Psychiatric and psychosocial problems in adults with normal-intelligence autism spectrum disorders
BMC Psychiatry, 2009
Background: Individuals with autism spectrum disorders (ASDs) often display symptoms from other diagnostic categories. Studies of clinical and psychosocial outcome in adult patients with ASDs without concomitant intellectual disability are few. The objective of this paper is to describe the clinical psychiatric presentation and important outcome measures of a large group of normalintelligence adult patients with ASDs.
Psychopathology in Adults with Autism and Intellectual Disability
Journal of Autism and Developmental Disorders, 2006
There have been few studies of psychopathology in adult with autism. This study examined psychiatric co-morbidity in 147 adults with intellectual disability (ID) and autism and 605 adults with ID but without autism. After controlling for the effects of gender, age, psychotropic medication and level of ID, people with autism and ID were no more likely to receive a psychiatric diagnosis than people with ID only. People with autism were less likely to receive a diagnosis of personality disorder. These findings cast doubts on the hypothesis that adults with ID and autism are more vulnerable to certain psychiatric disorders than non-autistic adults with ID.
Mental health of adults with autism spectrum disorders and intellectual disability
Current opinion in psychiatry, 2010
Purpose of review The literature has often suggested that individuals with intellectual disability who have an autism spectrum disorder (ASD) experience higher rates of mental health problems than those without ASD. This finding has been challenged in recent years and so the purpose of this article was to critically review relevant studies since March 2009. The review focuses on studies specifically about the mental health of adults with intellectual disability who have ASD. Recent findings Recent studies do not support the hypothesis that adults with intellectual disability and ASD are more vulnerable to psychiatric disorders than those without ASD. Factors found to be associated with poorer mental health include severity of intellectual disability, adaptive behaviour skills and social skills. Summary The evidence base on the mental health of adults with intellectual disability and ASD is small but rapidly increasing. Studies tend to have relatively small sample sizes and there remain difficulties in accurately assessing ASD and psychopathology in adults with intellectual disability.
The relationship between autism and psychiatric disorders in Intellectually Disabled Adults
Research in Autism Spectrum Disorders, 2007
Intellectual Disability (ID) shows a high comorbidity with psychiatric disorders with a great variability in the prevalence rates. An important subgroup is represented by subjects with ID and autism or other autistic spectrum disorders (PDD). The purpose of the present study was to assess PDD with specific screening tools in a population of people with ID and compare the groups with or without PDD through the administration of a psychopathological scale in order to verify the differences of psychiatric disorders' rates. The study was conducted on 90 subjects attending daily centres or residential centres in Florence, Italy. In order to assess the presence of PDD, the PDD-MRS was administrated, while for the assessment of the psychopathological aspects we have used the DASH-II. The presence of a psychiatric disorder has a significant effect on anxiety, depression and organic syndromes and statistically significant differences have been registered in many DASH-II subscales. The statistical comparison between the two groups shows that PDD was clearly correlated with an increased presence of psychiatric disorders. The variable PDD could be considered as a vulnerability factor for psychiatric disorders. However there was still the need to focus on categorical diagnoses, in order to increase our knowledge about the concept of vulnerability in people with ID.

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.

Autism spectrum disorders (ASD) are characterized by deficits in three areas of functioning: communication, socialization, and restricted interests/repetitive behavior. With the rise in diagnoses of ASD in recent years, these disorders have received increasing recognition by researchers and clinicians. These efforts have largely been with young children. However, the study of ASD and comorbid disorders in adults with intellectual disability (ID) has been almost nonexistent. While there are measures available to assess comorbid disorders in people with only ID, the differences in adults with ASD and ID and adults with ID alone may also be a good deal different than in children, and therefore warrants a specialized scale to measure symptoms of ASD in this population. Through research, it is recognized that persons with ASD and ID often evince concomitant psychopathology; yet, the topic has not been systematically studied. The Autism Spectrum Disorders-Comorbidity for Adults (ASD-CA) was designed to screen symptoms of psychopathology that occur more commonly with ASD/ID in adults. The objective of this study was to assess the reliability of the ASD-CA in a first attempt to establish the test's psychometric properties. Three forms of reliability (inter-rater, test-retest, and internal consistency), item analysis, and a factor analysis were conducted.
The validity of the autism spectrum disorders-diagnosis for intellectually disabled adults (ASD-DA
Research in Developmental Disabilities, 2008
Psychologists interviewed direct-care staff using a battery of assessment measures including the autism spectrum disorders-diagnosis for intellectually disabled adults (ASD-DA), the Diagnostic Assessment for the Severely Handicapped-II (DASH-II), the Matson Evaluation of Social Skills for Individuals with Severe Retardation (MESSIER), the Socialization domain of the Vineland Adaptive Behavior Scales (VABS), and a checklist containing criteria for autism and PDD-NOS from the DSM-IV-TR and ICD-10. Three hundred and seven intellectually disabled (ID) adolescents and adults ranging in age from 16 to 88 were assessed. Participants were diagnosed with either ID and ASD (autism or PDD-NOS; n = 156) or ID and no Axis I diagnosis (n = 151). A modification of the multitrait-multimethod approach was used to establish the convergent and discriminant validity of the ASD-DA. The scale proved to have robust convergent validity when correlated with the DSM-IV-TR/ICD-10 checklist, MESSIER, and Socialization domain of the VABS. Additionally, discriminant validity was demonstrated by comparing the ASD-DA to items from the DASH-II (measure of general psychopathology). The implications of these data are discussed. #

The prevalence, and incidence, of mental ill-health in adults with intellectual disabilities and autism were compared with the whole population with intellectual disabilities, and with controls, matched individually for age, gender, ability-level, and Down syndrome. Although the adults with autism had a higher point prevalence of problem behaviours compared with the whole adult population with intellectual disabilities, compared with individually matched controls there was no difference in prevalence, or incidence of either problem behaviours or other mental ill-health. Adults with autism who had problem behaviours were less likely to recover over a two-year period than were their matched controls. Apparent differences in rates of mental ill-health are accounted for by factors other than autism, including Down syndrome and ability level.
Health and Social Functioning of Adults With Intellectual Disability and Autism
Journal of Policy and Practice in Intellectual Disabilities , 2013
There is little information on the mental health needs of adultswith intellectual disability (ID) and autism spectrum disorders (ASDs). Such evidence is much needed for the development of more effective mental health services for this group. The aim of this study is to compare adults with ID and ASD receiving specialist mental health services with participants without ASD. Data were collected from the anonymized case records of a clinic-based population in South East London. Health and social functioning were measured using the Health of the Nation Outcome Scale for people with Learning Disability (HoNOS-LD). A review of case records identified 371 service users in receipt of specialist mental health care who were eligible for the study. There were 117 people (32% of the sample) with a clinical diagnosis of ID and ASD. Participants with ASD were younger, more likely to be male, less likely to live independently and had more severe ID than those without ASD. Furthermore, those with ID and ASD were less likely to be diagnosed with a psychiatric disorder but had significantly higher scores on the HoNOS-LD (indicating lower health and social functioning) than those without ASD. A significant proportion of adults with ID who are in receipt of specialist mental health services also have a clinical diagnosis of ASD. This group has different mental health needs compared with those without ASD. The authors note the need for a more personalized approach to service delivery with a focus on improving social functioning and behavioral impairments.
