Design and Methods:This was a pilot randomized controlled trial (RCT) including 30 adults diagnosed with MS for at least one year. Participants were randomly assigned in equal numbers (1:1 ratio) to one of two groups:1. PCS Intervention group: 15 participants received eight weekly, 60-minute individual online sessions with a licensed clinical psychologist using WhatsApp video calls.2. Treatment-as-Usual (TAU) group: 15 participants continued their regular neurological and nursing care without additional psychological intervention.All participants completed questionnaires at baseline and at the end of the 8-week study to measure coping strategies, anxiety, and depression using validated Arabic versions of the Brief-COPE Scale and the Hopkins Symptom Checklist (HSCL-25). The PCS group also completed a self-developed Feasibility Questionnaire to assess the acceptability and practicality of the online sessions.Intervention Details:The PCS program was developed in Arabic by a multidisciplinary team including psychologists, nurses, and physicians. It was based on Lazarus and Folkman's Transactional Model of Stress and Coping (1984) and Problem-Solving Therapy principles. Each session included psychoeducation about healthy versus maladaptive coping, guided problem-solving exercises, and real-life applications through weekly homework. The sessions emphasized identifying challenges, generating solutions, weighing pros and cons, and implementing action plans
