Understanding the role of dysfunctional post-trauma cognitions in the co-occurrence of Posttraumatic Stress Disorder and Generalized Anxiety Disorder: Two trauma samples

From identity-based distress to thinking "I am better off being dead:" Minority stress, posttraumatic cognitions, and suicidal ideation

BACKGROUND

Suicidal ideation (SI) disproportionately impacts individuals with minoritized race/ethnicity, gender, and sexual orientation. Minority stress - i.e., traumatic, insidious distress that results from acts of discrimination - may lead to the formation of posttraumatic cognitions that may generalize to suicidal ideation, elevating SI risk in minoritized populations. The current study aimed to test this potential relationship by examining whether minority stress and posttraumatic cognitions accounted for the association between discrimination and SI.

METHODS

Series of structural equation models, including multigroup confirmatory factor analyses conducted to test invariance of latent constructs, were estimated on cross-sectional data collected from minoritized young adults (n = 337).

RESULTS

Results supported the hypothesized model: experience of discrimination indirectly associated with SI via correlations shared between minority stress and posttraumatic cognitions. Experiences of discrimination lacked a significant correlation with SI while accounting for minority stress and posttraumatic cognition variance. Invariance testing conducted to account for applicability of the model across race, ethnicity, sexual orientation, and plurality of minoritized identities all demonstrated that the model was applicable across these identity dimensions.

LIMITATIONS

Granular inspection of identity dimensions was infeasible due to sample size and causal inferences cannot be drawn given cross-sectional nature of the data used.

CONCLUSIONS

Posttraumatic cognitions within the context of discrimination may be effective treatment targets for minoritized individuals who present with minority stress and SI. Future studies should aim to replicate such findings longitudinally to infer temporality.

Sexual Assault History May Moderate Posttraumatic Cognition and Posttraumatic Stress Among Trauma-Exposed Sexual Minority Women

Sexual minority women (SMW) are highly vulnerable to trauma exposure and posttraumatic stress disorder (PTSD) symptoms following trauma exposure. Negative posttraumatic cognitions (i.e., negative cognitions about self, world, and self-blame following trauma exposure) are hypothesized to exacerbate and maintain the relationship between trauma exposure and PTSD symptoms. Posttraumatic cognitions are particularly important to examine in relation to PTSD symptoms among trauma-exposed SMW given their elevated risk for trauma exposure and PTSD. It is also important to understand whether the strength of this relationship differs as a function of trauma type to elucidate potentially differential pathways for risk by trauma type in this population. The current study explored whether trauma type (sexual assault vs. nonsexual trauma) moderated the relationship between negative posttraumatic cognitions and PTSD symptom severity among a sample of trauma-exposed SMW. Participants were SMW (n = 516) users of an online survey platform, Prolific. Data were collected via 20-minute online survey. Results indicated that trauma type moderated the relationship between negative posttraumatic cognitions and PTSD symptom severity, such that the relationship was stronger among those who had experienced at least one sexual assault in their lifetime. Results suggest that negative posttraumatic cognitions may be more strongly related to PTSD symptom severity among SMW who have experienced at least one sexual assault. Notably, this difference was in magnitude only, as the posttraumatic cognition-PTSD symptom relationship remained significant among nonsexual trauma survivors. Negative posttraumatic cognitions may be an especially relevant treatment target among SMW survivors of sexual assault.

A path model of associations between war-related exposure to trauma, nightmares, fear, insomnia, and posttraumatic stress among Ukrainian students during the Russian invasion

The present study examined the associations between war-related exposure, nightmares, fear, insomnia, and PTSD symptoms among university students from Western Ukraine. An online cross-sectional study was performed among 1,072 university students (80% of whom were women) during the war. Eight questions were developed to assess exposure to war, and seven items were designed regarding nightmares of war. War-related PTSD symptoms were assessed using an abbreviated six-item PTSD checklist (PCL-6), insomnia was measured using the Athens Insomnia Scale (AIS), and to examine fear of war, the Fear of COVID-19 Scale (FoCV-19S) was adopted. Positive correlations were found between exposure to war, nightmares of war, fear of war, insomnia, and war-related PTSD. The path model using structural equation modelling (SEM) analysis showed that the chain mediation partially explains the relationship between war exposure and war-related PTSD symptoms via nightmares of war, fear of war, and insomnia among university students during the Russian invasion of Ukraine. Women scored significantly higher than men in fear of war and symptoms of insomnia and PTSD, but the path model was invariant across genders. Young adults require treatment focused primarily on nightmares, insomnia, and fear of war to prevent PTSD symptoms.

