Prevalence and predictive value of ICD-11 post-traumatic stress disorder and Complex PTSD diagnoses in children and adolescents exposed to a single-event trauma

Intergenerational mental health effects of traumatic victimization in Nepal: A 3-D theory study

BACKGROUND

Intergenerational transmission of trauma is a major focus of international research. Epigenetic, complex-trauma, and intergenerational abuse pattern transmission theoretical explanations all have existing empirical support. Three-D theory argues that in addition to trauma victimization severity, victimization invasiveness and exploitativeness have important independent effects. Moreover, 3-D theory claims that a positive 3-way interaction occurs between trauma victimization invasiveness, exploitativeness, and severity. This study examines the 3-D hypotheses in the context of intergenerational trauma effects on adolescent depression symptoms and suicidal ideation in generation two. Three-D theory may play a particularly important role in intergenerational trauma effects for female victims in the context of conservative South Asian sex role norms.

OBJECTIVE

Test for main effects, two-way, and three-way interaction effects of invasiveness, exploitativeness, and severity of traumatic victimization on intergenerational transmission to adolescent depression and suicidal ideation in generation two. Pathways from maternal depression and borderline personality symptoms as well as physical and sexual abuse and neglect of the adolescent child were also tested.

PARTICIPANTS

and setting. Participants were a nationally representative, random, multi-stage cluster sample of 1089 Nepali mothers and their 15-17 year old adolescent children.

METHODS

Regression models with adjustments for clustering within municipality were used to test the hypotheses.

RESULTS

One in four Nepali adolescents had considered suicide; more than half had high depression scores. A three-way interaction effect between maternal trauma invasiveness, exploitativeness, and severity was positively associated with adolescent depression symptoms. A two-way interaction effect between exploitativeness and severity of maternal trauma was positively associated with adolescent suicidal ideation. Maternal depression, BPD symptoms, and very severe physical abuse of the adolescent were also associated with adolescent depression symptoms.

CONCLUSION

Further research is needed to measure and investigate invasiveness, exploitativeness, and severity of traumatic victimization as they bear on intergenerational transmission of trauma. Examination of intergenerational transmission of self-concept as a potential vector is recommended.

Characteristics of complex posttraumatic stress disorder (PTSD) in young people with PTSD following multiple trauma exposure

BACKGROUND

Complex PTSD (CPTSD) is a relatively new diagnosis. The objective of the present study was to investigate how trauma characteristics, comorbid psychopathology and cognitive and social factors experienced by children and adolescents with a posttraumatic stress disorder (PTSD) diagnosis following exposure to multiple traumatic events differs between those who meet the criteria for CPTSD and those who do not.

METHOD

The present research used baseline data from the DECRYPT trial (BMJ Open, 2021, 11, e047600). Participants (n = 120) were aged 8-17 years and had exposure to multiple traumas and a PTSD diagnosis. The data collected comprised self-report and parent/caregiver-report questionnaires and interviews. Three primary analyses were conducted, comparing number of trauma types, prevalence of sexual trauma and prevalence of intrafamilial abuse between the CPTSD and PTSD-only groups. A range of comorbid psychopathology and cognitive and social factors were compared between the groups in an exploratory secondary analysis. All analyses were preregistered.

RESULTS

The CPTSD group (n = 72, 60%) had a significantly higher frequency of sexual trauma than the PTSD-only group (n = 48, 40%). The groups did not significantly differ on number of trauma types or prevalence of intrafamilial abuse. From the secondary analysis, the CPTSD group were found to have significantly higher scores on measures of negative post-traumatic cognitions, depression and panic. These results were replicated in correlation analyses using a continuous measure of CPTSD symptoms.

CONCLUSIONS

A large proportion of youth exposed to multiple traumatic events met criteria for CPTSD. Sexual trauma appears to be related to CPTSD symptoms. Youth with CPTSD appear to have greater severity of comorbid depression and panic symptoms, as well as more negative post-traumatic cognitions. Further investigation could focus on the directionality and mechanisms for these associations.

