Chronicity in posttraumatic stress disorder and predictors of the course of posttraumatic stress disorder among primary care patients

Effectiveness in routine care: trauma-focused treatment for PTSD

Objective: The efficacy of trauma-focused cognitive behaviour therapy (tf-CBT) has been well established in randomized controlled trials (RCTs). More research is needed to demonstrate the effectiveness of tf-CBT in routine clinical care settings.Method: Eighty-five patients (68 female) with a primary diagnosis of PTSD received tf-CBT at two German outpatient centres (Münster and Mannheim) between 2014 and 2016. Treatment was delivered mainly by therapists in training and treatment duration was based on symptom course. The treatment consisted of a preparation phase, a trauma-focused phase (comprising imaginal exposure, discrimination training, changing dysfunctional appraisals) and a phase of reclaiming-your-life assignments, and relapse prevention. In an intent-to-treat-analysis (ITT), linear mixed effects models were fitted for self-assessments of traumatic symptom severity using the PTSD Checklist for DSM-5 (PCL-5) and the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5). Potential moderators for treatment outcome, e.g. number of suicide attempts, were investigated.Results: The observed treatment effect was large for both the CAPS-5 (ITT: Cohen's d = 2.07, CI [1.62, 2.51]; completers d = 2.34, CI [1.84, 2.83]) and PCL-5 respectively (ITT: d = 2.02, CI [1.56, 2.48]; completers d = 2.15, CI [1.66, 2.64]), and remained stable six months and one-year post-treatment. N = 27 patients (31.48%) were defined as study dropout and of these, n = 12 (14.12%) dropped out of the study but completed treatment. None of the fixed-effect estimates for treatment predictors interacted significantly with the effect of time.Conclusions: Tf-CBT is well-tolerated and it can be effectively delivered in routine clinical care. Its large treatment effects underline the practicability and benefits of the approach. This trial demonstrates its broad applicability among individuals with diverse patterns of clinical characteristics and comorbidities.

Understanding emotion dysregulation in PTSD - GAD comorbidity

Posttraumatic stress disorder (PTSD) frequently co-occurs with myriad mood and anxiety disorders including generalized anxiety disorder (GAD). Despite this comorbidity's prevalence, mechanisms underlying the co-occurrence of PTSD and GAD remains understudied. An emotion dysregulation framework routinely is used to understand both PTSD and GAD but has not been applied to the PTSD-GAD comorbidity. Using MANOVA, the present study tested domains of emotion dysregulation (DERS) and of positive emotion regulation (AEQ) as differentiators of PTSD alone versus PTSD with GAD using pre-intervention data from a randomized controlled trial including 292 women with PTSD secondary to interpersonal violence. Five of six emotion dysregulation domains differentiated the two groups: fewer regulation strategies, nonacceptance of emotional responses, impulse control difficulties, lack of emotional awareness, and lack of emotional clarity were associated with comorbidity. Of three positive emotion regulation domains, participants with PTSD alone reported more positive emotionality than those with PTSD and GAD, and those with comorbid PTSD and GAD reported more negative affective interference than those with PTSD only. Rather than specific domains underlying unique presentations, findings indicate a general dysregulation factor, where PTSD-GAD comorbidity is supported by an overall higher level of emotion dysregulation as compared to PTSD alone.

The feasibility and acceptability of delivering a group trauma-focused intervention to children in care

OBJECTIVE

Young people in care (i.e., in the child welfare system) are a group who have often experienced very high rates of potentially traumatic events, including maltreatment. It is well-documented that they have high rates of trauma-related mental health difficulties, such as posttraumatic stress. To address the needs of the large number of young people who may benefit from support, scalable interventions are crucial. But also important is that they are effective and deliverable - particularly given the complexity of this group and services. We assessed a five-session group CBT-based intervention for PTSD. The primary goal was to understand core procedural and protocol uncertainties to address prior to a definitive trial.

METHODS

Participants were 34 10-17 year olds in care, with moderate to severe posttraumatic stress symptoms, and their caregiver. We ran seven groups (four online), delivered in social care and NHS-based mental health teams. Data were collected via pre-, post-, 3-month follow-up questionnaires and qualitative interviews.

RESULTS

Of the 34 participants allocated to the intervention, 27 (80%) attended at least three of the five sessions (most attended all). Caregiver attendance was lower (50%). There was generally good completion of assessment measures. Qualitatively, most participants were positive about the intervention, and many reported improvements in areas such as coping, sleep, and willingness to talk about experiences. However, there were important concerns about the lack of ongoing support, given this was a low-intensity intervention for a group who often had complex needs.

CONCLUSION

The intervention and research protocols were acceptable to most young people and carers. With modifications, a future definitive trial would likely be possible. However, key considerations include: how (and whether) to screen for PTSD; the trial design; and the option to embed high-intensity support (e.g., via assessing a stepped-care model).

To sleep or not to sleep, that is the question: A systematic review and meta-analysis on the effect of post-trauma sleep on intrusive memories of analog trauma

Distressing intrusive memories of a traumatic event are one of the hallmark symptoms of posttraumatic stress disorder. Thus, it is crucial to identify early interventions that prevent the occurrence of intrusive memories. Both, sleep and sleep deprivation have been discussed as such interventions, yet previous studies yielded contradicting effects. Our systematic review aims at evaluating existing evidence by means of traditional and individual participant data (IPD) meta-analyses to overcome power issues of sleep research. Until May 16th, 2022, six databases were searched for experimental analog studies examining the effect of post-trauma sleep versus wakefulness on intrusive memories. Nine studies were included in our traditional meta-analysis (8 in the IPD meta-analysis). Our analysis provided evidence for a small effect favoring sleep over wakefulness, log-ROM = 0.25, p < .001, suggesting that sleep is associated with a lower number of intrusions but unrelated to the occurrence of any versus no intrusions. We found no evidence for an effect of sleep on intrusion distress. Heterogeneity was low and certainty of evidence for our primary analysis was moderate. Our findings suggest that post-trauma sleep has the potential to be protective by reducing intrusion frequency. More research is needed to determine the impact following real-world trauma and the potential clinical significance.

MDMA-assisted therapy for posttraumatic stress disorder: A pooled analysis of ethnoracial differences in efficacy and safety from two Phase 2 open-label lead-in trials and a Phase 3 randomized, blinded placebo-controlled trial

BACKGROUND

Limited ethnoracial diversity in previous ±3,4-methylenedioxymethamphetamine-assisted therapy (MDMA-AT) trials for posttraumatic stress disorder (PTSD) has prompted questions concerning whether Black, Indigenous, and People of Color (BIPOC) also benefit from this treatment.

METHODS

Secondary analysis was conducted using a modified intent-to-treat sample pooled from two Phase 2 open-label trials and a Phase 3 randomized, blinded placebo-controlled trial to compare efficacy and safety of MDMA-AT for PTSD between BIPOC and non-Hispanic White participants. Four subgroups were of interest: MDMA-AT, BIPOC (n = 20); MDMA-AT, non-Hispanic White (n = 63); Placebo-assisted therapy (Placebo-AT), BIPOC (n = 17); and Placebo-AT, non-Hispanic White (n = 27). Planned comparisons tested subgroup differences in changes in Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) scores from baseline to primary endpoint, controlling for study type and baseline scores. Adverse events (AEs) on the day of (day 0) to 2 days post-dosing were reported for each subgroup.

RESULTS

In the MDMA-AT group, no significant ethnoracial difference in CAPS-5 change scores was observed. In the Placebo-AT group, BIPOC participants trended toward greater reductions in CAPS-5 scores than non-Hispanic Whites. Among non-Hispanic Whites, MDMA-AT was accompanied by significantly greater reductions in CAPS-5 scores than Placebo-AT. No treatment difference emerged among BIPOC participants. AEs were mostly rated as mild or moderate across subgroups.

CONCLUSIONS

These findings provide preliminary support for the efficacy and safety of MDMA-AT for treating PTSD across ethnoracial groups. There was also a trend toward greater efficacy with Placebo-AT among BIPOC participants. There was an imbalance in subgroups, highlighting the need for culturally responsive recruitment strategies to diversify future studies.

