PTSD and its treatment in people with intellectual disabilities: a review of the literature

EMDR treatment for people with intellectual disabilities: a systematic review about difficulties and adaptations

Introduction

People with intellectual disabilities (ID) are at increased risk for developing Post Traumatic Stress Disorder (PTSD). Emerging evidence indicates that Eye Movement Desensitization and Reprocessing (EMDR) therapy is feasible and potentially effective for this group. However, communication, cognition, stress regulation, and attachment difficulties may interfere with the EMDR process. Adaptation of the EMDR protocol seems therefore required for this population.

Aim

This review aims to systematically identify and categorize the difficulties in applying EMDR to people with ID and the adaptations made by therapists to overcome these challenges.

Methods

A literature search was performed in May 2023. Article selection was based on inclusion and exclusion criteria and quality appraisal.

Results

After screening, 13 articles remained for further review. The identified difficulties and adaptations were categorized into the three domains of adaptive functioning (i.e., conceptual, social, and practical functioning). Considerable difficulties in applying the EMDR protocol for this group were reported. The adaptations made by therapists to overcome these difficulties were highly variable. They could be divided into three main categories: adaptions in EMDR delivery (e.g., tuning to the developmental level of the client, simplifying language, decreasing pace), involvement of others (e.g., involving family or support staff during or in between sessions), and the therapeutic relationship (e.g., taking more time, supportive attitude).

Discussion

The variability of the number of mentioned difficulties and adaptations per study seems to be partly related to the specific EMDR protocol that was used. In particular, when the Shapiro adult protocol was administered, relatively more detailed difficulties and adaptations were described than in publications based on derived existing versions of an EMDR protocol for children and adolescents. A probable explanation is that already embedded modifications in these protocols facilitate the needed attunement to the client's level of functioning.

Practical implications

The authors of this review suggest that EMDR protocols for children and adolescents could be adapted for people with an intellectual disability. Further research should focus on the involvement of trusted others in EMDR therapy for people with ID and the therapeutic relationship from an attachment and relational-based perspective.

Family dynamics, trauma, and child-related characteristics: examining factors associated with co-occurring mental health problems in clinically-referred children with and without an intellectual (and developmental) disability

Psychiatric disorders are common in youth with intellectual and developmental disabilities. This is a vulnerable group of children whose behavioural problems often have more complicated care needs than other children, which can place a great deal of stress on their families. However, the association of family mental health issues, level of intellectual ability, and diagnostic co-morbidity in children is relatively under-studied. In the present study, we investigated the relationship among child diagnoses, family mental health problems, risk for self-injury, and disruption in care among children with (N = 517) and without (N = 517) intellectual and developmental disabilities. A negative binomial regression showed that mental health problems in multiple family members, self-injurious behaviour, and self-reported abuse/trauma was related to greater likelihood of provisional diagnoses of co-occurring psychiatric disorders in both a clinically referred sample and a sample with IDD. Implications for care-planning are discussed.

Consensus recommendations on mental health issues in Phelan-McDermid syndrome

Phelan-McDermid syndrome is a rare genetic condition caused by a deletion encompassing the 22q13.3 region or a pathogenic variant of the gene SHANK3. The clinical presentation is variable, but main characteristics include global developmental delay/intellectual disability (ID), marked speech impairment or delay, along with other features like hypotonia and somatic or psychiatric comorbidities. This publication delineates mental health, developmental and behavioural themes across the lifetime of individuals with PMS as informed by parents/caregivers, experts, and other key professionals involved in PMS care. We put forward several recommendations based on the available literature concerning mental health and behaviour in PMS. Additionally, this article aims to improve our awareness of the importance of considering developmental level of the individual with PMS when assessing mental health and behavioural issues. Understanding how the discrepancy between developmental level and chronological age may impact concerning behaviours offers insight into the meaning of those behaviours and informs care for individuals with PMS, enabling clinicians to address unmet (mental health) care needs and improve quality of life.

Evaluation of an adapted version of the International Trauma Questionnaire for use by people with intellectual disabilities

AIMS

The International Trauma Questionnaire (ITQ) is a novel assessment instrument that is aligned to the ICD-11 diagnoses of post-traumatic stress disorder (PTSD) and complex PTSD (CPTSD). The purpose of this study was to develop and evaluate an adapted version of the ITQ suitable for use by people with intellectual disabilities.

METHODS

The ITQ-ID follows the original ITQ, using wording developed in collaboration with a focus group of people with intellectual disabilities The ITQ-ID was administered to 40 people with intellectual disabilities recruited from learning disability forensic and community settings, alongside a Trauma Information Form and the Impact of Event Scale-Intellectual Disabilities (IES-IDs).

RESULTS

Most participants reported multiple traumatizing events. Around half of the participants met strict criteria for a diagnosis of PTSD, and around three quarters met looser criteria. Depending on definitions, between 66% and 93% of those who met criteria for PTSD also met criteria for a diagnosis of CPTSD. The ITQ-ID showed a single-component structure, with very good-to-excellent internal consistency, excellent test-retest reliability, and evidence of concurrent, discriminant, and content validity.

SIGNIFICANCE

The results support the potential of the ITQ-ID for assessment of PTSD and CPTSD in people with intellectual disabilities in both clinical and research contexts and highlight the need for further validation work.

Risk Factors for Positive Post-Traumatic Stress Disorder Screening and Associated Outcomes in Children Surviving Acute Respiratory Failure: A Secondary Analysis of the Randomized Evaluation of Sedation Titration for Respiratory Failure Clinical Trial

OBJECTIVES

To identify risk factors and outcomes associated with a positive post-traumatic stress disorder (PTSD) screen following pediatric acute respiratory failure treated with invasive mechanical ventilation.

DESIGN

Nonprespecified secondary analysis of a randomized clinical trial.

