Characteristics of the quick repeat-recall test (Q-RRT)

Area of Science:

• Audiology
• Cognitive Psychology
• Speech-Language Pathology

Background:

• Assessing speech-in-noise (SPIN) ability is crucial for understanding auditory challenges.
• Existing tests may not fully capture the multifaceted nature of SPIN perception, including cognitive load and effort.

Purpose of the Study:

• To evaluate the reliability and validity of the Quick Repeat-Recall Test (Q-RRT).
• To determine if the Q-RRT can accurately measure speech-in-noise ability, working memory, listening effort, and noise acceptance.

Main Methods:

• A within-subject repeated measures design was employed.
• Participants completed the Q-RRT and full-RRT under varying noise conditions and signal-to-noise ratios (SNRs).
• Test-retest reliability was assessed over 1-3 weeks, alongside external validation using measures of SPIN ability (HINT), memory (DST-F, RST), and noise tolerance (TNT).

Main Results:

• Q-RRT repeat and recall scores were comparable to the full-RRT.
• Listening effort and tolerable time ratings were better with the Q-RRT.
• Repeat scores correlated with HINT, recall scores with DST-F and RST, and tolerable time with TNT.
• Intraclass correlation coefficients for test-retest reliability ranged from fair to excellent (0.41-0.91).

Conclusions:

• The Q-RRT is a dependable and accurate measure for assessing speech-in-noise, working memory, listening effort, and noise acceptance.
• The Q-RRT offers a valid and reliable alternative for evaluating complex auditory processing in noisy environments.
