Parents may maintain or exacerbate functional abdominal pain (FAP) in children through modeling of physical symptoms and solicitous responses to the child's complaints. This systematic review and meta-analysis aimed to examine these relationships. Parents of children with FAP reported more physical symptoms than parents of healthy children (effect size d = .36). As all studies were cross-sectional or retrospective, the causal direction was unclear. For parental responses to child complaints, not enough studies were available to perform a meta-analysis. We conclude that the present literature is unfit to establish whether parents maintain or exacerbate pediatric FAP through the processes investigated.
