Adolescents/young-adult (AYA) cancer patients are a psychosocially at-risk group as they are often less well-studied than other age cancer cohorts. Therefore, they experience disparities in access to developmentally informed treatment. Social support has been determined as an important aspect of AYAs' cancer experience, but additional research was needed to describe specific behaviors AYAs found helpful and to explore how AYAs seek opportunities for additional support. As part of a larger qualitative study, study aims were to determine how AYAs (ages 15-26) cope during cancer treatment and examine how social support interacts with individual AYA coping. Participants included 10 AYA cancer patients undergoing treatment (mean age = 18.9 years) and 10 parents (mean age = 45.6 years). Descriptively, participants scored within the normal to high range on measures of hope, depression/anxiety/stress, quality of life, and social support. Participants completed semi-structured, audio-recorded interviews that were transcribed and coded as generated. Qualitative analysis was guided by principles of grounded theory and utilized the constant comparative approach. Themes within social support groups included presence, distraction, positive attitude, and maintaining AYA autonomy, communication, and advocacy. Results suggest social supports provide additional coping resources for AYAs with cancer through supplementing individual coping strategies. Future directions/implications for intervention/treatment are discussed.Children 2020, 7, 2 2 of 25 quality of life [3,4], lower scores of health competence (e.g., health perceptions, cognitive competence, and autonomy), significantly greater psychological distress, fewer positive health beliefs [5], and more social problems [6] than individuals diagnosed during school age (ages 6-12) or earlier. Even for medically healthy and typically developing individuals, the adolescent developmental stage poses distinct challenges, which can be further complicated by the introduction of a chronic illness such as cancer [6][7][8].Social support through family, friends, healthcare providers, and other individuals [8] appears to be one of the most important and beneficial aspects for adolescents and young adults undergoing cancer treatment. Both parental and friend/peer support appear to have a unique and important influence on AYAs coping with cancer, but findings are mixed about which of these relationships are most meaningful [9][10][11][12][13]. Social support has been shown to be important for most cancer populations; however, few studies have explicitly examined which actions and behaviors are the most helpful, particularly for AYAs undergoing treatment. Furthermore, fewer studies describe behaviors from a wide variety of social supports, and even fewer examine findings communicated directly from AYAs themselves.As part of a larger qualitative project focused on coping and hope theory in AYA cancer patients, researchers examined how a wide range of social supports provide assistance for this d...
