Exposure to life events as a risk factor for psychological problems in adults with intellectual disabilities: a longitudinal design

The prospective associations between autonomy support, basic psychological needs, motivation and well-being among people with a mild to borderline intellectual disability: a two-wave study

BACKGROUND

This study, grounded in self-determination theory, examined how satisfaction of the needs for autonomy, relatedness and competence in people with mild to borderline intellectual disability (MBID) changed over a 4.5-year period. Additionally, it explored the association between life events across various domains (i.e. health, support and living situation, crime, relationships and freedom and finance) and these changes and explored the prospective associations between these needs, perceptions of support from direct support staff and the well-being and ill-being of people with MBID.

METHODS

Based on a sample of 117 adults with MBID, multiple regression analyses were conducted to determine correlations between constructs at both time points and the impact of autonomy support on need satisfaction and motivation, taking into account life events.

RESULTS

The analyses showed that, at both time points, most constructs were statistically significantly correlated and remained so despite a time lag of 4.5 years. Autonomy support emerged as a significant positive predictor, of medium size, for satisfying autonomy and relatedness needs. Its association with competence need satisfaction was not statistically significant after Bonferroni correction. For type of motivation, autonomy support statistically predicted increased autonomous motivation, irrespective of life events.

CONCLUSIONS

Findings underline the potential of autonomy supportive direct support in the lives of individuals with MBID. Some unexpected null findings underscore the need for further study into the interplay between autonomy support, life events and the well-being of people with MBID.

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.

Assessing Alignment Between Intellectual and Developmental Disability Service Providers and Trauma-Informed Care: An Exploratory Study

People with intellectual and developmental disabilities (IDD) are disproportionately impacted by potentially traumatic experiences; however, organizations serving this population have lagged in their integration of trauma-informed care (TIC). Trauma-informed care is a systemwide response to the pervasiveness of trauma that frequently requires an organizational shift rooted in staff training. Using an online statewide survey, the present study examined beliefs and training among IDD service providers. Responses from 288 service providers suggested some alignment among beliefs and staff training content with TIC principles. Although the findings indicate a foundation for TIC, intentional efforts are needed for IDD agencies to fully embrace TIC.

The relationship between adverse interpersonal experiences and self-esteem in people with intellectual disabilities: The role of shame, self-compassion and social support

BACKGROUND

People with intellectual disabilities are reported to have low self-esteem and to experience high rates of adverse interpersonal experiences (AIEs). This study aimed to investigate whether shame and self-compassion mediate the relationship between AIEs and self-esteem for people with intellectual disabilities and whether perceived social support moderates this relationship.

METHOD

This study employed a cross-sectional design, involving between-group comparisons. Forty-seven people with intellectual disabilities and 50 people without intellectual disabilities completed self-report questionnaires measuring shame, self-compassion, self-esteem, early AIEs and social support.

RESULTS

Shame and self-compassion were found to mediate the relationship between AIEs and self-esteem for people with intellectual disabilities. There was no evidence for a moderating effect of social support and no difference between groups in shame or self-compassion.

CONCLUSIONS

The findings suggest shame and self-compassion are important concepts for people with intellectual disabilities. Clinical and research implications are discussed.

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.

Psychiatric symptoms, challenging behaviour and utilization of psychiatric services among adults with intellectual disabilities in Turkey

BACKGROUND

The aim of this study was to investigate the prevalence of and the factors associated with psychiatric symptoms (PS) and challenging behaviour (CB) in adults with intellectual disabilities, and the utilization of psychiatric services in Turkey.

METHOD

Psychiatric Assessment Schedule for Adults with Developmental Disorders Checklist-Revised was used for PS and a structured form for other variables in 771 participants.

RESULTS

Of the participants, 50.1% had PS and 36.4% presented with CB. Multivariate analysis revealed that a higher level of needs, better verbal ability, residential living, incontinence and CB, and lifetime suicidal ideation/attempt were independently associated with PS. For CB, it emerged as male carer, PS, lifetime suicidal attempt/ideation, lower level of verbal ability and autism spectrum disorder. Barriers were experienced by 64.7% of participants within the previous year.

CONCLUSIONS

Psychiatric symptoms and CB seem to be problems for a significant proportion of adults with intellectual disabilities in Turkey, and there are certain barriers to psychiatric services.

Resilience in the face of adversity in adults with an intellectual disability: A literature review

Background

Persons with an intellectual disability are at a higher risk of experiencing adversities. The concept of resilience offers promising insights into facilitating personal growth after adversity. The current study aims at providing an overview of the current research on resilience and the way this can contribute to quality of life in people with intellectual disability.

Method

A literature review was conducted in the databases PsycINFO and Web of Science. To evaluate the quality of the studies, the Mixed Method Appraisal Tool (MMAT) was used.

Results

The themes, autonomy, self‐acceptance and physical health, were identified as internal sources of resilience. External sources of resilience can be found within the social network and daily activities.

Conclusion

The current overview shows promising results to address resilience in adults with intellectual disability. More research is needed to identify the full range of resiliency factors.