SETTING

Thirty-one U.S. PICUs.

PATIENTS

Children in the Randomized Evaluation of Sedation Titration for Respiratory Failure (RESTORE) trial (NCT00814099, ClinicalTrials.gov ) over 8 years old who completed PTSD screening 6 months after discharge.

INTERVENTIONS

RESTORE sites were randomized to a targeted, nurse-directed sedation strategy versus usual care.

MEASUREMENTS AND MAIN RESULTS

PTSD screening was completed by 102 subjects using the Child Post-Traumatic Stress Disorder Symptom Scale; a score of greater than or equal to 11 was considered screening positive for PTSD. Cognitive status was categorized using Pediatric Cerebral Performance Category; health-related quality of life (HRQL) was evaluated using child-reported Pediatric Quality of Life Inventory, Version 4.0. Thirty-one children (30%) screened positive for PTSD. Children with a positive screen endorsed symptoms in all categories: reexperiencing, avoidance, and hyperarousal. Most endorsed that symptoms interfered with schoolwork ( n = 18, 58%) and happiness ( n = 17, 55%). Screening positive was not associated with RESTORE treatment group. In a multivariable logistic model adjusting for age, sex, and treatment group, screening positive was independently associated with lower median income in the family's residential zip code (compared with income ≥ $80,000; income < $40,000 odds ratio [OR], 32.8; 95% CI, 2.3-458.1 and $40,000-$79,999 OR, 15.6; 95% CI, 1.3-182.8), renal dysfunction (OR 5.3, 95% CI 1.7-16.7), and clinically significant pain in the PICU (OR, 8.3; 95% CI, 1.9-35.7). Children with a positive screen experienced decline in cognitive function and impaired HRQL more frequently than children with a negative screen.

CONCLUSIONS

Screening positive for PTSD is common among children following acute respiratory failure and is associated with lower HRQL and decline in cognitive function. Routine PTSD screening may be warranted to optimize recovery.

Trauma-Informed Care for Individuals with Intellectual and Developmental Disabilities: From Disparity to Policies for Effective Action

People with intellectual disabilities (ID) are an often overlooked minority population. They experience significant health disparities and a high risk of exposure to traumatic events that can lead to stress-related disorders. Access to effective treatments for stress-related disorders is limited for people with ID due to a lack of appropriate assessments and common communication deficits. We discuss and analyze four factors that have led to these disparities: (1) historical segregation; (2) society's response to identification of trauma in vulnerable populations; (3) lack of accessible assessments and treatments for stress disorders in people with ID; and (4) communication deficits common in people with ID. Based on this analysis, we suggest behavior analysts advocate for policy development that would (1) increase acknowledgement of trauma in people with ID and mandate sharing of information about trauma across providers; (2) require observable and measurable goals be included in the assessment and treatment of trauma-related behavior change; and (3) increase funding for services and research in this area.

Characteristics and Prevalence of Lifetime Sexual Victimization Among a Sample of Men and Women with Intellectual Disabilities

This study examines the prevalence and characteristics of sexual victimization experiences suffered by people with intellectual disabilities (ID). The sample consisted of 260 adults with an ID diagnosis (154 men and 106 women), ranging in age from 20 to 71 years (M = 41.69, SD = 12.05). The results showed that 35% of the sample had been sexually victimized at some point in their life. Being a woman, being declared legally incapable, and having comorbid mental health diagnoses were the most relevant characteristics of sexual victims with ID. Fondling was the most reported victimization, and rape showed the greatest gender differences, with a higher risk for women with ID of being raped compared to their male counterparts (odds ratio = 4.28, p < .05). The offender was generally a known male adult, and the percentage of incidents reported to the authorities was very low (7.4%). The psychological consequences of abuse were general distress, anxiety, and depressive symptomatology. Intervention and prevention programs targeting this population, as well as the training of professionals and caregivers, are essential to deal with sexual victimization and to protect and ensure the quality of life of people with ID.

Prevalence of Secondary Traumatic Stress Among Direct Support Professionals in Intellectual and Developmental Disabilities Field

Direct support professionals (DSPs) are deemed by existing literature as vital support to persons with intellectual or developmental disabilities (IDD). They may be exposed to the traumatic experiences of people with IDD with potential psychological implications. Secondary traumatic stress (STS) has been studied among related professionals across human services, but little is known among DSPs. The current study examines the prevalence of STS in a sample of DSPs. The results suggested that DSPs are exposed to traumatic experiences, and exposure to a greater number of traumatized clients is significantly correlated with symptoms of STS. At least 12.4% of DSPs in this sample met the diagnostic criteria for experiencing post-traumatic stress disorder (PTSD) symptoms. Also, results suggest STS differences in DSPs based on demographics.

Post-traumatic stress in adults with 22q11.2 deletion syndrome

22q11.2 deletion syndrome (22q11.2DS) is associated with an elevated genetic risk of several psychiatric disorders. However, the prevalence of post-traumatic stress disorder (PTSD) in individuals with 22q11.2DS has been reported to be only 0.9%; this is lower than that of the general population (3.9%). We explored the occurrence of PTSD and traumatic events in a Dutch cohort of 112 adults with 22q11.2DS, and found PTSD in 8.0%, traumatic events in 20.5% and trauma-focused treatment in 17.9% of patients. Our novel findings suggest that PTSD may be underdiagnosed in individuals with 22q11.2DS. Clinicians and other caregivers should be alert to trauma in this population in order to enable treatment and minimise psychiatric burden.

