This study evaluated the specific effectiveness of cognitive-behavior therapy (CBT) combined with medication tapering for benzodiazepine discontinuation among generalized anxiety disorder (GAD) patients by using a nonspecific therapy control group. Sixty-one patients who had used benzodiazepines for more than 12 months were randomly assigned to the experimental conditions. Nearly 75% of patients in the CBT condition completely ceased benzodiazepine intake, as compared with 37% in the control condition. Results of the 3-, 6-, and 12-month follow-ups confirmed the maintenance of complete cessation. Discontinuation rates remained twice as high in the CBT condition. The number of patients who no longer met GAD criteria was also greater in the CBT condition. The addition of specific CBT components thus seemed to facilitate benzodiazepine tapering among patients with GAD.
本研究通过使用非特异性治疗对照组,评估了认知行为疗法(CBT)联合逐渐减少苯二氮䓬类药物用量对广泛性焦虑症(GAD)患者停用苯二氮䓬类药物的具体效果。61名使用苯二氮䓬类药物超过12个月的患者被随机分配到不同的实验条件组。接受CBT治疗的患者中近75%完全停止了苯二氮䓬类药物的摄入,而对照组这一比例为37%。3个月、6个月和12个月的随访结果证实了完全停药状态的维持。CBT组的停药率仍高出两倍。在CBT组中,不再符合GAD标准的患者数量也更多。因此,添加特定的CBT成分似乎有助于GAD患者逐渐减少苯二氮䓬类药物的用量。
