A randomized clinical trial comparing Interpersonal Psychotherapy with Prolonged Exposure for the treatment of PTSD in veterans.

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.

A randomized trial of brief couple therapy for PTSD and relationship satisfaction.

OBJECTIVE: This three-arm randomized trial tested a brief version of cognitive-behavioral conjoint therapy (bCBCT) delivered in two modalities compared to couples' psychoeducation in a sample of U.S. veterans with posttraumatic stress disorder (PTSD) and their intimate partners. METHOD: Couples were randomized to receive (a) in-person, office-based bCBCT (OB-bCBCT), (b) bCBCT delivered via home-based telehealth (HB-bCBCT), or (c) an in-person psychoeducation comparison condition (PTSD family education [OB-PFE]). Primary outcomes were clinician-assessed PTSD severity (Clinician Administered PTSD Scale), self-reported psychosocial functioning (Brief Inventory of Psychosocial Functioning), and relationship satisfaction (Couples Satisfaction Index) at posttreatment and through 6-month follow-up. RESULTS: PTSD symptoms significantly decreased by posttreatment with all three treatments, but compared to PFE, PTSD symptoms declined significantly more for veterans in OB-bCBCT (between-group d = 0.59 [0.17, 1.01]) and HB-bCBCT (between-group d = 0.76 [0.33, 1.19]) treatments. There were no significant differences between OB-bCBCT and HB-bCBCT. Psychosocial functioning and relationship satisfaction showed significant small to moderate improvements, with no differences between treatments. All changes were maintained through 6-month follow-up. CONCLUSIONS: A briefer, more scalable version of CBCT showed sustained effectiveness relative to an active control for improving PTSD symptoms when delivered in-person or via telehealth. Both bCBCT and couples' psychoeducation improved psychosocial and relational outcomes. These results could have a major impact on PTSD treatment delivery within large systems of care where access to brief, evidence-based PTSD treatments incorporating family members are needed.

Rationale, design, and methods of a two-site randomized controlled trial: Comparative effectiveness of two treatments for posttraumatic stress disorder in veterans.

PTSD is associated with serious problems in interpersonal functioning, including higher rates of marital conflict and divorce, disrupted relationships with family and friends, estrangement from others and social isolation. Cognitive behavioral and trauma focused treatments are effective for treating PTSD symptoms, but a substantial proportion of individuals, particularly veterans, with PTSD, do not engage, complete, or fully respond to these treatments, and the effects of these treatments on interpersonal functioning are unknown. There is a critical need for alternative treatments with established efficacy, and for treatments that directly address problems in relationship functioning. Interpersonal Psychotherapy for PTSD (IPT-PTSD) is a promising candidate for such a treatment. This paper describes the rationale, design, and methods of the first randomized controlled equivalence trial comparing IPT-PTSD with a first-line gold standard treatment for PTSD (Prolonged Exposure; PE) in the treatment of PTSD in veterans. Both treatments include up to 12 weekly individual sessions. Assessments were conducted at baseline, following sessions four and eight, end of treatment, and 3 and 6 months post-treatment. Primary hypotheses are that IPT-PTSD will be statistically equivalent to PE in reducing the severity of PTSD symptoms, and superior to PE in improving interpersonal functioning. Secondary hypotheses propose that IPT will be superior to PE in improving overall social adjustment and quality of life, and in reducing suicidal ideation. Findings from this study have the potential to improve treatment options for veterans struggling with PTSD and interpersonal problems.

Design of a randomized superiority trial of a brief couple treatment for PTSD.

Interpersonal difficulties are common among veterans with posttraumatic stress disorder (PTSD) and are associated with poorer treatment response. Treatment outcomes for PTSD, including relationship functioning, improve when partners are included and engaged in the therapy process. Cognitive-behavioral conjoint therapy for PTSD (CBCT) is a manualized 15-session intervention designed for couples in which one partner has PTSD. CBCT was developed specifically to treat PTSD, engage a partner in treatment, and improve interpersonal functioning. However, recent research suggests that an abbreviated CBCT protocol may lead to sufficient gains in PTSD and relationship functioning, and yield lower dropout rates. Likewise, many veterans report a preference for receiving psychological treatments through clinical videoteleconferencing (CVT) rather than traditional face-to-face modalities that require travel to VA clinics. This manuscript describes the development and implementation of a novel randomized controlled trial (RCT) that examines the efficacy of an abbreviated 8-session version of CBCT ("brief CBCT," or B-CBCT), and compares the efficacy of this intervention delivered via CVT to traditional in-person platforms. Veterans and their partners were randomized to receive B-CBCT in a traditional Veterans Affairs office-based setting (B-CBCT-Office), CBCT through CVT with the veteran and partner at home (B-CBCT-Home), or an in office-delivered, couple-based psychoeducation control condition (PTSD Family Education). This study is the first RCT designed to investigate the delivery of B-CBCT specifically to veterans with PTSD and their partners, as well as to examine the delivery of B-CBCT over a CVT modality; findings could increase access to care to veterans with PTSD and their partners.

