Abstract
Over the past 50 years, mental health services have evolved significantly, influenced by shifts in theoretical and practical approaches to mental disorders. Key among these changes are the biopsychosocial and recovery models, which highlight resilience and quality of life in treatment. However, traditional psychiatry has often struggled to embrace these changes because of reductionist perspectives that overlook psychosocial factors, resulting in fragmented care and reduced accessibility. Proposed solutions have faced implementation barriers in absence of a coherent theoretical framework. Here, we outline how attachment theory may offer a promising framework to drive systemic change in mental health by emphasising secure emotional bonds at both the organisational and individual level. Within an attachment-informed culture, services may act as 'organisational caregivers' that promote continuity of care, independence and stronger clinical relationships. In turn, this may foster more inclusive, responsive and resilient mental healthcare systems that prioritise patients' needs and empowerment.
