Prevalence of co-occurring psychiatric disorders in adults and adolescents with intellectual disability: A systematic review and meta-analysis

Prevalence of psychiatric conditions in people with intellectual disability: A record linkage study in New South Wales, Australia

OBJECTIVE

To compare the prevalence of psychiatric conditions in a population-based cohort of people with intellectual disability and matched comparators in New South Wales, Australia.

METHOD

The study cohort included 97,644 people with intellectual disability and 451,502 comparators aged ⩾ 5 between 1 July 2001 to 30 June 2018. We used linked records of hospital admissions, emergency department presentations, ambulatory mental health service contacts, and Medicare rebates to identify any, serious, and specific psychiatric conditions.

RESULTS

People with intellectual disability showed greatly elevated period prevalence of any psychiatric condition (76.0% vs 38.3%), serious mental illness (16.2% vs 5.1%), and all specific psychiatric conditions compared to comparators. Among people with intellectual disability and congenital/developmental conditions, people with Down syndrome showed reduced risk of most psychiatric conditions while people with attention-deficit hyperactivity disorder and people with learning disorders showed increased risk. Age-specific analysis showed earlier onset of dementia and heightened prevalence of self-injury/suicidality in adulthood among people with intellectual disability. Annualised prevalence trends showed increases in 2006-2007 for most psychiatric conditions and decreases in 2014-2015 to 2017-2018.

CONCLUSIONS

The higher prevalence of psychiatric conditions in people with intellectual disability indicates the importance of systemic responses to address the mental health needs of this population. Our findings highlight the importance of considering the psychiatric profiles of specific congenital/developmental conditions among people with intellectual disability, and the need to provide targeted services to high-risk groups such as those with co-occurring attention-deficit hyperactivity disorder.

The risk of intellectual disability in offspring of diabetic mothers: A systematic review and meta-analysis

Epidemiological evidence on association between maternal diabetes and intellectual disability (ID) in offspring is mixed. This systematic review and meta-analysis aimed to synthesise the existing evidence to determine the extent and nature of this association. We systematically searched Embase, Web of Science, Scopus, PubMed, PsycINFO, and CINAHL databases from inception to March 14, 2023. The methodological quality of the included studies was assessed using the Newcastle-Ottawa Scale. Effect estimates for each exposure-outcome association were synthesised using a random-effects model Sensitivity and subgroup analyses were performed to identify potential sources of heterogeneity. A total of ten studies, comprising 8,927,706 mother-child pairs, met the inclusion criteria. Our analyses revealed that children exposed to any form of maternal diabetes had higher odds of ID compared to unexposed counterparts. Specifically, we found a 61 % higher risk of ID in offspring of mothers with any pre-existing diabetes. However, no significant association was found between gestational diabetes mellitus (GDM) and ID risk in offspring. The present meta-analysis suggests that exposure to pre-existing type 1 diabetes (T1D) and type 2 diabetes (T2D), but not GDM, is associated with increased risks of ID in offspring. Further high-quality studies, adequately adjusted for potential confounders, are needed to confirm these findings.

[A qualitative item analysis of the Scale of Emotional Developmental Diagnostics - Short (SED-S)]

The Scale of Emotional Development - Diagnostic (SEED) is a standardized diagnostic instrument based on the emotional development approach. It contributes to the diagnostic assessment of challenging behaviors in individuals with intellectual developmental disabilities. The 200-item scale determines the emotional reference age from 0-12 years in 8 domains. An expert survey showed a very good to good observability of the described behaviors, the specificity for a certain developmental phase and the appropriateness of the phrasing for children and adults while the non-differentiability to adjacent developmental phases was rated with "hardly". Regarding the differentiability, the major need for revision was described in the domains Relating to Their Own Body, Dealing with Change - Object Permanence, Differentiating Emotions and Regulating Affect and in phases 4 (reference ages: 4-7 years) and 5 (reference age: 8-12 years).

Electroconvulsive therapy in autism spectrum disorders: an update to the literature

PURPOSE OF REVIEW

Over the last quarter century, the clinical evidence surrounding the use of electroconvulsive therapy (ECT) in individuals with autism spectrum disorder (ASD) has expanded. This review provides the most up-to-date findings on the usage of ECT in ASD and discusses these results within the historical context and direct patient care experience.

RECENT FINDINGS

ECT is typically implemented for psychotropic-refractory catatonic, affective, psychotic, and combined pathology for individuals across the lifespan. Although highly stigmatized, ECT is well tolerated, efficacious, and potentially lifesaving for select individuals. A case presentation of an individual with autism as well as a summary of legal restrictions hampering his ECT access is presented.

SUMMARY

ECT is increasingly used in individuals with ASD who present with a wide range of ECT-responsive psychopathology, as well as repetitive self-injury and late, autistic-like regression for which no cause is found. ECT is well tolerated and offers real hope for many ASD individuals with devastating, treatment-refractory conditions.

Predictors of the Friendship Quality in Adults With Mild Intellectual Disability

BACKGROUND

Friendship quality is crucial for psychological well-being, yet is often lower in persons with intellectual disabilities compared to their peers. This study explores the predictors of friendship quality among adults with mild intellectual disability, focusing on age, gender, living setting, psychiatric traits, and social cognition.

METHOD

The sample comprised 62 adults with mild intellectual disability (32 males, 30 females; ages 19-53), and 30 with significant psychiatric traits. Tools included the Friendship Quality Scale, Edinburgh Social Cognition Test, MINI PAS-ADD scale, and a demographic questionnaire.

RESULTS

Social cognition and age were the strongest predictors of friendship quality, with higher social cognition scores and younger age correlating with better quality. Gender, living setting, and psychiatric traits had less impact.

CONCLUSIONS

Social cognition and age are primary determinants of friendship quality in adults with mild intellectual disability, suggesting that interventions to enhance social cognition may benefit this population's social well-being.

Pregnancy and postnatal outcomes for women with intellectual disability and their infants: A systematic review

BACKGROUND

While the perinatal period is a vulnerable time for women and their infants, it is also a window to promote adjustment and support. Women with intellectual disability might be a uniquely vulnerable group owing to pre-existing health and care inequalities. The aim of this paper is to explore the pregnancy and postnatal outcomes of women with intellectual disability and the health and development of their infants.

METHODS

Three electronic databases (MEDLINE, PsycINFO, EMBASE) were searched for peer-reviewed papers that reported maternal pregnancy variables and infant outcomes within the first 12 months of life. Two reviewers screened 103 full text articles, of which nine met eligibility criteria. Data reporting maternal health, pregnancy complications, labour variables, and birth and neonatal outcomes were extracted, and findings were summarised narratively.

FINDINGS

Women with intellectual disability were at an overall higher risk of adverse obstetric and pregnancy outcomes, such as urinary tract infection, gestational hypertension, and postpartum haemorrhage. Similarly, infants of women with intellectual disability had higher rates of premature birth, perinatal mortality, and experienced longer hospital stays when compared to their counterparts born to women without intellectual disability.

CONCLUSIONS

The relative sparsity of literature in this field demonstrates the need for further focused study on the pregnancy and postnatal outcomes of women with intellectual disability and their infants. Nonetheless, findings indicate that maternity services need to be further developed to provide optimum care for women with intellectual disability and to support infant development.

[Electroconvulsive therapy in people with intellectual disability]

Electroconvulsive therapy (ECT) is a highly effective treatment option for severe mental illness. Although people with intellectual disability (ID) have similar prevalence rates of mental disorders in comparison to the general population their access to ECT remains challenging. A systematic literature review was carried out on treatment with ECT in patients with ID and a case report on a patient with ID who underwent ECT is presented, to highlight a typical clinical routine. A total of 100 articles with 208 different case reports were retrieved. In summary, the results underline the effectiveness of ECT in people with ID, with side effects comparable to those in the general population. The ECT is effective in the treatment of severe affective and psychotic disorders and particularly in people with catatonia. The use of ECT can improve the patient's mental health and quality of life and is often a life-saving treatment option. The prophylaxis of relapses should be included as early as possible in the planning process. Providing an easy access to ECT treatment for people with ID is corroborated by its effectiveness and is in line with the right to equal treatment in accordance with article 25 of the United Nations Convention on the Rights of Persons with Disabilities.

