Abstract
Individuals with posttraumatic stress symptoms (PTSS) report difficulties engaging with positive autobiographical memories. Extending this line of research, we examined daily-level concurrent and lagged associations between PTSS severity and positive memory characteristics (vividness, coherence, accessibility, time perspective, sensory details, visual perspective, emotional intensity, sharing, distancing, and valence). The sample included 88 trauma survivors (Mage = 39.89 years, 59.1% female) who completed seven daily measures of PTSS and positive memory characteristics. Multilevel models examined concurrent and lagged associations between PTSS severity and positive memory characteristics. The results indicated that days with higher PTSS severity were associated with less accessibility, β = -.21, p < .001; less visual perspective, β = -0.13, p = .034; and lower positive valence of the memory, β = -.19, p = .003, as well as more emotional intensity associated with, β = .13, p = .041, and more distancing from, β = .21, p < .001, the memory. Supplemental lagged analyses indicated that higher previous-day PTSS severity was associated with more next-day distancing from, β = .15, p = .042, and sensory details of, β = .17, p = .016, the memory. Findings suggest that individuals with more severe PTSS have difficulties accessing positively valenced memories from a first-person perspective, are more distant from the recalled positive memory, and report more emotional intensity when retrieving the memory. Thus, improving access to and reducing distance from positive autobiographical memories, as well as addressing emotional intensity surrounding the retrieval of these memories, may be potential clinical targets for PTSS interventions.

Abstract
BACKGROUND Evidence links posttraumatic stress disorder (PTSD) symptoms and features of positive autobiographical memories (accessibility, vividness, coherence, sharing, emotional intensity, distancing). There is a knowledge gap on how adverse childhood experiences (ACEs) and benevolent childhood experiences (BCEs) may influence these relationships. OBJECTIVES The current study explored whether the number ACEs or BCEs moderated associations between PTSD symptom severity and features of positive autobiographical memories. DESIGN AND METHODS The sample included 124 student military veterans who had experienced a trauma (Mage = 33.90; 77.4% male; 75.0% White). RESULTS Path analyses showed more PTSD symptom severity was significantly associated with less positive autobiographical memory vividness (β = -0.26, p = .019, R2 = 0.06). Further, the number of ACEs moderated the relationship between PTSD symptom severity and positive autobiographical memory accessibility (β = -0.25, p = .023, R2 = 0.10) and vividness (β = -0.20, p = .024, R2 = 0.10). Among individuals with more ACEs (1 SD above the mean) compared to those with fewer ACEs (1 SD below the mean), less accessibility and vividness of positive autobiographical memories was associated with greater PTSD symptom severity. The number of BCEs was not a significant moderator. CONCLUSIONS Positive memory-based interventions may be particularly useful to address PTSD symptoms among military veterans with a history of childhood adversity.

Abstract
Trauma survivors with posttraumatic stress disorder (PTSD) report difficulties accessing and describing positive memories. To understand these patterns, we examined daily-level relations of PTSD symptoms with affective, cognitive (dwelling/rumination; pushing memory out of one's mind; suppression; avoidance; distraction; thinking about something else; remembering negative or positive memories/events; negative or positive thoughts; accepting or disapproving memory; reinterpreting memory), and behavioral (using alcohol/drugs; smoking cigarettes; cravings for or seeking out cigarettes/alcohol/drugs; craving, seeking out, or consuming large amounts of food; dissociation; engaging in risky behaviors; sharing memories; interference with ongoing task; arousal) reactions to retrieving positive memories. Eighty-eight trauma survivors (Mage= 39.89 years; 59.1% female) completed 7 daily measures of PTSD and reactions to retrieving positive memories. Days with more PTSD severity were associated with higher odds of same-day suppression, avoidance, distraction, thinking about something else, smoking cigarettes, craving substances, craving, seeking out, or consuming large amounts of food, dissociation, remembering negative memories/events/thoughts, engaging in risky behaviors, interference with ongoing tasks, and arousal (ORs=1.10-1.22); and greater negative affect (β = 0.27). Supplemental lagged analyses indicated some associations between previous-day reactions to positive memory retrieval and next-day PTSD severity and vice versa. Trauma survivors with PTSD symptoms report negative and avoidance-oriented reactions to retrieving positive memories.

