Impact of three variants of prolonged exposure therapy on comorbid diagnoses in patients with childhood abuse-related PTSD

ABSTRACT Recent studies indicated that Prolonged Exposure (PE) is safe and effective for posttraumatic stress disorder (PTSD). It is unclear whether PE also leads to a reduction in comorbid diagnoses. Data from a large randomized controlled trial (N = 149) on the effects of three variants of PE for PTSD were used. We examined the treatment effects on co-morbid diagnoses of depressive, anxiety, obsessive compulsive, substance abuse, psychotic, eating and personality disorders in a sample of patients with PTSD related to childhood abuse. Outcomes were assessed with clinical interviews at baseline, post-treatment and at 6- and 12-month follow-up. All variants of PE led to a decrease from baseline to post-treatment in diagnoses of depressive, anxiety, substance use and personality disorders. Improvements were sustained during follow-up. We found an additional decrease in the number of patients that fulfilled the diagnostic criteria of a depressive disorder between 6- and 12-month follow-up. No significant changes were observed for the presence of OCD, psychotic and eating disorders. Findings suggest that it is effective to treat PTSD related to childhood abuse with trauma-focused treatments since our 14-to-16 weeks PE for PTSD resulted in reductions in comorbid diagnoses of depressive, anxiety, substance use and personality disorders.

Predictors and moderators of treatment outcomes in phase-based treatment and trauma-focused treatments in patients with childhood abuse-related post-traumatic stress disorder

ABSTRACT Background: Knowledge of treatment predictors and moderators is important for improving the effectiveness of treatment for PTSD due to childhood abuse. Objective: The first aim of this study was to test the potential predictive value of variables commonly associated with PTSD resulting from a history of repeated childhood abuse, in relation to treatment outcomes. The second aim was to examine if complex PTSD symptoms act as potential moderators between treatment conditions and outcomes. Method: Data were obtained from a randomized controlled trial comparing a phase-based treatment (Skills Training in Affect and Interpersonal Regulation [STAIR] followed by Eye Movement Desensitization and Reprocessing [EMDR] therapy; n = 57) with a direct trauma-focused treatment (EMDR therapy only; n = 64) in people with PTSD due to childhood abuse. The possible predictive effects of the presence of borderline personality disorder, dissociative symptoms, and suicidal and self-injurious behaviours were examined. In addition, it was determined whether symptoms of emotion regulation difficulties, self-esteem, and interpersonal problems moderated the relation between the treatment condition and PTSD post-treatment, corrected for pre-treatment PTSD severity. Results: Pre-treatment PTSD severity proved to be a significant predictor of less profitable PTSD treatment outcomes. The same was true for the severity of dissociative symptoms, but only post-treatment, and not when corrected for false positives. Complex PTSD symptoms did not moderate the relationship between the treatment conditions and PTSD treatment outcomes. Conclusions: The current findings suggest that regardless of the common comorbid symptoms studied, immediate trauma-focused treatment is a safe and effective option for individuals with childhood-related PTSD. However, individuals experiencing severe symptoms of PTSD may benefit from additional treatment sessions or the addition of other evidence-based PTSD treatment approaches. The predictive influence of dissociative sequelae needs further research. The study design was registered in The Dutch trial register (https://www.trialregister.nl/trialreg/admin/rctview.asp?TC = 5991) NTR5991 and was approved by the medical ethics committee of Twente NL 56641.044.16 CCMO.

Changes in trauma-related cognitions predict subsequent symptom improvement during prolonged exposure in patients with childhood abuse-related PTSD

