ABSTRACT

74Distress tolerance (DT; perceived or actual ability to tolerate aversive physical or emotional states) is related to both posttraumatic stress disorder (PTSD) symptoms and substance use disorders (SUD). This investigation evaluates self-report and behavioral measures of DT as potential predictors of PTSD and SUD cognitive-behavioral therapy outcomes. Participants included 41 treatment-seeking adults (53.7% women; 73.2% African American; M_age = 44.90, SD = 9.68) who met at least four symptoms of DSM-5 PTSD and DSM-IV substance dependence, assessed via structured interviews. At baseline (pre-treatment), participants completed the Distress Tolerance Scale (DTS), Mirror-Tracing Persistence Task (MTPT), Breath Holding task, and Paced Auditory Serial Addition Task. The Clinician-Administered PTSD Scale for DSM-5 severity scores and percent days of primary substance use, measured via Timeline Follow-back, were used as indicators of PTSD symptoms and substance use, respectively. Covariates included treatment condition, baseline PTSD symptom severity, and baseline substance use. Lower perceived DT at baseline (DTS total score) was associated with higher PTSD symptom severity at end-of-treatment. Lower behavioral DT at baseline (MTPT duration) was associated with higher substance use at the conclusion of treatment (i.e. proportion of number of use days to total number of days between two final treatment sessions).

摘要

74 压力耐受性（DT；感知或实际耐受厌恶的身体或情绪状态的能力）与创伤后应激障碍 (PTSD) 症状和物质使用障碍 (SUD) 相关。这项调查评估了 DT 的自我报告和行为测量作为 PTSD 和 SUD 认知行为治疗结果的潜在预测因素。参与者包括 41 名寻求治疗的成年人（53.7% 女性；73.2% 非裔美国人；M_年龄 = 44.90，SD  = 9.68），他们至少满足DSM-5 PTSD 和DSM-IV 的四种症状物质依赖，通过结构化访谈进行评估。在基线（治疗前），参与者完成了痛苦耐受量表（DTS）、镜像追踪持久性任务（MTPT）、屏气任务和有节奏的听觉串行添加任务。临床医生管理的 DSM-5 严重程度评分和主要物质使用百分比天数的临床医生管理的 PTSD 量表，通过时间线跟踪测量，分别用作 PTSD 症状和物质使用的指标。协变量包括治疗条件、基线 PTSD 症状严重程度和基线物质使用。基线时较低的感知 DT（DTS 总分）与治疗结束时较高的 PTSD 症状严重程度相关。基线时较低的行为 DT（MTPT 持续时间）与治疗结束时较高的物质使用相关（即
