Examining the Discriminant Validity of Complex Posttraumatic Stress Disorder and Borderline Personality Disorder Symptoms: Results From a United Kingdom Population Sample

Complex posttraumatic stress disorder (CPTSD) was added to the diagnostic nomenclature in the 11th revision of the International Classification of Diseases (ICD‐11). Although considerable evidence exists supporting the construct validity of CPTSD, the distinguishability of CPTSD symptoms from those of borderline personality disorder (BPD) has been questioned. The present study examined the discriminant validity of CPTSD and BPD symptoms among a trauma‐exposed population sample from the United Kingdom (N = 546). Participants completed self‐report measures of CPTSD and BPD symptoms, and their latent structure was assessed using exploratory structural equation modeling (ESEM). A three‐factor model with latent variables reflecting PTSD, disturbances in self‐organization (DSO), and BPD symptoms provided the best fit of the data, χ²(399, N = 546) = 1,650, p < .001; CFI = .944; TLI = .930; RMSEA = .077, 90% CI [.073, .081]. We identified multiple symptoms distinctive to individual constructs (e.g., disturbed relationships and suicidality) as well as symptoms shared across the constructs (e.g., affective dysregulation). The PTSD, β = .24; DSO, β = .23; and BPD, β = .27, latent variables were positively and significantly associated with childhood interpersonal trauma. The current findings support the discriminant validity of CPTSD and BPD symptoms and highlight various phenomenological signatures of each construct as well as demonstrate how these constructs share important similarities in symptom composition and exogenous correlates.     

Moderating Effects of a Postdisaster Intervention on Risk and Resilience Factors Associated With Posttraumatic Stress Disorder in Chinese Children

This study is an evaluation of a psychosocial intervention involving child and adolescent survivors of the 2008 Sichuan China earthquake. Sociodemographics, earthquake‐related risk exposure, resilience using the Connor‐Davidson Resilience Scale, and posttraumatic stress disorder (PTSD) using the UCLA‐PTSD Index were collected from 1,988 intervention participants and 2,132 controls. Mean resilience scores and the odds of PTSD did not vary between groups. The independent factors for risk and resilience and the dependent variable, PTSD, in the measurement models between control and intervention groups were equivalent. The structural model of risk and 2 resilience factors on PTSD was examined and found to be unequivalent between groups. In contrast to controls, risk exposure (B = ?0.32, p < .001) in the intervention group was negatively associated with PTSD. Rational thinking (B = ?0.48, p < .001), a resilience factor, was more negatively associated with PTSD in the intervention group. The second resilience factor explored, self‐awareness, was positively associated with PTSD in both groups (B = 0.46 for controls, p < .001, and B = 0.69 for intervention, p < .001). Results highlight the need for more cross‐cultural research in resilience theory to develop culturally appropriate interventions and evaluation measures.     

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.     

Emotion Dysregulation Prospectively Predicts Posttraumatic Stress Disorder Symptom Severity 3 Months After Trauma Exposure

Despite growing evidence in support of emotion dysregulation as a risk factor for the development of posttraumatic stress disorder (PTSD) following trauma exposure, few studies have examined temporal relations between emotion dysregulation and the onset and/or worsening of PTSD symptoms over time. The aim of the present study was to extend research on temporal associations between emotion dysregulation and PTSD in a sample of individuals recruited from hospital emergency departments soon after a traumatic event. Adult participants (N = 85; 62.4% female) completed self-report measures of emotion dysregulation and PTSD symptoms within 2 weeks of experiencing a traumatic event. Symptoms of PTSD were assessed approximately 3 months posttrauma. The results of a hierarchical linear regression analysis demonstrated that the inclusion of emotion dysregulation accounted for a significant amount of unique variance, β = .23, ΔR² = .04, p = .042, in 3-month PTSD symptom severity over and above other risk factors and baseline PTSD symptoms. No specific facet of emotion dysregulation emerged as a significant predictor of 3-month PTSD symptoms when all facets were included on the same step of the model, βs = −.04–.33, ps = .133–.954. These results demonstrate that posttraumatic emotion dysregulation may predict PTSD symptoms 3 months after trauma exposure. These findings are consistent with a growing body of literature that speaks to the relevance of emotional processes to the onset and maintenance of PTSD following exposure to a traumatic event.     