Abstract
BACKGROUND Research indicates that positive memories have a role in posttraumatic stress disorder's (PTSD) symptomatology and treatment. Following treatment development guidelines, a novel PTSD intervention - Processing of Positive Memories Technique (PPMT) - was developed and subsequently examined for its effects and feasibility in pilot studies. Extending this research, the proposed pilot randomized clinical trial with PPMT and Supportive Counseling (SC) arms will examine PPMT's effects on PTSD severity and biomarkers of stress systems' dysregulation (awakening salivary alpha amylase [sAA] and cortisol concentrations); examine mechanistic targets (affect) underlying PPMT's effects; and refine PPMT. We hypothesize that the PPMT arm will report greater decreases in PTSD severity and greater decreases in awakening sAA/cortisol ratio compared to the SC arm; and that improved affect (more positive affect and less negative affect) will mediate associations between intervention arm and changes in PTSD severity. METHODS We will recruit 70 individuals aged 18-65 years with PTSD. They will be randomized to 5 weekly therapy sessions of PPMT or SC, and will be assessed at baseline, weekly during treatment, 1-week post-treatment, and 3-months post-treatment. Primary outcomes are past-week PTSD severity, past-week positive and negative affect levels, and feedback data on PPMT's feasibility, format, and content. The secondary outcome is the awakening sAA/cortisol ratio. Statistical analyses include mixed-effect models and within-subjects cross-lag longitudinal mediation analyses. CONCLUSION Study results will advance knowledge of trauma interventions by examining effects and feasibility of a novel PTSD intervention, and by elucidating potential mechanisms underlying PPMT's effects.

The Effects of the Processing of Positive Memories Technique on Posttrauma Affect and Cognitions Among Survivors of Trauma: Protocol for a Daily Diary Study. JMIR Res Protoc 2024; 13:e51838.

Abstract
BACKGROUND The Processing of Positive Memories Technique (PPMT) is a promising new treatment approach for posttraumatic stress disorder (PTSD), which involves detailed narration and processing of specific positive autobiographical memories. Indeed, preliminary case-series studies have found reductions in PTSD symptoms, negative affect, and negative cognitions among survivors of trauma who have received PPMT. However, PPMT's effects have not been investigated at the daily level. In this study, we describe the protocol for a study that will examine the daily-level impacts of PPMT in a trauma-exposed, nonclinical community sample. OBJECTIVE This study uses an innovative research protocol that combines case-series design and daily diary approaches to examine changes in daily affect, daily cognitions, and daily PTSD symptoms pre- and post-PPMT. We hypothesize that at the daily level, in comparison to their own pre-PPMT levels, following the PPMT intervention, participants will report (1) a lower count of endorsed daily PTSD symptoms, (2) increases in daily positive affect and decreases in daily negative affect, (3) increases in positive affect reactivity to daily positive events, and (4) decreases in daily posttrauma cognitions. METHODS We are currently recruiting participants (target n=70) from a metroplex in the southwest United States. Following a screening survey, eligible participants complete a preintervention baseline survey, followed by 21 daily surveys in their natural environments. Then, they receive 4 PPMT sessions on a weekly basis. After the conclusion of the PPMT intervention, participants complete a postintervention outcome survey and 21 daily surveys. To compare daily affect, daily cognitions, and daily PTSD symptoms before and after PPMT, we will use the daily diary report data and conduct multilevel random intercepts and slopes linear regression models. RESULTS Data collection was initiated in March 2022 and is expected to end by June 2024. As of November 28, 2023, a total of 515 participants had consented to the study in the screening phase. No analyses will be conducted until data collection has been completed. CONCLUSIONS Study findings could clarify whether deficits in positive autobiographical memory processes may also characterize PTSD alongside deficits in traumatic memory processes. Furthermore, PPMT could be an additional therapeutic tool for clinicians to help clients reduce posttraumatic distress in their everyday lives.

