abstract="Background and Objectives Evidence links posttraumatic stress disorder (PTSD) with positive memory characteristics. To extend this research, we utilized daily diary data to examine (1) concurrent/lagged associations between daily PTSD symptom severity and positive memory vividness/accessibility; and (2) associations between baseline-assessed positive memory characteristics and changes in PTSD symptom severity over time.Design and Methods A sample of 238 trauma-exposed participants (Mage = 21.19 years; 86% women) completed baseline and 10 daily measures of PTSD symptoms and positive memory characteristics. Multilevel models covaried for gender, number of trauma types, and number of completed surveys.<br><br>RESULTS Days with greater PTSD symptom severity than an individual's average associated with less vividness (b = −0.02, p <.001) and accessibility (b = −0.02, p <.001) of the positive memory on the same day. Days with greater positive memory vividness (b = −1.06, p <.001) and accessibility (b = −0.93, p <.001) than an individual's average associated with less PTSD symptom severity on the same day. There were no significant lagged associations between these constructs. There were significant interactions between baseline-assessed psychological distance and time (b = −0.04, p =.042) and between baseline-assessed visual perspective and time (b = 0.05, p =.023) on PTSD symptom severity across days.<br><br>CONCLUSIONS Findings inform positive memory intervention targets for PTSD and provide impetus for longitudinal investigations on their inter-relations.<p /> <p>Language: en</p>",
