Purpose: This study aims to evaluate the effectiveness of an Acceptance and Commitment Therapy-based group resilience intervention (The REsilience and Activities for every DaY program, READY) delivered to people with MS (PwMS) via frontline Italian services.
Materials and methods: This is a single-arm longitudinal study (with a nested qualitative study). READY is composed of seven weekly in-person sessions (2.5-h each) plus a booster session five weeks later. Data were collected immediately before the program, after the booster session, and at 3-months follow-up.
Results: Thirty-three READY groups (237 participants) were run by thirty-three trained psychologists. Participants improved in resilience (primary outcome), anxiety, depression, stress, health-related quality of life (HRQoL), and psychological flexibility and associated processes (acceptance, defusion, and values). Improvements on most outcomes occurred post-intervention and were maintained at a 3-month follow-up. No demographic or illness variables predicted these improvements. Psychological flexibility mediated improvements in resilience, anxiety, depression, stress, and HRQoL. Qualitative data confirmed READY feasibility and the positive psychological impacts on participants.
Conclusions: Study findings support READY effectiveness with PwMS, its broad applicability in this population, and its delivery through frontline services.IMPLICATIONS FOR REHABILITATIONREADY for MS is a highly structured, brief manualized group intervention.It is effective in improving participants' psychological functioning (resilience, anxiety, depression, stress, HRQoL, psychological flexibility, and related ACT processes).Psychological flexibility mediated the improvements in resilience, anxiety, depression, stress, HRQoL.READY can be effectively delivered through frontline services for PwMS without limitation in terms of participants' demographic and illness characteristics.
