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

COVID-19 pandemic among adults with intellectual disabilities: Implementing a social model of disability in crisis and trauma situations

A growing body of evidence has attested to the higher impact of COVID-19 on individuals with intellectual disabilities (IDs) than on members of the general population during the pandemic, mainly showing their higher vulnerability. However, we believe it is important to better understand how their situation interacts with the specific circumstances of the pandemic. In this article we discuss recent findings regarding individuals with IDs through the lens of two theories - the social disability model and the ecological model of trauma and recovery - and propose an integration, namely a social model of disability in crisis and trauma situations. Such a model allows for a wider perspective on understanding the way people living with disabilities (PLWDs) cope in these situations, integrating the individual aspects of coping with the social and environmental ones.

Clinicians' experiences of learning to use eye movement desensitisation and reprocessing therapy with people with intellectual disabilities: A qualitative study

BACKGROUND

Eye Movement Desensitisation and Reprocessing therapy (EMDR) is a NICE recommended treatment for post-traumatic stress disorder within the general population. Ongoing research is now investigating the use of EMDR for individuals with intellectual disability. Alongside quantitative research efforts, it is beneficial to explore the qualitative experience of clinicians adopting EMDR in their practice. The current study interviewed newly trained EMDR therapists working in intellectual disability services.

METHOD

Participants (six Clinical Psychologists from an NHS learning disability service) had recently undertaken EMDR training as part of a wider randomised control trial (Trauma-AID). Interviews were qualitatively analysed using thematic analysis.

RESULTS

Three themes emerged; learning EMDR, conducting EMDR and external factors, with respect to clinicians' experiences.

CONCLUSIONS

Further research is needed to provide guidance and reassurance for clinicians currently using or hoping to use this therapy with people with intellectual disabilities.

A call for trauma-informed dental care for individuals with intellectual disabilities

People with intellectual disabilities are at increased risk of dental anxiety and poor oral health. In addition, people with intellectual disabilities are at increased risk of potentially traumatic experiences, such as violence and sexual abuse, and appear to be more vulnerable to developing trauma-related disorders following such experiences. While psychological trauma is associated with poor oral health and dental anxiety in the general population, the potential link between dental anxiety, poor oral health and psychological trauma is yet to be explored in people with intellectual disabilities. In this conceptual paper, we provide an overview of recent findings concerning the relationships between oral health and intellectual disabilities, psychological trauma and intellectual disabilities, as well as between psychological trauma and oral health, and discuss the relevance of these findings related to dental care for people with intellectual disabilities. We conclude that psychological trauma is likely to contribute to dental anxiety and poor oral health also in people with intellectual disabilities. Implications include an urgent need for research exploring how trauma affects oral health and experiences of dental care for people with intellectual disabilities, as well as the importance of individualized and trauma-informed dental care for these individuals.

Trauma treatment using Narrative Exposure Therapy adapted to persons with intellectual disabilities or severe chronic mental disorders - a randomised controlled pilot study with an embedded observational study

BACKGROUND

Despite an increased likelihood of experiencing traumatic events and increased vulnerability, there are only few publications on trauma therapy for persons with intellectual disabilities (IDs). This pilot study for the first time investigates the feasibility and effectiveness of Narrative Exposure Therapy (NET) within this target group modified by Plain Language.

METHODS

A group of n = 10 participants with ID dual diagnoses and another group of n = 5 participants with severe and chronic mental disorders were separately stratified and randomised, then forming together an intervention group (n = 7) and a waiting list control group (n = 8). All participants were treated with NET attuned to their communication abilities by using Plain Language. Primary outcome was the post-traumatic stress measured with the Post-Traumatic Symptom Scale-10 before and after the intervention. In addition, the Adverse Childhood Experience Index was used for diagnostic purposes. Data were analysed using t-test for repeated measures and analysis of covariance.

