The limited evidence on the relationship between problem behaviours and symptoms of psychiatric disorders experienced by adults with intellectual disabilities leads to conflict about diagnostic criteria and confused treatment. This study examined the relationship between problem behaviours and other psychopathology, and compared the predictive validity of dimensional and categorical models experienced by adults with intellectual disabilities. Exploratory and confirmatory factor analyses appropriate for non-continuous data were used to derive, and validate, symptom dimensions using two clinical datasets (n=457; n=274). Categorical diagnoses were derived using DC-LD. Severity and 5-year longitudinal outcome was measured using a battery of instruments. Five factors/dimensions were identified and confirmed. Problem behaviours were included in an emotion dysregulation-problem behaviour dimension that was distinct from the depressive, anxiety, organic and psychosis dimensions. The dimensi...

Associations between demographic and clinical variables and severe behavioural problems in people with intellectual disabilities were examined in a cross-sectional survey of 408 adults consecutively referred to a specialist mental health service. Severe behavioural problems were present in 136 (33.3%) of the sample. The demographic and clinical predictors of severe behavioural problems in this sample were identified by logistic regression. Age and gender were not associated with severe behavioural problems. The presence of severe ID independently predicted the presence of severe behavioural problems. Schizophrenia spectrum disorders and personality disorders independently predicted the presence of severe behavioural problems, whereas the presence of an anxiety disorder independently predicted their absence. There is an increasing evidence base of relationships between mental disorders and behavioural problems in people with ID although the pattern of these relationships remains unclear.
Incidence and predictors of mental ill-health in adults with intellectual disabilities
British Journal of Psychiatry, 2007
BackgroundThe point prevalence of mental ill-health among adults with intellectual disabilities is 40.9%, but its incidence is unknown.AimsTo determine the incidence and possible predictors of mental ill-health.MethodProspective cohort study to measure mental ill-health in adults with mild to profound intellectual disabilities.ResultsCohort retention was 70% (n=651). The 2-year incidence of mental ill-health was 16.3% (12.6% excluding problem behaviours, and 4.6% for problem behaviours) and the standardised incidence ratio was 1.87 (95%CI1.51 2.28). Factors related to incident mental ill-health have some similarities with those in the general population, but also important differences. Type of accommodation and support, previous mental ill-health, urinary incontinence, not having impaired mobility, more severe intellectual disabilities, adult abuse, parental divorce in childhood and preceding life events predicted incident ill-health; however, deprivation, other childhood abuse or a...
Psycho-Social Factors Influencing Mental Illness in Person with Intellectual Disability
Indian Journal of Natural Sciences, 2020
The prevalence rate of psychiatric disorders are 4 to 5 times higher for people with intellectual disability than the general population (Rush et al., 2004). Most of the persons affected by intellectual disabilities with mental illness go unnoticed with regard to their etiological condition. This study would expect to create an impact in providing awareness amongst the common public and professionals working in the field of rehabilitation to identify and to make possible efforts in preventing the potential factors attributing to such condition, which in turn will prevent a person with single disability becoming a person with multiple disabilites. By using the purposive sampling method parents of persons with intellectual disabilities were only incorporated for this study. The participants responses were collected by using Kuppuswamy SocioEconomic Status Scale (2014) and Reiss Screen for Maladaptive Behavior (2009) and the data were analysed with SPSS. The results of the study confirm the fact that psychosocial factors are influencing the psychotic features in persons with intellectual disabilities.