Healthy ageing for older adult people with intellectual disability: a scoping review

BACKGROUND

The increasing longevity of people with intellectual disability creates a need for a healthy-ageing perspective, translated into evidence-based interventions in this multi-morbidity group. Accordingly, the aim of this scoping review was to identify, summarise and analyse the empirical research on healthy ageing in older adults with intellectual disability.

METHODS

This review was based on the PRISMA 2020 guidelines for Scoping Reviews (PRISMA-ScR) and a PICO protocol (Patient/population, Intervention, Comparison/control, and Outcome). Empirical studies in English were included if they concerned older adults with intellectual disability with an average age of at least 45 and were based on a clearly expressed healthy-ageing perspective. An information specialist conducted a search in 11 databases with no geographical or temporal restrictions. Two independent researchers performed study selection, quality assessment and data extraction. Disagreements were resolved in consultation with a third researcher. A textual narrative synthesis was based on PICO domains and the seven research questions.

RESULTS

The 11 studies were all from developed countries and had different designs: qualitative, mixed-method and one systematic review. Only three studies highlighted the term "healthy ageing", most used synonymous terms. Eight studies focused on healthy ageing on the individual level, three on the organisational and societal level. The intervention studies in the systematic review were mainly nonrandomised, concerned interventions varying in intensity and duration, considered different research questions and employed different outcome measures.

CONCLUSIONS

The findings highlight a major knowledge gap concerning evidence-based interventions with a healthy-ageing perspective in the case of older adults with intellectual disability. There is an urgent need to initiate healthy-ageing studies in developing countries, where such people are even more vulnerable to stigma and discrimination than those in developed countries. Our findings confirm the need to scale up healthy-ageing interventions in line with the WHO's ambition to develop evidence-based approaches to optimise the functional capacity of all older people, including older adults with intellectual disability, by 2030.

REGISTRATION

The study is registered in the International Prospective Register of Systematic Reviews (PROSPERO), CRD42022337211 (13 June 2022).

Psychotic experiences and disorders in adolescents and young adults with borderline intellectual functioning and intellectual disabilities: evidence from a population-based birth cohort in the United Kingdom

BACKGROUND

Individuals with borderline intellectual functioning and intellectual disabilities (intellectual impairment) may be at increased risk of psychosis. However, studies have been limited by small and selected samples. Moreover, the role of early life trauma, a key risk factor for psychosis, in the associations is unknown.

METHODS

Using data from the Avon Longitudinal Study of Parents and Children (ALSPAC) birth cohort, we investigated the associations between intellectual impairment, psychotic disorders, and psychotic experiences, and assessed the mediating role of trauma in childhood. Individuals with intellectual impairment were identified using a multisource measure utilizing indicators from ALSPAC combined with health and administrative records. Psychotic disorder diagnoses were extracted through linkage to primary care records. Psychotic experiences were assessed at ages 18 and 24 using the semi-structured Psychosis-Like Symptoms interview (PLIKSi). Trauma between ages 5 and 11 was assessed with questionnaires and interviews administered to children and parents at multiple ages. Multiple imputation was performed to mitigate bias due to missing data.

RESULTS

The maximum sample after multiple imputation was 9,407. We found associations between intellectual impairment and psychotic disorders (OR = 4.57; 95%CI: 1.56-13.39). Evidence was weaker in the case of psychotic experiences (OR = 1.63; 95%CI: 0.93-2.84). There was some evidence suggesting a mediating role of trauma in the associations between intellectual impairment and psychotic experiences (OR = 1.09; 95%CI: 1.03-1.15). Complete records analyses yielded comparable estimates.

CONCLUSIONS

Intellectual impairment is associated with psychotic disorders and experiences in adulthood. Research into the contribution of trauma could shape intervention strategies for psychotic disorders in this population.

Prevalence of Psychotropic Medication Use and Psychotropic Polypharmacy in Autistic Adults With or Without Intellectual Disability

The aim of this study was to compare the rates of psychotropic medication use and psychotropic polypharmacy between autistic adults with and without intellectual disability (ID) and to examine factors associated with psychotropic medication use and psychotropic polypharmacy in autistic adults, stratified by the presence of ID. We conducted a retrospective medical chart review of outpatients with an autism diagnosis aged 18 years and older. The rates of psychotropic medication use and psychotropic polypharmacy were compared between autistic adults with and without ID. Subsequently, logistic regression analyses were performed to identify factors associated with psychotropic medication use and psychotropic polypharmacy in autistic adults with ID and those without ID, respectively. The rates of prevalence of psychotropic medication use and polypharmacy were significantly higher in participants with ID than those without ID (78.6% vs. 58.8% and 49.3% vs. 31.2%; p-values < 0.05). Age, gender, race, residence, presence of mood disorders, presence of schizophrenia, absence of anxiety disorder, number of psychiatric comorbidities, and presence of behaviors that challenge were significantly associated with these outcomes, depending on the presence/absence of ID. The need to optimize pharmacotherapy in autistic adults, stratifying by the presence of ID, is highlighted.

Mental Health Services for Adults With Intellectual Disabilities: A Qualitative Study of Patient Characteristics, Associated Factors and Consequent Needs for Adaptation in Assessment and Treatment

BACKGROUND

Individuals with intellectual disabilities are at increased risk of mental health disorders, but may struggle to access appropriate services. While assessment/treatment may need to be adapted, knowledge is limited about what such adaptations may entail.

METHOD

During a service development project, the participants (33 professionals, 13 family members) were asked to identify the characteristics/associated factors of individuals with intellectual disabilities and co-occurring mental health disorders. Using thematic analysis, 1103 participant responses were analyzed to identify the needs for adaptation in assessment/treatment.

RESULTS

Three core themes were identified: (1) A broader assessment: Gaining an accurate and comprehensive understanding of the individual's history, abilities and difficulties, (2) Adjusting/modifying existing treatment strategies, (3) Ensuring that the individual's day-to-day needs are met.

CONCLUSIONS

According to the participants, assessment/treatment of mental health disorder in this population requires more time and broader assessments are necessary. Family/caregiver involvement and cross-service organisation/collaboration represent other important adaptations.

Effects of Texas State Agency Integration on Mental Health Service Use Among Individuals with Co-occurring Cognitive Disabilities and Mental Health Conditions

This study uses Texas's 2017 integration of the state disability and mental health agencies as a case study, combining interviews with Texas agency and advocacy organization leaders to examine perceptions of agency integration and augmented synthetic control analyses of 2014-2020 Medical Expenditure Panel Survey to examine impacts on mental health service use among individuals with co-occurring cognitive disabilities (including intellectual and developmental disabilities) and mental health conditions. Interviewees described the intensive process of agency integration and identified primarily positive (e.g., decreased administrative burden) impacts of integration. Quantitative analyses indicated no effects of integration on receipt of mental health-related services among people with co-occurring conditions. While leaders identified some potentially beneficial impacts of state agency integration, the limited impact of integration beyond the agency suggests that interventions at multiple levels of the service system, including those targeting providers, are needed to better meet the mental health service needs for this population.

Childhood risk factors and clinical and service outcomes in adulthood in people with intellectual disabilities

BACKGROUND

Adults with intellectual disability experience increased rates of mental health disorders and adverse mental health outcomes.

AIM

Explore childhood risk factors associated with adverse mental health outcomes during adulthood as defined by high cost of care, use of psychotropic medication without a severe mental illness and psychiatric hospital admissions.

METHOD

Data on 137 adults with intellectual disability were collected through an intellectual disability community service in an inner London borough. Childhood modifiable and non-modifiable risk factors were extracted from records to map onto variables identified as potential risk factors. Logistic and linear regression models were employed to analyse their associations with adverse outcomes.

