Rape-related symptoms in adolescents: short- and long-term outcome after cognitive behavior group therapy

A Systematic Review of Evidence-Based Treatments for Adolescent and Adult Sexual Assault Victims

BACKGROUND

Sexual assault (SA) is a serious crime that is a prevalent mental and public health problem.

AIMS

Addressing the needs of SA victims and providing appropriate treatment are essential to reduce potential adverse short- and long-term outcomes.

METHODS

Our team undertook an extensive systematic literature review (published between January 2006 and July 2021) to provide evidence-based mental health intervention recommendations for adolescent and adult victims of SA. Where SA-specific research was limited, the literature and clinical practice guidelines on treatments for trauma-induced post-traumatic stress disorder (PTSD) were reviewed to provide additional information to formulate recommendations.

RESULTS

Findings strongly support several primary psychotherapy treatments: cognitive behavioral therapy, cognitive processing therapy, eye movement desensitization and reprocessing, narrative exposure therapy, and prolonged exposure therapy. Complementary (aerobic exercise, art, drama, and music therapy) and pharmacological treatments were explored.

CONCLUSIONS

Mental health nurses who provide services for victims of SA can utilize this overview to guide recommendations for treatment of SA trauma and related PTSD symptoms to mitigate the short- and long-term negative impacts after a traumatic event. When victims of SA receive optimal mental health treatments, our communities benefit as victims heal and recover.

Comparative effectiveness of psychological interventions for treating the psychological consequences of sexual abuse in children and adolescents: a network meta-analysis

BACKGROUND

Following sexual abuse, children and young people may develop a range of psychological problems, including anxiety, depression, post-traumatic stress disorder (PTSD), and a range of behaviour problems. Those working with children and young people experiencing these problems may use one or more of a range of psychological approaches.

OBJECTIVES

To assess the relative effectiveness of psychological interventions compared to other treatments or no treatment controls, to overcome psychological consequences of sexual abuse in children and young people up to 18 years of age. Secondary objectives To rank psychotherapies according to their effectiveness. To compare different 'doses' of the same intervention.

SEARCH METHODS

In November 2022 we searched CENTRAL, MEDLINE, Embase, PsycINFO, 12 other databases and two trials registers. We reviewed the reference lists of included studies, alongside other work in the field, and communicated with the authors of included studies.

SELECTION CRITERIA

We included randomised controlled trials comparing psychological interventions for sexually abused children and young people up to 18 years old with other treatments or no treatments. Interventions included: cognitive behavioural therapy (CBT), psychodynamic therapy, family therapy, child centred therapy (CCT), and eye movement desensitisation and reprocessing (EMDR). We included both individual and group formats.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies, extracted data and assessed the risk of bias for our primary outcomes (psychological distress/mental health, behaviour, social functioning, relationships with family and others) and secondary outcomes (substance misuse, delinquency, resilience, carer distress and efficacy). We considered the effects of the interventions on all outcomes at post-treatment, six months follow-up and 12 months follow-up. For each outcome and time point with sufficient data, we performed random-effects network and pairwise meta-analyses to determine an overall effect estimate for each possible pair of therapies. Where meta-analysis was not possible, we report the summaries from single studies. Due to the low number of studies in each network, we did not attempt to determine the probabilities of each treatment being the most effective relative to the others for each outcome at each time point. We rated the certainty of evidence with GRADE for each outcome.

MAIN RESULTS

We included 22 studies (1478 participants) in this review. Most of the participants were female (range: 52% to 100%), and were mainly white. Limited information was provided on socioeconomic status of participants. Seventeen studies were conducted in North America, with the remaining studies conducted in the UK (N = 2), Iran (N = 1), Australia (N = 1) and Democratic Republic of Congo (N = 1). CBT was explored in 14 studies and CCT in eight studies; psychodynamic therapy, family therapy and EMDR were each explored in two studies. Management as usual (MAU) was the comparator in three studies and a waiting list was the comparator in five studies. For all outcomes, comparisons were informed by low numbers of studies (one to three per comparison), sample sizes were small (median = 52, range 11 to 229) and networks were poorly connected. Our estimates were all imprecise and uncertain. Primary outcomes At post-treatment, network meta-analysis (NMA) was possible for measures of psychological distress and behaviour, but not for social functioning. Relative to MAU, there was very low certainty evidence that CCT involving parent and child reduced PTSD (standardised mean difference (SMD) -0.87, 95% confidence intervals (CI) -1.64 to -0.10), and CBT with only the child reduced PTSD symptoms (SMD -0.96, 95% CI -1.72 to -0.20). There was no clear evidence of an effect of any therapy relative to MAU for other primary outcomes or at any other time point. Secondary outcomes Compared to MAU, there was very low certainty evidence that, at post-treatment, CBT delivered to the child and the carer might reduce parents' emotional reactions (SMD -6.95, 95% CI -10.11 to -3.80), and that CCT might reduce parents' stress. However, there is high uncertainty in these effect estimates and both comparisons were informed only by one study. There was no evidence that the other therapies improved any other secondary outcome. We attributed very low levels of confidence for all NMA and pairwise estimates for the following reasons. Reporting limitations resulted in judgements of 'unclear' to 'high' risk of bias in relation to selection, detection, performance, attrition and reporting bias; the effect estimates we derived were imprecise, and small or close to no change; our networks were underpowered due to the low number of studies informing them; and whilst studies were broadly comparable with regard to settings, the use of a manual, the training of the therapists, the duration of treatment and number of sessions offered, there was considerable variability in the age of participants and the format in which the interventions were delivered (individual or group).

