Purpose: This study sought to develop a quantitative understanding of factors that reduce perceived isolation and marginalization among physical educators. A conceptual model for the relationships among study variables was developed. Method: Data were collected through an online survey completed by 419 inservice physical educators (210 females, 209 males, 93.60% Caucasian). Variables included perceived mattering, resilience, personal accomplishment, as well as isolation and marginalization. Primary data analyses included structural equation modeling to test the hypothesized relationships in the conceptual model. Results: The structural equation model fit was good, X[superscript 2](315) = 669.38, p < 0.001, RMSEA = 0.05 (90% CI = [0.05, 0.06], p = 0.285), SRMR = 0.05, NNFI = 0.93, CFI = 0.94. After removing non-significant regression pathways, the structural model generally confirmed the study hypotheses. Discussion/Conclusion: Enhancing personal accomplishment and resilience helps to foster perceptions of mattering, which reduces physical educators' perceived isolation and marginalization.
