Application of Self-determination Theory to Illness Self-management Interventions: Identifying Mediators.

NIMH requires intervention research to utilize an experimental therapeutic approach, identifying mediators to examine causal mechanisms of change. The authors propose utilizing self-determination theory (SDT) to guide research design for self-management interventions, using Wellness Recovery Action Plan (WRAP) as an exemplar. To delineate the theory's relevance to self-management interventions and recovery outcomes, the authors describe the main constructs of SDT and demonstrate its applicability to WRAP and recovery. Suggestions for research design and measurement strategies are provided.
