Parental control can affect a children’s attitudes and their ability to cope with adversity after they become adults. This study explored the influence mechanism of parental control on adversity growth and the moderating effect of a growth mindset through a questionnaire survey completed by 354 Chinese college students born in one-child families. Hierarchical regression and structural equation analysis results show that parental control negatively affects adversarial growth, and self-identity plays a mediating role between parental control and adversarial growth. A higher degree of parental control will reduce the individual’s self-identity, which is not conducive to the occurrence of adversarial growth. A growth mindset negatively moderates the indirect effect of parental control on adversarial growth through self-identity. Individuals with a strong growth mindset have reduced negative effects of parental control on self-identity and adversarial growth. Even in countries with collectivist cultures, parental controls also need to be implemented carefully, and controlling parenting styles may be detrimental to individual growth after adversity. At the same time, it is necessary to consciously cultivate children’s growth mindsets, so as to inhibit the negative impact of parental control on adversarial growth.