Mental health problems in children with intellectual disability

Intellectual disability ranks in the top ten causes of disease burden globally and is the top cause in children younger than 5 years. 2-3% of children have an intellectual disability, and about 15% of children present with differences consistent with an intellectual disability (ie, global developmental delay and borderline intellectual functioning). In this Review, we discuss the prevalence of mental health problems, interventions to address these, and issues of access to treatment and services. Where possible, we take a global perspective, given most children with intellectual disability live in low-income and middle-income countries. Approximately 40% of children with intellectual disability present with a diagnosable mental disorder, a rate that is at least double that in children without intellectual disability. Most risk factors for poor mental health and barriers to accessing support are not unique to people with intellectual disability. With proportionate universalism as the guiding principle for reducing poor mental health at scale, we discuss four directions for addressing the mental health inequity in intellectual disability.

A Systematic Review of Treatment Interventions for Individuals With Intellectual Disability and Trauma Symptoms: A Review of the Recent Literature

Individuals with intellectual disabilities (IDs) are at increased susceptibility to adverse life experiences and trauma sequelae. There is a disparate range of therapeutic interventions for post-traumatic stress disorder (PTSD) and associated symptoms. This systematic review aimed to appraise the effectiveness of both cognitive behavioral therapy (CBT) and eye movement desensitization and reprocessing (EMDR) for PTSD and associated symptoms for both adults and children with mild, moderate, or severe intellectual delay. A systematic search, in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, of the PsychInfo, PubMed, Cochrane Database of Systematic Reviews, and MEDLINE databases were performed, and all relevant articles published between 2010 and March 2020 were included. A total of 11 articles were included, eight that focused on EMDR and three on CBT. The methodological quality of many of these articles was generally weak. Tentative findings suggest that EMDR and CBT are both acceptable and feasible treatment options among adults and children with varying levels of intellectual delay, but no firm conclusions can be drawn regarding effectiveness due to small sample sizes, lack of standardized assessment, and a paucity of methodological rigorous treatment designs. This review highlights the continued use of therapeutic approaches with clients presenting with IDs and PTSD. It adds to the extant literature by providing an expansive and broad overview of the current effectiveness of both EMDR and CBT. Further high-quality research is needed to provide more conclusive findings regarding treatment effectiveness and modifications to treatment needed with this population.

Victimization history in female forensic psychiatric patients with intellectual disabilities: Results from a Dutch multicenter comparative study

BACKGROUND

Victimization is highly prevalent in individuals with mild intellectual disability (MID) or borderline intellectual functioning (BIF) and is an important risk factor for mental health problems and violent behavior. Not much is known, however, about victimization history in women with MID-BIF admitted to forensic mental health care.

AIMS

The aim of this multicenter study is to gain insight into victimization histories and mental health problems of female forensic psychiatric patients with MID-BIF.

METHODS

File data were analyzed of 126 women with MID-BIF who have been admitted to one of five Dutch forensic psychiatric hospitals between 1990 and 2014 and compared to data of 76 female patients with average or above intellectual functioning and to a matched sample of 31 male patients with MID-BIF.

RESULTS

All forensic patients had high rates of victimization, but women with MID-BIF showed an even higher prevalence of victimization during both childhood and adulthood and more complex psychopathology compared to female patients without MID-BIF. Compared to male forensic patients with MID-BIF, women with MID-BIF were more often victim of sexual abuse during childhood. During adulthood, the victimization rate in these women was more than three times higher than in men.

CONCLUSIONS

Victimization is a salient factor in female forensic patients with MID-BIF and more gender-responsive trauma-focused treatment is needed.

Trauma-informed care in the context of intellectual and developmental disability services: Perceptions of service providers

Traumatic life events have pervasive impacts on health and well-being. A growing body of literature shows that people with intellectual and developmental disabilities are disproportionately impacted by trauma. Trauma-informed care (TIC) is a philosophy of service provision that is committed to preventing traumatization and re-traumatization and promoting healing. This study explores the perceptions of 130 leaders in the field of intellectual and developmental disabilities services on the adoption and practice of TIC through the analysis of quantitative data. Results indicated a disconnect between the level of TIC integration and perceptions detailing how well organizations are currently performing in aspects of TIC. Barriers to TIC included high staff turnover, lack of accessible mental health providers, lack of affordable training, stigma, and restrictive funding structures. Implications and recommendations for service organizations and educators are provided.

Psychological eHealth interventions for people with intellectual disabilities: A scoping review

BACKGROUND

The use of eHealth, which has accelerated in the wake of the COVID-19 pandemic, could contribute to the access to tailor-made psychological interventions for people with intellectual disabilities.

METHOD

A scoping review was conducted on peer-reviewed studies between 1996-2019.

RESULTS

Thirty-three studies reported on the use of psychological eHealth interventions focused on mental health problems and/or challenging behaviour. The vast majority of these studies reported on interventions that were delivered at the individual level. The context in which these interventions were delivered varied, primarily ranging from the home setting to residential settings, as well as day or activity centres and schools. The studies described various types of interventions: telehealth interventions, computerized cognitive behavioural therapy, and interventions focused on (social) learning principles targeting challenging behaviour.

CONCLUSIONS

eHealth provides new opportunities for both therapists and lay-therapists to deliver psychological interventions. Future studies should focus on the effectiveness of psychological eHealth interventions.

