Virtual Reality and Transcranial Direct Current Stimulation for Posttraumatic Stress Disorder: A Randomized Clinical Trial. JAMA Psychiatry 2024; 81:437-446. [PMID: 38446471 PMCID: PMC10918574 DOI: 10.1001/jamapsychiatry.2023.5661] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Accepted: 12/19/2023] [Indexed: 03/07/2024]
Abstract
Importance Posttraumatic stress disorder (PTSD) is a common psychiatric disorder that is particularly difficult to treat in military veterans. Noninvasive brain stimulation has significant potential as a novel treatment to reduce PTSD symptoms. Objective To test whether active transcranial direct current stimulation (tDCS) plus virtual reality (VR) is superior to sham tDCS plus VR for warzone-related PTSD. Design, Setting, and Participants This double-blind randomized clinical trial was conducted among US military veterans enrolled from April 2018 to May 2023 at a secondary care Department of Veterans Affairs hospital and included 1- and 3-month follow-up visits. Participants included US military veterans with chronic PTSD and warzone-related exposure, recruited via referral and advertisement. Patients in psychiatric treatment had to be on a stable regimen for at least 6 weeks to be eligible for enrollment. Data were analyzed from May to September 2023. Intervention Participants were randomly assigned to receive 2-mA anodal tDCS or sham tDCS targeted to the ventromedial prefrontal cortex, during six 25-minute sessions of standardized warzone VR exposure, delivered over 2 to 3 weeks. Main Outcomes and Measures The co-primary outcomes were self-reported PTSD symptoms, measured via the PTSD checklist for DSM-5 (PCL-5), alongside quality of life. Other outcomes included psychophysiological arousal, clinician-assessed PTSD, depression, and social/occupational function. Results A total of 54 participants (mean [SD] age, 45.7 [10.5] years; 51 [94%] males) were assessed, including 26 in the active tDCS group and 28 in the sham tDCS group. Participants in the active tDCS group reported a superior reduction in self-reported PTSD symptom severity at 1 month (t = -2.27, P = .02; Cohen d = -0.82). There were no significant differences in quality of life between active and sham tDCS groups. Active tDCS significantly accelerated psychophysiological habituation to VR events between sessions compared with sham tDCS (F5,7689.8 = 4.65; P < .001). Adverse effects were consistent with the known safety profile of the corresponding interventions. Conclusions and Relevance These findings suggest that combined tDCS plus VR may be a promising strategy for PTSD reduction and underscore the innovative potential of these combined technologies. Trial Registration ClinicalTrials.gov Identifier: NCT03372460.

Study protocol and rationale for a pilot randomized clinical trial comparing processing of positive memories technique with supportive counseling for PTSD. Contemp Clin Trials 2024; 138:107455. [PMID: 38253251 DOI: 10.1016/j.cct.2024.107455] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 11/29/2023] [Accepted: 01/19/2024] [Indexed: 01/24/2024]
Abstract
BACKGROUND Research indicates that positive memories have a role in posttraumatic stress disorder's (PTSD) symptomatology and treatment. Following treatment development guidelines, a novel PTSD intervention - Processing of Positive Memories Technique (PPMT) - was developed and subsequently examined for its effects and feasibility in pilot studies. Extending this research, the proposed pilot randomized clinical trial with PPMT and Supportive Counseling (SC) arms will examine PPMT's effects on PTSD severity and biomarkers of stress systems' dysregulation (awakening salivary alpha amylase [sAA] and cortisol concentrations); examine mechanistic targets (affect) underlying PPMT's effects; and refine PPMT. We hypothesize that the PPMT arm will report greater decreases in PTSD severity and greater decreases in awakening sAA/cortisol ratio compared to the SC arm; and that improved affect (more positive affect and less negative affect) will mediate associations between intervention arm and changes in PTSD severity. METHODS We will recruit 70 individuals aged 18-65 years with PTSD. They will be randomized to 5 weekly therapy sessions of PPMT or SC, and will be assessed at baseline, weekly during treatment, 1-week post-treatment, and 3-months post-treatment. Primary outcomes are past-week PTSD severity, past-week positive and negative affect levels, and feedback data on PPMT's feasibility, format, and content. The secondary outcome is the awakening sAA/cortisol ratio. Statistical analyses include mixed-effect models and within-subjects cross-lag longitudinal mediation analyses. CONCLUSION Study results will advance knowledge of trauma interventions by examining effects and feasibility of a novel PTSD intervention, and by elucidating potential mechanisms underlying PPMT's effects.

Abstract
OBJECTIVE Research has shown a consistent, negative correlation between social support and PTSD severity among a variety of populations, including military servicemembers and veterans. However, longitudinal data has been mixed on the direction of this effect. One possible explanation for these contradictory findings is that the direction of the effect varies depending on the function of social support. The current study examined naturalistic longitudinal associations between functions of social support and PTSD symptoms among returning veterans. METHOD 238 military veterans who had deployed to Afghanistan or Iraq were recruited. Veterans were assessed at baseline, 6, 12, and 24-months postdeployment. Assessments included a self-report measure of perceived social support by support function and the Clinician Administered PTSD Scale to measure PTSD symptoms. Multilevel modeling was used to test longitudinal associations between PTSD symptoms and social support. Secondary analyses tested associations by PTSD symptom cluster. RESULTS Between-person PTSD symptom severity was associated with lower average social support of all functions of support and predicted decreases in tangible support over time. Between-person belonging support predicted decreases in PTSD symptom severity over time. No within-person effects were significant. Supplemental analyses suggested the DSM-IV-TR avoidance/numbing cluster of PTSD was most consistently associated with lower social support. CONCLUSIONS The direction of associations between PTSD symptoms and support varied by function of support, suggesting nuanced associations between PTSD and perceived social support. Clinicians should assess and target social functioning during PTSD treatment. Further research is needed to replicate findings in other populations and for other trauma types.

A randomized clinical trial comparing Interpersonal Psychotherapy with Prolonged Exposure for the treatment of PTSD in veterans. J Anxiety Disord 2023; 99:102770. [PMID: 37738685 DOI: 10.1016/j.janxdis.2023.102770] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 07/25/2023] [Accepted: 09/03/2023] [Indexed: 09/24/2023]
Abstract
Trauma-focused therapies are recommended as first-line treatments for posttraumatic stress disorder (PTSD), but many veterans do not complete or sufficiently respond to these treatments. Interpersonal Therapy (IPT) is a non-trauma focused approach that directly addresses the interpersonal and social impairments associated with PTSD. This two-site randomized controlled equivalence trial compared IPT with Prolonged Exposure (PE) in improving PTSD symptoms and interpersonal functioning in 109 veterans with PTSD. Secondary outcomes included functioning and quality of life. We hypothesized that IPT would be statistically equivalent to PE in reducing PTSD symptoms, and superior to PE in improving interpersonal functioning and secondary outcomes of work and social adjustment and quality of life. PTSD symptom severity decreased significantly in both treatments from pre- to post-treatment. Although IPT improved as much as PE and treatments did not differ significantly, the 95 % confidence interval for the difference between the groups did not fall completely within the margin of equivalence. IPT was not superior to PE in improvement in interpersonal functioning or on secondary outcomes. Findings from multi-level linear mixed models using longitudinal data (posttreatment, three and six month follow up) for the primary outcomes of PTSD and interpersonal functioning were consistent with the post-treatment analyses. Although statistically inconclusive in terms of equivalence, the comparable reduction in PTSD symptoms slightly favoring IPT suggests that IPT is an acceptable alternative to gold-standard trauma-focused treatments for veterans with PTSD.

