Objectives To explore the mediating role of self-acceptance between parenting style and social phobia， so as to provide evidence for the formulation of intervention plan. Methods A total of 1 253 students from secondary vocational schools were recruited as the research subject. A cross-sectional study was carried out with the Brief Social Phobia Scale（ BSPS）， the Self-Acceptance Questionnaire（ SAQ） and Egma Minnen av Bardndosnauppforstran（ EMBU）. The structure equation model and bootstrap were adopted to verify the mediating effect of self-acceptance between parenting style and social phobia. Results Apart from parental preference factor， social phobia is significantly correlated with 9 factors of parenting style（ Ps＜0.01）. Social phobia is significantly negatively correlated with self-acceptance and self-assessment（ Ps＜ 0.01）. Selfacceptance and self-assessment are significantly correlated with most factors of parenting style（ Ps＜0.01）. The structural equation model showed that self-acceptance played a fully mediation role between parenting style and social phobia（ χ2/df=5.50， RMSEA=0.060， CFI=0.973， TLI=0.961， SRMR=0.047）. Bootstrapping indicated that the mediating effect of self-acceptance accounted for 76.47%. Conclusions Self-acceptance has a fully mediating effect between parenting style and social phobia.