RESULTS

Narrative Exposure Therapy and the randomised controlled trial study proved to be successfully conductible with participants with IDs in a congregated residential service. Although the corresponding effect size was high (partial eta square = 0.188), the between-group difference was not significant (P = 0.12). Analysis of the observational study resulted in a highly significant improvement for participants with IDs (P < 0.001; Hedges' g = 2.36) and in a significant improvement in participants with severe and chronic mental disorders (P < 0.013; Hedges' g = 1.52). Additionally, the participants with IDs show a significantly better reduction of symptom burden (P = 0.03; partial eta square = 0.327).

CONCLUSIONS

The results provide a first evidence for a possible and successful implementation of NET modified in Plain Language for persons with IDs and complex mental health support needs. Completeness in responding to the items of Post-Traumatic Symptom Scale-10 and Adverse Childhood Experience Index indicates the suitability of these instruments for both groups of participants. Although the group difference in the randomised controlled trial failed to achieve statistical significance mainly due to the small sample size, the results of the embedded observational study are promising for the conduct of further studies with the modified NET.

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.

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.

Self-Report Stress Measures to Assess Stress in Adults With Mild Intellectual Disabilities-A Scoping Review

Stress has a major negative impact on the development of psychopathology and contributes to the onset of adverse physical conditions. Timely recognition and monitoring of stress-related problems are therefore important, especially in client populations that are more vulnerable to stress, such as people with mild intellectual disabilities (MID). Recent research on the use of physiological measures to assess stress levels emphasize that, in addition to these measures, self-report instruments are necessary to gain insight into the individual perception and impact of stress on daily life. However, there is no current overview of self-report stress measures that focus on the experience of stress in the present moment or in daily life. To provide an overview of the existing self-report stress measures for clinicians and researchers, a scoping review was conducted. In addition, to advise clinical professionals on the use of self-report measures of stress for people with MID, the results of an expert consultation were used to refine the preliminary findings. A systematic scoping literature search resulted in a total of 13 self-reported stress measures that met the final inclusion criteria, of which three were developed specifically for assessing stress in adults with MID (GAS-ID, LI, and SAS-ID). For each included self-report stress measure, the psychometric quality, assessment procedure, and suitability for adults with MID were reported. These were supplemented by the findings from the expert consultation. Implications for clinical practice on the use of self-report stress measures, particularly for people with MID, are discussed. Recommendations for future research and development are given.

Trauma, intellectual and/or developmental disability, and multiple, complex needs: A scoping review of the literature

BACKGROUND

Trauma is a significant underlying factor in the multimorbidity of people with Intellectual and/or Development Disabilities (IDD). This relationship is further complicated by a growing recognition of a subset of multiply stigmatized individuals with an IDD and complex, intersecting health and social needs.

AIM

The aim of this review was to examine what is known about trauma and people with an IDD and complex needs, as defined by Community Living British Columbia's (CLBC) Multiple, Complex Needs (MCN) framework, through a broad review of relevant literature.

METHOD AND PROCEDURES

We conducted a scoping review of the peer-reviewed (9 disability journals; 7 academic databases) and grey (2 grey literature databases) on IDD and trauma through an inclusive approach that used search criteria drawn from the defining features of CLBC's MCN Framework.

OUTCOMES AND RESULTS

Apart from there being a limited amount of research on trauma and IDD, two key findings emerged. Through differing approaches that get at issues of trauma in different ways (i.e., through adverse life events or experiences of abuse), the first finding is that the research related to trauma and IDD is not cleanly linked together. The second is the focus on treatment services or interventions and not on what's happening at the organizational or system level.

CONCLUSION AND IMPLICATIONS

There is limited research on trauma and IDD making it even more important to unify the evidence that exists. However, the literature is not integrated across different theoretical and disciplinary perspectives. In addition, the focus of trauma-related research that is occurring is interventions at the individual versus system level. Also needed are studies that explore trauma-informed practice from an organizational or top-down perspective.

Prevalence of and relationship between adverse childhood experiences and family context risk factors among children with intellectual disabilities and borderline intellectual functioning

BACKGROUND

Adverse Childhood Experiences (ACEs) are an overlooked risk factor for behavioural, mental and physical health disparities in children with intellectual disabilities (ID) and borderline intellectual functioning (BIF).