Borderline personality disorder symptom networks across adolescent and adult clinical samples: examining symptom centrality and replicability. Psychol Med 2023; 53:2946-2953. [PMID: 35094733 PMCID: PMC9339041 DOI: 10.1017/s0033291721004931] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 10/22/2021] [Accepted: 11/09/2021] [Indexed: 11/05/2022]
Abstract
BACKGROUND Numerous theories posit different core features to borderline personality disorder (BPD). Recent advances in network analysis provide a method of examining the relative centrality of BPD symptoms, as well as examine the replicability of findings across samples. Additionally, despite the increase in research supporting the validity of BPD in adolescents, clinicians are reluctant to diagnose BPD in adolescents. Establishing the replicability of the syndrome across adolescents and adults informs clinical practice and research. This study examined the stability of BPD symptom networks and centrality of symptoms across samples varying in age and clinical characteristics. METHODS Cross-sectional analyses of BPD symptoms from semi-structured diagnostic interviews from the Collaborative Longitudinal Study of Personality Disorders (CLPS), the Methods to Improve Diagnostic Assessment and Service (MIDAS) study, and an adolescent clinical sample. Network attributes, including edge (partial association) strength and node (symptom) expected influence, were compared. RESULTS The three networks were largely similar and strongly correlated. Affective instability and identity disturbance emerged as relatively central symptoms across the three samples, and relationship difficulties across adult networks. Differences in network attributes were more evident between networks varying both in age and in BPD symptom severity level. CONCLUSIONS Findings highlight the relative importance of affective, identity, and relationship symptoms, consistent with several leading theories of BPD. The network structure of BPD symptoms appears generally replicable across multiple large samples including adolescents and adults, providing further support for the validity of the diagnosis across these developmental phases.

Comparative effectiveness of trauma-focused and non-trauma-focused psychotherapy for PTSD among veterans with comorbid substance use disorders: Protocol & rationale for a randomized clinical trial. Contemp Clin Trials 2022; 120:106876. [PMID: 35987487 DOI: 10.1016/j.cct.2022.106876] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2022] [Revised: 07/28/2022] [Accepted: 08/04/2022] [Indexed: 11/03/2022]
Abstract
BACKGROUND Co-occurrence of posttraumatic stress disorder (PTSD) and substance use disorders (SUDs) is common and concurrent treatment is recommended. Relatively little is known about which evidence-based psychotherapies for PTSD are most effective for patients with varying substance use profiles. We aim to examine the comparative effectiveness of trauma-focused therapy (TFT) and non-trauma-focused therapy (NTFT) among Veterans with PTSD and SUD. TFT has been found to be effective among those with PTSD/SUD, though effects are smaller and rates of treatment non-completion are higher than in those without SUD. NTFTs suggested for the treatment of PTSD, such as Present Centered Therapy, (PCT) have not been examined among those with co-occurring SUD, despite lower rates of treatment dropout. We will also examine the comparative effectiveness of TFT and NTFT for patients with varying SUD severity, type of substances used, and patient treatment preference. METHOD 420 Veterans with PTSD and SUD will be randomized in a prospective, pragmatic comparative effectiveness trial at 14 Veterans Health Administration facilities. Participants will receive either TFT (Prolonged Exposure or Cognitive Processing Therapy) or NTFT (PCT) after enrolling in concurrent SUD treatment-as-usual. Assessments will occur at baseline, posttreatment, 3- and 6 -months posttreatment. Main outcomes are PTSD symptom severity and PTSD treatment dropout. Clinician, patient, and leadership stakeholder panels advise study activities, and a process evaluation will identify strategies to enhance the implementation of evidence-based PTSD treatments in SUD care settings. CONCLUSIONS Results will provide critical information to guide clinicians when recommending PTSD treatments to patients with comorbid SUD. CLINICALTRIALS gov Identifier: NCT04581434.

Abstract
BACKGROUND Problems with anger and aggression affect many veterans who have deployed to a warzone, resulting in serious impairment in multiple aspects of functioning. Controlled studies are needed to improve treatment options for these veterans. This randomized controlled trial compared an individually delivered cognitive behavioral therapy adapted from Novaco's Anger Control Therapy to a manualized supportive therapy to control for common therapeutic factors. METHODS Ninety-two post-911 veterans deployed during Operation Enduring Freedom (OEF), Operation Iraqi Freedom (OIF), or Operation New Dawn (OND) with moderate to severe anger problems were randomized to receive the cognitive behavioral intervention (CBI) or the supportive intervention (SI). Anger, aggression, multiple areas of functioning and quality of life were assessed at multiple time points inclu\ding 3- and 6-month follow-up. RESULTS Hierarchical linear modeling (HLM) analyses showed significant treatment effects favoring CBI for anger severity, social and interpersonal functioning, and quality of life. The presence of a PTSD diagnosis did not affect outcomes. CONCLUSIONS CBI is an effective treatment for OEF/OIF/OND veterans with anger problems following deployment, regardless of PTSD diagnosis.

A clinical trial comparing trauma-informed guilt reduction therapy (TrIGR), a brief intervention for trauma-related guilt, to supportive care therapy. Depress Anxiety 2022; 39:262-273. [PMID: 35075738 DOI: 10.1002/da.23244] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Revised: 01/06/2022] [Accepted: 01/14/2022] [Indexed: 12/15/2022] Open
Abstract
INTRODUCTION Trauma-related guilt is common, associated with posttraumatic mental health problems, and can persist after posttraumatic stress disorder (PTSD) treatment. We compared the efficacy of two six-session psychotherapies, Trauma-Informed Guilt Reduction (TrIGR) and Supportive Care Therapy (SCT), for reducing trauma-related guilt. TrIGR helps patients accurately appraise their role in the trauma and re-engage in values. In SCT, patients guide session content. METHODS A total of 184 veterans seeking VA mental health services were enrolled across two sites; 145 veterans (mean age: 39.2 [8.1]; 92.4% male; 84.8% with PTSD) who endorsed guilt related to a traumatic event that occurred during a post 9/11 Iraq or Afghanistan deployment were randomized and assessed at baseline, posttreatment, 3- and 6-month follow-up. RESULTS Linear mixed models using intent-to-treat analyses showed guilt decreased in both conditions with a greater decrease for TrIGR (treatment × time, -0.22; F 1, 455.2 = 18.49, p = .001; d = 0.92) than supportive therapy. PTSD and depressive symptoms showed the same pattern. TrIGR had significantly higher likelihood of PTSD treatment response (67% vs. 40%), loss of PTSD diagnosis (50% vs. 14%), and meaningful change in depression (54% vs. 27%) than supportive therapy. Psychological distress and trait shame improved in both conditions. Quality of life did not change. CONCLUSIONS Targeting guilt appears to be an effective means for reducing posttraumatic symptoms and distress.

Abstract
IMPORTANCE Borderline personality disorder (BPD) has been identified as a strong risk factor for suicidal behavior, including suicide attempts. Delineating specific features that increase risk could inform interventions. OBJECTIVE To examine factors associated with prospectively observed suicide attempts among participants in the Collaborative Longitudinal Study of Personality Disorders (CLPS), over 10 years of follow-up, with a focus on BPD and BPD criteria. DESIGN, SETTING, AND PARTICIPANTS The CLPS is a multisite, naturalistic, prospective study of adult participants with 4 personality disorders (PDs) and a comparison group of adults with major depressive disorder and minimal PD features. Participants were all treatment-seeking and recruited from inpatient, partial, and outpatient treatment settings across New York, New York, Boston, Massachusetts, New Haven, Connecticut, and Providence, Rhode Island. A total of 733 participants were recruited at baseline, with 701 completing at least 1 follow-up assessment. The cohorts were recruited from September 1996 through April 1998 and September 2001 through August 2002. Data for this study using this follow-up sample (N = 701) were analyzed between March 2019 and August 2020. MAIN OUTCOMES AND MEASURES Participants were assessed annually using semistructured diagnostic interviews and a variety of self-report measures for up to 10 years. Multiple logistic regression analyses were used to examine baseline demographic and clinical risk factors, including BPD and individual BPD criteria, of suicide attempt assessed over 10 years of prospective follow-up. RESULTS Of the 701 participants, 447 (64%) identified as female, 488 (70%) as White, 527 (75%) as single, 433 (62%) were unemployed, and 512 (73%) reported at least some college education. Of all disorders, BPD emerged as the most robust factor associated with prospectively observed suicide attempt(s) (odds ratio [OR], 4.18; 95% CI, 2.68-6.52), even after controlling for significant demographic (sex, employment, and education) and clinical (childhood sexual abuse, alcohol use disorder, substance use disorder, and posttraumatic stress disorder) factors. Among BPD criteria, identity disturbance (OR, 2.21; 95% CI, 1.37-3.56), chronic feelings of emptiness (OR, 1.63; 95% CI, 1.03-2.57), and frantic efforts to avoid abandonment (OR, 1.93; 95% CI, 1.17-3.16) emerged as significant independent factors associated with suicide attempt(s) over follow-up, when covarying for other significant factors and BPD criteria. CONCLUSIONS AND RELEVANCE In the multisite, longitudinal study of adults with personality disorders, identity disturbance, chronic feelings of emptiness, and frantic efforts to avoid abandonment were significantly associated with suicide attempts. Identity disturbance, chronic feelings of emptiness, and frantic efforts to avoid abandonment may be clinically overlooked features of BPD in context of suicide risk assessment. In light of the high rates of BPD diagnostic remission, our findings suggest that these criteria should be independently assessed and targeted for further study as suicide risk factors.

