Purpose: Most young adult cancer survivors (YACS) do not meet physical activity (PA) guidelines. Although PA can improve health and quality of life (QOL), few randomized controlled trials (RCTs) of PA interventions for YACS exist. We conducted a pilot RCT to test feasibility of a PA intervention among YACS. Methods: We recruited 18-39-year-olds (≥1 and Results: All feasibility criteria were met: We recruited 50 YACS, intervention participants wore the Fitbit on the majority of intervention days (82.9%), ≥75% of participants completed questionnaires at baseline (100%) and follow-up (93.9%). Exploratory analyses, adjusted for wave, accelerometer wear time, race, and income, showed significant group differences for change in ST (-52.4 vs. 2.5 minutes/day; p = 0.002) but no change in moderate-to-vigorous intensity PA (0.0 vs. -0.2 minutes/day; p = 0.40), comparing intervention participants to controls. The intervention (vs. control) group had a greater increase in fatigue interference (p = 0.03). No other significant differences in SDT or QOL measures were found. Conclusion: This Fitbit and Facebook-based PA intervention was feasible to YACS, with promising effects on reducing ST, and warrants a fully powered RCT. Clinical Trial Registration no.: NCT03233581.