Change in negative posttraumatic cognitions is a proposed mechanism through which Prolonged Exposure (PE) leads to symptom reduction of posttraumatic stress disorder (PTSD). A strong case for posttraumatic cognitions as a change mechanism in PTSD treatment can be made by establishing temporal precedence of change in cognitions. The current study examines the temporal relationship between change in posttraumatic cognitions and PTSD symptoms during PE, using the Posttraumatic Cognitions Inventory. Patients with DSM-5 defined PTSD following childhood abuse (N = 83) received a maximum of 14–16 sessions of PE. Clinician-rated PTSD symptom severity and posttraumatic cognitions were assessed at baseline, week 4, 8, and 16 (post-treatment). Using time-lagged mixed effect regression models, we found that posttraumatic cognitions predicted subsequent PTSD symptom improvement. Notably, when using the items of an abbreviated version of the PTCI (PTCI-9), we found a mutual relationship between posttraumatic cognitions and PTSD symptom improvement. Crucially, the effect of change in cognitions on PTSD symptom change was greater than the reverse effect. The current findings corroborate change in posttraumatic cognitions as a change process during PE, but cognitions and symptoms cannot be completely separated. The PTCI-9 is a short instrument that appears suitable to track cognitive change over time.

Exposure-based treatments for childhood abuse-related post-traumatic stress disorder in adults: a health-economic evaluation

ABSTRACT Background: Prolonged exposure (PE) is an effective treatment for post-traumatic stress disorder (PTSD). Objective: This study aimed to analyse the cost-effectiveness of three exposure-based treatments in patients with childhood abuse-related PTSD. Method: A net–benefit analysis was conducted alongside a pragmatic randomized controlled trial with participants (N = 149) randomized to three conditions: PE (n = 48), intensified PE (i-PE, n = 51), and phase-based PE [Skills Training in Affective and Interpersonal Regulation (STAIR) + PE, n = 50]. Assessments took place at baseline (T0), post-treatment (T3), 6 month follow-up (T4), and 12 month follow-up (T5). Costs stemming from healthcare utilization and productivity losses were estimated using the Trimbos/iMTA questionnaire for Costs associated with Psychiatric Illness. Quality-adjusted life-years (QALYs) were based on the 5-level EuroQoL 5 Dimensions (EQ-5D-5L) using the Dutch tariff. Missing values of costs and utilities were multiply imputed. To compare i-PE to PE and STAIR + PE to PE, pair-wise unequal-variance t-tests were conducted. Net–benefit analysis was used to relate costs to QALYs and to draw acceptability curves. Results: Intervention costs did not differ across the three treatment conditions. Total medical costs, productivity losses, total societal costs, and EQ-5D-5L-based QALYs did not differ between treatment conditions either (all p > .10). At the relevant €50,000/QALY threshold, the probability of one treatment being more cost-effective than another was 32%, 28%, and 40% for PE, i-PE, and STAIR-PE, respectively. Conclusion: Three equally effective treatments were compared and no differences in cost-effectiveness between treatments were found. Therefore, we advocate the implementation and adoption of any of the treatments and endorse shared decision making.

Long term efficacy of developmentally adapted cognitive processing therapy in youth with abuse related PTSD — Follow-up of a randomized control trial

BackgroundAdolescents and young adults with abuse-related post traumatic stress disorder (PTSD) have been shown to benefit from Developmentally Adapted Cognitive Processing Therapy (D-CPT), yet long-term efficacy of D-CPT has not yet been studied. ObjectiveTo assess the long-term efficacy of D-CPT in a sample of adolescents and young adults (age 14–21 years) with childhood abuse related PTSD. Participants and settingPatients of a previously conducted multicenter randomized controlled trial which showed the efficacy of D-CPT compared to a waitlist with treatment advice (WL/TA) were invited for follow-up assessments at 6 and 12 months after the end of treatment. MethodsPrimary outcome was the PTSD symptom severity, assessed with the Clinician-administered PTSD Scale for Children and Adolescents (CAPS-CA). Secondary outcomes were self-reported PTSD severity, depression, borderline symptom severity, behavior problems, and dissociation. ResultsOf the 44 participants who received D-CPT, 28 (63 %) responded and were assessed at 6-month follow-up. At 12-month follow-up, 22 participants (50 %) responded. The majority of participants in the WL/TA group received D-CPT after the end of the trial and were hence not available for follow-up assessment. In the D-CPT group, treatment gains were maintained at 6- and 12-month follow-up in the CAPS-CA as well as in all secondary outcomes. ConclusionsThe positive effects of D-CPT were stable in adolescents and young adults with abuse-related PTSD indicating that they can benefit in the long term from a treatment with D-CPT.