Course and Predictors of Posttraumatic Stress Disorder in the Canadian Armed Forces: A Nationally Representative, 16-Year Follow-up Study: Cours et prédicteurs du trouble de stress post-traumatique dans les Forces armées canadiennes: une étude de suivi de 16 ans nationalement représentative

OBJECTIVE

This study examined baseline risk and protective predictors and interim correlates of the persistence/recurrence, remission, and onset of posttraumatic stress disorder (PTSD) in a 16-year prospective, nationally representative sample of Canadian Forces members and veterans.

METHODS

The 2018 Canadian Armed Forces Members and Veterans Mental Health Follow-up Survey is a prospective study of 2,941 regular force service members and veterans who participated in the 2002 Canadian Community Health Survey on Mental Health and Wellbeing: Canadian Forces Supplement (n = 5,155; ages 15 to 64 years; response rate 68%). PTSD diagnoses in 2002 and 2018 were used to create 4 groups: (1) no lifetime, (2) remitted, (3) new onset, and (4) persistent/recurrent PTSD. Multinomial regressions were conducted to identify predictors of PTSD courses.

RESULTS

Female sex, being a junior noncommissioned member (vs. officer), and land (vs. air) operations in 2002 were associated with all PTSD courses relative to no lifetime PTSD (relative risk ratio [RRR] range: 1.28 to 3.65). After adjusting for sociodemographic variables, baseline predictors of all PTSD courses included lifetime mental disorder, history of mental health care utilization, all trauma type categories (deployment-associated, sexual, "other"), and the number of lifetime traumatic events (RRR range: 1.14 to 8.95). New ("since 2002") traumas, transitioning to veteran status, and alcohol dependence were mostly associated with the new onset and persistent/recurrent PTSD courses (RRR range: 1.79 to 4.31), while mental health care utilization and greater avoidance coping were associated with all PTSD courses (RRR range: 1.10 to 17.87). Protective factors for several PTSD courses at one or both time points included social support, social network size, and problem-focused coping (RRR range: 0.71 to 0.98).

CONCLUSIONS

This is the first population-based survey to examine the longitudinal course of PTSD in Canadian Forces members. Prevention and intervention programs focused on bolstering social support and active coping strategies as possible protective factors/correlates may help mitigate the development and persistence of PTSD.

Cognition and Other Predictors of Functional Disability Among Veterans With Mild Traumatic Brain Injury and Posttraumatic Stress Disorder

BACKGROUND

Limitations in everyday functioning are frequently reported by veterans with a history of mild traumatic brain injury (mTBI) and/or posttraumatic stress disorder (PTSD). Multiple factors are associated with functional disability among veterans, including depression, poor social support, cognition, and substance use. However, the degree to which these factors, particularly cognitive capacities, contribute to functional limitations remains unclear.

METHODS

We evaluated performance on tests of processing speed, executive functioning, attention, and memory as predictors of functioning on the World Health Organization Disability Assessment Scale (WHODAS) 2.0 in 288 veterans. Participants were placed in one of the following groups: PTSD-only, mTBI-only, mTBI + PTSD, and neither PTSD nor mTBI (deployed control group). Cognitive test performances were evaluated as predictors of WHODAS 2.0 functional ratings in regression models that included demographic variables and a range of mood, behavioral health, and postconcussive symptom ratings.

RESULTS

Multiple cognitive test performances predicted WHODAS 2.0 scores in the deployed control group, but they generally did not predict functioning in the clinical groups when accounting for demographics, mood, behavioral health, and postconcussive symptoms.

CONCLUSIONS

In veterans with mTBI and/or PTSD, cognitive test performances are less associated with everyday functioning than mood and postconcussive symptoms.

Posttraumatic stress disorder in African American and Latinx adults: Clinical course and the role of racial and ethnic discrimination

Research has suggested that African American and Latinx adults may develop posttraumatic stress disorder (PTSD) at higher rates than White adults, and that the clinical course of PTSD in these minority groups is poor. Factors that may contribute to higher prevalence and poorer outcome in these groups are sociocultural factors and racial stressors, such as experiences with discrimination. To date, however, no research has explored the relationship between experiences with discrimination and risk for PTSD, and very little research has examined the course of illness for PTSD in African American and Latinx samples. The present study examined these variables in the only longitudinal clinical sample of 139 Latinx and 152 African American adults with anxiety disorders, the Harvard/Brown Anxiety Research Project-Phase II. Over 5 years of follow-up, remission rates for African Americans and Latinx adults with PTSD in this sample were 0.35 and 0.15, respectively, and reported frequency of experiences with discrimination significantly predicted PTSD diagnostic status in this sample, but did not predict any other anxiety or mood disorder. These findings demonstrate the chronic course of PTSD in African American and Latinx adults, and highlight the important role that racial and ethnic discrimination may play in the development of PTSD among these populations. Implications for an increased focus on these sociocultural stressors in the assessment and treatment of PTSD in African American and Latinx individuals are discussed.

Refinement and Pilot Testing of a Brief, Early Intervention for PTSD and Alcohol Use Following Sexual Assault

Experiencing a sexual assault can have long-lasting negative consequences including development of posttraumatic stress disorder (PTSD) and alcohol misuse. Intervention provided in the initial weeks following assault can reduce the development of these chronic problems. This study describes the iterative treatment development process for refining a brief intervention targeting PTSD and alcohol misuse for women with recent sexual assault experiences. Experts, treatment providers, and patients provided feedback on the intervention materials and guided the refinement process. Based on principles of cognitive change, the final intervention consists of one in-person session and four coaching calls targeting beliefs about the assault and about drinking behavior. Initial feasibility and acceptability data are presented for patients enrolled in an open trial (N = 6). The intervention was rated as helpful, not distressing, and interesting by patients and all patients completed the entire treatment protocol. A large decrease in PTSD symptoms pre- to post-intervention was observed. A small effect on decreasing alcohol consequences also emerged, although drinks consumed per week showed a slight increase, not a decrease, over the course of the intervention. Applications of this intervention and next steps for testing efficacy are presented.

Multimorbidity among Veterans Diagnosed with PTSD in the Veterans Health Administration Nationally

Over 30% of veterans treated for psychiatric disorders in the Veterans Health Administration (VHA) are diagnosed with Post-Traumatic Stress Disorder (PTSD), with most receiving treatment for war-zone stress they experienced decades previously. We examined psychiatric multimorbidity among these patients and consider its implications for treatment and research. Using national VHA data from Fiscal Year 2012 on all veterans diagnosed with PTSD, we compared those with PTSD only to those with one, two, and three or more concurrent (non-substance use) psychiatric disorders. Comparisons of these four groups on sociodemographic characteristics, medical and substance use co-morbidities, health service use, and psychotropic prescription fills were conducted using bi-variate and ordinal logistic regression methods. Of 638,451 veterans diagnosed with PTSD in FY2012, only 29.8% had PTSD alone; 36.7% had one concurrent psychiatric diagnosis, 21.3% had two, and 12.2% had three or more. Anxiety disorder and major depressive disorder were the most common concurrent diagnoses. Veterans with higher levels of multimorbidity were younger, had greater likelihood of recent homelessness, substance use disorder, and diverse medical diagnoses, along with increased mental health and medical service use and greater psychotropic medication use. Psychiatric multimorbidity is highly prevalent among VHA patients diagnosed with PTSD, and may represent an underappreciated and poorly understood clinical complication that poses unique challenges to effective treatment. Clinical attention and both epidemiological and interventional research on multimorbidity in PTSD patients are needed in order to better understand and treat this common but understudied phenomenon.

