ABSTRACT BACKGROUND: Exposure to traumatic events is a nonspecific risk factor for psychiatric symptoms including depression. The trauma-depression link finds support in numerous studies; however, explanatory mechanisms linking past trauma to current depressive symptoms are poorly understood. This study examines the role that attachment insecurity plays in mediating the relationship between prior exposure to trauma and current expression of depression severity. METHODS: Past trauma and attachment anxiety and avoidance were assessed at baseline in a large cohort (N=705) of adults admitted to a specialized adult psychiatric hospital with typical lengths of stay ranging from 6 to 8 weeks. Depression severity was assessed at day 14 of treatment using the Beck Depression Inventory-II. RESULTS: Interpersonal trauma (e.g., assaults, abuse) was correlated with depression severity, whereas exposure to impersonal trauma (e.g., natural disasters, accidents) was not. Adult attachment partially mediated the relationship between past interpersonal trauma and depression severity at day 14 among psychiatric inpatients. LIMITATIONS: Measure of trauma exposure did not systematically differentiate the age of exposure or relationship to the perpetrator. Individuals scoring high on the self-report attachment measure may be prone to over-report interpersonal traumas. CONCLUSIONS: Treatment of depression in traumatized patients should include an assessment of attachment insecurity and may be fruitful target for intervention.

    ABSTRACT: Background: The Difficulties in Emotion Regulation Scale (DERS: Gratz and Roemer, 2004) is a measure of emotion-regulation capacities with good construct validity, test-retest reliability and internal consistency. Factor analytic studies have produced mixed results, with the majority of studies supporting the original 6-factor model while several studies advance alternative 5-factor models, each of which raises questions about the psychometric validity of the Lack of Emotional Awareness factor. A limitation of prior psychometric studies on the DERS is the reliance on healthy subjects with minimal impairment in emotion regulation. The current study assesses the construct validity and latent factor structure of the DERS in a large sample of adult psychiatric inpatients with serious mental illness (SMI). Methods: Inpatients with SMI (N=592) completed the DERS, Acceptance and Action Questionnaire (AAQ-2), Patient Health Questionnaire (PHQSADS), and research diagnostic interviews (SCID I/II) at admission. Results: DERS total scores were correlated with AAQ-2 (r=.70), PHQ-Depression (r=.45), PHQ-Anxiety (r=.44) and moderately correlated with PHQ-Somatization (r=.28). Confirmatory factor analysis indicated that five and six-factor model produced equivalent fit indices. All factors demonstrated positive correlations with the exception of difficulty engaging in goal-directed behavior and lack of emotional awareness. Conclusions: The DERS is a strong measure with excellent internal consistency and good construct validity. Caution is warranted in discarding the six-factor model given the equivalence with the five-factor model, particularly in light of the body of clinical research evidence utilizing the full scale.

    ABSTRACT: Obsessive-compulsive personality disorder (OCPD) is characterized by traits such as extreme rigidity, perfectionism, and controlling behavior, all of which have a negative impact on interpersonal functioning. Attachment theory provides a useful framework to elucidate the interpersonal dysfunction characteristic of OCPD; yet, there is a dearth of attachment research on OCPD in the context of severe mental illness. Attachment security and personality disorders were assessed in adult inpatients with severe mental illness. Propensity Score Matching (PSM) was used to match OCPD and control subjects on age, gender, number of psychiatric disorders, and number of criteria endorsed for borderline personality disorder. Consistent with hypotheses, the OCPD group (n=61) showed greater attachment avoidance than controls (n=61), and the avoidance was manifested in a predominance of the most insecure attachment style, fearful attachment. Correlations between attachment anxiety/avoidance with specific OCPD diagnostic criteria revealed that attachment avoidance was correlated with four of eight OCPD criteria across the full sample. Within the subset of OCPD patients, attachment avoidance was significantly correlated with OCPD criterion 3 (is excessively devoted to work and productivity to the exclusion of leisure activities and friendships). The use of self-report measure of attachment and the high burden of illness in the SMI population may not generalize to interview based assessment or outpatients, respectively. Findings attest to the severity of impairment in interpersonal functioning and attachment avoidance, in particular, is characteristic of OCPD patients. These results suggest that viable treatment targets include interpersonal functioning along with more classical features of OCPD such as perfectionism and obsessiveness in task performance.
