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.
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).
Date were collected from 222 expectant parents (78 % women) at T1 and from 67 of them at 12 months postpartum (T2).
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.
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.
The DRS-8 appears to be a promising self-report measure of U/d states of mind showing criterion validity with the AAI.
未解决/混乱（U/d）的依恋状态与多个功能领域的不良结果有关。然而，现有的衡量这一结构的自我报告工具的有效性仍然值得怀疑。
本研究的目的是通过评估其结构效度、内部一致性和与成人依恋访谈（AAI）上的 U/d 依恋量表的效标效度，来验证 DRS-8，即混乱反应量表（DRS）的替代版本。
数据来自 222 名准父母（78%为女性），他们在 T1 时完成了 DRS-8 以及评估儿童创伤、浪漫依恋和怀孕期间心理症状的问卷，其中 67 名在产后 12 个月（T2）时完成了问卷。74 名参与者在 T1 时参加了 AAI。在 T2 时，父母完成了一份评估他们婴儿社会情感发展的问卷。
DRS-8 有两个高度相关的维度，即推理监测的失误（四个项目）和话语（四个项目）。验证性因素分析支持该工具的双因素结构，具有良好的拟合指数和内部一致性（ω=0.87）。DRS-8 与 AAI 上的 U/d 状态的心理显著相关，r（72）=0.28，p=0.016，具有良好的结构效度。DRS-8 在儿童创伤与心理症状之间以及父母创伤与婴儿社会情感发展之间的关系中存在显著的间接效应。
DRS-8 似乎是一种有前途的 U/d 状态心理的自我报告衡量工具，与 AAI 具有效标效度。
