Quantifying the process and outcomes of person-centered planning

Although person-centered planning is a popular approach in the field of dev elopmental disabilities, there has been little systematic assessment of its process and outcomes. To measure person-centered planning, we developed th ree instruments designed to assess its various aspects. We then constructed variables comprising both a Process and an Outcome Index using a combined rational-empirical method. Test-retest reliability and measures of internal consistency appeared adequate. Variable correlations and factor analysis w ere generally consistent with our conceptualization and resulting item and variable classifications. Practical implications for intervention integrity , program evaluation, and organizational performance are discussed.
