Posttraumatic Stress Disorder Symptoms and Reckless Behaviors: A Network Analysis Approach

Existing literature indicates a theoretical and empirical relation between engagement in reckless behaviors and posttraumatic stress disorder (PTSD). Thus, the DSM-5 revision of the PTSD nosology added a new “reckless or self-destructive behavior” (RSDB) symptom (Criterion E2). The current study applied a network analytic approach to examine the item-level relations among a range of reckless behaviors and PTSD symptom clusters. Participants were recruited from Amazon's Mechanical Turk (N = 417), and network analysis was conducted with 20 variables: six PTSD symptom clusters, corresponding to the hybrid model of PTSD (Armour et al., 2015) and excluding the externalizing behavior cluster (Community 1), and 14 items related to reckless behavior (Community 2). The results showed that the network associations were strongest within each construct (i.e., within PTSD and within reckless behaviors), although several bridge connections (i.e., between PTSD clusters and reckless behaviors) were identified. Most reckless behavior items had direct associations with one or more PTSD symptom clusters. The present findings support the existence of close relations between a variety of reckless behaviors and PTSD symptom clusters beyond their relations with DSM Criterion E2. The results provide testable hypotheses about the associations between specific reckless behaviors and PTSD symptom clusters, which may inform future research.     

The Association Between Negative Trauma‐Related Cognitions and Pain‐Related Functional Status Among Veterans With Posttraumatic Stress Disorder and Alcohol Use Disorder

Among veterans with posttraumatic stress disorder (PTSD), alcohol use disorders (AUDs) are highly prevalent. Furthermore, PTSD frequently co‐occurs with chronic pain (CP), and CP is associated with an increased risk of AUD. Pain‐related beliefs and appraisals are significantly associated with poorer pain‐related functional status, yet few studies have examined negative trauma‐related cognitions and their impact on pain‐related functional disability in veterans with co‐occurring PTSD and AUD. Accordingly, we examined the association between negative trauma‐related cognitions and pain severity and pain disability in 137 veterans seeking treatment for PTSD and AUD. Using hierarchical multiple linear regression, we found that higher levels of negative trauma‐related cognitions (e.g., “I am completely incompetent”) were associated with a higher level of pain severity, after controlling for PTSD symptom severity and frequency of alcohol use, total R² = .07, ΔR² = .06. Additionally, as hypothesized, we found that higher levels of negative trauma‐related cognitions were associated with higher levels of pain disability, after controlling for PTSD symptom severity, frequency of alcohol use, and pain severity, total R² = .46, ΔR² = .03. Given that negative trauma‐related cognitions contributed to pain severity and pain disability, even when controlling for PTSD severity and frequency of alcohol use, future studies should explore the potential impact of interventions that address negative trauma‐related cognitions (e.g., prolonged exposure or cognitive processing therapy) on pain severity and disability.     

Validation of the Pittsburgh Sleep Quality Index Addendum for Posttraumatic Stress Disorder (PSQI‐A) in U.S. Male Military Veterans

Sleep disturbances are core symptoms of posttraumatic‐stress disorder (PTSD), yet they bear less stigma than other PTSD symptoms. Given the growing number of returning military veterans, brief, valid assessments that identify PTSD in a minimally stigmatizing way may be useful in research and clinical practice. The study purpose was to evaluate the psychometric properties of the Pittsburgh Sleep Quality Index Addendum for PTSD (PSQI‐A), and to examine its ability to identify PTSD cases among U.S. male military veterans. Male military veterans (N = 119) completed the PSQI‐A, as well as measures of sleep quality, combat exposure, posttraumatic stress, depression, and anxiety. Veterans with PTSD had higher PSQI‐A identified disruptive nocturnal behaviors than veterans without PTSD. The PSQI‐A had good internal consistency and convergent validity with sleep quality, combat exposure, PTSD symptoms, depression, and anxiety. A cutoff score ≥ 4 provided an area under the curve = .81, with 71% sensitivity, 82% specificity, and 60% positive and 83% negative predictive value for a clinical diagnosis of PTSD; correct classification was 74%. The PSQI‐A is a valid measure to possibly detect PTSD among male military veterans. Assessment of disruptive nocturnal behaviors may provide a cost‐effective, nonstigmatizing approach to PTSD screening without directly probing for trauma exposure(s).     

