RESUMO

OBJECTIVE: To investigate clinicians' perceptions regarding the use of mobile technology tools during prolonged exposure (PE) therapy to allow for monitoring and enhancing in-vivo exposures (IVEs). METHODS: Clinicians with training in PE therapy (N = 32; average of 9 years of practice) completed surveys asking about their perspectives on the utility of virtually attending IVEs with patients while simultaneously having access to real-time subjective and physiological data (i.e., heart rate, galvanic skin conductance) to guide exposure exercises and assure optimal stimulus engagement. RESULTS: Findings showed clinicians to have a favorable view of applying technology devices and systems to enhance IVEs of PE therapy. Most clinicians (93.8%) believed that real-time monitoring of IVEs-particularly monitoring patients' subjective distress and completion of and duration of time in the IVE-would be useful and significantly enhance PE therapy. CONCLUSION: The positive perceptions toward integrating technology into IVEs in this study have important implications for the development and implementation of technology-enhanced PE therapy. A mobile technology system that incorporates real-time indicators of engagement (i.e., both subjective and physiological) during IVEs and allows clinicians to review recordings of, or virtually accompany, patients during IVEs has the potential to innovate and transform PE and other exposure-based treatments. Clinicians also believed that technology-enhanced IVEs may help reduce early termination from PE.

RESUMO

OBJECTIVE: Concurrent Treatment of Posttraumatic Stress Disorder (PTSD) and Substance Use Disorders Using Prolonged Exposure (i.e., COPE) is an efficacious, integrated, psychotherapy that attends to PTSD and substance use disorders simultaneously. No study has examined how therapeutic alliance functions during the provision of COPE and how this compares to non-integrated treatments, such as relapse prevention (RP) for substance use disorders. Understanding the role of alliance in COPE versus RP could inform treatment refinement and ways to enhance treatment outcomes. METHODS: Participants (N = 55 veterans) were randomized to 12, individual, weekly sessions of COPE or RP in a randomized clinical trial. Piecewise linear mixed effect models examined how mid-treatment (1) patient-rated alliance, (2) therapist-rated alliance, and (3) the convergence between patient- and therapist-rated alliance as measured by a difference score predicted reductions in PTSD symptoms and substance use across treatment and follow-up periods. RESULTS: Both patient- and therapist-rated alliance predicted reductions in PTSD symptoms in COPE. Higher patient-rated alliance predicted lower percent days using substances in RP. Difference score models showed higher patient-rated alliance relative to therapist-rated alliance scores predicted symptom reductions in COPE whereas higher therapist-rated alliance scores relative to patient-rated alliance scores predicted symptom reductions in RP. DISCUSSION: Preliminary findings show a unique relationship between the rater of the alliance and treatment modalities. Patient-rated alliance may be important in trauma-focused, integrated treatments whereas therapist-rated alliance may be more important in skills-focused, substance use interventions.

RESUMO

Multiple factor analytic and item response theory studies have shown that items/symptoms vary in their relative clinical weights in structured interview measures for posttraumatic stress disorder (PTSD). Despite these findings, the use of total scores, which treat symptoms as though they are equally weighted, predominates in practice, with the consequence of undermining the precision of clinical decision-making. We conducted an integrative data analysis (IDA) study to harmonize PTSD structured interview data (i.e., recoding of items to a common symptom metric) from 25 studies (total N = 2,568). We aimed to identify (a) measurement noninvariance/differential item functioning (MNI/DIF) across multiple populations, psychiatric comorbidities, and interview measures simultaneously and (b) differences in inferences regarding underlying PTSD severity between scale scores estimated using moderated nonlinear factor analysis (MNLFA) and a total score analog model (TSA). Several predictors of MNI/DIF impacted effect size differences in underlying severity across scale scoring methods. Notably, we observed MNI/DIF substantial enough to bias inferences on underlying PTSD severity for two groups: African Americans and incarcerated women. The findings highlight two issues raised elsewhere in the PTSD psychometrics literature: (a) bias in characterizing underlying PTSD severity and individual-level treatment outcomes when the psychometric model underlying total scores fails to fit the data and (b) higher latent severity scores, on average, when using DSM-5 (net of MNI/DIF) criteria, by which multiple factors (e.g., Criterion A discordance across DSM editions, changes to the number/type of symptom clusters, changes to the symptoms themselves) may have impacted severity scoring for some patients.