AUTHORS' CONCLUSIONS

There was weak evidence that both CCT (delivered to child and carer) and CBT (delivered to the child) might reduce PTSD symptoms at post-treatment. However, the effect estimates are uncertain and imprecise. For the remaining outcomes examined, none of the estimates suggested that any of the interventions reduced symptoms compared to management as usual. Weaknesses in the evidence base include the dearth of evidence from low- and middle-income countries. Further, not all interventions have been evaluated to the same extent, and there is little evidence regarding the effectiveness of interventions for male participants or those from different ethnicities. In 18 studies, the age ranges of participants ranged from 4 to 16 years old or 5 to 17 years old. This may have influenced the way in which the interventions were delivered, received, and consequently influenced outcomes. Many of the included studies evaluated interventions that were developed by members of the research team. In others, developers were involved in monitoring the delivery of the treatment. It remains the case that evaluations conducted by independent research teams are needed to reduce the potential for investigator bias. Studies addressing these gaps would help to establish the relative effectiveness of interventions currently used with this vulnerable population.

Group Therapy for Survivors of Adult Sexual Assault: A Scoping Review

Across the world, women experience significant rates of sexual assault and there is a need to strengthen support services offered to survivors. Group therapy could provide an important addition to services that support healing and growth; however, the effectiveness of group therapy interventions with survivors of adult sexual assault is not well understood and clearer insights into designing and running group therapy interventions require further exploration. This review synthesizes literature exploring group therapy for survivors of adult sexual assault to inform future interventions and research implementing group therapy. A systematic approach was used to gather literature describing and evaluating group therapy interventions with survivors of adult sexual assault. Of the initial 466 articles identified through a comprehensive search strategy including database and hand searches, 32 met the inclusion criteria by describing a group therapy intervention conducted with survivors of adult sexual assault. A thematic approach to analysis was conducted to synthesize and collate the literature. Findings explore potentially useful strategies and characteristics of group therapy with survivors of adult sexual assault and make recommendations for the design and evaluation of future interventions. Group therapy has potential as a valuable support service provided to survivors but further rigorous research and evaluations are required to better capture outcomes and understand how to design and implement effective interventions.

Measures of depression, generalized anxiety, and posttraumatic stress disorders amongst Yazidi female survivors of ISIS slavery and violence

BACKGROUND

In 2014 the Islamic State of Iraq and Syria (ISIS) undertook a systematic and deliberate campaign against minority groups and non-Sunni Muslim communities. Amongst some of the greatest atrocities were those targeted towards Yazidi communities and in particular their women. The mental health outcomes of those women held in captivity requires investigation. This study sought to examine and compare levels of general psychological distress, depression, generalized anxiety, posttraumatic stress disorder (PTSD) and self-reported suicidal thoughts and behaviors amongst Yazidi women held in captivity compared with those without such experiences.

METHOD

Between January to May 2019, a total 348 Yazidi women located in internal displaced person (IDP) camps were interviewed. Of these 348, 139 females were survivors of ISIS captivity. Measures used included Kessler Psychological Distress Scale (K10), Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder (GAD-7), and Harvard Trauma Questionnaire part IV (HTQ part IV).

RESULTS

Formerly enslaved Yazidi females showed a significantly higher prevalence of severe mental distress (97.1%; P < 0.001), more severe levels of depression (36.7%; P < 0.001) and general anxiety symptoms (37.4%; P < 0.001), greater rates of PTSD (90.6%; P < 0.001) and higher reported rates of suicidal ideation (38.1%; P < 0.001). Logistic regression analysis undertaken to examine the role of sociodemographic factors as predictors of the assessed mental health conditions. Amongst the formerly enslaved group, no such significance was found, however amongst the non-enslaved group, unemployment was found to statistically determine depression, generalized anxiety and PTSD. Specifically, women from the non-enslaved group who were unemployed were 2.5 times more likely to have depression, 3 times more likely to have generalized anxiety and 3.3 times more likely to have PTSD. Finally, amongst the non-enslaved group, those women with between 5 to 8 siblings were significantly less likely to have depression than those with fewer siblings.