Suicidal ideation, self-injury, aggressive behavior and substance use during intensive trauma-focused treatment with exposure-based components in adolescent and young adult PTSD patients

BackgroundMultiple traumata such as child sexual and/or physical abuse often result in complex psychopathologies and a range of associated dysfunctional behaviors. Although evidence-based interventions exist, some therapists are concerned that trauma-focused psychotherapy with exposure-based elements may lead to the deterioration of associated dysfunctional behaviors in adolescents and young adults. Therefore, we examined the course of suicidal ideation, self-injury, aggressive behavior and substance use in a group of abuse-related posttraumatic stress disorder (PTSD) patients during phase-based, trauma-focused PTSD treatment.MethodsDaily assessments from a randomized controlled trial (RCT) of Developmentally adapted Cognitive Processing Therapy (D-CPT) were analyzed to test for differences in the stated dysfunctional behaviors between the four treatment phases. We conducted multilevel modeling and repeated measure ANOVAs.ResultsWe did not find any significant differences between the treatment phases concerning the stated dysfunctional behaviors, either at the level of urge or at the level of actual actions. On the contrary, in some primary outcomes (self-injury, aggressive behavior), as well as secondary outcomes (distress caused by trauma, joy), we observed significant improvements.DiscussionOverall, during D-CPT, adolescents and young adults showed no deterioration in dysfunctional behaviors, while even showing improvements in some, suggesting that trauma-focused treatment preceded by skills building was not deleterious to this population. Hence, the dissemination of effective interventions such as D-CPT should be fostered, whilst the concerns of the therapists regarding exposure-based components need to be addressed during appropriate training. Nevertheless, further studies with momentary assessment, extended measurement methods, a control group and larger sample sizes are needed to confirm our preliminary findings.Trial registrationThe trial was registered at the German Clinical Trial Registry (GCTR), DRKS00004787, 18 March 2013, https://www.drks.de/DRKS00004787.

Predictors and Moderators of Treatment Outcome in Phase-Based Treatment and Trauma-Focused Treatment in Patients with Childhood Abuse-Related Post-Traumatic Stress Disorder

Predictors and Moderators of Treatment Outcome in Phase-Based Treatment and Trauma-Focused Treatment in Patients with Childhood Abuse-Related Post-Traumatic Stress Disorder

Women with abuse-related posttraumatic stress disorder sleep more fitfully but just as long as healthy controls: an actigraphic study.

Subjective reports of sleep impairments are common in individuals with posttraumatic stress disorder (PTSD), but objective assessments of sleep have yielded mixed results. We investigated sleep via actigraphy and e-diary on 6 consecutive nights in a group of 117 women with PTSD after childhood abuse (CA; PTSD group), a group of 31 mentally healthy women with a history of CA (healthy trauma controls, HTC group) and a group of 36 nontraumatized mentally healthy women (healthy controls, HC group). The PTSD group reported lower sleep quality, more nights with nightmares, and shorter sleep duration than both HTC and HC. Actigraphic measures showed more and longer sleep interruptions in the PTSD group compared to HTC and HC, but no difference in sleep duration. While the PTSD group underestimated their sleep duration, both HTC and HC overestimated their sleep duration. HTC did not differ from HC regarding sleep impairments. Sleep in women with PTSD after CA seems to be more fragmented but not shorter compared to sleep patterns of mentally healthy control subjects. The results suggest a stronger effect of PTSD psychopathology on sleep compared to the effect of trauma per se.

Does attachment predict the outcome of cognitive processing therapy for posttraumatic stress disorder in adolescent patients with interpersonal traumatization?

