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?

Stressful life events, post-traumatic stress disorder symptoms and mental health in individuals with intellectual disabilities: a scoping review

BACKGROUND

Stressful life events are events that do not fulfil the A criterion of PTSD in the DSM-5(TR) but are perceived as negative by the person. There is an ongoing debate about the usefulness of the A criterion as a gate criterion for PTSD, and especially regarding which events qualify as traumatic or stressful life events. This debate is particularly important for individuals with intellectual disabilities (ID) or borderline intellectual functioning (BIF), as they seem to be more likely to experience traumatic and stressful life events than their peers without ID-BIF and appear to be more susceptible to the disruptive effects of these events. As a result, people with ID-BIF are more likely to develop mental health and behavioural problems. There is insufficient knowledge about how the relationship between stressful life events and PTSD symptoms should be interpreted, how traumatic and stressful life events are defined and distinguished in people with ID, and whether the A criterion should be broadened for individuals with ID-BIF. The aim of this scoping review was to understand stressful life events and their relationship with PTSD symptoms, other mental health and/or behavioural problems in individuals with ID-BIF.

METHODS

The scoping review was conducted in accordance with the JBI methodology for scoping reviews and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR).

RESULTS

Thirty-eight studies were included. Five studies focused on stressful life events and PTSD symptoms. The other studies examined associations between stressful life events and other mental health and/or behavioural problems. Most of the studies did not clearly differentiate between stressful and traumatic events according to the A criterion of PTSD in the DSM-IV (TR) or DSM-5(TR). Of the six studies in which stressful life events were specified and could be distinguished from traumatic events, one found a positive association between PTSD symptoms and stressful life events and five showed weak to strong positive associations with other mental health and/or behavioural problems.

CONCLUSIONS

PTSD symptoms following stressful life events in individuals with ID-BIF are underrepresented in the literature. The lack of a clear definition of stressful life events leads to a gap in the knowledge on whether and how stressful life events may lead to PTSD symptoms, other mental health and/or behavioural problems in individuals with ID-BIF. Therefore, no general conclusions or recommendations can be made regarding the appropriateness of the PTSD A criterion for individuals with ID-BIF. Further research is needed to establish the role of stressful life events in relation to PTSD symptoms and to inform the assessment and effective treatment in people with ID-BIF, as expert clinical experience studies suggest that broadening the PTSD A criterion should be considered for people with ID-BIF.

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.

A review on post-traumatic stress disorder (PTSD): "Symptoms, Therapies and Recent Case Studies"

Post-traumatic stress disorder (PTSD), previously known as battle fatigue syndrome or shell shock, is a severe mental disturbance condition that is normally triggered by the experience of some frightening/scary events or trauma where a person undergoes some serious physical or mental harm or threatened. PTSD is a long-life effect of the continuous occurrence of traumatic conditions which, leading the production of feelings of helplessness, intense fear, and horror in the person. There are various examples of events that can cause PTSD, such as physical, mental, or sexual assault at home or working place by others, unexpected death of a loved one, an accidental event, war, or some kind of natural disaster. Treatment of PTSD includes the removal or reduction of these emotional feelings or symptoms with the aim to improve the daily life functioning of a person. Problems which are needed to be considered in case of PTSD like ongoing trauma, abusive or bad relationships. Various drugs which are used for the treatment of PTSD include selective serotonin reuptake inhibitors (SSRIs) (citalopram, fluvoxamine, fluoxetine, etc.); tricyclic antidepressants (amitriptyline and isocarboxazid); mood stabilizers (Divalproex and lamotrigine); atypical antipsychotics (aripiprazole and quetiapine), etc. In this review, we have covered the different risk factors, case studies related to various treatment options with different age group peoples in PTSD and their effects on them. We have also covered the symptoms and associated disorders which can play a key role in the development of PTSD.

Potentially traumatic experiences and behavioural symptoms in adults with autism and intellectual disability referred for psychiatric assessment

BACKGROUND

Individuals with autism spectrum disorder (ASD) and intellectual disability (ID) more frequently experience potentially traumatic events (PTEs), and may be more vulnerable to trauma-related symptoms. However, it is unclear how such symptoms are captured on tools used for behavioural and psychiatric assessment in this population.

AIMS

To explore whether and how PTEs are associated with symptom reports in adults with ASD and ID.

METHODS AND PROCEDURES

Associations and group differences for death of a close relative and serious disease/injury in a close relative/caregiver/friend were explored in a clinical sample of 171 adults with ASD and ID referred for psychiatric assessment. Symptoms were measured using Aberrant Behavior Checklist (ABC) and Psychopathology in Autism Checklist (PAC).

OUTCOMES AND RESULTS

Disease/injury was associated with higher scores on ABC irritability, ABC hyperactivity and self-injurious behaviour. Death was associated with lower scores on ABC lethargy and ABC stereotypic behaviour. Some associations reached significance only when controlling for ASD, ID, or verbal language skills, but the identified associations were not robust. No associations were found for PAC.

CONCLUSIONS AND IMPLICATIONS

There is a risk of under-appreciating the impact of PTEs in this population unless ASD, ID and verbal language skills are taken into account.

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.

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.

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.