Abstract
Guilt, shame, and moral injury (MI) are common reactions following exposure to traumatic events and are associated with greater severity of several mental health problems, including posttraumatic stress disorder (PTSD), depression, increased risk of suicidal ideation and poorer psychosocial functioning. Trauma-Informed Guilt Reduction (TrIGR) is a transdiagnostic psychotherapy to address guilt, shame, and MI stemming from traumatic events. The primary goals of TrIGR are to help patients accurately appraise their trauma and to re-engage with their values in order to lead a more meaningful life. This paper presents the rationale, design, and methodology of a two-site randomized controlled trial (RCT) examining the efficacy of TrIGR compared to Supportive Care Therapy (SCT) in a sample of U.S. veterans (N = 145) who endorse guilt related to a traumatic event that occurred during military deployment. This study is the first RCT powered to investigate TrIGR's efficacy on reducing posttraumatic guilt, as measured by the Trauma Related Guilt Inventory (TRGI), in comparison to an active control condition. In addition, the study will examine a range of secondary and exploratory outcomes including shame, quality of life, suicidal ideation, substance use, and PTSD and depression symptoms. Findings from this efficacy study will be essential in informing future efficacy and effectiveness trials.

Abstract
BACKGROUND Cognitive Behavioral Social Rhythm Group Therapy (CBSRT) is a chronobiologically-informed group therapy designed to stabilize social rhythms in veterans with comorbid combat-related PTSD and major depressive disorder (MDD). This randomized controlled pilot trial is the first to examine feasibility and preliminary efficacy of group CBSRT as compared to group Present Centered Therapy (PCT), a well-characterized active attention, psychotherapy condition. METHODS A total of 43 male veterans with combat-related PTSD, MDD, and disruptions in sleep or daily routine were randomly assigned to CBSRT or PCT. Therapy was provided weekly in a group modality for 12 weeks. Follow-up feasibility and gold-standard PTSD, MDD, and subjective/objective sleep assessments were conducted at post-treatment, 3 months, and 6 months post-treatment. RESULTS Feasibility results demonstrated that veterans assigned to CBSRT had higher rates of attendance than veterans assigned to PCT. Both CBSRT and PCT were associated with improvements in PTSD and MDD symptoms, sleep efficiency, and number of awakenings; there were no differences between group therapies on these indices. Veterans in the CBSRT group had a greater reduction in the number of nightmares than veterans in the PCT group. LIMITATIONS Preliminary results must be qualified by the small sample size. CONCLUSIONS Group CBSRT may be more feasible for veterans than PCT. Both CBSRT and PCT were associated with improvements in psychiatric symptoms with few differences between conditions. CBSRT is a promising new group therapy that may help address the high-rate of PTSD therapy attrition in combat veterans. CLINICAL TRIAL REGISTRATION NCT00984698.

Abstract
Co-occurring posttraumatic stress disorder (PTSD) and substance use disorders (SUD) following combat exposure affects a significant proportion of military veterans. Guilt and shame are common to PTSD-SUD, suggesting a possible role as a mechanism underlying both disorders. Cultivating self-compassion (SC) among veterans is a logical approach to treating guilt and shame. The purpose of this article is threefold: (a) present scientific theories of SC in the veteran population with emphasis on PTSD, substance use, and guilt and shame; (b) present a case study that highlights how self-compassion-focused treatment (SCFT) can be utilized in a group format with veterans with PTSD-SUD and posttraumatic guilt; and (c) discuss implications of our findings for refining SCFT within a group intervention setting among this population and for future research.

Abstract
Despite substantial evidence linking posttraumatic stress disorder (PTSD) and positive memory processes, existing trauma research and clinical work focuses primarily on traumatic memories. In light of this limitation, Contractor and colleagues proposed a conceptual model linking PTSD to positive memories; this provided the backdrop to develop a manualized positive memory therapy protocol for trauma-exposed individuals (Processing of Positive Memories Technique; PPMT). In the current study, we first present justification for developing PPMT by outlining the role of positive memories in trauma theories, as well as empirical evidence and intervention research linking trauma/PTSD to positive memory processes. Next, we provide information on the preliminary PPMT protocol by outlining (1) theoretical foundations; (2) intervention strategies PPMT draws from; (3) objectives; and (4) a session-by-session description of goals, content, and homework assignments. Finally, we end by highlighting some (1) unique features and advantages of PPMT such as integrating well-supported experimental and cognitive psychology research into intervention research, bridging the gap between basic science and applied research, and being tailored to PTSD's unique symptomatology; and (2) directions for future research. The aim of this paper was to provide a primer on PPMT to facilitate its empirical examination and applicability in PTSD research and clinical work.

Abstract
OBJECTIVE There is an urgent need to identify ways to reduce rates of suicide among Veterans with a substance use disorder. Since co-occurring disorders can make diagnosis and treatment complex, it is useful for the mental health field to examine common factors that may underlie both problems. One common factor that underlies both substance use and suicidal behavior is shame. This brief report presents data collected in an experimental study examining shame as an acute risk factor for suicide and substance use in Veterans. METHOD Thirty-eight Veterans admitted to an inpatient Veterans Affairs Medical Center unit with suicidal ideation completed measures on depression, hopelessness, addiction, and suicidality. Participants were randomized to either a shame mood induction group or a control group, and completed pre- and postexperiment measures on urges for suicide, urges for substance use, and level of shame. RESULTS Results indicate that an acute increase in shame resulted in an increase in an urge for suicide, but was not associated with changes in urges for substance use. CONCLUSIONS Acute feelings of shame may be a risk factor for increases in suicidal ideation. Limitations and suggestions for future directions are discussed.

Sexual trauma is prevalent among women veterans and associated with health risks including hazardous drinking, intimate partner violence (IPV), and post-traumatic stress disorder (PTSD). Safe and Healthy Experiences (SHE) is a computerized intervention to reduce these health risks. SHE was pilot tested in an open trial (N = 20) with women veterans with a history of sexual trauma and associated health risks. Women reported high satisfaction with the intervention and computerized delivery and they evidenced reductions in hazardous drinking, IPV, and PTSD at 4 months. SHE appears to be satisfactory, feasible, and potentially beneficial to women veterans.

