Effect of a Self-Management Intervention for Patients Newly Diagnosed With Inflammatory Arthritis: The NISMA Trial

The NISMA intervention is a flexible intervention and comprises three mandatory individual sessions with a nurse, supplemented by two optional group sessions over a period of 12 months, to provide comprehensive support tailored to each participant's needs. The intervention is grounded in the theoretical framework Social Cognitive Theory and inspired by the questioning techniques in Acceptance and Commitment Therapy (ACT). These methods play a crucial role in helping participants enhance their self-efficacy. The key components of our approach include: a person-centered approach by addressing challenges identified by each participant to foster self-efficacy through targeted problem-solving and goal-setting. This is utilized by interviewing techniques derived from ACT to assist participants in accepting and committing to self-management. The program is designed to last between 6-12 months, allowing for gradual skill development and adaptation.
