Método de Pesquisa

Based on an initial analysis of the abstracts or full texts of the 108 articles, we excluded 14 articles as being abstracts or book reviews. Thirty five were excluded because the authors did not focus on people with intellectual and developmental disabilities. We excluded an additional 35 studies that were exclu sively descriptive in nature. Of the remaining 24 potential articles, researchers in 9 examined only elements of the person-centered planning process (not effectiveness) and, therefore, were not includ ed. Only 15 studies met the two selection criteria referenced above. An overview summary of these 15 studies is presented in Table 1. This summary includes the study’s independent and dependent variables, sample size, design, data-collection strat egy, measurement instrument, and the main effects reported. As also shown in Table 1, 11 were quantitative and 4 were qualitative studies.