A Systematic Review of the Assessment of ICD-11 Complex Post-Traumatic Stress Disorder (CPTSD) in Young People and Adults

Complex post-traumatic stress disorder (CPTSD) was introduced in the International Classification of Diseases (ICD) 11 in 2013 to simplify diagnosis and increase clinical utility. Given the recent ICD-11 conceptualisation, there is no standard approach for its assessment, and a review of research is necessary. This systematic review focuses on ICD-11 CPTSD assessment in young people aged 7 to 17 and adults aged 18 and above, examining measures, differentiating features and clinical considerations. Data from five databases are reviewed using a narrative synthesis approach and the quality of evidence is assessed and discussed. A total of 36 studies involving 5901 participants recruited from clinical settings and 1458 professionals with CPTSD assessment experience were included. Studies predominantly focused on adults, and the most used measure for assessment was the International Trauma Questionnaire. Papers focusing on differentiating features highlighted increased symptom severity, impairment and difficulties in individuals with CPTSD, compared to those with PTSD across various characteristics in both young people and adults. This review also identified the importance of a sensitive clinical approach with adaptations based on culture and age. Although gold-standard recommendations cannot be made, this paper offers tentative clinical practice recommendations and considerations regarding ICD-11 CPTSD assessment.

Complex posttraumatic stress disorder in adolescence: A two-year follow-up study

BACKGROUND

Complex posttraumatic stress disorder is a new diagnosis in the 11th edition of the International Classification of Diseases (ICD-11). There is a need for a better understanding of complex PTSD in children and adolescents.

OBJECTIVE

The study aimed to estimate the factors associated with chronic complex PTSD versus recovery of complex PTSD in adolescents in a 2-year follow-up study.

METHOD

In total, 66 adolescents, mean age 14.5, 73% female, identified as having complex PTSD using self-report at baseline recruited from a general population sample, were included in the study. The International Trauma Questionnaire - Child and Adolescent Version (ITQ-CA) was used for the assessment of complex PTSD.

RESULTS

Overall, 36% of the study sample has been identified as having chronic complex PTSD over 2 years, 10% met the criteria for PTSD at a 2-year follow-up, and 54% recovered. A higher risk for chronic complex PTSD was associated with exposure to more traumatic events and more life-stressors over the 2 years, low social network, low positive social support, bullying at school, and loneliness.

CONCLUSION

The study found that around one-third of the traumatized youth had a prolonged trajectory of complex PTSD symptoms, which were associated with negative life experiences and social difficulties.

[Posttraumatic stress disorder in children and adolescents: results of a cross-sectional study on the effects of the newly formulated PTSD and CPTSD diagnoses in the ICD-11]

BACKGROUND

ICD-11 presents narrowed criteria for posttraumatic stress disorder (PTSD) and introduces complex PTSD (CPTSD) with additional difficulties in self-organization (DSO). These changes can have significant effects on the frequency of the diagnosis. The aim of this study was to investigate which ICD-11 symptom clusters cause children and adolescents to miss the diagnosis and whether caregivers are more likely to attribute changes in DSO to developmental level or to the traumatic event, and how these attributions are in turn related to symptom severity.

METHODS

N = 88 German-speaking children and adolescents (age: 7-17 years) after traumatic events and N = 79 caregivers participated between September 2019 and November 2020 in a survey on PTSD symptom severity (CATS-2) and attribution of DSO symptoms (caregiver questionnaire).

RESULTS

The ICD-11 criteria (CATS‑2 and a developmentally adapted version) showed lower frequency rates for PTSD as compared to DSM‑5 and ICD-10. The ICD-11 clusters re-experiencing and hyperarousal were met the least often. Changes in DSO symptoms were predominantly rated as event-related. This attribution was associated with higher PTSD and DSO symptom severity in caregiver reports. The age-related attribution was associated with higher DSO-symptom severity, but not PTSD symptom severity in caregiver reports.

