Middle childhood is the least understood developmental period in the attachment literature, likely due to active reorganization of the attachment system during this stage. Coinciding with increased cognitive and socioemotional competencies, middle childhood attachment begins to transition from relationship-specific attachment to general attachment representations. While parents continue serving as the primary attachment figure used as a secure base and safe haven, noticeable shifts occur in terms of the need for availability over proximity to attachment figures and the child's involvement in maintaining the attachment relationship. Currently, there is no dominant conceptual or methodological approach for studying attachment in middle childhood. The present study sought to develop and validate an observational coding system examining middle childhood attachment using a dimensional approach. The Middle Childhood Behavioral Attachment Dimensions (MCBAD) system demonstrated mixed reliability and validity compared to other established attachment measures. Compared to traditional categorical attachment measures, this study provides evidence for the utility of an anxiety-avoidance dimensional attachment scale in childhood. Additionally, the MCBAD is the first observational system that examines both nonverbal and verbal attachment behaviors in an unstructured separation-reunion episode, and findings suggest a need for further examination of verbal attachment during this developmental stage.

The work group in charge of editing the trauma disorders in the upcoming edition of the International Classification of Diseases (ICD-11) made several changes to the trauma criteria. Specifically, they simplified the criteria for posttraumatic stress disorder (PTSD) and added a new trauma disorder called complex PTSD (CPTSD). To assess the new and newly defined trauma disorders, Litvin, Kaminski and Riggs developed a self-report trauma measure called the Complex Trauma Inventory (CTI). Although the reliability and validity of the CTI has been supported, no empirically-derived cutoff scores exist. We determined the optimal CTI cutoff scores using receiver operating characteristic (ROC) analyses in a diverse sample of 82 participants who experienced trauma and were recruited from an inpatient trauma unit, student veteran organizations, and university classrooms. We used the Clinician-Administered Interview for Trauma Disorders (CAIT) to diagnose the presence of an ICD-11 trauma disorder, and we correlated the results of the CAIT with the Clinician-Administered PTSD Scale for the DSM-5 to establish the convergent validity of the CAIT, r = .945, p < .001. For the ROC analyses, the CTI was used as the index test and the CAIT was used as the criterion test. The area under the curve (AUC) …