The Hong Kong Survey on the Epidemiology of Trauma Exposure and Posttraumatic Stress Disorder

This study examined the epidemiology of trauma exposure (TE) and posttraumatic stress disorder (PTSD) among community‐dwelling Chinese adults in Hong Kong. Multistage stratification sampling design was used, and 5,377 participants were included. In Phase 1, TE, probable PTSD (p‐PTSD), and psychiatric comorbid conditions were examined. In Phase 2, the Structured Clinical Interview for the DSM‐IV (SCID‐I) was used to determine the weighted diagnostic prevalence of lifetime full PTSD. Disability level and health service utilization were studied. The findings showed that the weighted prevalence of TE was 64.8%, and increased to 88.7% when indirect TE types were included, with transportation accidents (50.8%) reported as the most common TE. The prevalence of current p‐PTSD among participants with TE was 2.9%. Results of logistic regression suggested that nine specific trauma types were significantly associated with p‐PTSD; among this group, severe human suffering, sexual assault, unwanted or uncomfortable sexual experience, captivity, and sudden and violent death carried the greatest risks for developing PTSD, odds ratio (OR) = 2.32–2.69. The occurrence of p‐PTSD was associated with more mental health burdens, including (a) sixfold higher rates for any past‐week common mental disorder, OR = 28.4, (b) more mental health service utilization, p < .001, (c) poorer mental health indexes in level of symptomatology, suicide ideation and functioning, p < .001, and (d) more disability, ps < .001–p = .014. The associations found among TE, PTSD, and health service utilization suggest that both TE and PTSD should be considered public health concerns.     

Traumatic Event Exposure,Posttraumatic Stress Disorder,and Sleep Disturbances in a National Sample of U.S. Adults

Posttraumatic stress disorder (PTSD) is a highly prevalent, debilitating disorder found to develop after exposure to a potentially traumatic event (PTE). Individuals with PTSD often report sleep disturbances, specifically nightmares and insomnia, which are listed within the criteria for PTSD. This research examined prevalence of insomnia and nightmares within a national sample of 2,647 adults (data weighted by age and sex to correct for differences in sample distribution) who had been exposed to one or more PTEs. Prevalence of self‐reported sleep disturbance, sleep disturbances by PTE type, and gender differences were examined. All participants completed a self‐administered, structured online interview that assessed exposure to stressful events and PTSD symptoms. Among individuals who met DSM‐5 criteria for PTSD, a large majority (more than 92%) reported at least one sleep disturbance. Insomnia was relatively more prevalent than PTE‐related nightmares among individuals with PTSD and among all PTE‐exposed individuals. A higher number of PTEs experienced significantly increased the likelihood of both trauma‐related nightmares and insomnia, McFadden's pseudo R² = .07, p < .001. Women exposed to PTEs were more likely to endorse experience of insomnia, χ²(1, N = 2,647) = 99.13, p < .001, φ = .194, and nightmares compared to men, χ²(1, N = 2,648) = 82.98, p < .001, φ = .177, but this gender difference was not significant among individuals with PTSD, ps = .130 and .050, respectively. Differences in sleep disturbance prevalence by PTE type were also examined. Implications for treatment and intervention and future directions are discussed.     

Patterns of Treatment Disengagement and Personality Traits Associated With Posttraumatic Stress Disorder in Recent‐Era U.S. Veterans Receiving Cognitive Processing Therapy

