Objective To study the development of impulsive personality in junior middle school students of Changsha, and to explore its relationship with parental rearing patterns. Methods 409 students were investigated by Egna Minnenav Barndoms Uppfostran ( EMBU ) and Barratt Impulsivity Scale ( BIS-11 ). Results Male and female had significant difference in attention impulsiveness scores((20.56 ±3.60) vs ( 19.63 ±3.07) , P< 0.01). Grade 7 and Grade 9 had significant difference in attention and motor impulsiveness scores((20. 58 ± 3.47)vs (19.63 ±3.46) , P<0.05;(20. 31 ±4.37)vs (21.75 ±4.00) , P< 0.01). Parental warmth and understanding was negatively correlated with attention , non-planning and total scores of impulsiveness ( r= - 0. 23 ～ -0.33, P<0.01). Parental refusal and rejection was positively correlated with total and factors of BIS-11 ( r = 0. 23 ～0. 33 , P<0. 01 ) . Parental punishment and rigor was positively correlated with motor and total scores of im-pulsiveness( r = 0.22 -0.26, P<0.01). Parental over-interference and overprotection was positively correlated with motor impulsiveness ( r = 0. 23 ～0. 34, P<0. 01). Mother's punishment and rigor was positively correlated with attention impulsiveness( r = 0.22, P<0. 01 ). Father' s overprotection and Mother' s over-interference and overprotection was positively correlated with total scores of impulsiveness ( r = 0. 23 ;0. 25 , P < 0. 01) . Stepwise regression analysis revealed that factors and total of BIS-11 explained by patterns rearing were 12% ,14% ,15% and 19% . Conclusion Rearing patterns can severely impact the development of impulsive personality. Impulsive personality is positively predicted by parental rearing patterns.
