Borderline Personality Disorder And Drug Addiction Disorders In Patients With Defense Mechanisms

The research want to study on two problems: first, comorbidity of drug addictivedisorder; Second, defensive mechanisms of this group of patient. We used PDF4+andSCID-Ⅱto distinguish addictive patients with BPD from addictive patients withoutBPD. Our patients are form two government institution respectively in Foshan andShenzhen. They are all enforced to get rid of drug problems. There are 139 patientswith BPD and 165 patient without BPD. We use DSQ and DES in these two group ofpatients to find difference of cognitive distortion and dissociative experience betweenthem. The result is patient with BPD have more possibility to attempt suicide(x~2=23.907, p＜0.01), have more chance to be told that they are in bad health and havelower education level, especially among female patients. In subscales PD, SZD, SPD,HPD, NPD, APD, AVD, DPD, OPD of PDQ4+, patients with BPD's score aresignificant higher that patients without BPD's score. The difference still exisst aftergender stratification. Step-regression Logistic analysis shows gender(OR=0.413, 95％CI: 0.228～0.747), suicide attempt (OR=3.882, 95％CI; 2.140～7.040)are the riskfactors of comorbidity and its protective factor is education level. Patients with BPD'sscores on immature cognitive distortion are significant higher than patients withoutBPD's score. The difference still exists after gender stratification. Step-regressionLogistic analysis shows passive attact (OR=1.623, 95％CI: 1.234～2.135, p＜0.05)and unconscious appearance (OR=1.281, 95％CI: 1.006～1.630, p＜0.05)are riskfactors of comorbidity and its protectively factors are humorous(OR=0.780, 95％CI: 0.639～0.951, p＜0.05) and accompanying tendency (OR=0.834, 95％CI:0.704～0.988, p＜0.05). More patients with BPD have higher dissociative level andMore patients without BPD have low dissociative level, the difference is significant(x~2=9.492, p＜0.01). Concurrent patients' total score of DES is higher thannon-concurrent patients'. The difference is significant before and after genderstratification. Difference of score of absorption and imaginative involvement is alsosignificant before and after gender stratification. Difference of score of amnesia issignificant, but after gender stratification, no difference exists any more. In our practical work, we must pay more attention on diagnose of comorbidity understandthe defensive mechanisms, and use integrated method of intervention.