Low treatment engagement is a barrier to implementation of empirically supported treatments for posttraumatic stress disorder (PTSD) among veterans. Understanding personality traits that predict dropout may help focus attempts to improve engagement. The current study included 90 veterans who served in recent conflicts in Iraq and/or Afghanistan and participated in a trial of cognitive processing therapy for PTSD. Goals were to characterize (a) personality correlates of PTSD, (b) patterns of engagement (i.e., attendance and homework completion), and (c) personality correlates of reduced engagement. Higher levels of PTSD symptoms were associated with a range of characteristics, including affective lability, r = .44 p < .001; anxiety, r = .38, p < .001; identity problems, r = .57, p < .001; intimacy problems, r = .34, p = .001; low affiliation, r = .33, p = .002; oppositionality, r = .36, p = .001; restricted expression, r = .35, p = .001; and suspiciousness, r = .50, p < .001. Notably, veterans with worse PTSD symptoms endorsed more cognitive dysregulation, r = .40, p < .001; and less insecure attachment, r = .14, p = .190, than expected. Only 52.2% of veterans completed the 12‐session course of treatment and 31.0% of participants completed fewer than six sessions. Personality traits did not predict attendance or homework completion. Disengagement continues to be a significant issue in trauma‐focused treatment for veterans with PTSD. Understanding veteran‐level factors, such as personality traits, may be useful considerations for future research seeking to understand and improve engagement.     

Perceived Social Support in Spanish Cancer Outpatients with Psychiatric Disorder

This study examines differences in perceived social support during oncology treatment of cancer patients, whilst taking into account the presence of psychiatric disorder. Of particular interest were cancer patients who received psychopharmacology treatment compared with those who did not. A total of 760 cancer outpatients were recruited from one hospital in Spain. Multivariate analysis of variance with the general linear model procedure was used. The Medical Outcomes Study Social Support Survey was used to assess social support perceived. The Diagnostic Interview Schedule using DSM‐III‐R criteria was utilized for the diagnosis of psychiatric disorders. There were significant differences between the patients diagnosed with a psychiatric disorder and those not diagnosed with psychiatric disorders in terms of perceived Emotional/Informational Support (F = 19.11, p < 0.01), Affectionate Support (F = 12.30, p < 0.01) and the Overall Support Index (F = 16.73, p < 0.01). In patients requiring psychopharmacology treatment, significant differences were presented with Structural Support (F = 4.32, p < 0.05), Emotional/Informational Support perceived (F = 7.87, p < 0.01), Instrumental Support (F = 4.17, p < 0.05) and Overall Support Index (F = 7.84, p < 0.01). Psychopharmacology treatment helped to increase the perception of social support received by the patient. Healthcare professionals could provide support that would normalize cancer patients' distress, taking into account the importance of perceived social support for the psychological well‐being of patients.

Pupillary Response to Affective Voices: Physiological Responsivity and Posttraumatic Stress Disorder

Posttraumatic stress disorder (PTSD) is related to dysfunctional emotional processing, thus motivating the search for physiological indices that can elucidate this process. Toward this aim, we compared pupillary response patterns in response to angry and fearful auditory stimuli among 99 adults, some with PTSD (n = 14), some trauma‐exposed without PTSD (TE; n = 53), and some with no history of trauma exposure (CON; n = 32). We hypothesized that individuals with PTSD would show more pupillary response to angry and fearful auditory stimuli compared to those in the TE and CON groups. Among participants who had experienced a traumatic event, we explored the association between PTSD symptoms and pupillary response; contrary to our prediction, individuals with PTSD displayed the least pupillary response to fearful auditory stimuli compared those in the TE, B = ?0.022, p = .077, and CON, B = ?0.042, p = .002, groups, but they did not differ on angry auditory stimuli, B = 0.019, p = .118 and B = 0.006, p = .634, respectively. It is important to note that within‐group analyses revealed that participants with PTSD differed significantly in their response to angry versus fearful stimuli, B = ?0.032, p = .015. We also found a positive association between PTSD symptoms and pupillary response to angry stimuli. Our findings suggest that differential pupil response to anger and fear stimuli may be a promising way to understand emotional processing in PTSD.     

