Summary
The Lidcombe Behavioral Data Language (LBDL) offers a new way to describe stuttering behaviors. Experienced clinicians showed good agreement using the LBDL, suggesting its potential for stuttering research and therapy.
Area of Science:
- Speech-language pathology
- Behavioral science
Background:
- Current stuttering research often focuses on disfluencies rather than stuttering itself.
- Existing descriptive systems lack a behavioral basis.
- The Lidcombe Behavioral Data Language (LBDL) was developed to address these gaps.
Purpose of the Study:
- To investigate the reliability of the Lidcombe Behavioral Data Language (LBDL).
- To assess both intrajudge and interjudge agreement for the LBDL.
- To evaluate the LBDL's utility in categorizing stuttering behaviors.
Main Methods:
- Ten speech-language pathologists and 10 undergraduate students were trained in the LBDL.
- Participants applied the LBDL to 15 speech samples from children and adults on two separate occasions.
- Intrajudge and interjudge agreement scores were calculated.
Main Results:
- High intrajudge agreement was observed in both experienced and novice groups.
- Only experienced speech-language pathologists achieved satisfactory interjudge agreement.
- Certain stuttering behaviors appeared easier to categorize than others using the LBDL.
Conclusions:
- The LBDL demonstrates good intrajudge reliability across different experience levels.
- Interjudge reliability with the LBDL is satisfactory among experienced clinicians.
- The LBDL shows promise for application in stuttering research and clinical practice.