Self‐Compassion as a Prospective Predictor of PTSD Symptom Severity Among Trauma‐Exposed U.S. Iraq and Afghanistan War Veterans

U.S. combat veterans of the Iraq and Afghanistan wars have elevated rates of posttraumatic stress disorder (PTSD) compared to the general population. Self‐compassion, characterized by self‐kindness, a sense of common humanity when faced with suffering, and mindful awareness of suffering, is a potentially modifiable factor implicated in the development and maintenance of PTSD. We examined the concurrent and prospective relationship between self‐compassion and PTSD symptom severity after accounting for level of combat exposure and baseline PTSD severity in 115 Iraq and Afghanistan war veterans exposed to 1 or more traumatic events during deployment. PTSD symptoms were assessed using the Clinician Administered PTSD Scale for DSM‐IV (CAPS‐IV) at baseline and 12 months (n =101). Self‐compassion and combat exposure were assessed at baseline via self‐report. Self‐compassion was associated with baseline PTSD symptoms after accounting for combat exposure (β = ?.59; p < .001; ΔR² = .34; f² = .67; large effect) and predicted 12‐month PTSD symptom severity after accounting for combat exposure and baseline PTSD severity (β = ?.24; p = .008; ΔR² = .03; f² = .08; small effect). Findings suggest that interventions that increase self‐compassion may be beneficial for treating chronic PTSD symptoms among some Iraq and Afghanistan war veterans.     

Military and Premilitary Trauma,Attachment Orientations,and Posttraumatic Stress Disorder Severity Among Male and Female Veterans

Samples in prior studies examining attachment theory in the military have been predominantly composed of male combat veterans. Given the rates of sexual trauma among female veterans and differences in the association between attachment and posttraumatic stress disorder (PTSD) severity for sexual trauma survivors, it was necessary to consider the attachment characteristics of veterans within a mixed‐sex sample. Participants were a mixed‐sex veteran sample seeking inpatient trauma‐related treatment (N = 469). Using independent samples t tests, we examined sex differences in attachment. Consistent with our hypothesis, women reported a higher level of attachment anxiety than did men, t(351) = ?2.12, p = .034. Women also reported a higher level of attachment avoidance, t(351) = ?2.44, p = .015. Using hierarchical regression, we examined the contribution of attachment anxiety and avoidance to PTSD severity, partialing out variance accounted for by demographic variables and traumatic experiences. Consistent with our hypotheses, attachment avoidance predicted PTSD severity on the Clinician‐Administered PTSD Scale for DSM‐IV (CAPS), β = .20, p < .001, and the PTSD Checklist–Civilian Version (PCL‐C), β = .18, p < .001. Attachment anxiety did not predict CAPS severity but did predict PCL‐C severity, β = .11, p = .020. These results suggest the association between attachment avoidance and PTSD is not exclusive to combat trauma and may apply more generally to the larger veteran population. Higher levels of attachment anxiety and avoidance among female veterans potentially implicate the presence of greater attachment fearfulness among this particular subpopulation of veterans.     

Predictors of Treatment Interest and Treatment Initiation in a VA Outpatient Trauma Services Program Providing Evidence‐Based Care

The present study explored interest in treatment and treatment initiation patterns among veterans presenting at a VA posttraumatic stress disorder (PTSD) clinic. U.S. veterans who were referred for treatment of posttraumatic stress symptoms (N = 476) attended a 2‐session psychoeducation and orientation class where they completed measures of demographic variables, PTSD and depression symptom severity, and interest in treatment. Consistent with previous literature and our hypotheses, Vietnam (OR = 1.78) and Persian Gulf veterans (OR = 2.05) were more likely than Iraq and Afghanistan veterans to initiate treatment. Veterans reporting more severe PTSD and depression symptoms were more likely to initiate treatment than not (OR for PTSD = 1.02, OR for depression = 1.02). Interest in treatment emerged as a strong predictor of treatment initiation. Specifically, interest in trauma‐focused treatment showed a significant independent predictive effect on initiation such that veterans who expressed interest in trauma‐focused treatment were significantly more likely to initiate treatment than those who did not express interest (OR = 2.13). Building interest in trauma‐focused treatment may be a vital component for engaging veterans in evidence‐based trauma‐focused therapy.     

