Prevalence of psychoactive drug use among North Dakota group home residents.

To determine the prevalence of psychoactive medication usage among persons with mental retardation residing in community settings in the state of North Dakota, we sent a questionnaire to all group homes serving persons with developmental disabilities. The return rate was 97%. Psychoactive medications were used by 37% of residents represented. Results were discussed in relation to previous studies that have primarily involved institutionalized populations.
