Expressive inhibition in response to stress: implications for emotional processing following trauma

A latent profile analysis of emotional expression among patients with unintentional injuries

BACKGROUND

Emotional expression has been suggested to affect the well-being of individuals with unintentional injuries. However, few studies have investigated it as a heterogeneous phenomenon. The purpose of this study was to characterize the patterns of emotional expression among patients with unintentional injuries using latent profile analysis, and to examine the relationship among these latent profiles and cognitive processing, posttraumatic growth, and posttraumatic stress disorder.

METHODS

A cross-sectional study was carried out at two general hospitals in Wenzhou, China. In total, 352 patients with unintentional injuries completed the socio-demographic questionnaire, Berkeley Expressivity Questionnaire, Ambivalence Over Emotional Expression Questionnaire, Event-Related Rumination Inventory, the Posttraumatic Growth Inventory, and PTSD Checklist-Civilian Version.  RESULTS: Three unique profiles were identified: high emotional expressivity (n = 238, 67.6%), moderate emotional expressivity (n = 45, 12.8%), and low emotional expressivity (n = 69, 19.6%). The ANOVA and chi-square tests demonstrated significant differences among the three groups concerning deliberate rumination and posttraumatic growth. Multinomial logistic regression analysis indicated that monthly income and time since injury significantly predicted profile membership.

CONCLUSIONS

Most patients showed high emotional expressivity after an unintentional injury. Emotional expression profiles were associated with deliberate rumination and posttraumatic growth. Emotional expression interventions tailored for different profiles are warranted after an unintentional injury.

Written Emotional Disclosure Can Promote Athletes' Mental Health and Performance Readiness During the COVID-19 Pandemic

The widespread effects of the coronavirus disease 2019 (COVID-19) pandemic have negatively impacted upon many athletes’ mental health and increased reports of depression as well as symptoms of anxiety. Disruptions to training and competition schedules can induce athletes’ emotional distress, while concomitant government-imposed restrictions (e.g., social isolation, quarantines) reduce the availability of athletes’ social and emotional support. Written Emotional Disclosure (WED) has been used extensively in a variety of settings with diverse populations as a means to promote emotional processing. The expressive writing protocol has been used to a limited extent in the context of sport and predominantly in support of athletes’ emotional processing during injury rehabilitation. We propose that WED offers an evidence-based treatment that can promote athletes’ mental health and support their return to competition. Research exploring the efficacy of the expressive writing protocol highlights a number of theoretical models underpinning the positive effects of WED; we outline how each of these potential mechanisms can address the multidimensional complexity of the challenging circumstances arising from the COVID-19 pandemic (e.g., loss of earnings, returning to training and competition). Considerations and strategies for using WED to support athletes during the COVID-19 pandemic are presented.

An Extension of the Perseverative Cognition Hypothesis to Posttraumatic Stress Disorder Symptomatology: Cardiovascular Recovery in Relation to Posttraumatic Stress Disorder Severity and Cognitive Appraisals of Stress

Beyond the construct of cardiovascular reactivity, the measurement of cardiovascular recovery from stress represents an important index of exaggerated physiological arousal and disease risk. Cardiovascular recovery in posttraumatic stress disorder (PTSD) has not received adequate attention. The present study examined whether cardiovascular recovery following an oral speaking stressor was associated with the severity of PTSD symptoms, and whether cognitive stress appraisals of threat and challenge were significantly associated with PTSD severity and recovery. The sample consisted of 50 trauma-exposed civilian women ranging from 19 to 49 years of age (M = 30.9, SD = 7.8). The PTSD severity indices were quantified based on structured interview. Cardiovascular recovery was assessed at two posttask time points as percentage return to baseline; the recovery measures consisted of impedance cardiography-derived cardiac output (CO) and total peripheral resistance (TPR), heart rate and blood pressure. Total PTSD severity was associated with less CO recovery, r = -.39, p = .006; this effect was similar across PTSD symptom categories, with significant correlations ranging from r = -.30 to r = -.44. However, only PTSD severity in the avoidance cluster was associated with less TPR recovery, r = -.29, p = .047. Total PTSD severity was associated with greater threat appraisal, r = .30, p = .035, and greater threat appraisal was associated with less CO recovery, r = -.33, p = .019. Results partially support the theory that greater PTSD severity and cognitive appraisals of threat contribute to less cardiovascular recovery when confronted with a stress-inducing situation.

A prospective examination of risk factors in the development of intrusions following a trauma analog

Several factors have been linked to the severity of posttraumatic distress, although retrospective designs in much of the literature limit conclusions regarding the temporal relation between risk factors and corresponding symptoms. To address these concerns, the current project employed an analog trauma paradigm to assess the impact of background characteristics, stress response, and post-stressor affect regulation on subjective distress and intrusive memories experienced during the subsequent processing of emotional stimuli. University students (N = 184; 56% female, 42% White/Non-Hispanic) were shown graphic scenes of a televised suicide. Physiological activation was recorded during exposure with emotion ratings collected following the film. Participants then viewed a sadness- or humor-eliciting prime under instructions to inhibit or naturally express emotion. Intrusions experienced during the priming film and residual distress at study's conclusion were rated prior to debriefing. Hierarchical regression identified reductions in emotional valence as a robust predictor of intrusions and distress. Sympathetic activation and exposure to the sadness prime were associated with intrusion frequency, whereas attenuated parasympathetic response predicted intrusion intensity. Expressive inhibition demonstrated a unique association with residual distress. Results suggest peritraumatic processes and post-exposure factors may hold more prominent relations with immediate trauma-related distress as compared to pre-existing survivor characteristics.

Fidelity to the Cognitive Processing Therapy Protocol: Evaluation of Critical Elements

The contributions of individual therapy elements to the overall efficacy of evidence-based practices for the treatment of posttraumatic stress disorder (PTSD) are not well-understood. This study first examined the extent to which theoretically important treatment components of Cognitive Processing Therapy (CPT; i.e., skill in Socratic questioning; prioritizing assimilation; attention to practice assignments; emphasis on expression of natural affect) were successfully administered across the course of therapy for 68 PTSD-positive survivors of interpersonal trauma. Therapist fidelity in the administration of these four elements was evaluated in 533 taped CPT sessions of study participants included in one of two randomized controlled CPT treatment trials. Second, we examined therapist fidelity to these components as a predictor of session-to-session PTSD and depression symptom change. Third, follow-up analyses examined the influence of high therapist competence for these four components across an entire course of therapy on symptom change from pre- to posttreatment. Results showed consistently high adherence and more variable competence for these four treatment components. There were no significant effects of therapist fidelity on session-to-session symptom change. However, results showed that overall high therapist competence for "skill in Socratic questioning" and "prioritizing assimilation before overaccommodation" were related to greater client improvement in PTSD severity, but "attention to practice assignments" and "emphasis on expression of natural affect" were not. Overall competence ratings for the four components were not significantly associated with improvement in depressive symptoms. Findings contribute to increased understanding of the relationship between the key treatment components of CPT and symptom change.
