Complex posttraumatic stress disorder in women from a psychometric perspective

Area of Science:

• Psychiatry
• Psychology
• Trauma Studies

Background:

• Complex Post-Traumatic Stress Disorder (CSTD) formulation by Herman (1992a) was not integrated into the DSM-IV.
• This formulation, however, shows significant relevance in personality assessments of women undergoing inpatient treatment for trauma-related disorders.

Purpose of the Study:

• To investigate the relationship between personality assessment scores and attachment styles in women with trauma-related disorders.
• To examine the validity of Herman's complex PTSD formulation using psychometric data.
• To explore patterns of relationship disturbance associated with childhood abuse and neglect.

Main Methods:

• Utilized the Millon Clinical Multiaxial Inventory-III (MCMI-III) for personality assessment.
• Employed the Adult Attachment Scale (AAS) to measure attachment styles.
• Administered the Childhood Trauma Questionnaire (CTQ) as a self-report measure of childhood abuse and neglect.
• Analyzed data from women in inpatient treatment for trauma-related disorders.

Main Results:

• Data confirmed Herman's complex PTSD formulation.
• Two primary facets of relationship disturbance were identified: enmeshment in ambivalence and profound isolation.
• Enmeshment was associated with depressive, dependent, and self-defeating personality traits, alongside ambivalent attachment.
• Isolation was linked to avoidant and schizoid personality traits, coupled with profoundly insecure attachment.

Conclusions:

• Psychometric findings support Herman's complex PTSD formulation in a clinical population.
• The study highlights distinct patterns of relationship disturbance (enmeshment and isolation) in women with trauma histories.
• A model is proposed for integrating these psychometric findings into patient education and diagnostic processes for trauma-related disorders.