RESULTS

We showed that the co-occurrence of intellectual disability with autism spectrum disorder and/or attention-deficit hyperactivity disorder (ADHD) were associated with psychotropic medication use and high-cost care packages. However, when challenging behaviour during childhood was added, ADHD and autism spectrum disorder were no longer significant and challenging behaviour better explained medication prescribing and higher cost care. In addition, the severity of intellectual disability was associated with higher cost care packages. Ethnicity (Black and mixed) also predicted higher cost of care.

CONCLUSIONS

Challenging behaviour during childhood emerged as a critical variable affecting outcomes in young adulthood and mediated the association between adult adverse mental health outcomes and co-occurring neurodevelopmental conditions, that is, ADHD and autism. These findings emphasise the need for effective early intervention strategies to address challenging behaviour during childhood. Such interventions for challenging behaviour will need to take into consideration autism and ADHD.

Primary mental healthcare for adults with mild intellectual disabilities: Patients' perspectives

BACKGROUND

People with mild intellectual disabilities (MID) experience more mental health (MH) problems than the general population but often do not receive appropriate primary MH care. Primary MH care is essential in integrative MH care and, therefore, demands high quality. To improve primary MH care for this patient group, account must be taken of the experiences of people with MID. So far, their perspectives have been largely absent from primary MH care research.

OBJECTIVES

To explore patients' experiences, needs, and suggestions for improvement regarding primary MH care for people with MID.

METHODS

Qualitative study among adults with MID who visited their GP with MH problems in the previous 12 months. Semi-structured interviews were conducted using a guide based on Person-Centred Primary Care Measures. Transcripts were analysed thematically.

RESULTS

The 11 interviews that we conducted revealed four themes. The first theme, cumulative vulnerability, describes the vulnerability - instigated by the MID and reinforced by MH problems - experienced on a GP visit. The other themes (needs regarding the GP, needs regarding the network, self-determination) arise from this vulnerability.

CONCLUSION

People with both MID and MH problems are extra vulnerable in primary care but desire self-determination regarding their MH care trajectory. This requires investment in a good GP-patient relationship and the organisation of additional support to meet these patients' needs, for which collaborative care with the patient, the patient's network, and other (care) professionals is of utmost importance.

Primary mental health care for adults with mild intellectual disabilities: a focus group study of care professionals' perspectives

BACKGROUND

GPs and mental health nurse practitioners (MHNPs) often feel ill equipped to provide mental health (MH) care to people with mild intellectual disabilities (MID). This is worrying, as insufficient primary MH care may lead to more severe or chronic problems. To improve primary MH care for this patient group, account must be taken of the experiences and needs of GPs and MHNPs providing the care.

AIM

To explore GPs' and MHNPs' experiences, needs, and recommendations for improvement regarding primary MH care for adults with MID.

DESIGN & SETTING

A qualitative study was undertaken using focus groups with GPs and MHNPs in the Netherlands.

METHOD

The focus groups were guided by topics based on an interview study with adults with MID receiving primary MH care. Transcripts were analysed by thematic analysis.

RESULTS

Four focus groups, with 19 GPs and nine MHNPs, revealed four themes describing the needs and perceived complexity involved in providing MH care to patients with both MID and MH problems: (1) GPs' and MHNPs' struggles with adapting to challenging patient characteristics; (2) importance and difficulties of establishing a good doctor-patient relationship; (3) facilitating and hampering roles of the patient's network; and (4) GPs' and MHNPs' challenges to provide care in the healthcare chain.

CONCLUSION

GPs and MHNPs often experience providing care and support to this patient group as burdensome. It is important to consider the MID throughout the MH trajectory, to invest in a strong doctor-patient relationship, and to establish a stable, sustainable network and coordinated collaborative care around the patient.

Primary care experiences of adults reporting learning disability: a probability sample survey

BACKGROUND

Adults with learning disability face multiple adversities, but evidence on their needs and primary care experiences is limited.

AIM

To compare the characteristics and primary care experiences of adults reporting learning disability with those who did not.

DESIGN AND SETTING

This was an analysis of the 2022 General Practice Patient Survey, a national probability sample survey conducted in 2022 with people registered with NHS primary care in England.

METHOD

This analysis reports descriptive profiles, weighted and with 95% confidence intervals. Logistic regression models adjusting for gender, age, ethnicity, and area-level deprivation compared experiences of adults reporting learning disability with those who did not.

RESULTS

Survey participants comprised 623 157 people aged ≥16 years, including 6711 reporting learning disability. Adults reporting learning disability were more likely to be male, younger, of mixed or multiple ethnicities, and live in more deprived areas. All chronic conditions included in the survey were more common in adults reporting learning disability, especially reported sensory, neurodevelopmental, neurological, and mental health conditions. Adults reporting learning disability were twice as likely to have a preferred GP, and less likely to find their practice's website easy to navigate. They were also less likely to have confidence and trust in their healthcare professional, or feel their needs were met.

CONCLUSION

Adults reporting a learning disability had a higher likelihood of chronic health conditions. Their reported experiences of primary care indicate that, despite recent initiatives to improve services offered, further adaptations to the consistency and ease of access to primary care is needed.

Association Between Psychological Distress and Coping Styles in Family Caregivers of People with Intellectual Disability or Chronic Mental Disorder in Mongolia

Around the world, family caregivers are an important source of support for people with intellectual disability (ID) and for those with severe mental disorder (SMD), although the level of support can be influenced by the culture and government healthcare systems in each country. However, there is little evidence about the mental health and coping mechanisms of these caregivers in low-income countries. To address this need, we aimed to elicit whether there are potential links between coping style, mental health, and perceived burden experienced by this group, using a sample from a central Asian upper middle-income country.

METHODS

We recruited 120 participants, of which 60 were caregivers of people with ID and 60 of people with SMD. All participants were recruited from Ulaanbaatar, the capital city of Mongolia, Central Asia, and were asked to complete of the Depression, Anxiety and Stress Scale (DASS) and the Coping Orientation to Problems Experienced inventory scale (COPE). Multiple regression analyses were used to investigate associations between these measures.

RESULTS

We found that DASS scores were significantly higher among the sample of caregivers of individuals with ID than in those of SMD. Mental and behavioral disorders were associated with higher DASS scores in the sample of caregivers of those with SMD. Good coping styles, indicated by higher scores in the COPE, were associated with increased age in caregivers of individuals with ID.

CONCLUSION

Although overall the carers of people with SMD appeared to have better active coping skills and better acceptance of the caring role, they demonstrated comparatively high levels of stress. This study was not registered.

Navigating Unique Intersectional Experiences: LGBTQ+ Community Organisations Addressing Individuals With Intellectual Disabilities' Needs

BACKGROUND

This exploratory study aimed to enhance the understanding of practitioners' experiences within LGBTQ+ community organisations when providing interventions for LGBTQ+ individuals with intellectual disabilities. Three specific objectives were outlined: to document the situations and challenges encountered by practitioners; to identify perceived needs among LGBTQ+ individuals with intellectual disabilities and to elicit their suggestions for recommendations to improve services.

METHOD

A qualitative approach, involving in-depth interviews with 12 Québec-based LGBTQ+ community practitioners, underwent content analysis.

RESULTS

Findings were organised around three themes: perceived support needs of LGBTQ+ people with intellectual disabilities; challenges experienced in intervention and recommendations to improve services. Findings reveal that practitioners frequently face significant challenges when supporting LGBTQ+ individuals with intellectual disabilities, who often struggle with multiple daily challenges and insufficient support.

CONCLUSIONS

The study highlights the need to empower LGBTQ+ organisations with essential skills and foster partnerships with public service staff to ensure a more inclusive, intersectional approach.

