先前的研究报道，在暴露疗法中加入认知重构（CR）并不能提高创伤后应激障碍（PTSD）的治疗效果。本研究调查了当提供暴露疗法时，CR能在多大程度上增强治疗反应。作者随机分配118名患有PTSD的平民创伤幸存者接受8次单独治疗，分别为(a)想象暴露（IE）， (b)体内暴露（IVE）， (c) IE联合IVE (IE/IVE)，或(d) IE/IVE联合CR （IE/IVE/CR）。在6个月的随访评估中，IE/IVE/CR组的PTSD患者（31%）少于IE（75%）、IVE（69%）和IE/IVE（63%）组。IE/IVE/CR条件在PTSD和抑郁症状方面比其他条件产生更大的效应量。这些发现表明，将CR与暴露疗法结合治疗PTSD患者可能达到最佳治疗效果。
Previous studies have reported that adding cognitive restructuring (CR) to exposure therapy does not enhance treatment gains in posttraumatic stress disorder (PTSD). This study investigated the extent to which CR would augment treatment response when provided with exposure therapy. The authors randomly allocated 118 civilian trauma survivors with PTSD to receive 8 individually administered sessions of either (a) imaginal exposure (IE), (b) in vivo exposure (IVE), (c) IE combined with IVE (IE/IVE), or (d) IE/IVE combined with CR (IE/IVE/CR). There were fewer patients with PTSD in the IE/IVE/CR (31%) condition than the IE (75%), IVE (69%), and IE/IVE (63%) conditions at a 6-month follow-up assessment. The IE/IVE/CR condition resulted in larger effect sizes than each of the other conditions in terms of PTSD and depressive symptoms. These findings suggest that optimal treatment outcome may be achieved by combining CR with exposure therapy in treating PTSD patients.
