Objective To understand the situation of medical students' social adaptability and analyze its relationship with their family upbringing style.Methods A cross-sectional study was adopted,and the random sampling method was used to selected medical students as targeted population in a medical university in Jilin City.Parenting Style Assessment Scale and Social Adaptation Diagnostic Scale were applied to know the family rearing styles and social adaptability status of medical college students.Results Among the 198 responders,the proportion of good and strong social adaptability among medical college studies accounted for only 8.1％ (16) and 2.0％ (4);The social adaptation ability of the urban students and the only child students was higher than that of the rural and non only child students (P＜0.05);In parental rearing pattems,regardless of sex,whether students were the only child and where their census register was,emotional warmth and understanding were all positively correlated with medical students' social adaptation ability (P＜0.05),while refusal and denial were negatively correlated with medical students' social adaptation ability (P＜0.05);In addition,the punishment,severe over protection and other parenting styles also showed a certain degree of negative correlation with social adaptability(P＜0.05).Conclusion The social adaptability of medical students is poor,and their parenting styles was correlated with their social adaptation ability.Parents should give their children warmth and understanding,rather than rejection,denial,punishment,and overprotection,which will help to improve medical students' social adaptability.