Validation of the PCL-5, PHQ-9, and GAD-7 in a Sample of Veterans

OBJECTIVE

Veterans can present at nongovernment (Department of Defense, Department of Veterans Affairs) mental health agencies with complex symptom constellations that frequently include posttraumatic stress disorder, depression, and generalized anxiety. To date, no veteran study has validated these measures on a treatment-seeking sample of veterans outside the DoD and VA.

METHODS

We used a treatment-seeking sample of veterans ( N = 493) to validate measures that assess these constructs (PTSD Checklist 5, Patient Health Questionnaire-9, and Generalized Anxiety Disorder-7).

RESULTS

The seven-factor posttraumatic stress disorder hybrid configuration was the best fit. The best fitting model of the depression measure was a two-factor structure, cognitive-affective, and somatic depression. The measure of generalized anxiety was a unidimensional model.

LIMITATIONS

Follow-up studies should validate these measures on nontreatment-seeking discharged veterans.

CONCLUSIONS

We interpret these findings within the veteran scholarship and explore clinical implications for providers.

Prevalence of post-traumatic stress disorder in the United States: a systematic literature review

OBJECTIVE

This study synthesized evidence regarding the prevalence of post-traumatic stress disorder (PTSD) in the United States (US).

METHODS

A systematic literature review (SLR) identified recently published (2015-2019) observational studies of PTSD prevalence in the US via the MEDLINE, EMBASE, and PsycINFO databases. Eligible studies' most recent data were collected no earlier than 2013. Data elements extracted included study design, sample size, location, data source/year(s), study population(s), traumatic event type, prevalance estimates with corresponding look-back periods, and clinical metrics.

RESULTS

Data from 38 identified articles were categorized by population, diagnostic criteria, and lookback period. Among civilians, point prevalence ranged from 8.0% to 56.7%, 1-year prevalence from 2.3% to 9.1%, and lifetime prevalence from 3.4% to 26.9%. In military populations, point prevalence ranged from 1.2% to 87.5%, 1-year prevalence from 6.7% to 50.2%, and lifetime prevalence from 7.7% to 17.0%. Within these ranges, several estimates were derived from relatively high quality data; these articles are highlighted in the review. Prevalence was elevated in subpopulations including emergency responders, refugees, American Indian/Alaska Natives, individuals with heavy substance use, individuals with a past suicide attempt, trans-masculine individuals, and women with prior military sexual trauma. Female sex, lower income, younger age, and behavioral health conditions were identified as risk factors for PTSD.

CONCLUSIONS

PTSD prevalence estimates varied widely, partly due to different study designs, populations, and methodologies, and recent nationally representative estimates were lacking. Efforts to increase PTSD screening and improve disease awareness may allow for a better detection and management of PTSD.

Protective Factors Associated With Fewer Generalized Anxiety Disorder Symptoms Among Women Exposed to Intimate Partner Violence

Generalized anxiety disorder (GAD) has received minimal empirical attention in the context of intimate partner violence (IPV). Furthermore, factors related to lower levels of GAD symptoms in this population have received limited focus. This study evaluated the protective role of four forms of support, spiritual, family, friend, and community, in predicting levels of generalized anxiety among women who have experienced recent IPV. Participants included 116 women who were recruited from local agencies serving IPV-exposed individuals. Participants completed measures of IPV, GAD, stressful life events, spiritual support, social support, and community support during a 1-hr interview. Findings from a hierarchical multiple regression analysis indicated that after accounting for age, income, mental health service utilization, stressful life events, and severity of IPV, lower GAD symptoms were only associated with higher spiritual support (β = -0.20, p = .02) and community support (β = -0.25, p = .01), not friend or family support, F(9, 114) = 5.10; p < .001; R² = .30. These findings indicate that alternative sources of support (i.e., spiritual and community) may be more accessible for IPV-exposed women, contributing to their association with reduced GAD symptomatology. The current study highlights the potential for spiritual and community support to serve a beneficial role above and beyond standard social support proffered by friends and family on symptoms of GAD. Results reinforce the examination of a broad range of multiple supports among women experiencing IPV. This thorough examination of different support systems may provide further insight into novel resources that can be strengthened among IPV-exposed populations.

