Incontinence in children, adolescents and adults with Williams syndrome.

Williams Syndrome (WS) is a microdeletion syndrome (chromosome 7q11.23) characterized by typical facial features, cardiovascular disease, behavioural symptoms, and mild intellectual disability (ID). The aim of this study was to assess the rates of incontinence and psychological problems in persons with WS. 231 individuals with WS were recruited through the German parent support group (52.0% male, mean age 19.4 years). Faecal incontinence (FI) was diagnosed from the age of 4 years and nocturnal enuresis (NE) and daytime urinary incontinence (DUI) of 5 years onwards. The Parental Questionnaire: Enuresis/Urinary Incontinence, the International-Consultation-on-Incontinence-Questionnaire-Pediatric LUTS (ICIQ-CLUTS), as well as the Developmental Behavior Checklist for parents (DBC-P) or for adults (DBC-A) were filled out by parents or caregivers. 17.8% of the sample had NE, 5.9% DUI and 7.6% FI. NE was present in 44.9% of children (4-12 years), 13.5% of teens (13-17y), 3.3% of young adults (18-30y) and in 3.6% of adults (> 30y). DUI (and FI) decreased from 17.9% (21.4%) in children to 0% in adults. 3.5% of the sample had an ICIQ-CLUTS score in the clinical range. 30.5% of children and 22.1% of adults had a clinical DBC score. Children and teens with clinically relevant DBC-P-scores had significantly higher DUI rates. Children with WS have high rates of incontinence and LUTS, which decrease with age. Most adults are continent. NE is the most common subtype. Except for DUI in children, incontinence is not associated with behavioural problems. Screening, assessment and treatment of incontinence in individuals with WS is recommended. Neurourol. Urodynam. 35:1000-1005, 2016. © 2015 Wiley Periodicals, Inc.

Incontinence in persons with Noonan Syndrome

Noonan Syndrome (NS) is an autosomal neurodevelopmental disorder with a high phenotypic variability. Mutations in several genes of the RASMAPK signaling pathways are now known to be responsible for NS. Most of the children with NS are of average intelligence, one-third have a mild intellectual disability (ID) (IQ 50-79). So far, no studies have assessed incontinence in persons with NS. The aim of this study therefore was to investigate the prevalence of incontinence and psychological problems in persons with NS. Nineteen children (5-17 years) and 10 adults (18-48 years) with NS were recruited through a German parent support group (58.6% male, mean age 15.26 years). The "Parental Questionnaire: Enuresis/Urinary Incontinence", "Encopresis Questionnaire - Screening Version" and the German version of the International Consultation on Incontinence Questionnaire - Pediatric Lower Urinary Tract Symptom (ICIQ-CLUTS) were completed by parents or caregivers to assess incontinence and lower urinary tract symptoms (LUTS). The Developmental Behavior Checklist for parents (DBC-P) or the Developmental Behavior Checklist for adults (DBC-A) were filled out to assess psychological symptoms. In total, 27.3% of the children (4-12 years) had nocturnal enuresis (NE), 36.4% had daytime urinary incontinence (DUI), and 11.1% had fecal incontinence (FI). Only one adolescent (13-17 years) had NE (14.3%) and one young adult (18-30 years) had FI (11.1%); 36.4% of the children, 33.3% of the adolescents and 12.5% of young adults had a DBC score in the clinical range. No adult (>30 years) had incontinence or a critical DBC score. Children and adolescents with NE had significantly higher scores in the DBC total score as well in the "self-absorbed" and "social relating" subscales than continent children and adolescents, whereas no significant difference was found between children and adolescents with DUI compared with the continent group. A significant proportion of children with NS are affected by incontinence. Incontinence is a relevant problem in children and adolescents with NS, but does not persist into adulthood. In particular, psychological problems are present in children and adolescents with NE. Screening for both incontinence and psychological symptoms are recommended in children with NS. As most of the children with NS have average intelligence or a mild ID, they can be treated effectively with standard methods.

Emotional and behavioural problems in young children with autism spectrum disorder.

