Interpretive Summary:

Technical Abstract: Variables in the Model of Goal Directed Vegetable Parenting Practices (MGDVPP) have been shown to predict parents' use of effective vegetable parenting practices (EVPP). Psychometric analysis revealed the EVPP composite scale had three underlying subscales (responsiveness, structure, and non-directive control). It is important to examine whether the same MGDVPP variables predict each subscale or if there are differences in predictors among subscales and/or composite EVPP. This study presents the modeling of responsive, structure, and non-directive control EVPP using the MGDVPP. Parents (n=307) of preschool children completed an internet survey on MGDVPP items. Block regression modeling tested three models: One each with responsive, structure, and non-directive control EVPP as the dependent variable. Each MGDVPP variable (as scales with multiple subscales) was entered as predictors in separate and sequential blocks: Demographics, intention, intrinsic motivation, barriers, autonomy, relatedness, self-efficacy, habit, anticipated emotion, perceived behavioral control, attitude, and lastly norms. A habit subscale predicted responsive EVPP. Structure EVPP predictors included a barrier, two habit, and an attitude subscale. Several demographics, a habit, three intentions, and a perceived behavioral control subscale predicted nondirective control EVPP. The adjusted R2 for the final responsive, structure, and non-directive control EVPP models were 0.432, 0.310, and 0.515, respectively. This was the first study to test MGDVPP scales predicting the use of EVPP subscales. Further research is needed to assess the predictiveness of these subscales in longitudinal studies, their actual meaning to parents, and their utility in vegetable-related interventions.
