摘要

Background

The Adverse Childhood Experiences Abuse describes the physical, emotional, and sexual abuse undergone in childhood, which is associated with negative effects on mental, emotional, and relational health later in adulthood.

Objective

To assess the psychometric properties of the ACE-ASF (Adverse Childhood Experiences Abuse Short Form) in homosexual, and heterosexual in Ecuador, with a special focus on reliability, validity, measurement invariance, and network analysis of self-perceived abuse (fear, trapped and abused).

Methods

Instrumental study with 520 participants (nHomosexual = 260 and nHeterosexual = 260). The ACE-ASF was implemented along with confirmatory factor analysis, reliability, validity, and network analysis.

Results

The ACE-ASF offered excellent internal consistency (α = 0.845—0.883; ω = 0.856—0.876), convergent validity (AVE = 0.606—0.661), and discriminant validity (HTMT = 0.437). The two-factor model had ideal fit (CFI = 0.999; RMSEA = 0.000). Measurement invariance was verified across groups (ΔCFI ≤ 0.001). Network analysis showed differences by sexual orientation and abuse perception, highlighting the centrality of item A3 (betweenness = 1.67) and denser networks in lesbian (sparsity = 0.07) versus more fragmented networks in gay (sparsity = 0.67).

Conclusion

The ACE-ASF is a validated, reliable, invariant measure for sexual orientation and self-perceptions of abuse. Its use may help in the design targeted prevention and intervention methods to deal with the long-term consequences of childhood abuse for all relationship contexts.
