Patient-reported outcomes (PROs) are essential in patient-centered, evidence-based practice in speech-language pathology. PROs respect individuals who live with communication disorders as key stakeholders providing a critically unique perspective on consequences of communication disorders, and whether interventions bring about meaningful changes. Some PROs focus on specific communication symptoms such as voice or language symptom severity, while others focus on broader constructs such as quality of life. Many PROs target specific diagnostic groups. This article presents the Communicative Participation Item Bank (CPIB), a PRO that measures communicative participation restrictions. The CPIB was based on the concept of participation, or engagement in life situations, as defined in the World Health Organization's International Classification of Functioning, Disability, and Health. It was designed to be relevant for adults across different communication disorders to facilitate clinical and research activities that may involve either comparing or aggregating data across communication disorders. The CPIB follows current PRO development protocols including systematic guidance from stakeholders through cognitive interviews, and the measurement methods of Item Response Theory that allow precise and adaptive assessment. This article reviews use of the CPIB across different diagnostic groups, and identifies needs for future efforts to expand the relevance of the CPIB further.