CONCLUSION

Rates of distress and trauma related symptomology were significantly higher amongst those with history of enslavement. Sociodemographic factors and duration of enslavement do not seem to predict mental disorders among enslaved females.

The role of age and mode of delivery in the STEPS intervention: a longitudinal pilot-study in treatment of posttraumatic stress symptoms in Danish survivors of sexual assault

Background: The STEPS programme has been succesfully implemented as a group-based treatment of trauma symptoms after rape for adolescents. The STEPS intervention was translated from Dutch to Danish and offered to adults in addition to adolescents as well as an individual intervention in addition to a group-based intervention at a Danish Centre for Rape Victims through 2011 to 2014. The programme was translated from Dutch to Danish and expanded to adults in addition to adolescents as well as to an individual intervention in addition to a group-based intervention at a Danish Centre for Rape Victims through 2011 to 2014. Objective: The present study observes  development in trauma symptoms and ICD-11 diagnostic status during an adapted version of the intervention programme 'STEPS' for survivors of sexual assault. Methods: A prospective uncontrolled study was conducted, monitoring symptoms of posttraumatic stress and other trauma-related symptomatology before treatment, after treatment and at 6 and 12 months' follow up for 103 referrals receiving individual or group-based STEPS. Tentative diagnoses of posttraumatic stress disorder (PTSD) and complex PTSD were assigned to participants according to the ICD-11 to observe the development in diagnostic status across time, and multilevel modelling was used to assess the development of symptom severity and to assess the moderating effect of age-group and mode of delivery. Results: A loglinear function representing large and statistically significant decline in symptomatology over time provided the best fit for all measures of trauma-related symptomatology. The decline was not moderated by age-group or mode of intervention. Dropout rates were independent of mode of intervention and age. Conclusion: The adaption of the STEPS programme to adults and as an individual intervention is feasible and maintains effect sizes comparable to those observed in the original intervention. Further research using randomized controlled trials is needed to ascribe the observed effect to the STEPS programme.

Smaller hippocampal volume following sexual assault in women is associated with post-traumatic stress disorder

OBJECTIVE

Exposure to sexual assault is a significant risk factor to develop post-traumatic stress disorder (PTSD) in females. The early neurobiological changes leading to the development of PTSD remain understudied and unclear in this population.

METHODS

Participants were 27 adult females recruited within a month following exposure to sexual assault (T1) and 20 age-matched non-exposed controls. Among the victims, 10 participants met (PTSD+) and 15 did not meet (PTSD-) DSM-IV criteria for PTSD 6 months post-trauma (T2). At both visits, hippocampal and amygdala volumes were extracted from magnetic resonance imaging scans, and indices of total diurnal cortisol changes were derived from individual areas under the curve relative to the ground (AUCg). Measures at T1 were compared between groups at T1, measures at T2 between groups at T2, and measures at T1 between groups at T2.

RESULTS

At T1, victims had significantly smaller bilateral hippocampal volumes, but not AUCg, than controls. At T2, neither hippocampal volume nor AUCg significantly differed among the groups. However, the PTSD+ group had significantly smaller hippocampal volumes at T1 than the control group, but not compared to the PTSD- group.

CONCLUSIONS

This study indicates that having smaller hippocampal volumes is a risk factor to develop PTSD in females exposed to sexual assault.

Emotion regulation difficulties in traumatized youth: a meta-analysis and conceptual review

This article provides a quantitative and conceptual review of emotion regulation difficulties in trauma-exposed young people, and informs future directions in the field. Despite long-standing interest in the influence of emotion regulation difficulties on different internalizing and externalizing psychiatric disorders in childhood, several questions remain unresolved with respect to children and adolescents with PTSD (post-traumatic stress disorder). Meta-analytic data from adult victims suggest that emotion regulation problems are associated with PTSD, but this has never been studied in children and young people. We therefore provide a conceptual review of features related to the phenomenology, assessment, severity and treatment of emotion regulation difficulties in trauma-exposed children and young people. We combine this with a meta-analysis of published literature. We searched studies in Medline, PsychINFO, and Embase databases based on pre-selected criteria. Eight hundred and eighty-six papers were identified and 41 were included. We found that children and adolescents with a diagnosis of PTSD reported more emotion regulation difficulties than those who did not develop PTSD, and that the overall association between the two symptom dimensions was moderately strong. We identify a number of research priorities: the development of instruments to assess emotion regulation difficulties in children, the design of studies that describe its prevalence in young epidemiological traumatized samples, its predictive role in the onset, severity and persistence of post-traumatic symptoms, and its relevance as a moderator, outcome or treatment target for young survivors.
