Posttraumatic stress disorder (PTSD) symptoms may impact cognitive processes underlying encoding and retrieval of positive memories. Contractor and colleagues thus proposed a Positive Memory-PTSD model outlining hypothesized pathways (e.g., improved cognitions and affect) linking active processing of positive memories and PTSD symptoms. In the current study, we empirically explored direct and indirect pathways of the Positive Memory-PTSD model including relations between presence/types of processing memory methodology, posttrauma maladaptive cognitions, positive/negative affect, and PTSD symptom severity. We randomly assigned 65 students reporting trauma histories to time-matched narrating (identifying and sharing details of elicited positive memories), writing (identifying and writing details of elicited positive memories), or control conditions. Participants completed self-report measures (T0) and repeated their assigned task condition and self-report measures 6-8 days later (T1). Half-longitudinal models demonstrated direct associations of (1) being in the narrating versus other conditions with decreases in posttrauma maladaptive cognitions and negative affect, and increases in positive affect; and (2) increases in posttrauma maladaptive cognitions and negative affect with greater PTSD symptom severity. Although, when controlling for posttrauma maladaptive cognitions and negative/positive affect, being in the narrating versus other conditions was associated with decreases in PTSD symptom severity, these constructs did not explain examined relations. Results suggest beneficial impacts of narrating positive memories on PTSD symptom severity (accounting for cognitions/affect) and improved cognitions/affect, and a need to examine moderating variables (e.g., emotion regulation) in the Positive Memory-PTSD model.

创伤后应激障碍（PTSD）症状可能会影响积极记忆编码和提取背后的认知过程。因此，承包商及其同事提出了一个积极记忆-PTSD模型，概述了将积极记忆的主动加工与PTSD症状联系起来的假设途径（例如，认知和情感改善）。在当前的研究中，我们实证探索了积极记忆-PTSD模型的直接和间接途径，包括加工记忆方法的存在/类型、创伤后适应不良认知、积极/消极情感与PTSD症状严重程度之间的关系。我们将65名有创伤史的学生随机分配到时间匹配的叙述组（识别并分享引出的积极记忆的细节）、写作组（识别并写下引出的积极记忆的细节）或对照组。参与者完成了自我报告测量（T0），并在6-8天后重复他们分配的任务条件和自我报告测量（T1）。半纵向模型表明：（1）与其他条件相比，处于叙述组与创伤后适应不良认知和消极情感的减少以及积极情感的增加直接相关；（2）创伤后适应不良认知和消极情感的增加与更高的PTSD症状严重程度相关。尽管在控制创伤后适应不良认知和消极/积极情感时，与其他条件相比，处于叙述组与PTSD症状严重程度的降低相关，但这些构念并不能解释所研究的关系。结果表明，叙述积极记忆对PTSD症状严重程度（考虑认知/情感）以及认知/情感改善有有益影响，并且需要在积极记忆-PTSD模型中检验调节变量（例如，情绪调节）。（PsycInfo数据库记录（c）2022美国心理学会，保留所有权利）
