Planned missing data designs allow researchers to have highly-powered studies by testing only a fraction of the traditional sample size. In two-method measurement planned missingness designs, researchers assess only part of the sample on a high-quality expensive measure, while the entire sample is given a more inexpensive, but biased measure. The…

We examined parents' satisfaction with multiple aspects of their children's individualized education programs (IEPs). Parents (n = 142) raising children ages 4 to 8 years old with autism spectrum disorder (ASD) reported their satisfaction with four aspects of their children's IEPs: (a) content of the IEP document, (b) services provided, (c)…

The purpose of this study is to investigate factors that may influence school administrators' disciplinary decisions involving students with disabilities. Confirmatory factor analysis suggests that the investigator-developed measures adequately represent the hypothesized latent factors per the pattern of observed responses. The hypothesized…

This article examines the impact of multiple individual and ecological factors on the self-determination of students with learning disabilities, mild and moderate mental retardation, and other health impairments. Baseline data from a multistate, longitudinal research project evaluating interventions to promote self-determination were examined…
