Summary
A new hearing disability questionnaire (SDU) effectively measures speech perception difficulties. Form A is recommended for easier scoring, with interview administration being faster and more accessible than self-report.
Area of Science:
- Audiology
- Psychometrics
Context:
- Hearing impairment assessment requires reliable tools.
- Existing methods may lack efficiency or broad applicability.
Purpose:
- To develop and validate a multiple-choice questionnaire (SDU) for assessing hearing disabilities.
- To evaluate the SDU's psychometric properties, including factor structure, correlation with hearing thresholds, and administration modalities.
Summary:
- A 20-item questionnaire (SDU) was developed and tested on 123 adults with hearing impairment.
- Factor analysis identified a single factor related to speech perception in noise.
- The SDU total score correlated well with hearing thresholds (r = .74).
- Form A and B showed no significant differences in score or time, but Form A is preferred for computation.
- Interview administration was faster and more accessible than self-report.
Impact:
- The SDU is a valuable tool for hearing disability evaluation in aural rehabilitation.
- Its high applicability stems from short administration time, task simplicity, and flexible modality.
