Background: Behavioral intervention targeting speech, language, and communication concerns is an established therapeutic approach for patients with either acute or progressive communication concerns across a range of acquired neurogenic disorders. The multidimensional factors that contribute to a person’s self-identified communication challenges and strengths in their daily communication needs must be considered to provide functional and person-centered care. While many assessments grounded in clinician observation or client self-report have been developed to capture communication impairments, there is a direct need for a screening tool that comprehensively evaluates the roles of modality (verbal, text, gesture) and environment (in- person, virtual) on self-reported success across communicative demands.Aims: We describe and validate an approach to monitoring the progression of receptive and expressive communication skills in acquired neurogenic communication disorders in the context of communication practices of the 21st century, culminating in the development, implementation, and applications of a novel clinical instrument for this purpose: the Communication Success Screener (COMSS). Methods and Procedures: Thirty-three participants with acquired aphasia were recruited to complete and evaluate the COMSS via an online survey. Quantitative and open-ended participant feedback was used to validate and propose adaptations to the COMSS. Group level analyses and case presentations are used to highlight COMSS features and outcomes.Outcomes and Results: Participant responses to the COMSS questionnaire demonstrate that this screening tool creates differentiated communicative success profiles based on self-report. Participant feedback indicated that the COMSS appropriately evaluates self-reported success across modalities of verbal, written, and non-verbal expression in the context of in-person and virtual environments.Conclusions and Implications: Individuals with communication-led concerns often display heterogeneous language profiles with individualized functional communication concerns as a function of their daily activities of living and environmental supports. We introduce the COMSS as a valid tool to improve treatment goals and monitoring of functional change by evaluating self-reported communicative success as a function of form, modality, environment, and task demand.
