Objective: Individuals who are deaf or hard of hearing (DHH) may find adherence to their hearing devices difficult due to internal experiences related to their hearing loss such as sadness or frustration. The Acceptance and Action Questionnaire-Adult Hearing Loss (AAQ-AHL) is the only measure available to assess psychological inflexibility as it relates to hearing loss. The purpose of this study was to confirm the single latent structure of the AAQ-AHL (through confirmatory factory analysis) and test convergent and discriminant validity.
Design: Cross-sectional data was used to further validate the AAQ-AHL.
Study sample: Participants were 146 adults who had diagnosed hearing loss and used a hearing aid.
Results: Results revealed the AAQ-AHL has a single latent structure, correlated to other similar constructs (psychological flexibility and hearing aid efficacy), and not correlated to unrelated constructs (hearing loss severity). These results suggest that the AAQ-AHL is a valid instrument to assess psychological flexibility as it relates to hearing aid use.
Conclusion: Together, the findings imply the AAQ-AHL has strong psychometric properties and justification to use in a clinical setting.
