Indicators of developmental status among adolescents and young adults with cancer: Perceived adult status, social milestones, and health-related quality of life

ObjectiveDevelopmental disruption contributes to poor psychosocial outcomes among adolescents and young adults (AYAs) with cancer, though indicators of AYAs' developmental status are not well understood. In this study, we describe perceived adult status as a novel developmental indicator and examine its associations with social milestones achievements and health-related quality of life (HRQoL). MethodsFor this secondary analysis, AYAs with cancer were recruited using a 2 (on/off treatment) x 2 [emerging adults (EAs) 18-25 years-old, young adults (YAs) 26-39 years-old] stratified sampling design through an online research panel. Surveys assessed perceived adult status (i.e., self-perception of the extent to which one has reached adulthood), social milestones (marital, child-rearing, employment, educational status), demographic and treatment characteristics, and HRQoL. Generalized linear models tested associations between perceived adult status, social milestones, and HRQoL. ResultsAYAs (N = 383; M-age = 27.2, SD = 6.0) were majority male (56%) and treated with radiation without chemotherapy (37%). Most EAs (60%) perceived they had reached adulthood in some ways; most YAs (65%) perceived they had reached adulthood. EAs who perceived they had reached adulthood were more likely to be married, raising a child, and working than EAs who did not perceive they had reached adulthood. Among EAs, lower perceived adult status was associated with lower HRQoL when accounting for social milestones. Among YAs, perceived adult status was not associated with social milestones and neither perceived adult status nor social milestones were associated with HRQoL. ConclusionsPerceived adult status may be a useful developmental indicator for EAs with cancer. Findings highlight unique developmental needs of EAs and utility of patient perspectives for understanding developmental outcomes.