To assess the frequency, pervasiveness, associated features, and persistence of emotional and behavioural problems in a community sample of young children with autism spectrum disorder (ASD). Parents (n=277) and teachers (n=228) of 4- to 8-year-olds completed the Developmental Behaviour Checklist (DBC). Intellectual ability and autism symptomatology were also assessed. A subsample repeated the DBC. Three-quarters of the cohort scored above the clinical cut-off on the Developmental Behaviour Checklist Primary Carer Version (DBC-P) questionnaire; almost two-thirds of these scored above cut-off on the Developmental Behaviour Checklist Teacher Version (DBC-T) questionnaire. In 81%, problems persisted above threshold 14 months later. Higher DBC-P scores were associated with greater autism symptomatology, higher deprivation index, parental unemployment, and more children in the home but not with parental education or ethnicity, or child's age or sex. Children with IQ>70 scored higher for disruptive behaviour, depression, and anxiety symptoms; those with IQ<70 scored higher for self-absorption and hyperactivity. The DBC identifies a range of additional behaviour problems that are common in ASD and which could be the focus for specific intervention. The results highlight the potential benefit of systematic screening for co-existing problems.

Central nervous system medication use in older adults with intellectual disability: Results from the successful ageing in intellectual disability study.

Information on the rates and predictors of polypharmacy of central nervous system medication in older people with intellectual disability is limited, despite the increased life expectancy of this group. This study examined central nervous system medication use in an older sample of people with intellectual disability. Data regarding demographics, psychiatric diagnoses and current medications were collected as part of a larger survey completed by carers of people with intellectual disability over the age of 40 years. Recruitment occurred predominantly via disability services across different urban and rural locations in New South Wales and Victoria. Medications were coded according to the Monthly Index of Medical Specialties central nervous system medication categories, including sedatives/hypnotics, anti-anxiety agents, antipsychotics, antidepressants, central nervous system stimulants, movement disorder medications and anticonvulsants. The Developmental Behaviour Checklist for Adults was used to assess behaviour. Data were available for 114 people with intellectual disability. In all, 62.3% of the sample was prescribed a central nervous system medication, with 47.4% taking more than one. Of those who were medicated, 46.5% had a neurological diagnosis (a seizure disorder or Parkinson's disease) and 45.1% had a psychiatric diagnosis (an affective or psychotic disorder). Linear regression revealed that polypharmacy was predicted by the presence of neurological and psychiatric diagnosis, higher Developmental Behaviour Checklist for Adults scores and male gender. This study is the first to focus on central nervous system medication in an older sample with intellectual disability. The findings are in line with the wider literature in younger people, showing a high degree of prescription and polypharmacy. Within the sample, there seems to be adequate rationale for central nervous system medication prescription. Although these data do not indicate non-adherence to guidelines for prescribing in intellectual disability, the high rate of polypharmacy and its relationship to Developmental Behaviour Checklist for Adults scores reiterate the importance of continued medication review in older people with intellectual disability.

The developmental trajectory of disruptive behavior in Down syndrome, fragile X syndrome, Prader-Willi syndrome and Williams syndrome.

The aim of this study was to investigate the developmental trajectories of verbal aggression, physical aggression, and temper tantrums in four genetic syndrome groups. Participants were part of the Australian Child to Adult Development Study (ACAD), which collected information from a cohort of individuals with an intellectual disability at five time points over 18 years. Data were examined from a total of 248 people with one of the four following syndromes: Down syndrome, Fragile X syndrome, Prader-Willi syndrome, or Williams syndrome. Changes in behaviors were measured using validated items from the Developmental Behavior Checklist (DBC). The results indicate that, while verbal aggression shows no evidence of diminishing with age, physical aggression, and temper tantrums decline with age before 19 years for people with Down syndrome, Fragile X syndrome, and William syndrome; and after 19 years for people with Prader-Willi syndrome. These findings offer a somewhat more optimistic outlook for people with an intellectual disability than has previously been suggested. Research is needed to investigate the mechanisms predisposing people with PWS to persistence of temper tantrums and physical aggression into adulthood.

Depressive and Anxiety Symptom Trajectories From School Age Through Young Adulthood in Samples With Autism Spectrum Disorder and Developmental Delay

