Elimination of restrictive practices (physical/mechanical restraint and seclusion) from adult acute mental health care services has been demanded internationally for many decades. This study aimed to: (1) Identify priority issues in the elimination of and use of alternative approaches to restrictive practices (seclusion and physical/mechanical restraint) in rural/regional acute adult mental healthcare services, as told by mental healthcare service users and practitioners, (2) identify the community-based, system-level feedback loops that enhance or reduce the use of restrictive practices and viable alternatives and, (3) identify potential action areas to improve system structures to increase regional mental healthcare services' ability to eliminate restrictive practices and use alternative approaches. Group model building (GMB) workshops were held with a small group (n = 9) of mental healthcare practitioners and service users with lived experience of restrictive practice use. This participatory approach enables exploration and visual mapping of local structures causing behaviour patterns of practitioner and service user concern over time - in this case, the barriers, and enablers to alternative approaches to restrictive practices in adult acute mental healthcare services within the Geelong-Barwon region. This is the first study that specifically applies GMB in the discussion of the elimination of restrictive practices in mental health in the non-metropolitan regional/rural context. Participants identified four key priorities in relation to eliminating restrictive practices: (1) self-advocacy, (2) continuity of care, (3) early intervention, and (4) safety for all. The study findings were distilled into a novel preliminary set of mental healthcare practitioner and service user action ideas.
