Turkish Validation of the Synkinesis Assessment Questionnaire (SAQ)

Sponsor: Barış CELBEK

View on ClinicalTrials.gov

Summary

Peripheral facial palsy may result in synkinesis, a condition characterized by involuntary facial muscle movements that occur during voluntary facial expressions. Synkinesis can negatively affect facial function, appearance, and quality of life. The Synkinesis Assessment Questionnaire (SAQ) is a patient-reported outcome measure developed to assess the severity and impact of synkinesis. However, a validated Turkish version is not currently available. The aim of this study is to translate and culturally adapt the SAQ into Turkish and to evaluate its validity and reliability in Turkish-speaking adults with peripheral facial palsy and synkinesis. The Turkish version will be developed using a standardized forward-backward translation process. Participants will complete the Turkish SAQ and the Facial Disability Index (FDI). Reliability, internal consistency, and construct validity will be evaluated to determine whether the Turkish SAQ is a valid and reliable instrument for clinical practice and research.

Synkinesis Assessment Questionnaire (SAQ)

Participants will complete the Turkish version of the Synkinesis Assessment Questionnaire (SAQ), developed through a standardized forward-backward translation and cross-cultural adaptation process. The questionnaire consists of nine patient-reported items assessing the frequency and severity of synkinetic facial movements during daily activities. Participants will also complete the Facial Disability Index (FDI) during the initial assessment. To evaluate test-retest reliability, the Turkish SAQ will be administered again one week after the baseline assessment.
