PHAS Assessment: Participants will complete the Postural Habits and Awareness Scale (PHAS) to assess postural awareness and habits. The scale will be administered twice, two weeks apart, to evaluate reliability.
Study summary
This observational, cross-sectional study aims to evaluate the reliability of the Postural Habits and Awareness Scale (PHAS) in patients with postural hyperkyphosis. The PHAS is designed to assess individuals' postural awareness and habits through four subscales. A total of 128 participants diagnosed with postural hyperkyphosis will complete the PHAS and the Kyphosis-Specific Spinal Appearance Questionnaire (KSSA). Test-retest reliability will be assessed by reapplying the PHAS after two weeks. Internal consistency, test-retest reliability, and concurrent validity will be analyzed. The study aims to provide a valid and reliable tool for evaluating postural awareness in clinical practice and future rehabilitation studies.

Inclusion Criteria:
* Age between 8 and 65 years
* Diagnosed with postural hyperkyphosis (Cobb angle ≥ 50° confirmed by clinical and radiological evaluation)
* Ability to perform daily activities independently
* Voluntary participation and signed informed consent
Exclusion Criteria:
* Presence of scoliosis or other spinal deformities
* Kyphosis due to severe osteoporosis or pathological fractures

* Cognitive impairment or severe psychiatric disorder preventing independent questionnaire completion
Primary outcome measure(s)
Reliability of the Postural Habits and Awareness Scale (PHAS) — 2 weeks Internal consistency will be evaluated using Cronbach's Alpha. Test-retest reliability will be assessed by calculating the Intraclass Correlation Coefficient (ICC) between two PHAS administrations. The PHAS consists of 19 items, each scored on a 5-point Likert scale (total score range: 19 to 95). Higher scores indicate better postural habits and awareness. Higher ICC values indicate better reliability.