RESUMO

The debate around the construct validity of complex posttraumatic stress disorder (CPTSD) has begun to examine whether CPTSD diverges from posttraumatic stress disorder (PTSD) when it co-occurs with the diagnosis of borderline personality disorder (BPD). The present study (a) examined the construct validity of CPTSD through a latent class analysis of a non-treatment-seeking sample of young trauma-exposed adults and (b) characterized each class in terms of trauma characteristics, social emotions (e.g., shame, guilt, blame), and interpersonal functioning. A total of 23 dichotomized survey items were chosen to represent the symptoms of PTSD, CPTSD, and BPD and administered to 197 trauma-exposed participants. Fit statistics compared models with 2-4 latent classes. The four-class model showed the best fit statistics and clinical interpretability. Classes included a "high PTSD+CPTSD+BPD" class, characterized by high-level endorsement of all symptoms for the three diagnoses; a "moderate PTSD+CPTSD+BPD" class, characterized by endorsement of some symptoms across all three diagnoses; a "PTSD" class, characterized by endorsement of the ICD-11 PTSD criteria; and a "healthy" class, characterized by low symptom endorsement overall. Pairwise comparisons showed individuals in the high PTSD+CPTSD+BPD class to have the highest levels of psychological distress, traumatic event history, adverse childhood experiences, and PTSD symptoms. Shame was the only social emotion to significantly differ between the classes, p = .002, η² = .16. The findings diverge from the literature, indicating an overlap of PTSD, CPTSD, and BPD symptoms in a non-treatment-seeking community sample. Further, shame may be a central emotion that differentiates between presentation severities following trauma exposure.

RESUMO

Identifying clinical differences between opioid users (OU) and alcohol and other drug users (AOD) may help to tailor treatment to OU, particularly among the majority of OU who are not on opioid agonist treatments. Given the dearth of research on these differences, this study explored gender differences in demographic and clinical characteristics between OU and AOD. Participants (N = 506) were from a multisite, randomized controlled clinical trial of an Internet-delivered psychosocial intervention conducted in 2010-2011. Logistic regression models explored differences in demographic and clinical characteristics by substance use category within and between women and men. Women OU were more likely to be younger, White, employed, benzodiazepine users, and less likely to have children or use cocaine and cannabis than women AOD. Men OU, compared to men AOD, were more likely to be younger, White, younger at first abuse/dependence, benzodiazepine users, and reported greater psychological distress, but were less likely to be involved in criminal justice or use stimulants. Interactions by gender and substance use were also detected for age of first abuse/dependence, employment, and criminal justice involvement. These findings provide a nuanced understanding of gender differences within substance use groups to inform providers for OU seeking treatment.

RESUMO

Posttraumatic stress disorder (PTSD) is a complex condition with affective components that extend beyond fear and anxiety. The emotion of shame has long been considered critical in the relation between trauma exposure and PTSD symptoms. Yet, to date, no meta-analytic synthesis of the empirical association between shame and PTSD has been conducted. To address this gap, the current study summarized the magnitude of the association between shame and PTSD symptoms after trauma exposure. A systematic literature search yielded 624 publications, which were screened for inclusion criteria (individuals exposed to a Criterion A trauma, and PTSD and shame assessed using validated measures of each construct). In total, 25 studies employing 3,663 participants met full eligibility criteria. A random-effects meta-analysis revealed a significant moderate association between shame and posttraumatic stress symptoms, r = .49, 95% CI [0.43, 0.55], p < .001. Moderator analyses were not completed due to the absence of between-study heterogeneity. Publication bias analyses revealed minimal bias, determined by small attenuation after the superimposition of weight functions. The results underscore that across a diverse set of populations, shame is characteristic for many individuals with PTSD and that it warrants a central role in understanding the affective structure of PTSD. Highlighting shame as an important clinical target may help improve the efficacy of established treatments. Future research examining shame's interaction with other negative emotions and PTSD symptomology is recommended.