The objectives of this study were to model growth in anxiety and depressive symptoms from late school age through young adulthood in individuals with autism spectrum disorder (ASD) and controls with developmental delay (DD), and to assess relationships among internalizing growth patterns, participant characteristics, baseline predictors, and distal outcomes. Data were collected between ages 6 and 24 years in 165 participants (n = 109 with ASD; n = 56 with nonspectrum DD), most of whom received diagnostic evaluations in both childhood and early adulthood. Questionnaires were collected approximately every 3 to 6 months between ages 9 and 24 years. Parent-rated Child Behavior Checklist (CBCL), Adult Behavior Checklist (ABCL), and Developmental Behaviour Checklist anxiety- and depression-related subscale distributions were modeled with mixed-effects Poisson models, covarying diagnosis, age, verbal IQ (VIQ), gender, and significant 2- and 3-way interactions. Anxiety was positively associated with VIQ, and controlling for VIQ, both anxiety and depressive symptoms were greater in ASD than nonspectrum participants. Female gender predicted greater increases over time in anxiety and depressive symptoms for both diagnostic groups. Lower maternal education was associated with increasing internalizing symptoms in a subset of less verbal individuals with ASD. In exploratory post hoc analyses, internalizing symptoms were associated with poorer emotional regulation in school age, and with lower life satisfaction and greater social difficulties in early adulthood. Findings support previous claims that individuals with ASD are at particular risk for affect- and anxiety-specific problems. Although symptom levels in females increase at a faster rate throughout adolescence, males with ASD appear to have elevated levels of depressive symptoms in school age that are maintained into young adulthood.

Behavior in children with Prader-Willi syndrome before and during growth hormone treatment: a randomized controlled trial and 8-year longitudinal study.

Information on behavior of children with Prader-Willi syndrome (PWS) and the effect of growth hormone (GH) treatment is scarce. Parents report less problem behavior during GH treatment. Forty-two pre-pubertal children, aged 3.5-14years were studied in a randomized controlled GH trial (RCT) during 2 years, followed by a longitudinal study during 8 years of GH treatment. Behavior was measured annually by the Developmental Behavior Checklist for children with intellectual disability (DBC) and a Dutch questionnaire to evaluate social behavioral problems in children, the Children's Social Behavior Questionnaire (CSBQ). Problem behavior measured by the DBC in children with PWS was similar compared to peers with comparable intellectual disability. Scores on 'Social disabilities' subscale were however significantly higher compared to the DBC total score (p<0.01). A lower IQ was associated with more self-absorbed behavior, more communication problems and more problem behavior in general. Problem behavior measured by the CSBQ was similar compared to peers with a comparable intellectual disability, but children with PWS scored significantly higher on the 'Not tuned', 'Understanding', and 'Stereotyped' subscales than the CSBQ total score (p<0.05 for all subscales and p=0.001 for the 'Not tuned'-subscale). There were no significant effects of GH treatment during the RCT and 8years of GH treatment. Children with PWS showed similar problem behavior as a reference population with a comparable intellectual disability. Social problems were the most pronounced within-problem behavior in PWS. In contrast to our expectations and parents reports, our study shows no improvement but also no deterioration of behavioral problems in children with PWS during long-term GH treatment.

Do non-referred young people with Autism Spectrum Disorders and their caregivers agree when reporting anxiety symptoms? A preliminary investigation using the Spence Children's Anxiety Scale

Anxiety difficulties and disorders are common in children and youth people with Autism Spectrum Disorders (ASD), but only a few studies have specifically examined informant agreement in non-referred samples. The present study examined informant agreement between 38 Singaporean caregiver–child dyads using the Spence Children's Anxiety Scale Parent Version (SCAS-P) and the SCAS Child self-report (SCAS-C) respectively. The young people with ASD (mean age 12 years 10 months) completed the SCAS-C, while their caregivers completed the SCAS-P, the Scales of Independent Behavior-Revised and the Developmental Behavior Checklist. There was overall moderately good agreement between caregivers and children's reporting of anxiety symptoms. Intra-class correlations were highest in the Separation Anxiety, Generalized Anxiety and Physical Injury subscales. Fourteen of the 38 SCAS items, most of which described overt anxiety symptoms, showed strong or moderate inter-rater agreement. Higher severity of autism symptoms was associated with poorer agreement in the Generalized Anxiety, Panic and Obsessions/Compulsions SCAS subscales. These preliminary findings suggest that the SCAS may be a useful measure for reporting anxiety symptoms in terms of satisfactory agreement between caregivers and young people in non-referred settings. Implications for screening for anxiety in non-referred young people with ASD are also discussed.

Psychometric properties and normative data of the French Developmental Behavior Checklist – Adult version

The main aim of this study was to generate psychometric data for the French translation of the Developmental Behavior Checklist - Adult version (DBC-A). In addition, the score distributions were examined by using components of mean-based scores. The DBC-A was administered to 580 adults with intellectual disability recruited in the French-speaking regions of Switzerland and Belgium. A confirmatory factor analysis was performed to evaluate the adjustment of the collected data to the original six-factor model; the internal consistency of the factors was analyzed with Cronbach's alpha. The Reiss Screen for Maladaptive Behavior was used to evaluate the concurrent validity of the instrument. Psychopathology prevalence was also explored. The original factor structure of the DBC-A was replicated, with the internal consistency of the factors ranging from respectable to very good according to the alpha values. When the "screening" cut-off of the DBC-A was used, the DBC-A highlighted a psychopathology prevalence of 38%, which was close to the frequency provided by the Reiss Screen (36%). These results show the robustness of the DBC-A's psychometric properties. Thus, we recommend the use of this instrument to assess and screen psychopathology among French-speaking adults with intellectual disability.