Posttraumatic Stress Disorder and Complex Posttraumatic Stress Disorder in DSM‐5 and ICD‐11: Clinical and Behavioral Correlates

The American Psychiatric Association and the World Health Organization provide distinct trauma‐based diagnoses in the fifth edition of the Diagnostic and Statistical Manual (DSM‐5), and the forthcoming 11th version of the International Classification of Diseases (ICD‐11), respectively. The DSM‐5 conceptualizes posttraumatic stress disorder (PTSD) as a single, broad diagnosis, whereas the ICD‐11 proposes two “sibling” disorders: PTSD and complex PTSD (CPTSD). The objectives of the current study were to: (a) compare prevalence rates of PTSD/CPTSD based on each diagnostic system; (b) identify clinical and behavioral variables that distinguish ICD‐11 CPTSD and PTSD diagnoses; and (c) examine the diagnostic associations for ICD‐11 CPTSD and DSM‐5 PTSD. Participants in a predominately female clinical sample (N = 106) completed self‐report scales to measure ICD‐11 PTSD and CPTSD, DSM‐5 PTSD, and depression, anxiety, borderline personality disorder, dissociation, destructive behaviors, and suicidal ideation and self‐harm. Significantly more people were diagnosed with PTSD according to the DSM‐5 criteria (90.4%) compared to those diagnosed with PTSD and CPTSD according to the ICD‐11 guidelines (79.8%). An ICD‐11 CPTSD diagnosis was distinguished from an ICD‐11 PTSD diagnosis by higher levels of dissociation (d = 1.01), depression (d = 0.63), and borderline personality disorder (d = 0.55). Diagnostic associations with depression, anxiety, and suicidal ideation and self‐harm were higher for ICD‐11 CPTSD compared to DSM‐5 PTSD (by 10.7%, 4.0%, and 7.0%, respectively). These results have implications for differential diagnosis and for the development of targeted treatments for CPTSD.     

The Impact of Military Status on Cognitive Processing Therapy Outcomes in the Community

Military‐affiliated individuals (i.e., active duty personnel and veterans) exhibit high rates of posttraumatic stress disorder (PTSD). Although existing evidence‐based treatments for PTSD, such as cognitive processing therapy (CPT), have demonstrated effectiveness with military‐affiliated patients, there is evidence to suggest these individuals do not benefit as much as civilians. However, few studies have directly compared the effects of PTSD treatment between civilian and military‐affiliated participants. The current study compared treatment outcomes of military‐affiliated and civilian patients receiving CPT. Participants with PTSD who were either civilians (n = 136) or military‐affiliated (n = 63) received CPT from community‐based providers in training for CPT. Results indicated that military‐affiliated participants were equally likely to complete treatment, Log odds ratio (OR) = 0.14, p = .648. Although military‐affiliated participants exhibited reductions in PTSD, B = ?2.53, p < .001; and depression symptoms, B = ?0.65, p < .001, they experienced smaller reductions in symptoms relative to civilians: B = 1.15, p = .015 for PTSD symptoms and B = 0.29, p = .029 for depression symptoms. Furthermore, variability estimates indicated there was more variability in providers’ treatment of military‐affiliated versus civilian participants (i.e., completion rates and symptom reduction). These findings suggest that military‐affiliated patients can be successfully retained in trauma‐focused treatment in the community at the same rate as civilian patients, and they significantly improve in PTSD and depression symptoms although not as much as civilians. These findings also highlight community providers’ variability in treatment of military‐affiliated patients, providing support for more military‐cultural training.     

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.     

Emotion Dysregulation and Social Support in PTSD and Depression: A Study of Trauma‐Exposed Veterans

Emotion dysregulation has been associated with impaired interpersonal functioning and increased risk of posttraumatic psychopathology. Given that social support is a robust predictor of psychiatric morbidity following trauma exposure, we examined whether emotion dysregulation was associated with posttraumatic psychopathology through its negative effect on social support. Using self‐report data from 90 military veterans (89.9% men) enrolled in an outpatient psychotherapy program for posttraumatic stress disorder (PTSD), we found that social support partially mediated the effect of emotion dysregulation on PTSD (P_M = .10) and depression symptoms (P_M = .14). When source of support was considered, friend (P_M = .08) and significant other support (P_M = .06) were greater mediators of the effect of emotion dysregulation on depression symptoms than family support (P_M = .01). There were no differential mediating effects for support providers on PTSD symptoms. Our findings indicate that social support is a statistically significant yet clinically limited mechanism through which emotion dysregulation is linked with psychiatric symptoms. Implications for these limitations and alternative potentially relevant interpersonal mechanisms are discussed.     

