Individual plans for people with intellectual disabilities were evaluated for quality and effectiveness in improving quality of life. Quality was assessed by rating whether goals were relevant, observable, age appropriate, necessary, timetabled, developmental, measurable, realistic, assigned to staff and improving at least one of O'Brien's five service accomplishments [O'Brien & Tyne (1981) "The principle of normalization: a foundation for effective services." London, Campaign for the Mentally Handicapped]. Effectiveness was assessed by examining quality of life outcomes for participants with and without individual plans rated as higher quality. No significant difference in outcomes associated with having a higher quality individual plan was found. Findings present a challenge to current expectations that presence and quality of individual plan goals are associated with improved outcomes. Written individual plan goals may not be directly correlated with actual practice, and further research is required to examine this.
