Residential Posttraumatic Stress Disorder Treatment Research Articles

Examining the associations between posttraumatic stress disorder symptom clusters across cognitive processing therapy.

Cognitive processing therapy (CPT) is a well-known trauma-focused treatment that aims to generate more adaptive posttrauma cognitions and emotions. Changes in cognitions are theorized to be the mechanism by which CPT leads to improvement in posttraumatic stress disorder (PTSD) symptoms. The present study aimed to explore associations between changes in PTSD symptom clusters during CPT. We hypothesized that early changes in negative alterations in cognitions and mood (NACM) would correlate with later changes in other symptom clusters. Data were collected from 296 veterans participating a 7-week PTSD residential treatment program at a U.S. Veterans Affairs medical center. PTSD symptoms were assessed at pretreatment (Week 1), midtreatment (Week 4), and posttreatment (Week 7). Cross-lagged path analyses demonstrated that pretreatment-to-midtreatment improvement in NACM was correlated with midtreatment-to-posttreatment improvement in avoidance, β =.52, though this association was bidirectional, suggesting pretreatment-to-midtreatment improvements in either cluster may be correlated with midtreatment-to-posttreatment improvements. Similarly, pretreatment-to-midtreatment improvement in intrusions, β =.40, and arousal, β =.49, were correlated with later improvement in avoidance, suggesting avoidance may improve after improvement in other clusters. Interestingly, pretreatment-to-midtreatment arousal improvement was significantly correlated with midtreatment-to-posttreatment NACM improvement, β =.27, though the reverse was nonsignificant, whereas a bidirectional association between arousal and intrusions emerged, β =.34, β =.53. Early changes in arousal were correlated with later changes in several other symptom clusters, whereas other clusters demonstrated bidirectional associations. These results may inform understanding of symptom improvement timing across CPT, which may aid in treatment selection and planning.

Unraveling PTSD: Symptom cluster change during and 1 year after veterans' residential PTSD treatment.

Although treatment of posttraumatic stress disorder (PTSD) is effective in reducing symptom severity, remission rates are low. One potential underlying reason for treatment ineffectiveness is differential response of specific PTSD symptom clusters. Using data from a national Veterans Affairs (VA) residential PTSD treatment cohort, we conducted a longitudinal study to examine changes in Diagnostic and Statistical Manual of Mental Disorders, fifth edition PTSD symptom clusters from admission to 1-year follow-up. PTSD symptom data were analyzed from a national cohort of veterans who completed VA PTSD residential treatment between October 2019 and September 2020 (n = 1,648; 13% women; median age 44.2 years). Endorsement (%) and severity (M[SD]) of PTSD clusters and individual symptoms were compared at admission, discharge, 4-month and 1-year follow-ups. Large magnitude reductions in all four PTSD symptom clusters were observed from admission to discharge and both follow-ups; however, endorsement of all symptom clusters remained high. Intrusions (Cluster B) were the most highly endorsed at discharge and follow-up, whereas avoidance symptoms (Cluster C) were the least highly endorsed. Differential patterns of change were observed among the 20 individual PTSD symptoms; for example, flashbacks decreased during treatment, but increased to near admission levels by 1-year postdischarge. Results suggest that intrusive symptoms may be more resistant to residential treatment for PTSD and contribute to lower likelihood of treatment success. Future work is needed to examine differential treatment response for PTSD clusters, to inform the improvement of current and creation of novel treatment interventions, and to better address intrusive symptoms to maximize PTSD treatment gains.

Comparing effectiveness of residential versus intensive virtual treatment for veterans with posttraumatic stress disorder.