“Mutig werden kann ich lernen”: Kognitive Verhaltenstherapie bei ausgeprägter Angstsymptomatik, Entwicklungsstörung und Intelligenzminderung

<b><i>Hintergrund:</i></b> Die psychotherapeutische Behandlung von Kindern und Jugendlichen mit geistiger Behinderung unterliegt einer Vielzahl von Barrieren. <b><i>Fallbericht:</i></b> Der hier vorgestellte Behandlungsfall illustriert die erfolgreiche Anwendung kognitiver Verhaltenstherapie bei einem 10-jährigen Mädchen bei Entwicklungsstörung und Intelligenzminderung. Nach einer medizinisch notwendigen Untersuchung entstanden ausgeprägte Angstsymptome und Verhaltensprobleme. Infolge einer bekannten Epilepsie war der Einsatz expositionsbasierter Techniken fraglich. Die kognitive Verhaltenstherapie umfasste 64 Behandlungseinheiten. Das Vorgehen zur Selbstbeobachtung, Rationalvermittlung und Angstbewältigung war stark handlungsbezogen und wenig kognitiv orientiert und fand im häuslichen Setting mit Einbezug der Familienmitglieder statt. Nachfolgend wurden – auch aufgrund der zunehmenden Reifung des Kindes – kognitiv anspruchsvollere Techniken eingesetzt. Zur 38. Behandlungseinheit wurden zuvor angstbesetzte Situationen dem Entwicklungsstand angemessen und selbstständig bewältigt. Eine nachfolgende medizinische Untersuchung ähnlich der Auslösesituation wurde therapeutisch vorbereitet und sicher bewältigt. Zu Behandlungsende waren die Alltagskompetenzen maßgeblich erweitert. <b><i>Schlussfolgerungen:</i></b> Entgegen der Vorannahmen bedurfte es nur weniger Anpassungen an das Setting und die Behandlungstechniken im Vergleich zum Vorgehen bei ähnlicher Symptomatik ohne geistige Behinderung. Durch die psychotherapeutische Behandlung konnte kurz- und langfristig eine Manifestation (Eskalation) von weiterem Problemverhalten verhindert werden. Das Erkennen und die Auseinandersetzung mit dem “Anderssein” infolge der geistigen Behinderung und verfügbarer Alltagskompetenzen bergen Entwicklungsrisiken und -chancen, die durch eine psychotherapeutische Begleitung gut bewältigt werden können.

Trauma experiences of people with an intellectual disability and their implications: A scoping review

BACKGROUND

People with an intellectual disability are more vulnerable to psychological trauma compared with the general population. The aim of this scoping review was to identify the current status of the literature on trauma that is specific to the experiences of adults with an intellectual disability, living in community settings.

METHODS

A scoping review was conducted using the Arksey and O'Malley (International Journal of Social Research Methodology, 2005, 8, 19) framework. Forty-one international papers were reviewed spanning 2000-2020, and their quality assessed using the MMAT.

FINDINGS

(1) Aggressive behaviours can be symptoms of trauma, (2) there are appropriate assessment tools for the impact of trauma, (3) evidence-based interventions for trauma may be effective, and (4) factors associated with disability can be experienced as traumatic.

CONCLUSION

There is a growing body of literature highlighting assessment needs and potential interventions for people with an intellectual disability who have experienced psychological trauma. Further research is needed to develop trauma-informed pathways.

Heightened risk of posttraumatic stress disorder in adults with autism spectrum disorder: The role of cumulative trauma and memory deficits

BACKGROUND

Individuals with Autism Spectrum Disorder (ASD) are known to be at increased risk of exposure to traumas such as maltreatment and abuse, however less is known about possible susceptibility towards the development of Posttraumatic Stress Disorder (PTSD) and associated risk factors.

AIMS

This study investigated the rates of trauma exposure and PTSD, and the role of cumulative trauma exposure and memory as risk factors for PTSD in adults who self-reported having received an ASD diagnosis, compared to a typically developing (TD) comparison group.

METHODS

Questionnaires assessing self-reported frequency of trauma exposure (LEC), PTSD symptomology (PCL-S) and memory (EMQ- R and BRIEF-A) were completed online by 38 ASD adults and 44 TD adults.

RESULTS

Rates of trauma exposure and PTSD symptomatology were significantly higher in the ASD group, compared to the TD group, with deficits in working memory and everyday memory mediating this association. Interestingly, a cumulative effect of trauma exposure on PTSD symptom severity was only found in the ASD group.

CONCLUSIONS

High rates of trauma and probable PTSD in ASD adults highlight the importance of routine screening. Cumulative trauma exposure and memory deficits may act to increase risk of PTSD in ASD; longitudinal research is called for.

Caring for the Most Vulnerable: A Model for Managing Maladaptive Behavior in Children with Mental Special Needs During the COVID-19 Pandemic

Background: This article presents the results of a comprehensive national model developed for managing maladaptive behaviors (MBs) in children with mental special needs (CMSNs) during the coronavirus disease 2019 (COVID-19) pandemic that combines telehealth-based Applied Behavioral Analyses, psychiatric interventions, and support from local psychosocial teams. This study aims to determine the effectiveness of a system that combined telehealth applications with local psychosocial support teams, allowing services from video calls to emergency interventions. Materials and Methods: The system combines the telehealth applications with the services from local psychosocial intervention teams. In addition to system records covering sociodemographic variables and initial complaints, a telephone survey questioning the effectiveness and satisfaction of the system was used as the main outcome. Results: In total, 347 individuals used the system with mothers constituting the majority of applicants (88.7%, n = 332). The overall satisfaction of the system was 8.8/10. In terms of effectiveness, 63.3% (n = 237) of caregivers reported an improvement in the reason of application. Counselors decided on a need for follow-up visits for 36.6% (n = 137) of applications. A referral to a psychiatrist was asked for 40 patients (10.6%). Discussion: To our best knowledge, this is the first study presenting a model for managing MBs of CMSNs during the COVID-19 outbreak. In general, therefore, it seems that there is a need for unique systems to handle behavioral problems of CMSNs. Conclusions: The findings of this study suggest that it is possible to establish an integrative multistep multidisciplinary telehealth-based approach in a short while.

The association between challenging behaviour and symptoms of post-traumatic stress disorder in people with intellectual disabilities: a Bayesian mediation analysis approach

BACKGROUND

A preponderance of behavioural symptoms is assumed to be the main difference in the manifestation of symptoms of post-traumatic stress disorder (PTSD) in people with intellectual disability (ID). However, no study so far has assessed the relationship between challenging behaviour (CB) and PTSD. The present study aims to explore this relationship by exploring whether CB is directly related to trauma exposure or whether this relationship is mediated through core symptoms of PTSD.

