Recent meta-analyses point towards cognitive impairments in obsessive-compulsive disorder (OCD), particularly in such executive function subdomains as planning and organization. Scant attention has focused on cognitive remediation strategies that may reduce cognitive dysfunction, with a possible corresponding decrease in symptoms of OCD.
The aim of this study was to assess the implementation of a standardized cognitive remediation program, Goal Management Training (GMT), in a pilot sample of individuals with OCD.
Nineteen individuals with a primary DSM-5 diagnosis of OCD were randomized to receive either the 9-week GMT program (active group; = 10) or to complete a 9-week waiting period (waitlist control; = 9). Groups were assessed at baseline, post-treatment, and 3-month follow-up. The assessment comprised neuropsychological tasks assessing a variety of cognitive domains, and subjective measures of functioning and of symptom severity.
The active condition showed significant improvements from baseline to post-treatment on measures of inattention, impulsivity, problem-solving, and organization compared to controls. Moreover, whereas the active group reported a significant improvement in subjective cognition over the course of treatment, no such improvement emerged in the waitlist group over this same period. Neither group showed improvement on indices of depressive, anxiety, or OCD-related symptom severity.
The results of this small pilot investigation indicate that, although promising, this protocol requires several modifications to be best suited for this population. Replication of these findings is awaited, with current results potentially limited by sample characteristics including motivation to seek and complete treatment, and high attrition at 3-month follow-up ( = 6 completers).

近期的荟萃分析表明强迫症(OCD)存在认知障碍,尤其是在计划和组织等执行功能子领域。很少有注意力集中在可能减少认知功能障碍以及相应减少强迫症症状的认知矫正策略上。
本研究的目的是在强迫症患者的一个试点样本中评估标准化认知矫正项目目标管理训练(GMT)的实施情况。
19名被主要诊断为DSM-5强迫症的个体被随机分为接受为期9周的GMT项目(实验组;n = 10)或完成为期9周的等待期(候补对照组;n = 9)。在基线、治疗后和3个月随访时对两组进行评估。评估包括评估各种认知领域的神经心理学任务以及功能和症状严重程度的主观测量。
与对照组相比,实验组在注意力不集中、冲动性、解决问题和组织能力的测量上从基线到治疗后有显著改善。此外,虽然实验组在治疗过程中报告主观认知有显著改善,但候补对照组在同一时期没有出现这种改善。两组在抑郁、焦虑或强迫症相关症状严重程度指标上均未显示出改善。
这项小型试点调查的结果表明,尽管有前景,但该方案需要进行一些修改以最适合该人群。期待这些结果的重复验证,目前的结果可能受到样本特征的限制,包括寻求和完成治疗的动机,以及3个月随访时的高失访率(n = 6名完成者)。
