Parents and children affected by pediatric cancer are at risk for psychological distress, including depression, anxiety, and post-traumatic stress. A link is believed to exist between parent and child distress; however, no systematic analysis of this relationship has occurred. A meta-analysis was conducted to assess the relationship between parent and child distress among families affected by pediatric cancer. A systematic review and meta-analysis was conducted using EBSCO (searching PsycINFO, MEDLINE, Academic search Premiere, and Health Source: Nursing/Academic Edition) and PubMed. The initial search yielded a total of 29,118 articles. Inclusion criteria were that studies assessed the relation between parent and child distress in the context of pediatric cancer, were written in English, and were published in peer-reviewed journals. 28 articles met inclusion criteria. A statistically significant association was found between overall parent and child distress (r = .32, p < .001), such that increased parent-reported distress was associated with increased distress in their children. Significant relationships were also present among each type of parental distress (i.e., depression, anxiety, post-traumatic stress, and global distress; rs = .31-.51, ps < .001) and overall child distress. Moderation analyses via meta-regression indicated that parent proxy-report of child symptoms was associated with a stronger relationship between parent and child distress than child self-report of their own distress. Aligned with the social-ecological framework, familial factors appear to be highly relevant in understanding distress following pediatric cancer diagnosis. Indeed, greater parent distress was associated with greater child distress.