METHODS

Trauma exposure and current symptoms of PTSD were assessed in 43 adults with mild to moderate ID. Parallel versions were administered to 43 caregivers, including the Aberrant Behaviour Checklist to measure CB. Bayesian mediation analyses were conducted using self-rated and informant-rated data.

RESULTS

The self-report data showed no associations of CB with trauma exposure or PTSD symptoms. The association between informant-rated trauma exposure and irritability was mediated by severity and frequency of PTSD symptoms. The associations between informant-reported trauma exposure and the Aberrant Behaviour Checklist subscales hyperactivity and inappropriate speech were mediated by PTSD symptom severity.

CONCLUSIONS

The relationship between trauma exposure and CB was mediated by PTSD symptoms. PTSD core symptoms should be considered as underlying causes of CB, highlighting the necessity to explore trauma biography and symptoms of PTSD. The improvement of self-report assessment in people with ID is an important task for future studies.

Compassion-focused therapy for trauma in people with intellectual disabilities: A conceptual review

Trauma exposure and post-traumatic stress disorder are more prevalent in people with intellectual disabilities (PWID) than in the general population, yet the evidence base for trauma interventions in this population is sparse. Compassion-focused therapy (CFT) may be particularly well-suited to PWID for a number of reasons, including its adaptability to different developmental levels. PWID are more likely to have issues with self-relating (e.g. shame and self-criticism) and attachment than the general population, two issues that are compounded by trauma and which CFT explicitly seeks to address. Furthermore, compassion-focused approaches emphasize cultivating a sense of safeness while empowering people to make behavioural changes; this is particularly pertinent to PWID who have been traumatized and may feel unsafe and disempowered. An overview of CFT and its application to trauma are given, as well as some case studies using CFT with PWID.

Applicability of the post-traumatic stress disorder gate criterion in people with mild to moderate intellectual disabilities: Do additional adverse events impact current symptoms of Post Traumatic Stress Disorder in people with intellectual disabilities?

Background

Diagnostic manuals provide a strict definition of the PTSD gate criterion. Research on the adequacy of this definition in people with intellectual disabilities is lacking. This study aims to test the adequacy of the gate criterion for this population.

Method

Fourty nine adults with mild to moderate intellectual disabilities and 43 caregivers were questioned. Traumatic events included in the gate criterion definition and adverse events going beyond it were assessed. It was tested whether adverse events affect symptoms of PTSD additionally to traumatic events.

Results

The current data showed ambiguous findings in self‐ and informant report. Informant data suggested an additional impact of adverse events on PTSD symptoms. Self‐report data suggested the contrary.

Conclusion

Adverse events seem to have an impact on externalizing behavioural symptoms, such as hyperarousal. Self‐report assessment of more specific, intrapsychic PTSD symptoms, such as intrusions and avoidance, should be addressed in future studies.

Sex and genes, part 2: A biopsychosocial approach to assess and treat challenging sexual behavior in persons with intellectual disabilities including fragile X syndrome and 22q11.2 deletion syndrome

Individuals with intellectual disabilities (IDs) - and specifically those with genetic disorders - are more prone to medical and psychological challenges that affect their sexual development, experiences, and fertility. In this review paper we first provide an overview of the biopsychosocial (BPS) model and then explain how the model can guide and improve the assessment and treatment of challenging sexual behaviors by persons with IDs. We discuss two genetic conditions - fragile X syndrome and 22q11.2 deletion syndrome - in case studies, showing how the BPS model can be used to assess and treat the sexual problems of individuals with various types of ID. We conclude with BPS-formulated treatment considerations in three key domains: biomedical treatment (e.g., medication side effects; stopping or changing medications), psychological treatment (e.g., providing psychological therapies), and socio-environmental interventions (e.g., providing socio-sexual education and staff training). Together, these treatment interventions can aid clinicians to prevent and/or treat problematic sexual behaviors of people with IDs.

Social reactions to disclosure of sexual violence in female adults with mild to moderate intellectual disabilities: a qualitative analysis of four cases

Socio-interpersonal factors have a strong potential to protect individuals against pathological processing of traumatic events. While perceived social support has emerged as an important protective factor, this effect has not been replicated in people with intellectual disabilities (ID). One reason for this might be that the relevance of socio-interpersonal factors differs in people with ID: Social support may be associated with more stress due to a generally high dependency on sometimes unwanted support. An exploration of the role of posttraumatic, socio-interpersonal factors for people with ID is therefore necessary in order to provide adequate support. The current study aims to explore the subjective perception of social reactions to disclosure of sexual violence in four women with mild to moderate ID. The study was conducted in Austria. The women were interviewed about their perception of received social reactions as benevolent or harmful, their emotional response, and whether they perceived being treated differently due to their ID diagnosis. The interviews were analysed using qualitative content analysis. First, the interviews were coded inductively, and social reactions were then deductively assigned to three categories that were derived from general research: positive reactions, unsupportive acknowledgement, turning against. Findings on the perception of social reactions were in line with findings from the general population. Overall, participants reported that they did not feel that they were treated any differently from persons without disabilities. However, the social reactions they received included unjustified social reactions, such as perpetrators not being held accountable. A possible explanation may be a habituation and internalisation of negative societal attitudes towards women with ID. Empowerment programmes and barrier-free structural support for women with ID following trauma exposure should be improved.

