The aim of this study was to validate the Communicative Participation Item Bank (CPIB), which specifically measures a disease's impact on daily conversational situations, as an outcome measure for SD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design<\/jats:title><jats:p>Multi\u2010institutional prospective cohort study.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A prospective study was conducted with administration of the 46\u2010question CPIB and the Voice Handicap Index\u201010 (VHI\u201010) to 190 participants with SD before (time 1) and 6\u2009weeks after (time 2) botulinum toxin injection. Differential item function (DIF) analyses were performed to examine potential item bias. Paired t\u2010tests were used to assess change in each of the CPIB and VHI\u201010 scores after treatment.
