Development of the English Listening and Reading Computerized Revised Token Test Into Cantonese: Validity, Reliability, and Sensitivity/Specificity in People With Aphasia and Healthy Controls.
Journal of speech language and hearing research : JSLHR, 2020Co-Authors: Mehdi Bakhtiar, Min Ney Wong, Emily Ka Yin Tsui, Malcolm R. McneilAbstract:Purpose This study reports the psychometric development of the Cantonese versions of the English Computerized Revised Token Test (CRTT) for persons with aphasia (PWAs) and healthy controls (HCs). Method The English CRTT was translated into standard Chinese for the Reading-Word Fade version (CRTT-R-WF-Cantonese) and into formal Cantonese for the Listening version (CRTT-L-Cantonese). Thirty-two adult native Cantonese PWAs and 42 HCs were Tested on both versions of CRTT-Cantonese Tests and on the Cantonese Aphasia Battery to measure the construct and concurrent validity of CRTT-Cantonese Tests. The HCs were reTested on both versions of the CRTT-Cantonese Tests, whereas the PWAs were randomly assigned for reTesting on either version to measure the Test-reTest reliability. Results A two-way, Group × Modality, repeated-measures analysis of variance revealed significantly lower scores for the PWA group than the HC group for both reading and listening. Other comparisons were not significant. A high and significant correlation was found between the CRTT-R-WF-Cantonese and the CRTT-L-Cantonese in PWAs, and 87% of the PWAs showed nonsignificantly different performance across the CRTT-Cantonese Tests based on the Revised Standardized Difference Test. The CRTT-R-WF-Cantonese provided better aphasia diagnostic sensitivity (100%) and specificity (83.30%) values than the CRTT-L-Cantonese. Pearson correlation coefficients revealed significant moderate correlations between the Cantonese Aphasia Battery scores and the CRTT-Cantonese Tests in PWAs, supporting adequate concurrent validity. Intraclass correlation coefficient showed high Test-reTest reliability (between .82 and .96, p < .001) for both CRTT-Cantonese Tests for both groups. Conclusions Results support that the validly translated CRTT-R-WF-Cantonese and CRTT-L-Cantonese Tests significantly differentiate the reading and listening comprehension of PWAs from HCs and provides acceptable concurrent validity and high Test-reTest reliability for both Tests. Furthermore, favorable PWA versus HC sensitivity and specificity cutoff scores are presented for both CRTT-Cantonese listening and reading Tests.

An Item Response Theory analysis of the Revised Token Test in normally developing native Spanish speaking children
Anuario de Psicología, 2015Co-Authors: Maria Quintana, Geisa Gallardo, Isabel Salinas González, Malcolm R. McneilAbstract:Revised Token Test (RTT) is a proven sensitivity Test for the evaluation of language comprehension. There is little evidence regarding the psychometric properties of the same in children. Similarly, many facts about the facilities of the item response theory (IRT) will not contribute to study these properties in neuropsychological Tests and even less when applied to these populations.Thus, the objectives were to assess the psychometric properties of the RTT Test population of children with normal development and also show the utility of the IRT models type of neuropsychological assessments. The sample consisted of a total of 250 healthy spanish-speaking children from 4 to 12 years old living in the city of Guadalajara (Mexico). This sample was divided into two groups,the older younger children (4-9 years) and (10 to 12 years). The results suggest high sensitivity of the RTT sample at different ages and also an excellent discriminant validity in both groups. In addition, the Test allowed to properly classify different levels of skills related to language and other latent traits.

Translating and validating a Mandarin Chinese version of the computerized revised Token Test
Speech Language and Hearing, 2013Co-Authors: Szu-han Kay Chen, Malcolm R. Mcneil, Katya Hill, Sheila R. PrattAbstract:The primary objective of this study was to validate the item translation of the Computerized Revised Token Test-Mandarin (CRTT-Mandarin) and to investigate the concurrent validity of this translation in normal control participants (NP) and in persons with aphasia (PWA). The translation of the Computerized Revised Token Test into CRTT-Mandarin was accomplished by forward and backward translation procedures. The concurrent validity was evaluated by comparing the performance of NP and PWA on CRTT-Mandarin and on the Concise Chinese Aphasia Test (CCAT; Chung, Li and Chang, 2003); the single standardized Mandarin Chinese aphasia Test. Eleven PWA and 19 NP who were native Chinese speakers served as participants. All the participants were administered both aphasia Tests. Tests of difference between groups and Tests of association were computed between the CRTT-Mandarin overall and between subTest scores and each of the CCAT subTests and overall score. A high degree of agreement was achieved between the forward a...

