Abstract
Background
Unresolved/disorganized (U/d) attachment states of mind are associated with poor outcomes across numerous domains of functioning. However, the validity of existing self-report instruments measuring this construct remains questionable.
Objectives
The aim of the current study was to validate the DRS-8, an alternative version of the Disorganized Response Scale (DRS), by assessing its construct validity, internal consistency, and criterion validity with the U/d attachment scales on the Adult Attachment Interview (AAI).
Participants and setting
Date were collected from 222 expectant parents (78 % women) at T1 and from 67 of them at 12 months postpartum (T2).
Methods
Participants completed the DRS-8 and questionnaires assessing childhood trauma, romantic attachment, and psychological symptoms during pregnancy (T1). Seventy-four of them participated in the AAI at T1. At T2, parents completed a questionnaire assessing their infants' social-emotional development.
Results
The DRS-8 has two highly correlated dimensions, i.e., lapses in the monitoring of reasoning (four items) and discourse (four items). A confirmatory factor analysis supported a bifactor structure of the instrument, showing good fit indices and internal consistency (ω = 0.87). The DRS-8 was significantly correlated with U/d states of mind on the AAI, r(72) = 0.28, p = .016, and demonstrated excellent construct validity. Significant indirect effects of the DRS-8 were found in the associations between childhood trauma and psychological symptoms, and between parental trauma and infant social-emotional development.
Conclusions
The DRS-8 appears to be a promising self-report measure of U/d states of mind showing criterion validity with the AAI.
期刊介绍：
Official Publication of the International Society for Prevention of Child Abuse and Neglect. Child Abuse & Neglect The International Journal, provides an international, multidisciplinary forum on all aspects of child abuse and neglect, with special emphasis on prevention and treatment; the scope extends further to all those aspects of life which either favor or hinder child development. While contributions will primarily be from the fields of psychology, psychiatry, social work, medicine, nursing, law enforcement, legislature, education, and anthropology, the Journal encourages the concerned lay individual and child-oriented advocate organizations to contribute.
