Of them, 87(87%) were women and 13(13%) were men. All scales had greater than 0.70 alpha reliability coefficients. The values of skewness for all scales ranged from 0.10 to 0.86. Permissive parenting style had positive correlation with histrionic (p< 0.05), narcissistic (p< 0.05) and antisocial personality disorders (p< 0.01). Authoritarian parenting had positive correlation with early maladaptive schemas (p< 0.01) and depressive personality disorder (p< 0.05). Conclusion: Both permissive and authoritarian parenting styles led to personality disorders among offspring in the adult phase of their lives.