Abstract
BACKGROUND Present-centered therapy (PCT) is a non-trauma, manualized psychotherapy for adults with post-traumatic stress disorder (PTSD). PCT was originally designed as a treatment comparator in trials evaluating the effectiveness of trauma-focused cognitive-behavioral therapy (TF-CBT). Recent trials have indicated that PCT may be an effective treatment option for PTSD and that patients may drop out of PCT at lower rates relative to TF-CBT. OBJECTIVES To assess the effects of PCT for adults with PTSD. Specifically, we sought to determine whether (1) PCT is more effective in alleviating symptoms relative to control conditions, (2) PCT results in similar alleviation of symptoms compared to TF-CBT, based on an a priori minimally important differences on a semi-structured interview of PTSD symptoms, and (3) PCT is associated with lower treatment dropout as compared to TF-CBT. SEARCH METHODS We searched the Cochrane Common Mental Disorders Controlled Trials Register, the Cochrane Library, Ovid MEDLINE, Embase, PsycINFO, PubMed, and PTSDpubs (previously called the Published International Literature on Traumatic Stress (PILOTS) database) (all years to 15 February 2019 search). We also searched the World Health Organization (WHO) trials portal (ICTRP) and ClinicalTrials.gov to identify unpublished and ongoing trials. Reference lists of included studies and relevant systematic reviews were checked. Grey literature searches were also conducted to identify dissertations and theses, clinical guidelines, and regulatory agency reports. SELECTION CRITERIA We selected all randomized clinical trials (RCTs) that recruited adults diagnosed with PTSD to evaluate PCT compared to TF-CBT or a control condition. Both individual and group PCT modalities were included. The primary outcomes of interest included reduced PTSD severity as determined by a clinician-administered measure and treatment dropout rates. DATA COLLECTION AND ANALYSIS We complied with the Cochrane recommended standards for data screening and collection. Two review authors independently screened articles for inclusion and extracted relevant data from eligible studies, including the assessment of trial quality. Random-effects meta-analyses, subgroup analyses, and sensitivity analyses were conducted using mean differences (MD) and standardized mean differences (SMD) for continuous data or risk ratios (RR) and risk differences (RD) for dichotomous data. To conclude that PCT resulted in similar reductions in PTSD symptoms relative to TF-CBT, we required a MD of less than 10 points (to include the 95% confidence interval) on the Clinician-Administered PTSD Scale (CAPS). Five members of the review team convened to rate the quality of evidence across the primary outcomes. Any disagreements were resolved through discussion. Review authors who were investigators on any of the included trials were not involved in the qualitative or quantitative syntheses. MAIN RESULTS We included 12 studies (n = 1837), of which, three compared PCT to a wait-list/minimal attention (WL/MA) group and 11 compared PCT to TF-CBT. PCT was more effective than WL/MA in reducing PTSD symptom severity (SMD -0.84, 95% CI -1.10 to -0.59; participants = 290; studies = 3; I² = 0%). We assessed the quality of this evidence as moderate. The results of the non-inferiority analysis comparing PCT to TF-CBT did not support PCT non-inferiority, with the 95% confidence interval surpassing the clinically meaningful cut-off (MD 6.83, 95% CI 1.90 to 11.76; 6 studies, n = 607; I² = 42%). We assessed this quality of evidence as low. CAPS differences between PCT and TF-CBT attenuated at 6-month (MD 1.59, 95% CI -0.46 to 3.63; participants = 906; studies = 6; I² = 0%) and 12-month (MD 1.22, 95% CI -2.17 to 4.61; participants = 485; studies = 3; I² = 0%) follow-up periods. To confirm the direction of the treatment effect using all eligible trials, we also evaluated PTSD SMD differences. These results were consistent with the primary MD outcomes, with meaningful effect size differences between PCT and TF-CBT at post-treatment (SMD 0.32, 95% CI 0.08 to 0.56; participants = 1129; studies = 9), but smaller effect size differences at six months (SMD 0.17, 95% CI 0.05 to 0.29; participants = 1339; studies = 9) and 12 months (SMD 0.17, 95% CI 0.03 to 0.31; participants = 728; studies = 5). PCT had approximately 14% lower treatment dropout rates compared to TF-CBT (RD -0.14, 95% CI -0.18 to -0.10; participants = 1542; studies = 10). We assessed the quality of this evidence as moderate. There was no evidence of meaningful differences on self-reported PTSD (MD 4.50, 95% CI 3.09 to 5.90; participants = 983; studies = 7) or depression symptoms (MD 1.78, 95% CI -0.23 to 3.78; participants = 705; studies = 5) post-treatment. AUTHORS' CONCLUSIONS Moderate-quality evidence indicates that PCT is more effective in reducing PTSD severity compared to control conditions. Low quality of evidence did not support PCT as a non-inferior treatment compared to TF-CBT on clinician-rated post-treatment PTSD severity. The treatment effect differences between PCT and TF-CBT may attenuate over time. PCT participants drop out of treatment at lower rates relative to TF-CBT participants. Of note, all of the included studies were primarily designed to test the effectiveness of TF-CBT which may bias results away from PCT non-inferiority.The current systematic review provides the most rigorous evaluation to date to determine whether PCT is comparably as effective as TF-CBT. Findings are generally consistent with current clinical practice guidelines that suggest that PCT may be offered as a treatment for PTSD when TF-CBT is not available.

Abstract
OBJECTIVE Posttraumatic stress disorder (PTSD) is a highly prevalent psychiatric disorder associated with disruption in social and occupational function. Transcranial magnetic stimulation (TMS) represents a novel approach to PTSD, and intermittent theta-burst stimulation (iTBS) is a new, more rapid administration protocol with data supporting efficacy in depression. The authors conducted a sham-controlled study of iTBS for PTSD. METHODS Fifty veterans with PTSD received 10 days of sham-controlled iTBS (1,800 pulses/day), followed by 10 unblinded sessions. Primary outcome measures included acceptability (retention rates), changes in PTSD symptoms (clinician- and self-rated), quality of life, social and occupational function, and depression, obtained at the end of 2 weeks; analysis of variance was used to compare active with sham stimulation. Secondary outcomes were evaluated 1 month after treatment, using mixed-model analyses. Resting-state functional MRI was acquired at pretreatment baseline on an eligible subset of participants (N=26) to identify response predictors. RESULTS Retention was high, side effects were consistent with standard TMS, and blinding was successful. At 2 weeks, active iTBS was significantly associated with improved social and occupational function (Cohen's d=0.39); depression was improved with iTBS compared with the sham treatment (d=-0.45), but the difference fell short of significance, and moderate nonsignificant effect sizes were observed on self-reported PTSD symptoms (d=-0.34). One-month outcomes, which incorporated data from the unblinded phase of the study, indicated superiority of active iTBS on clinician- and self-rated PTSD symptoms (d=-0.74 and -0.63, respectively), depression (d=-0.47), and social and occupational function (d=0.93) (all significant). Neuroimaging indicated that clinical improvement was significantly predicted by stronger (greater positive) connectivity within the default mode network and by anticorrelated (greater negative) cross-network connectivity. CONCLUSIONS iTBS appears to be a promising new treatment for PTSD. Most clinical improvements from stimulation occurred early, which suggests a need for further investigation of optimal iTBS time course and duration. Consistent with previous neuroimaging studies of TMS, default mode network connectivity played an important role in response prediction.

Treatment of trauma related anger in operation enduring freedom, operation Iraqi freedom, and operation New Dawn veterans: Rationale and study protocol. Contemp Clin Trials Commun 2018; 12:26-31. [PMID: 30225391 PMCID: PMC6138955 DOI: 10.1016/j.conctc.2018.08.011] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2018] [Revised: 08/10/2018] [Accepted: 08/23/2018] [Indexed: 01/18/2023] Open
Abstract
Background Problems with anger and aggression are highly prevalent in Veterans of multiple war eras, including the most recent conflicts in Afghanistan (Operation Enduring Freedom; OEF) and Iraq (Operation Iraqi Freedom; OIF). The consequences of these problems, such as increased rates of divorce, domestic violence, occupational instability, arrests and incarceration, are often devastating. Despite the seriousness of these problems, relatively little is known about effective treatments for anger in Veterans. Method and design This paper describes the rationale and study protocol of a randomized controlled trial comparing an adapted cognitive behavioral intervention (CBI) with an active control condition (supportive intervention, SI) for the treatment of anger problems in OEF/OIF Veterans. The sample includes 92 OEF/OIF Veterans, randomized to CBI or SI. Both treatments include 12 weekly, 75-min individual sessions. Participants are assessed at baseline, after sessions 4 and 8, at post-treatment, and at 3 and 6 months post-treatment. Primary outcomes are reduction in anger and aggression; secondary outcomes are improved functioning and quality of life. We hypothesize that CBI will be associated with significantly more improvement than SI on primary and secondary measures. Discussion Findings from this study will help to address the gap in evidence for effective treatments for anger in Veterans. The use of an active control condition will provide a stringent test of the effects of CBI beyond that of common factors of psychotherapy such as therapeutic relationship, mobilization of hope, and support. Findings have the potential to improve treatment outcomes for Veterans struggling with post-deployment anger problems.