The incorporation of emotion-regulation skills into couple- and family-based treatments for post-traumatic stress disorder.

Post-traumatic stress disorder (PTSD) is a disabling, potentially chronic disorder that is characterized by re-experience and hyperarousal symptoms as well as the avoidance of trauma-related stimuli. The distress experienced by many veterans of the Vietnam War and their partners prompted a strong interest in developing conjoint interventions that could both alleviate the core symptoms of PTSD and strengthen family bonds. We review the evolution of and evidence base for conjoint PTSD treatments from the Vietnam era through the post-911 era. Our review is particularly focused on the use of treatment strategies that are designed to address the emotions that are generated by the core symptoms of the disorder to reduce their adverse impact on veterans, their partners and the relationship. We present a rationale and evidence to support the direct incorporation of emotion-regulation skills training into conjoint interventions for PTSD. We begin by reviewing emerging evidence suggesting that high levels of emotion dysregulation are characteristic of and predict the severity of both PTSD symptoms and the level of interpersonal/marital difficulties reported by veterans with PTSD and their family members. In doing so, we present a compelling rationale for the inclusion of formal skills training in emotional regulation in couple-/family-based PTSD treatments. We further argue that increased exposure to trauma-related memories and emotions in treatments based on learning theory requires veterans and their partners to learn to manage the uncomfortable emotions that they previously avoided. Conjoint treatments that were developed in the last 30 years all acknowledge the importance of emotions in PTSD but vary widely in their relative emphasis on helping participants to acquire strategies to modulate them compared to other therapeutic tasks such as learning about the disorder or disclosing the trauma to a loved one. We conclude our review by describing two recent innovative treatments for PTSD that incorporate a special emphasis on emotion-regulation skills training in the dyadic context: structured approach therapy (SAT) and multi-family group for military couples (MFG-MC). Although the incorporation of emotion-regulation skills into conjoint PTSD therapies appears promising, replication and comparison to cognitive-behavioral approaches is needed to refine our understanding of which symptoms and veterans might be more responsive to one approach versus others.

Structured Approach Therapy for Combat-Related PTSD in Returning U.S. Veterans: Complementary Mediation by Changes in Emotion Functioning.

To address the impact of combat-related posttraumatic stress disorder (PTSD) on U.S. Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) veterans, the investigators developed a 12-session manualized PTSD treatment for couples called structured approach therapy (SAT). A randomized controlled trial had shown that 29 OEF/OIF veterans with combat-related PTSD who had participated in SAT showed significantly greater reductions in PTSD compared to 28 veterans receiving a 12-session PTSD family education intervention (Sautter, Glynn, Cretu, Senturk, & Vaught, 2015). We conducted supplemental follow-up and mediation analyses, which tested the hypothesis that changes in emotion functioning play a significant role in the decreases in PTSD symptoms primarily observed in veterans who had received SAT. Veterans assigned to the SAT condition showed significantly greater decreases than those assigned to PTSD family education in emotion regulation problems (p < .001, Cohen's f(2) = .18) and fear of intense emotions (p < .001, Cohen's f(2) = .152). Decreases in both emotion regulation problems (mediated effect:ab̂= .36), and fear of intense emotions (mediated effect:ab̂ = .24) were found to be complementary mediators of reductions in PTSD symptoms greater with SAT. These findings suggest that SAT may aid veterans in improving their ability to regulate trauma-related emotions.

Efficacy of structured approach therapy in reducing PTSD in returning veterans: A randomized clinical trial.

The U.S. military deployed in support to Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF) show high rates of posttraumatic stress disorder (PTSD) and relationship, partner, and parenting distress. Given the pervasive effect of combat-related PTSD on returning veterans and its effect on their loved ones, the investigators have developed a couples-based treatment, structured approach therapy (SAT), to reduce PTSD while simultaneously decreasing relationship and partner distress. This study presents treatment outcome data measuring PTSD and relationship outcomes from a randomized clinical trial (RCT) comparing SAT, a manualized 12-session novel couples-based PTSD treatment, to a manualized 12-session couples-based educational intervention (PTSD Family Education [PFE]). Data were collected from 57 returning veterans meeting Diagnostic and Statistical Manual of Mental Disorders (fourth edition, text revision; DSM-IV-TR) criteria for PTSD and their cohabiting partners; data collection was scheduled for pretreatment, posttreatment, and 3-month follow-up. Findings from an intent-to-treat analysis revealed that veterans receiving SAT showed significantly greater reductions in self-rated (PTSD Checklist; p < .0006) and Clinician-Administered PTSD Scale (CAPS)-rated PTSD (p < .0001) through the 3-month follow-up compared with veterans receiving PFE; 15 of 29 (52%) veterans receiving SAT and 2 of 28 (7%) receiving PFE no longer met DSM-IV-TR criteria for PTSD. Furthermore, SAT was associated with significant improvements in veteran relationship adjustment, attachment avoidance, and state anxiety. Partners showed significant reductions in attachment anxiety. This couples-based treatment for combat-related PTSD appears to have a strong therapeutic effect on combat-related PTSD in recently returned veterans.

