Measuring impact of augmentative and alternative communication interventions: adapting the family impact of assistive technology scale for augmentative and alternative communication (FIATS-AAC-No) for use in Norway

Individuals who require augmentative and alternative communication (AAC) comprise a heterogeneous group, but all need follow-up to assure the appropriateness of implemented interventions. To enable this, outcome measures such as the Family Impact of Assistive Technology Scale for Augmentative and Alternative Communication (FIATS-AAC) may be used. However, instrument must be adapted to the language and culture in which they are to be used. The aim of the study was to therefore to explore the suitability of the Norwegian short-form version (FIATS-AAC-No) by investigating the reliability, validity, and perceived clinical usefulness. The study utilized a mixed-method design, including an online survey and two small group interviews. In total, 47 parents responded to the online survey. The online survey was comprised of three questionnaires, where FIATS-AAC-No was one of the questionnaires. Two group interviews, with two parents and two clinicians, were conducted. Findings show satisfactorily reliability, construct validity and content validity. The interviews revealed a need for specification of key concepts, that there are challenges involved in being parents of a child needing AAC, and that completing questionnaires was perceived as stressful by many parents. The clinicians viewed the FIATS-AAC-No as a potentially useful clinical tool and expressed that it brought to attention the need for follow-up parents have.
