Test-Retest Reliability of the Listening Self-Efficacy Questionnaire.
PURPOSE: The purpose of this study was to determine the test-retest reliability and the minimum detectable change (MDC) scores of the Listening Self-Efficacy Questionnaire (LSEQ). METHOD: A total of 77 older adults who were experienced hearing aid users were administered the LSEQ in pen-paper format on two separate occasions. They were provided the first copy of the LSEQ in the clinic to take home to complete. Those participants who completed and returned the first copy of the questionnaire were then mailed a second copy of the LSEQ to complete and return approximately 2 weeks later. The mean subscale and total scale scores from the two administrations were compared using intraclass correlation coefficients (ICCs) to determine test-retest reliability of the measure. The MDC scores, or the minimum difference between scores to demonstrate a real change in self-efficacy levels, were also calculated for each subscale and the total scale. RESULTS: The ICCs ranged from 0.786 to 0.920 for the subscale and total scale scores. The MDC scores for the subscale and total scale ranged from 14.3% to 19.1%. CONCLUSIONS: The results of this study indicate that the LSEQ has moderate to excellent test-retest reliability. The MDC scores demonstrate that the LSEQ has the potential to detect true changes in listening self-efficacy in older patients with hearing loss who use hearing aids. The LSEQ may aid clinicians in understanding listening self-efficacy in their patients and how their self-efficacy levels change with amplification.