The attachment has emerged as a significant predictor of psychotherapy outcome. However, studies on trauma-focused treatments and adolescent samples are sparse. We analyzed the data of 43 adolescents and young adults (aged 14–21 years) with clinically relevant abuse-related posttraumatic stress disorder (PTSD) who were undergoing developmentally adapted cognitive processing therapy (D-CPT) within a multicenter, randomized clinical trial (German Clinical Trials Register; identifier: DRKS00004787). Besides clinician-rated posttraumatic stress symptoms (PTSS), attachment-related (AR) anxiety and AR avoidance were assessed using self-reports before and after treatment as well as at three-month and six-month follow-ups. Baseline attachment did not predict any changes in PTSS severity. Averaging across all assessment points, overall higher posttraumatic avoidance was associated with greater baseline AR avoidance in D-CPT. In terms of change in attachment during the trial, a greater reduction of attachment insecurities was associated with a greater reduction of PTSS severity. Results are compared with those of the control group, a wait-list condition with treatment advice (WL/TA; N = 42). AR anxiety was more often a significant variable in the models in WL/TA, whereas AR avoidance was in D-CPT. Our study does furnish initial insights into the role of attachment during trauma-focused treatment with abused adolescents and young adults.

Effects of intranasal oxytocin on threat- and reward-related functional connectivity in men and women with and without childhood abuse-related PTSD

Novel treatments that target neurobiological alterations associated with childhood trauma, particularly among those with posttraumatic stress disorder (PTSD), could mitigate negative outcomes for these at-risk individuals. PTSD is characterized by abnormalities within the brain's salience network and reward circuitry, which are modulated by intranasal oxytocin. Using a double-blind, randomized, placebo-controlled crossover design, we tested whether intranasal oxytocin (24 international units) influenced functional coupling of the amygdala with the anterior insula (AI), dorsal anterior cingulate cortex, and nucleus accumbens in response to implicitly presented fearful, angry, and happy faces among childhood trauma-exposed individuals with (n = 16, 9 women) and without PTSD (n = 18, 12 women). Psychophysiological interaction analyses revealed that oxytocin effects were limited to amygdala-AI connectivity in the fear condition, distinct for men and women, and not impacted by PTSD diagnosis. In response to fear faces, oxytocin reduced left amygdala-left AI connectivity for women but not men; reduced left amygdala-right AI connectivity among women, but increased this connectivity in men; and reduced right amygdala-right anterior insula connectivity for men, but increased it for women. Results suggest that intranasal oxytocin modulates threat salience among childhood trauma-exposed individuals and that these effects vary as a function of gender and hemisphere.

Oxytocin, PTSD, and sexual abuse are associated with attention network intrinsic functional connectivity

Childhood maltreatment is linked to Posttraumatic Stress Disorder (PTSD) in adulthood. Neural attention network function contributes to resilience against PTSD following maltreatment; oxytocin administration alters functional connectivity differentially among resilient to PTSD groups. The present study examined intrinsic connectivity between ventral and dorsal neural attention networks (VAN and DAN) to clarify the nature of dysfunction versus resilience in the context of maltreatment-related PTSD, and to explore differential dysfunction related to varied aspects of maltreatment. Oxytocin administration was examined as a factor in these relationships. Resting-state functional connectivity data were collected from 39 adults with maltreatment histories, with and without PTSD, who were randomly assigned to receive oxytocin or placebo. We found that PTSD and sexual abuse (SA) were associated with reduced VAN-DAN connectivity. There were no significant effects with regard to physical abuse. Oxytocin was associated with greater VAN-DAN connectivity strength. These preliminary findings suggest dysfunction within attentional systems in PTSD, as well as following SA. Further, oxytocin may help ameliorate attentional neurocircuitry dysfunction in individuals with PTSD and those with maltreatment histories.

Changes in Brain Volume Associated with Trauma‐Focused Cognitive Behavioral Therapy Among Youth with Posttraumatic Stress Disorder