Health Service Utilization Patterns Among Medicaid Enrollees With Intellectual and Developmental Disabilities Before and During the COVID-19 Pandemic: Implications for Pandemic Response and Recovery Efforts

OBJECTIVES

To assess the impact of COVID-19 on health service utilization of adults with intellectual and developmental disabilities (IDDs) through an analysis of Medicaid claims data.

DESIGN

Retrospective cohort study of Medicaid claims.

SETTING AND PARTICIPANTS

Medicaid members aged 25 to 64 years from January 1, 2018, to March 31, 2021, from the states of Louisiana, Pennsylvania, and Wyoming.

INTERVENTION

We analyzed data from two 12-month time periods (pre-COVID-19 and during COVID-19) and assessed the potential impact of the COVID-19 pandemic on health service utilization and service intensity for 3 cohorts: (1) IDD with preexisting mental health diagnoses, (2) IDD without mental health diagnoses, and (3) all other Medicaid members.

MAIN OUTCOME MEASURE

Health service utilization determined by specific claims data classifications.

RESULTS

The analysis showed reduced utilization for nonmental health service types with differing utilization patterns for IDD with preexisting mental health diagnoses, IDD without mental health diagnoses, and all other Medicaid members. Change in utilization varied, however, for mental health service types. Measures of service intensity showed decreased numbers of members utilizing services across most service types and increased Medicaid claims per person across most mental health service categories but decreased Medicaid claims per person for most nonmental health services.

CONCLUSIONS

Results suggest a need for mental health services among all Medicaid members during the COVID-19 pandemic. By anticipating these needs, communities may be able to expand outreach to Medicaid members through enhanced case management, medication checks, and telemedicine options.

Differences and similarities between children and adolescent exposed to interpersonal traumas with and without Intellectual Disability: An explorative study

BACKGROUND

Individuals with intellectual disability (ID) are more vulnerable to traumatic and stressful events, increasing their risk of developing post-traumatic stress disorder (PTSD).

AIMS

This study aimed to investigate differences in psychopathology, post-traumatic symptoms, and adaptive functioning in a sample of Italian children and adolescents with and without ID. It also sought to determine whether the type of interpersonal trauma was associated with distinct psychopathological outcomes.

METHODS AND PROCEDURES

Sixty-six children and adolescents exposed to interpersonal trauma (physical/sexual abuse, domestic violence, and neglect), were selected and divided into two groups based on the presence or absence of ID. Assessment consisted of structured parent interviews and parent-reported questionnaires. For each scale, comparisons between subtests were performed.

OUTCOMES AND RESULTS

Children and adolescents with ID were more likely to exhibit more severe post-traumatic symptoms, anxiety issues, social problems, and poorer adaptive functioning, with the exception of the practical domain, which appeared to be equally impaired in both groups. In terms of interpersonal trauma typology, exposure to physical/sexual abuse and domestic violence led to greater post-traumatic symptoms compared to neglect.

CONCLUSION AND IMPLICATIONS

Interpersonal trauma significantly affects children and adolescents, with or without ID, highlighting the need for tailored treatments for both groups.

Behaviours that Challenge in SATB2-associated Syndrome: Correlates of Self-injury, Aggression and Property Destruction

SATB2-associated syndrome (SAS) is a genetic syndrome characterised by intellectual disability, severe speech delay, and palatal and dental problems. Behaviours that challenge (BtC) are reported frequently; however, there is limited research on specific forms of BtC and the correlates of these behaviours. The current study explores correlates of well-defined BtC, self-injury, aggression, and property destruction, in SAS. Eighty-one parents/caregivers of individuals with SAS (53.1% male, Mage 10.12 years) completed questionnaire measures of health, behavioural, emotional, and autism characteristics. Individuals with SAS were grouped based on caregiver responses to the presence or absence of self-injury, aggression, and property destruction on the Challenging Behaviour Questionnaire. Rates of self-injury, aggression and property destruction were 42%, 77% and 49%, respectively. Between-group comparisons were conducted to compare characteristics between behaviour groups. Significantly differing characteristics were entered into separate hierarchical logistic regressions for each form of BtC. Behavioural comparisons indicated variation in the characteristics associated with each behaviour. All hierarchical logistic regression models were significant (p < .001): self-injury (χ2(5) = 38.46, R2 = 0.571), aggression (χ2(4) = 25.12, R2 = 0.414), property destruction (χ2(4) = 23.70, R2 = 0.346), explaining between 34.6% and 57.1% of the variance in behaviour presence. This is the first study to identify correlates of self-injury, aggression, and property destruction in SAS. Variability in the characteristics associated with each behaviour highlights the importance of specificity when examining BtC. Understanding correlates of specific forms of BtC has important implications for informing SAS-associated pathways to behavioural outcomes and the implementation of tailored behavioural interventions.

Item-validity analysis of the SED-S in a multicentre study of adults with intellectual disabilities

BACKGROUND

Valid and reliable instruments for measuring emotional development are critical for a proper diagnostic assignment in individuals with intellectual disabilities. This exploratory study examined the psychometric properties of the items on the Scale of Emotional Development-Short (SED-S).

METHOD

The sample included 612 adults with intellectual disabilities (Mage = 37.35, SDage = 13.27; 59.8% males). Item validity analysis comprising sensitivity and specificity rates and discriminatory power were determined.

RESULTS

The relative mean frequency of 'yes' answers to all 200 items was 29.5%. The mean sensitivity rate was 67.5% and the mean specificity rate was 79.3%. Most items (85.0%) showed good discriminatory power with the adjacent stage(s), especially between SED-1, SED-2, SED-3 and SED-4. Particularly in SED-4 some items showed weaknesses in the differentiation between these stages.

DISCUSSION

This study adds to previous validation studies by showing that most SED-S items have psychometrically sound properties.

A Scoping Review of the Intersectionality of Autism and Intellectual and Developmental Disability with Social Inequity on Diagnosis and Treatment of Youth

Objective: To describe how the intersectionality of race, ethnicity, and language with autism and intellectual and developmental disability (IDD) impacts mental health inequities in psychopharmacological management of youth. Method: This was a scoping review in which a series of searches were conducted in PubMed, Web of Science, Google Scholar, and manual review of the articles collected. Results: Although autism and/or IDD increases the risk for poor physical and mental health, social determinants of health such as race, ethnicity, and language account for approximately a third of poor outcomes. Minoritized children with autism/IDD experience significantly greater delays to diagnosis and misdiagnosis and are less likely to receive appropriate services. Access to psychological testing and psychosocial services is often limited by availability, skilled practitioners, a shortage of non-English-language providers or interpreters, and poor reimbursement. Conclusion: The intersectionality of autism and/or IDD with race, ethnicity, and language compounds the health inequities associated with either of these challenges independently.

IDcare - a longitudinal register study of pre-pandemic and pandemic health care utilization and diagnostic profiles among people with intellectual disabilities in southern Sweden

The aim of the creation of this cohort was to investigate patterns of health and health care utilisation before and during the COVID-19 pandemic, overall and in relation to specific diagnoses, among people with intellectual disabilities (ID) compared to the general population. People living in Skåne, the southernmost region of Sweden, on 1st of January 2014 with at least one diagnosis of ID (ICD-10 codes F70-F79) or Down syndrome (DS; Q90), or support and/or services according to the LSS act comprised the ID cohort (n = 14 716). People living in the same family and/or household as a person in the ID cohort constituted the ID family cohort (n = 31 688), and those remaining comprised the general population cohort (gPop; n = 1 226 955). Data has been collected for all three cohorts from several national and regional registers. These include registers for health care (2014-2021), deaths (2014-2021), COVID-19-related health care (vaccinations, intensive care, palliative care, 2020-2021). The prevalence of ID was 1.2%. In the ID cohort, 77.9% had at least one measure of support, 5.8% at least one Q90-diagnosis and 63.8% had at least one F7-diagnosis (26.9% mild (F70), 7.4% moderate (F71), 2.8% severe (F72), 1.4% profound (F73), and 25.4% other/unknown (F78/F79)). Compared to the gPop there were more people in the younger age groups in the ID cohort. At this point, no additional collection of data will be carried out. However, there is a possibility to add data from the registers to include years after 2021 or from additional registers. Future publications will explore relevant research questions and report key findings in relation to health among people with ID. Future results will be used to inform policy and practice on people with ID.