EPA-0297 – Predictors of challenging behaviour among mental health service users with intellectual disability and autism spectrum disorders

Introduction Autism spectrum disorder (ASD) affects 20–30% of adults with intellectual disability. This group are vulnerable to challenging behaviour and mental health problems. Objectives To explore the extent to which ASD affects challenging behaviour among specialist mental health service users with intellectual disability. Aims To identify predictors of challenging behaviour among adults who have intellectual disability. Methods A cross-sectional study of 92 participants from a specialist mental health service for adults with intellectual disability in the UK. The presence/absence of ASD was confirmed using the Autism Diagnostic Observation Schedule. Challenging behaviour was assessed using the Developmental Behaviour Checklist (DBC). Results Participants with ASD (N=48) had higher total DBC scores than those without ASD (N=44; mean=54.2 vs. 29.2). ASD, severity of intellectual disability, age, presence of psychiatric disorder and total number of needs were entered as independent variables into a linear regression. The model accounted for 51% of the variance and was statistically significant (F(5,91)=18.1, p Conclusion Participants with ASD had significantly higher levels of challenging behaviour than those without ASD. Challenging behaviour was also independently associated with total number of needs. Understanding which service users with intellectual disability have higher levels of challenging behaviour than others despite receiving psychiatric treatment, and the extent to which having ASD is a contributing factor, should inform the development of more effective services and lead to improved outcomes.

Adaptive Behavior and Problem Behavior in Young Children With Williams Syndrome

The present study compares the adaptive behavior profile of 18 young children with Williams syndrome (WS) and a developmentally matched group of 19 children with developmental disabilities and examines the relationship between adaptive behavior and problem behaviors in WS. Parents completed the Vineland Adaptive Behavioral Scales-Interview edition and the Developmental Behavior Checklist-Primary Caregiver version (WS only). Children with WS had higher adaptive communication scores than children with other developmental disabilities. Children with WS demonstrated relative strengths in adaptive communication and socialization, coupled with relative weaknesses in daily living. Adaptive communication and socialization were negatively associated with problem behaviors in social relating in WS.

Psychotropic medication use in adolescents with intellectual disability living in the community

Information on the use of psychotropic medications in adolescents with intellectual disability is scant. Such information can guide interventions to improve psychotropic medication use in this population. We investigated the prevalence of, and factors associated with, psychotropic medication use in adolescents with intellectual disability in Australia who live in the community. Cross-sectional data were obtained from adolescents with intellectual disability living in the community in South East Queensland, Australia, between February 2007 and September 2010. Self-reported information on medication use was extracted from a health screening tool. Demographic and medical data were collected through parent/caregiver surveys. Medications were classified according to the Anatomical Therapeutic Chemical classification system. Psychopathology was assessed using the Developmental Behaviour Checklist Short Form. Logistic regression analysis was used to assess the association of demographic and medical characteristics with psychotropic medication use. There were 176 participants (median age = 16 years, range = 11-19 years; 55% male). Psychotropics were used by 20% of participants. Psychostimulants were the commonest psychotropic class, used by 9% of participants. Multipsychotropic prescribing was not common with only seven participants using more than one psychotropic agent. After adjusting for potentially confounding variables, use of psychotropic medications was significantly associated with male gender (adjusted odds ratio = 3.6; 95% confidence interval = 1.3-9.5) and having major behaviour problems (3.1; 1.1-8.9). Adolescents with intellectual disability use a wide range of psychotropic medications. Being male and having major behaviour problems are associated with the use of psychotropic medications. Research examining the rationale for psychotropic prescribing in this population is needed.

