Introduction to the special section on social relationships and posttraumatic stress disorder treatment: Harnessing the power of significant relationships.

This article introduces the special section in the Journal of Traumatic Stress focused on social relationships and their connection to treatment among individuals with posttraumatic stress disorder (PTSD). Interpersonal relationships have the potential to influence treatment-seeking, retention, and outcomes. For individuals with PTSD, social relationships have long been understood to be intimately and bidirectionally tied to symptom levels. In light of somewhat modest rates of treatment response to current first-line interventions for PTSD, there is growing interest in engaging these relationships, as well as relationship-relevant beliefs and behaviors, to enhance PTSD treatment. This introductory article frames the rationale for examining these social factors to better understand and improve treatments and provides an overview of the collection of articles contained herein.

Family Involvement in PTSD Treatment: Perspectives from a Nationwide Sample of Veterans Health Administration Clinicians.

Social support is bidirectionally linked to symptoms of posttraumatic stress disorder (PTSD). Evidence suggests that family involvement in veterans' mental health treatment is desired by both veterans and family members, and that such involvement has the potential to improve treatment outcomes. However, rates of family involvement are low in the Veterans Health Administration (VHA). We sought to understand VHA clinicians' perspectives on family involvement in PTSD treatment by conducting qualitative interviews with 31 providers at 10 VHA facilities across the U.S. The i-PARIHS framework was used to guide the interviews and analysis, and several major themes were identified. All clinicians reported that they at least occasionally offered family-inclusive sessions, and they frequently referenced both the influence of family behaviors or attitudes on veterans' functioning, and also how veterans' symptoms could cause tremendous disruption in the family. Clinicians' past experience with supervised family- or couple-based work strongly influenced their current comfort with family-inclusive sessions. Multiple potential avenues exist to support increased family involvement in PTSD treatment in VHA.

Seeking to Understand the Conditions Under Which Exposure-Based Writing Therapy for Posttraumatic Stress Disorder is an Effective Approach: A Commentary on Dawson et al. (2020).

Exposure-based writing interventions for posttraumatic stress disorder (PTSD) have shown promise when compared with waitlist conditions, placebo writing control conditions, and evidence-based, trauma-focused treatments. Recently, Dawson et al. (2020) conducted a systematic review and meta-analysis to examine existing published randomized controlled trials investigating exposure-based writing interventions. The findings were encouraging; however, the studies included in the meta-analysis had a high degree of methodological heterogeneity. Our own work examining exposure-based writing as an intervention for PTSD has demonstrated that methodological differences in the structure of exposure-based writing can have a meaningful impact on treatment outcome. Accordingly, we urge caution in interpreting the meta-analysis findings reported by Dawson and colleagues and encourage investigation into better understanding the mechanisms underlying exposure-based writing interventions to further propel this important area of work.

The Use of a Brief Family Intervention to Reduce Dropout Among Veterans in Individual Trauma-Focused Treatment: A Randomized Controlled Trial.

Dropout from trauma-focused treatment for posttraumatic stress disorder (PTSD) represents a daunting challenge for the field, particularly among military and veteran samples. Family involvement may help to increase the effectiveness of PTSD treatment while also improving retention. We tested a two-session brief family intervention (BFI) protocol delivered as an adjunct to individual trauma-focused treatment among a sample of 20 veteran-family member dyads (N = 40). Willingness to participate in the family-inclusive protocol was high, with over 85% of veterans and family members who were screened agreeing to take part. All enrolled veterans were beginning a course of either cognitive processing therapy (CPT) or prolonged exposure (PE), delivered in outpatient Veterans Affairs clinics. Family members were randomized to either receive or not receive the BFI from study clinicians. In the BFI condition, 20.0% of veterans dropped out of CPT/PE before the 16-week study end; the remainder were either still attending on-protocol sessions or had completed the full protocol. In the control condition, 40.0% of veterans dropped out of CPT/PE before the end of the study. Observed significant, large-magnitude decreases in PTSD symptoms over time did not differ by condition, ESsg range = -1.12 to -2.04. Accommodation did not significantly decrease over time in either condition, ESsg range = 0.18 to -0.98. The BFI represents a promising option for veterans, family members, and clinicians who are seeking a brief, feasible, narrowly focused method for incorporating families into veterans' individual trauma-focused therapy and potentially reducing the rate of dropout.