This study investigated group differences and longitudinal changes in brain volume before and after trauma-focused cognitive behavioral therapy (TF-CBT) in 20 unmedicated youth with maltreatment-related posttraumatic stress disorder (PTSD) and 20 non-trauma-exposed healthy control (HC) participants. We collected MRI scans of brain anatomy before and after 5 months of TF-CBT or the same time interval for the HC group. FreeSurfer software was used to segment brain images into 95 cortical and subcortical volumes, which were submitted to optimal scaling regression with lasso variable selection. The resulting model of group differences at baseline included larger right medial orbital frontal and left posterior cingulate corticies and smaller right midcingulate and right precuneus corticies in the PTSD relative to the HC group, R2 = .67. The model of group differences in pre- to posttreatment change included greater longitudinal changes in right rostral middle frontal, left pars triangularis, right entorhinal, and left cuneus corticies in the PTSD relative to the HC group, R2 = .69. Within the PTSD group, pre- to posttreatment symptom improvement was modeled by longitudinal decreases in the left posterior cingulate cortex, R2 = .45, and predicted by baseline measures of a smaller right isthmus (retrosplenial) cingulate and larger left caudate, R2 = .77. In sum, treatment was associated with longitudinal changes in brain regions that support executive functioning but not those that discriminated PTSD from HC participants at baseline. Additionally, results confirm a role for the posterior/retrosplenial cingulate as a correlate of PTSD symptom improvement and predictor of treatment outcome.

Challenges in recruiting and retaining adolescents with abuse-related posttraumatic stress disorder: lessons learned from a randomized controlled trial

BackgroundResearch on effective recruitment and retention strategies for adolescents and young adults suffering from posttraumatic stress disorder is scarce. The aim of the current study was to provide data on recruitment sources, barriers, and facilitators for participation in a randomized controlled trial for young individuals with histories of sexual and/or physical abuse.MethodsStudy participants aged 14 to 21 were asked to complete a checklist on individual sources of recruitment, barriers, and facilitators for participation in the trial. Fifty-three out of the 80 study participants who were contacted completed the checklist (66.3%).ResultsMost respondents reported multiple recruitment sources, with online and media advertising search strategies indicated most frequently (45.4% of all mentions), followed by practitioner-referred sources (38.7%). Respondents’ reported barriers included additional demands of the trial (60.3%), followed by distress caused by having to talk about painful topics (15.5%). The most frequently indicated facilitators were the organizational setting (55.1%) and monetary incentives (22.2%), followed by social support (12.0%) and non-monetary incentives (10.2%). No significant differences were observed between adolescent and young adult respondents with the exception that adolescents reported significantly more frequently that they had learned about the trial from their caregiver.ConclusionsOur findings permit the formulation of recommendations for planning and conducting trials with this clientele. Future research is needed on how specific barriers can be effectively overcome.

Effect of Developmentally Adapted Cognitive Processing Therapy for Youth With Symptoms of Posttraumatic Stress Disorder After Childhood Sexual and Physical Abuse

Despite the high prevalence, evidence-based treatments for abuse-related posttraumatic stress disorder (PTSD) in adolescents have rarely been studied. To examine whether developmentally adapted cognitive processing therapy (D-CPT) is more effective than a wait-list condition with treatment advice (WL/TA) among adolescents with PTSD related to childhood abuse. This rater-blinded, multicenter, randomized clinical trial (stratified by center) enrolled treatment-seeking adolescents and young adults (aged 14-21 years) with childhood abuse-related PTSD at 3 university outpatient clinics in Germany from July 2013 to June 2015, with the last follow-up interview conducted by May 2016. Of 194 patients, 88 were eligible for randomization. Participants received D-CPT or WL/TA. Cognitive processing therapy was enhanced by a motivational and alliance-building phase, by including emotion regulation and consideration of typical developmental tasks, and by higher session frequency in the trauma-focused core CPT phase. In WL/TA, participants received treatment advice with respective recommendations of clinicians and were offered D-CPT after 7 months. All outcomes were assessed before treatment (baseline), approximately 8 weeks after the start of treatment, after the end of treatment (posttreatment), and at the 3-month follow-up. The primary outcome, PTSD symptom severity, was assessed in clinical interview (Clinician-Administered PTSD Scale for Children and Adolescents for DSM-IV [CAPS-CA]). Secondary outcomes were self-reported PTSD severity, depression, borderline symptoms, behavior problems, and dissociation. The 88 participants (75 [85%] female) had a mean age of 18.1 years (95% CI, 17.6-18.6 years). In the intention-to-treat analysis, the 44 participants receiving D-CPT (39 [89%] female) demonstrated greater improvement than the 44 WL/TA participants (36 [82%] female) in terms of PTSD severity (mean CAPS-CA scores, 24.7 [95% CI, 16.6-32.7] vs 47.5 [95% CI, 37.9-57.1]; Hedges g = 0.90). This difference was maintained through the follow-up (mean CAPS-CA scores, 25.9 [95% CI, 16.2-35.6] vs 47.3 [95% CI, 37.8-56.8]; Hedges g = 0.80). Treatment success was greatest during the trauma-focused core phase. The D-CPT participants also showed greater and stable improvement in all secondary outcomes, with between-groups effect sizes ranging from 0.65 to 1.08 at the posttreatment assessment (eg, for borderline symptoms, 14.1 [95% CI, 8.0-20.2] vs 32.0 [95% CI, 23.8-40.2]; Hedges g = 0.91). Adolescents and young adults with abuse-related PTSD benefited more from D-CPT than from WL/TA. Treatment success was stable at the follow-up and generalized to borderline symptoms and other comorbidities. German Clinical Trials Register identifier: DRKS00004787.

