How Distress Tolerance Mediates the Relationship Between Posttraumatic Stress Disorder and the Interpersonal Theory of Suicide Constructs in a U.S. Military Sample

Prevalence and risk factors of PTSD symptoms: a 3-month follow-up study

Background

During the peak of the epidemic, hospitalized patients frequently encountered significant health risks and potentially life-threatening circumstances, including uncertainty regarding treatment and the potential for complications.

Objective

The present study aimed to explore the prevalence of post-traumatic stress disorder (PTSD) symptoms among hospitalized patients 3 months after discharge during the first peak of the epidemic, and the association of PTSD with disease-related characteristics.

Design

A single-center and full-sample follow-up study was conducted on COVID-19 patients from the Optical Valley Branch of Maternal and Child Hospital of Hubei Province, Wuhan, China. Data were collected during their hospitalization and 3 months after discharge.

Methods

PTSD symptoms were evaluated by primary care post-traumatic stress disorder (PC-PTSD), a total score of 3 or above was considered as clinically significant PTSD symptoms. Demographic and disease-related characteristics were collected to identify related associations with PTSD symptoms.

Results

A total of 903 patients completed the follow-up survey, yielding a response rate of 63.5%. A total of 212 (23.5%) of the patients were positive in PC-PTSD screening. Univariate regression analysis identified several factors correlated with PTSD symptoms, including female gender, younger age, a lower body mass index (BMI), preexisting sleep problems, bereavement due to COVID-19, a severe clinical diagnosis, the presence of three or more clinical symptoms at disease onset, and residual respiratory symptoms after discharge. Notably, in the multivariate regression analysis, experiencing three or more clinical symptoms at onset emerged as a robust predictor of PTSD symptoms (OR = 2.09, 95% CI: 1.48-2.95). An intriguing finding was that patients who underwent radiological assessment post-discharge reported a higher incidence of PTSD symptoms, whereas those who underwent re-testing for IgG or IgM antibodies exhibited a lower prevalence of PTSD symptoms.

Conclusion

Three months post-recovery, PTSD symptoms prevalence among COVID-19 patients was 23.5%. Those with three or more clinical symptoms at onset or residual respiratory symptoms post-discharge showed higher risk. These findings highlighted the long-term effect of COVID-19 on mental health, urging enhanced attention and interventions for survivors.

Emotional Disorders, Distress Tolerance and Suicide Risk: A Mediation Model

Background: Suicide has been linked to psychopathology, particularly emotional disorders. This study seeks to investigate the mediating role of distress tolerance in the relationship between emotional symptoms and suicide risk. Method: The sample included 1014 adults (33.82% male; M = 33.0, SD = 15.15). Four mediation analyses were performed, controlling for sex, for depressive, anxious, somatizing and obsessive symptoms measured with the Brief Symptom Checklist as the independent variable, distress tolerance, measured with the Distress Tolerance Scale as the mediating variable, and the risk of making a suicide attempt, measured with Risk of Suicide, as the dependent variable. Results: Distress tolerance partially mediated the relationship between emotional symptoms and suicide risk, with Appraisal and Absorption scales positively mediating, and Tolerance negatively mediating. Conclusions: Tolerance of distress plays a role in risk of suicide attempts. Distress tolerance needs to be addressed as a key transdiagnostic factor in reducing suicidal risk.

Psychiatric and non-psychiatric population vulnerabilities in time of a crisis: the unsuspected aggression factor

OBJECTIVES

In March 2020, France faced a health crisis due to the COVID-19 outbreak that, like previous infectious disease crises, involved high psychological and emotional stress, a series of factors that influenced the ongoing mental health crisis.

METHODS

We recruited 384 respondents to complete an online questionnaire during the second month of isolation: 176 psychotherapy recipients (68 were currently attending psychiatric care) and 208 healthy controls. We measured demographic characteristics, impulsivity, aggression, hopelessness, suicidal risk, and the global level of anxiety and depression in order to estimate potential discrepancies in clinical measures across these populations.