Psychiatric Symptom Profiles Predict Functional Impairment

Objective: Mental illness often interferes with daily functioning and an individual's pattern of psychiatric signs and symptoms may predict risk of future disability. Understanding the linkage between psychiatric symptoms and impaired functioning is critical for accurate rehabilitation planning and legal assessment. Here, we investigated the stability of functional impairment measures over 18 months and their association with psychiatric symptoms. Moreover, we developed a clinical self-report measure that allows estimation of functional impairment levels over 18 month observation periods. Methods: Consecutively treated outpatients and daycare patients (N = 155) from several psychiatric units in Switzerland completed the Dissociative Experiences Scale, Somatoform Dissociation Questionnaire, Multidimensional Inventory for Dissociation, Beck Depression Inventory, Brief Symptom Inventory, and WHO Disability Assessment Schedule at baseline, 6, 12, and 18 month follow-up examinations. The association between symptoms functional impairment over time was investigated using longitudinal linear mixed models. Penalized regression was used to identify questionnaire items that best predicted functional impairment. Results: We found high stability in the extent of functional impairment over 18 months. Fear of negative evaluation, fatigue, concentration problems, negative alterations in mood, and dissociative symptoms showed the strongest association with functional impairment measures. The empirically derived scale for functional impairment prediction explained between 0.62 and 0.77 of the variance in disability across various life domains. Conclusion: Given the capability for somatic and mental symptoms associated with social anxiety, depression, and dissociation to predict future disability, these symptoms have strong potential for guiding rehabilitation planning and prognostic evaluation in insurance medicine. The Functional Impairment Prediction Scale may serve as a valuable, empirical-based extension in legal assessments of how work capacity is affected by psychological factors.

Dissociative symptoms mediate the relation between PTSD symptoms and functional impairment in a sample of military members, veterans, and first responders with PTSD

Background: Posttraumatic Stress Disorder (PTSD) is associated with significant functional impairment in important areas, including interpersonal relationships and occupational or educational roles. Preliminary evidence suggests that the dissociative subtype of PTSD (PTSD+DS), characterized by marked symptoms of depersonalization and derealization, is associated with increased functional impairment and disease severity, including among military members and veterans diagnosed with PTSD. Similarly, first responders (e.g. police, fire, paramedics) have also been found to experience dissociative symptoms. Despite these findings, little work has investigated whether dissociative symptoms are related to heightened functional impairment among these populations. Objective: We examined the relation between functional impairment and symptom level variables, including dissociative symptoms of depersonalization and derealization among military members, veterans, and first responders with probable PTSD. We further investigated the hypothesis that dissociative symptoms mediate the relation between PTSD symptomatology and functional impairment. Method: Eighty-one medical charts of inpatients at a residential PTSD treatment programme were accessed via retrospective review. Sixty-two were included in the present analyses. Comparison of means on symptom measures between first responders and military members/veterans were conducted, followed by correlational and mediation analyses. Results: Compared with first responders, military members and veterans showed higher levels of derealization, functional impairment, alexithymia, anxiety, and depression. Within the total sample, dissociative symptoms emerged as the strongest correlate of functional impairment and, among the dissociative symptom clusters, derealization symptoms demonstrated the strongest relation with impairment. Mediation analyses revealed that total dissociative symptoms and derealization symptoms significantly mediated the relation between PTSD symptoms and functional impairment. Conclusions: These findings highlight the importance of assessing and treating dissociative symptoms, consistent with the dissociative subtype of PTSD, among military members, veterans, and first responders with PTSD. Successful recovery on a functional and symptomatic level may necessitate treatment of dissociative symptoms, particularly derealization.

Predictors of remission from PTSD symptoms after sexual and non-sexual trauma in the community: A mediated survival-analytic approach

Epidemiological data on the chronicity of posttraumatic stress disorder (PTSD) symptoms in relation to trauma type and underlying pathways are rare. The current study explored how PTSD symptoms change over time across different trauma types and examined mediators of their persistence. A trauma-exposed community sample, whereof approximately one quarter met diagnostic criteria for PTSD, provided retrospective data on the duration of PTSD symptoms. Those who remitted and those who had not at the time of assessment were compared regarding worst trauma, symptom severity, comorbidity, demographic and treatment-seeking variables. Time to remission was estimated using Cox proportional hazard models including candidate predictors of remission. A mediated survival analysis was used to explore indirect pathways that explain trauma-specific differences in remission times. Both the full sample and PTSD subgroup were analyzed separately. Overall, lower socio-economic status, lifetime and childhood sexual trauma, symptom severity, comorbid depression and past treatment were associated with non- and longer remissions. PTSD avoidance symptoms and comorbid depression were found to mediate longer remission times after lifetime or childhood sexual trauma. Our findings provide insight into the mechanisms and complicating factors of remission from PTSD symptoms after trauma, which might have important implications for therapeutic interventions.

Recovery from DSM-IV post-traumatic stress disorder in the WHO World Mental Health surveys

BACKGROUND

Research on post-traumatic stress disorder (PTSD) course finds a substantial proportion of cases remit within 6 months, a majority within 2 years, and a substantial minority persists for many years. Results are inconsistent about pre-trauma predictors.

METHODS

The WHO World Mental Health surveys assessed lifetime DSM-IV PTSD presence-course after one randomly-selected trauma, allowing retrospective estimates of PTSD duration. Prior traumas, childhood adversities (CAs), and other lifetime DSM-IV mental disorders were examined as predictors using discrete-time person-month survival analysis among the 1575 respondents with lifetime PTSD.

RESULTS

20%, 27%, and 50% of cases recovered within 3, 6, and 24 months and 77% within 10 years (the longest duration allowing stable estimates). Time-related recall bias was found largely for recoveries after 24 months. Recovery was weakly related to most trauma types other than very low [odds-ratio (OR) 0.2-0.3] early-recovery (within 24 months) associated with purposefully injuring/torturing/killing and witnessing atrocities and very low later-recovery (25+ months) associated with being kidnapped. The significant ORs for prior traumas, CAs, and mental disorders were generally inconsistent between early- and later-recovery models. Cross-validated versions of final models nonetheless discriminated significantly between the 50% of respondents with highest and lowest predicted probabilities of both early-recovery (66-55% v. 43%) and later-recovery (75-68% v. 39%).

CONCLUSIONS

We found PTSD recovery trajectories similar to those in previous studies. The weak associations of pre-trauma factors with recovery, also consistent with previous studies, presumably are due to stronger influences of post-trauma factors.

Treatment of victims of trauma

Not all traumatic events cause post-traumatic stress disorder (PTSD), and people develop PTSD symptoms after events that do not seem to be overwhelmingly traumatic. In order to direct services appropriately, there is a need to distinguish time-limited post-traumatic symptoms and acute stress reactions (that may improve spontaneously without treatment or respond to discrete interventions) from PTSD, with its potentially more chronic pathway and possible long-term effects on the personality. In this article, we describe acute and chronic stress disorders and evidence about the most effective treatments.

Cognitive Behavioral Therapy Is Associated With Enhanced Cognitive Control Network Activity in Major Depression and Posttraumatic Stress Disorder

BACKGROUND

Both major depressive disorder (MDD) and posttraumatic stress disorder (PTSD) are characterized by depressive symptoms, abnormalities in brain regions important for cognitive control, and response to cognitive behavioral therapy (CBT). However, whether a common neural mechanism underlies CBT response across diagnoses is unknown.

METHODS

Brain activity during a cognitive control task was measured using functional magnetic resonance imaging in 104 participants: 28 patients with MDD, 53 patients with PTSD, and 23 healthy control subjects; depression and anxiety symptoms were determined on the same day. A patient subset (n = 31) entered manualized CBT and, along with controls (n = 19), was rescanned at 12 weeks. Linear mixed effects models assessed the relationship between depression and anxiety symptoms and brain activity before and after CBT.

RESULTS

At baseline, activation of the left dorsolateral prefrontal cortex was negatively correlated with Montgomery–Åsberg Depression Rating Scale scores across all participants; this brain–symptom association did not differ between MDD and PTSD. Following CBT treatment of patients, regions within the cognitive control network, including ventrolateral prefrontal cortex and dorsolateral prefrontal cortex, showed a significant increase in activity.

CONCLUSIONS

Our results suggest that dimensional abnormalities in the activation of cognitive control regions were associated primarily with symptoms of depression (with or without controlling for anxious arousal). Furthermore, following treatment with CBT, activation of cognitive control regions was similarly increased in both MDD and PTSD. These results accord with the Research Domain Criteria conceptualization of mental disorders and implicate improved cognitive control activation as a transdiagnostic mechanism for CBT treatment outcome.