Spanish Abstracts by Asociación Chilena de Estrés Traumático (ACET) Asociación entre la vergüenza y el trastorno por estrés postraumático: un metaanálisis METANALISIS DE LA VERGÜENZA Y EL ESTRÉS POSTTRAUMATICO El trastorno por estrés postraumático (TEPT) es una condición compleja con componentes afectivos que se extienden más allá del miedo y la ansiedad. La emoción de vergüenza ha sido ampliamente considerada como crítica en la relación entre la exposición al trauma y los síntomas de TEPT. Sin embargo, hasta la fecha, no se ha desarrollado una síntesis meta-analítica de la asociación empírica entre vergüenza y TEPT. Para abordar esta brecha, este estudio resumió la magnitud de la asociación entre la vergüenza y los síntomas del TEPT, después de la exposición al trauma. Una búsqueda sistemática de la literatura arrojó 618 publicaciones, que fueron seleccionados según los criterios de inclusión (individuos expuestos a un trauma del Criterio A, y que utilizaron medidas validadas para evaluar cada uno de estos constructos, TEPT y vergüenza). En total, 25 estudios que emplearon 3.663 participantes cumplieron con todos los criterios de elegibilidad. Un metanálisis de efectos aleatorios reveló una asociación moderada significativa entre la vergüenza y los síntomas de TEPT, r = .49, IC 95% [0.43, 0.55], p <.001. No se finalizaron los análisis de moderación debido a la ausencia de heterogeneidad entre los estudios. El análisis de sesgo de publicación reveló un sesgo mínimo, determinado por una pequeña atenuación después de la superposición de funciones ponderadas. Los resultados subrayan que, a través de un conjunto diverso de poblaciones, la vergüenza es característica para muchas personas con TEPT y que ocupa un rol central en la comprensión de la estructura afectiva del TEPT. La vergüenza destaca como un objetivo clínico de relevancia que puede ayudar a mejorar la eficacia de los tratamientos existentes. Se recomienda a la investigación futura que examine la interacción de la vergüenza con otras emociones negativas y la sintomatología del TEPT.

RESUMO

BACKGROUND & OBJECTIVES: We investigated gender differences in individuals with opioid use disorder (OUD) receiving inpatient services and entering a randomized controlled trial comparing extended-release naltrexone to buprenorphine. METHODS: Participants (N = 570) provided demographic, substance use, and psychiatric information. RESULTS: Women were significantly younger, more likely to identify as bisexual, live with a sexual partner, be financially dependent, and less likely employed. Women reported significantly greater psychiatric comorbidity and risk behaviors, shorter duration but similar age of onset of opioid use. DISCUSSION/CONCLUSIONS: Findings underscore economic, psychiatric, and infection vulnerability among women with OUD. SCIENTIFIC SIGNIFICANCE: Interventions targeting these disparities should be explored, as women may face complicated treatment initiation, retention, and recovery. (Am J Addict 2018;27:465-470).

