Validity and reliability of the Chinese version of adult disorganized attachment scale in Chinese adults

Disorganized attachment is a predictor of psychopathology. Given that no scale has been developed in China that can detect disorganized attachment and help prevent related psychological disorders, this study aimed to translate and examine the validity and reliability of the Chinese version of Adult Disorganized Attachment Scale (ADAS). The sample consisted of 345 Chinese adult residents (as sample 1), 356 Chinese university students (as sample 2; M-age = 19.72, SDage = 1.32), and 109 Chinese university students selected from sample 2 (as test-retest sample). Results of exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) suggested that the one-factor model of ADAS fit well. Furthermore, the criterion validity of ADAS validity was good. Specifically, ADAS was significantly related to Experiences in the Close Relationship Scale-Relationship Structures Questionnaire, Depression Anxiety Stress Scale-21, Buss-Perry Aggression Scale, and the Satisfaction with Life Scale. The internal consistency reliability and retest reliability of ADAS was good. Thus, the Chinese version of the 9-item ADAS is a reliable and effective tool, which may promote the studies and interventions of adult disorganized attachment in China. This study is the first to investigate the characteristics of disorganized attachment in Chinese adults, thus expanding the cross-cultural exploration of adult disorganized attachment. Limitations and future directions are discussed.