DISCUSSION

In the context of the diagnostic process and the revision of diagnostic instruments for ICD-11 (C)PTSD, development-specific symptoms should be taken into account. The trauma-related differentiation of DSO symptom changes as compared to development-related fluctuations is challenging and therefore requires several sources of information.

Trauma and mental disorder: multi-perspective depictions in Top Boy

Psychiatry has often had an uneasy relationship with popular culture as depictions of mental health may be stigmatising and inaccurate. A recent critically acclaimed series, Top Boy, set in a crime-filled fictional housing estate in the London Borough of Hackney offers an informed and fairly balanced insight into broad mental health-related themes including racial trauma embodied in social inequities, the syndemic of mental disorder, substance misuse and gang-based crime as well as the psychosocial ramifications of illustrated mental health conditions. From both idiographic and nomothetic perspectives, Top Boy touches on a rich variety of structural determinants of mental health, as well as individual and environmental predisposition to mental disorder and substance misuse. The show offers an opportunity for education for both the broader society and the groups which suffer these syndemics. An understanding of how structural factors epidemiologically affect what psychiatric conditions individuals are likely to suffer, how they can be better reached by psychiatric services, and what interventions can help improve the socioeconomic factors that lead to the behaviours/paths that individuals end up is vital for public mental health policy.

Mobile and Web-Based Partnered Intervention to Improve Remote Access to Pain and Posttraumatic Stress Disorder Symptom Management: Recruitment and Attrition in a Randomized Controlled Trial

BACKGROUND

Increasing access to nonpharmacological interventions to manage pain and posttraumatic stress disorder (PTSD) is essential for veterans. Complementary and integrative health (CIH) interventions can help individuals manage symptom burden with enhanced accessibility via remotely delivered health care. Mission Reconnect (MR) is a partnered, self-directed intervention that remotely teaches CIH skills.

OBJECTIVE

The purpose of this paper is to describe the recruitment, onboarding phase, and attrition of a fully remote randomized controlled trial (RCT) assessing the efficacy of a self-directed mobile and web-based intervention for veterans with comorbid chronic pain and PTSD and their partners.

METHODS

A total of 364 veteran-partner dyads were recruited to participate in a mixed methods multisite waitlist control RCT. Qualitative attrition interviews were conducted with 10 veterans with chronic pain and PTSD, and their self-elected partners (eg, spouse) who consented but did not begin the program.

RESULTS

At the point of completing onboarding and being randomized to the 2 treatment arms, of the 364 recruited dyads, 97 (26.6%) failed to complete onboarding activities. Reported reasons for failure to complete onboarding include loss of self-elected partner buy-in (n=8, 8%), difficulties with using remote data collection methods and interventions (n=30, 31%), and adverse health experiences unrelated to study activities (n=23, 24%). Enrolled veterans presented at baseline with significant PTSD symptom burden and moderate-to-severe pain severity, and represented a geographically and demographically diverse population. Attrition interviews (n=10) indicated that misunderstanding MR including the intent of the intervention or mistaking the surveys as the actual intervention was a reason for not completing the MR registration process. Another barrier to MR registration was that interviewees described the mailed study information and registration packets as too confusing and excessive. Competing personal circumstances including health concerns that required attention interfered with MR registration. Common reasons for attrition following successful MR registration included partner withdrawal, adverse health issues, and technological challenges relating to the MR and electronic data collection platform (Qualtrics). Participant recommendations for reducing attrition included switching to digital forms to reduce participant burden and increasing human interaction throughout the registration and baseline data collection processes.

CONCLUSIONS

Challenges, solutions, and lessons learned for study recruitment and intervention delivery inform best practices of delivering remote self-directed CIH interventions when addressing the unique needs of this medically complex population. Successful recruitment and enrollment of veterans with chronic pain and PTSD, and their partners, to remote CIH programs and research studies requires future examination of demographic and symptom-associated access barriers. Accommodating the unique needs of this medically complex population is essential for improving the effectiveness of CIH programs. Disseminating lessons learned and improving access to remotely delivered research studies and CIH programs is paramount in the post-COVID-19 climate.

