The current study aimed to evaluate the potentially traumatic aspects of psychotic symptoms and psychiatric treatment of psychosis using qualitative methods. Participants included 63 people with first episode psychosis or multiple psychotic episodes recruited from an inpatient psychiatric unit and an urban state psychiatric hospital in the North East region of the United States. Quasi-structured interviews were used to explore those aspects of symptoms and treatment that were perceived as traumatic Emotional reactions to the most traumatic aspect of symptoms and treatment, during and after the event, were also examined. Participants described a number of traumatogenic aspects of psychotic symptoms, …

Impact Of Cannabis Use On Treatment Outcomes Among Adults Receiving Cognitive-Behavioral Treatment For Ptsd And Substance Use Disorders, Lesia M. Ruglass, Alina Shevorykin, Vanja Radoncic, Kathryn M. Z. Smith, Philip H. Smith, Isaac R. Galatzer-Levy, Santiago Papini, Denise A. Hien

Publications and Research

Background: Research has demonstrated a strong link between trauma, posttraumatic stress disorder (PTSD) and substance use disorders (SUDs) in general and cannabis use disorders in particular. Yet, few studies have examined the impact of cannabis use on treatment outcomes for individuals with co-occurring PTSD and SUDs. Methods: Participants were 136 individuals who received cognitive-behavioral therapies for co-occurring PTSD and SUD. Multivariate regressions were utilized to examine the associations between baseline cannabis use and end-of-treatment outcomes. Multilevel linear growth models were fit to the data to examine the cross-lagged associations between weekly cannabis use and weekly PTSD symptom severity and primary …

Persistent Amygdala Novelty Response Is Associated With Less Anterior Cingulum Integrity In Trauma-Exposed Women, Seungyeon A. Yoon, Mariann R. Weierich

Publications and Research

Objectives: We investigated the potential role of cingulum and uncinate fasciculus integrity in trauma-related neural hypervigilance, indexed by less discrimination between amygdala activation to novel and familiar affective images.

Participants: 22 women (mean age 21.7 ± 3.9 years) with a history of trauma, and 20 no-trauma controls (mean age 21.9 ± 4.8 years).

Measures: Trauma exposure and trauma-related symptoms were assessed during structured clinical interview. White matter integrity in the anterior cingulum, parahippocampal cingulum, and uncinate fasciculus was measured using diffusion weighted imaging. Amygdala response to novel and familiar affective scenes was measured with functional magnetic resonance imaging.

Results: Trauma-exposed …
