Reliability and validity of the Chinese version of the Comprehensive Autistic Trait Inventory-short form (CATI-SF-C) in the general population

Reliability and validity of a novel mobile-based automatic battery of cognitive tests in healthy young Chinese adults

PURPOSE

To evaluate the reliability and validity of a newly developed computerized Automated Battery of Cognitive Tests in healthy individuals without cognitive impairments or psychiatric disorders.

METHODS

From April 20 to July 1, 2023, 142 healthy individuals in Beijing and Tangshan, China were assessed using the Automated Battery of Cognitive Tests. After a 3-week interval, 36 participants were randomly selected for retesting. The assessment also included administration of the Repeatable Battery for the Assessment of Neuropsychological Status and the Automated Battery of Cognitive Tests to 59 participants.

RESULTS

The Automated Battery of Cognitive Tests consists of 16 subtests. Internal consistency reliability was 0.75. The test-retest reliability for each factor ranged from 0.337 to 0.850 (p < 0.05). The criterion-related validity, as measured by correlation with the total Repeatable Battery for the Assessment of Neuropsychological Status score, was 0.748 (p < 0.001). The cumulative variance contribution rate is 70.109%. The results of the confirmatory factor analysis indicated a good model fit.

CONCLUSIONS

The computerized Automated Battery of Cognitive Tests is a cognitive self-assessment tool with good reliability and validity. It can evaluate multiple aspects of cognitive performance in healthy individuals and is suitable for self-administration through remote access via Internet.

Evaluation of the psychometric indicators of the Comprehensive Autistic Trait Inventory in Iranian adults

BACKGROUND

The DSM-5's Comprehensive Autism Traits Inventory (CATI) was a useful diagnostic tool for the general population because it covered all the critical aspects of autism. However, its reliability and validity in the overall Iranian population still need to be investigated.

PURPOSE

We reviewed the inventory and estimated the validity and reliability of the Iranian version of CATI among 1800 adults.

METHODS

The Persian version of CATI (CATI-I) was administered to 1800 Iranian adults using the online Star Questionnaire system. Internal consistency, convergent validity, discriminant validity, test-retest reliability, and measurement invariance across genders were calculated.

RESULTS

The Correlated social & non-social bifactor model showed the best fit in the Iranian community (CFI=.966; TLI=.947; RMSEA=.045; SRMR=.028). Ultimately, the CATI-I scale in the Iranian community consisted of 39 items across six factors and two higher-order constructs. Additionally, the CATI-I scale's convergent validity and reliability values were acceptable.

CONCLUSION

The CATI-I demonstrates satisfactory reliability and validity in measuring autism traits. It is an appropriate model for the second-order social and non-social factors, and it also shows measurement invariance across genders.

The Chinese "Reading the Mind in the Eyes" Test: A study with normal adults, and adults with Asperger syndrome/high-functioning autism

We developed a 28-item Chinese Eyes Test and tested its psychometric properties with a mixed sample of high-functioning adults with autism or Asperger syndrome and neurotypical adults. The Chinese Eyes Test showed good convergent and divergent validity, satisfactory known-group discrimination, and acceptable internal consistency. The identified cutoff score of 18 or below (Sensitivity: 66.7%; Specificity: 84.0%) should be useful for identifying clinically significant levels of social cognitive deficits, in terms of difficulty with the perceptual understanding of others' mental states, in high-functioning adults with autism or Asperger syndrome.