The Bidirectional Dyadic Association Between Tendency to Forgive,Self‐Esteem,Social Support,and PTSD Symptoms Among Terror‐Attack Survivors and Their Spouses

This study examined the dyadic association of terror attack survivors’ and spouses’ internal resources, tendency to forgive (self, others, and situational forgiveness), self‐esteem, and the external resource of social support, as associated with victims’ and spouses’ posttraumatic stress disorder (PTSD) symptoms, using the actor–partner interdependence model. Based on lists by the One Family organization in Israel, 108 couples participated in the study. The study results demonstrate that in the dyad relationship, survivors’ tendency to forgive others and social support relate both to survivors’ decreased levels of PTSD symptom severity (β = ?.20, p = .021; β = ?.55 p < .001) and spouses’ decreased levels of PTSD symptom severity (β = ?.21, p = .015; β = ?.27, p = . 004), whereas spouses’ self‐esteem relates to both spouses’ and survivors’ decreased levels of PTSD symptom severity (β = ?.57, p < .001; β = ?.14, p = .041). The findings underscore the role of the survivor–spouse unit by highlighting the dyad relationship of internal and external resources as associated with both survivors’ and spouses’ PTSD symptoms. Theoretical and clinical implications of the findings are discussed.     

The Complex Trauma Inventory: A Self‐Report Measure of Posttraumatic Stress Disorder and Complex Posttraumatic Stress Disorder

The work group revising the criteria for trauma‐related disorders in the International Classification of Diseases (ICD‐11) made several changes. Specifically, they simplified the criteria for posttraumatic stress disorder (PTSD) and added a new trauma disorder called complex PTSD (CPTSD). These proposed changes to taxonomy require new instruments to assess these novel constructs. We developed a measure of PTSD and CPTSD (the Complex Trauma Inventory; CTI) according to the proposed domains, creating several items to assess each domain. We examined the factor structure of the CTI in two separate samples of diverse college students (n ₁ = 391; n ₂ = 391) who reported exposure to at least one traumatic event and at least occasional functional impairment. After reducing the original 50 items in the item pool to 20 items, confirmatory factor analyses supported two highly correlated second‐order factors—PTSD and disturbances in self‐organization (DSO)—with PTSD (i.e., reexperiencing, avoidance, sense of threat) and DSO (i.e., affect dysregulation, negative self‐concept, and disturbances in relationships), each loading on three of the six ICD‐11‐consistent first‐order factors, root mean square error of approximation (RMSEA) = .056, 95% confidence interval (CI) [.048, .064], comparative fit index (CFI) = .956, Tucker‐Lewis index (TLI) = .948, standardized root mean square residual (SRMR) = .043, Bayesian information criterion (BIC) = 641.55, χ²(163) = 361.02, p < .001. Internal consistencies for PTSD and DSO were good to excellent (Cronbach's αs = .89 to .92). Supplementary analyses supported the gender invariance of the CFA model, as well as convergent and discriminant validity of the CTI. The validity of the CTI supports the distinction between CPTSD and PTSD. Moreover, the CTI will assist clinicians with diagnosis, symptom tracking, treatment planning, and assessing outcomes.     

Coping Self‐Efficacy Moderates the Association Between Severity of Partner Violence and PTSD Symptoms Among Incarcerated Women

