Between-group analyses will address how these multiple variables differ for the chest pain group and patients presenting for an evaluation for heart murmurs. This will be true at both the time of the patients' appointment and at follow-up. Further, within-group correlational analyses will be conducted primarily for with the chest pain group. The goal of these within group analyses will be to address how the various child, parent, and familial factors correlate with the children's chest pain symptoms, healthcare utilization, other somatic symptoms, and functional disability. In addition, for the chest pain group, the patients' and their families' functioning at the time of the initial appointment will be used to predict chest pain and other somatic symptom maintenance, health care utilization following the initial appointment, and satisfaction with their medical care at follow-up. Each of these questions will advance the literature in this area.