During the COVID-19 pandemic, restrictions imposed on residential treatment programs necessitated rapid implementation of virtual treatment delivery. Posttraumatic stress disorder (PTSD) Residential Rehabilitation Treatment Programs (P-RRTP) are a key mental health treatment for Veterans with PTSD who require more intensive interventions than outpatient care. During the pandemic, the W. G. (Bill) Hefner VA Healthcare System developed and implemented a Virtual Intensive Outpatient Program for PTSD (VIOPP) to meet the needs of the Veteran population. The purpose of this analysis was to compare the effectiveness of VIOPP to P-RRTP. Analyses included N = 370 Veterans, n = 193 who completed P-RRTP between January 2018 to April 2020 and n = 177 who completed VIOPP between June 2020 and November 2022 and provided pre- and posttreatment scores. Pre- and posttreatment scores of the PTSD Checklist for DSM-5 (PCL-5) were available for all patients. Pre- and posttreatment depressive symptom scores from the Nine-item Patient Health Questionnaire (PHQ-9) were available for n = 254 Veterans. Paired and independent samples t tests evaluated differences in change scores overall and by treatment modality (residential vs. virtual). Results indicated a significant decrease in PCL-5 scores regardless of treatment modality, p < .001. Despite beginning VIOPP with significantly higher PCL-5 scores than P-RRTP, there were no significant differences in PCL-5 change scores between virtual (M = -16.94) and residential treatment (M = -17.10), p = .910. PHQ-9 scores also decreased significantly for both treatment groups. These analyses suggest that intensive virtual treatment has similar effectiveness to residential treatment for PTSD. This supports the development of intensive virtual interventions as viable alternatives to residential treatments and a valuable component within the continuum of PTSD care.

PTSD, depression, and treatment outcomes: A latent profile analysis among active duty personnel in a residential PTSD program

Depression frequently co-occurs with posttraumatic stress disorder (PTSD), including among active duty service members. However, symptom heterogeneity of this comorbidity is complex and its association with treatment outcomes is poorly understood, particularly among active duty service members in residential treatment. This study used latent profile analysis (LPA) to identify symptom-based subgroups of PTSD and depression among 282 male service members in a 10-week, residential PTSD treatment program with evidence-based PTSD psychotherapies and adjunctive interventions. The PTSD Checklist–Military Version and Patient Health Questionnaire-8 were completed by service members at pre- and posttreatment and weekly during treatment. Multilevel models compared subgroups on PTSD and depression symptom change across treatment. LPA indicated four subgroups provided optimal fit: Depressive (high depression severity, low PTSD avoidance; n = 33, 11.7%), Avoidant (high PTSD avoidance, moderate depression severity; n = 89, 31.6%), Moderate (moderate PTSD and depression severity; n = 27, 9.6%), and Distressed (high PTSD and depression severity; n = 133, 47.2%). Treatment response differed across classes for both PTSD and depression outcomes (time × LPA class interaction ps < 0.001). In PTSD models, post-hoc comparisons indicated the Moderate class was associated with less PTSD symptom improvement relative to the other classes (ps < 0.006). In depression models, symptom reduction was greatest for the Distressed and Depressive subgroups relative to the other two classes (ps < 0.009). Study results provide an initial model for two prevalent, impairing disorders among service members and show how these symptom-based subgroups may differentially respond to residential PTSD treatment.

Residual posttraumatic stress disorder and depression symptoms following a residential posttraumatic stress disorder treatment program for U.S. active duty service members.

Even after the most effective posttraumatic stress disorder (PTSD) treatments, symptoms often persist. Understanding residual symptoms is particularly relevant in military populations, who may be less responsive to PTSD interventions. The sample consisted of 282 male service members who engaged in a residential PTSD treatment program at a military treatment facility that provided evidence-based PTSD psychotherapies and adjunctive interventions. PTSD and depression symptoms were assessed before and after treatment and weekly during treatment via the PTSD Checklist-Military Version and Patient Health Questionnaire-8. Logistic regression with Hochberg's step-up procedure compared the likelihood of individual residual symptoms between service members who did (n = 92, 32.6%) and did not (n = 190, 67.4%) experience clinically significant PTSD change (≥ 10-point PTSD Checklist-Military Version reduction). Not achieving clinically significant PTSD change was associated with greater odds of nearly all residual symptoms (OR = 2.03-6.18), excluding two Patient Health Questionnaire-8 items (appetite and psychomotor changes). Among service members experiencing clinically significant PTSD change, concentration difficulties (73.3%), physical reactions to reminders (71.1%), and intrusions (70.8%) were PTSD symptoms most likely to persist. Poor sleep (56.2%), low energy (50.0%), and concentration difficulties (48.3%) were the most common for depression. To our knowledge, this study is the first to examine residual PTSD and depression symptoms following residential PTSD treatment for active duty service members. Given the low rates of clinically significant PTSD change and the high frequency of residual symptoms, strategies may be needed to improve residential PTSD treatment outcomes in the military.

