Individual Habilitation Plan objectives for adults with mental retardation living in institutional or community settings were evaluated for effectiveness and quality. Effectiveness was assessed by contrasting change in relevant outcomes over time for participants with and without individual plan objectives in specified content areas. No significant change in outcomes associated with having an objective was detected for any of the content areas. Except for functionality, ratings of individual plans on all quality domains were poor. Regression analyses mostly failed to show any significant relationship between quality domain ratings and outcomes, although there was weak but inconsistent evidence for validity of the technical adequacy and data-collection quality domains. Findings present a challenge to current expectations that presence and quality of IHP objectives are associated with improved outcomes.
