Tinnitus Assessment: ICF Questionnaires for Hearing Health

No single tinnitus questionnaire captures the full impact of the condition on a person’s life, according to a new analysis. Researchers Alida Naudé and Amisha Kanji systematically compared the content of widely used assessment tools and found each one misses key aspects of daily function and environment. Their work, published in the Journal of Audiology and Otology, argues for a more strategic, evidence-based selection of questionnaires to guide truly person-centered care.

A Framework for Mapping the Full Impact of Tinnitus

Naudé and Kanji used the World Health Organization’s International Classification of Functioning, Disability and Health (ICF) as their analytical framework. The ICF provides a standardized language to describe health conditions, not just by the disease itself, but by how it affects body functions, daily activities, participation in society, and the influence of environmental and personal factors. By linking questionnaire items to specific ICF codes, the researchers could objectively compare what each tool measures and, importantly, what it leaves out.

Their methodology involved a rapid review to identify validated tinnitus questionnaires used in clinical practice. They then used established linking rules to map every item from tools like the Tinnitus Functional Index (TFI), Tinnitus Handicap Inventory (THI), Tinnitus Questionnaire (TQ), and the ICF-based international inventory for tinnitus (ICF-TINI) to corresponding ICF categories. This process allowed for a direct comparison of domain coverage across the entire set of tools.

The Incomplete Picture: Gaps in Current Assessment Tools

The analysis revealed that while popular tools like the TFI and THI are comprehensive in certain areas, they systematically overlook specific ICF domains. The ICF-TINI, designed with the framework in mind, addressed the widest range of domains but still did not achieve complete coverage.

A consistent shortcoming across nearly all questionnaires was the limited assessment of environmental factors. This ICF domain includes the physical, social, and attitudinal environment in which people live. For someone with tinnitus or hyperacusis, this could mean how their work acoustic environment exacerbates symptoms, or how family attitudes affect their coping. Most tools also provided insufficient detail on participation, which covers involvement in life situations like social gatherings, work, or family events.

“The findings underscore the importance of strategically combining tinnitus questionnaires based on ICF domain mapping, rather than relying solely on familiarity or tradition,” the authors wrote. This suggests clinicians may be missing critical information if they default to a single, familiar tool.

Practical Implications for Clinicians and Patients

For clinical practice, this research supports a shift from a one-size-fits-all assessment to a modular, person-centered approach. Instead of automatically reaching for the THI, an audiologist or therapist might first consider which ICF domains are most relevant to the individual sitting in front of them.

For a patient whose primary complaint is an inability to concentrate at work, selecting tools that robustly assess the “mental functions” and “work and employment” domains would be key. For another patient who reports social isolation, prioritizing questionnaires covering “community, social, and civic life” would be more appropriate. This method aligns with a broader movement in integrated auditory health, which considers the whole person, not just the auditory symptom.

This tailored assessment can directly inform treatment. A management plan for a patient struggling with environmental factors might include sound therapy and workplace modifications. A plan for someone with participation restrictions might focus more on cognitive behavioral therapy to address social anxiety, a technique also explored in process-based therapies for misophonia. The research creates a direct bridge from assessment to intervention.

A Call for Intentional Tool Selection and Future Research

The study, accessible via PMID 42338275 or DOI 10.7874/jao.2025.00346, does not declare any single questionnaire superior. Its value lies in providing a map. Clinicians can now see the specific strengths and blind spots of each tool, enabling them to combine questionnaires to fill gaps.

This approach mirrors advancements in other areas of health, where comprehensive assessment drives personalized care. For instance, in sleep medicine, understanding baseline factors is known to predict outcomes, as seen in research on CBT-I outcomes.

Naudé and Kanji note that further research is needed. The critical next question is whether using a combination of tools to achieve broader ICF coverage actually leads to better clinical outcomes, more satisfying patient-clinician interactions, and more effective, efficient treatment plans. By moving away from assessment by tradition and toward assessment by design, the field takes a significant step toward truly holistic care for tinnitus sufferers.