What Happens Next? Maintenance of Gains After Discharge From VA Residential PTSD Treatment.

Residential posttraumatic stress disorder (PTSD) treatment in the Department of Veterans Affairs is helpful for many Veterans, yet the majority experience symptom rebound after discharge. This study examined a national cohort of Veterans (n = 1872) who completed VA residential PTSD treatment and identified factors associated with maintenance of gains from discharge to 4-month follow-up. We generated three logistic regression models based on response profiles during residential treatment. In the "marginal responders" group, 1-3 "booster" sessions of PTSD treatment were associated with decreased odds of maintenance of gains (odds ratio [OR], 0.42), whereas in the "clinically significant responders" group, these sessions were associated with increased odds of maintenance of gains (OR, 2.89). Greater pain severity was associated with decreased odds of maintenance of gains in the "clinically significant responder" group (OR, 0.90). Results demonstrate several avenues for intervention including targeting pain severity and matching aftercare psychotherapy to Veteran residential treatment response.

Evidence-based treatment for posttraumatic stress disorder decreases suicidal ideation by reducing perceived burdensomeness among veterans in an outpatient program.

Evidenced-based posttraumatic stress disorder (PTSD) treatments generally reduce suicidal ideation (SI), and the interpersonal theory of suicide (ITS) may theoretically account for this finding. The ITS posits that SI stems from feeling like a burden (i.e., perceived burdensomeness) and a lack of belonging (i.e., thwarted belongingness). Previous research suggests that change in PTSD severity has a significant indirect effect on change in SI through changes in perceived burdensomeness, but not thwarted belongingness, among patients receiving residential PTSD treatment in a Veterans Affairs (VA) medical center; however, no research has investigated these associations in an outpatient VA setting with fewer confounding factors that might affect ITS constructs. Therefore, the current sample included veterans (N = 126) who completed PTSD treatment and pre- and posttreatment assessments in a VA outpatient clinic. Results from parallel models of multiple indirect effects suggest that change in PTSD severity was indirectly associated with change in SI through changes in perceived burdensomeness, B = 0.35, p < .001; β = .36, p < .001, SE = .10, 95% CI [.15, .54], but not thwarted belongingness, B = 0.14, p = .146; β = .14, p = .161, SE = .10, 95% CI [-.05, .33]. Additional models were examined using PTSD cluster scores for exploratory purposes. The results indicate that PTSD treatment reduces the perceived and objective burden of PTSD to decrease SI. Study findings support the importance of access to evidence-based care to treat PTSD and alleviate burdensomeness for suicide prevention.

Clinical outcomes of veterans affairs residential PTSD treatment for PTSD and depressive symptoms: 1-year follow-up outcomes and gender differences.

The long-term effectiveness of Department of Veterans Affairs (VA) residential treatment for posttraumatic stress disorder (PTSD), and how it may vary for men and women veterans, is unknown. This is the first national investigation of symptom change from admission, discharge, 4 months, and 1-year postdischarge from VA PTSD residential rehabilitation treatment programs (RRTPs). Participants included all veterans discharged from 40 VA PTSD RRTPs October 1, 2017-September 30, 2020 (n = 2,937; 14.3% women). Linear mixed models examined PTSD and depressive symptoms across time points; it was hypothesized that women veterans would experience greater symptom reduction during and after treatment. Overall, veterans reported large-sized reductions of PTSD symptoms at all time points (Cohen's d: discharge = 1.23, 4-month follow-up d = 0.97, 1-year follow-up d = 1.51). Treatment effects for depressive symptoms were large-sized at all time points (Cohen's d; discharge = 1.03, 4-month follow-up d = 0.94, 1-year follow-up d = 1.05). Women veterans showed greater improvement in PTSD and depressive symptom severity (p < .001) than men at discharge, but not at 4-month or 1-year follow-ups. Veterans reported significant reductions in PTSD and depressive symptoms, and treatment gains were maintained one year postdischarge. Women experienced greater benefit during, but not after, treatment. Results not only provide support for the effectiveness of VA residential treatment for PTSD but also highlight the continued need for strategies to maximize and maintain treatment gains.

