According to current treatment guidelines for Complex PTSD (cPTSD), psychotherapy for adults with cPTSD should start with a “stabilization phase.” This phase, focusing on teaching self‐regulation strategies, was designed to ensure that an individual would be better able to tolerate trauma‐focused treatment. The purpose of this paper is to critically evaluate the research underlying these treatment guidelines for cPTSD, and to specifically address the question as to whether a phase‐based approach is needed. As reviewed in this paper, the research supporting the need for phase‐based treatment for individuals with cPTSD is methodologically limited. Further, there is no rigorous research to support the views that: (1) a phase‐based approach is necessary for positive treatment outcomes for adults with cPTSD, (2) front‐line trauma‐focused treatments have unacceptable risks or that adults with cPTSD do not respond to them, and (3) adults with cPTSD profit significantly more from trauma‐focused treatments when preceded by a stabilization phase. The current treatment guidelines for cPTSD may therefore be too conservative, risking that patients are denied or delayed in receiving conventional evidence‐based treatments from which they might profit.

INTRODUCTION Prior studies have addressed sexual abuse and sexual function in adult women. No studies have focused on the effect of adolescence rape on sexual functioning. AIM To investigate the effect of rape on sexual problems and on pelvic floor problems, as well as the mediating role of pelvic floor problems on sexual problems, in a homogenous group of victims of adolescence rape without a history of childhood sexual, physical, and/or emotional abuse. MAIN OUTCOME MEASURES Sexual functioning and pelvic floor functioning were assessed using self-report questionnaires. METHODS In this cross-sectional study, a group of 89 young women aged 18-25 years who were victimized by rape in adolescence was compared with a group of 114 nonvictimized controls. The rape victims were treated for posttraumatic stress disorder (PTSD) 3 years prior to participation in the study. RESULTS Three years posttreatment, rape victims were 2.4 times more likely to have a sexual dysfunction (lubrication problems and pain) and 2.7 times more likely to have pelvic floor dysfunction (symptoms of provoked vulvodynia, general stress, lower urinary tract, and irritable bowel syndrome) than nonvictimized controls. The relationship between rape and sexual problems was partially mediated by the presence of pelvic floor problems. Rape victims and controls did not differ with regard to sexual activities. CONCLUSIONS Rape victims suffer significantly more from sexual dysfunction and pelvic floor dysfunction when compared with nontraumatized controls, despite the provision of treatment for PTSD. Possibly, physical manifestations of PTSD have been left unaddressed in treatment. Future treatment protocols should consider incorporating (physical or psychological) treatment strategies for sexual dysfunction and/or pelvic floor dysfunction into trauma exposure treatments.

BACKGROUND In chronic sexual abuse victims with post traumatic stress disorder (PTSD), the hypothalamic pituitary adrenal (HPA) axis can be dysregulated. In single rape victims, PTSD symptoms are hypothesized to function as a chronic stressor leading to similar HPA-axis dysregulation. The objective of the current study was to assess HPA-axis functioning in female adolescents with rape-related PTSD, but no prior sexual trauma, in comparison to non-victimized controls. METHOD Salivary cortisol and dehydroepiandrosterone sulfate (DHEAS) were measured in 52 female adolescent rape victims with PTSD and 37 healthy adolescents at 0, 15, 30, 45 and 60 min after awakening, both under basal conditions and after 0.5 mg dexamethasone administration. RESULTS Compared to age-matched controls, adolescent rape victims with PTSD showed significantly reduced cortisol and DHEAS levels. No group differences for the effect of dexamethasone suppression were found. Both the event of rape and PTSD diagnosis, and not factors such as sleep duration, smoking, education or oral contraceptives, accounted for the neuroendocrine differences between rape victims and controls. CONCLUSIONS The results show evidence for a dysregulated HPA-axis in female adolescent victims of single sexual trauma with PTSD. The finding of hypocortisolism is consistent with endocrine dysfunctioning in chronic sexual abuse victims and may have clinical implications with regard to treatment possibilities.