RESUMO

Introduction: Substance use is strongly associated with intimate partner violence (IPV) and is a modifiable risk factor for IPV. However, lack of comprehensive screening and referral for co-occurring IPV and substance use, along with their psychiatric sequalae, limits the identification and implementation of effective interventions for substance-related IPV. This narrative review (1) investigates the literature on screening and referral practices for IPV, and if these include screening for substance use or other psychiatric comorbidities, (2) provides recommendations for current best practices, and (3) suggests future directions for research and practice aimed at identifying and reducing substance-related IPV. Methods: A narrative literature review examined studies investigating IPV screening and referral programs in clinics. Selected studies were reviewed for: (1) effectiveness, (2) barriers to implementation and sustainability, and (3) responsivity to psychiatric comorbidity, including substance use and substance use disorders (SUD). Results: Findings suggest that effective IPV screening and referral programs have been developed, but disparities in IPV screening exist and many programs only screen for IPV victimization. Barriers to the implementation and sustainability of IPV screening programs include lack of ongoing provider training, funding or institutional support, and direct connection to referral services. Further, many IPV screening programs lack assessment of and referral for comorbid psychiatric conditions, including substance use, and tend not to be routinely implemented in SUD clinics. Discussion: Additional systematic work is needed to develop universal and comprehensive screening and referral programs for substance-related IPV and address issues of long-term sustainability, particularly within SUD treatment settings.

RESUMO

OBJECTIVES: The legacy of slavery renders Black individuals vulnerable to the harmful effects of historical trauma which may interact with contemporary racism-related experiences to increase substance use. We examined the associations between historical and contemporary racism-related experiences (i.e., historical loss thinking, major racial discrimination events, racial microaggressions, and internalized racism) and polysubstance use in a group of Black young adults. METHOD: Black young adults (N = 163; 60% female) aged 18-35 years (M = 25.7, SD = 3.27) completed surveys online. RESULTS: Historical loss thinking (b = 0.03, 95% CI [0.01, 0.05], p = .003), racial microaggressions (b = 0.03, 95% CI [0.02, 0.04], p < .001), major racial discrimination events (b = 0.42, 95% CI [0.30, 0.53], p < .001), and internalized racism (b = 0.49, 95% CI [0.33, 0.65], p < .001) were independently associated with past 12-month polysubstance use. Major racial discrimination events showed the largest association with polysubstance use (ß = 0.26, 95% CI [0.08, 0.45], p = .006). No significant interactions between historical loss thinking and contemporary racism-related experiences were observed. CONCLUSIONS: Findings suggest an association between substance use and historical and contemporary-related experiences among Black young adults. This may suggest that experiences with racism contextualized within historical and contemporary manifestations may impact risk for polysubstance use among Black young adults.

RESUMO

Non-medical prescription opioid use (NMPOU) is the use of opioids without a prescription or in a way different from how they were prescribed and is the fourth most common type of drug use in the United States. Separate research has shown that trauma-related shame is linked to posttraumatic stress disorder (PTSD) and, respectively, opioid use. However, no study to date has empirically examined the association between trauma-related shame and NMPOU among individuals with PTSD symptoms. Forty adults with clinical or subclinical PTSD who reported engaging in NMPOU at least one day in the prior month before the study completed 28 days of daily surveys. Trauma-related shame was measured at baseline. NMPOU and underlying motives to engage in NMPOU were assessed once daily via a smartphone app. Twenty-four participants (60 %) reported NMPOU over the 28-day period. After controlling for PTSD symptoms and covariates, mixed models showed that higher trauma-related shame significantly predicted higher risk of daily NMPOU (B = 0.06, SE = 0.03, t = 2.14, p=.03). After controlling for false discovery rates, trauma-related shame also significantly predicted NMPOU due to the following motives (p's < 0.031): to manage depression/sadness, to manage anxiety, to manage other stress/worry, and to get high. Among individuals with PTSD, higher baseline trauma-related shame prospectively and positively predicted greater NMPOU over a four-week daily monitoring period. Findings suggest a need to attend to trauma-related shame and its impact on subsequent motivations to engage in NMPOU. Future research should examine how treatments may effectively target trauma-related shame to reduce NMPOU and more severe PTSD symptoms.

