A review of suicidality in persons with intellectual disability.
It has been assumed that impaired intellectual capacity could act as a buffer to suicidality in the population of persons with intellectual disability (ID), developmental disability or mental retardation. The few studies conducted contest this assumption and in fact findings show that the characteristics of suicidality in that population were very similar to that in persons without intellectual disability. This paper reviews the studies conducted and describes the symptomatology in this population, risk factors, screening and intervention. Professionals working with this population should therefore be aware of and assess for this behavior, since in one study it was found that many caregivers were unaware of suicidality in their clients. Only two studies had systematically examined differences between suicidal and non-suicidal individuals with ID with regard to risk factors. Risk factors found were history of prior psychiatric hospitalization, comorbid physical disabilities, loneliness, sadness, depression or anxiety. There is limited research on intervention for suicidal behavior in the ID population, but professionals should consider risk factors for suicide in this population and intervene when suicidal risk/behavior is found.