Behavioral profile of adults with Prader-Willi syndrome: correlations with individual and environmental variables

BackgroundMaladaptive behavior has been reported as a phenotypical feature in Prader–Willi syndrome (PWS). It severely limits social adaptation and the quality of life of children and adults with the syndrome. Different factors have been linked with the intensity and form of these behavioral disturbances but there is no consensus about the cause. Consequently, there is still controversy regarding management strategies and there is a need for new data.MethodsThe behavior of 100 adults with PWS attending a dedicated center was assessed using the Developmental Behavior Checklist for Adults (DBC-A) and the PWS-specific Hyperphagia Questionnaire. The DBC-A was completed separately by trained caregivers at the center and relatives or caregivers in a natural setting. Genotype, gender, age, degree of obesity and cognitive impairment were analyzed as variables with a hypothetical influence on behavioral features.ResultsPatients showed a relatively high rate of behavioral disturbances other than hyperphagia. Disruptive and social relating were the highest scoring DBC-A subscales whereas anxiety/antisocial and self-absorbed were the lowest. When hospital caregiver and natural caregiver scores were compared, scores for the latter were higher for all subscales except for disruptive and anxiety/antisocial. These effects of institutional management were underlined. In the DBC-A, 22 items have descriptive indications of PWS behavior and were used for further comparisons and correlation analysis. In contrast to previous reports, rates of disturbed behavior were lower in patients with a deletion genotype. However, the behavioral profile was similar for both genotypes. No differences were found in any measurement when comparing type I and type II deletions. The other analyzed variables showed little relevance.ConclusionsSignificant rates of behavioral disorders were highlighted and their typology described in a large cohort of adults with PWS. The deletion genotype was related to a lower severity of symptoms. Some major behavioral problems, such as hyperphagia, may be well controlled if living circumstances are adapted to the specific requirements of individuals with PWS.

Intellectual Disability and Mental Ill Health: A View of Australian Research

This general review situates Australian research within a framework that quantifies and describes mental health needs of the population with intellectual disabilities across the life span, surveys service provision, and develops the evidence base to inform clinicians regarding assessment and management of psychopathology and psychiatric disorder in people with intellectual disabilities. In particular, Australian research has examined the prevalence, nature, associated factors, and trajectory of clinically significant psychopathology from childhood to adulthood. The Developmental Behavior Checklist and a suite of versions, including an adult version, have proven to be robust instruments in identifying and describing psychopathology in people with intellectual disabilities. Australian researchers have also examined aspects of psychiatric assessment in a population with cognitive and communication impairments, which has direct relevance to clinical practice. Surveys and audits of policy, real-life practice, and service structure and provision have identified serious deficiencies in the training of health professionals and the provision of mental health care to people of all ages with intellectual disabilities and mental ill health. In light of the weight of the evidence, state and federal governments are developing new service models and there are increasing opportunities for professional education and training.

Behavioral phenotype in five individuals with de novo mutations within the GRIN2B gene

BackgroundIntellectual disability (ID) is often associated with behavioral problems or disorders. Mutations in the GRIN2B gene (MRD6, MIM613970) have been identified as a common cause of ID (prevalence of 0.5 – 1% in individuals with ID) associated with EEG and behavioral problems.MethodsWe assessed five GRIN2B mutation carriers aged between 3 and 14 years clinically and via standardized questionnaires to delineate a detailed behavioral phenotype. Parents and teachers rated problem behavior of their affected children by completing the Developmental Behavior Checklist (DBC) and the Conners’ Rating Scales Revised (CRS-R:L).ResultsAll individuals had mild to severe ID and needed guidance in daily routine. They showed characteristic behavior problems with prominent hyperactivity, impulsivity, distractibility and a short attention span. Stereotypies, sleeping problems and a friendly but boundless social behavior were commonly reported.ConclusionOur observations provide an initial delineation of the behavioral phenotype of GRIN2B mutation carriers.

Verhaltenssymptome bei Kindern im Vorschul- und Schulalter mit Prader-Willi-Syndrom – eine explorative Studie zu ritualisierten Verhaltensformen

Parents of 64 children and youths with Prader-Willi syndrome (PWS) describe their children's behaviour on the "Temperament and Atypical Behavior Scale" (TABS) and the German version of the "Developmental Behavior Checklist" (VFE). In the younger age group, there are no specific behavioural abnormalities which characterize a behavioral phenotype. In the older age group the data reveal elevated levels of abnormal behaviors (communication disturbance, social relations and disruptive behaviors). Parents stress ritualistic behaviors as especially challenging. The results concerning form and age-dependency of abnormal behaviors are discussed in the context of prevention and treatment options.

