Abstract
TARTARO, Gustavo Kastien; BAPTISTA, Makilim Nunes and PEIXOTO, Evandro Morais. Factorial Structure of the Brazilian Adult Attachment Scale (Ebrapeg-A 34). Psicol. teor. prat. [online]. 2024, vol.26, n.2, ePTPPA16123. Epub Dec 02, 2024. ISSN 1516-3687. https://doi.org/10.5935/1980-6906/eptppa16123.en.
Attachment begins in the early years of life and is linked to human development. The assessment of attachment requires the use of reliable instruments.
Objective:
to investigate the internal structure of the Brazilian Adult Attachment Scale. Internal structure was assessed through exploratory (EFA) and confirmatory (CFA) factor analysis with participants of both sexes from the general population (n = 808). The scale presented good fit indexes for four factors, explaining 48.89% of the variance (EFA / CFA: RMSEA = 0.0357 / RMSEA = 0.065; CFI = .925; TLI = .918 / CFI = .920; TLI = .914). The final version presented 34 items, and its factors demonstrated good reliability indexes: Secure α = .84; Fearful α = .88; Preoccupied α = .89; Dismissing α = .83. The EBRAPEG-A 34 constitutes a relevant tool for psychologists working in clinical and mental health contexts.