Abstract
Encoding and retrieval difficulties, and avoidance of both traumatic and positive memories, are associated with posttraumatic stress disorder (PTSD) symptoms. However, most PTSD research and clinical work has solely examined the role of traumatic memories in the maintenance/resolution of PTSD symptoms. This review provides a comprehensive discussion of the literature on positive memories and PTSD. First, we review theories and evidence on the relations between trauma, PTSD, and memory processes (particularly positive memories). Next, we propose a conceptual model that integrates evidence from experimental and positive/memory-based intervention research and highlights hypothesized mechanisms underlying the potential effectiveness of targeting positive memories in PTSD interventions. Specifically, we discuss how targeting positive memories could (1) increase positive affect and reduce negative affect, (2) correct negative cognitions, (3) increase specificity of retrieving autobiographical memories, and (4) be effectively integrated/sequenced with and enhance the effects of trauma-focused interventions. Lastly, we suggest clinical research avenues for investigating the relations between positive memories and PTSD, to possibly alter the current PTSD intervention paradigm focused only on traumatic memories. Overall, our proposed model drawing from experimental and intervention research, and outlining potential effects of targeting positive memories to reduce PTSD severity, needs further empirical investigation.

Abstract
Interest in virtual reality (VR) as a clinical tool to augment posttraumatic stress (PTSD) treatment has grown substantially in recent years due to advances in VR technology. Moreover, its potential assisted use in the PTSD diagnostic process has been recognized. In this study we examined physiological responding, skin conductance, to a standardized presentation of non-personalized combat-related VR events (e.g. encountering enemy fire; explosions) as compared to non-combat classroom VR events in 19 Veterans with and 24 Veterans without combat-related PTSD who had been deployed to Iraq and Afghanistan. Veterans watched a total of 12 VR scenarios-six combat-related and six non-combat-related-with each scenario gradually increasing in emotional intensity by adding more VR events in addition to repeating prior VR events. Results show that Veterans with PTSD displayed larger skin conductance reactivity across VR combat events, but not for non-combat VR events, as compared to combat Veterans without PTSD. Nevertheless, Veterans with and without PTSD showed a similar reduction of emotional arousal to repeated presentation of the same VR combat events. Within the PTSD sample, the elevated level of VR combat-related arousal correlated marginally with severity of hyperarousal symptoms. This study confirms that the use of a non-personalized and standardized VR presentation successfully distinguishes Veterans with PTSD from those without on a measure of psychophysiological arousal to combat-related VR stimuli. The assessment of physiological reactivity during the repeated presentation of standardized, trauma-related VR events highlights its use for PTSD assessment as well as treatment.

Abstract
OBJECTIVE Childhood maltreatment is an increasingly established predictor of psychological problems. However, limited research addresses pathways though which childhood maltreatment influences the mental health of military personnel following deployment. The current study investigated the direct, and indirect through emotional numbing, relations between childhood maltreatment and psychological distress of recently deployed veterans. METHOD For a sample of 131 predominantly White, male Operation Iraqi Freedom/Operation Enduring Freedom members of U.S. Army National Guard and Reserve units, a path model was used to test the direct and indirect (through numbing) roles of childhood maltreatment on distress. RESULTS Results showed that childhood maltreatment was not significantly directly associated with psychological distress one-year post-deployment but was indirectly related to distress by way of emotional numbing symptoms. CONCLUSIONS Our findings suggest that childhood maltreatment may serve to influence returning veterans' experiences of psychological distress indirectly through increased emotional numbing following deployment. The importance of attending to emotional numbing symptoms among veterans with experiences of childhood maltreatment after deployment is highlighted. (PsycINFO Database Record

Abstract
Military service members have an increased risk of developing mental health (MH) problems following deployment to Iraq or Afghanistan, yet only a small percentage seek mental health treatment. The aim of the present study was to explore patterns of MH service utilization within the first 12 months following return from combat deployment. Participants were 169 service members who had returned from war-zone deployment in either Iraq or Afghanistan and had assessments covering a 12-month period following their homecoming. The authors first examined the prevalence of mental health diagnoses and engagement with mental health treatment (e.g., visits to the emergency room, inpatient hospitalization, individual therapy, group therapy, family or couple therapy, medication appointments, and self-help). Regression analyses explored whether distress, functioning, diagnoses, or social support predicted treatment use. Findings indicated that 28 of 50 military service members (56%) who met diagnostic criteria for a mental health disorder accessed services in the year following their return from deployment. Individual treatment was the most common modality, and those with major depressive disorder (MDD) reported the most treatment contacts. Social support was not associated with use of mental health services. Baseline functioning and psychiatric distress predicted entry into treatment whereas only psychiatric distress predicted amount of mental health service use in the 12-month postdeployment period. Findings highlight the need for enhanced strategies to link those reporting psychiatric distress with MH treatment services and increase community connectedness regardless of whether they meet full criteria for a mental health diagnosis.

Abstract
Individuals with a personality disorder (PD) tend to experience more negative life events (NLEs) than positive life events (PLEs). In community samples, the Five Factor Model of personality (FFM) predicts both positive and negative life events. The present research examined whether FFM normal personality traits were associated with positive and negative life events among individuals with 1 of 4 PDs: avoidant, borderline, schizotypal, and obsessive-compulsive, and tested whether associations between the FFM of personality and PLEs and NLEs were similar across the 4 PD groups and a control group. Among aggregated PDs, neuroticism was positively associated with NLEs, whereas extraversion, openness to experience, and conscientiousness were positively associated with PLEs. Comparisons of each PD group to a control group of individuals with a major depressive disorder indicated that the FFM traits operated similarly across clinical samples with and without PD. Our findings indicate that normal personality traits can be used to help understand the lives of individuals with PD. (PsycINFO Database Record

Abstract
Posttraumatic Stress Disorder (PTSD) is frequently comorbid with alcohol use disorders (AUD; Calabrese et al., 2011; McFall, Mackay, & Donovan, 1992). Among several explanations for this comorbidity, the most empirically supported is the self-medication theory which postulates that substances are used to medicate PTSD-related distress (Keane & Wolfe, 1990; Khantzian, 1985; Stewart, 1996). The current study examines the effects of trauma-related distress on alcohol use (total drinking days, drinks per drinking day, heavy drinking days) in a sample of 127 trauma-exposed Veterans following deployment to Iraq or Afghanistan. The dysphoria symptoms of PTSD were used as an indicator of distress, and examined as a moderator in the relationship between intrusion symptoms of PTSD and alcohol use. The proposed moderation model was tested using cross-sectional data from the first month following return from deployment, and at 6 months and at 12 months post-deployment. Results showed that dysphoria symptoms significantly moderated relations between intrusions and total drinking days and heavy drinking days at one month post-deployment; however, a significant pattern was not demonstrated at 6 months and 12 months. Further, dysphoria did not moderate the relation between intrusion symptoms and drinks per drinking day at the three time points. Theoretical and clinical implications are subsequently discussed.

Abstract
Typologies of DSM-5 PTSD symptoms and personality traits were evaluated in regard to coping styles and treatment preferences using data from 1266 trauma-exposed military veterans of which the majority were male (n=1097; weighted 89.6%). Latent profile analyses indicated a best-fitting 5-class solution; PTSD asymptomatic and emotionally stable (C1); predominant re-experiencing and avoidance symptoms and less emotionally stable (C2); subsyndromal PTSD (C3); predominant negative alterations in mood/cognitions and combined internalizing-externalizing traits (C4); and high PTSD severity and combined internalizing-externalizing traits (C5). Compared to C5, C1 members were less likely to use self-distraction, denial, and substance use and more likely to use active coping; C2 and C4 members were less likely to use denial and more likely to use behavioral disengagement; C3 members were less likely to use denial and instrumental coping and more likely to use active coping; most classes were less likely to seek mental health treatment. Compared to C1, C2 members were more likely to use self-distraction, substance use, behavioral disengagement and less likely to use active coping; C3 members were more likely to use self-distraction, and substance use, and less likely to use positive reframing, and acceptance; and C4 members were more likely to use denial, substance use, emotional support, and behavioral disengagement, and less likely to use active coping, positive reframing, and acceptance; all classes were more likely to seek mental health treatment. Emotional stability was most distinguishing of the typologies. Other implications are discussed.

