CCCRC Olfactory Test Validation for the Brazilian Population

A validation study of the culturally adapted Connecticut olfactory test (CCCRC) involving 334 healthy volunteers aged over 18 years. The test-retest analysis was performed on 34 additional volunteers within four weeks. The research was conducted by Guilherme H.M. Fenólio and published as an Open Access paper.

Use Cases

• Establishing normative olfactory scores for the Brazilian population based on test results from 334 healthy volunteers.
• Evaluating test-retest reliability for olfactory assessment tools based on intraclass correlation coefficients reported for left and right nostrils.
• Investigating demographic factors in olfactory performance based on described differences in accuracy between genders and age groups over 60.
• Comparing cross-cultural olfactory test validations based on the adaptation of the CCCRC test methodology.

Strengths

• Validation involved a sample of 334 healthy volunteers, providing a basis for normative scores.
• Test-retest reliability was assessed on 34 volunteers, showing good to excellent agreement (ICC 0.65-0.77).
• The description provides specific statistical results, including p-values and percentile scores for performance analysis.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Data may reflect geographic and demographic bias inherent to the specific volunteer sample in Brazil.
