A Comparison of Referrals With and Without Autism Spectrum Disorder to Forensic Intellectual Disability Services

Although some authors have suggested that there are higher rates of people with Autism Spectrum Disorder (ASD) in forensic and offending groups, systematic studies have not supported the hypothesis. The present study reviewed 477 referrals made to forensic intellectual disability (ID) services in one calendar year. It was found that 10% of referrals had ASD, a figure similar to the general population of people with ID. Those with ASD had similar patterns of offending to those without but they showed a lower prevalence of contact sexual offences and fewer had been previously charged. We concluded that there is no persuasive evidence that ASD is a risk factor for offending or for any particular type of offending.     

Identification of Post-Traumatic Stress Disorder in Individuals with Autism Spectrum Disorder and Intellectual Disability: A Systematic Review

Introduction: autism spectrum disorder (ASD) and intellectual disability (ID) seem to influence the risk of and vulnerability to exposure to trauma and adverse events. While assessment of a psychiatric disorder in ASD and ID generally is challenging, identification of post-traumatic stress disorder (PTSD) seems particularly so, and knowledge does not seem easily accessible. Methods: This article provides a systematic review of studies describing trauma reactions in individuals with both ASD and ID, including studies involving any single case with the combination of ASD, ID, and PTSD. To systematically explore PTSD symptom presentation in the group, all reported symptoms from studies were assigned by DSM-5 criteria. Results: Eighteen studies met the inclusion criteria, eight group studies and 10 case studies. Assessment methodology in studies varied, as did the format of symptom report. DSM-5 criteria provided a useful framework for integrating findings across studies, indicating that PTSD may be identified in individuals with ASD and ID. However, symptoms involving alterations in arousal and negative alterations in thought and behavior seem more easily identified than symptoms of reexperiencing and avoidance. Conclusions: There is an urgent need to identify behavioral equivalents to PTSD symptoms in this group, making it possible to identify warning signs of trauma and abuse even if such incidents are not known to family or professional carers.     

Mood and Anxiety Symptoms in Psychiatric Inpatients with Autism Spectrum Disorder and Depression

Recent reports suggest that individuals with autism spectrum disorders (ASD) may experience depression at a high frequency, yet few published studies address this issue, especially among adults. In the current investigation, we reviewed features of depression and comorbid traits among depressed inpatients with intellectual disabilities (ID) as a function of ASD. A retrospective chart review was performed for 53 inpatients meeting criteria for depression (13 individuals with ASD and ID and 40 matched individuals with ID but without ASD), all of whom had received a diagnosis of depression at the time of discharge from a specialty psychiatric unit for adults with ID. The depression diagnoses were based on a comprehensive clinical assessment; specific mood and anxiety symptoms were reported by informants at the time of intake using the Mood and Anxiety Semi-Structured (MASS) Interview for Patients with Intellectual Disabilities (Charlot, Deutsch, Hunt, Fletcher, & McIlvane, 2007 Charlot, L., Deutsch, C., Hunt, A., Fletcher, K. and McIlvane, W. 2007. Validation of the Mood and Anxiety Semi-Structured (MASS) Interview for Patients with Intellectual Disabilities. Journal of Intellectual Disabilities Research, 51: 821–834. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Overall, few qualitative differences were detected between the 2 groups. Both depressed inpatient groups had high rates of comorbid anxiety disorders as well as externalizing behaviors. Inpatients with ASD had a total of 2 more symptoms (out of 29 possible symptom items) than their depressed peers without an ASD diagnosis (mean scores of 12.23 and 9.85, respectively). Anxiety disorders were reported in 62% of individuals with ASD and 38% of those without ASD. Antipsychotic medication was prevalent among the patients with ASD and depression. Over 80% of the inpatients with ASD and depression, compared with 49% of the non-ASD group, were treated with these medications.     