Previous research indicates self‐efficacy may function as a protective factor for survivors of partner violence (PV), including coping self‐efficacy specific to domestic violence. We hypothesized that domestic violence coping self‐efficacy would moderate the association between recent PV and posttraumatic stress disorder (PTSD) symptoms in a sample of incarcerated women, such that the association between PV and PTSD would be strongest at low levels of domestic violence coping self‐efficacy. Participants (N = 102) were incarcerated women who reported PV in the year prior to incarceration. They were aged 19–55 years (M = 33.57, SD = 9.32), identified predominantly as European American (84.3%), American Indian (15.7%), and Hispanic (14.7%), with 80.4% completing high school or more in terms of education. Participants responded to self‐report measures of PV, trauma history, domestic violence coping self‐efficacy, and current PTSD symptoms. In a series of sequential regression analyses, PV (β = .65, sr² = .06, p = .017) was significantly associated with current PTSD symptoms above and beyond past trauma history (β = .37, sr² = .14, p < .001), and this association was moderated by domestic violence coping self‐efficacy (Domestic Violence Coping Self‐Efficacy × Partner Violence; β = ?.54, sr² = .03, p = .044). The relationship between PV and PTSD symptoms was greatest at low and average levels of domestic violence coping self‐efficacy and nonsignificant at high levels of domestic violence coping self‐efficacy. These findings highlight the importance of assessing domestic violence coping self‐efficacy in incarcerated women with recent PV, given that domestic violence coping self‐efficacy appeared to be protective against symptoms of PTSD.     

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.     

Trauma Exposure,Posttraumatic Stress Disorder Symptoms Trajectory,and Disability Level Among Hospitalized Injury Survivors in Kenya

Potentially traumatic events (PTEs) have been consistently associated with posttraumatic stress disorder (PTSD). However, the extent of association and attribution to subsequent disability has varied, with limited studies conducted in urban low‐income contexts. This longitudinal study estimated the trajectory of PTSD symptoms up to 7 months after hospitalization and the associated disability level among adult patients who had been hospitalized due to injury. Adult injury patients (N = 476) admitted to Kenyatta National Hospital in Nairobi, Kenya, were interviewed in person in the hospital, and via phone at 1, 2–3, and 4–7 months after hospital discharge. Using latent growth curve modeling, two trajectories of PTSD symptoms emerged: (a) persistently elevated PTSD symptoms (9.2%), and (b) low PTSD symptoms (90.8%). Number of PTEs experienced remained moderately associated with the elevated trajectory after controlling for in‐hospital depressive symptoms. Having previously witnessed killings or serious injuries, AOR = 2.32, 95% CI [1.07, 5.05]; being female, AOR = 4.74, 95% CI [4.53, 4.96]; elevated depressive symptoms during hospitalization, AOR = 2.96, 95% CI [1.28, 6.83]; and having no household savings/assets, AOR = 1.28, 95% CI [1.13, 1.44], were associated with the elevated PTSD symptoms trajectory class after controlling for other risk factors. Latent membership in the elevated PTSD trajectory was associated with a significantly higher level of disability several months after hospital discharge, p < .001, after controlling for injury and demographic characteristics. These results underline the associations among in‐hospital depressive symptoms, witnessing atrocities, and poverty, and an elevated PTSD symptoms trajectory.     

Service Dogs for Veterans and Military Members With Posttraumatic Stress Disorder: Replication With the PTSD Checklist for DSM‐5

Psychiatric service dogs are an emerging complementary intervention for veterans and military members with posttraumatic stress disorder (PTSD). Recent cross‐sectional studies have documented significant, clinically relevant effects regarding service dogs and PTSD symptom severity. However, these studies were conducted using the PTSD Checklist (PCL) for the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM). The present study aimed to replicate and advance these findings using the latest version of the PCL for the fifth edition of the DSM (PCL‐5). Participants included 186 military members and veterans who had received a PTSD service dog (n = 112) or who were on the waitlist to receive one in the future (n = 74). A cross‐sectional design was used to investigate the association between having a service dog and PCL‐5 total and symptom cluster scores. After controlling for demographic variables, there was a significant association between having a service dog and lower PTSD symptom severity both in total, B = ‐14.52, p < .001, d = ‐0.96, and with regard to each symptom cluster, ps < .001, ds = ‐0.78 to ‐0.94. The results replicated existing findings using the largest sample size to date and the most recent version of the PCL. These findings provide additional preliminary evidence for the efficacy of service dogs as a complementary intervention for military members and veterans with PTSD and add to a growing body of foundational research serving to rationalize investment in the further clinical evaluation of this emerging practice.