Validation of the Scale of Emotional Development-Short (SED-S) in Healthy Adults with an Intellectual Disability

Background: The Scale of Emotional Development-Short (SED-S) assesses the level of emotional development (ED) of persons with intellectual disability (ID) in eight domains across five stages with reference ages from 0 to 12 years. The aim of this study was to apply and validate the SED-S in a sample of healthy adults with ID. Method: Eighty-three mentally healthy adults with ID were assessed using the SED-S. Factor analysis, Cronbach's alpha, and correlational analyses were used to test the scale's internal structure and associations. Results: The results showed that the eight-domain structure of the SED-S is supported by strong inter-domain correlations, a high Cronbach's alpha, and a one-factor confirmatory factor analysis. The SED-S was associated with the severity of ID but not with age or gender. Conclusions: The SED-S can be used in non-clinical settings to better understand and meet the emotional needs of adults with ID.

Autism and psychopathology - prevalence, identification, and symptoms equivalence: study protocol

Objective

Despite increasing evidence of high psychopathological vulnerability in people with Autism Spectrum Disorder (ASD) and/or Intellectual disability (ID), comprehensive data on prevalence and presentation of psychiatric disorders (PD) in people with significant cognitive and communication impairment are lacking. The extent to which PD can present with behavioral/observable symptoms and include Problem Behaviors (PB) has also been scarcely evaluated through population-based studies. The paper presents the protocol of a cross-sectional study aimed at filling these gaps, referred to a large multicentric Italian population-based sample of adolescents and adults.

Methods

A battery of validated scales, SPAIDD, DASH-II, DiBAS-R, and STA-DI, is used to support and control for clinical diagnoses of PD. Study population is stratified according to different independent variables such as the severity of ID and ASD, gender, age group, and source of recruitment. A network analysis will be carried out to identify the most central behavioral symptoms for the various PD and their relationship with PB. Overlap between psychiatric symptoms and ASD and ID phenotypes is also addressed.

Results and Conclusion

This study should provide valuable insight into better diagnostic accuracy, leading to well-informed interventions to improve the quality of life of people with ASD and/or ID.

Barriers to Mental Health Care Transition for Youth and Young Adults with Intellectual and Developmental Disabilities and Co-occurring Mental Health Conditions: Stakeholders' Perspectives

Youth and young adults (YYA) with intellectual and developmental disabilities (IDD) have high rates of co-occurring mental health (MH) conditions. The time during transition from pediatric to adult health and mental health care can be a very challenging, with risk of loss of services leading to poor outcomes. This study aimed to explore barriers to transition from pediatric to adult health and mental health care and services for individuals with IDD and co-occurring MH conditions, by eliciting the view of stakeholders, including disability advocates. Qualitative analysis was conducted using grounded theory, and themes were coded based upon the social-ecological model (SEM). We generated themes into multiple levels: the individual level, the family level, the provider level, the systems of care level, and the societal level. Stakeholders expressed a critical need to improve coordination between systems, and to increase provider availability to care for YYA with IDD and co-occurring MH conditions.

Interagency Coordination to Manage Co-Occurring Intellectual and Developmental Disabilities and Mental Health Conditions

OBJECTIVE

The authors aimed to identify barriers to and strategies for supporting coordination between state agencies for intellectual and developmental disability (IDD) or mental health to meet the mental health needs of people with co-occurring IDD and mental health conditions.

METHODS

Forty-nine employees of state agencies as well as advocacy and service delivery organizations across 11 U.S. states with separate IDD and mental health agencies were interviewed between April 2022 and April 2023. Data were analyzed with a thematic analysis approach.

RESULTS

Interviewees reported that relationships between the IDD and mental health agencies have elements of both competition and coordination and that coordination primarily takes place in response to crisis events. Barriers to interagency coordination included a narrow focus on the populations targeted by each agency, within-state variation in agency structures, and a lack of knowledge about co-occurring IDD and mental health conditions. Interviewees also described both administrative (e.g., memorandums of understanding) and agency culture (e.g., focusing on whole-person care) strategies that are or could be used to improve coordination to provide mental health services for people with both IDD and a mental health condition.

CONCLUSIONS

Strategies that support state agencies in moving away from crisis response toward a focus on whole-person care should be prioritized to support coordination of mental health services for individuals with co-occurring IDD and mental health conditions.

Impact of the emotional development approach on psychotropic medication in adults with intellectual and developmental disabilities: a retrospective clinical analysis

BACKGROUND

Compared with the general population, adults with an intellectual developmental disorder (IDD) are more likely to develop mental health problems and to receive high levels of psychotropic medication, particularly antipsychotics. The emotional development (ED) approach may help to better understand the nature of challenging behaviour (CB) and tailor treatment and support accordingly. The aim of this retrospective study was to investigate the impact of the ED approach on the prescription of psychotropic medication during inpatient psychiatric treatment.

METHODS

The clinical data of 1758 patients were analysed within a retrospective study design over a period of 12 years. ED level was assessed (1) for the first time (INITIAL-SEO), (2) during a previous hospital stay (PAST-SEO) or (3) not at all (NO-SEO). The effects of the ED assessment and the respective intervention during the current admission on the number of psychotropics and the number and dosage of antipsychotics were analysed for the total sample, including those with CB, autism spectrum disorders and psychosis. Group differences were analysed by a chi-square test and a one-factorial analysis of variance. For analysing the impact of the application of the ED approach on psychotropic medication, a covariance model was applied. Changes between the subsamples were analysed by t-tests for dependent samples.

RESULTS

The ED approach had a significant impact on reducing the overall amount of psychotropic medication and the dosage of antipsychotics in all patients with IDD. These effects were mainly attributable to those showing CB. In patients with autism spectrum disorders, the developmental approach reduced the number of antipsychotics. No effects could be observed in patients with psychosis; in this subsample, both the number and dosage of antipsychotics increased.

CONCLUSIONS

The application of the ED approach in the current hospital stay reduced the number of psychotropic drugs and the number and dosage of antipsychotics, especially in those patients with IDD and CB, but also in those with autism spectrum disorders.

Diagnosis and pharmacological management of attention deficit hyperactivity disorder in adults with and without intellectual disability: cohort study using electronic health records

BACKGROUND

Attention deficit hyperactivity disorder (ADHD) is increasingly diagnosed in adults. People with intellectual disability have higher rates of ADHD yet there is little evidence on the presentation and pharmacological treatment of ADHD in this population or how this differs from the general population.

METHODS

Retrospective cohort study using data from electronic health records. Adults with intellectual disability newly diagnosed with ADHD between 2007 and 2022 were matched to adults with ADHD without intellectual disability and their clinical features and treatments were compared.

RESULTS

A total of 159 adults with ADHD and intellectual disability and 648 adults with ADHD without intellectual disability formed the dataset. Adults with intellectual disability had higher rates of psychiatric co-morbidity and spent more time under mental health services than those without intellectual disability. They were more likely to have recorded agitation, aggression, hostility, and mood instability, and less likely to have poor concentration recorded in the 12 months prior to the diagnosis of ADHD. Following diagnosis, people with intellectual disability were significantly less likely to be prescribed any medication for ADHD than controls without intellectual disability (adjusted odds ratio 0.60, 95% confidence interval 0.38-0.91), and were less likely to be prescribed stimulants (27.7% v 46.0%, p < 0.001).

CONCLUSIONS

The presence of behaviors that challenge in adults with intellectual disability may indicate co-occurring ADHD. Further work to define the safety and efficacy of medication for ADHD in adults with intellectual disability is needed to understand differences in prescription rates and to avoid inequities in care outcomes.

