The Effect of COVID-19 Pandemic on Adolescent and Young Adult Cancer Patients and Survivors

Assessed per responses to the 12 questions pertaining to COVID-19 specific psychological stress within the adolescent and young adults (AYA) Cancer Survivor COVID-19 Survey section titled, "COVID-19 Related Distress (Emotional and Physical Reactions) and Health Behaviors.'' This survey includes both a 5-level Likert scale for the respondent's current level of concern (Not at all, A little, Neutral, A lot, Very Much), plus an ordinal 3-level scale for the respondent to rate the perceived level of change compared to before COVID-19 (Less, Same, More). Responses to individual questions will be summarized at each time point as means (for the Likert scale) and percentages (for discrete levels of change), together with 95% confidence intervals. For each question, will also summarize the percentages of patients in each group checking one of the 3 levels (Less, Same, More) indicating whether they perceived a change in that question since before COVID-19.

Will be summarized by group and time point. Associations between endpoints and demographic, treatment-related and resilience variables, as well as differences among groups will be assessed by t-test, analysis of variance or Chi-square test. Non-parametric tests (Wilcoxon rank sum, Kruskal-Wallis, Fisher's exact) will be employed when appropriate. Regression models (e.g., linear, logistic etc.) will also be employed. Change from baseline to subsequent time points in Likert scores will be modeled by mixed-effect models, while blocking on patient to control for repeated measures. Models will include baseline demographic, treatment-related, and resilience factor variables as covariates.

Will be separately modeled by logistic regression with relation to group and time point as well as demographic and cancer characteristics in order to assess factors associated with non-response and to assess associated bias. Other statistical approaches might be used as appropriate.