Trauma and Autism Spectrum Disorder: Review, Proposed Treatment Adaptations and Future Directions

Empirical investigations of trauma and post-traumatic stress disorder (PTSD) in individuals with autism spectrum disorder (ASD) are lacking despite indications of increased risk for exposure to potentially traumatic events in this population. Research on the treatment of traumatic stress psychopathology in ASD is even more limited and suggests a critical need for guidance in the area of ASD-specific treatment adaptations. The current paper provides preliminary recommendations for adapting current evidenced-based, trauma-specific interventions, specifically trauma-focused cognitive behavioral therapy (TF-CBT), for individuals with ASD based on well-established and evidence-based practices for working with this population. These adaptations highlight the need to incorporate treatment goals related to ASD core symptoms and associated characteristics during treatment targeting traumatic stress symptoms. Future directions are discussed, including the development of instruments measuring trauma reactions in ASD, empirical investigations of modified trauma interventions for children with ASD to evaluate effectiveness, and collaboration between professionals specializing in ASD and trauma/PTSD to advance research and facilitate effective care for this community.

Clinical characteristics of individuals with intellectual disability who have experienced sexual abuse. An overview of the literature

BACKGROUND

Sexual abuse in individuals with average IQ or above is associated with a wide range of behavioural, psychological and body-related characteristics. It is unknown whether individuals with intellectual disability (ID) and a history of sexual abuse suffer from similar clinical characteristics.

OBJECTIVE

The aim of the review is to provide an overview of the literature on the clinical characteristics of individuals with ID who have experienced sexual abuse.

METHOD

PubMed, Embase, PsycInfo, CINAHL, Cochrane Library and Web of Sciences were searched for relevant publications using terms related to concepts of "intellectual disability" and "sexual abuse". Two independent reviewers screened and selected articles for inclusion in the study, resulting in seven studies.

RESULTS

The studies mostly reported behavioural and psychological characteristics such as aggression, self-injury, or posttraumatic stress, anxiety or depressive symptoms associated with sexual abuse in individuals with ID. None mentioned body-related characteristics.

CONCLUSIONS

Similar to individuals with average IQ or above, sexual abuse in individuals with ID is associated with a broad range of behavioural and psychological characteristics. Conduct disorders, self-injury, inappropriate sexualised talk and poor feelings of personal safety seem to be more indicative for the ID population. Anxiety, depression and PTSD are prevalent in individuals with and without ID who both have experienced sexual abuse. Whether individuals with ID experience body-related characteristics is unclear.

“One does not forget, it all comes back”: elderly people with intellectual disability review adversities and stress-protection in their lives

Purpose

People with intellectual disability are reported to encounter many negative life events during their increasingly long lives. In the absence of protective elements, these may cause toxic stress and trauma. Given the reported negative effects of such adverse events on their quality of life (QoL), the perspective of older people with intellectual disability themselves may be of relevance. The paper aims to discuss these issues.

Design/methodology/approach

The authors questioned nine participants with mild intellectual disability, aged 61–88 years old, in four 90-min focus group sessions and thematically analysed the data.

Findings

Many recent and bygone negative life events still weighed heavily on the participants. Negative interactions, experiences of loss, lack of control and awareness of one’s disability caused stress. Their emotional response contrasted with their contentment, compliance and resilience. Having (had) good relationships, having learnt coping skills, remaining active, talking about past experiences and feeling free of pain, safe, well supported, capable, respected and involved seemed to heighten resilience and protect participants from toxic stress.

Research limitations/implications

Monitoring and preventing adverse (childhood) experiences, supporting active/emotional coping strategies, psychotherapy and life story work may facilitate coping with negative events and enhance QoL of elderly people with intellectual disability.

Originality/value

Elderly people with mild intellectual disability run a higher risk of experiencing (early) adverse events in life. They are very capable of talking about their experiences, QoL, and the support they need. Focus groups were a reliable method to capture their insights.

Physical exercise ameliorates psychiatric disorders and cognitive dysfunctions by hippocampal mitochondrial function and neuroplasticity in post-traumatic stress disorder

Post-traumatic stress disorder (PTSD) is a stress-related condition that can be triggered by witnessing or experiencing a life-threatening event, such as a war, natural disaster, terrorist attack, major accident, or assault. PTSD is caused by dysfunction of the hippocampus and causes problems associated with brain functioning, such as anxiety, depression, and cognitive impairment. Exercise is known to have a positive effect on brain function, especially in the hippocampus. In this study, we investigated the effect of aerobic exercise on mitochondrial function and neuroplasticity in the hippocampus as well as behavioral changes in animal models of PTSD. Exposure to severe stress resulted in mitochondrial dysfunction in the hippocampus, including impaired Ca²⁺ homeostasis, an increase in reactive oxygen species such as H₂O₂, a decrease in the O₂ respiration rate, and overexpression of membrane permeability transition pore-related proteins, including voltage-dependent anion channel, adenine nucleotide translocase, and cyclophilin-D. Exposure to extreme stress also decreased neuroplasticity by increasing apoptosis and decreasing the brain-derived neurotrophic factor level and neurogenesis, resulting in increased anxiety, depression, and cognitive impairment. The impairments in mitochondrial function and neuroplasticity in the hippocampus, as well as anxiety, depression, and cognitive impairment, were all improved by exercise. Exercise-induced improvement of the brain-derived neurotrophic factor level in particular might alter mitochondrial function, neuroplasticity, and the rate of apoptosis in the hippocampus. Therefore, exercise might be an important non-pharmacological intervention for the prevention and treatment of the pathobiology of PTSD.

Not recognized enough: The effects and associations of trauma and intellectual disability in severely mentally ill outpatients

Background:

Little is known about the association between trauma and intellectual disability in SMI patients.

Aim:

To establish the prevalence of trauma and its association with intellectual functioning in SMI outpatients.