Early identification of posttraumatic stress disorder (PTSD) in children is important to offer them appropriate and timely treatment. The Childrens Revised Impact of Event Scale (CRIES) is a brief self-report measure designed to screen children for PTSD. Research regarding the diagnostic validity of the CRIES is still insufficient, has been restricted to specific populations, and sample sizes have often been small. This study evaluated the reliability and validity of the 8-item (CRIES-8) and 13-item (CRIES-13) versions of the CRIES in a large clinically referred sample. The measure was completed by 395 Dutch children (7-18 years) who had experienced a wide variety of traumatic events. PTSD was assessed using the Anxiety Disorders Interview Schedule for DSM-IV: Child and Parent version. A cutoff score of 17 on the CRIES-8 and 30 on the CRIES-13 emerged as the best balance between sensitivity and specificity, and correctly classified 78%-81% of all children. The CRIES-13 outperformed the CRIES-8, in that the overall efficiency of the CRIES-13 was slightly superior (.81 and .78, respectively). The CRIES appears to be a reliable and valid measure, which gives clinicians a brief and user-friendly instrument to identify children who may have PTSD and offer them appropriate and timely treatment.

Background Prior research endorsed the establishment of sexual assault centres in the Netherlands because of the potential benefit for victims’ mental recovery. In 2012, the first Dutch sexual assault centre was founded at the University Medical Center Utrecht. The aim of the centre is to provide 24/7 coordinated and integrated services (i.e., medical, forensic, and psychological) in one location. Objective The purpose of the present study was to describe demographic, background, and assault characteristics of victims seen at the centre within one week post-assault, and their use of post-assault services in order to improve current services. Method From January 2012 to September 2013, prospective data of 108 patients were collected. To describe the population included, frequency counts and proportions were generated for categorical variables. Results The mean age was 21.3 years (SD=9.8). Most victims were female (91.7%). A large proportion of victims reported background characteristics known to increase the risk for post-traumatic stress disorder (PTSD) and revictimisation such as prior sexual abuse (32.4%), pre-existing use of mental health services (45.4%), and not living with both biological parents (61.7%). Most patients (88.9%) consulted the centre within 72 hours post-assault. The uptake of services was high: 82.4% received emergency medical care, 61.7% underwent a forensic–medical exam, 34% reported to the police, and 82.4% utilised psychological services. Conclusion To prevent revictimisation and PTSD, current psychological services could be improved with immediate trauma-focused treatments. Current forensic services may be improved with the use of standard top to toe forensic–medical examinations for both children and adults.

Background Posttraumatic stress disorder (PTSD) can be a debilitating disorder and often co-occurs with other psychiatric disorders, such as mood, behavioral, and anxiety disorders. Early identification of PTSD and psychiatric comorbidity is highly relevant in order to offer children appropriate and timely treatment. The Childrens Revised Impact of Event Scale (CRIES-13) is a reliable and valid self-report measure designed to screen children for PTSD. However, this measure is not useful as a screen for psychiatric comorbidity in children with probable PTSD. Objective This study evaluated the screening accuracy of the CRIES-Plus, that is, the CRIES-13 combined with 12 additional items to detect psychiatric comorbidity. Method The CRIES-Plus was completed by 398 Dutch children (7–18 years) exposed to various traumatic events. Psychiatric diagnoses were assessed using the Anxiety Disorders Interview Schedule for DSM-IV: Child version. Results Six additional items were significantly associated with mood disorders, three items were associated with behavioral disorders, and five items with anxiety disorders. Additional items associated with mood and anxiety disorders demonstrated good discriminatory ability, with cut-off scores of ≥14 and ≥10, respectively. Items associated with behavioral disorders had poor to fair discriminatory ability, with no clear cut-off point. Conclusions Our findings support the use of the CRIES-Plus to screen for PTSD and comorbid disorders which may help clinicians in assigning appropriate follow-up diagnostic and clinical care.

