Abstract:
The Adult Attachment Trauma Questionnaire (AATQ) is a newly developed measure to assess Attachment Trauma (AT) in adult romantic relationships. The current study builds upon the original validation study to further explore the psychometric properties of the AATQ in a general sample of 345 adults, using both variable-centered (Confirmatory Factor Analysis; CFA) and person-centered (Latent Profile Analysis; LPA) data analyses. The CFA revealed that the best model was a six-factor structure with a higher-order factor representing general AT. Invariance testing demonstrated that the AATQ is robust across sex, showing configural, metric, scalar, and strict invariance. The LPA identified three latent classes of AT (i.e. High, Medium, and Low). Discussions are provided on the correlates of the subscales. In summary, the AATQ has proven to possess robust psychometric properties.
