64.2 % (AFPQ-a) of the variance respectively, representing the factors Autonomy Support (α = 0.79/.82), Coercive Control (α = 0.85/.83), Snack Structure (α = 0.79/75), Healthy Structure (α = 0.78/74) and Modelling (α = 0.69/85). CFA confirmed good model fit for the AFPQ-p and the AFPQ-a. Associations with adolescent self-reported food intake were in the expected direction, confirming the preliminary convergent validity of the instrument among a moderate to highly educated group of parent-adolescent dyads. Although the AFPQ provides a promising short instrument, future research in more diverse samples is needed to build evidence on the instrument's psychometric characteristics in other groups.