Methods:

A cross-sectional study was conducted in two mental health trusts in the Netherlands. We used the Trauma Screening Questionnaire (TSQ) to screen for trauma and PTSD, and the Screener for Intelligence and Learning disabilities (SCIL) for suspected MID/BIF. Chi-square and t-tests were used to test differences in outcome over patient characteristics. Post-hoc analysis was used to investigate gender differences between patients with and without MID/BIF on trauma and sexual trauma.

Results:

Any trauma was found in 86% of 570 patients and 42% were suspected for PTSD. The SCIL suggested that 40% had Borderline Intellectual Functioning (BIF), half of whom were suspected of having Mild Intellectual Disability (MID). These patients had more traumatic experiences (1.89 in BIF, 1.75 in MID, against 1.41 in SCIL-negative patients). Female MID/BIF patients (61%) had experienced significantly more sexual abuse than male MID/BIF patients (23%).

Conclusions:

Significantly more SMI outpatients who screened positive for MID/BIF reported having experienced traumatic events than those who screened negative. Rates of all trauma categories were significantly higher in the screen-positive group, who were also more likely to have PTSD. Sexual abuse occurred more in all females but the SCIL positive women are even more often victim. Clinical practice has to pay more attention to all of these issues, especially when they occur together in a single patient.

Eye movement desensitization and reprocessing for adults with intellectual disabilities: Process issues from an acceptability study

BACKGROUND

Eye movement desensitization and reprocessing (EMDR) is recommended for post-traumatic stress disorder and emerging evidence indicates that it is effective for people with intellectual disabilities. However, acceptability from the perspectives of clients with intellectual disabilities, their therapists and other key people has not been formally evaluated. This study investigates process issues in the implementation of EMDR from perspectives of multiple stakeholders.

METHOD

Semi-structured interviews were conducted with two adults with intellectual disabilities and three clinical psychologists who had participated in EMDR as well as a key supporter (N = 6) to provide information relating to three cases. The interviews were analysed thematically either directly from the audio recording or from transcripts.

RESULTS

Five themes were identified: EMDR feels very different; EMDR is a technical process; the need to work with the present; talking is important; cautious optimism.

CONCLUSIONS

Whilst a range of client- and therapist-related factors served as barriers to using EMDR in this small-scale study, such as preferences in working with the present and inexperienced therapists, there was cautious optimism that EMDR may be useful for "the right person at the right time.".

A systematic review of cognitive behavioural therapy for anxiety in adults with intellectual disabilities

BACKGROUND

Anxiety disorders have high prevalence in people with intellectual disabilities. In populations without intellectual disabilities, cognitive behavioural therapy is a first line psychological therapy for these presentations. There is no existing review of the range of methods and outcomes from intervention studies in this area.

METHOD

A systematic review was carried out following guidance in the Cochrane handbook for systematic reviews of interventions.

RESULTS

Nineteen studies were identified. The majority of reports were descriptive case studies; the most frequently described presentations were non-specific anxiety disorders and post-traumatic stress disorder; the most frequently described cognitive techniques were psycho-education and interventions directly aimed at thoughts and beliefs and most studies reported positive outcomes, although the better controlled studies tended to report less comprehensive impacts.

CONCLUSIONS

A range of presentations have been described although the area is still at a primarily descriptive stage. We discuss intervention structures and approaches that require further research.

Multiple traumatisation and subsequent psychopathology in people with intellectual disabilities and DSM-5 PTSD: a preliminary study

BACKGROUND

Individuals with intellectual disability (ID) are at greater risk of exposure to traumatic life events compared with the non-ID population. Yet no study to date has examined the role of multiple traumatisation and subsequent psychopathology in people with ID. The aim of this study was to explore the association between multiple traumatisation and subsequent mental health.

METHODS

A preliminary cross-sectional study involving 33 participants with DSM-5 post-traumatic stress disorder completed self-report questionnaires on exposure to traumatic life events and post-traumatic stress disorder symptoms, anxiety, depression and general distress.

RESULTS

A proportion of 42.4% of the sample reported multiple traumatisation, including exposure to life events in both childhood and adulthood. Those who reported exposure to life events in childhood and adulthood reported significantly higher risk of harm, depression and general psychological distress compared with those who reported exposure to life events only in adulthood.

CONCLUSIONS

Preliminary results indicate that more severe psychopathology is associated with multiple traumatisation in childhood and adulthood compared with trauma experienced solely in adulthood.

Pilot study: undetected post-traumatic stress disorder symptoms among intellectually disabled

Background: Individuals with intellectual disability respond differently to traumatic events, compared to the general population, which makes post-traumatic stress disorder (PTSD) symptoms difficult to recognize. The current study aims to examine the presence of undetected PTSD among individuals with intellectual disability and a known history of trauma exposure. Method: Nine individuals, who have not previously been diagnosed with PTSD, were evaluated for PTSD symptoms through case reports, which include descriptions of medical history, symptoms and behavior described in the former diagnostic reports, potential traumatic experiences, current symptoms and behavior in accordance to the Lancaster and North Gate Trauma Scale, and PTSD criteria from DM-ID. Results: Four out of the nine participants met the DM-ID criteria for PTSD. Conclusions: The current findings highlight the importance of including cognitive impairment and developmental level in the screening, referral and treatment process of PTSD.

Disconnected lives: Women with intellectual disabilities in conflict with the law

BACKGROUND

Women with intellectual/developmental disabilities in conflict with the law experience childhood trauma, substance abuse and intimate partner violence but continue to have difficulty accessing appropriate therapeutic services, both within correctional settings and upon discharge. The aim of this study is to explore women's service needs and to critically assess whether the available services are meeting their identified needs.

METHOD

Semi-structured interviews were conducted with 16 women with intellectual/developmental disabilities who were in the Special Needs Unit of a women's correctional centre from December 2014 to March 2015.

RESULTS

Women with intellectual/developmental disabilities struggle to manage the impact of intergenerational trauma, exacerbated by issues of substance abuse and addiction, poor coping skills and minimal education, all of which impact their sense of well-being.