Development and refinement of a clinician intervention to facilitate primary care patient use of the PTSD Coach app

Posttraumatic stress disorder (PTSD) is common and undertreated among Veterans Affairs (VA) primary care patients. A brief primary care intervention combining clinician support with a self-management mobile app (Clinician-Supported PTSD Coach, CS-PTSD Coach) may improve patient outcomes. This study developed and refined an intervention to provide clinician support to facilitate use of the PTSD Coach app and gathered VA provider and patient qualitative and quantitative feedback on CS-PTSD Coach to investigate preliminary acceptability and implementation barriers/facilitators. VA primary care providers and mental health leadership (N = 9) completed a survey and interview regarding implementation barriers and facilitators structured according to the Consolidated Framework for Implementation Research (CFIR). Clinicians who delivered CS-PTSD Coach (N = 3) and patients (N = 9) who received it provided feedback on the intervention and implementation process. CS-PTSD Coach has high provider and patient acceptability. Important implementation factors included that CS-PTSD Coach be compatible with the clinics' current practices, have low complexity to implement, be perceived to address patient needs, and have strong support from leadership. Diverse factors related to CS-PTSD Coach delivery facilitate implementation, provide an opportunity to problem-solve barriers, and improve integration of the intervention into primary care.

Web-Delivered CBT Reduces Heavy Drinking in OEF-OIF Veterans in Primary Care With Symptomatic Substance Use and PTSD

Veterans from conflicts such as the wars in Iraq and Afghanistan commonly return with behavioral health problems, including posttraumatic stress disorder (PTSD) and hazardous or harmful substance use. Unfortunately, many veterans experience significant barriers to receiving evidence-based treatment, including poor treatment motivation, concerns about stigma, and lack of access to appropriate care. To address this need, the current study developed and evaluated a web-based self-management intervention based on cognitive behavioral therapy (CBT), targeting PTSD symptoms and hazardous substance use in a group of symptomatic combat veterans enrolled in VA primary care. Veterans with PTSD/subthreshold PTSD and hazardous substance use were randomized to primary care treatment as usual (TAU; n = 81) or to TAU plus a web-based CBT intervention called Thinking Forward (n = 81). Thinking Forward consisted of 24 sections (approximately 20 minutes each), accessible over 12 weeks. Participants completed baseline and 4-, 8-, 12-, 16-, and 24-week follow-up assessments. Three primary outcomes of PTSD, alcohol and other drug use, and quality of life were examined. Significant treatment effects were found for heavy drinking, but not for PTSD or quality of life. The effect of the intervention on heavy drinking was mediated by intervening increases in coping, social support, self-efficacy, and hope for the future. These results demonstrate the promise of a web-based, self-management intervention for difficult-to-engage OEF/OIF veterans with behavioral health and substance use concerns.

Dimensional depression severity in women with major depression and post-traumatic stress disorder correlates with fronto-amygdalar hypoconnectivty

Depressive symptoms are common in multiple psychiatric disorders and are frequent sequelae of trauma. A dimensional conceptualization of depression suggests that symptoms should be associated with a continuum of deficits in specific neural circuits. However, most prior investigations of abnormalities in functional connectivity have typically focused on a single diagnostic category using hypothesis-driven seed-based analyses. Here, using a sample of 105 adult female participants from three diagnostic groups (healthy controls, n=17; major depression, n=38; and post-traumatic stress disorder, n=50), we examine the dimensional relationship between resting-state functional dysconnectivity and severity of depressive symptoms across diagnostic categories using a data-driven analysis (multivariate distance-based matrix regression). This connectome-wide analysis identified foci of dysconnectivity associated with depression severity in the bilateral amygdala. Follow-up seed analyses using subject-specific amygdala segmentations revealed that depression severity was associated with amygdalo-frontal hypo-connectivity in a network of regions including bilateral dorsolateral prefrontal cortex, anterior cingulate and anterior insula. In contrast, anxiety was associated with elevated connectivity between the amygdala and the ventromedial prefrontal cortex. Taken together, these results emphasize the centrality of the amygdala in the pathophysiology of depressive symptoms, and suggest that dissociable patterns of amygdalo-frontal dysconnectivity are a critical neurobiological feature across clinical diagnostic categories.

A Web-Based Self-Management Program for Recent Combat Veterans With PTSD and Substance Misuse: Program Development and Veteran Feedback

Combat veterans from the wars in Iraq and Afghanistan commonly experience posttraumatic stress disorder (PTSD) and substance use problems. In addition, these veterans often report significant barriers to receiving evidence-based mental health and substance use care, such as individual beliefs that treatment will be unhelpful, inconvenient, or that they should be able to handle their problems on their own. To increase access to treatment for this underserved population, a Web-based patient self-management program that teaches cognitive-behavioral therapy (CBT) skills to manage PTSD symptoms and substance misuse was developed. This paper describes and provides results from an iterative, multistage process for developing the Web-based program and seeks to inform clinicians in the field about the preferences of veterans for using a Web-based CBT program. Systematic feedback was gathered from (a) three expert clinicians in the field, (b) focus groups of combat veterans (n = 18), and (c) individual feedback sessions with combat veterans (n = 34). Clinician feedback led to the incorporation of motivational strategies to increase participant engagement and an optional module that guides written trauma exposure work. Focus group feedback guided the research team to frame the program in a strength-based approach and allows for maximum flexibility, adaptability, interactivity, and privacy for veterans. In individual feedback sessions, veterans generally found the program likable, easy to use, and relevant to their experiences; critiques of the program led to revised content meant to increase clarity and participant interest. Our findings provide specific guidance for clinicians who are interested in developing or providing technology-based treatment, including the need to gather feedback from an intervention's target audience when adapting a psychotherapeutic intervention and that the treatment must be highly interactive and private to engage clients.

Evidence Map of Yoga for Depression, Anxiety, and Posttraumatic Stress Disorder

BACKGROUND

This study describes evidence of yoga's effectiveness for depressive disorders, general anxiety disorder (GAD), panic disorder (PD), and posttraumatic stress disorder (PTSD) in adults. We also address adverse events associated with yoga.

METHODS

We searched multiple electronic databases for systematic reviews (SRs) published between 2008 and July 2014, randomized controlled trials (RCTs) not identified in eligible SRs, and ongoing RCTs registered with ClincalTrials.gov.

RESULTS

We identified 1 SR on depression, 1 for adverse events, and 3 addressing multiple conditions. The high-quality depression SR included 12 RCTs (n = 619) that showed improved short-term depressive symptoms (standardized mean difference, -0.69, 95% confidence interval, -0.99 to -0.39), but there was substantial variability (I2 = 86%) and a high risk of bias for 9 studies. Three SRs addressing multiple conditions identified 4 nonrandomized studies (n = 174) for GAD/PD and 1 RCT (n = 8) and 2 nonrandomized studies (n = 22) for PTSD. We separately found 1 RCT (n = 13) for GAD and 2 RCTs (n = 102) for PTSD. Collectively, these studies were inconclusive for the effectiveness of yoga in treating GAD/PD and PTSD. The high-quality SR for adverse events included 37 primary reports (n = 76) in which inversion postures were most often implicated. We found 5 ongoing trials (3 for PTSD).

CONCLUSIONS

Yoga may improve short-term depressive symptoms, but evidence for GAD, PD, and PTSD remain inconclusive.

Posttraumatic stress disorder in African Americans: a two year follow-up study

The present study was a prospective, naturalistic, longitudinal investigation of the two year course of posttraumatic stress disorder (PTSD) in a sample of African Americans with anxiety disorders. The study objectives were to examine the two year course of PTSD and to evaluate differences between African Americans with PTSD and anxiety disorders and African Americans with anxiety disorders but no PTSD with regard to comorbidity, psychosocial impairment, physical and emotional functioning, and treatment participation. The participants were 67 African Americans with PTSD and 98 African Americans without PTSD (mean age 41.5 years, 67.3% female). Individuals with PTSD were more likely to have higher comorbidity, lower functioning, and they were less likely to seek treatment than those with other anxiety disorders but no PTSD. The rate of recovery from PTSD over two years was 0.10 and recovery from comorbid Major Depressive Disorder was 0.55. PTSD appears to be persistent over time in this population. The rates of recovery were lower than what has been reported in previous longitudinal studies with predominantly non-Latino Whites. It is imperative to examine barriers to treatment and factors related to treatment engagement for this population.