World Psychiatric Association-Asian Journal of Psychiatry Commission on Public Mental Health

Although there is considerable evidence showing that the prevention of mental illnesses and adverse outcomes and mental health promotion can help people lead better and more functional lives, public mental health remains overlooked in the broader contexts of psychiatry and public health. Likewise, in undergraduate and postgraduate medical curricula, prevention and mental health promotion have often been ignored. However, there has been a recent increase in interest in public mental health, including an emphasis on the prevention of psychiatric disorders and improving individual and community wellbeing to support life trajectories, from childhood through to adulthood and into older age. These lifespan approaches have significant potential to reduce the onset of mental illnesses and the related burdens for the individual and communities, as well as mitigating social, economic, and political costs. Informed by principles of social justice and respect for human rights, this may be especially important for addressing salient problems in communities with distinct vulnerabilities, where prominent disadvantages and barriers for care delivery exist. Therefore, this Commission aims to address these topics, providing a narrative overview of relevant literature and suggesting ways forward. Additionally, proposals for improving mental health and preventing mental illnesses and adverse outcomes are presented, particularly amongst at-risk populations.

Decision-making regarding social situations in people with intellectual disability at different stages of the decision-making process

Decision-making capability is essential in fulfilling the need for autonomy of people with intellectual disability. In this study we aimed to examine decision-making capability regarding important social situations in people with intellectual disability at different stages of decision-making process. We studied 80 vocational school students with mild intellectual disability and 80 students of a similar age from mass vocation schools. We assessed decision-making with Important Life Decisions Task (ILDT). Students with intellectual disability obtained significantly lower scores than controls for each of the stories in ILDT as in each stage and overall final score in the decision-making process. The magnitude of difference in scores between groups varied in different stages of decision-making process. The most notable difficulties in decision-making regarding important social situations in people with intellectual disability are related to the evaluation of alternatives stage. Pattern of differences obtained in our study may be related to the content of decision-making problems.

The utility of behavioral activation therapy in addressing emotional problems of two depressed students with borderline intellectual disability: A case study

PURPOSE

Intellectual disability is one of the neurodevelopmental disorders. Studies indicated that depression and anxiety are the most prevalent emotional problems among the people with intellectual disability. The aim of this study was to investigate the utility of behavioral activation therapy in addressing emotional problems of two depressed students with borderline intellectual disability.

METHOD

This study is a single-subject design with multiple baseline and one month follow-up. Two students with borderline intelligence underwent behavioral activation therapy for 12 sessions. Beck Depression Inventory-Second Edition, Beck Anxiety Inventory, Oxford Happiness Inventory and Rosenberg Self-Esteem Scale were used. Data were analyzed using visual inspection of graphed data, changes in trends, improvement percentage and effect size.

FINDINGS

The findings of this study support the utility of behavioral activation therapy in addressing the emotional problems of two depressed students with borderline intellectual disability.

CONCLUSION

Behavioral activation therapy has had favorable outcomes in reducing depression and anxiety in depressed students with borderline 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.

Psychiatric care for people with Prader-Willi syndrome-characteristics, needs and barriers

BACKGROUND

Prader-Willi syndrome (PWS) is commonly associated with intellectual disability, but also with a specific behavioural phenotype and a high predisposition to psychiatric comorbidity. This study examines the psychiatric care situation of people with PWS.

METHOD

A structured online questionnaire was administered to carers of people with PWS living in Germany, asking about demographic, diagnostic and treatment parameters as well as personal experiences.

RESULTS

Of 77 people with PWS, 44.2% had at least one psychiatric comorbid diagnosis. The main reasons for seeking psychiatric care were emotional outbursts and aggressive behaviour. 34.9% reported that they were currently seeking psychiatric care without success. However, 32.5% of PWS had been treated with psychotropic medication, mainly antipsychotics.

CONCLUSIONS

Psychiatric comorbidity appears to be undertreated in PWS, especially in the ambulatory setting. Uncertainty among mental health care providers may also lead to frequent off-label use of psychotropic medications.

Mental and Behavioral Health, and Crisis Services for People with Intellectual and Developmental Disabilities in Medicaid Home- and Community-Based Services

People with intellectual and developmental disabilities (IDD) often have higher rates of comorbid mental health conditions compared to the general population. Yet, many people with IDD also have unmet needs for mental and behavioral health services. The aim of this study was to examine how states provided mental and behavior health, and crisis services to people with IDD in their Home- and Community-Based Services (HCBS) programs, the largest funding mechanism for Long-Term Services and Supports (LTSS) for people with IDD in the United States. We analyzed fiscal year (2021) Medicaid HCBS waivers for people with IDD from across the United States to examine if and how they provided mental and behavior health, and crisis services. States projected spending $968.9 million for mental and behavior health, and crisis services for 190,299 people with IDD. Applied behavior analysis services were provided at greater rates than positive behavior supports and other forms of behavior interventions. While most states provided mental and behavior health, and crisis services in their waivers, there were vast inconsistencies in how they did so, across states, waivers, and services. HCBS are a crucial safety net to ensure people with IDD, especially those who also have mental health disabilities, can live and thrive in their communities.

Bias in assessment of co-occurring mental disorder in individuals with intellectual disabilities: Theoretical perspectives and implications for clinical practice

Influence from bias is unavoidable in clinical decision-making, and mental health assessment seems particularly vulnerable. Individuals with intellectual disabilities have increased risk of developing co-occurring mental disorder. Due to the inherent difficulties associated with intellectual disabilities, assessment of mental health in this population often relies on a different set of strategies, and it is unclear how these may affect risk of bias. In this theoretical paper, we apply recent conceptualisations of bias in clinical decision-making to the specific challenges and strategies in mental health assessment in intellectual disabilities. We suggest that clinical decision-making in these assessments is particularly vulnerable to bias, including sources of bias present in mental health assessment in the general population, as well as potential sources of bias which may be specific to assessments in this population. It follows that to manage potential bias, triangulating information from multi-informant, multi-method, interdisciplinary assessment strategies is likely to be necessary.

Efficacy of clozapine versus standard treatment in adult individuals with intellectual disability and treatment-resistant psychosis (CLOZAID): study protocol of a multicenter randomized clinical trial

Background

Intellectual disability (ID) affects approximately 1% of the worldwide population and individuals with ID have a higher comorbidity with mental illness, and specifically psychotic disorders. Unfortunately, among individuals with ID, limited research has been conducted since ID individuals are usually excluded from mental illness epidemiological studies and clinical trials. Here we perform a clinical trial to investigate the effectiveness of clozapine in the treatment of resistant psychosis in individuals with ID. The article highlights the complexity of diagnosing and treating psychopathological alterations associated with ID and advocates for more rigorous research in this field.

Methods

A Phase IIB, open-label, randomized, multicenter clinical trial (NCT04529226) is currently ongoing to assess the efficacy of oral clozapine in individuals diagnosed with ID and suffering from treatment-resistant psychosis. We aim to recruit one-hundred and fourteen individuals (N=114) with ID and resistant psychosis, who will be randomized to TAU (treatment as usual) and treatment-with-clozapine conditions. As secondary outcomes, changes in other clinical scales (PANSS and SANS) and the improvement in functionality, assessed through changes in the Euro-QoL-5D-5L were assessed. The main outcome variables will be analyzed using generalized linear mixed models (GLMM), assessing the effects of status variable (TAU vs. Clozapine), time, and the interaction between them.

Discussion

The treatment of resistant psychosis among ID individuals must be directed by empirically supported research. CLOZAID clinical trial may provide relevant information about clinical guidelines to optimally treat adults with ID and treatment-resistant psychosis and the benefits and risks of an early use of clozapine in this underrepresented population in clinical trials.

Pattern of multimorbidity in middle-aged and older-aged people with mild intellectual disability in Australia

BACKGROUND

Non-communicable diseases (NCDs), also known as chronic diseases, now constitute a major proportion of ill-health across most adult and older populations including in people with intellectual disability. The current paper is a comparative analysis of prevalence of NCDs across mid-aged and older-aged people with mild intellectual disability.

