Aim: Aim was to determine the relationship between biological maturation and physical activity of female adolescents regarding the mediating role of psychological factors. Methods: Method was correlational and statistical population included all of the 31522 female students of public junior schools, in Mazandaran Province in 2016-2017, using multi-stage random sampling method, finally 630 students were selected based on a ratio of 5 to each item with probability of sample loss. The tools included Khamis–Roche (1994) Adult Stature Estimation, Xiaomi Mi Band (2014) Pedometer, Seca 213 (2015) Stadiometer, Seca 813 (2015) Robusta Scales, Marsh (2010) Physical Self-description Questionnaire, Rosenberg (1965) Self-esteem Scale, Littelton, Axsom & Pury (2005) Body Image Concern Inventory and Simon & Smoll, (1974) Attitude toward Physical Activity Inventory. After excluding 57 respondents based on exclusion criteria, data were analyzed using structural equation modeling. Results: The data analysis showed a significant inverse relationship between biological maturation and physical activity (β= -0.289, P= 0.001). The structural equation modeling results showed a goodness of fit of model (GOF= 0.46) and there was significant indirect path coefficient between biological maturation and physical activity by mediating attitudes toward physical activity (β= -0.150, P= 0.012), self-esteem, (β= -0.091, P= 0.015), physical self-concept (β= -0.062, P= 0.016) and body image satisfaction (β= -0.009, P= 0.019). Conclusion: To promoting health-related behaviors, programs need to to be designed that girls can evaluate puberty as a normal and attractive transition to adulthood and to accept individual differences and differences in appearance.
