Powering up Family Systems Using Systems-Informed Positive Psychology

Abstract Abstract Promoting positive outcomes for children with disabilities and their families is a fundamental aim of family-centered care; however, a gap persists between the evidence and its implementation. To bridge this gap, this chapter explores the intersection of family systems theory and positive psychology, focusing on the role of systems-informed positive psychology (SIPP) as a means for positive change for children and their families. By questioning the traditional deficit- and expert-focused paradigms, the chapter highlights the need for alternative approaches to empower families and rebalance the parent–professional partnership. It outlines the increasing adoption of positive psychology in family-centered care and introduces SIPP as a framework to strengthen family systems theory, representing an advancement in family-centered care practices. Through a case study, the chapter illustrates the practical application of SIPP by utilizing parent-peer workers as levers of change, offering strengths-based emotional and psychological support that complements the role of nonpeer professionals. Guided by SIPP, these parent-peer workers facilitate a parenting program that incorporates positive psychology interventions to empower families and foster resilience. Finally, the chapter discusses the broader implications of SIPP in improving outcomes for children with disabilities and their families, emphasizing the potential for long-term positive impact at both individual and collective levels of family well-being.