How is Anxiety Identified and Diagnosed in Individuals with Autism Spectrum Disorder and Intellectual Disability? A Scoping Review

ABSTRACT

Introduction: Individuals with Autism Spectrum Disorder display a pattern of social communication deficits and restricted and repetitive behaviors that leave them particularly vulnerable to developing anxiety. The presence of a co-occurring Intellectual Disability further complicates the situation, compromising traditional diagnostic techniques and processes. The dual diagnosis of ASD and ID appears to result in specific behavioral patterns that affect the way anxiety is identified in this population.

Method: A scoping review was undertaken to explore what is currently known about the way anxiety is identified and diagnosed in individuals with ASD and ID.

Results: In the limited research available consistent themes of difficulties with the diagnostic process, inconsistencies among measurement tools and the need to consider behavioral symptomology were found.

Conclusion: Further research needs to be conducted to enhance our understanding of how anxiety is identified in those with ASD and ID. This research could more accurately inform reliable diagnostic processes and lead to better treatment and outcomes for this population.     

Sleep Disturbances in Adults with Autism Spectrum Disorders and Severe Intellectual Impairments

Sleep disturbances are a significant problem for persons with developmental disabilities. These problems occur at a higher rate than what is observed in the typically developing population, and persons with Autism Spectrum Disorders (ASD) appear to be at a higher risk than individuals with other developmental disabilities. However, another major risk is intellectual disability (ID). These two groups of disorders overlap to a substantial degree. Thus, persons with ASD and ID appear to be particularly susceptible to sleep disturbances. These sleep problems can have serious consequences beyond sleep, particularly with respect to increased challenging behaviors and as an impediment to learning. Despite these concerns, adults with ASD and ID have been largely neglected with respect to the study of these nocturnal difficulties. In this report, 168 adults with ASD and ID were compared to 166 adults with ID alone in regard to sleep disturbance and related difficulties. Individuals in the ASD group presented with much higher rates of sleep disturbances, and greater severity of sleep disorder was related to the expression of more serious challenging behaviors. The implications of our results are discussed for future assessment and treatment of these disorders.     

Organizational and Unit Factors Contributing to Reduction in the Use of Seclusion and Restraint Procedures on an Acute Psychiatric Inpatient Unit

Objective The use of seclusion or restraint (S/R) as an emergency medical intervention to assist patients in regaining behavioral control continues to be an area of interest and concern for the Joint Commission on the Accreditation of Healthcare Organizations (JCAHO), consistent with the ongoing concerns in the medical, patient advocate, legislative and legal communities. This study examined unit characteristics and the use of S/R in a VA facility with a secured, acute mental health unit before and after the promulgation of the JCAHO 2000 standards for utilization of S/R for behavioral health reasons. Methods Variables examined include patient acuity, patient census, number of admits, number of discharges, length of stay, number of nursing staff on duty, critical incidents and S/R hours per month. Results Results indicated S/R use began showing a notable decrease corresponding to the time that senior unit management began discussions of the new JCAHO standards. These reductions maintained statistical significance even after controlling for changes in unit environmental variables.

“Driven and Tense,Stressed Out and Anxious”: Clinicians’ Perceptions of Post-Traumatic Stress Disorder Symptom Expressions in Adults with Autism and Intellectual Disability

ABSTRACT

Introduction

Individuals with autism spectrum disorder (ASD) and intellectual disability (ID) seem to be at increased risk for post-traumatic stress disorder (PTSD), but knowledge is sparse regarding its identification in this population. Previous research indicates that certain symptoms of PTSD may be more easily recognized, and that identifying reexperiencing and avoidance is particularly challenging.     