A Dyadic Analysis of the Influence of Trauma Exposure and Posttraumatic Stress Disorder Severity on Intimate Partner Aggression

This study used structural equation modeling to evaluate a mediation model of the relationship between trauma exposure, posttraumatic stress disorder (PTSD) symptoms, and perpetration of intimate partner physical and psychological aggression in trauma‐exposed veterans and their cohabitating spouses (n = 286 couples; 88% male veteran and female spouse, 80.8% White, non‐Hispanic). Dyadic data analyses were used to simultaneously evaluate actor and partner effects using the actor–partner interdependence model (Kashy & Kenny, 2000). The primary hypothesis was that PTSD would mediate the association between trauma exposure and intimate partner physical and psychological aggression with these effects evident both within and across members of a couple (i.e., actor and partner effects). The best‐fitting model included (a) equivalent actor and partner direct effects of trauma on veterans’ acts of psychological aggression (β = .17 to .20, p = .001), and (b) equivalent actor and partner indirect effects via PTSD on veterans’ acts of physical aggression (β = .08 to .10, p < .001). There were no direct or indirect effects predicting the spouses’ aggression. Results suggest it is important to consider the trauma histories and possible presence of PTSD in both partners as this may be a point of intervention when treating distressed couples.     

Associations Between Trauma‐Related Rumination and Symptoms of Posttraumatic Stress and Depression in Treatment‐Seeking Female Veterans

Trauma‐related rumination is a cognitive style characterized by repetitive negative thinking about the causes, consequences, and implications of a traumatic experience. Frequent trauma‐related rumination has been linked to posttraumatic stress disorder (PTSD) and depression in civilian samples but has yet to be examined among military veterans. This study extended previous research by examining trauma‐related rumination in female veterans who presented to a Veterans Affairs women's trauma recovery clinic (N = 91). The study had two main aims: (a) to examine associations between trauma‐related rumination and specific PTSD symptoms, adjusting for the overlap between trauma‐related rumination and other relevant cognitive factors, such as intrusive trauma memories and self‐blame cognitions; and (b) to assess associations between trauma‐related rumination, PTSD, and depression, adjusting for symptom comorbidity. At intake, patients completed a semistructured interview and self‐report questionnaires. Primary diagnoses were confirmed via medical record review. Trauma‐related rumination was common, with more than 80% of patients reporting at least sometimes engaging in this cognitive style in the past week. After adjusting for other relevant cognitive factors, trauma‐related rumination was significantly associated with several specific PTSD symptoms, r_ps = .33–.48. Additionally, the severity of trauma‐related rumination was associated with overall PTSD symptom severity, even after adjusting for comorbid depression symptoms, r_p² = .35. In contrast, the association between trauma‐related rumination and depressive symptom severity was not significant after adjusting for comorbid PTSD symptoms, r_p² = .008. These results highlight trauma‐related rumination as a unique contributing factor to the complex clinical presentation for a subset of trauma‐exposed veterans.     

Impact of Self‐Blame on Cognitive Processing Therapy: A Comparison of Treatment Outcomes

Research suggests that cognitive processing therapy (CPT) may be a particularly well‐suited intervention for trauma survivors who endorse self‐blame; however, no study has examined the impact of self‐blame on response to CPT. Accordingly, the current study compared response to CPT between two groups of veterans seeking residential treatment for posttraumatic stress disorder (PTSD). In one group, participants endorsed low self‐blame at pretreatment (n = 133) and in the other group, participants endorsed high self‐blame (n = 133). Results from multilevel modeling analysis suggest that both groups experienced significant reductions in PTSD symptoms as measured by the PTSD Checklist, B = ?1.58, SE = 0.11; 95% CI [?1.78, ?1.37]; t(1654) = ?14.97, p < .001. After controlling for pretreatment symptom severity and additional covariates, there was no difference in treatment response between the low‐ and high‐self‐blame groups, Time × Self‐blame interaction: B = 0.18, SE = 0.12; 95% CI = [?0.06, 0.42]; t(1646) = 1.49, p = .138. This suggests that CPT is an effective treatment for individuals exposed to trauma, regardless of level of self‐blame.     