"I wish people could come together like we have," patient and provider perspectives on VA residential PTSD treatment.

Although most posttraumatic stress disorder (PTSD) care in the Veterans health administration (VHA) is provided on an outpatient basis, the VHA has 40 residential rehabilitation treatment programs (RRTPs) designed to treat Veterans who require more intensive and closely monitored care. Unfortunately, the clinical outcomes of these programs are modest, and previous attempts to identify key drivers of outcomes have uncovered few modifiable factors. The present study, informed by the model of resources, life events and changes in psychological state, was designed to identify factors associated with treatment response among RRTP patients and providers. Semistructured interviews were conducted with 24 patients and 12 providers at three regional RRTPs, using interview guides based on the theoretical model. Data were analyzed using rapid analysis. Results showed that patients and providers agreed on several factors critical to RRTP success. These factors included the provision of evidence-based psychotherapy (EBP), support and understanding from fellow patients, and skill and support from providers. Patients and providers also noted the importance of psychological flexibility, openness, and willingness to change. Patients who experienced less symptom improvement over the course of treatment were more likely to report poor therapeutic alliance. These findings underscore the importance of continued emphasis on EBP delivery but also suggest that RRTPs might find additional ways to capitalize on the residential milieu to encourage engagement in treatment and a focus on therapeutic change.

Longitudinal profiles of sleep during residential PTSD treatment

We investigated longitudinal profiles of objectively measured sleep periods (SP) over the course of residential treatment for posttraumatic stress disorder (PTSD) in a cohort of U.S. male veterans. Participants (N = 190) slept on mattress-actigraphy systems in a Veterans Affairs (VA) residential PTSD program. The final sample included 4078 sleep periods. Latent class mixed model analyses were used to identify between-subject profiles in sleep period durations, controlling for daily medication intake, over the first fifty days of residency. Logistic regression was used to determine the association of pre-treatment characteristics with identified profiles. Three longitudinal profiles of sleep period characterized most of the sample: ‘stable’ (56%), ‘decreasing’ (35%), and ‘increasing’ (8%). Less severe pre-treatment PTSD avoidance symptoms predicted membership in the 'decreasing' class and increased depression symptoms were predictive of membership in the 'increasing' class. Nearly half of the sample reported a summary change of 1 h or more over the course of the initial 50-nights in the program. Future work is needed to identify how these profiles might drive inpatient treatment decisions regarding the provision of adjunctive sleep-focused treatment such as cognitive-behavioral treatment for insomnia or hypnotic medications.

Comparative effectiveness of evidence-based psychotherapies for PTSD delivered in VA residential PTSD treatment.

Cognitive Processing Therapy (CPT) and Prolonged Exposure (PE) are first-line treatments for posttraumatic stress disorder (PTSD). There have been few direct comparisons of CPT and PE intended to determine their comparative effectiveness, none of which have examined outcomes among military veterans receiving these treatments in a residential setting such as the Department of Veterans Affairs (VA) residential rehabilitation treatment programs (RRTPs). Such work is essential given that these veterans are among the most complex and severely symptomatic patients with PTSD treated in VA. In this study we compared changes in PTSD and depressive symptoms across admission, discharge, four months and 12 months following discharge among veterans who received CPT or PE within VA RRTPs. Using linear mixed models conducted on program evaluation data derived from the electronic medical record and follow-up surveys, we compared self-reported PTSD and depressive symptom outcomes among 1130 veterans with PTSD who were treated with individual CPT (n = 832, 73.5%) or PE (n = 297, 26.5%) in VA PTSD RRTPs in fiscal years 2018-2020. PTSD and depressive symptom severity did not significantly differ at any time points. The CPT and PE groups both showed large-sized reductions in PTSD (CPT d = 1.41, PE d = 1.51) and depression (CPT d = 1.01, PE d = 1.09) from baseline to 12-month follow-up. Outcomes for PE and CPT do not differ among a highly complex population of veterans with severe PTSD and several comorbid conditions that can make it difficult to engage in treatment.