Brief Report: The Relationship Between Language Skills, Adaptive Behavior, and Emotional and Behavior Problems in Pre-schoolers with Autism

This study investigated the relationship between structural language skills, and communication skills, adaptive behavior, and emotional and behavior problems in pre-school children with autism. Participants were aged 3-5 years with autism (n = 27), and two comparison groups of children with developmental delay without autism (n = 12) and typically developing children (n = 20). The participants were administered standardised tests of structural language skills, and parents completed the Vineland Adaptive Behavior Scales and the Developmental Behaviour Checklist. Results indicated that for children with autism, communication skills, and in particular receptive communication skills, were associated with social and daily living skills, and behavior problems. Receptive structural language skills were associated with expressive communication skills. There were no associations found between structural language skills and social or daily living skills, nor behavior problems. The results of this study suggest that communication skills are more closely linked to functional and behavioral outcomes in autism than structural language skills.

Behavioral problems in children with motor and intellectual disabilities: Prevalence and associations with maladaptive personality and marital relationship

Prevalence rates of behavioral problems in children with motor disabilities are commonly based on questionnaires developed for a general population (e.g., Child Behavior CheckList). These questionnaires do not take into account lower levels of intellectual functioning. The first aim of this study was to examine the prevalence of parent-reported and daily caretaker-reported behavioral problems in children with motor and intellectual disabilities (MID) using the Developmental Behavior Checklist. Second, we investigated whether behavioral problems were related to sex and age. Our third and fourth aim were to determine whether behavioral problems are related to maladaptive personality traits and to marital stress and conflict. Participants were 101 Flemish children with MID (mean age=14 years 6 months). For total behavioral problems, we found prevalence rates of 18% and 8% based on parent and daily caretaker reports, respectively. Based on parent reports, twenty seven percent of the children with MID exhibited anxiety problems. Behavioral problems were not related to sex. Older children showed fewer behavioral problems than younger children. Multiple hierarchical regression analyses revealed that lower scores on Compulsivity and higher scores on Emotional Instability and Disagreeableness were related to behavioral problems. In addition to personality traits, stress and conflict in the marital relationship was also positively associated with behavioral problems. Given the importance of behavioral problems in children with MID, this study is of theoretical and clinical interest and has the potential to inform targeted clinical interventions.

The behavioral phenotype of Mowat–Wilson syndrome

Mowat-Wilson syndrome (MWS) is caused by a heterozygous mutation or deletion of the ZEB2 gene. It is characterized by a distinctive facial appearance in association with intellectual disability (ID) and variable other features including agenesis of the corpus callosum, seizures, congenital heart defects, microcephaly, short stature, hypotonia, and Hirschsprung disease. The current study investigated the behavioral phenotype of MWS. Parents and carers of 61 individuals with MWS completed the Developmental Behavior Checklist. Data were compared with those for individuals selected from an epidemiological sample of people with ID from other causes. The behaviors associated with MWS included a high rate of oral behaviors, an increased rate of repetitive behaviors, and an under-reaction to pain. Other aspects of the MWS behavioral phenotype are suggestive of a happy affect and sociable demeanor. Despite this, those with MWS displayed similarly high levels of behavioral problems as those with intellectual disabilities from other causes, with over 30% showing clinically significant levels of behavioral or emotional disturbance. These findings have the potential to expand our knowledge of the role of the ZEB2 gene during neurodevelopment. Furthermore, they are a foundation for informing interventions and management options to enhance the independence and quality of life for persons with MWS.

Mental Health Needs in Adolescents with Intellectual Disabilities: Cross‐Sectional Survey of a Service Sample

Little research has been conducted on the mental health needs of adolescents with intellectual disability, despite the severity and rates of such needs being high throughout childhood and in adulthood. We have investigated the prevalence and predictors of mental health needs and service use in adolescents with intellectual disabilities. Service-based sample (n = 75) in one catchment area. Individual assessments were carried out. The main outcome was the presence of mental health needs measured by the Developmental Behaviour Checklist. Prevalence of mental health needs increased from 51% as reported by parents to 67% as judged by clinical interviews. Caseness was associated with low adaptive functioning, diagnosis of autism and family history of mental illness. High scores on parent reports of participant mental ill-health showed negative correlations with adaptive functioning scores. Most individuals were in receipt of social and health care. Half of the participants had sought help for mental health needs. Almost half of those receiving medication were on psychiatric medication. Adolescents with intellectual disabilities may have considerable mental health problems which are functionally impairing yet frequently unidentified and hence untreated. Identification of those at risk and undertaking of a comprehensive needs assessment are essential to maximize potential and quality of life and to reduce further deficits and social exclusion.