Development and initial testing of a brief adjunctive intervention for family members of veterans in individual PTSD treatment.

Family involvement in the treatment of posttraumatic stress disorder (PTSD) among veterans has the potential to improve treatment retention and outcomes. Current protocols that incorporate family members into treatment tend to involve at least 15 sessions, and none are designed to complement Cognitive Processing Therapy (CPT) or Prolonged Exposure (PE), the two most widely used and heavily promoted evidence-based PTSD therapies in the Veterans Affairs (VA) healthcare system. The current paper describes the development and initial feasibility and acceptability of a Brief Family Intervention (the BFI) designed to be delivered as an adjunct to veterans' individual CPT/PE. The BFI focuses on providing psychoeducation about PTSD and treatment, building family member support for treatment, and reducing family symptom accommodation. A detailed review of the treatment structure and activities is provided, and qualitative data from four dyads (veterans and their spouses/significant others) at baseline and post-intervention are presented. Veterans and partners reported positive responses to the program and were enthusiastic about its utility. Larger randomized controlled studies will be needed to determine the protocol's efficacy and effectiveness.

Long-term treatment gains of a brief exposure-based treatment for PTSD.

BACKGROUND: Written exposure therapy (WET) is a 5-session PTSD treatment that may address barriers in treatment for posttraumatic stress disorder (PTSD) given its brevity and tolerability. A recent study found outcomes for WET were non-inferior to outcomes from Cognitive Processing Therapy (CPT) through 36 weeks from first treatment session (Sloan, Marx, Lee, & Resick, 2018); the current study examined whether treatment gains were maintained through 60 weeks from first session, and also evaluated both treatments' effect on depressive symptoms. METHODS: The study enrolled 126 individuals with PTSD randomized to WET or CPT. Assessments were conducted at baseline and 6, 12, 24, 36, and 60 weeks following the first treatment session. PTSD diagnosis and symptom severity were determined via the Clinician Administered PTSD Scale for DSM-5 (CAPS-5), and depression symptoms were assessed using the Beck Depression Inventory-2. RESULTS: WET remained non-inferior to CPT through the 60 week assessment; the groups had a difference of less than 3 points in their total CAPS-5 scores, and within-condition effects on PTSD were large (WET d = 1.23; CPT d = 1.38). Both treatments significantly reduced depressive symptoms over the 60 week study, with the CPT group experiencing a more rapid decrease. The between-condition effect of treatment on depression was small (d = .19). CONCLUSIONS: WET is a treatment that is non-inferior to CPT with regard to PTSD symptoms, with treatment effects that are long-lasting. Additionally, both WET and CPT demonstrated substantial effects on depressive symptoms. WET should be considered a good option for PTSD treatment.

Alliance across group treatment for veterans with posttraumatic stress disorder: The role of interpersonal trauma and treatment type.

OBJECTIVE: Examine initial levels and pattern of change of alliance in group treatment for posttraumatic stress disorder (PTSD) for veterans. METHOD: One hundred and seventy-eight male veterans with PTSD were recruited for this study. Participants were randomly assigned to either group cognitive behavioral therapy (GCBT) or to group present-centered therapy (GPCT). Alliance with fellow group members was assessed every other session throughout the group (total of seven assessments). Hierarchical linear modeling was used to determine whether treatment condition or index trauma type (interpersonal or non-interpersonal) impacted initial levels of alliance or change in alliance over time. RESULTS: Alliance increased significantly throughout treatment in both conditions. The presence of an interpersonal index event, compared to a non-interpersonal index event, did not significantly impact either initial levels of alliance or change in alliance over time. Participants in the GCBT condition experienced significantly greater growth in alliance over time compared to those in the GPCT condition (p > .05), but did not have significantly different initial alliance ratings. CONCLUSIONS: The components and focus of the GCBT treatment may have facilitated more rapid bonding among members. Interpersonal traumatic experience did not negatively impact group alliance.