The role of negative cognitions in co-occurring posttraumatic stress disorder and depression: Examination of interpersonal and noninterpersonal trauma survivors

OBJECTIVE

To examine negative cognitions underlying both posttraumatic stress disorder (PTSD) and depression following trauma.

METHOD

A mixed-gender motor vehicle accident (N = 297, M_age  = 43.49 years) sample and a female intimate partner violence (N = 242, M_age  = 36.95 years) sample was cross-sectionally studied at research clinics of two universities.

RESULTS

When diagnostic groups (PTSD+/-, depression+/-) were studied, no significant interactions were noted for any of the three forms of negative cognitions (negative thoughts about the self, negative thoughts about the world, and self-blame) in either sample. When continuous ratings of PTSD and depression were studied, the results showed that negative thoughts about the self were linked to both PTSD and depression.

CONCLUSION

Findings suggest that it may be beneficial to target negative thoughts about the self when treating PTSD and depression together.

Latent profiles of the comorbidity of the symptoms for posttraumatic stress disorder and generalized anxiety disorder among children and adolescents who are susceptible to COVID-19

The present study aims to examine the comorbidity patterns of the symptoms (intrusion and avoidance) for posttraumatic stress disorder (PTSD) and generalized anxiety disorder (GAD) and the role of perceived threat and courtesy stigma in distinguishing specific patterns of the symptoms for PTSD and GAD among children and adolescents who are susceptible to coronavirus disease 2019 (COVID-19) in Hubei, China. A total of 1172 (683 female and 489 male) children and adolescents aged 8-18 years were involved in completing the measurements of PTSD, GAD, perceived threat of COVID-19, and COVID-19-related courtesy stigma. The Latent Profile Analysis identified the three profiles of the symptoms for PTSD and GAD which were labeled as Moderate PTSD, Mild Comorbidity, and Severe Comorbidity. The scores of the symptoms for PTSD, GAD, perceived threat, and stigma were different among the three profiles. The risk factors (i.e., perceived threat and stigma) that are related to comorbidity patterns were examined through a three-step method. The possibility of entry into the Severe Comorbidity Profile increased with increasing perceived threat and stigma. The mental health care interventions for children and adolescents who are susceptible to COVID-19 can be developed to reduce perceived threat and stigma.

Weekly Changes in Blame and PTSD Among Active-Duty Military Personnel Receiving Cognitive Processing Therapy

Both negative posttraumatic cognitions and posttraumatic stress disorder (PTSD) symptoms decrease over the course of cognitive-behavior therapy for PTSD; however, further research is needed to determine whether cognitive change precedes and predicts symptom change. The present study examined whether weekly changes in blame predicted subsequent changes in PTSD symptoms over the course of cognitive processing therapy (CPT). Participants consisted of 321 active duty U.S. Army soldiers with PTSD who received CPT in one of two clinical trials. Symptoms of PTSD and blame were assessed at baseline and weekly throughout treatment. Bivariate latent difference score modeling was used to examine temporal sequential dependencies between the constructs. Results indicated that changes in self-blame and PTSD symptoms were dynamically linked: When examining cross-construct predictors, changes in PTSD symptoms were predicted by prior changes in self-blame, but changes in self-blame were also predicted by both prior levels of and prior changes in PTSD. Changes in other-blame were predicted by prior levels of PTSD, but changes in other-blame did not predict changes in PTSD symptoms. Findings highlight the dynamic relationship between self-blame and PTSD symptoms during treatment in this active military sample.

The Association Between Posttraumatic Negative Self-Conscious Cognitions and Emotions and Maladaptive Behaviors: Does Time Since Trauma Exposure Matter?

