The memory-experience gap for PTSD symptoms: The correspondence between experience sampling and past month retrospective reports of traumatic stress symptoms

Concordance of Posttraumatic Stress Disorder Symptoms Assessed via Retrospective Report Versus Experience Sampling Methods in Community Women Experiencing Intimate Partner Violence

Posttraumatic stress disorder (PTSD) is one of the most prominent negative health consequences that women experiencing intimate partner violence (IPV) may develop. However, research on PTSD among women experiencing IPV has largely relied on retrospective reporting methods, which are vulnerable to bias and may consequently misrepresent PTSD symptoms. This study evaluated the concordance between PTSD symptoms assessed via retrospective self-report and experience sampling methods (ESM), which involve repeated within-day sampling of experiences in near real-time and in natural environments. Community women (N = 134) experiencing IPV (Mage = 40.7, 30.4% Black) responded to ESM surveys three times a day for 30 days and then completed a follow-up interview. Retrospective self-report of PTSD symptoms, which were assessed during the follow-up interview, were compared to ESM reports of PTSD symptoms. Retrospective reports of PTSD symptoms were significantly different from PTSD symptoms reported during the ESM period, but most closely resembled peak PTSD symptoms. Notably, retrospective reports of PTSD symptoms were significantly different, with a very large effect size, from average PTSD symptoms reported during the ESM period. Discordance scores were significantly negatively associated with the number of days on which any IPV occurred, suggesting that as the frequency of IPV experiences increased, differences between retrospective PTSD symptoms and each ESM symptom pattern decreased. This study provides an important contribution to the literature by highlighting meaningful differences in PTSD symptoms assessed via retrospective self-report versus ESM and the role of IPV context. Findings emphasize the importance of utilizing ESM in PTSD research with women experiencing IPV.

Beyond the mean: examining associations between intraindividual variability in posttraumatic stress disorder symptoms and posttrauma reckless behaviors

BACKGROUND/OBJECTIVES

Posttrauma reckless behaviors have been linked to the onset and exacerbation of posttraumatic stress disorder (PTSD) symptoms. However, PTSD symptoms fluctuate across time, triggered by environmental stimuli in daily life, referred to as (intraindividual) variability in PTSD symptoms.

DESIGN

We utilized experience sampling methods to investigate associations between engagement in posttrauma reckless behaviors and variability in PTSD symptoms and the moderating role of emotion dysregulation in this association.

METHODS

Data from 166 trauma-exposed university students (Mage = 21.43 ± 5.07, 85.4% women) were collected between January 2019 to August 2020. Participants completed baseline and follow-up surveys to assess engagement in posttrauma reckless behaviors and daily surveys (10-days) to assess variability in PTSD symptoms. Results. Analyzes indicated greater baseline engagement in posttrauma reckless behaviors was associated with greater 10-day variability in PTSD symptoms (β = 0.23, p = .031), and baseline emotion dysregulation moderated this association (β = -0.33, p = .003). Additionally, greater 10-day variability in PTSD symptoms was associated with greater follow-up engagement in posttrauma reckless behaviors (β = 0.14, p = .045).

CONCLUSIONS

Findings substantiate the interplay between engagement in posttrauma reckless behaviors and daily fluctuations in PTSD symptoms and support therapeutically targeting both engagement in posttrauma reckless behaviors and emotion dysregulation to impact PTSD symptoms.

The Effects of the Processing of Positive Memories Technique on Posttrauma Affect and Cognitions Among Survivors of Trauma: Protocol for a Daily Diary Study

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.