The Association Between Peritraumatic Dissociation and PTSD Symptoms: The Mediating Role of Negative Beliefs About the Self.

Peritraumatic dissociation, a term used to describe a complex array of reactions to trauma, including depersonalization, derealization, and emotional numbness, has been associated with posttraumatic stress disorder (PTSD) symptoms across a number of studies. Cognitive theory suggests that interpretations of traumatic events and reactions underlie the persistence of PTSD. The present study examined the associations among peritraumatic dissociation, posttraumatic cognitions, and PTSD symptoms in a group of trauma-exposed adults (N = 169). Results indicated that, after accounting for overall symptom severity and current dissociative tendencies, peritraumatic dissociation was significantly predictive of negative beliefs about the self (R2 = .06, p < .001). Other categories of maladaptive posttraumatic cognitions did not show a similar relationship (R2 = .01 to .02, nonsignificant). Negative thoughts about the self partially mediated the association between peritraumatic dissociation and PTSD severity (completely standardized indirect effect = .25). These findings lend support to cognitive theories of PTSD and point to an important area for clinical intervention.

CBT and the future of personalized treatment: a proposal.

Over the past several decades, the diagnosis of mental disorders has been characterized by classifying psychopathology into as many discrete diagnoses as can be reliability identified (e.g., APA, 2013). There is increasing evidence, however, that this approach to diagnosis may come at the expense of validity as trivial symptom-level differences are emphasized with little regard for common core mechanisms. Traditionally, cognitive-behavioral (CBT) approaches to treating psychopathology have followed a diagnosis-specific approach such that unique protocols have been developed for most disorders. Recent advances in CBT have suggested that targeting transdiagnostic mechanisms responsible for the development and maintenance of a wider range of psychopathology may be a more efficient approach to treatment than addressing disorder symptoms themselves. In order to create a more personalized treatment package, we propose establishing a profile for each patient that quantifies dysfunction in terms of empirically-supported underlying mechanisms; we further suggest that data from this profile be used to select CBT modules specific to the core mechanisms maintaining an individual patient's symptoms.

Brief family involvement enhances veteran homework quality during trauma-focused psychotherapy.

OBJECTIVE: Homework has been shown to improve outcomes in cognitive-behavioral therapy, though less is known about the importance of homework during trauma-focused psychotherapy. Similarly, prior research suggests family context plays a key role in posttraumatic stress disorder (PTSD)-related distress and treatment engagement. One potential way that families can facilitate better treatment outcomes is by promoting homework engagement. This study examined the impact of a brief family intervention (BFI) for PTSD toward this aim. We hypothesized that veterans with PTSD whose family members (FMs) received the BFI would have better homework completion and quality than those who did not receive the BFI. METHOD: This mixed-methods analysis examined 24 veteran-family dyads enrolled in a randomized clinical trial examining the BFI. All veterans were currently engaged in trauma-focused psychotherapy. Each veteran's clinician rated their homework quality and completion after each therapy session. A subset of dyads also completed semistructured interviews posttreatment. A rapid qualitative analysis approach was used to examine themes in shifting family behavior post-BFI. RESULTS: Quantitative analyses yielded partial support for our hypotheses: those in the BFI condition had significantly higher clinician-rated homework quality. While participants in the BFI condition had a higher homework completion rate, this difference did not reach statistical significance. Qualitative analyses suggested that the BFI prompted meaningful discussions about PTSD and increased FMs' use of supportive (rather than accommodative) behavior when responding to PTSD-related distress. CONCLUSIONS: Involving FMs in PTSD treatment appears to shift the family context in a manner that improves homework quality in veterans. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

The significant others' responses to trauma scale (SORTS): applying factor analysis and item response theory to a measure of PTSD symptom accommodation.

