ABSTRACT

The purpose of this randomized controlled trial was to test an internet-delivered version of cognitive processing therapy (CPT) for the psychological distress associated with bullying victimization. The sample comprised 52 adults (i.e. 69.20% women; mean age = 43.37 (SD = 12.47); 3.85% ethnic minority) who self-identified as having a lifetime history of bullying victimization. Participants were randomized into three groups, which received 12 sessions of internet-delivered, therapist-guided, and content-modified version of CPT, 12 sessions of internet-delivered and therapist-guided stress management (SM), or a waitlist. Treatment outcomes included maladaptive trauma appraisals, symptoms of posttraumatic stress disorder (PTSD), depression, general anxiety and stress, social anxiety, and anger. Hierarchical linear modeling was used to analyse the data. Findings indicated that CPT was effective in reducing the strength of maladaptive appraisals related to bullying victimization and symptoms of PTSD compared to the waitlist and SM. SM outperformed CPT and the waitlist in reducing symptoms of depression, general anxiety, and stress. In conclusion, the results of this trial suggest that internet-delivered CPT is effective for the psychological distress and maladaptive appraisals associated with bullying victimization but that adaptions might be needed to target more effectively symptoms of anxiety and depression.

摘要

这项随机对照试验的目的是测试互联网提供的认知处理疗法 (CPT) 版本，以解决与欺凌受害相关的心理困扰。样本包括 52 名成年人（即 69.20% 的女性；平均年龄 = 43.37（SD = 12.47); 3.85% 的少数民族）自称有终生受欺凌史。参与者被随机分为三组，分别接受 12 次网络交付、治疗师指导和内容修改版本的 CPT，12 次网络交付和治疗师指导压力管理 (SM) 或候补名单。治疗结果包括适应不良的创伤评估、创伤后应激障碍 (PTSD) 的症状、抑郁、一般焦虑和压力、社交焦虑和愤怒。分层线性模型用于分析数据。研究结果表明，与候补名单和 SM 相比，CPT 在减少与欺凌受害和 PTSD 症状相关的不适应评估方面是有效的。SM 在减少抑郁症状方面的表现优于 CPT 和候补名单，普遍的焦虑和压力。总之，该试验的结果表明，互联网提供的 CPT 对与欺凌受害相关的心理困扰和适应不良的评估有效，但可能需要进行调整以更有效地针对焦虑和抑郁症状。