Using Prolonged Exposure With an Older Male U.S. Veteran With Childhood Sexual Abuse-Related PTSD

Older adults have generally not been included in randomized clinical trials of psychotherapy for posttraumatic stress disorder (PTSD). Of the case reports and treatment outcome studies that have included those aged 55 and older, most did not include men with sexual abuse-related PTSD. This case report presents the successful application of Prolonged Exposure (PE) to a 58-year-old single, Caucasian noncombat U.S. Army veteran with severe, chronic PTSD related to several sexual assaults, including childhood sexual abuse. PE is a manualized, short-term, evidence-based psychotherapy for the treatment of PTSD which involves psychoeducation, breathing retraining, in vivo exposure, and imaginal exposure. PTSD and depressive symptoms demonstrated clinically meaningful improvement during the course of treatment. In addition, he experienced significant improvement in quality of life as well as meaning and purpose from baseline to posttreatment. Implications for clinically working with older men with untreated childhood sexual abuse-related PTSD later in life are presented. Future research directions are discussed.

General psychopathology factor and unresolved-disorganized attachment uniquely correlated to white matter integrity using diffusion tensor imaging

BackgroundA dimensional approach of psychopathology focuses on features and risk factors that are shared across diagnoses. In support for this dimensional approach, studies point to a general psychopathology factor (GPF) associated with risk for multiple psychiatric disorders. It is, however, unknown how GPF relates to white matter integrity (WMI). In the current diffusion tensor imaging (DTI) study, we examined how GPF relates to abnormalities in a skeleton representation of white matter tracts, taking into account a trans-diagnostic risk factor: unresolved-disorganized attachment (Ud) resulting from loss or trauma. MethodsUnique associations between GPF, Ud, and WMI were examined in a combined sample of adolescents (N = 63) with childhood sexual abuse-related posttraumatic stress disorder (N = 18), anxiety and depressive disorders (N = 26) and without psychiatric disorder (N = 19). WMI was measured using DTI. Ud was measured using the Adult Attachment Interview. We controlled for puberty stage, gender, age, and IQ. ResultsControlling for GPF, Ud was associated with reduced fractional anisotropy (FA) in the splenium and inferior fronto-occipital fasciculus (IFOF). Controlling for Ud, GPF was associated with reduced FA in the genu and body of the corpus callosum. ConclusionsDecreasing WMI in the genu and body with increasing psychopathology across diagnoses suggests demyelinization in these areas and may underlie comorbidity and presence of symptoms that transcend psychopathological diagnoses. In contrast, trauma-related WMI reductions in the splenium and IFOF may account for heterogeneity within diagnostic categories as a function of childhood trauma. These findings support the importance of a dimensional approach in addition to traditional diagnostic classifications in clinical research and practice.

Emotion regulation is associated with PTSD and depression among female adolescent survivors of childhood sexual abuse.