Background: Symptom accommodation by family members (FMs) of individuals with posttraumatic stress disorder (PTSD) includes FMs' participation in patients' avoidance/safety behaviours and constraining self-expression to minimise conflict, potentially maintaining patients' symptoms. The Significant Others' Responses to Trauma Scale (SORTS) is the only existing measure of accommodation in PTSD but has not been rigorously psychometrically tested.Objective: We aimed to conduct further psychometric analyses to determine the factor structure and overall performance of the SORTS. Method: We conducted exploratory and confirmatory factor analyses using a sample of N = 715 FMs (85.7% female, 62.1% White, 86.7% romantic partners of individuals with elevated PTSD symptoms).Results: After dropping cross-loading items, results indicated good fit for a higher-order model of accommodation with two factors: an anger-related accommodation factor encompassed items related largely to minimising conflict, and an anxiety-related accommodation factor encompassed items related primarily to changes to the FM's activities. Accommodation was positively related to PTSD severity and negatively related to relationship satisfaction, although the factors showed somewhat distinct associations. Item Response Theory analyses indicated that the scale provided good information and robust coverage of different accommodation levels.Conclusions: SORTS data should be analysed as both a single score as well as two factors to explore the factors' potential differential performance across treatment and relationship outcomes.

We examined the Significant Others' Responses to Trauma Scale (SORTS), a measure of symptom accommodation in PTSD, among a large sample of family members.As measured by the SORTS, accommodation in PTSD could be broken down into two aspects: anger-related accommodation and anxiety-related accommodation.Accommodation was positively related to PTSD severity and negatively related to relationship satisfaction.

Thought-action fusion across anxiety disorder diagnoses: specificity and treatment effects.

Thought-action fusion (TAF) is a cognitive error that has been frequently investigated within the context of obsessive-compulsive disorder (OCD). However, evidence suggests that this error may also be present in disorders other than OCD, indicating that TAF is related to higher order factors rather than a specific diagnosis. We explored TAF in a sample of patients with mixed diagnoses undergoing treatment with a transdiagnostic CBT protocol. Elevated TAF levels at baseline were not specific to patients with OCD. However, the presence of any generalized anxiety disorder (GAD) diagnosis was unexpectedly the strongest predictor of likelihood TAF. Likelihood TAF, a particular component of TAF, was reduced after transdiagnostic treatment, and this reduction was not affected by the presence of a GAD diagnosis. Results indicate that TAF is responsive to treatment and should be assessed and, perhaps, treated in disorders beyond OCD.

Intolerance of uncertainty: a common factor in the treatment of emotional disorders.

UNLABELLED: Intolerance of uncertainty (IU) is a characteristic predominantly associated with generalized anxiety disorder (GAD); however, emerging evidence indicates that IU may be a shared element of emotional disorders. AIMS: This study aimed to examine IU across diagnostic categories, change in IU during transdiagnostic treatment, and the relationship between change in IU and treatment outcome. METHOD: Patients diagnosed with heterogeneous anxiety and depressive disorders received up to 18 weeks of a transdiagnostic cognitive-behavioral therapy intervention. Patient self-reported IU and self-report and clinician-rated symptom/functioning measures were administered at pretreatment and posttreatment. RESULTS: When controlling for negative affectivity, IU correlated with measures of depressive symptoms and worry severity at pretreatment. Patients with GAD and panic disorder exhibited the highest pretreatment IU scores, yet IU scores did not differ significantly based on the presence or absence of a specific diagnosis. A significant decrease in IU was observed, and change in IU was related to reduced anxiety and depressive symptom levels at posttreatment across diagnostic categories. DISCUSSION: Change in IU can be observed across problem areas in transdiagnostic treatment and such change is correlated with treatment outcome.

Women veterans' attitudes toward family involvement in PTSD treatment: A mixed-methods examination.

Family member (FM) involvement in treatment for posttraumatic stress disorder (PTSD) has the potential to enhance veterans' sense of support and connection and reduce treatment dropout. Little is known, however, about women veterans' preferences, concerns, and goals regarding FM involvement in PTSD treatment. The study employed a mixed-methods approach consisting of surveys (n = 143) and interviews (n = 10) with women veterans seeking treatment for PTSD in a Veterans Affairs medical center. Married and partnered women veterans, and women veterans who identified as gay/lesbian, were more likely to be open to FM involvement. Results revealed a range of preferences and goals regarding FM involvement. Women veterans expressed a preference for joint sessions at the midpoint or near the end of treatment. Veterans' goals for FM involvement included enhancing the relationship with their FM and providing the FM with a basic understanding of PTSD. Conclusions, limitations, and future directions are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Family accommodation in PTSD: Proposed considerations and distinctions from the established transdiagnostic literature.