Trauma‐Related Pain,Reexperiencing Symptoms,and Treatment of Posttraumatic Stress Disorder: A Longitudinal Study of Veterans

Research has demonstrated a strong positive association between posttraumatic stress disorder (PTSD) symptoms and physical pain. However, few studies have explored the impact of pain problems on the symptoms and treatment of PTSD, and results remain inconsistent. This longitudinal study examined whether trauma‐related and trauma‐unrelated pain differentially and uniquely predicted reexperiencing symptoms. We also examined whether levels of reexperiencing symptoms mediated the relationship between pain intensity and posttreatment symptoms of avoidance, numbing, and hyperarousal (ANH). Analyses were conducted using archival data from 99 treatment‐seeking veterans who reported the etiology and intensity of their pain and severity of PTSD symptoms pre‐ and posttreatment. Among veterans with trauma‐related pain, pain intensity (a) uniquely corresponded to greater posttreatment reexperiencing symptoms (b  = 1.09), and (b) was indirectly predictive of ANH symptoms via the reexperiencing symptoms (b  = 1.93). However, veterans with trauma‐unrelated pain evidenced no associations between pain intensity and reexperiencing (b  = 0.04) or ANH symptoms (b  = 0.06). We thus found that trauma‐related pain was indirectly related to poor PTSD treatment outcomes via reexperiencing symptoms. These findings offer additional insight into factors that may influence PTSD treatment outcomes for pain‐suffering trauma survivors.     

Response to Cognitive Processing Therapy in Veterans With and Without Obstructive Sleep Apnea

Recent studies have called attention to the need for enhancing treatment outcome in trauma‐focused psychotherapies, such as cognitive processing therapy (CPT), with veterans. Given the prevalence of posttraumatic‐related sleep disturbances, and the role of sleep in emotional learning and processing, sleep quality may be a target for improving CPT outcome. Elevated rates of obstructive sleep apnea (OSA) have been reported in samples of veterans with posttraumatic stress disorder (PTSD); however, the impact of OSA on response to CPT is unclear. In this study, CPT outcome was examined in veterans with and without a diagnosis of OSA. Following chart review, 68 OSA‐positive and 276 OSA‐negative veterans were identified. Generalized estimating equations were used to compare between‐group differences in weekly self‐reported PTSD symptomatology. The OSA‐positive veterans reported greater PTSD severity over the course of treatment and at posttreatment compared with veterans without OSA (B = −0.657). Additionally, OSA‐positive veterans with access to continuous positive airway pressure (CPAP) therapy reported less PTSD severity relative to OSA‐positive veterans without access to CPAP (B = −0.421). Apnea appears to be a contributing factor to the reduced effectiveness of evidence‐based psychotherapy for veterans with PTSD; however, preliminary evidence indicates that CPAP therapy may help mitigate the impact of OSA on treatment outcome.     

Punishment Learning in U.S. Veterans With Posttraumatic Stress Disorder

Learning processes have been implicated in the development and course of posttraumatic stress disorder (PTSD); however, little is currently known about punishment‐based learning in PTSD. The current study investigated impairments in punishment‐based learning in U.S. veterans. We expected that veterans with PTSD would demonstrate greater punishment‐based learning compared to a non‐PTSD control group. We compared a PTSD group with and without co‐occurring depression (n = 27) to a control group (with and without trauma exposure) without PTSD or depression (n = 29). Participants completed a computerized probabilistic punishment‐based learning task. Compared to the non‐PTSD control group, veterans with PTSD showed significantly greater punishment‐based learning. Specifically, there was a significant Block × Group interaction, F(1, 54) = 4.12, p = .047, η² = .07. Veterans with PTSD demonstrated greater change in response bias for responding toward a less frequently punished stimulus across blocks. The observed hypersensitivity to punishment in individuals with PTSD may contribute to avoidant responses that are not specific to trauma cues.     