Abstract
Few studies have investigated emotional functioning in obsessive-compulsive personality disorder (OCPD). To explore the nature and extent of emotion difficulties in OCPD, the authors examined four domains of self-reported emotional functioning--negative affectivity, anger, emotion regulation, and emotion expressivity--in women with OCPD and compared them to a borderline personality disorder (BPD) group and a healthy control group. Data were collected as part of a larger psychophysiological experimental study on emotion regulation and personality. Compared to healthy controls, participants with OCPD reported significantly higher levels of negative affectivity, trait anger, emotional intensity, and emotion regulation difficulties. Emotion regulation difficulties included lack of emotional clarity, nonacceptance of emotional responses, and limited access to effective emotion regulation strategies. Participants with OCPD scored similarly to participants with BPD on only one variable, namely, problems engaging in goal-directed behavior when upset. Results suggest that OCPD may be characterized by notable difficulties in several emotional domains.

Abstract
OBJECTIVE This report examines the relationship of DSM-IV borderline personality disorder (BPD) to anxiety disorders using data on the reciprocal effects of improvement or worsening of BPD and anxiety disorders over the course of 10 years. METHOD We reliably and prospectively assessed borderline patients (n = 164) with DSM-IV-defined co-occurring generalized anxiety disorder (GAD; n = 42), panic disorder with agoraphobia (n = 39), panic disorder without agoraphobia (n= 36), social phobia (n = 48), obsessive-compulsive disorder (OCD; n = 36), and posttraumatic stress disorder (PTSD; n = 88) annually over a period of 10 years between 1997 and 2009. We used proportional hazards regression analyses to assess the effects of monthly improvement or worsening of BPD and anxiety disorders on each other's remission and relapse the following month. RESULTS BPD improvement significantly predicted remission of GAD (hazard ratio [HR] = 0.65, P <.05) and PTSD (HR = 0.57, P < .05), whereas BPD worsening significantly predicted social phobia relapse (HR = 1.87, P < .05). The course of anxiety disorders did not predict BPD remission or relapse, except that worsening PTSD significantly predicted BPD relapse (HR = 1.90, P < .05). CONCLUSION BPD negatively affects the course of GAD, social phobia, and PTSD. In contrast, the anxiety disorders, aside from PTSD, had little effect on BPD course. For GAD and social phobia, whose course BPD unidirectionally influences, we suggest prioritizing treatment for BPD, whereas BPD should be treated concurrently with panic disorders, OCD, or PTSD. We discuss state/trait issues in the context of our findings.

Abstract
Social neuroscience is a new, interdisciplinary field devoted to understanding how biological systems implement social processes and behavior. Social neuroscience capitalizes on biological concepts and methods to inform and refine theories of social behavior, and it uses social and behavioral constructs and data to inform and refine theories of neural organization and function. We focus here on the progress and potential of social neuroscience in the area of mental health. Research in social neuroscience has grown dramatically in recent years. Among the most active areas of research we found are brain-imaging studies in normal children and adults; animal models of social behavior; studies of stroke patients; imaging studies of psychiatric patients; and research on social determinants of peripheral neural, neuroendocrine, and immunological processes. We also found that these areas of research are proceeding along largely independent trajectories. Our goals in this article are to review the development of this field, examine some currently promising approaches, identify obstacles and opportunities for future advances and integration, and consider how this research can inform work on the diagnosis and treatment of mental disorders.

Abstract
OBJECTIVE To examine the relationship of borderline personality disorder (BPD) to mood disorders by using data from the Collaborative Longitudinal Personality Disorders Study on the reciprocal interactions of BPD with both depressive and bipolar disorders over the course of 10 years. METHOD The study included 223 BPD patients with DSM-IV-defined co-occurring major depressive disorder (MDD) (n = 161), bipolar I disorder (n = 34), and bipolar II disorder (n = 28) who were reliably and prospectively assessed over a period of 10 years between 1997 and 2009. Proportional hazards regression analyses were used to assess the effects of improvement or worsening of BPD and mood disorders on each disorder's time to remission and time to relapse. RESULTS Borderline personality disorder and MDD had strong and statistically significant reciprocal effects, delaying each disorder's time to remission (BPD's effect on MDD, P = .0004; MDD's effect on BPD, P = .0002) and accelerating time to relapse (BPD's effect on MDD, P = .0410; MDD's effect on BPD, P = .0011), whereas BPD and the bipolar disorders were largely independent disorders except that bipolar II lengthened BPD's time to remission (P = .0085). CONCLUSIONS Borderline personality disorder and MDD interactions suggest overlap in their psychopathologies and argue for prioritizing the treatment of BPD. Borderline personality disorder and bipolar disorders appear to be independent disorders, underscoring the need to provide appropriate treatment for each.

[PMID: 24647406 DOI: 10.1016/j.janxdis.2014.01.005] [Citation(s) in RCA: 52] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2013] [Revised: 01/26/2014] [Accepted: 01/27/2014] [Indexed: 11/15/2022]
Abstract
This study aimed to determine the unique impact of PTSD symptoms, beyond other frequently examined factors on physical and mental health functioning in a sample of returning veterans. Assessments of 168 returning OEF/OIF veterans conducted an average of six months following return from deployment included measures of emotional disorders and the Short Form (36) Health Survey. Hierarchical multiple regressions revealed significant, unique contribution of Clinician-Administered PTSD Scale (CAPS) score above all other predictors in the model (demographics, severity of trauma exposure, physical injury, substance abuse and depressive symptoms), for both the physical (8%) and mental (6%) health aggregate scores, along with significant prediction of physical health (4-10%) and mental health (3-7%) subscale scores. The only other significant predictors were age for physical health scores, and depressive symptoms for mental health scores. PTSD criterion B (re-experiencing) symptoms uniquely predicted reduced physical health functioning and higher experience of bodily pain, while criterion D (hyperarousal) symptoms uniquely predicted lower feelings of energy/vitality and poorer perceptions of emotional health.

Abstract
This cross-sectional study examined the associations between neighborhood-level socioeconomic-status (NSES), and psychosocial functioning and personality pathology among 335 adults drawn from the Collaborative Longitudinal Personality Disorders Study. Participants belonged to four personality disorder (PD) diagnostic groups: Avoidant, Borderline, Schizotypal, and Obsessive Compulsive. Global functioning, social adjustment, and PD symptoms were assessed following a minimum two-year period of residential stability. Residence in higherrisk neighborhoods was associated with more PD symptoms and lower levels of functioning and social adjustment. These relationships were consistent after controlling for individual-level socioeconomic-status and ethnicity; however, the positive association between neighborhood-level socio-economic risk and PD symptoms was evident only at higher levels of individual-level socio-economic risk. Our findings identify NSES as a candidate for explaining some of the variability in symptoms and functioning among PD individuals.

Abstract
Researchers examining personality typologies of posttraumatic stress disorder (PTSD) have consistently identified 3 groups: low pathology, internalizing, and externalizing. These groups have been found to predict functional severity and psychiatric comorbidity. In this study, we employed Latent Profile Analysis to compare this previously established typology, grounded in temperament traits (negative emotionality; positive emotionality; constraint), to a novel typology rooted in interpersonal traits (dominance; warmth) in a sample of individuals with PTSD (n = 155). Using Schedule for Nonadaptive and Adaptive Personality (SNAP) traits to create latent profiles, the 3-group temperament model was replicated. Using Interpersonal Circumplex (IPC) traits to create latent profiles, we identified a 4-group solution with groups varying in interpersonal style. These models were nonredundant, indicating that the depiction of personality variability in PTSD depends on how personality is assessed. Whereas the temperament model was more effective for distinguishing individuals based on distress and comorbid disorders, the interpersonal model was more effective for predicting the chronicity of PTSD over the 10 year course of the study. We discuss the potential for integrating these complementary temperament and interpersonal typologies in the clinical assessment of PTSD.

