Psychometric Properties of the Turkish Version of the Staffordshire Adolescent Idiopathic Scoliosis Questionnaire

Patient-Reported Outcome Measures (PROMs) have gained increasing importance in scoliosis research in recent years. Although widely used instruments such as the Scoliosis Research Society-22 (SRS-22) include domains related to body image, their primary purpose is to assess overall health-related quality of life and functional outcomes. In contrast, the Staffordshire Questionnaire for Adolescent Idiopathic Scoliosis (SQAIS) was specifically developed to provide a more detailed and patient-centered evaluation of body image and perceived deformity in individuals with adolescent idiopathic scoliosis (AIS). However, a Turkish version of the questionnaire with established validity and reliability is not currently available.

Therefore, the aim of the planned master's thesis is to conduct the cultural adaptation of the Staffordshire Questionnaire for Adolescent Idiopathic Scoliosis into Turkish and to evaluate its psychometric properties in adolescents with AIS. The study will involve a systematic process of linguistic translation and cross-cultural adaptation. Subsequently, the validity and reliability of the Turkish version will be assessed through analyses of internal consistency, test-retest reliability, construct validity, and criterion validity.

The findings of this study are expected to provide a valid and reliable instrument for assessing body image and deformity perception among Turkish adolescents with idiopathic scoliosis, thereby contributing an important patient-centered outcome measure to both clinical practice and research.

Treatment and study plan

Turkish Version of the Staffordshire Questionnaire for Adolescent Idiopathic Scoliosis (SQAIS)

Other

Administration of the Turkish version of the Staffordshire Questionnaire for Adolescent Idiopathic Scoliosis to evaluate body image and perceived deformity in adolescents with idiopathic scoliosis.

Primary outcomes

  1. Staffordshire Questionnaire for Adolescent Idiopathic Scoliosis

    Time frame: Baseline (Day 1) and 15-21 days after baseline.

    The Turkish version of the Staffordshire Questionnaire for Adolescent Idiopathic Scoliosis (SQAIS) will be administered to assess body image and perceived spinal deformity in adolescents with idiopathic scoliosis. The questionnaire consists of items evaluating patients' perceptions of their appearance and scoliosis-related concerns. Item scores are summed to obtain a total score. Higher scores indicate greater body image disturbance, poorer perception of appearance, and a greater perceived impact of scoliosis-related deformity. Test-retest reliability will be evaluated by re-administering the questionnaire 15-21 days after the initial assessment.

Secondary outcomes

  1. Scoliosis Research Society-22 Questionnaire

    Time frame: Baseline (Day 1)

    The Scoliosis Research Society-22 (SRS-22) questionnaire will be used to assess health-related quality of life in adolescents with idiopathic scoliosis. The questionnaire consists of 22 items distributed across five domains: Function/Activity, Pain, Self-Image/Appearance, Mental Health, and Satisfaction with Management. Items are scored on a 5-point Likert scale. Domain scores and a total score are calculated, with higher scores indicating better health-related quality of life, better function, less pain, more positive self-image, and better mental health.

  2. Spinal Appearance Questionnaire

    Time frame: Baseline (Day 1)

    The Spinal Appearance Questionnaire (SAQ) will be used to assess patients' perceptions of spinal deformity and body appearance related to scoliosis. The questionnaire consists of appearance-related items evaluating perceptions of trunk shape, posture, asymmetry, and overall spinal appearance. Scores are calculated for individual domains and as a total score. Higher scores indicate a more negative perception of spinal appearance and greater perceived deformity.
