Predicting Communicative Participation in Adults Across Communication Disorders

Area of Science:

• Speech-Language Pathology
• Rehabilitation Medicine
• Psycholinguistics

Background:

• Communication disorders significantly impact daily life.
• Understanding factors influencing communicative participation is crucial for effective intervention.
• Previous research has not comprehensively compared participation across diverse communication disorder diagnoses.

Purpose of the Study:

• To investigate differences in communicative participation across specific diagnoses.
• To identify common predictor variables for communicative participation across these diagnoses.
• To inform clinical practice by highlighting key psychosocial factors.

Main Methods:

• Survey data collected from 141 adults with Parkinson's disease, stroke, spasmodic dysphonia, or vocal fold immobility (VFI).
• Analysis of covariance used to compare communicative participation between diagnostic groups, controlling for covariates.
• Sequential linear regression analyzed associations between communicative participation and psychosocial variables.

Main Results:

• The vocal fold immobility (VFI) group exhibited significantly lower communicative participation compared to Parkinson's disease and spasmodic dysphonia groups.
• Self-rated speech/voice severity, effort, mental health, social support, and resilience predicted communicative participation across diagnoses.
• The influence of effort and resilience on communicative participation varied significantly by diagnosis.

Conclusions:

• Communicative participation restrictions differ across some, but not all, communication disorder diagnoses.
• Individuals with VFI experience more significant participation restrictions compared to other groups studied.
• While social support, severity, and mental health consistently relate to participation, effort and resilience play diagnosis-specific roles.