RESULTS

Our results indicate that the group currently undergoing psychiatric care was prone to loneliness and social isolation. Regarding clinical and nonclinical population, there were differences in suicidal risk, depression, anxiety, and hopelessness but mainly in aggression. Regression analysis also demonstrated that aggression surprisingly influenced anxiety levels. Patients undergoing therapy compared with patients who were not displayed differences only in suicidal risk, anxiety, and hopelessness, with those undergoing therapy having higher scores. The outpatient group undergoing therapy had a significantly lower level of impulsivity. Moreover, the regression to predict anxiety and depression levels from correlated factors highlighted the potentially heightened role of aggression in predicting anxiety in the clinical group.

CONCLUSION

New research into stress reactions should assess other clinical signals, such as aggression, and examine preventive mental health interventions in times of crisis.

Distress Tolerance and Emotion Regulation as Potential Mediators Between Secondary Traumatic Stress and Maladaptive Coping

The extant literature has illustrated that protective service workers experience negative repercussions associated with their job (including the development of secondary traumatic stress; STS) and may utilize maladaptive coping mechanisms. Developing an improved understanding of factors that might explain the relationship between STS and the utilization of maladaptive coping mechanisms is warranted. This study sought to examine emotion regulation and distress tolerance as potential mediators between STS and the utilization of maladaptive coping mechanisms. Participants were 152 elder protective service workers and 105 child protective service workers who completed an online survey of self-report measures of emotion regulation, distress tolerance, STS, and coping behaviors. A parallel multiple mediator model was analyzed using structural equation modeling (SEM) to examine the hypothesis that distress tolerance and emotion regulation would mediate the relationship between STS and the utilization of maladaptive coping. Our hypothesis was partially supported as the effect of STS on maladaptive coping was mediated by emotion regulation but not by distress tolerance. The results from this study have both prevention and intervention implications. From a prevention perspective, efforts could be directed at teaching emotion regulation skills to those at risk for developing STS as a mechanism for decreasing the probability of denial, substance use, behavioral disengagement, and self-blame that may occur as a consequence of STS. From an intervention perspective, some of the negative sequelae of exposure to STS may be averted by teaching EPS and CPS workers who present with STS symptoms, emotion regulation skills.

Distress tolerance and posttraumatic stress disorder: a systematic review and meta-analysis

The association between distress tolerance (DT) and posttraumatic stress disorder (PTSD) is well established. This study aimed to provide an account of the magnitude of this effect across available studies. From the 2,212 records yielded by the initial search, 56 studies comprised 12,672 participants (M_age = 29.96, SD = 12.05; 44.94% women) were included in the investigation upon a priori criteria. Results demonstrated consistent negative associations between DT and PTSD symptoms, such that lower DT was associated with higher PTSD symptom severity and vice versa; the effect size (ES) was relatively small in magnitude (r = -0.335, 95% CI [-0.379, -0.289]). Moreover, ESs for the DT-PTSD association were significantly greater for studies which examined self-reported DT compared to those that examined behavioral DT. The number of traumatic event types experienced (trauma load) was the most consistent moderator of the DT and PTSD association. The clinical implications of the role of DT in PTSD are discussed.

The protective effects of grit on suicidal ideation in individuals with trauma and symptoms of posttraumatic stress

OBJECTIVE

It is important to understand factors that moderate the likelihood of developing suicidal thoughts following traumatic exposure and posttraumatic stress symptoms.

METHOD

In this cross-sectional study, a moderated atemporal mediation analysis was conducted in a sample of 709 college students (71% female, M _age  = 19.90 years, 67% Caucasian) to test the associations between trauma, posttraumatic stress disorder (PTSD) symptoms, and suicidal ideation, with grit entered as a moderator of all paths in the equation.

RESULTS

PTSD symptoms mediated the association between trauma and suicidal ideation. Grit moderated the direct pathway from PTSD symptoms to suicidal ideation.

CONCLUSIONS

Grit and other constructs of resiliency may inform strength-focused interventions to remediate the impact of trauma and posttraumatic stress symptoms and potentially reduce suicidal thoughts and risk for suicide.
