Objective : This study aimed to evaluate the validity and reliability of the Thai version of the Faces Test.
Material and Method: The Faces Test was administered to 60 participants, including 35 normal controls [mean age 37.2
(11.5) years and education 13.3 (4.2) years] and 25 patients with schizophrenia [mean age 37.2 (11.3) years and education
12.6 (3.9) years]. To study the convergent validity, the Faces Test was administered concurrently with the Thai version of the
Addenbrooke’s Cognitive Examination (ACE).
Results : The Faces Test had a correlation with the ACE (r = 0.65, p<0.001). The mean (SD) score on the Faces Test were 16.2
(1.7) for normal controls and 14.8 (2.1) for schizophrenia patients (p = 0.009). The Faces Test demonstrated excellent test-
retest reliability (intraclass correlation 0.85, p = 0.035) and acceptable internal consistency (0.62).
Conclusion : The Thai version of the Faces Test seem to be a valid and reliable measure to assess emotion recognition in Thai
people.
