In the print version of the article listed above, Figure 2 was inadvertently omitted and replaced by a duplicate of Figure 1B. The correct Figure 2 appears below. Also, a typographical error appeared in the text on p. 63. The sentence should have read, “We specifically focus on social support because of its importance for pediatric populations and its propensity to be changed through intervention, as opposed to other factors that may be more difficult to change.” The online version reflects these changes.