Psychometric data for the revised Token Test in normally developing Mexican children ages 4-12 years.
Archives of clinical neuropsychology : the official journal of the National Academy of Neuropsychologists, 2011Co-Authors: Geisa Gallardo, Joan Guàrdia, Teresita Villaseñor, Malcolm R. McneilAbstract:Language comprehension is vital to social and educational development but few pediatric Tests are available for its assessment. To approach this problem, two versions of the Token Test (TT), "TT short form" (DeRenzi & Faglioni, 1978) and "Revised Token Test" (RTT), were first compared. Using a sample of 88 normally developing Spanish-speaking children, the Tests were compared on their: (a) established psychometric development and (b) internal consistency. The RTT was judged to be superior and was selected for additional experimentation. The RTT was compared with a developmental measure of lexical knowledge on a cross-sectional sample of 250 4-12-year-old normally developing Spanish-speaking children. A significant positive and high correlation supports its concurrent validity. Significant differences across the age groups, along with a principal component analysis that yielded a three-factor structure, support its construct validity. Preliminary normative data across the nine age groups are provided.

Effects of linguistic complexity and executive attentional demands on sentence comprehension in persons with aphasia and normal controls: Exploring on-line and offline measures with two reading versions of the Computerized Revised Token Test
2011Co-Authors: Malcolm R. Mcneil, Sheila R. Pratt, Neil Szuminsky, Aelee Kim, Wiltrud Fassbinder, Michael Walsh Dickey, Diane L. Kendall, Kyuong Yeul Lim, Rebecca Hunting Pompon, Donald KriegerAbstract:Verbal Working Memory (VWM) specifies the fundamental cognitive components (language computations (LC), short term memory, executive attention (EA)) for sentence comprehension. Tests for VWM do not assess their differential impairments. The Computerized Revised Token Test (Reading) (CRTT-R) was administered in normal reading and “Stroop” conditions to controls and persons with aphasia (PWA). CRTT-R captured the LC and EA components of VWM in both groups. On-line color word reading times and errors captured the EA effects. Off-line CRTT-R scores, reading and response times captured the LC effects. Response time yielded the expected PWA by EA and PWA by LC complexity interactions.

A comparison of left versus right hand, and mouse versus touchscreen access methods on the Computerized Revised Token Test
2009Co-Authors: Malcolm R. Mcneil, Sheila R. Pratt, Jee Eun Sung, Neil Szuminsky, Aelee Kim, Pat DoyleAbstract:This study examined the effect of hand used to access mouse vs. touchscreen in both normal adult individuals (NAI) and persons with aphasia (PWA) on the overall score from the Computerized Revised Token Test (CRTT) (McNeil et al., 2008). Both access modes were highly correlated with each other in both groups. PWA performed significantly worse than the NAI on both access modes, regardless of hand used. The touchscreen access mode generated significantly higher scores than the mouse for both groups independent of hand. The correlation coefficients within hand and between access modes were significant and high for both groups.

response time measurements in the ios app based Token Test the brief Token Test in the elderly
Geriatrics & Gerontology International, 2014Co-Authors: Hyanghee Kim, Jee Eun Sung, Jungwan Kim, Eun Jeong Park, Ji Hye Yoon, Hyun Ji Yoo, Soo Ryon KimAbstract:Aim A pen and paper Token Test utilizing binary scoring of accuracy–inaccuracy in responses evaluates linguistic functions including verbal comprehension. However, the Test might not be sensitive enough to detect the aging effect on performance in normal older adults unless the Test utilizes a multidimensional scoring system. We hypothesized that the measurement of response time (RT) instead of accuracy would be a feasible way to measure deterioration of verbal comprehension as a function of age in this linguistically vulnerable population. Methods Data were acquired from 174 community-dwelling normal older adults (147 females and 27 males, mean age 75.9 ± 6.13 years, range 65–94 years). In order to automatically quantify accuracies and RT, we developed an iOS app-based Token Test, comprising of four subTests (24 items, 6 items in each subTest), and administered it to each participant. Results RT of the second, third and fourth subTests (P < 0.001, P < 0.01, P < 0.05, respectively) and the average RT across all four subTests (P < 0.01) had significant partial correlation coefficients with age. The results of the multiple linear regression analyses showed that the models for RT and average RT analyses of the three subTests (2, 3 and 4) included the age variable. Conclusion RT measurement of the iOS app-based Token Test could be highly useful and convenient to better detect abnormalities in linguistic efficiency. RT measurement in the Token Test could be used as a screening tool for linguistic slowing in the elderly population. Geriatr Gerontol Int 2013; 14: 969–974.

The Computerized Revised Token Test: Assessing the Impact of Age and Sound Intensity
2006Co-Authors: Sheila R. Pratt, Malcolm R. Mcneil, Cynthia Eberwein, Tepanta R. D. Fossett, Neil Szuminsky, Amanda Ortmann, Jillyn Roxberg, John D. Durrant, Patrick J. DoyleAbstract:The Revised Token Test (McNeil & Prescott, 1978, RTT) is a well-established Test of auditory language processing disorders in persons with aphasia. A computerized version of the Test, the Computerized Revised Token Test (C-RTT), was developed recently in our laboratory to better control stimuli presentation, and eliminate variability associated with the complex scoring requirements of the RTT. In the current study the impact of participant age and acoustic signal intensity on performance of non-brain injured adults on the C-RTT was assessed. Although age effects have not observed with the RTT, we believed that strict adherence to timing and stimuli characteristics allowed by computer administration and scoring could separate young from older adults.