A couple-based approach to the reduction of PTSD avoidance symptoms: preliminary findings.

This study reports preliminary findings regarding the feasibility and efficacy of a novel couple-based treatment, named Strategic Approach Therapy (SAT), for reducing avoidance symptoms of posttraumatic stress disorder (PTSD). Six male Vietnam combat veterans diagnosed with PTSD and their cohabitating marital partners participated in 10 weeks of SAT treatment. Self-report, clinician ratings, and partner ratings of PTSD symptoms were obtained before the first session and after the tenth session of treatment. Veterans reported statistically significant reductions in self-reported, clinician-rated, and partner-rated effortful avoidance, emotional numbing, and overall PTSD severity. These data indicate that SAT offers promise as an effective treatment for PTSD avoidance symptoms.

Psychological distress and burden among female partners of combat veterans with PTSD.

Psychological distress among cohabitating female partners of combat veterans with posttraumatic stress disorder (PTSD) was examined in a cross-sectional study using a modified version of the Health Belief Model. A convenience sample of 89 cohabitating female partners of male veterans in outpatient PTSD treatment was interviewed by telephone using a structured interview. Partners endorsed high levels of psychological distress with elevations on clinical scales at or exceeding the 90th percentile. Severe levels of overall psychological distress, depression, and suicidal ideation were prevalent among partners. Multivariate analyses revealed that perceived threat, recent mental health treatment, and level of involvement with veterans predicted global partner psychological distress. Partner burden was predicted by partner self-efficacy, perceived threat, barriers to mental health treatment, and partner treatment engagement. These findings are compelling since they demonstrate that partners of veterans with combat-related PTSD experience significant levels of emotional distress that warrant clinical attention. Psychological distress and partner burden were each associated with a unique combination of predictors, suggesting that although these constructs are related, they have distinct correlates and potentially different implications within the family environment. Future research should examine these constructs separately using causal modeling analyses to identify modifiable targets for interventions to reduce psychological distress among partners of individuals with PTSD.

Corticotropin-releasing factor in posttraumatic stress disorder (PTSD) with secondary psychotic symptoms, nonpsychotic PTSD, and healthy control subjects.

BACKGROUND: Recent studies have reported a high comorbidity between posttraumatic stress disorder (PTSD) and psychotic symptoms, and it has been hypothesized that PTSD with comorbid psychosis is a severe form of PTSD. Few studies have examined the neurobiology of PTSD with comorbid psychosis. If PTSD with secondary psychotic symptoms (PTSD-SP) is a severe form of PTSD, then it might be expected to show more extreme perturbations in the neuroendocrine patterns that characterize PTSD. METHODS: Patients with PTSD with secondary psychotic symptoms (PTSD-SP), PTSD without psychosis, and healthy comparison subjects were compared for differences in cerebrospinal fluid concentrations of corticotropin-releasing factor (CRF) and somatotropin-release-inhibiting hormone (SRIF). RESULTS: The PTSD-SP subjects had significantly higher mean levels of CRF than either the PTSD or control subjects (p <.01). The three groups showed similar SRIF levels. CONCLUSIONS: These data implicate abnormalities in the secretion of CRF with the production of secondary psychotic symptoms in PTSD. This finding supports the validity of PTSD-SP as a PTSD subtype and as a severe form of PTSD.

Differences in smooth pursuit eye movement between posttraumatic stress disorder with secondary psychotic symptoms and schizophrenia.

Studies show high comorbidity between post-traumatic stress disorder and psychotic symptoms. Despite this fact, there has been only one published study of the neurobiology of this enigmatic disorder. This preliminary study examines the relationship between psychotic symptoms in post-traumatic stress disorder (PTSD) and schizophrenia by measuring smooth pursuit eye movement (SPEM) in subjects with PTSD and secondary psychotic symptoms, schizophrenia, and healthy controls. The results show that PTSD with secondary psychotic symptoms is associated with a SPEM deficit that is different from the SPEM deficit associated with schizophrenia.

Family history study of posttraumatic stress disorder with secondary psychotic symptoms.

OBJECTIVE: A family history approach was used to determine if posttraumatic stress disorder (PTSD) with secondary psychotic symptoms was associated with a familial vulnerability to schizophrenia and other psychoses. METHOD: Family history methods were used to compare rates of familial psychopathology in the first-degree relatives of three proband groups: 1) patients with DSM-IV PTSD with secondary psychotic symptoms, 2) patients with DSM-IV PTSD without psychotic symptoms, and 3) healthy matched comparison subjects. RESULTS: PTSD with secondary psychotic symptoms was not associated with an excess of familial psychotic disorder but was associated with a higher morbid risk for depression. CONCLUSIONS: PTSD with secondary psychotic symptoms was not associated with familial psychosis, suggesting it does not reflect the presence of an underlying psychotic disorder.