Abstract
OBJECTIVE Research has demonstrated poor agreement between clinician-assigned personality disorder (PD) diagnoses and those generated by self-report questionnaires and semistructured diagnostic interviews. No research has compared prospectively the predictive validity of these methods. We investigated the convergence of these 3 diagnostic methods and tested their relative and incremental validity in predicting independent, multimethod assessments of psychosocial functioning performed prospectively over 5 years. METHOD Participants were 320 patients in the Collaborative Longitudinal Personality Disorders Study diagnosed with PDs by therapist, self-report, and semistructured interview at baseline. We examined the relative incremental validity of therapists' naturalistic ratings relative to these other diagnostic methods for predicting psychosocial functioning at 5-year follow-up. RESULTS Hierarchical linear regression analyses revealed that both the self-report questionnaire and semistructured interview PD diagnoses had significant incremental predictive validity over the PD diagnoses assigned by a treating clinician. Although, in some cases, the clinicians' ratings for individual PDs did have validity for predicting subsequent functioning, they did not generally provide incremental prediction beyond the other methods. These findings remained robust in a series of analyses restricted to a subsample of therapist ratings based on clinical contact of 1 year or greater. CONCLUSIONS These results from a large clinical sample echo previous research documenting limited agreement between clinicians' naturalistic PD diagnoses and those from self-report and semistructured interview methods. They extend prior work by providing the first evidence about the relative predictive validity of these different methods. Our findings challenge the validity of naturalistic PD diagnoses and suggest the use of structured diagnostic instruments.

Abstract
The co-occurrence of posttraumatic stress disorder (PTSD) and alcohol use disorders (AUDs) is well documented. Little is known about the factors that contribute to alcohol use and the development of AUDs among military personnel following deployment. The primary aim of this study was to examine trauma-related correlates of alcohol use in recently deployed Operation Enduring Freedom/Operation Iraqi Freedom veterans. Members of the Rhode Island National Guard and Army Reserves (N = 238) completed an in-person, initial assessment an average of 6 months postdeployment. Multiple regression analyses examined predictors of drinking outcomes (combat exposure, total PTSD symptoms, and PTSD symptom clusters) after accounting for gender, age, and history of AUD. Results indicated that total PTSD symptoms, but not combat exposure, significantly predicted alcohol use at the initial assessment. When PTSD symptom clusters were considered separately, reexperiencing symptoms (Cluster B) were the strongest predictor of total alcohol use (B = 3.58, p = .002) and heavy drinking episodes (B = 0.31, p = .005). Implications for these findings include early identification of risk factors that could lead to the development of AUDs, and the importance of integrated treatment approaches for co-occurring PTSD and AUD among veterans postdeployment.

Individuals with single versus multiple suicide attempts over 10years of prospective follow-up. Compr Psychiatry 2013; 54:238-42. [PMID: 22995448 PMCID: PMC3541431 DOI: 10.1016/j.comppsych.2012.07.062] [Citation(s) in RCA: 40] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2012] [Revised: 07/13/2012] [Accepted: 07/23/2012] [Indexed: 10/27/2022] Open
Abstract
BACKGROUND The study attempted to identify characteristics that differentiate multiple suicide attempters from single attempters in individuals with personality disorders (PDs) and/or major depression. METHOD Participants were 431 participants enrolled in the Collaborative Longitudinal Study of Personality Disorders from July 1996 to June 2008. Suicide attempts were assessed with the Longitudinal Interval Follow-up Evaluation at 6 and 12months, then yearly through 10years. Logistic regression was used to compare single attempters to multiple attempters on Axis I and II psychiatric disorders and personality trait variables. RESULTS Twenty-one percent of participants attempted suicide during the 10years of observation, with 39 (9.0%) reporting a single suicide attempt and 54 (12.5%) reporting multiple suicide attempts. Although no significant differences in were found in baseline Axis I disorders, multiple attempters were significantly more likely to meet criteria for borderline personality disorder and to have higher impulsivity scores than single attempters. CONCLUSION These results underscore the importance of considering both personality disorders and traits in the assessment of suicidality.

Abstract
OBJECTIVE This study compares the 10-year retest stability of normal traits, pathological traits, and personality disorder dimensions in a clinical sample. METHOD Ten-year rank-order stability estimates for the Revised NEO Personality Inventory, Schedule for Nonadaptive and Adaptive Personality, and Diagnostic Interview for DSM-IV Personality Disorders were evaluated before and after correcting for test-retest dependability and internal consistency in a clinical sample (N = 266). RESULTS Dependability-corrected stability estimates were generally in the range of.60-.90 for traits and.25-.65 for personality disorders. CONCLUSIONS The relatively lower stability of personality disorder symptoms may indicate important differences between pathological behaviors and relatively more stable self-attributed traits and imply that a full understanding of personality and personality pathology needs to take both traits and symptoms into account. The five-factor theory distinction between basic tendencies and characteristic adaptations provides a theoretical framework for the separation of traits and disorders in terms of stability in which traits reflect basic tendencies that are stable and pervasive across situations, whereas personality disorder symptoms reflect characteristic maladaptations that are a function of both basic tendencies and environmental dynamics.

Abstract
BACKGROUND Several conceptual models have been considered for the assessment of personality pathology in DSM-5. This study sought to extend our previous findings to compare the long-term predictive validity of three such models: the five-factor model (FFM), the schedule for nonadaptive and adaptive personality (SNAP), and DSM-IV personality disorders (PDs). METHOD An inception cohort from the Collaborative Longitudinal Personality Disorder Study (CLPS) was followed for 10 years. Baseline data were used to predict long-term outcomes, including functioning, Axis I psychopathology, and medication use. RESULTS Each model was significantly valid, predicting a host of important clinical outcomes. Lower-order elements of the FFM system were not more valid than higher-order factors, and DSM-IV diagnostic categories were less valid than dimensional symptom counts. Approaches that integrate normative traits and personality pathology proved to be most predictive, as the SNAP, a system that integrates normal and pathological traits, generally showed the largest validity coefficients overall, and the DSM-IV PD syndromes and FFM traits tended to provide substantial incremental information relative to one another. CONCLUSIONS DSM-5 PD assessment should involve an integration of personality traits with characteristic features of PDs.

Abstract
This study investigated the replicability of a previously proposed personality typology of posttraumatic stress disorder (PTSD, and explored stability of cluster membership over a 6-month period. Participants with current PTSD (n = 156) were drawn from the Collaborative Longitudinal Personality Disorders Study (CLPS). The CLPS project tracked a large sample of individuals who met criteria for 1 of 4 target diagnoses (borderline, schizotypal, avoidant, and obsessive-compulsive) and a contrast group of individuals who met criteria for depression but no personality disorder. A cluster analysis using scales from the Schedule of Nonadaptive and Adaptive Personality yielded 3 clusters: "internalizing," "externalizing," and "low pathology." Using K-means cluster analysis, the results did not replicate previous work. Using Ward's method, the hypothesized 3-cluster structure was confirmed at baseline but did not demonstrate temporal stability at 6 months.

Abstract
This study examines whether individuals with borderline personality disorder (BPD) would exhibit augmented emotional responses to picture stimuli after being challenged with an ideographic interpersonal conflict script. Participants were 24 adults diagnosed with BPD, 23 adults diagnosed with obsessive-compulsive personality disorder (OCPD), and 28 normal controls. Participants viewed emotionally evocative pictures before and after listening to the interpersonal script while a variety of physiological measures were recorded. Findings indicated that the interpersonal script was effective in eliciting enduring emotional responses from the BPD group relative to the control groups. However, despite the effectiveness of the interpersonal challenge task, there were no group differences in emotional responding to the affect eliciting stimuli. The findings underscore the complexities involved in examining emotional dysregulation in BPD in a laboratory setting.