METHOD

Comparative data comes from two cross-sectional surveys using similar methodology and timeframes. The analysis sample comprises mid-aged group (30-50 years, N = 291) and older-aged group (≥60 years, N = 391).

RESULTS

People with mild intellectual disability start developing NCDs in early to mid-adulthood and increases with age. The mean number of NCDs in mid-aged group was 0.86 (SD, 0.84) compared to 3.82 in older group (SD, 2.67).

CONCLUSION

There needs to be early identification and management of NCDs using relevant health promotion and preventative measures at optimal intervention points. The training of healthcare professionals needs improvement.

Mental health, challenging behaviour, diagnosis, and access to employment for people with intellectual disabilities in Norway

BACKGROUND

Studies have found that presence of challenging behaviours and mental health problems limits employment for people with intellectual disabilities. This study investigates the associations between age, gender, living condition, level of intellectual disability, diagnoses, behaviour, mental health, and employment in adults with intellectual disabilities in Norway.

METHOD

A cross-sectional community-based survey including 214 adult participants (56% men) with intellectual disabilities.

RESULTS

In our sample, 25% had no organised day activity, 27% attended non-work day care, 19% attended sheltered employment, or day care with production, without pay and 29% worked in paid sheltered employment. One participant attended mainstream employment. Moderate and severe/profound level of intellectual disability, possible organic condition and irritability significantly reduced the odds of employment (paid and unpaid).

CONCLUSION

Findings suggest unequal access to the sheltered employment that was meant to be inclusive. More individualised evaluation of prerequisites is suggested to further facilitate employment for this group.

A brief version of the Scale of Emotional Development - Short

BACKGROUND

The Scale of Emotional Development - Short (SED-S) captures the level of emotional development in persons with a disorder of intellectual development (DID) with 200 items on five developmental levels. The study aims to develop a brief version of the SED-S.

METHODS

Based on item analysis (proportions, χ2 -test, Spearman's ρ and corrected item-total correlation), a brief version of the SED-S was developed in a sample of 224 adults with a DID (n1 ) and validated in a second independent matched sample (n2  = 223).

RESULTS

Item reliability ranged per item set from Cronbach's α = 0.835 to 0.924. Weighted kappa resulted in κω  = 0.743 (P < 0.001, 95% confidence interval = 0.690-0.802). Overall agreement of the brief version with the original SED-S was PO  = 0.7. The brief version of the SED-S showed weaknesses in distinguishing level 2 from the adjacent levels.

CONCLUSIONS

The brief version of the SED-S showed good reliability and moderate to good validity results. Items of phase 2 and, to some degree, of phase 5 should be revised to further improve the psychometric properties of the scale.

Experiences of health care services among people with cognitive disabilities and mental health conditions

BACKGROUND

People with cognitive disabilities such as intellectual and developmental disabilities face significant barriers to accessing high-quality health care services. Barriers may be exacerbated for those with co-occurring mental health conditions.

OBJECTIVE

This study compares patient experiences of health care services between adults with and without cognitive disabilities and, among people with a cognitive disability, those with and without co-occurring mental health conditions.

METHODS

Cross-sectional analyses were conducted using 2021 Medical Expenditure Panel Survey data, a national U.S. survey, to examine differences in Consumer Assessment of Healthcare Providers and Systems measures.

RESULTS

Adults with cognitive disabilities reported lower satisfaction with health care services compared to the general population (7.62 (95% confidence interval (CI): 7.41-7.83) vs. 8.33 (95% CI: 8.29-8.38) on scale from 0 to 10). Adults with cognitive disabilities were less likely to report that providers listened carefully to them (odds ratio (OR): 0.55, 95% CI: 0.42-0.71), explained things in a way that was easy to understand (OR: 0.48, 95% CI: 0.35-0.66), showed respect for what they had to say (OR: 0.38, 95% CI: 0.29-0.51), spent enough time with them (OR: 0.52, 95% CI: 0.40-0.69), or gave advice that was easy to understand (OR: 0.40, 95% CI: 0.28-0.58) compared to the general population. Among adults with cognitive disabilities, there were no differences based on co-occurring mental health conditions.

CONCLUSIONS

Adults with cognitive disabilities report lower satisfaction with health care services driven by worse experiences with the health care system. Policies to increase provider capacity to support this population should be prioritized.

Developing and Implementing a Web-Based Branching Logic Survey to Support Psychiatric Crisis Evaluations of Individuals With Developmental Disabilities: Qualitative Study and Evaluation of Validity

BACKGROUND

Individuals with developmental disabilities (DD) experience increased rates of emotional and behavioral crises that necessitate assessment and intervention. Psychiatric disorders can contribute to crises; however, screening measures developed for the general population are inadequate for those with DD. Medical conditions can exacerbate crises and merit evaluation. Screening tools using checklist formats, even when designed for DD, are too limited in depth and scope for crisis assessments. The Sources of Distress survey implements a web-based branching logic format to screen for common psychiatric and medical conditions experienced by individuals with DD by querying caregiver knowledge and observations.

OBJECTIVE

This paper aims to (1) describe the initial survey development, (2) report on focus group and expert review processes and findings, and (3) present results from the survey's clinical implementation and evaluation of validity.

METHODS

Sources of Distress was reviewed by focus groups and clinical experts; this feedback informed survey revisions. The survey was subsequently implemented in clinical settings to augment providers' psychiatric and medical history taking. Informal and formal consults followed the completion of Sources of Distress for a subset of individuals. A records review was performed to identify working diagnoses established during these consults.

RESULTS

Focus group members (n=17) expressed positive feedback overall about the survey's content and provided specific recommendations to add categories and items. The survey was completed for 231 individuals with DD in the clinical setting (n=161, 69.7% men and boys; mean age 17.7, SD 10.3; range 2-65 years). Consults were performed for 149 individuals (n=102, 68.5% men and boys; mean age 18.9, SD 10.9 years), generating working diagnoses to compare survey screening results. Sources of Distress accuracy rates were 91% (95% CI 85%-95%) for posttraumatic stress disorder, 87% (95% CI 81%-92%) for anxiety, 87% (95% CI 81%-92%) for episodic expansive mood and bipolar disorder, 82% (95% CI 75%-87%) for psychotic disorder, 79% (95% CI 71%-85%) for unipolar depression, and 76% (95% CI 69%-82%) for attention-deficit/hyperactivity disorder. While no specific survey items or screening algorithm existed for unspecified mood disorder and disruptive mood dysregulation disorder, these conditions were caregiver-reported and working diagnoses for 11.7% (27/231) and 16.8% (25/149) of individuals, respectively.

CONCLUSIONS

Caregivers described Sources of Distress as an acceptable tool for sharing their knowledge and insights about individuals with DD who present in crisis. As a screening tool, this survey demonstrates good accuracy. However, better differentiation among mood disorders is needed, including the addition of items and screening algorithm for unspecified mood disorder and disruptive mood dysregulation disorder. Additional validation efforts are necessary to include a more geographically diverse population and reevaluate mood disorder differentiation. Future study is merited to investigate the survey's impact on the psychiatric and medical management of distress in individuals with DD.

Use of ECT in Autism Spectrum Disorder and/or Intellectual Disability: A Single Site Retrospective Analysis

Autism spectrum disorder (ASD) and intellectual disability (ID) are heterogenous and prevalent conditions which may occur in isolation or as a co-morbidity. Psychiatric co-morbidity is common with limited treatment options. Preliminary research into electroconvulsive therapy (ECT) for these conditions has been encouraging. Thus, further research in this patient population is warranted. We conducted a 10-year retrospective review of the electronic medical record and identified intellectually capable individuals with ASD (IC-ASD), and those with ASD+ID or ID who received at least three ECT treatments. 32 patients were identified of which 30 (94%) experienced positive clinical response, defined as a clinical global impression-improvement (CGI-I) score of 3 or less. The average retrospective CGI-I score across all groups was 1.97, and results of a t-test performed on CGI-I scores indicated improvement across all groups [t = - 16.54, df = 31, p < 0.001, 95% CI = (1.72, 2.22)]. No significant adverse events were identified based on clinical documentation. Our findings further support previous ECT research in this patient population.