Routine versus ad hoc screening for acute stress following injury: who would benefit and what are the opportunities for prevention

Background

Screening for acute stress is not part of routine trauma care owing in part to high variability of acute stress symptoms in identifying later onset of posttraumatic stress disorder (PTSD). The objective of this pilot study was to assess the sensitivity, specificity, and power to predict onset of PTSD symptoms at 1 and 4 months using a routine screening program in comparison to current ad hoc referral practice.

Methods

Prospective cross-sectional observational study of a sample of hospitalized trauma patients over a four-month period from a level-I hospital in Canada. Baseline assessments of acute stress (ASD) and subsyndromal ASD (SASD) were measured using the Stanford Acute Stress Reaction Questionnaire (SASRQ). In-hospital psychiatric consultations were identified from patient discharge summaries. PTSD symptoms were measured using the PTSD Checklist-Specific (PCL-S). Post-discharge health status and health services utilization surveys were also collected.

Results

Routine screening using the ASD (0.43) and SASD (0.64) diagnoses were more sensitive to PTSD symptoms at one month in comparison to ad hoc referral (0.14) and also at four months (0.17, 0.33 versus 0.17). Ad hoc referral had greater positive predictive power in identifying PTSD caseness at 1 month (0.50) in comparison to the ASD (0.46) and SASD (0.43) diagnoses and also at 4 months (0.67 versus 0.25 and 0.29).

Conclusions

Ad hoc psychiatric referral process for acute stress is a more conservative approach than employing routine screening for identifying persons who are at risk of psychological morbidity following injury. Despite known limitations of available measures, routine patient screening would increase identification of trauma survivors at risk of mental health sequelae and better position trauma centers to respond to the circumstances that affect mental health during recovery.

Posttraumatic stress disorder in survivors of acute lung injury: evaluating the Impact of Event Scale-Revised

BACKGROUND

Survivors of acute lung injury (ALI) and other critical illnesses often experience substantial posttraumatic stress disorder (PTSD) symptoms. However, most questionnaires have not been validated against a PTSD diagnostic reference standard in this patient population. Hence, in the current study of survivors of ALI, we evaluated the Impact of Events Scale-Revised (IES-R), a questionnaire measure of PTSD symptoms, against the Clinician-Administered PTSD Scale (CAPS), the current state-of-the-art PTSD diagnostic reference standard, which also provides a quantitative assessment of PTSD symptoms.

METHODS

We evaluated the IES-R questionnaire vs the CAPS diagnostic interview in 60 of 77 consecutively recruited survivors of ALI from two prospective cohort studies of patients 1 to 5 years after ALI.

RESULTS

The IES-R total score (range: 0.0-3.2) and the CAPS total severity score (range: 0-70) were strongly related (Pearson r=0.80, Spearman ρ=0.69). Using CAPS data, eight of the 60 patients (13%) had PTSD at the time of assessment, and an additional eight patients had partial PTSD (total prevalence, 27%). In a receiver operating characteristics curve analysis with CAPS PTSD or partial PTSD as criterion variables, the area under the curve ranged from 95% (95% CI, 88%-100%) to 97% (95% CI, 92%-100%). At an IES-R threshold of 1.6, with the same criterion variables, sensitivities ranged from 80% to 100%, specificities 85% to 91%, positive predictive values 50% to 75%, negative predictive values 93% to 100%, positive likelihood ratios 6.5 to 9.0, negative likelihood ratios 0.0 to 0.2, and efficiencies 87% to 90%.

CONCLUSIONS

The IES-R appears to be an excellent brief PTSD symptom measure and screening tool in ALI survivors.

Predictors of the long-term course of comorbid PTSD: a naturalistic prospective study

OBJECTIVES

The study examined the long-term course of posttraumatic stress disorder (PTSD) by analyzing rates of recurrence and the predictive value of comorbid psychiatric disorders and psychosocial functioning.

METHODS

This study is based on diagnostic assessments administered at intake and subsequent follow-up interviews over a period of 15 years in a sample of 90 anxiety-disordered patients with comorbid PTSD who participated in the Harvard Brown Anxiety Research project (HARP). Kaplan-Meier life table analysis revealed a 0.20 probability of full remission during the 15 years of follow-up.

RESULTS

Latent growth model (LGM) analysis revealed that the number of trauma exposures was a predictor of a worse course of PTSD but only during some intervals of the 15-year follow-up. Subjects with full social phobia were more likely to experience worsening of PTSD over time in comparison with subjects with less severe social phobia. Role functioning in the areas of household and employment was a significant predictor of a declining course of PTSD.

CONCLUSIONS

These findings revealed the dynamic nature of the predictive value of traumatic experiences, the deleterious effect of social phobia and the long term effect of psychosocial functioning on the course of PTSD. Implications for treatment planning and development of interventions for PTSD are discussed.

Analysis of the longitudinal course of PTSD in 716 survivors of 10 disasters

PURPOSE

Identification of consistent predictors of the temporal course of PTSD has been hampered by non-uniform definitions of onset and remission. Onset and remission of PTSD based on different definitions were examined in a large database of systematically assessed disaster survivors.

METHODS

Directly exposed survivors of 10 disasters were studied within approximately 3 months of the disasters and again 1-3 years later, using consistent methods including full diagnostic assessment, allowing aggregation of data from different disasters into a unified database of 716 survivors.

RESULTS

Application of existing definitions of PTSD onset and remission uncovered problems with definitions based on diagnostic threshold as well as onset/remission of symptoms. Few predictors of timing of onset and PTSD remission were identified. Regardless, PTSD symptom group C was found to be pivotal to processes involved in both onset and remission of the disorder.

CONCLUSIONS

Research findings related to the onset and remission of PTSD are highly dependent on the definition used. Both symptom-based and diagnostic threshold-based definitions are problematic. Definitions of the onset and remission of PTSD might be more effectively based on the onset and remission of group C symptoms.

Remission from post-traumatic stress disorder in the general population

BACKGROUND

Few studies have focused on post-traumatic stress disorder (PTSD) remission in the population, none have modelled remission beyond age 54 years and none have explored in detail the correlates of remission from PTSD. This study examined trauma experience, symptom severity, co-morbidity, service use and time to PTSD remission in a large population sample.

METHOD

Data came from respondents (n=8841) of the 2007 Australian National Survey of Mental Health and Wellbeing (NSMHWB). A modified version of the World Health Organization's World Mental Health Composite International Diagnostic Interview (WMH-CIDI) was used to determine the presence and age of onset of DSM-IV PTSD and other mental and substance use disorders, type, age, and number of lifetime traumas, severity of re-experiencing, avoidance and hypervigilance symptoms and presence and timing of service use.

RESULTS

Projected lifetime remission rate was 92% and median time to remission was 14 years. Those who experienced childhood trauma, interpersonal violence, severe symptoms or a secondary anxiety or affective disorder were less likely to remit from PTSD and reported longer median times to remission compared to those with other trauma experiences, less severe symptoms or no co-morbidity.

CONCLUSIONS

Although most people in the population with PTSD eventually remit, a significant minority report symptoms decades after onset. Those who experience childhood trauma or interpersonal violence should be a high priority for intervention.

Remission of PTSD after victims of intimate partner violence leave a shelter

Intimate partner violence (IPV) is a significant public health problem associated with high rates of posttraumatic stress disorder (PTSD). Few longitudinal studies have investigated IPV-related PTSD and we know of only 1 longitudinal study to date that has explored IPV-related PTSD in residents of battered women's shelters. The current report describes a prospective study of IPV-related PTSD in an initial sample of 147 residents of battered women's shelters. Baseline correlates of remission of IPV-related PTSD (i.e., PTSD and IPV severity, loss of personal and social resources, cessation of abuse, reunion with abuser, and length of shelter stay) over a 6-month follow-up period were investigated. Although findings are consistent with prior research suggesting a natural recovery of PTSD in IPV-victims, they also show that a significant number (46.8%) of women exhibit chronic PTSD. Participants whose PTSD remitted over follow-up had at baseline less severe IPV-related PTSD (partial η(2) = .104) and fewer loss of personal and social resources (partial η(2) = .095), and were less likely to reunite with their abuser after leaving the shelter than participants with chronic PTSD (3.3% and 22.4%, respectively). Clinical implications and limitations of findings are discussed.