Complex post-traumatic stress disorder (CPTSD) of ICD-11 in youths with childhood maltreatment: Associations with age of exposure and clinical outcomes

BACKGROUND

Exposure to childhood maltreatment (CM) increases the risk of psychiatric morbidity in youths. The new Complex Post-Traumatic Stress Disorder (CPTSD) diagnosis captures the heterogeneity and complexity of clinical outcomes observed in youths exposed to CM. This study explores CPTSD symptomatology and its association with clinical outcomes, considering the impact of CM subtypes and age of exposure.

METHODS

Exposure to CM and clinical outcomes were evaluated in 187 youths aged 7-17 (116 with psychiatric disorder; 71 healthy controls) following the Tools for Assessing the Severity of Situations in which Children are Vulnerable (TASSCV) structured interview criteria. CPTSD symptomatology was explored by confirmatory factor analysis, considering four subdomains: post-traumatic stress symptoms, emotion dysregulation, negative self-concept and interpersonal problems.

RESULTS

Youths exposed to CM (with or without psychiatric disorders) showed greater internalizing, externalizing and other symptomatology, worse premorbid adjustment and poorer overall functioning. Youth with psychiatric disorder and exposed to CM reported more CPTSD symptomatology, psychiatric comorbidity and polypharmacy and earlier onset of cannabis use. Different subtypes of CM and the developmental stage of exposure differentially impact CPTSD subdomains.

LIMITATIONS

Small percentage of resilient youths was studied. It was not possible to explore specific interactions between diagnostic categories and CM. Direct inference cannot be assumed.

CONCLUSIONS

Gathering information on type and age of exposure to CM is clinically useful to understand the complexity of psychiatric symptoms observed in youths. Inclusion of the CPTSD diagnosis should increase the implementation of early specific interventions, improving youths' functioning and reducing the severity of clinical outcomes.

Understanding the relationships between trauma type and individual posttraumatic stress symptoms: a cross-sectional study of a clinical sample of children and adolescents

BACKGROUND

Characteristics of traumatic events may be associated with the level and specific manifestation of posttraumatic stress symptoms (PTSS). This study examined the differences and similarities between overall levels, profiles and networks of PTSS after sexual trauma, domestic violence, community violence, non-interpersonal trauma, sudden loss or serious illness of a loved one, and severe bullying or threats.

METHODS

PTSS were measured in a clinical sample of 4,921 children and adolescents (6-18 years old, M = 14.0, SD = 2.7, 63.7% female) referred to Child and Adolescent Mental Health Services. We compared 95% confidence intervals (CI) for each symptom with 95% CI for overall PTSS within each trauma type (self-reported worst trauma). We also computed cross-sectional networks and searched for differences in networks according to trauma type and overall symptom level.

RESULTS

The overall frequencies of PTSS were highest following sexual trauma; somewhat lower for domestic violence and severe bullying or threats and lowest after community violence, non-interpersonal trauma and sudden loss or serious illness. Psychological cue reactivity, avoidance and difficulties with sleeping and concentrating were generally among the most frequent symptoms. Sexual trauma, domestic violence and severe bullying or threats were associated with higher frequencies of negative beliefs and persistent negative emotional states. Few differences in symptom networks across trauma type emerged.

CONCLUSION

Different types of trauma exposure may be associated with different profiles of symptom frequencies. Knowledge about this may be useful for clinicians and for the movement towards evidence-based personalized psychological treatment.

Developmental trauma: Conceptual framework, associated risks and comorbidities, and evaluation and treatment

Children exposed to adverse childhood experiences (ACEs) and pervasive interpersonal traumas may go on to develop PTSD and, in most cases, will further undergo a significant shift in their developmental trajectory. This paper examines contemporary research on Developmental Trauma (DT), which is inextricably linked to disruptions in social cognition, physiological and behavioral regulation, and parent-child attachments. Developmental trauma associated with early experiences of abuse or neglect leads to multi-faceted and longstanding consequences and underscores critical periods of development, complex stress-mediated adaptations, and multilevel, trans-theoretical influences in the diagnostic formulation and treatment of traumatized children, adolescents, and adults. Psychological and medical correlates of Developmental Trauma Disorder are considered, and directions for future research are discussed.

