The structure of Attachment Trauma: a Confirmatory Factor Analysis and Latent Profile Analysis on the Adult Attachment Trauma Questionnaire

The Adult Attachment Trauma Questionnaire (AATQ) is a newly developed measure to assessAttachment Trauma (AT) in adult romantic relationships. This study builds upon the study ofvalidation of the questionanire to further explore the structure and performance of the AATQ in anew general sample of 345 adults through a mixed data analysis strategy. A Confirmatory FactorAnalysis (CFA), an invariance analysis based on sex and a Latent Profile Analysis (LPA) ofsubscale scores were conducted. The CFA revealed that the best model was a six-factor structurenested within a higher-order factor representing general AT. Invariance testing demonstrated thatthe AATQ is robust across sex, showing configural, metric, and scalar invariance. The LPAidentified three latent classes of AT—High, Medium, and Low. Detailed discussions are providedon the performance of the subscales. In summary, the AATQ has proven to be a robust and stablequestionnaire.
