Integrated Motivational Interviewing and Rational Emotive Behavior Therapy Intervention for Non-Suicidal Self-Injury Among Malaysian Primary School Students: A Feasibility Trial Protocol

This study aims to evaluate the feasibility and preliminary effects of the MIND-SET Intervention Module, an integrated Motivational Interviewing and Rational Emotive Behavior Therapy (MI-REBT) intervention, among Malaysian primary school students involved in Non-Suicidal Self-Injury (NSSI) behaviour. The module is designed to reduce self-injurious behaviour, improve emotional regulation, and enhance readiness for change among 12-year-old students in school settings. This study will use a quasi-experimental design involving three groups: a MIND-SET intervention group, a PRISMA Mental Health Module group, and a treatment-as-usual group. Data will be collected at pre-intervention, post-intervention, and follow-up stages using validated psychological instruments. The findings are expected to support the development of culturally responsive, school-based mental health interventions for children involved in NSSI behaviour in Malaysia.

Inclusion Criteria: * Primary school students aged 12 years old. * Students identified with Non-Suicidal Self-Injury (NSSI) behaviour through school mental health screening and assessment procedures. * Able to understand and participate in group counselling sessions. * Written informed consent obtained from parents or guardians. * Assent obtained from participating students. Exclusion Criteria: * Students currently receiving intensive psychiatric treatment or psychological -intervention for severe mental health conditions. * Students identified with active suicidal intent requiring immediate clinical intervention. * Students with severe cognitive or developmental impairments that may interfere with participation in group intervention activities. * Students who are unable to attend the scheduled intervention sessions consistently.