Complex post-traumatic stress disorder

Complex post-traumatic stress disorder (complex PTSD) is a severe mental disorder that emerges in response to traumatic life events. Complex PTSD is characterised by three core post-traumatic symptom clusters, along with chronic and pervasive disturbances in emotion regulation, identity, and relationships. Complex PTSD has been adopted as a new diagnosis in the ICD-11. Individuals with complex PTSD typically have sustained or multiple exposures to trauma, such as childhood abuse and domestic or community violence. The disorder has a 1-8% population prevalence and up to 50% prevalence in mental health facilities. Progress in diagnostics, assessment, and differentiation from post-traumatic stress disorder and borderline personality disorder is reported, along with assessment and treatment of children and adolescents. Studies recommend multicomponent therapies starting with a focus on safety, psychoeducation, and patient-provider collaboration, and treatment components that include self-regulatory strategies and trauma-focused interventions.

Exploring the Effect of a Nature-based Virtual Reality Environment on Stress in Adolescents

Adolescent mental health is a growing public health issue, with 30% of teens reporting increased stress and 20% of adolescents suffering from depression. Given the scarcity and lack of scalability of mental health services available, the use of self-administered, evidence-based technologies to support adolescent mental health is both timely and imperative. We conducted a mixed-methods pilot study with 31 adolescents ages 14-19 (m = 17.97) to explore the self-administration of a nature-based virtual reality tool. Participant use of the VR environment ranged from 1 to 10 sessions (m = 6.6) at home over a 2-week period while reporting their daily stress and mood levels. All participants completed all of the study protocols, indicating our protocol was feasible and the VR environment engaging. Post-study interviews indicated that most participants found the VR tool to be relaxing and helpful with stress. The themes of Calm Down, Relaxation, and Escape emerged to articulate the participants' experiences using the VR environment. Additionally, participants provided rich data regarding their preferences and activity in the VR environment as well as its effect on their emotional states. Although the sample size was insufficient to determine the impact on depression, we found a significant reduction in momentary stress as a result of using the VR tool. These preliminary data inform our own virtual reality environment design, but also provide evidence of the potential for self-administered virtual reality as a promising tool to support adolescent mental health.

Trauma exposure and factors associated with ICD-11 PTSD and complex PTSD in adolescence: a cross-cultural study in Japan and Lithuania

Aims

Cross-cultural studies of posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) based on ICD-11 diagnostic criteria are scarce, especially in adolescence. The study aimed to evaluate the trauma exposure, prevalence and factors associated with PTSD and CPTSD in general populations of adolescents in Lithuania and Japan.

Methods

The study sample comprised 1746 adolescents from Lithuania (n = 832) and Japan (n = 914), 49.8% female. The mean age of study participants was 15.52 (s.d. = 1.64), ranging from 12 to 18 years. ICD-11 posttraumatic disorders were assessed using the International Trauma Questionnaire – Child and Adolescent version (ITQ-CA).

Results

More than half of the adolescents in a total sample (61.5%) reported exposure to at least one traumatic event in their lifetime, 80.0% in Lithuania and 44.6% in Japan, with a higher prevalence of interpersonal trauma in Lithuania and more natural disaster exposure in Japan. The prevalence of PTSD was 5.2% (95% CI 3.8–6.9%) and 2.3% (95% CI 1.4–3.5%), CPTSD 12.3% (95% CI 10.1–14.7%) and 4.1% (95% CI 2.9–5.5%) in Lithuanian and Japanese samples, respectively. Cumulative trauma exposure, female gender, loneliness and financial difficulties in family predicted both PTSD and CPTSD in the total sample. Loneliness discriminated CPTSD v. PTSD in both Lithuanian and Japanese samples.