Better at home or in residential care? Victimization of people with intellectual disabilities at the hands of caregivers

BACKGROUND

People with intellectual disabilities often need assistance of some kind in their everyday life. Support needs can increase the risk of their victimization at the hands of professional and family caregivers. This paper explores the differences in caregiver victimization between participants living in residential care settings and those who are not.

METHOD

A sample of 260 adults (59.2 % men) with an intellectual disability diagnosis were assessed using an adaptation of the Juvenile Victimization Questionnaire comparing prevalence, sum and variety scores.

RESULTS

More than half of the sample (59.2 %) experienced some form of caregiver victimization throughout their lifetime, with physical abuse, verbal abuse, and neglect being the most frequently reported forms. Participants in residential care settings experienced significantly more caregiver victimization incidents and a broader range of victimization forms than their counterparts outside residential care. Significant differences were found based on the individuals' place of residence and gender. Details are provided on the last victimization incident, the perpetrator, the psychological and physical consequences of the victimization, and the reporting rates.

CONCLUSIONS

This study outlines high rates of lifetime caregiver victimization, with those who live in residential care settings at particular risk. Further research is needed to gain a deeper understanding of the nuances of caregiver victimization and to prevent abuse in caregiving contexts.

Adult psychiatric and psychosocial outcomes of children with mild intellectual disability: a register follow-up of a population-based cohort

BACKGROUND

Very few longitudinal psychiatric and psychosocial outcome studies of children with mild intellectual disability (MID) have been performed.

METHODS

The study group was population based and consisted of 82 individuals, born in 1979-1985 and diagnosed in childhood at ages between 3 and 15 years with MID. In the present study, register data regarding school attendance, employment, economic situation, psychiatric diagnoses and criminal sentences were retrieved for the years 1997-2018, when the individuals were up to 39 years old.

RESULTS

At follow-up, data were obtained for 78 of the 82 individuals (47 male and 31 female). Mean age at follow-up was 36 years. Of the 78 individuals, 57 (73%) had exclusively received education for pupils with MID, but 21 (27%) had graduated from regular education of some sort (at least 9 years). Forty-four (56%) had never been employed, and 34 (44%) had been registered as employed for at least a shorter period. Forty-seven (60%) had received a sick pension at some point in adulthood. Of the 78 individuals, 44 (56%) had any psychiatric disorder recorded and about half of these (n = 21) had had inpatient treatment. A total of 31 of the 44 individuals in psychiatric care (70%) had ID noted as one of their diagnoses. Of the 78 individuals, 48 (62%) had support from the Act concerning Support and Service for Persons with Certain Functional Impairments (Swedish LSS law) as adults. Twenty-one individuals (27%) had had a criminal conviction, of whom five male individuals had been incarcerated.

CONCLUSIONS

Individuals with MID constitute a heterogeneous group with regard to severity of functional impairment, co-occurring psychiatric disorders and need of support from society. Primary health care, psychiatry and habilitation services need to work together in order to meet the multiple needs of this group.

Screening for depression: Psychometric properties of the German version of the Glasgow depression scale for people with a learning disability (individual and carer version)

BACKGROUND

Adults with intellectual disabilities should participate in the diagnostics of their mental health. The Glasgow Depression Scale for people with a Learning Disability (GDS-LD) and its Carer Supplement (GDS-CS) were translated into German and tested.

METHODS

Internal consistency, criterion validity and inter-test reliability were tested in 64 adults with borderline, mild or moderate intellectual disabilities and their carers. Convergent validity was analysed in 57 adults without intellectual disabilities.

RESULTS

Internal consistency was good (α = 0.81) for GDS-LD and acceptable (α = 0.72) for GDS-CS. The GDS-LD did not differentiate between groups with and without depression. The GDS-CS significantly differentiated between these groups. Convergent validity of the GDS-LD was high. The correlation of GDS-LD and GDS-CS was non-significant.

CONCLUSIONS

In its present form the German version of the GDS-LD does not meet the psychometric properties to be used in clinical practice. This leads to the broader question, how to measure depression in people with learning disabilities with the knowledge of the fallibility of existing measures when utilised with this clinical cohort. Also, future studies need to investigate the role of self-rating.

The use of eye-tracking technology as a tool to evaluate social cognition in people with an intellectual disability: a systematic review and meta-analysis

BACKGROUND

Relatively little is known about social cognition in people with intellectual disability (ID), and how this may support understanding of co-occurring autism. A limitation of previous research is that traditional social-cognitive tasks place a demand on domain-general cognition and language abilities. These tasks are not suitable for people with ID and lack the sensitivity to detect subtle social-cognitive processes. In autism research, eye-tracking technology has offered an effective method of evaluating social cognition-indicating associations between visual social attention and autism characteristics. The present systematic review synthesised research which has used eye-tracking technology to study social cognition in ID. A meta-analysis was used to explore whether visual attention on socially salient regions (SSRs) of stimuli during these tasks correlated with degree of autism characteristics presented on clinical assessment tools.

METHOD

Searches were conducted using four databases, research mailing lists, and citation tracking. Following in-depth screening and exclusion of studies with low methodological quality, 49 articles were included in the review. A correlational meta-analysis was run on Pearson's r values obtained from twelve studies, reporting the relationship between visual attention on SSRs and autism characteristics.

RESULTS AND CONCLUSIONS

Eye-tracking technology was used to measure different social-cognitive abilities across a range of syndromic and non-syndromic ID groups. Restricted scan paths and eye-region avoidance appeared to impact people's ability to make explicit inferences about mental states and social cues. Readiness to attend to social stimuli also varied depending on social content and degree of familiarity. A meta-analysis using a random effects model revealed a significant negative correlation (r = -.28, [95% CI -.47, -.08]) between visual attention on SSRs and autism characteristics across ID groups. Together, these findings highlight how eye-tracking can be used as an accessible tool to measure more subtle social-cognitive processes, which appear to reflect variability in observable behaviour. Further research is needed to be able to explore additional covariates (e.g. ID severity, ADHD, anxiety) which may be related to visual attention on SSRs, to different degrees within syndromic and non-syndromic ID groups, in order to determine the specificity of the association with autism characteristics.

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.

Cognitive dysfunction and psychopathology: a cohort study of adults with intellectual developmental disorder

BACKGROUND

Cognitive impairment of intellectual developmental disorders (IDD) is determined by several different combinations of specific cognitive alterations. People with IDD present a rate of mental health problems that is up to 4 times higher than that of the general population. Despite this, the relationship between specific cognitive dysfunctions and co-occurring mental disorders has not been adequately studied. The aim of the present paper is to investigate the association between specific cognitive dysfunctions and specific psychiatric symptoms and syndromes in people with IDD.

METHODS

One hundred and twenty adults with mild to moderate IDD living in residential facilities underwent a clinical and instrumental assessment for specific cognitive and psychopathological features.

RESULTS

Participants with IDD and ASD have significantly lower scores compared to those without respect to who has not the diagnosis on the Processing Speed Index (PSI) and Perceptual Reasoning Index (PRI) on the WAIS-IV and higher time scores on the TMT A. Moreover, there is a significant association between years of hospitalisation and TMT B and TMT B A time scores; the longer a participant with IDD was hospitalised, the worse their performance on the TMT. Although not statistically significant, many psychopathological clusters showed substantial cognitive profiles.

CONCLUSIONS

Although further research is needed, neuropsychological and IQ tests scores seem to be differently associated to various psychopathological conditions co-occurring with IDD, and with ASD especially. Cognitive assessment seems to support diagnosis and treatment of psychopathological co-occurrences in persons with IDD, also in consideration of indirect implications including a better knowledge of the patient's characteristics beyond IQ deficit.