Associated Risk Factors for Depression and Anxiety in Adults With Intellectual and Developmental Disabilities: Five-Year Follow Up

A better understanding of the factors associated with depression and anxiety in people with intellectual and developmental disabilities (IDD) is needed to provide guidelines for service providers, clinicians, and researchers as well as to improve the diagnostic process. The current study used a longitudinal dataset to explore demographic, health, and psychosocial risk factors of anxiety and depression in adults with IDD. Women were more likely to have depression while older adults, people with autism, and people with hearing impairments, were more likely to have anxiety. Chronic health conditions were associated with both anxiety and depression, while changes in stressful life events were associated with an increased risk of anxiety. Clinical and research contributions are discussed.

The association of life events and mental ill health in older adults with intellectual disability: results of the wave 3 Intellectual Disability Supplement to The Irish Longitudinal Study on Ageing

BACKGROUND

Exposures to life events are associated with emotional, psychological and behavioural problems in those with intellectual disability (ID). Older adults with ID may experience different life events given differences in living circumstances, cognitive decline, greater dependency on others and less autonomy. This study examines the relationship of life events and mental ill health in an older ID population in Ireland.

METHODS

The study was part of 'The Intellectual Disability Supplement to The Irish Longitudinal Study on Ageing'. The frequency of life events was assessed using a 20-item checklist, and the level of stress experienced was assessed using a three-point Likert scale measuring the burden of the life event. The associations of life events with factors associated with mental ill health were measured using a variety of self-report and proxy completed questionnaires.

RESULTS

For the study population, 88.1% had been exposed to at least one life event in the preceding 12 months and 64.5% to two or more life events. Frequency and burden of life events were significantly higher in individuals living in institutional settings and in individuals with any current psychiatric condition, increased depressive and anxiety symptoms, challenging behaviour and reported poorer self-rated mental and physical health. More life events were significantly associated with new psychiatric diagnoses as well as initiation and increased dosage of mood stabilising, hypnotic and sedative medications.

CONCLUSIONS

Life events are significantly associated with mental ill health in the older ID population. Service providers must focus on limiting the exposure to these events and, in situations where they cannot be avoided, should support and manage individuals compassionately and effectively, prioritising their mental and physical well-being.

The prevalence of mental health problems in adults with intellectual disabilities in Japan, associated factors and mental health service use

BACKGROUND

People with intellectual disabilities are more likely than people in the general population to experience life events associated with an increased risk of mental health problems. However, there has been little research in Japan on the prevalence of mental health problems in adults with intellectual disability (ID) or on associated factors and access to relevant services.

METHODS

Informants completed the Japanese version of the Psychiatric Assessment Schedule for Adults with Developmental Disabilities Checklist, and questions on the use of mental health services, for 126 adults with ID living in Tokyo.

RESULTS

A total of 23.8% of adults with ID had scores above the Psychiatric Assessment Schedule for Adults with Developmental Disabilities Checklist threshold score. Mental health problems were associated with age, gender and life events and not associated with the level of ID or living environment. Approximately 60% of participants with mental health problems were treated by psychiatrists and 6% of them received psychotherapy.

CONCLUSION

In the present study, mental health problems occurred in adults with ID at similar frequencies as in previous studies. Adults with ID who experienced mental health problems tended to receive less psychological therapy than the general Japanese population experiencing such problems. This result may indicate poor provision of psychological services for people with intellectual disabilities in Japan.

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).

Prevalence and psychological sequelae of sexual abuse among individuals with an intellectual disability: A review of the recent literature

The impact of sexual abuse among those with an intellectual disability is an area in need of further research. The current article provides an in-depth narrative review of the sexual abuse literature relevant to individuals with an intellectual disability. The 29 articles included in this study focused on (a) the prevalence of sexual abuse, (b) the risk factors associated with this population, and (c) the psychological impact of abuse. The findings confirmed that children and adults with an intellectual disability are at a higher risk of sexual abuse than nondisabled peers. Research regarding risk factors is equivocal, with a range of possible factors indicated. Similarly, evidence suggests that there is no single diagnostic trajectory when dealing with the sequelae of sexual abuse among those with an intellectual disability. The article concludes by discussing recommendations for future research and development of policy around this area.

Prevalence and associated factors of problem behaviours among older adults with intellectual disabilities in Ireland

A growing number of adults with intellectual disabilities (ID) are reaching old age, however, little is known about epidemiology of problem behaviours (PBs) in this population. The aim was to identify the prevalence and associated factors of PBs among older adults with ID in Ireland. Data was generated from Wave 2 of the Intellectual Disability Supplement to the Irish Longitudinal Study on Ageing (IDS-TILDA), a nationally representative sample of adults with ID aged ≥40. Data on PBs was available for 683 (98.3%) of individuals. Over half (53%; n = 362) reported displaying any PB (verbal aggression, physical aggression, destruction, self-injury, or "other" PB). Multivariate analyses indicated PBs were independently associated with moderate or severe/profound ID, living in a community group home or residential centre, experiencing a greater number of life events in the last year, taking psychotropic medication, and reporting a doctor's diagnosis of a psychiatric problem. A considerable number of older adults with ID in Ireland display PBs, which may hinder their opportunities to engage in community based activities and form meaningful social connections. High rates of psychotropic medication and doctor's diagnosis of psychiatric conditions and their associations with PBs were highlighted. Future research should examine mechanisms underlying these linkages.

