The purpose of this study was to examine the ability to predict outcomes of prescribed therapeutic recreation interventions (TRIs) for the treatment of the two major categories of disturbing behaviors in institutionalized older adults with dementia. Interventions were selected based on the participant's current level of functioning, past leisure interests, and the target behavior problem identified during baseline assessment. TRIs were then prescribed to calm individuals with agitated behaviors and (or) to alert individuals with passive behaviors. Each participant received two weeks of individually prescribed therapeutic recreation and biofeedback readings were randomly taken three times during the two-week intervention period to measure physiological change. The predicted outcome was found between 79-91% of the time when treating passivity, and between 92-100% of the time for agitation. Therapeutic recreation interventions were found to be predictable and efficacious for disturbing behaviors of dementia
