Brain tumor survivors often face many difficulties in social competence. One of which being, facing impairment in interpersonal trust. They often recognize trust as being an important aspect of relationships, but they don’t mention it as being present in their own relationships. A lack of trust in relationships may have a negative impact on relationships quality by slowing the development of a more intimate, meaningful, and fulfilling bond, which could negatively affect the social adjustment and quality of life of pediatric brain tumor survivors. Lower levels of trust have also been known to be related to higher levels of loneliness. To date, there have been no quantitative studies examining trust in pediatric brain tumor survivors and how loneliness might relate to this. To address this gap, this study will be the first to quantitatively look at trust levels of pediatric brain tumor survivors compared to children from the community.  Information on other aspects related to social competence and trust will be looked at (e.g., socioeconomic status, loneliness, social adjustment). Knowing more about trust in pediatric brain tumor survivors is important as it will inform us about whether working on trust in social competence interventions is of interest.
