The opportunity for psychology trainees to provide services on multidisciplinary teams in the pediatric medical setting offers unique opportunities and ethical challenges (e.g., deciding which information to disclose to medical team). The developmental process of integrating ethical principles learned from general ethics training in the classroom with ethical decision making for issues that present in the pediatric medical setting can be challenging for trainees. In this article the authors will highlight ethical issues related to working in a pediatric medical setting. In particular, ethical issues unique to the pediatric setting are highlighted, including (a) working with children with medical conditions and potentially life-threatening illnesses and (b) working on multidisciplinary teams. Case examples illustrate potential ethical concerns, and suggestions for both trainees and supervisors are discussed.
