Résumé

Background: A review of the scientific literature showed few valid tools for assessing reactive attachment disorder (RAD) and disinhibited social engagement disorder (DSED), two diagnostic entities traditionally grouped under « attachment disorders. » The Early TRAuma-related Disorders Questionnaire (ETRADQ), a caregiver report, was developed to assess attachment disorders in school-age children based on the Diagnostic and Statistical Manual of Mental Disorders-Fifth edition criteria. This study sought to validate this instrument.

Method: Caregivers of school-age children from the community (n = 578) and caregivers of at-risk children adopted or in out-of-home care (n = 245) completed a sociodemographic questionnaire, the ETRADQ, the Relationship Problem Questionnaire, the RADA (RAD and DSED Assessment) interview, and the Barkley Functional Impairment Scale for Children and Adolescents.

Results: Confirmatory factor analysis of the ETRADQ items supported the expected organization of the measure, that is, two second-order factors and five subfactors: (1) RAD scale (three subscales: Low selective attachment, Low social and emotional responsiveness, Emotional unpredictability) and (2) DSED scale (two subscales: Interactions with unfamiliar adults, Social disinhibition). All scales showed excellent internal consistency, test-retest reliability, convergent validity, and known-group validity.

Conclusions: Results support the reliability and validity of the ETRADQ.
