The Study On Psychosocial Risk Factors Of Aggression In Bipolar â…¡ Disorder

Objective:study of the psychosocial factors of aggressive behavior in BDII patients, to provide foundation of intervention in BD II patients. Methods:Investigating 104 cases of Han people diagnosed with bipolar type Ⅱ disorder,in Xinjiang Uygur Autonomous Region people’s Hospital Clinical Psychology Department and Xinjiang mental health Center,during July 2013 to December 2014. According to the Modified Overt Aggression Scale (MOAS) weighted score>4 and the table in the "physical attacks ">1, Barratt Impulsiveness Scale-11(BIS-11) score>70 divided into attack groups. MOAS weighted score≤4 and the table in the "physical attacks"=0, Barratt Impulsiveness Scale-11(BIS-11) score<70 divided into non-attack groups. Two groups were compared through General Survey table, and violence concept and the behavior questionnaire, and SCSQ and SSRS, PRCA, and EMBU for cross section investigation.And the questionnaire results are statistically analyzed by t test, Chi square test, rank-sum test and logistic regression. Results:Attacking groups think"may use violence to solve problems" more than non-attack group (χ2=21.872, P<0.01), attack group (11.52±7.15) have less positive coping strategies than non-attack (16.24±7.55; t=-3.267,P<0.01), attack group (13.325.33) have more negative coping strategies than non-attack group (10.94±4.22;t=2.531,P<0.05). Attack group’s total social support score(31.48±5.00; t=-2.691,P<0.01) and perceived social support score(18.74±3.49;t=-2.274,P<0.05) and the utilization of support (5.94±1.68;t=-2.741,P<0.01) are lower than the non-attack group. Attacks groups have more childhood physical abuse (59.40)than non-attack group (46.11; Z=-2.436,P<0.05). Attack group’s fathers to be more "Punishment and severe" parenting(t=2.379,P<0.05); their mother to be more "Reject and denial" (t=2.791,P<0.01)and "Punishment and Severe" parenting (t=2.306,P<0.05). The father’s overprotection was negatively related to negative coping strategies of attack group. Perceived social support of attack group was negatively correlated with father’s punishment and denied (P<0.05), and was negatively correlated with mother’s punishment (P<0.01). Objective support was negatively correlated with both fathers and mothers’s bias(P<0.05). Logistic regression results show that violent attitudes (OR=5.891), passive coping strategies(OR=1.198) are risk factors for impulsive aggressive behavior and positive coping strategies is a protective factor. Conclusion:Attack group think "can" use violence to solve problem more,and have more negative coping strategies, their perceived social support and the utilization of support is low. Attack group suffered physical abuse in childhood, their parentating style is excessive punishment and mother too much rejection. The history of childhood abuse and gross educational style of parents can affects the adult coping strategies and social support. Therefore, it is important for early intervention of bipolar II disorder with impulsive aggressive behavior to change the attitude of "can" use violence and to reduce the negative coping strategies, in the same time to increase the positive coping strategies.
