This study was heavily based on experiential expertise. It interviewed 24 people with lived experience of psychosocial disability and NDIS plans, included researchers with lived experience, and used a Lived Experience Advisory Group to co-design the study, analyse themes, and validate findings. The methodology explicitly positioned participants as experts on their own conditions and service needs.

The document has limited direct practice wisdom. While it captures some practitioner perspectives through participant accounts of ED clinician behaviors and NDIS worker interactions, it doesn't systematically gather practice wisdom from healthcare professionals themselves. The study notes a "nationwide survey of ED clinicians was conducted in 2023" but will be "reported elsewhere." The research primarily focuses on service user experiences rather than professional practice insights.

This study is extensively based on research and evaluation insights. It conducts a systematic qualitative study using established research methodologies (thematic analysis, COREQ standards), extensively references prior research on NDIS and ED integration challenges, and situates findings within broader literature. The study follows rigorous research protocols including ethics approval, reflexive analysis, and trustworthiness criteria to evaluate service integration gaps.