Sexuality issues and the voices of adults with intellectual disabilities: A systematic review of the literature

BACKGROUND

There is a growing and evolving research evidence base regarding sexuality issues and adults with intellectual disabilities. Individuals can face challenges, including the right to express their sexuality and to access necessary education and supports.

AIMS

This systematic review explores sexuality experiences, the views and opinions of adults with intellectual disabilities and highlights areas for future practice developments.

METHODS AND PROCEDURES

A comprehensive search of relevant databases from January 2006 to December 2016 was carried out. Included studies had to address specific criteria including: peer reviewed papers, the use of appropriate research methods, and focused exclusively on the individual views and opinions of people with an intellectual disability. The search of relevant databases yielded 230 hits. Following the application of explicit inclusion and exclusion criteria, 23 papers were deemed suitable for the review.

OUTCOMES AND RESULTS

The data were analysed and key themes were identified that included: autonomy v's risk of harm, knowledge and sexuality, relationships and intimacy, self-determination and taking control, and encouragement and supports.

CONCLUSIONS AND IMPLICATIONS

Adults with intellectual disabilities need education and support to express their sexuality and to meet individual needs.

Identifying classes of persons with mild intellectual disability or borderline intellectual functioning: a latent class analysis

BACKGROUND

Persons with mild intellectual disability or borderline intellectual functioning are often studied as a single group with similar characteristics. However, there are indications that differences exist within this population. Therefore, the aim of this study was to identify classes of persons with mild intellectual disability or borderline intellectual functioning and to examine whether these classes are related to individual and/or environmental characteristics.

METHODS

Latent class analysis was performed using file data of 250 eligible participants with a mean age of 26.1 (SD 13.8, range 3-70) years.

RESULTS

Five distinct classes of persons with mild intellectual disability or borderline intellectual functioning were found. These classes significantly differed in individual and environmental characteristics. For example, persons with a mild intellectual disability experienced fewer problems than those with borderline intellectual disability.

CONCLUSIONS

The identification of five classes implies that a differentiated approach is required towards persons with mild intellectual disability or borderline intellectual functioning.

A prospective study of the relationship between adverse life events and trauma in adults with mild to moderate intellectual disabilities

BACKGROUND

Research has demonstrated a relationship between the experience of life events and psychopathology in people with intellectual disabilities (ID), however few studies have established causal links and to date no prospective studies have utilised a measure of trauma that has been developed specifically for this population group.

METHOD

This 6-month prospective study examined longitudinal relationships between adverse life events and trauma in 99 adults with mild to moderate ID.

RESULTS

Life events during the previous 6 months were significantly predictive of levels of trauma as measured by the self-report Lancaster and Northgate trauma scales (LANTS), and the informant LANTS behavioural changes, frequency and severity sub-scales. This prospective causal relationship was demonstrated while controlling for any prior life events or pre-existing trauma, though the relationship was not moderated by social support.

CONCLUSIONS

Evidence of a causal relationship between adverse life events and trauma symptoms is important for treatment planning and funding allocation.

Bereavement and behavioral changes as risk factors for cognitive decline in adults with Down syndrome

BACKGROUND

Cognitive decline and Alzheimer's disease often affect older adults with Down syndrome (DS) much earlier than those in the general population. There is also growing evidence of the effects of negative life events on the mental health and behavior of individuals with intellectual disability. However, to our knowledge, this is the first study investigating objective cognitive decline following bereavement in aging individuals with DS.

OBJECTIVE

The objective of this study was to determine whether cognitive decline correlates with bereavement following the recent loss of a caregiver or with behavioral changes in a sample of adult individuals with DS who do not meet the criteria for dementia or depression, using the longitudinal assessment of the Cambridge Cognitive Examination (CAMCOG), together with the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE).

METHODS

We evaluated 18 subjects at baseline and over a follow-up period of 14-22 months, attempting to determine whether cognitive decline correlates with bereavement following the recent loss of the main caregiver or with behavioral changes (as assessed with the Neuropsychiatric Inventory).

RESULTS

The mean rate of change in CAMCOG was -1.83 (standard deviation 4.51). Behavioral changes had a significant direct influence on cognitive decline. When bereavement was accompanied by behavioral changes, the probability of cognitive decline was 87% (odds ratio 3.82).

CONCLUSION

The occurrence of behavioral changes attributed to bereavement following the loss of the primary caregiver significantly increases the probability of cognitive decline in individuals with DS. Longitudinal comparison of the CAMCOG and use of the IQCODE appear to enrich the analysis of cognitive decline in individuals with DS. Further studies involving larger samples are needed in order to corroborate and expand upon our findings, which can have implications for the clinical management of older adults with DS.
