Behavior Assessment Battery: Normative and Psychometric Investigation Among Polish Adults Who Do and Do Not Stutter.

Purpose: The aim of this study was to establish normative data for Polish persons who stutter (PWS) and persons who do not stutter (PWNS) with the adapted version of the Behavior Assessment Battery (BAB; Vanryckeghem & Brutten, 2018) for adults and to investigate whether or not gender and age influenced the results. In addition, the BAB subtests' reliability and validity were examined.

Method: A Polish version of the BAB test procedures, including the Speech Situation Checklist-Emotional Reaction, Speech Situation Checklist-Speech Disruption, Behavior Checklist, and Communication Attitude Test for Adults Who Stutter (Vanryckeghem & Brutten, 2018), were individually administered to 123 adults who stutter and 151 adults who do not stutter between the ages of 17 and 70.
