Introduction/UNASSIGNED:Group Skills Training in Affective and Interpersonal Regulation (STAIR) is an evidence-based, manualized treatment for individuals with post-traumatic stress symptoms, that focuses on improving functioning through mood management (e.g., emotion regulation) and relationship skills development. To date, no study has evaluated the potential benefit of group STAIR among Veterans. Feasibility of delivering STAIR in a mixed-gender group format and the potential impact of gender on outcome were examined. Materials and Methods/UNASSIGNED:Participants (n = 39) were Veterans enrolled in a post-traumatic stress disorder (PTSD) Clinic at a large VA Medical Center. Veterans participated in one of four mixed-gender STAIR groups and completed self-report questionnaires of PTSD symptoms and general psychological distress at pre-treatment and post-treatment. Institutional review board approval was obtained for this study. Results/UNASSIGNED:There was significant pre-treatment to post-treatment improvements in PTSD symptoms as measured by the Post-traumatic Stress Checklist (PCL) (Cohen's d = 0.91), as well as in general psychological distress as measured by the Brief Symptom Inventory (BSI) (Cohen's d = 0.90). Change in PTSD symptoms from pre-treatment to post-treatment did not differ across gender. However, the interaction between gender and time on change in (BSI) was significant, where change in general psychological distress significantly decreased from pre-treatment to post-treatment for male Veterans but not for female Veterans. Conclusion/UNASSIGNED:The results from this study demonstrate the feasibility and initial effectiveness of STAIR delivered in a mixed-gender group format for Veterans with PTSD. It should be noted, however, that male Veterans benefited more from this approach than female Veterans. The findings suggest the value of investigating Veterans' attitudes and beliefs about the benefits and drawbacks of mixed-gender group therapy for trauma-related difficulties.

OBJECTIVE:Adverse Childhood Experiences (ACEs) have consistently been associated with a range of negative psychological and physical outcomes in adulthood. Despite the strength of this association, no studies to date have investigated psychological processes that might underlie this relationship. The current study evaluated emotion regulation as a potential mediator between ACEs and three outcomes: PTSD symptoms, depression and poor physical health, all of which are frequently co-occurring among women with ACEs. METHOD/METHODS:Mediational analyses were conducted with baseline data from a sample of 290 women enrolled in a clinical trial for PTSD. Emotion regulation was assessed with the Difficulties in Emotional Regulation Scale (DERS), PTSD with the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5), depression with the Brief Symptom Inventory Depression subscale (BSI-D) and physical health with a shortened version of Medical Outcomes Study Short Form (SF-8). RESULTS:Emotion regulation significantly mediated the relationship between ACEs and all three outcomes. The estimates of the standardized indirect effects of ACEs on the health outcomes as mediated through DERS scores were as follows: PTSD β = 0.1, p < .001; depression β = 0.16, p < .001; physical health β = 0.07, p = .002. CONCLUSION/CONCLUSIONS:Interventions that focus on improving emotion regulation skills might provide an efficient "transdiagnostic" treatment strategy for both psychological and physical health problems. The study successfully tested a mediational model that identified a common pathway influencing both mental and physical health symptoms. (PsycINFO Database Record

Background: The updated 11^th edition of International Classification of Diseases (ICD-11) is expected to be released by the WHO in 2018. Disorders specifically associated with stress will be included in a separate chapter in ICD-11, and will include a revision of ICD-10 PTSD as well as a new diagnosis of complex posttraumatic stress disorder (CPTSD). The proposed symptom structures of ICD-11 PTSD and CPTSD have been validated in several studies previously, however few studies have used the International Trauma Questionnaire (ITQ), a specific measure for ICD-11 PTSD and CPTSD. Given that ICD-11 PTSD and CPTSD diagnoses are intended to be applicable across different cultures and nations, it is important that the constructs be evaluated across diverse populations and languages. Objective: Study of the psychological impact of trauma is relatively new in Lithuania, coinciding with its independence from the Soviet Union in the 1990s. Studies thus far reveal a population suffering from the effects of long-term and systematic political oppression and violence. The aim of this study was to assess the validity of the symptoms and structure of PTSD and CPTSD in a Lithuanian treatment-seeking sample as measured by the ITQ. Method: A total of 280 patients from outpatient mental health centres participated in this study. PTSD and CPTSD symptoms were measured with the ITQ. We applied confirmatory factor analysis (CFA) and latent class analysis (LCA) for analysis of data. Results and conclusions: Our study supported the ICD-11 factor structure of CPTSD, and a three-class model was supported in LCA analysis with a PTSD class, a CPTSD class, and a low symptom class. Findings support the factorial and discriminant validity of the ICD-11 proposals for PTSD and CPTSD in a unique clinical population.

