RecruitingBehavioural interventionFeasibility and Acceptability of Internet-based Parent-child Interaction Therapy (I-PCIT) in Pediatric CancerThis study is being done to learn whether a telehealth intervention called "Internet-Based Parent Child Interaction Therapy," or I-PCIT," can help parents improve the child's behavior if the child currently or previously went through cancer treatment. Parents who choose to be in this study will complete a survey to help researchers figure out if the parent is eligible for the larger study. If a parent is eligible for the larger study and chooses to participate, if so, the participants will be randomly assigned to either receive the I-PCIT intervention now or to be on a waitlist and begin I-PCIT in 5-6 months. The whole study consists of completing I-PCIT sessions with a clinician and completing 3-4 follow-up surveys after the initial screener survey.
