Integrating Acceptance and Commitment Therapy with intervention mapping to enhance self-care in type 2 diabetes: a conceptual framework.

Self-care in type 2 diabetes mellitus (T2DM) remains suboptimal despite evidence for the effectiveness of Acceptance and Commitment Therapy (ACT) in chronic illness management. This conceptual paper integrates ACT-based psychological flexibility processes with Steps 1-4 of the Intervention Mapping framework to develop a brief, replicable group intervention for primary care. Acceptance, cognitive defusion, and values clarification are specified as modifiable determinants of barriers in self-monitoring, diet, exercise, and medication adherence, organized into performance-determinant matrices to guide method selection. Theory-based methods are operationalized through culturally adaptable metaphors and experiential exercises. This framework addresses methodological gaps in translating ACT to diabetes care, aligns with biopsychosocial models in health psychology, and offers a testable foundation for future randomized trials on multicultural efficacy.
