Validity and Reliability of the Behavioral Regulation in Exercise Questionnaire-2 (BREQ-2) in Adolescents With Idiopathic Scoliosis

Starting soon

Conditions studied: Adolescence Idiopathic Scoliosis

In brief

Adolescent idiopathic scoliosis (AIS) is a spinal condition that develops during adolescence and often requires long-term conservative treatment, including scoliosis-specific therapeutic exercises. The success of exercise-based treatment largely depends on adolescents' motivation to start and continue exercising. However, exercise motivation has not been adequately evaluated in adolescents with idiopathic scoliosis using validated tools specific to this population. The Behavioral Regulation in Exercise Questionnaire-2 (BREQ-2) is a widely used questionnaire based on Self-Determination Theory that assesses different types of motivation toward exercise. Although the Turkish version of the BREQ-2 exists, its validity and reliability have not yet been examined in adolescents with idiopathic scoliosis. The purpose of this study is to evaluate the validity and reliability of the Turkish version of the BREQ-2 in adolescents diagnosed with idiopathic scoliosis. Adolescents aged 10-19 years who have been participating in scoliosis-specific therapeutic exercise programs for at least two months will be invited to complete online questionnaires. The results of this study will help determine whether the BREQ-2 is an appropriate tool for assessing exercise motivation in this population and may support the development of individualized motivational strategies in scoliosis rehabilitation.
