Limitations
There are several limitations to this study. The high rate of cancellations and no-shows possibly resulted in a non-representative sample, particularly given socioeconomic barriers to attendance. The clinical nature of our program also created minor variance amongst test setting and screening measures. The lack of a control group for our sample precludes comparison to other children affected by chronic illness and/or socio-economic disadvantage. Also, the cross-sectional nature of this study limits the extent to which we can make causal inferences or definitive conclusions about trajectories, including the poorer performance seen in older age groups. In addition, because this screening was designed for brevity, additional information (e.g., in-depth measures of executive functioning, verbal learning, and visual-motor integration, and/or teacher report) related to was not obtained.
