Overview

Validation study demonstrates acceptable discriminative ability and reliability for the Japanese MASC in adults with autism, supporting its clinical utility for assessing social cognition.

Key Points

  • To develop a Japanese version of the Movie for the Assessment of Social Cognition (MASC-J) and conduct an initial evaluation of its reliability and validity in adults with autism spectrum disorder compared with healthy controls.
  • Enrolled 30 adults with autism spectrum disorder and 30 healthy controls who completed the MASC-J, Reading the Mind in the Eyes Test, Autism-Spectrum Quotient, and Japanese Adult Reading Test.
  • Evaluated internal consistency, test-retest reliability, partial convergent validity, and discriminative performance via receiver operating characteristic analysis.
  • MASC-J scores were significantly lower in the autism spectrum disorder group than in healthy controls, with an area under the curve of 0.804.
  • The tool demonstrated acceptable internal consistency, excellent test-retest reliability, and a significant positive association with estimated full-scale IQ in the autism group.
  • Participants with autism spectrum disorder showed significantly more overmentalizing and absence-of-mentalizing errors than controls, while undermentalizing errors showed no group difference.
