The Lidcombe Behavioral Data Language of stuttering.

The Lidcombe Behavioral Data Language (LBDL; K. Bryant & A. Packman, 1999; A. Packman & M. Onslow, 1998; A. Packman, M. Onslow, & K. Bryant, 2000) is a recently developed taxonomy of stuttering. It fills a void in stuttering research because most current descriptive systems are taxonomies of disfluencies, not stuttering alone, and are not behaviorally based. This study is an investigation of intrajudge and interjudge agreement for the LBDL. Ten experienced speech-language pathologists and 10 undergraduate students received brief instruction in the LBDL and then applied it to 15 intervals of stuttered speech on 2 occasions. The speakers were children and adults. Intrajudge agreement was high for both groups but only experienced judges achieved satisfactory interjudge agreement. Results suggest that some stuttering behaviors may be easier to categorize than others. Possible applications of the LBDL to research and clinical practice in stuttering are discussed.
