BACKGROUND Reported prevalence of mental ill-health among adults with intellectual disabilities ranges from 7 to 97%, owing to methodological limitations. Little is known about associations. AIMS To determine the prevalence of mental ill-health in adults with intellectual disabilities and to investigate factors independently associated with it. METHOD(More)
BACKGROUND Self-injurious behaviour (SIB) is a serious condition, with implications for the person, their family and financial costs to the state providing care. The previously reported prevalence of SIB has ranged from 1.7% to 41%, or 1.7%-23.7% in community studies. There has been little study of remission rate, and incidence has not previously been(More)
OBJECTIVE To determine the point prevalence, incidence, and remission over a 2-year period of psychosis in adults with intellectual disabilities, and to investigate demographic and clinical factors hypothesised to be associated with psychosis. METHOD A population-based cohort of adults with intellectual disabilities (n = 1,023) was longitudinally studied.(More)
This study aimed to determine the prevalence of problem behaviors in adults with intellectual disabilities and to investigate which factors are independently associated with problem behaviors. A population-based cohort (n = 1023) had comprehensive individual assessments. Data were examined using multivariate logistic regression. The prevalence of problem(More)

BACKGROUND The point prevalence of mental ill-health among adults with intellectual disabilities is 40.9%, but its incidence is unknown. AIMS To determine the incidence and possible predictors of mental ill-health. METHOD Prospective cohort study to measure mental ill-health in adults with mild to profound intellectual disabilities. RESULTS Cohort(More)
INTRODUCTION Aggressive behaviours can be disabling for adults with intellectual disabilities (ID), with negative consequences for the adult, their family and paid carers. It is surprising how little research has been conducted into the epidemiology of these needs, given the impact they can have. This study investigates point prevalence, 2-year incidence(More)
BACKGROUND While there is considerable literature on adults with Down syndrome who have dementia, there is little published on the epidemiology of other types of mental ill-health in this population. METHOD Longitudinal cohort study of adults with Down syndrome who received detailed psychiatric assessment (n = 186 at the first time point; n = 134 at the(More)
BACKGROUND People with intellectual disabilities (IDs) have a higher level of health needs, a higher level of which is unmet, compared with the general population. Health screening can detect unmet health needs, but it is unknown whether it effects beneficial health outcomes in the longer term. People with IDs are reliant on health management by proxy and(More)
BACKGROUND Intellectual disabilities (ID) are common and lifelong. People with ID have health inequalities compared with the general population, but little is known about the epidemiology of affective disorders in this population. This study was undertaken to determine the point prevalence of affective disorders, and to investigate factors associated with(More)