AIMS

To gain insight into the presence of the 10 original Wave II ACEs and family context risk variables in a convenience sample of children with ID and BIF in Dutch residential care.

METHODS AND PROCEDURES

134 case-files of children with ID (n = 82) and BIF (n = 52) were analysed quantitatively.

OUTCOMES AND RESULTS

81.7 % of the children with ID experienced at least 1 ACE, as did 92.3 % of the children with BIF. The average number of ACEs in children with ID was 2.02 (range 0-8) and in children with BIF 2.88 (range 0-7). About 20 % of the children with moderate and mild ID experienced 4 ACEs or more. Many of their families faced multiple and complex problems (ID: 69.5 %; BIF 86.5 %). Multiple regression analysis indicated an association between family context risk variables and the number of ACEs in children.

CONCLUSIONS AND IMPLICATIONS

The prevalence of ACEs in children with ID and BIF appears to be considerably high. ACEs awareness in clinical practice is vital to help mitigate negative outcomes.

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.

From the DSP Perspective: Exploring the Use of Practices That Align With Trauma-Informed Care in Organizations Serving People With Intellectual and Developmental Disabilities

Trauma-informed care (TIC) is a systemwide approach that emphasizes organizational practices based upon principles of safety, choice, collaboration, empowerment, and trustworthiness. It is intended to influence an entire organization, with implications for clients and the workforce. The present study explored the extent to which IDD organizations utilize practices that align with TIC with their DSP workforce. Through an online survey, 380 DSPs (84% women; 82% white) responded to a trauma-informed organizational culture measure. Results demonstrated variability across items and significant differences between TIC principles with safety most strongly scored, and collaboration least strongly scored. Perception of organizational practices differed by ethnicity, with non-white DSPs having more favorable responses. Current practices with DSPs align with TIC, however, increased attention through explicit trauma-informed initiatives is warranted.

"If we do not look for it, we do not see it": Clinicians' experiences and understanding of identifying post-traumatic stress disorder in adults with autism and intellectual disability

BACKGROUND

Individuals with autism spectrum disorder (ASD) and intellectual disability (ID) are at increased risk of potentially traumatic events and may be at increased risk of post-traumatic stress disorder (PTSD). However, knowledge regarding identification of PTSD in this population is limited. The aim of this study was to investigate clinical experience regarding PTSD and trauma assessment in individuals with co-occurring ASD and ID.

METHOD

Interpretative phenomenological analysis was used to explore experiences of identifying PTSD in this population among 18 mental health clinicians working with ASD and ID.

RESULTS

Informants viewed PTSD in individuals with ASD and ID as equivalent to PTSD in the general population, but with causes and expressions potentially differing. Several factors were described to contribute to challenges in identification.

CONCLUSIONS

Trauma may have severe impact in individuals with ASD and ID. Multidimensional, individualized assessment strategies seem necessary to recognize PTSD or trauma-related symptoms in this population.

“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.

Adverse Childhood Experiences in Children with Intellectual Disabilities: An Exploratory Case-File Study in Dutch Residential Care

Adverse Childhood Experiences (ACEs) are negative childhood events occurring in a child’s family or social environment, that may cause harm or distress. Children with intellectual disabilities (ID) and their families are underrepresented in international ACEs research, while current insights can also contribute to the improvement of their health and well-being. Deficiencies in intellectual and adaptive functioning and living circumstances can increase their vulnerability to adversities. In the present exploratory study 69 case-files of children referred to a Dutch national center for residential youth care for children with ID were analyzed to assess the prevalence and associations of ACEs. It was found that almost half (49.3%) of the children experienced 2 ACEs from the original ACEs framework or more (M (mean) = 2.1; SD (standard deviation) = 1.8) and that the number of ACEs in children was related to the presence of ACEs in parents. Both child and parental ACEs were also related to attachment- and trauma- and stressor-related disorders. Finally, living circumstances and multiple ACEs from the expanded ACEs framework, especially related to parental characteristics, were found to be related to ACEs in children with ID. This implicates the importance of a transgenerational approach when further investigating the impact of ACEs on mental and physical health in children with ID (intellectual disabilities).