Abstract
BACKGROUND AND OBJECTIVES Evidence indicates that positive memory processes play a role in the etiology and maintenance of posttraumatic stress symptoms (PTSS) and related posttrauma health indicators. To extend this research, the current pilot study examined if repeated retrieval of positive vs. neutral memories was associated with (1) less PTSS and depression severity; and (2) improved affect and cognitions (fewer posttrauma cognitions, more positively-valenced affect, less negatively-valenced affect, less negative affect interference, less anhedonia, retrieval of more positive specific memories, retrieval of fewer negative specific memories). METHODS Twenty-five trauma-exposed participants were randomly assigned to a positive or neutral memory task condition. They participated in four weekly experimental sessions facilitated by an experimenter virtually; each consecutive session was separated by 6-8 days. We conducted mixed between-within subjects ANOVAs to examine study hypotheses. RESULTS No interaction effects were significant. There were significant main effects of time on PTSS and depression severity, posttrauma cognitions, positively-valenced and negatively-valenced affect, and negative affect interference. LIMITATIONS We used self-report measures, small and non-clinical sample with limited demographic diversity, and virtual format; did not record memory narratives; and did not have a trauma memory condition. CONCLUSIONS Based on pilot data, our findings suggest that individuals who retrieve positive or neutral memories repeatedly may report less PTSS and depression severity, fewer posttrauma cognitions, and improved affect. Results provide an impetus to examine impacts of and mechanisms underlying memory interventions (beyond a sole focus on negatively-valenced memories) in trauma work.

Abstract
Complex post-traumatic stress disorder (CPTSD) has recently been recognized as an official psychiatric diagnosis in ICD-11, after years of research and advocacy in the field. It has been suggested that dissociative symptoms are a major feature of CPTSD. This scoping review aimed to summarize the existing knowledge base on the relationship between dissociation and CPTSD, and to identify relevant research gaps. We searched the two largest and most widely used academic databases (i.e., the Web of Science and Scopus databases) and the ProQuest database and identified original studies published in English relevant to our research questions, namely: (1) Would CPTSD be associated with dissociative symptoms? 2) How common are dissociative symptoms among people with CPTSD? (3) What are the correlates of dissociative symptoms among people with CPTSD? In all, 26 studies were included. We found 10 studies which reported that people with CPTSD scored significantly higher on a dissociation measure than those without CPTSD, and 11 studies reported a positive correlation between CPTSD symptoms and psychoform/somatoform dissociation scores. While very few studies reported the prevalence and correlates of dissociative symptoms among people with CPTSD, there may be a considerable subgroup of people with CPTSD who have clinically significant levels of dissociative symptoms (e.g., 28.6-76.9%). Dissociation may also be associated with other comorbidities (e.g., DSM-IV Axis II features, shame, somatic symptoms) in people with CPTSD. We recommend that more studies are needed to investigate the prevalence of dissociative symptoms among people with CPTSD and examine how these symptoms are associated with other comorbid conditions and clinical needs in this vulnerable group.

Abstract
Evidence links posttraumatic stress disorder (PTSD) symptoms to positive autobiographical memory characteristics. To extend this research, we uniquely utilized micro-longitudinal data to examine (1) the trajectory of PTSD symptom count across 30 days; and (2) if more vividness and accessibility of retrieved positive memories at the daily level predicted decreases in the trajectory of PTSD symptom count across 30 days. The current study was a secondary data analysis of a larger study. The sample included 74 women who reported physical or sexual victimization in the past 30 days by their current male partner and reported the use of alcohol and/or drugs during that time (Mage = 39.68 years; 37.80% with diagnostic PTSD; 43.2% White; 37.8% Black or African American). They completed thrice daily measures of PTSD symptoms and positive memory characteristics (vividness and accessibility) across 30 days. Results of the random effects longitudinal multilevel model indicated that, on average, the relation between PTSD symptom count and positive memory vividness was positive and statistically significant (0.19, 95% Confidence Interval [CI] [0.2, 0.35]); and the relation between PTSD symptom count and positive memory accessibility was positive and statistically significant (0.31, 95% CI [0.15, 0.47]). The relationship between PTSD symptom count and positive memory vividness/accessibility (i.e., slopes) varied significantly across participants, with a wide range of positive and negative regression coefficients. Future research needs to investigate why and how positive memory vividness and accessibility may relate to trajectories of PTSD symptoms over time, with potential clinical implications for positive memory interventions addressing PTSD.

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. 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. CONCLUSIONS Findings inform positive memory intervention targets for PTSD and provide impetus for longitudinal investigations on their inter-relations.