Profiles of Patients With Intellectual Disability and Mental Illness in Specialized and Generic Units in an Ontario Psychiatric Hospital

In a mental health system where limited specialized services exist for individuals with intellectual disability (ID), patients using such services should be those with the most complex needs. The purpose of this study was to compare the profile of patients with ID served in a specialized unit (n = 40) to those in generic units (n = 141) within one psychiatric teaching hospital in Ontario. Based on previous research, it was hypothesized that specialized patients would differ in terms of psychiatric diagnoses, service needs, overall level of functioning, and length of stay when compared with their counterparts in generic units. A retrospective review of select data from the Resident Assessment Instrument–Mental Health (RAI-MH) and Global Assessment of Functioning (GAF) was conducted for patients with ID discharged from all units of our hospital from 2006 to mid-2009. Though patients were demographically similar, those in the specialized unit stayed in the hospital longer than generic patients. Differences in psychiatric diagnoses, reasons for referral, overall functioning, and medication use were also found.     

Comparing Rates of Psychiatric and Behavior Disorders in Adolescents and Young Adults with Severe Intellectual Disability with and without Autism

Eight males and four females with an Autism Diagnostic Interview-Revised (ADI-R) diagnosis of autism (mean age of 16.3 years) and severe intellectual disability (IQ < 40) were individually matched to controls on the basis of chronological age, gender, and nonverbal IQ. The dependent measure was the Diagnostic Assessment for the Severely Handicapped-II, which is used to screen for psychiatric and behavior disorders in lower-functioning individuals. Participants with autism showed significantly greater disturbances as measured by the Diagnostic Assessment for the Severely Handicapped-II total score and seven of 13 subscales. They also averaged 5.25 clinically significant disturbances compared with 1.25 disturbances for participants without autism. Specific vulnerabilities to anxiety, mood, sleep, organic syndromes, and stereotypies/ tics were found in the participants with comorbid autism.     

Impact of Psychiatric Information on Potential Jurors in Evaluating High-Functioning Autism Spectrum Disorder (hfASD)

During a trial involving an offender with a mental disorder, jurors are often required to evaluate information on the disorder and its characteristics. This evaluation relies on how jurors understand and synthesize psychiatric and other evidence on the disorder and this information’s impact on the case, an offender’s culpability, and the rendered verdict. The importance of this evaluation is further highlighted when jurors are faced with evaluating a disorder that may be associated with criminal actions of diagnosed offenders, such as high-functioning autism spectrum disorder (hfASD). We designed a three-part survey to assess potential jurors’ attitudes concerning an offender’s diagnosis with hfASD in terms of perceptions and decisions surrounding legal and moral responsibility, personal characteristics of the offender, the introduction of psychiatric and genetic information, and the condition’s influence on the facts of the case. A sample of 623 jury-eligible U.S. adults completed the survey. We found the majority of participants were influenced by the information provided on hfASD. Most respondents indicated that hfASD diagnosis should generally not affect the legal responsibility of an offender, but many reported the disorder as a mitigating factor when evaluating moral responsibility and legal consequences for criminal actions. Respondents reported favorable and sympathetic perceptions of individuals with autism and associated characteristics but were unsure, even after the presentation of psychiatric information on hfASD, if these disorders should be classified as “mental illness.” Further, the majority reported their views were in some way influenced by the fact that hfASD has potential genetic origins.     

Comparing Observations and Perceptions of Mother-adolescent Conflict: Youth with Typical Development,Intellectual Disability,or Autism Spectrum Disorders

ABSTRACT

Introduction: While transitioning to adulthood presents challenges for youth with developmental disabilities (DD), opportunities to develop adult social roles and communication skills may foster more optimal outcomes. One such opportunity is developing conflict resolution skills within parent-adolescent relationships.

Methods: We examined how reported conflict and observed conflict resolution behaviors differed between adolescents with typical development or DD, specifically intellectual disability (ID) and/or autism spectrum disorder, and their mothers. Participants (n = 167) were mid-adolescents (age 15) from a longitudinal study of how psychopathology develops in youth with or without DD.

Results: While mothers’ Reported Conflict was similar across groups, Mother Problem Solving was highest, and Youth Problem Solving lowest, in families of youth with ID. Higher Reported Conflict related to more negative observed conflict resolution behaviors across all groups.

Conclusions: Results are considered in the context of transitioning to adulthood.
