Positive behaviour intervention and support (PBIS) models are evolving as an effective means to promote social and emotional competence among young children and address challenging behaviours. This study was designed to gain insights into parental involvement in programme-wide implementation of the Pyramid model. Interviews were conducted with seven parents to examine: (a) parents' knowledge of social and emotional strategies; (b) which social and emotional strategies parents find useful; and (c) parents' communication preferences for obtaining information about social and emotional strategies. Interviews were guided by community-engaged research principles, which allowed a contextual understanding of data through the lens of various stakeholders. The results revealed that parents had varied knowledge about social and emotional strategies and were interested in strategies that were practical and easy to access. Implications for practitioners and policy-makers supporting parental involvement in programme-wide PBIS efforts for young children are discussed. (author abstract)
