Parental cancer can cause substantial behavioral and emotional distress in both parent and child. Parents struggle with talking with their child about their cancer and supporting the child during treatment. Over 73% of patients with children desire information and services to support their children yet only 9% of these families report receiving this support. The purpose of this study is to evaluate the Wonders & Worries psychosocial intervention designed for children ages 5-14 who have a parent diagnosed with early stage cancer.This study is a randomized controlled clinical trial (RCT) evaluating the Wonders & Worries group and individual intervention for school age children (5 -14 years old) who have a parent with cancer. Families will be enrolled at the time of initial parent consultation, given informed consent, and then randomized either to the intervention group of 30 families or the wait-listed control group of 30 families. Both groups will be given a series of standardized validated assessment instruments including the Revised Children's Manifest Anxiety Scale (RCMAS), the Child Behavior Checklist (CBCL), and the Family Communication Scale FACES IV at baseline, post intervention, and 8 week follow up. Upon completion of the follow up measures, families in the wait-listed control group will be enrolled into the intervention. Parent exit interviews for both groups will be used to measure parent-reported child outcomes and program utility.
