Trial Outcomes & Findings for A Simplified Patient-Centered Educational Tool for Improved Hearing-Aid Outcomes (NCT NCT01940705)

NCT ID: NCT01940705

Last Updated: 2019-02-21

Results Overview

Hearing Aid Skills and Knowledge measures knowledge and skills for tasks associated with hearing aid management, such as knowledge of and ability to change batteries, insert the hearing aid, etc. For knowledge scale, participant gives a verbal response. Items are assigned points: 0 (incorrect response) or 1 (correct response). For skills scale, participant conducts the required task. Items are assigned points: 0 (Could not perform task), 1 (Achieved with some difficulty, more than one attempt) or 2 (Achieved with no difficulty on first attempt). There were 15 knowledge items and 19 skill items. Percent correct was computed for each scale separately. Points were totaled, divided by the no. items with valid data, and multiplied by 100, with a correction to equate subscales. For the skills scale, percent correct scores were calculated based upon the notion that a value of 2 was considered 100% correct, 1 was considered 50% correct.