Conclusions

This cross-cultural study is among the first which reported different patterns of trauma exposure in Asian Japanese and Lithuanian adolescents in Europe. Despite differences in trauma exposure and PTSD/CPTSD prevalence, we found similar predictors in both studies, particularly the importance of cumulative trauma exposure for PTSD/CPTSD, and social interpersonal factors for the risk of CPTSD. The study supports the universality of traumatic stress reactions to adverse life experiences in adolescence across cultures and regions and highlights different levels of traumatisation of adolescents in various countries.

Valeriana jatamansi Jones ex Roxb. Against Post-Traumatic Stress Disorder, Network Pharmacological Analysis, and In Vivo Evaluation

Zhi zhu xiang (ZZX) is the root and rhizome of Valeriana jatamansi Jones ex Roxb. Recent studies have shown that ZZX can exert antianxiety, antidepressant, and sedative effects. Because post-traumatic stress disorder (PTSD) is similar to depression and anxiety in terms of its etiology, pathogenesis, and clinical manifestations, it is possible that ZZX may also be useful for the prevention and treatment of PTSD. In this study, a mouse model of PTSD was established and used to study the pharmacological action of a 95% ethanol extract of ZZX on PTSD via a series of classic behavioral tests. We found that a 95% ethanol extract of ZZX was indeed effective for relieving the symptoms of PTSD in mice. Moreover, network pharmacology analysis was used to predict the potential active ingredients, targets, and possible pathways of ZZX in the treatment of PTSD. The neurotransmitter system, the hypothalamic-pituitary-adrenal (HPA) axis, and the endocannabinoid (eCB) system were identified to be the most likely pathways for anti-PTSD action in ZZX. Due to the lack of a falsification mechanism in network pharmacology, in vivo tests were carried out in mice, and the expression levels of neurotransmitters, hormones, and genes of key targets were detected by enzyme-linked immunosorbent assay and real-time PCR to further verify this inference. Analysis showed that the levels of norepinephrine, 5-hydroxytryptamine, and glutamic acid were increased in the hippocampus, prefrontal cortex, and amygdala of PTSD mice, while the levels of dopamine and γ-aminobutyric acid were decreased in these brain regions; furthermore, ZZX could restore the expression of these factors, at least to a certain extent. The levels of adrenocorticotropic hormone, corticosterone, and corticotropin-releasing hormone were increased in these different brain regions and the serum of PTSD mice; these effects could be reversed by ZZX to a certain extent. The expression levels of cannabinoid receptor 1 and diacylglycerol lipase α mRNA were decreased in PTSD mice, while the levels of fatty acid amide hydrolase and monoacylglycerol lipase mRNA were increased; these effects were restored by ZZX to a certain extent. In conclusion, our findings suggest that ZZX may provide new therapeutic pathways for treating PTSD by the regulation of neurotransmitters, the HPA, and expression levels of eCB-related genes in the brain.

Interpersonal Trauma Exposure and Interpersonal Problems in Adolescent Posttraumatic Stress Disorder

Traumatic experiences have been differentiated as interpersonal (i.e., the direct result of actions by other people) or noninterpersonal (i.e., other life-threatening events, such as severe accidents). Interpersonal trauma exposure generally has been shown to be associated with more severe posttraumatic stress disorder (PTSD) symptoms than noninterpersonal trauma exposure. Interpersonal problems also tend to be associated with trauma exposure and PTSD symptoms, but it is unclear whether a mediating association exists between trauma type, interpersonal problems, and PTSD symptoms. A clinical sample of 4,275 adolescents (age range: 12-18 years) from the National Child Traumatic Stress Network Core Data Set were classified as having experienced interpersonal trauma, noninterpersonal trauma, or both. Interpersonal problems were operationalized by social problem behaviors (e.g., immature and dependent behaviors) and aggressive behaviors on the Child Behavior Checklist. The results of path analyses showed that cumulative interpersonal trauma exposure was both directly and indirectly associated with PTSD symptoms via social problem behaviors but not aggressive behaviors, total effect β = .20, 95% CI [.17, .23]. In a second model, path analyses showed that cumulative interpersonal trauma exposure was associated directly and indirectly via PTSD symptoms with social problem behaviors, total effect β = .15, 95% CI [.11, .18], and aggressive behaviors, total effect β = .13, 95% CI [.09, .17]. These findings suggest that during adolescence, interpersonal problems play an important role in the association between interpersonal trauma exposure and PTSD symptoms.