Neuroendocrine dysregulations in sexually abused children and adolescents: a systematic review

Iva A. E. Bicanic; M. Meijer; Gerben Sinnema; E.M. van de Putte; Miranda Olff

Several studies provided evidence for neuroendocrine dysregulations in adults with a history of child sexual abuse. This review focuses on neuroendocrine studies in sexually abused children and adolescents, dating from January 1, 1990 to January 1, 2007 and obtained from a systematic Medline Indexed literature search to identify endocrine correlates of child sexual abuse. Results from studies on hypothalamic-pituitary-adrenal axis (re)activity showed to be inconclusive. Studies on the sympathetic nervous system provided evidence for a higher baseline activity of this system in sexually abused children and adolescents. Factors contributing to divergent outcomes will be discussed and suggestions for future research will be presented.

The Childrens Revised Impact of Event Scale (CRIES-13) is a brief self-report measure designed to screen children for posttraumatic stress disorder (PTSD). This study investigates the psychometric properties of a Dutch version of the CRIES-13-parent version and evaluates its correlation with the child version. A sample of 59 trauma-exposed children (8 years-18 years) and their parents completed an assessment including the CRIES-13 (child/parent version) along with the Anxiety Disorders Interview Schedule for DSM-IV: Parent version. Results demonstrated good internal consistency (α = .87) with acceptable values for the 3 subscales. A strong correlation (r = .73) with another measure of PTSD and lower correlations with a behavioral measure (r = .15 to .38) were found, confirming the convergent/divergent validity. A cutoff score ≥ 31 emerged as the best balance between sensitivity and specificity, and correctly classified 83.6% of all children as having a diagnosis of PTSD. This study provides support for the reliability and validity of the CRIES-13-parent version as a screening measure for posttraumatic stress in children.

Background Efficacy studies on treatment in adolescent victims of single rape are lacking, even though sexual victimization is most likely to occur during adolescence and despite the fact that adolescents are at risk to develop subsequent posttraumatic stress disorder. Aim The aim of this prospective observational study was to evaluate the short- and long-term outcomes of a nine-session cognitive behavior group therapy (STEPS), including a parallel six-session parents’ group on rape-related symptomatology in female adolescents (13–18 years). STEPS includes psychoeducation, exposure in sensu as well as in vivo, cognitive restructuring, and relapse prevention. Methods Fifty-five female adolescents with mental health problems due to single rape, but without prior sexual trauma, received STEPS while their parents participated in a support group. Subjects were assessed on posttraumatic stress (PTS) and comorbid symptoms using self-report questionnaires prior to and directly after treatment, and at 6 and 12 months follow-up. Results Repeated measures analysis showed a significant and large decrease in symptoms of PTS, anxiety, depression, anger, dissociation, sexual concerns, and behavior problems directly after treatment, which maintained at 12 months follow-up. Time since trauma did not influence the results. Dropout during STEPS was 1.8%. Conclusions The results potentially suggest that the positive treatment outcomes at short- and long-term may be caused by STEPS. The encouraging findings need confirmation in future controlled studies on the effectiveness of STEPS because it may be possible that the treatment works especially well for more chronic symptoms, while the less chronic part of the sample showed considerable improvement on its own.

Background Delayed disclosure of rape has been associated with impaired mental health; it is, therefore, important to understand which factors are associated with disclosure latency. The purpose of this study was to compare various demographics, post-rape characteristics, and psychological functioning of early and delayed disclosers (i.e., more than 1-week post-rape) among rape victims, and to determine predictors for delayed disclosure. Methods Data were collected using a structured interview and validated questionnaires in a sample of 323 help-seeking female adolescents and young adults (12–25 years), who were victimized by rape, but had no reported prior chronic child sexual abuse. Results In 59% of the cases, disclosure occurred within 1 week. Delayed disclosers were less likely to use medical services and to report to the police than early disclosers. No significant differences were found between delayed and early disclosers in psychological functioning and time to seek professional help. The combination of age category 12–17 years [odds ratio (OR) 2.05, confidence intervals (CI) 1.13–3.73], penetration (OR 2.36, CI 1.25–4.46), and closeness to assailant (OR 2.64, CI 1.52–4.60) contributed significantly to the prediction of delayed disclosure. Conclusion The results point to the need of targeted interventions that specifically encourage rape victims to disclose early, thereby increasing options for access to health and police services.