Negative beliefs about the self, self-blame, guilt, and shame have been consistently linked to emotional problems, such as posttraumatic stress disorder and depression, following trauma exposure. To expand understanding of the potential role of negative self-conscious cognitions and emotions in other forms of posttrauma maladjustments, such as maladaptive behaviors, the current study examined the associations between these cognitions and emotions with dissociation, alcohol use, and avoidant problem-solving. As a secondary goal, the influence of time since trauma exposure was considered given recent data suggesting that some posttraumatic responses require lengthier time following trauma to become salient. Multiple-group analysis was conducted in two groups of female survivors of intimate partner violence (IPV): women whose IPV experiences occurred within 3 months prior to assessment (early posttrauma phase [EPP]; n = 67) and those whose experiences occurred 12 months or more prior to assessment (chronic posttrauma phase [CPP]; n = 145). The results suggested model invariance. Posttraumatic negative self-conscious cognitions and emotions were significantly correlated with dissociation (EPP group: β = .61, p < .001 and CPP group: β = .48, p < .001), alcohol use (EPP group: β = .31, p = .014 and CPP group: β = .30, p < .001), and avoidant problem-solving (EPP group: β = .58, p < .001 and CPP group: β = .56, p < .001). The findings highlight the importance of negative self-conscious cognitions and emotions in posttrauma maladjustment and support intervening in these domains shortly after trauma exposure.

Religiosity and the concept of god moderate the relationship between the type of trauma, posttraumatic cognitions, and mental health

The aim of the study was to examine the role of religiosity as a moderator in the relationships between trauma, posttraumatic cognitions, and mental health. A one-dimensional measure of religiosity and a multidimensional "concept of god" measure were used; sexual and nonsexual traumatic events were assessed and posttraumatic cognitions related to either sexual or nonsexual trauma were taken into account. A total of 337 females from Poland participated in the cross-sectional study. It was predicted that the relationships between sexual trauma and mental health would be stronger in religious individuals - this hypothesis was supported in the case of negative mental health (PTSD, z = -1.88, p = .003). No significant effects were found for nonsexual trauma; overall, highly religious individuals who had recently experienced trauma showed higher levels of satisfaction with life than nonreligious participants. As for the posttraumatic cognitions, one-dimensional religiosity was not a significant factor, but the self-blame cognitions and the concept of severe god were positively linked. In the case of sexual trauma, this effect was significant among nonreligious individuals. Moreover, the relationship between self-blame and PTSD was stronger in individuals who had the severe god concept. The current study was conducted in a religious society, where the majority of the population is raised as Roman Catholics. It has been demonstrated that religiosity is an important factor in the processing of trauma. This does not apply to religious individuals only: the concept of god was also a significant factor in nonreligious women.

Driving cognitions, rumination, and posttraumatic stress disorder in road traffic accidents survivors

This study evaluated the relationships between driving cognitions (i.e., panic-related cognitions, accident-related cognitions, and social-related cognitions), rumination, and posttraumatic stress disorder (PTSD) symptoms in a sample of road traffic accidents (RTAs) survivors. We also investigated the indirect effect of driving cognitions on PTSD symptoms through rumination. The sample included 633 drivers (62% were men; Mage = 36.09; standard deviation [SD] = 11.42 years). The participants completed scales measuring driving cognitions, rumination, and PTSD symptoms, as well as providing their demographic information. The results showed that all three types of driving cognitions assessed in the present study and rumination were significantly positively associated with PTSD symptoms. Furthermore, rumination mediated the relation between social-related cognitions and PTSD symptoms. The implications for PTSD treatment and future research are discussed.

