Problem: Anomia is one of the most frequent manifestations in mild cognitive impairment and Alzheimer's disease (for a review, see Taler & Phillips, 2008), as well as in other neurodegenerative diseases (Macoir, Turgeon, & Laforce, 2015), traumatic brain injury (King, Hough, Walker, Rastatter, & Holbert, 2006), and post-stroke aphasia (Goodglass, 2001). In speech-language pathology, many tasks aim to specifically evaluate anomia, the most popular being picture naming. However, most existing tests are not culturally and linguistically adapted to French-speaking Quebecers, while those factors are known to influence performance (e.g., Sirois, Kremin, & Cohen, 2006; Yoon et al., 2004). Moreover, these tests do not control for the influence of important psycholinguistic parameters such as frequency and word length. The Test de dénomination de Québec-60 images (TDQ-60) was recently developed by our research team (Macoir, Beaudoin, Bluteau, Potvin, & Wilson, 2017) to overcome these limitations. However, the items selected for the TDQ-60 were all of high frequency and therefore, the test is not well suited for the assessment of mild anomia. Aims: The first objective of this study was to establish the convergent and discriminant validity of the Test de dénomination de Québec-30 images (TDQ-30), a test specifically developed for the assessment of mild anomia in the French-Quebec population. The second objective was to develop normative data for healthy, community-dwelling, French-speaking people of Quebec. Methods and procedures: Three groups of participants were assessed and compared to establish the convergent and discriminant validity of the TDQ-30: (1) a group of 14 individuals diagnosed with mild cognitive impairment (MCI), (2) a group of 10 individuals diagnosed with Alzheimer’s disease (AD) and, (3) a group of 30 healthy control participants. To establish convergent validity, in addition to the TDQ-30, the three groups of participants were administered the Boston naming test (Kaplan et al., 1983), another picture naming test for which a positive correlation with the TDQ-30 was expected. To assess discriminant validity, we tested whether the TDQ-30 score distinguished between the performance of healthy participants and the performance of individuals with MCI and AD. A total of 135 healthy community-dwelling adults, whose mother tongue and usual language was French, were recruited to establish normative data for the TDQ-30. Results: The results of the present study demonstrate that the TDQ-30 has good convergent validity and can distinguish between the performances of healthy participants on the one hand and participants with MCI and AD on the other hand, suggesting good discriminant validity. With respect to normative data, results showed that the total score on the test was significantly associated with age and education, but not with sex. Therefore, percentile ranges stratified by age and education were developed. Conclusion: This study provides normative data for the TDQ-30, a picture-naming test specifically designed to assess mild anomia. This more sensitive test will allow for earlier and more accurate detection of anomia, thus facilitating diagnosis and therapeutic intervention.