The Functional Significance of a Novel Conceptualization of Intrusion Symptoms of PTSD

IntroductionIntrusion symptoms are a core defining feature of posttraumatic stress disorder (PTSD). It was recently proposed that intrusions may be comprised of two distinct underlying processes: internally-cued intrusions (e.g., memories), and externally-cued intrusions (e.g., reactions to one’s environment). Preliminary empirical evidence demonstrated superior fit of an 8-factor model of PTSD, separating intrusion symptoms into an in internally-cued and externally-cued symptom cluster over other factor models of PTSD. However, whether these two clusters are related differently with functional outcomes was not investigated previously.ObjectivesThis is the first study to examine the functional correlates of the internally-cued and externally-cued intrusion symptom clusters in PTSD to assess whether separating intrusion symptoms into these two clusters is of clinical and scientific relevance.MethodsParticipants included 7460 veterans discharged from 40 VA PTSD residential treatment programs (RRTPs) across the United States in fiscal years 2018 through 2020. Demographic data was collected using a self-report form during the admission process. Symptoms of PTSD, anxiety, depression, and emotional and physical functioning were assessed with the PTSD Checklist for DSM-5, the Patient Health Questionnaire-9, the Generalized Anxiety Disorder Questionnaire-7, and the corresponding subscales of the Short Form 12-item Health Survey, respectively. Latent network modeling was used to test the fit of the 8-factor model of PTSD. Structural equation modelling was used to investigate the associations between the factors of PTSD and the functional outcomes. All associations were adjusted for demographic characteristics, and standardized.ResultsThe 8-factor model, with separate intrusion factors, showed good model fit (CFI 0.965, RMSEA 0.045, χ2 2453.022, and P &lt;.001). Internally-cued intrusions were negatively associated with physical functioning and positively with emotional functioning. No relationship with depression or anxiety was found. In contrast, externally-cued intrusions were negatively associated with emotional functioning and positively associated with anxiety, but not related to physical functioning and depression.ConclusionsThis study provides initial support for the functional utility of distinguishing between internally- and externally-cued intrusions in veterans with PTSD. Consequently, researchers focusing on the biological underpinnings of intrusion symptoms (e.g., in imaging or genetic studies) should account for differences in the origin of the cue triggering intrusions. Our findings are of potential clinical relevance as they might help patients adapt their coping strategies for intrusions depending on whether they originate internally (e.g., thoughts) or externally (e.g., loud noises).Disclosure of InterestNone Declared

Clinical significance of novel 8-factor model of DSM-5 PTSD in national VA PTSD residential treatment data: Internally- v. externally-cued intrusions

BackgroundIntrusion symptoms are a core defining feature of posttraumatic stress disorder (PTSD). It was recently proposed that intrusions may be comprised of two distinct underlying processes: internally-cued intrusions (e.g., trauma-related memories), and externally-cued intrusions (e.g., reactivity to trauma-related cues in one's environment). This is the first study to examine the functional correlates of these two intrusion clusters. MethodsParticipants included 7460 veterans discharged from 40 Veterans Affairs PTSD residential programs across the United States in fiscal years 2018 through 2020. Latent network modeling and structural equation modeling were used to assess the fit of an 8-factor model of PTSD symptoms, which were assessed using the PTSD Checklist for DSM-5 (PCL-5) PTSD symptoms at admission, and its association with symptoms of depression and generalized anxiety, and emotional and physical functioning. ResultsThe 8-factor model, with separate intrusion factors, showed superior model fit to the DSM-5 4-factor, 5-factor dysphoric arousal, 6-factor anhedonia, and 7-factor hybrid models of PTSD. Internally-cued intrusions were uniquely associated with dysphoric arousal, decreased avoidance, and worse physical health functioning; whereas, externally-cued intrusions were uniquely associated with greater avoidance, anxious arousal, negative affect, increased generalized anxiety symptoms, and worse emotional functioning. LimitationsLimitations include the cross-sectional design and use of self-report measures. ConclusionsFindings provide initial support for the clinical utility of a novel 8-factor model of PCL-5 PTSD symptoms, which distinguishes internally- and externally-cued intrusions. These separate intrusion symptom clusters may offer greater specificity and utility in informing the prognosis of and tailored interventions for PTSD.

Impact of residential PTSD treatment on suicide risk in veterans.

