Adaptation and Validation of the Voice Present Perceived Control Scale in Kannada

Area of Science:

• Speech-language pathology
• Psychological assessment
• Health sciences

Background:

• Present perceived control is an individual's ability to manage thoughts about stressful events.
• The Voice Present Perceived Control Scale (VPPCS) assesses stress and control related to voice disorders.
• No Kannada-language tool exists to evaluate the psychological impact of voice disorders.

Purpose of the Study:

• To adapt and validate the VPPCS in the Kannada language.
• To provide a culturally and linguistically equivalent measure for Kannada speakers.
• To facilitate early screening of psychological distress in voice disorder patients.

Main Methods:

• Translation and back-translation of the VPPCS by speech-language pathologists and a linguist.
• Content validation and cultural/linguistic equivalency assessment by expert speech-language pathologists.
• Administration of the Kannada version of VPPCS (KVPPCS) to 84 voice disorder patients and 84 healthy controls.

Main Results:

• The KVPPCS demonstrated good internal consistency and test-retest reliability.
• Known groups' discriminant validity was established for the KVPPCS.
• A cutoff score of 29.50 on the KVPPCS indicates reduced perceived control over psychological impact.

Conclusions:

• The KVPPCS is a reliable, self-reported tool for clinical use.
• It effectively measures perceived control in individuals with voice disorders.
• The KVPPCS can screen the psychological impact of voice disorders in Kannada-speaking populations.