BACKGROUND:Two 'sibling' disorders have been proposed for the fourthcoming 11th version of the International Classification of Diseases (ICD-11): post-traumatic stress disorder (PTSD) and complex PTSD (CPTSD). Examining psychological factors that may be associated with CPTSD, such as self-compassion, is an important first step in its treatment that can inform consideration of which problems are most salient and what interventions are most relevant. AIMS/OBJECTIVE:We set out to investigate the association between self-compassion and the two factors of CPTSD: the PTSD factor (re-experiencing, avoidance, sense of threat) and the Disturbances in Self-Organization (DSO) factor (affect dysregulation, negative self-concept and disturbances in relationships). We hypothesized that self-compassion subscales would be negatively associated with both PTSD and DSO symptom clusters. METHOD/METHODS:A predominantly female, clinical sample (n = 106) completed self-report scales to measure traumatic life events, ICD-11 CPTSD and self-compassion. RESULTS:Significant negative associations were found between the CPTSD DSO clusters of symptoms and self-compassion subscales, but not for the PTSD ones. Specifically it was also found that self-judgement and common humanity significantly predicted hypoactive affect dysregulation whereas self-judgement and isolation significantly predicted negative self-concept. CONCLUSIONS:Our results indicate that self-compassion may be a useful treatment target for ICD-11 CPTSD, particularly for symptoms of negative self-concept and affect dysregulation. Future research is required to investigate the efficacy and acceptability of interventions that have implicit foundations on compassion.

OBJECTIVE:The purpose of this study was to finalize the development of the International Trauma Questionnaire (ITQ), a self-report diagnostic measure of post-traumatic stress disorder (PTSD) and complex PTSD (CPTSD), as defined in the 11th version of the International Classification of Diseases (ICD-11). METHOD/METHODS:The optimal symptom indicators of PTSD and CPTSD were identified by applying item response theory (IRT) analysis to data from a trauma-exposed community sample (n = 1051) and a trauma-exposed clinical sample (n = 247) from the United Kingdom. The validity of the optimized 12-item ITQ was assessed with confirmatory factor analyses. Diagnostic rates were estimated and compared to previous validation studies. RESULTS:The latent structure of the 12-item, optimized ITQ was consistent with prior findings, and diagnostic rates of PTSD and CPTSD were in line with previous estimates. CONCLUSION/CONCLUSIONS:The ITQ is a brief, simply worded measure of the core features of PTSD and CPTSD. It is consistent with the organizing principles of the ICD-11 to maximize clinical utility and international applicability through a focus on a limited but central set of symptoms. The measure is freely available and can be found in the body of this paper.

This pilot study assessed the feasibility, acceptability, and initial efficacy of a skills-focused treatment delivered via video teleconferencing (VTC) to women veterans living in rural areas who had experienced military sexual trauma (MST). The Skills Training in Affective and Interpersonal Regulation (STAIR) program focuses on teaching emotion management and interpersonal skills in 8 to 10 sessions. The STAIR program may be a good fit for individuals in rural areas for whom social isolation and low social support are particularly problematic. Clinic-to-clinic VTC was used to connect a STAIR therapist with veterans for weekly individual therapy sessions. The participants (n = 10) reported high satisfaction with the intervention and would recommend the program to others. There were significant pretreatment to posttreatment improvements in social functioning, Hedge's g = 1.41, as well as in posttraumatic stress disorder symptoms, Hedge's g = 2.35; depression, Hedge's g = 1.81; and emotion regulation, Hedge's g = 2.32. This is the first report of the successful application of a skills-focused treatment via VTC for women veterans.