In 2019, 17 veterans died by suicide every day. Various suicide prevention treatments have emerged, yet limited research has explored the impact of Post Traumatic Stress Disorder (PTSD) treatment on suicidal ideation and behaviors. This study examines the impact of Cognitive Processing Therapy (CPT) on suicidal ideation among veterans in three residential PTSD programs (women's, men's, and PTSD/Traumatic Brain Injury). Interview and self-report data were collected from veterans (n = 446) throughout treatment. Over 50% of veterans reported current suicidal ideation and a history of suicide attempts prior to treatment. Variables that predicted change in suicidal ideation included prior suicide attempt (β = 0.21, p = 0.022), change in CAPS-5 total score (β = 0.28, p = 0.038), employment status (β = -0.20, p = 0.035) and history of suicide attempt (β = 0.25, p = 0.009). Those without a previous suicide attempt made greater gains in CPT treatment than those with a previous suicide attempt. Following 7 weeks of CPT residential treatment, a decrease in PTSD symptoms was significantly associated with a reduction in suicidal ideation. Implications are that CPT can reduce suicide risk in a variety of Veteran cohorts with differing trauma types.

Comparative effectiveness of group v. individual trauma-focused treatment for posttraumatic stress disorder in veterans.

Cognitive processing therapy (CPT) and prolonged exposure (PE) delivered in an individual setting are efficacious and effective treatments for veterans with posttraumatic stress disorder (PTSD). Group CPT has been shown to be less efficacious than individual CPT, however, evidence regarding real-world effectiveness is limited. We conducted a retrospective, observational, comparative effectiveness study including veterans that received at least eight sessions of group CPT, individual CPT, or individual PE, and were discharged from PTSD residential treatment at the Department of Veterans Affairs between 1 October 2015, and 30 September 2020. PTSD symptom severity was assessed with the PTSD Checklist for DSM-5 (PCL-5) and treatments delivered in a group (CPT) or individual (CPT or PE) setting were compared at discharge and 4-month post-discharge follow-up. Of 6735 veterans, 3888 [653 women (17%), median (IQR) age 45 (35-55) years] received individual and 2847 [206 women (7.2%), median (IQR) age 42 (34-54)] received group therapy. At discharge, improvement in PTSD severity was statistically greater among those treated individually (mean difference on the PCL-5, 2.55 (95% CI 1.61-3.49); p = <0.001]. However, the difference was smaller than the minimal clinically important difference of 7.9 points. The groups did not differ significantly at 4-month follow-up [mean difference on the PCL-5, 0.37 (95% CI -0.86 to 1.60); p = 0.551]. Group CPT was associated with a slightly smaller reduction of PTSD symptom severity than individual CPT or PE in veterans at the end of residential treatment. There were no differences at 4-month follow-up.

Psychological comorbidity: Predictors of residential treatment response among U.S. service members with posttraumatic stress disorder.

Residential posttraumatic stress disorder (PTSD) research in military samples generally shows that in aggregate, PTSD symptoms significantly improve over the course of treatment but can remain at elevated levels following treatment. Identifying individuals who respond to residential treatment versus those who do not, including those who worsen, is critical given the extensive resources required for such programs. This study examined predictors of treatment response among 282 male service members who received treatment in a U.S. Department of Defense residential PTSD program. Using established criteria, service members were classified as improved, indeterminate (referent), or worsened in terms of self-reported PTSD symptoms. Multinomial logistic regression results showed that for PTSD symptoms, higher levels of pretreatment PTSD symptom severity were associated with significantly lower odds of being in the improved group, adjusted odds ratio (aOR) = 0.955, p = .018. In addition, service members who completed treatment were significantly more likely to be in the improved group, aOR = 2.488, p = .048. Longer average pretreatment nightly sleep duration, aOR = 1.157, p = .035, and more severe pretreatment depressive symptoms, aOR = 1.109, p = .014, were associated with significantly higher odds of being in the improved group. These findings reveal clinical characteristics better suited for residential PTSD treatment and highlight implications for comorbid conditions.

Comparing Veterans with Posttraumatic Stress Disorder Related to Military Sexual Trauma or Other Trauma Types: Baseline Characteristics and Residential Cognitive Processing Therapy Outcomes.