Validation of the polish version of the posttraumatic cognitions inventory

The paper presents the Polish version of the Posttraumatic Cognitions Inventory developed by Foa and colleagues Psychological Assessment, 11(3), 303–314 (Foa et al., 1999). The scale measures three types of cognitions that are typically associated with traumatic experiences: negative cognitions about the self, negative cognitions about the world, and self-blame. The scale was translated to Polish using a forward – backward translation method; it was administered to a group of adult Polish women from the general population. A total of 337 individuals participated in the project. Traumatic experiences of sexual and non-sexual type were assessed and separate analyses were conducted for cognitions related to trauma of non-sexual and sexual nature. Moreover, the cumulative trauma and the severity of symptoms of the posttraumatic stress disorder were measured. Reliability of all scales was proven to be very good, with Cronbach-α for all scales above.80. There was a positive correlation between all three types of posttraumatic cognitions and (1) severity of the PTSD symptoms, (2) number of different traumatic events. The results of the current study provided partial support for the three factor structure of the tool: three factors emerged in exploratory factor analyses, but the correlations between the subscales were very high. Also, confirmatory factor analyses did not support the original solution. Overall, the Polish version of the PTCI has good psychometric properties and can be used in research, considerable evidence to support the three factor solution was also found.

Injury and Psychiatric Disorder in Low-Income Women Experiencing Bidirectional Intimate Partner Violence

This study compared severity of physical violence, intimate partner violence (IPV)-related injury, and lifetime diagnoses of psychiatric disorders among women in relationships with bidirectional, unidirectional, or no IPV. The sample includes 763 low-income women from community-based family planning clinics. Results showed that women in relationships with bidirectional IPV were more likely to experience severe physical violence and severe IPV-related injury compared to women in the unidirectional IPV category. These women were also more likely to be diagnosed with drug abuse and depression than women in relationships without IPV. Similarly, women in the bidirectional IPV category were more likely to be diagnosed with drug abuse when compared to women in the victim-only unidirectional IPV category. Recommendations for health-care providers are discussed.

Prevalence of posttraumatic stress disorder among road traffic accident survivors: A PRISMA-compliant meta-analysis

BACKGROUND

Involvement in road traffic accidents (RTAs) may put individuals at increased risk for a wide range of psychiatric disorders, among which posttraumatic stress disorder (PTSD) presents a public health issue. However, a great disparity was observed among studies exploring the prevalence of PTSD among RTA survivors. This meta-analysis aimed to explore the pooled prevalence of PTSD among RTA survivors.

METHODS

Electronic databases of PubMed, Embase, Web of Science, PsycARTICLES, PsycINFO, and CINAHL were searched to identify relevant studies. Study selection and data extraction were conducted independently by 2 investigators, and a meta-analysis was performed to synthesize the data. Heterogeneity among studies was evaluated using the Cochran Q test and quantified using the I statistic. Subgroup analyses were performed to identify the source of the heterogeneity. The possibility of publication bias was assessed using Egger linear test.

RESULTS

Fifteen eligible studies containing 6804 RTA survivors were identified in this meta-analysis, of which 1489 were identified with PTSD. The pooled prevalence of PTSD among RTA survivors was 22.25% (95% confidence interval: 16.71%-28.33%). A high degree of heterogeneity was observed across studies (I = 97.1%, P < .001), with reported PTSD prevalence ranging from 6.3% to 58.3%. Subgroup analyses found that the prevalence of PTSD among RTA survivors varied significantly across studies in relation to the instrument used to assess PTSD, country, race, gender, and education level (P < .05).

CONCLUSION

The high pooled prevalence of PTSD among RTA survivors found in this study significantly underscores the need for providing timely and effective intervention strategies for RTA survivors.

DSM-5-based latent PTSD models: Assessing structural relations with GAD in Filipino post-relocatees

An increasing number of studies investigated the latent factor structure of posttraumatic stress disorder (PTSD) symptomatology following the new fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). To date, there is no consensus on the best representation of PTSD. This study examined six latent PTSD models in a sample of Filipino post-disaster relocatees (N = 523). Further investigation on the relationship of the best-fitting model to generalized anxiety disorder (GAD) in the latent level was conducted. The seven-factor hybrid model consisting of intrusion, avoidance, negative affect, anhedonia, externalizing behaviors, anxious arousal, and dysphoric arousal, was the best fitting model. Latent associations between the factors in the hybrid model and GAD suggest there are core and transdiagnostic features of PTSD. These findings have implications for understanding the underlying mechanism of PTSD and can inform the development of trauma-related interventions, particularly among post-disaster relocatees.