OBJECTIVE:We set out to investigate the association between negative trauma-related cognitions, emotional regulation strategies, and attachment style and complex post-traumatic stress disorder (CPTSD). As the evidence regarding the treatment of CPTSD is emerging, investigating psychological factors that are associated with CPTSD can inform the adaptation or the development of effective interventions for CPTSD. METHOD/METHODS:A cross-sectional design was employed. Measures of CPTSD, negative trauma-related cognitions, emotion regulation strategies, and attachment style were completed by a British clinical sample of trauma-exposed patients (N = 171). Logistic regression analysis was used to assess the predictive utility of these psychological factors on diagnosis of CPTSD as compared to PTSD. RESULTS:It was found that the most important factor in the diagnosis of CPTSD was negative trauma-related cognitions about the self, followed by attachment anxiety, and expressive suppression. CONCLUSIONS:Targeting negative thoughts and attachment representations while promoting skills acquisition in emotional regulation hold promise in the treatment of CPTSD. Further research is required on the development of appropriate models to treat CPTSD that tackle skills deficit in these areas. PRACTITIONER POINTS/UNASSIGNED:Results suggest that cognitive-behavioural interventions might be useful for the treatment of CPTSD. Targeting negative thoughts and attachment representations while promoting skills acquisition in emotional regulation hold promise in the treatment of CPTSD.

The International Classification of Diseases 11th Version (ICD-11) will include Complex Posttraumatic Stress Disorder (CPTSD) as a unique diagnostic entity comprising core PTSD and DSO (disturbances in self-organization) symptoms. The current study had three aims: (1) assessing the validity of CPTSD in a unique population of male perpetrators of intimate partner violence; (2) examining whether exposure to different types of traumatic events would be associated with the two proposed CPTSD factors, namely PTSD or DSO; and (3) assessing the differential association of various sociodemographic and symptom characteristics with each factor. Participants were 234 males drawn randomly from a sample of 2600 men receiving treatment at 66 domestic violence centers in Israel. Data were collected using the International Trauma Questionnaire (ITQ) - Hebrew version. Confirmatory factor analysis supported the factorial validity of ICD-11 CPTSD. Cumulative lifetime trauma and physical childhood neglect were associated with PTSD and DSO, while cumulative childhood violence exposure was associated only with DSO. Anxiety was associated only with DSO; depression more strongly with DSO than PTSD. Religious level contributed only to PTSD; compulsory military service only to DSO. The study supports the distinction between PTSD and DSO in the CPTSD construct and introduces the role of cultural variables.

BACKGROUND:The current study sought to advance the existing literature by providing the first assessment of the factorial and discriminant validity of the ICD-11 proposals for posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) in a nationwide level. METHODS:A nationally representative sample from Israel (n = 1,003) using a disorder-specific measure (ITQ; International Trauma Questionnaire) in order to assess PTSD and CPTSD along with the Life Events Checklist and the World Health Organization Well-Being Index. RESULTS:Estimated prevalence rates of PTSD and CPTSD were 9.0 and 2.6%, respectively. The structural analyses indicated that PTSD and disturbances in self-organization symptom clusters were multidimensional, but not necessarily hierarchical, in nature and there were distinct classes that were consistent with PTSD and CPTSD. CONCLUSIONS:These results partially support the factorial validity and strongly support the discriminant validity of the ICD-11 proposals for PTSD and CPTSD in a nationally representative sample using a disorder-specific measure; findings also supported the international applicability of these diagnoses. Further research is required to determine the prevalence rates of PTSD and CPTSD in national representative samples across different countries and explore the predictive utility of different types of traumatic life events on PTSD and CPTSD.