PTSD and complex PTSD in adolescence: discriminating factors in a population-based cross-sectional study

Background: Chronic and repeated trauma are well-established risk factors for complex posttraumatic stress disorder (CPTSD) in adult samples. Less is known about how trauma history and other factors contribute to the development of CPTSD in adolescence. Objective: The aim of this study was to assess the potential contribution of trauma history and social factors to CPTSD in adolescents. Method: In a cross-sectional community study of 1299 adolescents aged 12-16 years, PTSD (n = 97) and CPTSD (n = 108) was assessed with the Child and Adolescent version of the International Trauma Questionnaire (ITQ-CA). Trauma exposure, family functioning, school problems, and social support as potential discriminating factors between the PTSD and CPTSD groups were investigated. Results: Cumulative trauma exposure did not discriminate between PTSD and CPTSD in this sample. CPTSD was associated with family problems (such as financial difficulties and conflicts in the home), school problems (bullying and learning difficulties), and lack of social support. Conclusions: Our study indicates that factors other than cumulative trauma are important for the development of CPTSD in adolescence. Interventions targeting adolescent's social environment both at home and at school may be beneficial.

Commentary: The need for research on PTSD in Children and adolescents - a commentary on Elliot et al. (2020)

The recent release of the 11th version of The International Classification of Diseases (ICD-11: WHO, 2018) marked a significant departure from the previous similarities between it and the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; APA, 2013) in terms of their conceptualization of posttraumatic stress disorder (PTSD). The ICD-11 proposed a reduced symptom set for PTSD and a sibling disorder called Complex PTSD. There have been numerous studies that have provided support for the integrity of, and distinction between, PTSD and CPTSD diagnoses in adult samples. Elliot and colleagues (2020) have added to the research literature by providing a valuable examination of the differences between ICD and DSM PTSD/CPTSD in a sample of youth aged 8 to 17 years. This commentary reviews this study and reflects on the need for greater understanding of developmental changes in the presentation of PTSD and Complex PTSD.

Response of young patients with probable ICD-11 complex PTSD to treatment with developmentally adapted cognitive processing therapy

Background: ICD-11 features Complex Posttraumatic Stress Disorder (CPTSD) as a new diagnosis. To date, very few studies have investigated CPTSD in young patients, and there is a need for evidence on effective treatment. Objective: The present study evaluates the applicability of developmentally adapted cognitive processing therapy (D-CPT) for CPTSD in young patients in a secondary analysis of the treatment condition of a randomized controlled trial (RCT) investigating the efficacy of D-CPT. Methods: The D-CPT treatment group in the original study included 44 patients (14-21 years) with DSM-IV PTSD after childhood abuse. We used the ICD-11 algorithm to divide the sample into a probable CPTSD and a non-CPTSD group. We performed multilevel models for interviewer-rated and self-rated PTSD symptoms with fixed effects of group (CPTSD, non-CPTSD) and time (up to 12 months follow-up) and their interaction. Treatment response rates for both groups were calculated. Results: Nineteen (43.2%) patients fulfilled criteria for probable ICD-11 CPTSD while 25 (56.8%) did not. Both CPTSD and non-CPTSD groups showed symptom reduction over time. The CPTSD group reported higher symptom severity before and after treatment. Linear improvement and treatment response rates were similar for both groups. D-CPT reduced symptoms of disturbances in self-regulation in both groups. Discussion: Both, patients with and without probable ICD-11 CPTSD seemed to benefit from D-CPT and the treatment also reduced disturbances in self-regulation. Conclusion: This study presents initial evidence of the applicability of D-CPT in clinical practice for young patients with CPTSD. It remains debatable whether CPTSD implies different treatment needs as opposed to PTSD.