Yield of practice-based depression screening in VA primary care settings

BACKGROUND

Many patients who should be treated for depression are missed without effective routine screening in primary care (PC) settings. Yearly depression screening by PC staff is mandated in the VA, yet little is known about the expected yield from such screening when administered on a practice-wide basis.

OBJECTIVE

We characterized the yield of practice-based screening in diverse PC settings, as well as the care needs of those assessed as having depression.

DESIGN

Baseline enrollees in a group randomized trial of implementation of collaborative care for depression.

PARTICIPANTS

Randomly sampled patients with a scheduled PC appointment in ten VA primary care clinics spanning five states.

MEASUREMENTS

PHQ-2 screening followed by the full PHQ-9 for screen positives, with standardized sociodemographic and health status questions.

RESULTS

Practice-based screening of 10,929 patients yielded 20.1% positive screens, 60% of whom were assessed as having probable major depression based on the PHQ-9 (11.8% of all screens) (n = 1,313). In total, 761 patients with probable major depression completed the baseline assessment. Comorbid mental illnesses (e.g., anxiety, PTSD) were highly prevalent. Medical comorbidities were substantial, including chronic lung disease, pneumonia, diabetes, heart attack, heart failure, cancer and stroke. Nearly one-third of the depressed PC patients reported recent suicidal ideation (based on the PHQ-9). Sexual dysfunction was also common (73.3%), being both longstanding (95.1% with onset >6 months) and frequently undiscussed and untreated (46.7% discussed with any health care provider in past 6 months).

CONCLUSIONS

Practice-wide survey-based depression screening yielded more than twice the positive-screen rate demonstrated through chart-based VA performance measures. The substantial level of comorbid physical and mental illness among PC patients precludes solo management by either PC or mental health (MH) specialists. PC practice- and provider-level guideline adherence is problematic without systems-level solutions supporting adequate MH assessment, PC treatment and, when needed, appropriate MH referral.

Disorder of extreme stress not otherwise specified (DESNOS) in Croatian war veterans with posttraumatic stress disorder: case-control study

Aim

To determine the presence of disorder of extreme stress not otherwise specified (DESNOS) in Croatian war veterans who suffer from combat-related posttraumatic stress disorder (PTSD).

Methods

The research included 247 veterans of the 1991-1995 war in Croatia who suffered from PTSD and were psychiatrically examined at four clinical centers in Croatia during a month in 2008. It was based on the following self-assessment instruments: The Harvard Trauma Questionnaire (HTQ): Croatian Version, the Structured Interview for Disorder of Extreme Stress (SIDES-SR), and the Mini International Neuropsychiatric Interview (MINI)

Results

Based on the SIDES-SR results, we formed two groups of participants: the group with PTSD (N = 140) and the group with both PTSD and DESNOS (N = 107). Forty three percent of participants met the criteria for DESNOS. There was a significant difference in the intensity of posttraumatic symptoms between the group with both PTSD and DESNOS and the group with PTSD only (U = 3733.5, P = 0.001). Respondents who suffered from both PTSD and DESNOS also reported a significantly larger number of comorbid mental disorders (U = 1123.5, P = 0.049) and twice more frequently reported comorbid depression with melancholic features (OR = 2.109, P = 0.043), social phobia (OR = 2.137, P = 0.036), or panic disorder (OR = 2.208, P = 0.015).

Conclusion

Our results demonstrate that PTSD and DESNOS can occur in comorbidity, which is in contrast with the ICD-10 criteria. A greater intensity of symptoms and a more frequent comorbidity with other psychiatric disorders, especially depression, panic disorder, and social phobia require additional therapy interventions in the treatment processes.

The current state of intervention research for posttraumatic stress disorder within the primary care setting

Posttraumatic Stress Disorder (PTSD) is common among primary care patients and is associated with significant functional impairment, physical health concerns, and mental health comorbidities. Significant barriers to receiving adequate treatment often exist for primary care patients with PTSD. Mental health professionals operating as part of the primary care team have the potential to provide effective brief intervention services. While good PTSD screening and assessment measures are available for the primary care setting, there are currently no empirically supported primary care-based brief interventions for PTSD. This article reviews early research on the development and testing of primary care-based PTSD treatments and also reviews other brief PTSD interventions (i.e., telehealth and early intervention) that could be adapted to the primary care setting. Cognitive and behavioral therapies currently have the strongest evidence base for establishing an empirically supported brief intervention for PTSD in primary care. Recommendations are made for future research and clinical practice.

A 5-year longitudinal study of posttraumatic stress disorder in primary care patients

Little is known about the clinical course of posttraumatic stress disorder (PTSD) and the clinical predictors of its recovery in primary care patients. We examined 5 years of follow-up of PTSD symptoms using rates of recovery and recurrence, and the predictive value of comorbid mental disorders, treatment participation and psychosocial functioning, on PTSD recovery. We examined 199 participants with PTSD diagnoses, from the Primary Care Anxiety Disorder Project. We found that the course of PTSD in a sample of primary care patients is chronic. Survival analysis revealed that the likelihood of PTSD recovery was 38.0% and of recurrence it was 29.5%. Cox regression analyses indicated that baseline clinical variables did not have a significant relationship with probability of PTSD recovery. However, time-varying models showed that the course of psychosocial impairment was a significant predictor of the likelihood of recovery from PTSD. Findings provide initial empirical support for treatment approaches that focus on psychosocial functioning to reduce PTSD symptoms.

The 10-year course of PTSD in borderline patients and axis II comparison subjects

OBJECTIVE

The first objective is to detail the prevalence of post-traumatic stress disorder (PTSD) over a decade of follow-up for those in both study groups. The second is to determine time-to-remission, recurrence, and new onset of PTSD, and the third is to assess the relationship between sexual adversity and the likelihood of remission and recurrence of PTSD.

METHOD

The SCID I was administered to 290 borderline in-patients and 72 axis II comparison subjects during their index admission and re-administered at five contiguous 2-year follow-up periods.

RESULTS

The prevalence of PTSD declined significantly over time for patients with borderline personality (BPD) (61%). Over 85% of borderline patients meeting criteria for PTSD at baseline experienced a remission by the time of the 10-year follow-up. Recurrences (40%) and new onsets (27%) were less common. A childhood history of sexual abuse significantly decreased the likelihood of remission from PTSD, and an adult history of sexual assault significantly increased the likelihood of a recurrence of PTSD.

CONCLUSION

Taken together, the results of this study suggest that PTSD is not a chronic disorder for the majority of borderline patients. They also suggest a strong relationship between sexual adversity and the course of PTSD among patients with BPD.

Alcohol Use, Problems, and the Course of Posttraumatic Stress Disorder: A Prospective Study of Female Crime Victims

OBJECTIVE

This study examines whether alcohol use disorder status and consequences of drinking moderate the course of PTSD over the first 6 months following trauma exposure in a sample of female victims of interpersonal violence.

METHODS

Female sexual and physical assault victims (n = 64) were recruited through police, hospital, and victim service agencies. Women completed structured clinical interviews and self-report measures within the first five weeks, three months, and six months post-trauma with 73% retention across all three time points (n = 47). Analyses were conducted using Hierarchical Linear Modeling using alcohol abuse/dependence, peak alcohol use, and consequences during the 30 days prior to assault as moderators of the course of PTSD over time.

RESULTS

Women with alcohol use disorder at baseline had lower initial PTSD symptoms but also less symptom recovery over time than women without alcohol use disorder. This pattern of results was also found for those with high negative drinking consequences during the month prior to the assault. Baseline alcohol use was not found to significantly moderate PTSD course over the 6 months.

