Aims:Stunting is a persistent nutritional condition caused by inadequate nutrient intake over time, which negatively impacts children’s growth. This study aimed to develop a psychoeducational model for mothers with children who have growth and developmental deviations, focusing on feeding infants and young children. Instrument & Methods:This observational study used the Infant and young child feeding model to assess the stunting prevention aspect. Data were collected using a Likert-scale assessment instrument, which was reviewed to determine its usefulness in standardizing documentation of psychoeducation prevention based on the elements of the infant and young child feeding model. Analysis was conducted using structural equation modeling-partial least squares. Findings: Maternal characteristics (β=0.589; p=0.022), knowledge (β=0.741; p=0.034), health (β=0.716; p=0.033), nutritional status (β=0.591; p=0.016), exclusive breastfeeding (β=0.769; p=0.037), environmental sanitation (β=0.651; p=0.018), and husband’s support (β=0.691; p=0.027) were significantly related to outcomes. Conclusion: The infant and young child feeding model demonstrates strong predictive power and validity in explaining the psychoeducational model.