Abstract
OBJECTIVES Research has demonstrated links between autobiographical memory retrieval and hazardous substance use. However, limited work has examined relations between positive autobiographical memories and hazardous substance use, as well as moderating factors influencing these relations. Thus, we examined the potential moderating roles of negative and positive emotion dysregulation in the relations between count of retrieved positive memories and hazardous substance use (alcohol and drug use separately). METHODS Participants were 333 trauma-exposed students (Mage = 21.05; 85.9% women) who completed self-report measures assessing positive memory count, hazardous alcohol and drug use, negative emotion dysregulation, and positive emotion dysregulation. RESULTS Positive emotion dysregulation significantly moderated the association between positive memory count and hazardous alcohol use (b = 0.04, 95% confidence interval [CI] [0.01, 0.06], p = 0.019), as well as the association between positive memory count and hazardous drug use (b = 0.02, 95% CI [0.01, 0.03], p = 0.002). Individuals with more positive emotion dysregulation had stronger associations between increases in positive memory count and increased hazardous substance use. CONCLUSION Findings indicate that trauma-exposed individuals who retrieve more positive memories and experience difficulties regulating positive emotions report greater hazardous substance use. Positive emotion dysregulation may be an important target for memory-based interventions among trauma-exposed individuals who report hazardous substance use.

Abstract
BACKGROUND AND OBJECTIVES Avoidance, inherent to posttraumatic stress disorder (PTSD) symptomatology, is theoretically and empirically linked to the maintenance of PTSD symptom severity. While research indicates traumatized individuals avoid positive and trauma memories, several PTSD treatments focus exclusively on traumatic memories. We examined the mediating role of PTSD's avoidance in the relationship between processing positive memories and PTSD cluster severity (intrusion, mood/cognitions, arousal). METHODS Sixty-five trauma-exposed college students (Mage = 22.52; 86.10% female) were randomly assigned to 3 conditions: narrating/processing, writing/processing, or control (same task across baseline [T0] and follow-up [T1]). RESULTS Half-longitudinal mediation models indicated participation in the narrating vs. writing and control conditions predicted decreases in T1 intrusion severity via reduction in T1 avoidance severity. Similarly, participation in the narrating vs. writing and control conditions predicted decreases in T1 mood/cognitions' severity via reduction in T1 avoidance severity. Participation in the narrating vs. writing condition predicted decreases in T1 arousal severity via reduction in T1 avoidance severity. LIMITATIONS Data was obtained from an analogue small-size sample of university students. In addition, sessions were only 6-8 days apart, with the processing component of each session lasting ∼30 min. CONCLUSIONS Processing positive memories may relate to lower PTSD severity via a reduction in PTSD's avoidance, paralleling effects of processing trauma memories. Our findings support future investigations of the mechanisms underlying impacts of positive memory processing in the context of PTSD treatments.

Abstract
BACKGROUND Evidence links positive memory characteristics and hazardous alcohol use (HAU). Relevant to the current study, evidence also indicates that trauma-exposed individuals, especially those with posttraumatic stress disorder (PTSD) symptoms, report difficulties retrieving/accessing positive memories and report HAU. OBJECTIVE Considering this literature, we uniquely examined if and which positive memory characteristics were associated with HAU, and the potential mediating role of PTSD symptom severity in the examined relations. METHODS A sample of 126 trauma-exposed community participants seeking mental health treatment (Mage=34.97 years) completed measures of HAU (Alcohol Use Disorders Identification Test), positive memory characteristics (Memory Experiences Questionnaire-Short Form [MEQ-SF]), and PTSD severity (PTSD Checklist for DSM-5). We conducted 8 hierarchical multiple regressions; Step 1 examined effects of gender and Step 2 added a single MEQ-SF dimension (specificity, valence, emotional intensity, sensory details, vividness, accessibility, coherence, sharing). RESULTS In Steps 1 (β=.27) and 2 (βs from .27-.28), gender was associated with HAU. In Step 2, positive memory characteristics of specificity (β=.17), sensory details (β=.17), sharing (β=.23), and valence (β=-.19) were associated with greater HAU. PTSD severity mediated relations between sensory details (β=.09, p=.048), emotional intensity (β=.12, p=.011), and sharing (β=.09, p=.036), and the extent of HAU. CONCLUSIONS AND IMPLICATIONS Results that specificity, greater sharing, more sensory details, and higher negative valence of positive memories were associated with greater HAU offer potential points of intervention.
