ABSTRACT Objective This study aimed to explore the impact of different parenting styles on the physical activity of childhood cancer survivors based on the parent‐based expansion of the theory of planned behavior. Methods This cross‐sectional study investigated 271 childhood cancer survivors and their parents in China. Results The path model was well fitted with χ 2 /df = 1.740, RMSEA = 0.052, GFI = 0.964, NFI = 0.958, IFI = 0.982, TLI = 0.969, CFI = 0.981. Positive parenting styles ( β = 0.181) directly affected the physical activity of childhood cancer survivors. Positive parenting styles indirectly influenced behavioral intention through both attitude ( β = 0.022) and perceived behavioral control ( β = 0.027), ultimately affecting physical activity in childhood cancer survivors. Parents who frequently encouraged or co‐participated in physical activity with children had children with significantly higher physical activity levels. Conclusions These findings highlight the critical role of positive parental style influence in fostering physical activity among childhood cancer survivors and suggest that interventions promoting positive parenting styles could enhance physical activity and overall well‐being in this vulnerable population.