CONCLUSIONS

Findings suggest that negative consequences associated with alcohol use may be a risk factor for PTSD. Incorporating assessment of drinking problems for women presenting early post-trauma may be useful for identifying PTSD risk.

Considering PTSD for DSM-5

This is a review of the relevant empirical literature concerning the DSM-IV-TR diagnostic criteria for PTSD. Most of this work has focused on Criteria A1 and A2, the two components of the A (Stressor) Criterion. With regard to A1, the review considers: (a) whether A1 is etiologically or temporally related to the PTSD symptoms; (b) whether it is possible to distinguish "traumatic" from "non-traumatic" stressors; and (c) whether A1 should be eliminated from DSM-5. Empirical literature regarding the utility of the A2 criterion indicates that there is little support for keeping the A2 criterion in DSM-5. The B (reexperiencing), C (avoidance/numbing) and D (hyperarousal) criteria are also reviewed. Confirmatory factor analyses suggest that the latent structure of PTSD appears to consist of four distinct symptom clusters rather than the three-cluster structure found in DSM-IV. It has also been shown that in addition to the fear-based symptoms emphasized in DSM-IV, traumatic exposure is also followed by dysphoric, anhedonic symptoms, aggressive/externalizing symptoms, guilt/shame symptoms, dissociative symptoms, and negative appraisals about oneself and the world. A new set of diagnostic criteria is proposed for DSM-5 that: (a) attempts to sharpen the A1 criterion; (b) eliminates the A2 criterion; (c) proposes four rather than three symptom clusters; and (d) expands the scope of the B-E criteria beyond a fear-based context. The final sections of this review consider: (a) partial/subsyndromal PTSD; (b) disorders of extreme stress not otherwise specified (DESNOS)/complex PTSD; (c) cross- cultural factors; (d) developmental factors; and (e) subtypes of PTSD.

EMDR for Survivors of Life-Threatening Cardiac Events: Results of a Pilot Study

This pilot study evaluated the effectiveness of eye movement desensitization and reprocessing (EMDR) in treating posttraumatic stress disorder (PTSD) symptoms and concomitant depressive and anxiety symptoms in survivors of life-threatening cardiac events. Forty-two patients undergoing cardiac rehabilitation who (a) qualified for the PTSD criterion “A” in relation to a cardiac event and (b) presented clinically significant PTSD symptoms were randomized to a 4-week treatment of EMDR or imaginal exposure (IE). Data were gathered on PTSD, anxiety, and depressive symptoms at pretreatment, posttreatment, and 6-month follow-up. EMDR was effective in reducing PTSD, depressive, and anxiety symptoms and performed significantly better than IE for all variables. These findings provide preliminary support for EMDR as an effective treatment for the symptoms of PTSD, depression, and anxiety that can follow a life-threatening cardiac event.

Post-traumatic stress disorder screening test performance in civilian primary care

PURPOSE

we determined the test performance characteristics of four brief post-traumatic stress disorder (PTSD) screening tests in a civilian primary care setting.

METHODS

this was a cross-sectional cohort study of adults attending a family medicine residency training clinic in the southeastern USA. Four hundred and eleven participants completed a structured telephone interview that followed an index clinic visit. Screening tests included: PTSD Symptom Checklist-Civilian Version (17 items), SPAN (four items), Breslau's scale (seven items) and Primary Care PTSD screen (PC-PTSD) (four items). A modified Clinician-Administered PTSD Scale was used to determine past month PTSD for comparison. Receiver operating characteristic analysis based on area under the curve (AUC) was used to assess diagnostic efficiency (>0.80 desired). Cut-off scores were selected to yield optimal sensitivity and specificity (>80%).

RESULTS

past month PTSD was substantial (women = 35.8% and men = 20.0%; P < 0.01). AUC values were PTSD Symptom Checklist (PCL) (0.897), SPAN (0.806), Breslau's scale (0.886) and PC-PTSD (0.885). Optimal cut-scores yielded the following sensitivities and specificities: PCL (80.0% and 80.7%; cut-off = 43), SPAN (75.9% and 71.6%; cut-off = 3), Breslau's scale (84.5% and 76.4%; cut-off = 4) and PC-PTSD (85.1% and 82.0%; cut-off = 3). Overall and gender-specific screening test performances were explored.

CONCLUSIONS

results confirm: (i) PTSD was common, especially among women; (ii) all four PTSD screening tests were diagnostically adequate; (iii) Two of four PTSD screening tests showed adequate sensitivity and specificity (>80%) and (iv) The PC-PTSD screening test (four items) appeared to be the best single screening test. There are few studies to establish the utility of PTSD screening tests within civilian primary care.

Heterogeneity in the course of posttraumatic stress disorder: trajectories of symptomatology

Unconditional and conditional trajectories of posttraumatic stress disorder (PTSD) symptomatology were examined using a sample of U.S. soldiers deployed on a NATO-led peacekeeping mission to Kosovo. Data were collected at 4 time points, ranging from the weeks leading up to deployment to 9-months post deployment. Latent class growth analysis revealed 4 unique symptom trajectories: resilience, recovery, delayed, and unrealized anxiety. Variables identified as significant predictors of trajectory class included previous traumatic events, combat exposure, peacekeeping daily hassles, depression, alcohol use, aggressive behavior, stress reactivity, and military rank. Results from this study add to the literature detailing the variability in PTSD course, as well as to the literature pertaining to predictors of PTSD onset and course.

Symptoms of acute posttraumatic stress disorder in prostate cancer patients following radical prostatectomy

Psychological morbidity is increasingly reported in cancer survivors. The authors' objective was to determine the presence of acute posttraumatic stress disorder (PTSD) symptoms in prostate cancer (PC) patients following radical prostatectomy. Fifteen patients who underwent radical prostatectomy for localized prostate cancer were assessed for the presence of PTSD-related symptoms by completing the Davidson Trauma Scale (DTS), a month following the procedure. A group of 20 patients who underwent surgery for benign prostate hyperplasia (BPH) served as the control group. PTSD total scores were significantly higher in PC patients when compared with BPH patients, whose PTSD scores did not differ from those reported in the general population (32.6 ± 18.5 vs. 11.3 ± 9.7, p = .001). PTSD did not vary among PC patients when adjusted for educational status. PTSD symptoms are common among patients undergoing radical prostatectomy and independent of their educational level. Research investigating these aspects of posttreatment psychological adjustment is needed for developing well-targeted psychological interventions.

A factor analytic comparison of five models of PTSD symptoms

This study examined the factor structure of PTSD symptoms in a sample of college students (n=344) reporting exposure to a range of traumatic events. The sample was randomly split and an exploratory factor analysis was conducted with half of the sample. The factor structure obtained in the exploratory analysis was evaluated against three other models using confirmatory factor analysis utilizing the second half of the sample. This series of factor analyses identified and confirmed a three-factor symptom structure consisting of intrusion/avoidance, dysphoria, and hyperarousal clusters. These results add to the body of literature which has found that PTSD includes a cluster of symptoms shared with other diagnoses (dysphoria) and a more specific factor related directly to the effects of encountering traumatic experiences.

The development and psychometric evaluation of the emotional reactivity and numbing scale

Recent research has highlighted the role of hyperresponsivity and numbing of emotions in posttraumatic stress disorder. Preliminary research suggests that emotional numbing symptoms impact the development, maintenance, and treatment of posttraumatic stress disorder. However, research in this area has been hindered, in part, due to the absence of a psychometrically sound, conceptually based measure of emotional numbing. The present study examined the psychometric properties of the Emotional Reactivity and Numbing Scale in a sample of 92 trauma-exposed men and women veterans. Results provide preliminary support for the internal consistency, test-retest reliability, convergent, and discriminant validity of the measure. Implications for future research are discussed.

Cerebral blood flow changes during retrieval of traumatic memories before and after psychotherapy: a SPECT study

BACKGROUND

Traumatic memory is a key symptom in psychological trauma victims and may remain vivid for several years. Psychotherapy has shown that neither the psychopathological signs of trauma nor the expression of traumatic memories are static over time. However, few studies have investigated the neural substrates of psychotherapy-related symptom changes.

