SUMMARY
This paper aims to examine the relationship between five dimensions of personality characteristics and mental health of parents on parenting styles (authoritative, authoritarian, permissive) is. The research method is descriptive and correlational, and by using Morgan table (1970), 92 parents with preschool children in 2015 were selected as a sample through random cluster sampling; marital status of not being divorced as a factor was considered, too. Research Tools are Short Form NEO Questionnaire and 28 items General Health Questionnaire (GHQ) and Baumrind Parenting Style Questionnaire (1972). The findings show that there is significant relationship between neuroticism personality dimension with (authoritarian and permissive) styles and an inverse relationship with the (authoritative) style. There is significant relationship between extraversion and passionate personality with (permissive and authoritative) styles and inverse relationship with authoritarian (autocratic) style. There is significant relationship between agreeableness personality and (authoritative) style and inverse relationship with other parenting styles. There is significant relationship between (responsive) personality and parenting styles (authoritarian, authoritative, permissive). There is a significant relationship between mental health and (permissive and authoritative) parenting styles and an inverse relationship with (authoritarian) style. There is an inverse relationship between mental health and (neuroticism, passionate) personality dimensions and a significant relationship with the other personalities. Healthy personality, as well as mental health of parents, is influential factors in (authoritative) parenting style. In addition, by applying the right education style, many mental disorders and behavioral disorders in children can be prevented.