Accommodation is widely documented and studied among internalizing disorders; however, the conceptualization and study of accommodation in the context of posttraumatic stress disorder (PTSD) is relatively nascent. PTSD entails many diagnostic criteria-including exposure to a distinct Criterion A event, emotional numbing, and anger-that may uniquely influence accommodation and merit special consideration. Our aim was to review the impact of accommodation in PTSD, compare and contrast accommodation in PTSD to other disorders with a strong empirical evidence base regarding accommodation, and highlight considerations unique to PTSD and associated implications for accommodation. We conclude by providing considerations for future research and practice.

Treatment length and symptom improvement in prolonged exposure and present-centered therapy for posttraumatic stress disorder: Comparing dose-response and good-enough level models in two manualized interventions.

OBJECTIVE: The dose-response model of change in psychotherapy posits that each session of therapy is incrementally beneficial across patients. The contrasting good-enough level model suggests that patients improve at different rates in therapy and discontinue treatment when they are satisfied with their improvement. Support for each theory has been mixed, and many prior studies have relied on samples of patients receiving unstructured treatment approaches. We conducted this study to compare these two theories across two manualized treatments for posttraumatic stress disorder (PTSD). METHOD: Two hundred eighty-four female veterans and military service members with PTSD (Mage = 44.79; 54.6% White non-Hispanic, 6.7% Black non-Hispanic, 37% other) were randomized to receive 10 sessions of prolonged exposure (PE), a trauma-focused therapy, or present-centered therapy (PCT), a non-trauma-focused therapy. Participants completed the PTSD Checklist (PCL) at even-numbered treatment sessions, and the timing of dropout/treatment completion was monitored. RESULTS: The point of highest risk for dropout differed between the treatments, with risk in PE corresponding to the beginning of imaginal exposures. In the PE condition, but not in PCT, a higher number of sessions completed increased the likelihood of achieving reliable clinically significant improvement. Across treatments, the rate of change in PTSD symptoms did not differ according to the number of sessions completed (b = 0.06, p = .687). CONCLUSIONS: Findings support the dose-response model of change in psychotherapy. There were notable differences in dropout across the treatment conditions, including rates, timing, and implications for outcomes. These differences likely reflect differences in content between the protocols. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Mental health therapy for veterans with PTSD as a family affair: A qualitative inquiry into how family support and social norms influence veteran engagement in care.

Social support is important for posttraumatic stress disorder (PTSD) recovery and emerging literature indicate that social support could increase engagement in PTSD therapy. However, there is a need to understand how and why family involvement can increase treatment engagement to inform strategies used in clinical practice. This study explores how individuals with PTSD and family members of individuals with PTSD experience therapy and how social interactions help or hinder therapy engagement. We interviewed 18 U.S. military veterans who had been referred for psychotherapy for PTSD in the Veterans Health Administration and 13 family members and used rapid content analysis to identify themes. We found that engaging in therapy was a family-level decision that participants expected to improve family life. Veterans were motivated to seek treatment to protect their relationships with loved ones. Family members generally encouraged veterans to seek treatment. Specifically, family members who viewed PTSD as a treatable illness versus a static aspect of the veteran's personality expressed positive attitudes about the effectiveness of therapy for reducing symptoms. Veterans whose social networks included individuals with prior military or trauma-related experiences reported that their loved ones possessed more understanding of PTSD and described positive subjective norms around therapy. Family members are often embedded in the therapy process because PTSD has a profound impact on the family. Positive subjective norms for therapy are created by family encouragement and may influence veteran perceptions about the value of treatment. Family members should be engaged early in mental health therapy and to the extent desired by the patient and family member. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Veteran and romantic partner goals for family involvement in PTSD treatment: A qualitative study of dyads.