METHOD

We studied 16 subthreshold post-traumatic stress disorder (PTSD) subjects by using a script-driven symptom provocation paradigm adapted for single photon emission computed tomography (SPECT) that was read aloud during traumatic memory retrieval both before and after exposure-based and cognitive restructuring therapy. Their neural activity levels were compared with a control group comprising 11 waiting-list subthreshold PTSD patients, who were age- and profile-matched with the psychotherapy group.

RESULTS

Significantly higher activity was observed in the parietal lobes, left hippocampus, thalamus and left prefrontal cortex during memory retrieval after psychotherapy. Positive correlations were found between activity changes in the left prefrontal cortex and left thalamus, and also between the left prefrontal cortex and left parietal lobe.

CONCLUSIONS

Neural mechanisms involved in subthreshold PTSD may share neural similarities with those underlying the fragmented and non-verbal nature of traumatic memories in full PTSD. Moreover, psychotherapy may influence the development of a narrative pattern overlaying the declarative memory neural substrates.

Adult Post-Traumatic Stress Disorder: Screening and Treating in Primary Care

Trauma and post-traumatic stress disorder (PTSD) affect patients' physical health and daily functioning. Primary care physicians should remember to screen for trauma history and symptoms of PTSD when patients present with somatization, chronic pain, or other unexplained symptoms. Perceived loss of control, including physical examinations and procedures, may be frightening, and physicians should ask the patient's permission before touching them. Patients who have PTSD benefit from treatment, including both psychopharmacology (primarily selective serotonin reuptake inhibitors) and psychotherapy. Finally, hearing patients' stories of trauma and exposure to very sick patients can be traumatizing for physicians, who are encouraged to actively engage in self-care activities.

PTSD in urban primary care: high prevalence and low physician recognition

BACKGROUND

Posttraumatic stress disorder (PTSD) is associated with medical and psychological morbidity. The prevalence of PTSD in urban primary care has not been well described.

OBJECTIVE

To measure the prevalence of PTSD in primary care patients overall and among those with selected conditions (chronic pain, depression, anxiety, heavy drinking, substance dependence (SD), irritable bowel syndrome (IBS), and immigrant status).

DESIGN

Cross-sectional study.

PARTICIPANTS

English-speaking patients aged 18-65 years old, awaiting primary care appointments in an urban academic medical center, were eligible for enrollment to determine PTSD prevalence (N = 509). Additional eligible participants (n = 98) with IBS or SD were subsequently enrolled.

MEASUREMENTS

PTSD (past year) and trauma exposure were measured with Composite International Diagnostic Interview. We calculated the prevalence of PTSD associated with depression, anxiety, heavy drinking, SD, IBS, and chronic pain. Only the analyses on heavy drinking, SD, and IBS used all 607 participants.

RESULTS

Among the 509 adults in primary care, 23% (95% CI, 19-26%) had PTSD, of whom 11% had it noted in the medical record. The prevalence of PTSD, adjusted for age, gender, race, and marital and socioeconomic statuses, was higher in participants with, compared to those without, the following conditions: chronic pain (23 vs 12%, p = .003), major depression (35 vs 11%, p < .0001), anxiety disorders (42 vs 14%, p < .0001), and IBS (34 vs 18%, p = .01) and lower in immigrants (13 vs 21%, p = .05).

CONCLUSIONS

The prevalence of PTSD in the urban primary care setting, and particularly among certain high-risk conditions, compels a critical examination of optimal approaches for screening, intervention, and referral to PTSD treatment.

Prevalence of depression-PTSD comorbidity: implications for clinical practice guidelines and primary care-based interventions

BACKGROUND

Compared to those with depression alone, depressed patients with posttraumatic stress disorder (PTSD) experience more severe psychiatric symptomatology and factors that complicate treatment.

OBJECTIVE

To estimate PTSD prevalence among depressed military veteran primary care patients and compare demographic/illness characteristics of PTSD screen-positive depressed patients (MDD-PTSD+) to those with depression alone (MDD).

DESIGN

Cross-sectional comparison of MDD patients versus MDD-PTSD+ patients.

PARTICIPANTS

Six hundred seventy-seven randomly sampled depressed patients with at least 1 primary care visit in the previous 12 months. Participants composed the baseline sample of a group randomized trial of collaborative care for depression in 10 VA primary care practices in 5 states.

MEASUREMENTS

The Patient Health Questionnaire-9 assessed MDD. Probable PTSD was defined as a Primary Care PTSD Screen > or = 3. Regression-based techniques compared MDD and MDD-PTSD+ patients on demographic/illness characteristics.

RESULTS

Thirty-six percent of depressed patients screened positive for PTSD. Adjusting for sociodemographic differences and physical illness comorbidity, MDD-PTSD+ patients reported more severe depression (P < .001), lower social support (P < .001), more frequent outpatient health care visits (P < .001), and were more likely to report suicidal ideation (P < .001) than MDD patients. No differences were observed in alcohol consumption, self-reported general health, and physical illness comorbidity.

CONCLUSIONS

PTSD is more common among depressed primary care patients than previously thought. Comorbid PTSD among depressed patients is associated with increased illness burden, poorer prognosis, and delayed response to depression treatment. Providers should consider recommending psychotherapeutic interventions for depressed patients with PTSD.

Impact of parental history of substance use disorders on the clinical course of anxiety disorders

Background

Among the psychological difficulties seen in children of parents with substance use problems, the anxiety disorders are among the most chronic conditions. Although children of alcoholic parents often struggle with the effects of parental substance use problems long into adulthood, empirical investigations of the influence of parental substance use disorders on the course of anxiety disorders in adult offspring are rare. The purpose of this study was to examine prospectively the relationship between parental substance use disorders and the course of anxiety disorders in adulthood over the course of 12 years.

Methods

Data on 618 subjects were derived from the Harvard/Brown Anxiety Research Project (HARP), a longitudinal naturalistic investigation of the clinical course of multiple anxiety disorders. Kaplan-Meier survival estimates were used to calculate probabilities of time to anxiety disorder remission and relapse. Proportional hazards regressions were conducted to determine whether the likelihood of remission and relapse for specific anxiety disorders was lower for those who had a history of parental substance use disorders than for individuals without this parental history.

Results

Adults with a history of parental substance use disorders were significantly more likely to be divorced and to have a high school level of education. History of parental substance use disorder was a significant predictor of relapse of social phobia and panic disorders.

Conclusion

These findings provide compelling evidence that adult children of parents with substance use disorders are more likely to have relapses of social phobia and panic disorders. Clinicians who treat adults with anxiety disorders should assess parental substance use disorders and dependence histories. Such information may facilitate treatment planning with regards to their patients' level of vulnerability to perceive scrutiny by others in social situations, and ability to maintain a long-term panic-free state.

Symptoms of post-traumatic stress: intrusion and avoidance 6 and 12 months after TBI

PRIMARY OBJECTIVES

(1) To examine survivors with traumatic brain injury (TBI) for symptoms of avoidance and intrusion, two dimensions of post-traumatic stress (PTS) at 6 and 12 months post-injury. (2) To identify risk factors associated with these symptoms.

RESEARCH DESIGN

Prospective follow-up study.

METHODS AND PROCEDURES

Georgia and North Carolina Model Brain Injury Systems participants (n = 198) with mild (19%), moderate (21%) and severe (60%) TBI were interviewed by telephone at 6 and 12 months post-injury. The Impact of Event Scale (IES) was used to identify intrusion and avoidance symptoms.

RESULTS

Symptoms consistent with severe PTS increased from 11% at 6 months to 16% 12 months post-injury (p < 0.003). African-Americans (p < 0.01) and women (p < 0.05) reported greater symptomatology at 12 months compared to their counterparts. TBI severity and memory of the event were not associated with PTS-like symptoms. Symptoms increased over time when examined by race, injury intent, gender and age (p < 0.05).

CONCLUSIONS

Regardless of severity, survivors with TBI are at risk for developing symptoms consistent with PTS. Amnesia for the injury event was not protective against developing these symptoms. African-Americans appear to be at greatest risk.