Cumulative Trauma Exposure,Emotion Regulation,and Posttraumatic Stress Disorder Among Incarcerated Women

Incarcerated women report high rates of trauma exposure and posttraumatic stress disorder (PTSD). Emotion regulation has been identified as a potential mechanism that contributes to the association between trauma exposure and PTSD severity. The present study examined associations among cumulative trauma exposure, emotion regulation difficulties, and current (30‐day) PTSD in 152 randomly selected women in prison. Utilizing structural equation modeling (SEM), results indicated cumulative trauma was significantly associated with emotion regulation difficulties, β = .31, SE = .13, p  = .005; and PTSD symptom severity, β = .41, SE = .14, p  = .005. We identified a significant indirect effect, 0.11, z = 2.37, p = .018, of emotion regulation on the association between cumulative trauma exposure and severity of current PTSD symptoms. These findings are consistent with previous longitudinal research suggesting that emotion regulation is significantly affected by trauma exposure, and they support previously identified associations between emotion regulation difficulties and severity of PTSD. Further, these findings have the potential to inform current efforts to identify and implement effective PTSD‐focused interventions with incarcerated women. In particular, it appears that emotion regulation skills may be an important component of effective PTSD focused interventions for this population.     

Effects of Threat Context,Trauma History,and Posttraumatic Stress Disorder Status on Physiological Startle Reactivity in Gulf War Veterans

In the current study, we explored exaggerated physiological startle responses in posttraumatic stress disorder (PTSD) and examined startle reactivity as a biomarker of PTSD in a large veteran sample. We assessed heart rate (HR), skin conductance (SC), and electromyographic (EMG) startle responses to acoustic stimuli under low‐, ambiguous‐, and high‐threat conditions in Gulf War veterans with current (n = 48), past (n = 42), and no history of PTSD (control group; n = 152). We evaluated PTSD status using the Clinician‐Administered PTSD Scale and trauma exposure using the Trauma History Questionnaire. Participants with current PTSD had higher HR, ds = 0.28–0.53; SC, d = 0.37; and startle responses than those with past or no history of PTSD. The HR startle response under ambiguous threat best differentiated current PTSD; however, sensitivity and specificity analyses revealed it to be an imprecise indicator of PTSD status, ROC AUC = .66. Participants with high levels of trauma exposure only showed elevated HR and SC startle reactivity if they had current PTSD. Results indicate that startle is particularly elevated in PTSD when safety signals are available but a possibility of danger remains and when trauma exposure is high. However, startle reactivity alone is unlikely to be a sufficient biomarker of PTSD.     

Temporal Associations Between Moral Injury and Posttraumatic Stress Disorder Symptom Clusters in Military Veterans

War zone veterans who experience posttraumatic stress disorder (PTSD) symptoms might struggle with co‐occurring cognitive, emotional, and behavioral expressions of suffering that align with conceptual definitions of moral injury (MI). However, given that PTSD is a multidimensional condition, disentangling the apparent interplay with MI may inform clinical practice and research. This study incorporated a cross‐lagged design to explore temporal associations between self‐ and other‐directed outcomes related to MI and severity of DSM‐5 PTSD symptom clusters while accounting for depressive symptoms. Drawing on the Expressions of Moral Injury Scale–Military Version in a community sample of 182 previously deployed veterans, MI‐related outcomes were linked with severity of PTSD symptom clusters at two assessments spaced apart by 6 months, rs = .58–.62. Of possible models for conceptualizing the temporal nature of these associations, structural equation modeling analyses revealed a cross‐lagged primary MI model best fit veterans’ responses. Within this model, veterans’ self‐directed MI at Time 1 predicted greater PTSD symptoms at the 6‐month follow‐up. However, an equivalent cross‐lagged path also emerged between Time 1 PTSD Cluster D symptoms and self‐directed MI at Time 2, suggesting the value of a reciprocal MI model for this symptom domain. In contrast, other‐directed outcomes of MI were not linked with PTSD in the presence of other variables. Overall, these findings support the prognostic value of assessing for MI‐related outcomes among veterans who might be struggling with PTSD symptomatology, particularly with respect to self‐directed problems associated with enduring moral distress.     

