Psychometric Validation of the Adult Attachment Scale: an Examination of Collegiate Emerging Adults with and Without Adverse Childhood Experiences
摘要
The present study examined the psychometric properties of the Adult Attachment Scale (AAS) in a sample of 307 collegiate emerging adults, aged 18–29, recruited from a local university. Participants were assessed for attachment style, adverse childhood experiences (ACEs), depression, and anxiety, utilizing the AAS, ACEs Scale, CES-D, and GAD-7, respectively. Exploratory factor analysis (EFA) indicated a four-factor structure, while confirmatory factor analysis (CFA) demonstrated that a two-factor model, representing attachment anxiety and avoidance, provided the best model fit (CMIN/DF = 1.559; TLI = 0.985; CFI = 0.993; RMSEA = 0.044). Internal consistency was excellent for the attachment anxiety subscale (α = 0.90) and acceptable for the attachment avoidance subscale (α = 0.74). Bivariate correlations supported convergent validity, with attachment anxiety showing moderate associations with ACEs (r =.31), depression (r =.58), and anxiety (r =.51). Independent sample t-tests revealed that participants with four or more ACEs, as well as those meeting clinical cut-offs for depression and anxiety, reported significantly higher attachment anxiety and avoidance. These results suggest that the AAS is a reliable and valid measure of attachment in emerging adults that is sensitive to variations in ACEs, depression, and anxiety, making it a useful tool for further research on attachment patterns in this population.