Sexual abuse experienced in childhood and adolescence is associated with severity of posttraumatic stress disorder (PTSD), depressive symptoms, and emotion regulation difficulties. The current study examined the relationships among these factors in a sample of adolescents with sexual abuse-related PTSD. It was hypothesized that (a) self-perceived emotion regulation difficulties would predict severity of PTSD and depressive symptoms, and that (b) depressive symptoms would mediate the relationship between emotion regulation difficulties and PTSD. Ninety treatment-seeking female adolescents with a history of sexual abuse were evaluated using the Child PTSD Symptom Scale-Interview and completed the Negative Mood Regulation Questionnaire and the Beck Depression Inventory as part of a baseline evaluation. Greater emotion regulation difficulties were associated with greater severity of PTSD and depressive symptoms. In addition, the relationship between emotion regulation difficulties and PTSD severity was mediated by depressive symptoms. However, the reverse was also true: the relationship between emotion regulation difficulties and depressive symptoms was mediated by PTSD symptoms. Mediation analyses showed that emotion regulation difficulties were associated with both PTSD and depressive symptoms rather than fitting a unidirectional model. These findings are consistent with and extend previous research and highlight the importance of emotion regulation in adolescent survivors of sexual abuse. (PsycINFO Database Record

Emotional face processing in adolescents with childhood sexual abuse-related posttraumatic stress disorder, internalizing disorders and healthy controls

Childhood Sexual Abuse related posttraumatic stress disorder (CSA-related PTSD), and anxiety and depressive disorders (clinical depression) have profound though differential impact on adolescent emotion regulation, attention bias and emotional face processing. We hypothesized increased negative attention bias for emotional faces and altered brain functioning in CSA-related PTSD compared to internalizing disorders and healthy controls in a cross-sectional fMRI study using an emotional face processing task in 19 12-20-year-old adolescents with CSA-related PTSD, 26 with internalizing disorders and 26 healthy controls.Outcome measures were reaction times, subjective ratings of emotional faces, and brain activation patterns for whole brain and for regions of interest. Compared to both other groups adolescents with CSA-related PTSD showed significantly slower reaction times and the highest subjective rating of emotional faces. On whole brain and ROI level, no significant group differences were found. Self-reported depressive, posttraumatic or dissociative symptoms were not associated with differences in task-related brain activity. Results support the hypothesis of increased negative attention bias for fearful and neutral faces in CSA-related PTSD versus both other groups. The absence of neural differences might indicate a brain-behavior neuro-imaging gap to be closed by larger and IQ matched samples or more sensitive paradigms to elicit emotion processing.

Functional brain alterations during self-reference processing in adolescents with sexual abuse-related post-traumatic stress disorder: A preliminary report

ABSTRACTWe proposed to explore the functional brain changes during a self-reference processing (SRP) task in adolescents with sexual abuse-related post-traumatic stress disorder (N = 10), compared with healthy adolescents (N = 10). While patients showed no behavioral disturbances in (SRP), they exhibited changes in activity and connectivity in regions involved in emotional regulation (amygdala and dorsal prefrontal cortex) and semantic memory (temporal and ventrolateral prefrontal regions). These preliminary results suggest that these alterations may have an effect on self-esteem which may contribute to a possible retention and impairment of symptoms in adulthood.

Rethinking traditional behaviour management to better support complex trauma-surviving students

Children and adolescents who have survived complex trauma have suffered the type of ongoing and repeated traumatic experience that includes factors such as physical, sexual, and/or emotional abuse, significant neglect, and/or family violence. Complex childhood trauma (sometimes referred to as paediatric or child maltreatment-related post traumatic stress disorder (De Bellis and Kuchibhatla, 2006) can have a significant impact on the developing nervous system which can lead to impairment in the capacity to relate and to emotionally self-regulate. During the schooling years, this can lead to the presentation of concerning school behaviours that schools tend to respond to with equally as concerning punitive consequences, often involving practices of exclusion. This article will emphasize the importance of schools accessing and then encompassing learnings from neuroscience into their behaviour management policies and practices. Neuroscience has provided an extra explanatory framework to complement understandings of student behaviour drawn from the clinical sciences. It is not only explaining why and how some of these student behaviours occur, but is also providing a different template of possibility for enhancing the educational and life outcomes for this vulnerable group of young people through more effective and more inclusive school practices.