As part of a larger study of a family-inclusive intervention for veterans beginning treatment for posttraumatic stress disorder (PTSD), we conducted individual semi-structured qualitative interviews with 20 veteran-romantic partner dyads. Topics included previous experiences with partner involvement in health care, goals for this episode of partner involvement, and any concerns about a partner-inclusive approach, as well both participants' understanding of the extent of the partner's knowledge of PTSD and of the veteran's traumatic experiences. Researchers analyzed interview data using a rapid analytic approach, identifying several common emerging themes across participants, as well as some notable but less common perspectives. Participants described a range of hopes and limited concerns regarding integration of the partner into the treatment program; areas of incongruity within dyads also emerged. Overall, veterans and their partners appear to be quite interested in family-inclusive interventions for PTSD and identified goals are largely psychoeducational and supportive in nature.

Psychometric properties of the Posttraumatic Avoidance Behaviour Questionnaire among a treatment-seeking adult sample.

OBJECTIVE: Avoidance of trauma-related stimuli is thought to be central in the development and maintenance of posttraumatic stress disorder (PTSD). However, knowledge of trauma-related avoidance has been limited by conceptualization of this construct as unifactorial and consisting of only two components. The Posttraumatic Avoidance Behaviour Questionnaire (PABQ; van Minnen & Hagenaars, 2010) was developed to assess distinct domains of avoidance. METHOD: The current study expanded upon one prior psychometric study of the PABQ by examining the internal consistency and construct validity of the PABQ among a sample of 177 treatment-seeking adults diagnosed with PTSD. RESULTS: Results indicated that the psychometric properties vary by PABQ subscale. Although all subscales demonstrated adequate internal consistency, items that appear to be negatively impacting internal consistency were identified for several subscales. Although correlations between PABQ subscales indicate subscales index distinct dimensions of trauma-related avoidance, observed similar associations with external correlates suggest these subscales may not functionally differ in their association with PTSD symptoms and co-occurring psychopathology. Accordingly, results suggest further construct validity evidence is needed to determine whether, despite potentially representing distinct domains of avoidance, avoidance of different forms of trauma-related stimuli predicts functionally distinct outcomes. CONCLUSIONS: Collectively, our results indicate that the PABQ is a potentially promising measure for assessing trauma-related avoidance behavior, although additional research is needed to better understand the degree to which these hypothesized distinct domains of avoidance behaviors represent meaningfully distinct constructs.

Concordance in PTSD symptom change between DSM-5 versions of the Clinician-Administered PTSD Scale (CAPS-5) and PTSD Checklist (PCL-5).

The Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) versions of the Clinician-Administered PTSD Scale (CAPS-5) and PTSD Checklist (PCL-5) are widely used PTSD measures. Researchers and clinicians routinely use both measures in tandem to quantify symptom change, despite substantive instrumentation differences beyond administration modality, and absent a theoretical rationale or differential hypotheses for the two measures. The degree to which these measures provide comparable estimates of symptom change is unknown. This study examined concordance in change between CAPS-5 and PCL-5 scores over time. Participants were male veterans (N = 198) randomly assigned to one of two group PTSD treatments. We administered both the CAPS-5 and PCL-5 at baseline, midtreatment, immediately posttreatment, and 3-, 6-, and 12-month posttreatment. Results indicated that CAPS-5 and PCL-5 scores changed over time in a similar manner, as evidenced by generally parallel repeated-measures effect sizes, highly correlated slopes of change (r = .878), and similar associations with improvements in measures of depression and psychosocial functioning. However, the two measures did not produce identical estimates of symptom change. Estimates of symptom improvement were somewhat less concordant at posttreatment follow-up assessments; by the 12-month posttreatment assessment, changes in CAPS-5 scores from baseline indicated somewhat greater symptom improvement than changes in PCL-5 scores (CAPS-5 ESsg = -0.67, PCL-5 ESsg = -0.53). Collectively, results indicate that CAPS-5 and PCL-5 scores produce similar but not identical estimates of PTSD symptom change. Thus, although PCL-5 scores closely approximate symptom change estimated by CAPS-5 scores, the two measures are not interchangeable. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
