Abstract
Adult cochlear implant candidates would self-report their executive functioning abilities as poorer than normal-hearing peers. These executive function abilities would correlate with laboratory-based cognitive tests. Lastly, executive functioning (EF) abilities would be associated with hearing-related quality of life. Executive function refers to cognitive abilities involved in behavioral regulation during goal-directed activity. Pediatric and adult users have demonstrated delays and deficits in executive function skills compared with normal-hearing peers. This study aimed to compare self-report executive function in adult cochlear implant candidates and normal-hearing peers and to relate executive function skills to laboratory-based cognitive testing and hearing-related quality of life. Twenty-four postlingually deaf adult cochlear implant candidates were enrolled, along with 42 normal-hearing age-matched peers. Participants completed self-reports of executive function using the Behavior Rating Inventory of Executive Function- Adult (BRIEF-A). Participants were also tested using laboratory-based cognitive measures, as well as assessment of hearing-related quality of life on the Nijmegen Cochlear Implant Questionnaire. Groups were compared on BRIEF-A scores, and relations between BRIEF-A and lab-based cognitive measures as well as Nijmegen Cochlear Implant Questionnaire scores were examined. Self-report executive function on the BRIEF-A was not significantly different between groups. Consistent relations of self-report executive function and nonverbal reasoning were identified. Strong relations were not found between self-report executive function and hearing-related quality of life. Executive function as measured by BRIEF-A demonstrates some relation with a laboratory-based metric of nonverbal reasoning, but not other cognitive measures. Hearing-impaired individuals did not report poorer EF than normal-hearing controls. EF additionally did not correlate with quality of life. Our findings provide preliminary, partial validation of the BRIEF-A instrument in the preoperative evaluation of adult cochlear implant candidates.