RESUMO

INTRODUCTION: Women show a gender-specific risk for co-occurring opioid use disorder (OUD) and posttraumatic stress disorder (PTSD). Expert groups have called for the development of integrated treatments for women with OUD/PTSD, but there remains limited information on such interventions. METHODS: This mixed-methods study interviewed and surveyed 10 women with current or past OUD and co-occurring posttraumatic stress symptoms (PTSS) and 16 providers who work with these women. Interviews and surveys queried patient participants' and providers' experiences of OUD/PTSS and how to best design an integrated, trauma-focused treatment for OUD/PTSD. RESULTS: Patient participants (90 % white, 90 % mothers, Mage = 45.70) met criteria for severe, lifetime OUD and 40 % met a provisional diagnosis for PTSD. Four themes emerged for participants' experiences of OUD/PTSS: 1) numerous stressors; 2) shame; 3) multiple motivations to use opioids; and 4) a cycle of trauma and opioid use. Four themes emerged regarding patient participants' perceptions on the development of an OUD/PTSD treatment: 1) mixed attitudes towards medications for OUD; 2) barriers to treatment (e.g., insufficient treatments and contextual factors); 3) treatment facilitators (e.g., social support); and 4) preferences in treatment (e.g., trauma-focused, gender-focused, family content, ambivalence around group therapy). Providers (Mage = 38.94) were primarily white women (76.5 %). Two themes emerged from their experiences working with women with OUD/PTSS: 1) perceiving women to use opioids to regulate emotions and 2) gender differences in trauma types. Three themes emerged for providers' perceptions on the development of an OUD/PTSD treatment: 1) barriers to treatment (e.g., chaotic lives, contextual factors, family); 2) treatment facilitators (e.g., trust and external motivations); and 3) desired treatment modifications (e.g., stabilization, early skills in therapy, flexibility in therapy, social supports, safety guidelines, and assistance in identifying an index trauma). Most participants (90.0 %) and providers (93.5 %) preferred working on OUD/PTSD symptoms simultaneously rather than separately. CONCLUSIONS: Findings demonstrate the need to modify integrated treatments to meet the preferences of providers and women with OUD/PTSS and OUD/PTSD. Treatments should consider therapeutic content, structure, contextual factors, social support, and PTSD severity to enhance uptake and reach.

RESUMO

High rates of cannabis use among people with posttraumatic stress disorder (PTSD) have raised questions about the efficacy of evidence-based PTSD treatments for individuals reporting cannabis use, particularly those with co-occurring alcohol or other substance use disorders (SUDs). Using a subset of four randomized clinical trials (RCTs) included in Project Harmony, an individual patient meta-analysis of 36 RCTs (total N = 4046) of treatments for co-occurring PTSD+SUD, we examined differences in trauma-focused (TF) and non-trauma-focused (non-TF) treatment outcomes for individuals who did and did not endorse baseline cannabis use (N = 410; 70% male; 33.2% endorsed cannabis use). Propensity score-weighted mixed effects modeling evaluated main and interactive effects of treatment assignment (TF versus non-TF) and baseline cannabis use (yes/no) on attendance rates and within-treatment changes in PTSD, alcohol, and non-cannabis drug use severity. Results revealed significant improvements across outcomes among participants in all conditions, with larger PTSD symptom reductions but lower attendance among individuals receiving TF versus non-TF treatment in both cannabis groups. Participants achieved similar reductions in alcohol and drug use across all conditions. TF outperformed non-TF treatments regardless of recent cannabis use, underscoring the importance of reducing barriers to accessing TF treatments for individuals reporting cannabis use.

