Objective:To examine the reliability and validity of the Chinese version of individuation test for emerging adults short version (ITEAS) among college students.Methods:A total of 1 778 college students were investigated with the Chinese version of the ITEAS, the separation-individuation test of adolescence subscales, including the separation anxiety subscale and dependency denial subscale, and the Rosenberg self-esteem scale from August to October 2021.Ninety of these college students were retested with the Chinese version of the ITEAS after a 4-week interval.And data were analyzed by SPSS 26.0 and AMOS 21.0.Results:Exploratory factor analysis found that both the revised ITEAS for fathers (ITEAS-F) and ITEAS for mothers (ITEAS-M) had 21 items in five dimensions, including seeking support, connection, invasion, self-reliance and fear of disappointing the parents.Confirmatory factor analysis revealed that the five-factor models for both the ITEAS-F and ITEAS-M scales fit well ( χ2/ df=2.27, CFI=0.92, TLI=0.90, RMSEA=0.06, SRMR=0.07; χ2/ df=2.38, CFI=0.94, TLI=0.93, RMSEA=0.06, SRMR=0.07). The criterion-related validation showed that the dimensions of seeking support, connection, and self-reliance in both the ITEAS-F and ITEAS-M were significantly negatively correlated with separation anxiety and rejection of reliance, and were significantly positively correlated with self-esteem.Moreover, the dimensions of invasion and fear of disappointing the parents were significantly positively correlated with separation anxiety and rejection of reliance, and were significantly negatively correlated with self-esteem.Furthermore, the Cronbach’s α ranged from 0.79 to 0.90 ( P<0.01) and 0.82 to 0.92 ( P<0.01), respectively.And the retest reliability ranged from 0.73 to 0.86 ( P<0.01) and 0.78 to 0.86 ( P<0.01), respectively. Conclusion:The Chinese version of ITEAS meets the requirements for psychometric assessments and is a valid and reliable instrument.