Abstract
OBJECTIVE The identification of reliable predictors of course in major depressive disorder (MDD) has been difficult. Evidence suggests that the co-occurrence of personality pathology is associated with longer time to MDD remission. Interpersonal pathoplasticity, the mutually influencing nonetiological relationship between psychopathology and interpersonal traits, offers an avenue for examining specific personality vulnerabilities that may be associated with depressive course. METHOD This study examined 312 participants with and without a co-occurring personality disorder diagnosis who met criteria for a current MDD episode at baseline and who were followed for 10 years in the Collaborative Longitudinal Personality Disorders Study. RESULTS Latent profile analysis (LPA) identified 6 interpersonal groups (extraverted, dominant, arrogant, cold, submissive, and unassuming), and circular statistical profile analysis confirmed group interpersonal distinctiveness. No significant differences between groups were found in comorbid Axis I disorders or baseline MDD severity. Chronicity and functioning analyses found significantly greater chronicity and poorer functioning in individuals with a submissive interpersonal style over 10 years. CONCLUSIONS These findings support the relevance of interpersonal pathoplasticity in depressive course and that this heterogeneity has clinical significance. This study is the first to use LPA and circular profiles to examine interpersonal heterogeneity within a diagnostic group. The implications of these findings for therapeutic intervention, interpersonal functioning, and psychopathological course are discussed.

Self-harm subscale of the Schedule for Nonadaptive and Adaptive Personality (SNAP): predicting suicide attempts over 8 years of follow-up. J Clin Psychiatry 2011; 72:1522-8.

Abstract
OBJECTIVE We examined the predictive power of the self-harm subscale of the Schedule for Nonadaptive and Adaptive Personality (SNAP) to identify suicide attempters in the Collaborative Longitudinal Study of Personality Disorders (CLPS). METHOD The SNAP, a self-report personality inventory, was administered to 733 CLPS participants at baseline, of whom 701 (96%) had at least 6 months of follow-up data. Cox proportional hazards regression analyses were performed to examine the SNAP-self-harm subscale (SNAP-SH) in predicting the 129 suicide attempters over 8 years of follow-up. Possible moderators of prediction were examined, including borderline personality disorder, major depressive disorder (MDD), and substance use disorder. We also compared baseline administration of the SNAP-SH to subsequent administrations more proximal to the suicide attempt, and to a higher-order SNAP-negative temperament (SNAP-NT) subscale. Receiver operating characteristic analyses were conducted using suicide attempts (n = 58) over the first year of follow-up to provide reference points for sensitivity and specificity. RESULTS The SNAP-SH demonstrated good predictive power for suicide attempts (hazard ratio = 1.28, P < .001) and appeared relatively consistent across borderline personality disorder, MDD, and substance use disorder diagnoses. Using more proximal scores did not increase predictive power. The SNAP-SH compared favorably to the predictive power of the higher-order SNAP-NT. Receiver operating characteristic analyses indicate several cutoff scores on the SNAP-SH that yield moderate to high sensitivity and specificity for predicting suicide attempts over the first year of follow-up. CONCLUSIONS The SNAP-SH may be a useful screening instrument for risk of suicide attempts in nonpsychotic psychiatric patients.

Abstract
Personality traits may provide underlying risk factors for and/or sequelae to substance use disorders (SUDs). In this study Schedule for Nonadaptive and Adaptive Personality (SNAP) traits were compared in a clinical sample (N=704, age 18-45) with current, past, or no historical alcohol or non-alcohol substance use disorders (AUD and NASUD) as assessed by DSM-IV semi-structured interview. Results corroborated previous research in showing associations of negative temperament and disinhibition to SUD, highlighting the importance of these traits for indicating substance use proclivity or the chronic effects of substance use. Certain traits (manipulativeness, self-harm, disinhibition, and impulsivity for AUD, and disinhibition and exhibitionism for NASUD) were higher among individuals with current relative to past diagnoses, perhaps indicating concurrent effects of substance abuse on personality. The positive temperament characteristics detachment and entitlement distinguished AUDs and NASUDs, respectively, perhaps clarifying why this higher order trait tends to show limited relations to SUD generally. These findings suggest the importance of systematically integrating pathological and normative traits in reference to substance-related diagnosis.

Abstract
Findings from several large-scale, longitudinal studies over the last decade have challenged the long-held assumption that personality disorders (PDs) are stable and enduring. However, the findings, including those from the Collaborative Longitudinal Personality Disorders Study (CLPS; Gunderson et al., 2000), rely primarily on results from semistructured interviews. As a result, less is known about the stability of PD scores from self-report questionnaires, which differ from interviews in important ways (e.g., source of the ratings, item development, and instrument length) that might increase temporal stability. The current study directly compared the stability of the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) PD constructs assessed via the Schedule for Nonadaptive and Adaptive Personality (SNAP-2; Clark, Simms, Wu, & Casillas, in press) with those from the Diagnostic Interview for DSM-IV Personality Disorders (Zanarini, Frankenburg, Sickel, & Yong, 1996) over 2 years in a sample of 529 CLPS participants. Specifically, we compared dimensional and categorical representations from both measures in terms of rank-order and mean-level stability. Results indicated that the dimensional scores from the self-report questionnaire had significantly greater rank-order (mean r=.69 vs. .59) and mean-level (mean d=0.21 vs. 0.30) stability. In contrast, categorical diagnoses from the two measures evinced comparable rank-order (mean κ=.38 vs. .37) and mean-level stability (median prevalence rate decrease of 3.5% vs. 5.6%). These findings suggest the stability of PD constructs depends at least partially on the method of assessment and are discussed in the context of previous research and future conceptualizations of personality pathology.

Abstract
Despite a general consensus that dimensional models are superior to the categorical representations of personality disorders in DSM-IV, proposals for how to depict personality pathology dimensions vary substantially. One important question involves how to separate clinical severity from the style of expression through which personality pathology manifests. This study empirically distinguished stylistic elements of personality pathology symptoms from the overall severity of personality disorder in a large, longitudinally assessed clinical sample (N = 605). Data suggest that generalized severity is the most important single predictor of current and prospective dysfunction, but that stylistic elements also indicate specific areas of difficulty. Normative personality traits tend to relate to the general propensity for personality pathology, but not stylistic elements of personality disorders. Overall, findings support a three-stage diagnostic strategy involving a global rating of personality disorder severity, ratings of parsimonious and discriminant valid stylistic elements of personality disorder, and ratings of normative personality traits.

Abstract
BACKGROUND This study prospectively examined the natural clinical course of six anxiety disorders over 7 years of follow-up in individuals with personality disorders (PDs) and/or major depressive disorder. Rates of remission, relapse, new episode onset and chronicity of anxiety disorders were examined for specific associations with PDs. METHOD Participants were 499 patients with anxiety disorders in the Collaborative Longitudinal Personality Disorders Study, who were assessed with structured interviews for psychiatric disorders at yearly intervals throughout 7 years of follow-up. These data were used to determine probabilities of changes in disorder status for social phobia (SP), generalized anxiety disorder (GAD), obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), panic disorder and panic disorder with agoraphobia. RESULTS Estimated remission rates for anxiety disorders in this study group ranged from 73% to 94%. For those patients who remitted from an anxiety disorder, relapse rates ranged from 34% to 67%. Rates for new episode onsets of anxiety disorders ranged from 3% to 17%. Specific PDs demonstrated associations with remission, relapse, new episode onsets and chronicity of anxiety disorders. Associations were identified between schizotypal PD with course of SP, PTSD and GAD; avoidant PD with course of SP and OCD; obsessive-compulsive PD with course of GAD, OCD, and agoraphobia; and borderline PD with course of OCD, GAD and panic with agoraphobia. CONCLUSIONS Findings suggest that specific PD diagnoses have negative prognostic significance for the course of anxiety disorders underscoring the importance of assessing and considering PD diagnoses in patients with anxiety disorders.
