RESUMO
Introduction: Adolescents and young adults diagnosed with cancer (AYAs) are under-represented in research. The Internet and social media could increase the reach of recruitment efforts but may impact sample characteristics. This study evaluated the characteristics of AYAs recruited in-person at an urban hospital versus the Internet in terms of their sociodemographic and medical characteristics, and psychosocial wellbeing, and offers recommendation for increasing the inclusivity and representativeness of research samples. Methods: Participant data from a cross-sectional survey of AYAs in Canada were evaluated. In-person hospital recruitment used a registry to identify patients attending ambulatory clinics. Internet recruitment included notices on hospital, team members', and community partners' social media channels, and email newsletters. Independent sample t-tests and Chi-squared tests were used to identify differences in participant sociodemographic, medical, and psychosocial characteristics based on recruitment source. Results: Of 436 participants, 217 (49.8%) were recruited in-person and 219 (50.2%) online. Online participants were more likely: to be white (p < .001), women (p < .001), and Canadian-born (p < .001); to speak English at home (p < .001), live alone (p = .001) and live in rural settings (p = .014); and to be farther from diagnosis (p = .023), diagnosed with breast cancer (p < .001), and cancer free (p < .001) compared to the hospital sample. Online participants also reported higher anxiety, depression, and loneliness (p < .001), and lower social support (p < .001), self-efficacy for coping with cancer (p < .001), and life satisfaction (p = .006). Conclusions: Online recruitment yielded a more geographically diverse but less sociodemographically diverse sample of AYAs who were farther from diagnosis and had poorer psychosocial wellbeing than in-person recruitment at an urban hospital. Future research efforts should consider partnering with under-represented communities and using targeted and stratified online and in-person recruitment strategies to achieve an inclusive and representative sample of AYAs.
