What this trial studies

Researchers will translate and culturally adapt the PASTUL questionnaire into Turkish using forward–backward translation and pilot feedback. They will enroll adults with scleroderma at Hacettepe University and have participants complete the Turkish PASTUL. The team will examine reliability (internal consistency and test–retest) and validity, including correlation with clinician-measured modified Rodnan Skin Score when available. The aim is to confirm the questionnaire's clarity, reliability, and suitability for routine use in the Turkish patient population.

Who should consider this trial

Good fit: Adults aged 18 or older with a diagnosis of scleroderma who are willing and able to complete questionnaires are ideal candidates.

Not a fit: Patients with advanced organ failure, major cognitive or neurological impairment, active malignancy, or those unwilling/unable to complete questionnaires are unlikely to benefit.

Why it matters

Potential benefit: If successful, Turkish patients could use a simple self-report tool to monitor skin thickness, supporting remote follow-up and earlier recognition of changes.

How similar studies have performed: The original PASTUL has been validated and shown to correlate with the modified Rodnan Skin Score, but this Turkish cultural adaptation has not previously been validated.
