Speech-language pathologists' knowledge of genetics: perceived confidence, attitudes, knowledge acquisition and...

Area of Science:

• Genetics and Communication Disorders
• Speech-Language Pathology

Background:

• Genetics significantly impacts developmental and communication disabilities.
• Understanding genetics is crucial for speech-language pathologists (SLPs) serving affected children.
• Existing knowledge and confidence levels among SLPs regarding genetic disorders require investigation.

Purpose of the Study:

• To assess school-based SLPs' general knowledge of genetics.
• To evaluate SLPs' confidence and attitudes towards genetic disorder services.
• To identify SLPs' primary learning sources for genetic information and analyze factors associated with knowledge.

Main Methods:

• A nationwide survey was administered to 533 school-based speech-language pathologists (SLPs).
• Data collected included knowledge scores, confidence and attitude ratings, and caseload information.
• Statistical analyses were performed to determine associations between variables.

Main Results:

• SLPs achieved a median genetics knowledge score of 66%.
• Mean confidence and attitude ratings fell into the "unsure" category.
• Self-study, on-the-job training, and popular media were primary learning sources.
• Higher knowledge scores were positively associated with confidence, positive attitudes, and caseloads involving children with genetic disorders.

Conclusions:

• SLPs possess foundational genetics knowledge but require enhanced confidence and resources for genetic disorder services.
• Professional development and accessible information on genetics are vital for SLPs.
• The findings highlight the need for improved genetics education within speech-language pathology training programs.
