Prevalence of, and factors associated with, problem behaviors in adults with intellectual disabilities.

Author information

NHS Greater Glasgow and Clyde, Glasgow, UK.


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 behaviors was 22.5% (psychiatrists' opinion) or 18.7% (DC-LD criteria). Factors independently associated with problem behaviors were lower ability level, female gender, living in a congregate care setting or with paid carer support (rather than living with a family carer), having urinary incontinence; visual impairment, not having Down syndrome, and not having severe physical disabilities. Further studies focusing on the etiology, course, and treatment of problem behaviors are required.