CONCLUSIONS

This study highlights the need for increasing trauma treatment for women with intellectual/developmental disabilities, and emphasizes the need for accessible intervention to facilitate coping, trauma processing and community integration.

Addressing the Needs of Children With Disabilities Experiencing Disaster or Terrorism

PURPOSE OF REVIEW

This paper reviews the empirical literature on psychosocial factors relating to children with disabilities in the context of disaster or terrorism.

RECENT FINDINGS

Research indicates adults with disabilities experience increased exposure to hazards due to existing social disparities and barriers associated with disability status. However, studies on the psychological effects of disaster/terrorism on children with pre-existing disabilities are exceedingly few and empirical evidence of the effectiveness of trauma-focused therapies for this population is limited. Secondary adversities, including social stigma and health concerns, also compromise the recovery of these children post-disaster/terrorism. Schools and teachers appear to be particularly important in the recovery of children with disabilities from disaster. Disasters, terrorism, and war all contribute to increased incidence of disability, as well as disproportionately affect children with pre-existing disabilities. Disaster preparedness interventions and societal changes are needed to decrease the disproportionate environmental and social vulnerability of children with disabilities to disaster and terrorism.

Traumatic Childhood Events and Autism Spectrum Disorder

Traumatic childhood events are associated with a wide range of negative physical, psychological and adaptive outcomes over the life course and are one of the few identifiable causes of psychiatric illness. Children with autism spectrum disorder (ASD) may be at increased risk for both encountering traumatic events and developing traumatic sequelae; however, this topic has been understudied. This review considers the rationale for examining traumatic events and related symptomology in individuals with ASD and summarizes the limited research on this topic. A conceptual framework for understanding the interplay of ASD, trauma and traumatic sequelae is proposed and recommendations for future research presented.

Mental Health Nursing of Adults With Intellectual Disabilities and Mental Illness: A Review of Empirical Studies 1994-2013

Mental health nursing for adults with intellectual disabilities and mental illness is underresearched. The aim of this review is to summarize empirical mental health nursing studies including adults with intellectual disabilities and additional mental illness. Out of 137 hits, 16 articles were reviewed in full text. Thirteen of the articles presented modified nursing interventions. Three articles discussed training and education. The main finding is that mental health nursing interventions in patients with intellectual disabilities and additional mental illness are in line with mental health nursing for the general population. There are still not many publications on empirical studies concerning mental health nursing for adults with intellectual disabilities. Clinical implications are primarily related to the need for facilitated nurse-patient communication adjusted to the patients' cognitive levels. Insights drawn from this review illuminate the importance of mental health nursing interventions adjusting to the particular patients' symptoms, instead of targeting behavior change. The findings underpin factors found to have a positive impact on patients with mental illness in the general population as relevant topics for future research.

Assessing posttraumatic stress disorder in children with mild to borderline intellectual disabilities

BACKGROUND

Evidence suggests that children with mild to borderline intellectual disabilities (MBID; IQ 50-85) have an elevated risk for both being exposed to potentially traumatic events and developing a posttraumatic stress disorder (PTSD). In this target group, PTSD often remains undiscovered due to a lack of diagnostic instruments. Valid instruments for the assessment of PTSD in children with MBID are therefore needed.

OBJECTIVE

The aim of the current study was to validate the adapted PTSD section of the Anxiety Disorders Interview Schedule for Children (ADIS-C) for the assessment of PTSD in children with MBID according to DSM-IV-TR and DSM-5 criteria.

METHOD

Eighty children (aged 6-18 years) with MBID who were referred to an outpatient psychiatric service and their primary caregivers were interviewed using the adapted ADIS-C.

RESULTS

The adapted ADIS-C PTSD section has excellent interrater reliability and good convergent validity. PTSD symptoms described spontaneously by children with MBID and their caregivers closely matched those included in the DSM-IV-TR and DSM-5. Many of the children who met Criterion A did not meet PTSD symptom criteria. Conversely, children meeting the full PTSD criteria were more likely than other children with MBID to have been exposed to at least one traumatic event meeting Criterion A and to a higher total number of potentially traumatic events.

CONCLUSIONS

The results support the reliability and validity of the adapted ADIS-C PTSD section for assessing PTSD in children with MBID. The use of this clinical interview helps to improve detection of PTSD and subsequent access to trauma-focused interventions for this at risk target group.

Consumer Information and Treatment Resources for Posttraumatic Stress Disorder: Within Reach but Not Grasp

In the context of multiple treatment options for posttraumatic stress disorder (PTSD) and a large, growing need for consumer information regarding accessible and effective treatments, this article identifies and reviews available information and treatment resources. Multiple search strategies identified a suite of information sources, including meta-analyses and systematic reviews of PTSD treatments, the program evaluation and implementation literature, the economics literature, Internet sites, and other resources for veteran and civilian consumers. Resources were evaluated with regard to their target audiences, depth and breadth of treatment options covered, nature of the information provided, and accessibility to consumers. A large body of research covers the various treatments and sets of treatment guidelines for PTSD. Despite the extensive scientific information targeted at providers and researchers, the quality, accessibility, and usability of the published research varies widely. The Veterans Health Administration provides the most extensive information on various treatment options and where to obtain treatment within that system. Publicly available websites provide information on multiple treatment options, but information to help nonveterans navigate treatment choices is limited. Published reports of PTSD program-evaluation and implementation studies are sparse. Information on PTSD treatment options available to consumers can be overwhelming and confusing, which places an unnecessary burden on an already vulnerable group of patients and their families. Exacerbating the situation is the shortage of program-evaluation and implementation research. The dearth of centralized and accessible information related to nonveteran PTSD patient groups needs to be addressed.