The Veterans Health Administration (VHA) has called for improved assessment and intervention for survivors of military sexual trauma (MST) to mitigate deleterious sequalae, including posttraumatic stress disorder (PTSD). Research on the impact of MST-related PTSD (MST-IT) on men is limited, and few studies have examined the differential effects of treatment across genders and MST-IT. Additionally, studies have utilized varying definitions of MST (e.g., sexual assault only vs. including sexual harassment), contributing to disparate outcomes across studies. Utilizing data from 343 veterans seeking residential cognitive processing therapy (CPT) for PTSD in VHA, this study examined the impact of MST-IT and gender on differences in demographic characteristics; pre-treatment severity of PTSD (overall and clusters), depression, and negative posttraumatic cognitions (NPCs); and post-treatment severity of these variables after accounting for pre-treatment severity. Results from 2x2 factorial ANOVAs found no differences in pre-treatment depression or overall PTSD by MST-IT, gender, or their interaction; however, MST-IT survivors presented with greater pre-treatment avoidance, global NPCs, and self-blame. Results from hierarchical linear regression models found only pre-treatment symptom severity significantly predicted post-treatment severity for overall PTSD and all NPCs. These findings suggest veteran survivors of MST-IT appear to benefit similarly from CPT delivered in a VHA residential PTSD program compared to veterans with other index traumas, regardless of gender. Although there were minimal post-treatment differences in PTSD and NPCs by MST-IT status and gender, residual symptoms related to negative cognitions and mood appear to differ across gender and MST-IT status. Specifically, in individuals without MST-IT, post-treatment PTSD symptoms of negative alterations in cognition and mood were higher in men than women. Moreover, women with MST-IT reported more symptoms of depression than both men with MST-IT and women without MST-IT. These findings suggest depressive symptoms decrease through residential PTSD treatment differentially by MST-IT status and gender and warrant further examination.

Residential PTSD treatment outcomes during cognitive processing therapy for veterans with and without recent histories of cannabis use.

Prior evidence has suggested that cannabis use is associated with greater posttraumatic stress disorder (PTSD) symptom severity and worse outcomes following trauma-focused treatment. However, lack of high-quality randomized studies necessitates the use of clinical data to clarify the relationship between cannabis use and PTSD treatment to help inform clinical practice. A total of 114 veterans completed cognitive processing therapy in a residential PTSD treatment program. Differences in treatment response between cannabis users and nonusers were evaluated for measures of PTSD, depression, and posttraumatic growth using analysis of covariance to control for pretreatment scores and other drug use. At baseline, cannabis users reported higher levels of PTSD symptom severity relative to nonusers but reported similar levels of depression and posttraumatic growth. Significant differences between groups in the amount of change were not observed on any of the measures from before to after treatment; however, the total sample reported significant improvements in all measures of interest. These results suggest that PTSD treatment outcomes for cannabis users may be similar to nonusers when use is stopped during treatment. Additional data are needed regarding whether outcomes remain similar at follow-up, whether cannabis users maintain abstinence after treatment, and the impact of resumed cannabis use on PTSD symptoms.

Anger and predictors of drop-out from PTSD treatment of veterans and first responders.

Drop-out is an important barrier in treating post-traumatic stress disorder (PTSD) with consequences that negatively impact clients, clinicians and mental health services as a whole. Anger is a common experience in people with PTSD and is more prevalent in military veterans. To date, no research has examined if anger may predict drop-out in military veterans or first responders. The present study aimed to determine the variables that predict drop-out among individuals receiving residential treatment for PTSD. Ninety-five military veterans and first responders completed pre-treatment measures of PTSD symptom severity, depression, anxiety, anger, and demographic variables. Logistic regression analyses were used to determine if these variables predicted drop-out from treatment or patterns of attendance. Female gender was predictive of drop-out. However, when analysed by occupation female gender was predictive of drop-out among first responders and younger age was predictive of drop-out in military participants. Anger, depression, anxiety and PTSD symptom severity were not predictive of drop-out in any of the analyses. No variables were found to predict attendance patterns (consistent or inconsistent) or early versus late drop-out from the programme. These results suggest that although anger is a relevant issue for treating PTSD, other factors may be more pertinent to drop-out, particularly in this sample. In contrast with other findings, female gender was predictive of drop-out in this study. This may indicate that in this sample, there are unique characteristics and possible interacting variables that warrant exploration in future research.