Deliberate Self‐Harm and Suicidal Ideation Among Male Iraq/Afghanistan‐Era Veterans Seeking Treatment for PTSD

The objectives of the present research were to examine the prevalence of deliberate self‐harm (DSH) among 214 U.S. male Iraq/Afghanistan‐era veterans seeking treatment for posttraumatic stress disorder (PTSD) and to evaluate the relationship between DSH and suicidal ideation within this population. Approximately 56.5% (n = 121) reported engaging in DSH during their lifetime; 45.3% (n = 97) reported engaging in DSH during the previous 2 weeks. As hypothesized, DSH was a significant correlate of suicidal ideation among male Iraq/Afghanistan‐era veterans, OR = 3.88, p < .001, along with PTSD symptom severity, OR = 1.03, p < .001, and combat exposure, OR = 0.96, p = .040. A follow‐up analysis identified burning oneself, OR = 17.14, p = .017, and hitting oneself, OR = 7.93, p < .001, as the specific DSH behaviors most strongly associated with suicidal ideation. Taken together, these findings suggest that DSH is quite prevalent among male Iraq/Afghanistan‐era veterans seeking treatment for PTSD and is associated with increased risk for suicidal ideation within this population. Routine assessment of DSH is recommended when working with male Iraq/Afghanistan veterans seeking treatment for PTSD.     

Mindfulness,Self‐Compassion,Posttraumatic Stress Disorder Symptoms,and Functional Disability in U.S. Iraq and Afghanistan War Veterans

Mindfulness and self‐compassion are overlapping, but distinct constructs that characterize how people relate to emotional distress. Both are associated with posttraumatic stress disorder (PTSD) and may be related to functional disability. Although self‐compassion includes mindful awareness of emotional distress, it is a broader construct that also includes being kind and supportive to oneself and viewing suffering as part of the shared human experience—a potentially powerful way of dealing with distressing situations. We examined the association of mindfulness and self‐compassion with PTSD symptom severity and functional disability in 115 trauma‐exposed U.S. Iraq/Afghanistan war veterans. Mindfulness and self‐compassion were each uniquely, negatively associated with PTSD symptom severity. After accounting for mindfulness, self‐compassion accounted for unique variance in PTSD symptom severity (f² = .25; medium ES). After accounting for PTSD symptom severity, mindfulness and self‐compassion were each uniquely negatively associated with functional disability. The combined association of mindfulness and self‐compassion with disability over and above PTSD was large (f² = .41). After accounting for mindfulness, self‐compassion accounted for unique variance in disability (f² = .13; small ES). These findings suggest that interventions aimed at increasing mindfulness and self‐compassion could potentially decrease functional disability in returning veterans with PTSD symptoms.     

Trauma Exposure and Posttraumatic Stress Disorder in Adolescents: A National Survey in Switzerland

There are a limited number of epidemiological studies that have focused on trauma exposure and prevalence of posttraumatic stress disorder (PTSD) in representative general population samples of adolescents, especially outside of the United States. We therefore aimed to assess the lifetime prevalence of traumatic events (TEs) and current prevalence of PTSD, and to examine demographic risk factors for TEs and PTSD in a representative sample of adolescents. Data were collected by a school survey among a sample of 6,787 9th‐grade students in Switzerland. Roughly 56% of the adolescents (females 56.6%; males 55.7%) reported having experienced at least 1 TE. Non‐Swiss nationality (OR = 1.80), not living with both biological parents (OR = 1.64), and lower parental education (OR = 1.18) were associated with a higher risk of trauma exposure. The current prevalence of PTSD according to the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; DSM‐IV‐TR; American Psychiatric Association, 2000) criteria was 4.2% (females 6.2%; males 2.4%). Female gender (OR = 2.70), not living with both biological parents (OR = 1.47), lower parental education (OR = 1.51), and exposure to multiple TEs (OR = 9.56) were significant risk factors for PTSD. Results suggest considerably high rates of TEs and PTSD among adolescents. Intervention efforts must be intensified to reduce trauma exposure and treat PTSD.     

Acute stress disorder and posttraumatic stress disorder in parents of injured children

Acute stress disorder (ASD) and posttraumatic stress disorder (PTSD) were examined in 334 parents of children with traffic‐related injuries. In the first month after their child's injury, 12% of parents had ASD and another 25% had partial ASD. Among 251 parents assessed again approximately 6 months postinjury, 8% had PTSD and another 7% had partial PTSD. The ASD and PTSD severity were associated (r = .54), but ASD status was not a sensitive predictor of later PTSD. Independent predictors of ASD severity included prior trauma exposure, peritrauma exposure and perceptions of the child's pain and life threat, and child ASD severity. Independent predictors of PTSD severity included prior trauma exposure, parent ASD severity, and parent‐rated child physical health at follow‐up.
