Show moreFamilies with multiple needs across life domains often deal with a multitude of professionals from various organizations. This frequently results in fragmented support. In theory, integrated care is considered the ultimate solution to overcome this fragmentation in Youth Care. However, in practice, providing integrated care is easier said than done. Consequently, professionals, organizations, and policy makers struggle to implement an integrated approach. It is becoming increasingly clear that integrated care requires more than merging organizations or establishing multidisciplinary teams. Many scholars claim that it is a necessity to evaluate integrated care in real-life settings, and thereby unravel facilitators and barriers for professionals.This dissertation aims to increase understanding of facilitators and barriers for professionals to provide integrated care from various perspectives: a systematic literature review, semi-structured interviews with professionals and parents, and an action-based research study in integrated care teams in the Netherlands. With the outcomes of this dissertation, clinical and research practices will be better informed about the complexity of integrated care on a professional level. Show less