RESUMO

The current study examined frontal alpha asymmetry (FAA) as a marker of approach- and avoidance-related prefrontal activity in participants with and without trauma exposure and posttraumatic stress disorder (PTSD). We investigated FAA in an inhibitory control paradigm (threatening vs nonthreatening cues) under 2 levels of cognitive demand (baseline: images constant within a block of trials; vs filtering: images varied randomly within a block) in 3 groups of participants: individuals with PTSD (n = 16), exposed to trauma but without PTSD (n = 14), and a control group without PTSD or trauma exposure (n = 15). Under low demand (baseline), both PTSD and trauma-exposed participants exhibited significantly greater relative left than right frontal brain activity (approach) to threatening than to nonthreatening images. Under high demand (filtering), no FAA differences were found between threatening and nonthreatening images, but PTSD participants revealed more relative left than right FAA, whereas trauma-exposed participants showed reduced left relative right FAA. In all conditions, healthy controls exhibited reduced left relative to right FAA and no differences between threatening and nonthreatening images. Study findings suggest dysfunctional prefrontal mechanisms of emotion regulation in PTSD, but adaptive prefrontal regulation in trauma-exposed individuals without PTSD.

RESUMO

OBJECTIVE: PTSD and substance use disorders (SUD) frequently co-occur among veterans. Integrated exposure-based treatments, such as Concurrent Treatment of PTSD and SUD Using Prolonged Exposure (COPE), are efficacious in reducing PTSD and SUD symptoms and posttraumatic emotions. This study examines whether guilt and anger (a) decreased in a randomized clinical trial comparing COPE with Relapse Prevention (RP) therapy for SUD and (b) mediated PTSD and SUD symptom reductions or vice versa. METHOD: Veterans (90.1% men) diagnosed with PTSD and SUD were randomized to 12 sessions of COPE (n = 54) or RP (n = 27). Guilt and anger were assessed at 10 time points during treatment. Multilevel linear models assessed changes in guilt and anger across treatments and lagged multilevel mediation analyses assessed within-subject change in guilt and anger predicting PTSD and percent days of substance use, and vice versa. RESULTS: Guilt (B = -.12, SE = .02, p < .001) and anger (B = -.13, SE = .02, p < .001) improved in both treatments, however guilt was significantly lower in Sessions 7 through 11 among veterans receiving COPE. Improvement in guilt mediated PTSD symptom improvement in both treatment groups (B = -.08, SE = .04, 95% CI [-.16, -.01]), and PTSD symptom improvement mediated anger reduction in COPE (B = -.03, SE = .01, 95% CI [-.06, -.01]). The substance use models were insignificant. CONCLUSIONS: Among veterans, integrated, trauma-focused treatments may be associated with greater guilt (directly) and anger (indirectly) reductions due to processing trauma.

RESUMO

Purpose of Review: Research demonstrates a strong association between alcohol use disorder (AUD) and posttraumatic stress disorder (PTSD). However, less is known about sex- and gender-based differences among individuals with AUD + PTSD. This narrative review examines recent literature in this area and aims to be a reference for future research endeavors. Recent Findings: Extant literature shows that intertwining biological systems increase females' risk of developing PTSD and experiencing more adverse effects from AUD compared to males. Sex-based physiological differences further interact with gendered sociocultural environments to influence the risk of AUD + PTSD. Emerging research suggests potential gender-specific pathways between PTSD, coping, and AUD which may inform prevention and treatment. However, barriers to care are often gender-specific and tailored approaches are needed to improve reach and uptake. Summary: Additional research is needed to examine intersectional and contextual factors that synergistically influence sex/gender differences in AUD + PTSD, particularly beyond cisgender identities, and mechanisms of action.

RESUMO

BACKGROUND: A significant proportion of individuals with alcohol use disorder (AUD) also meet criteria for posttraumatic stress disorder (PTSD). Military veterans are at increased risk for developing co-occurring AUD/PTSD, with prevalence rates 2-4 times higher than the general population. Research is needed to develop more effective treatments for this common comorbidity. The current investigation addresses this need by examining the synergistic effects of a novel pharmacotherapy combined with psychotherapy for co-occurring AUD/PTSD among veterans. Accumulating evidence suggests that the neuropeptide oxytocin (OT) is a promising pharmacotherapy to augment psychotherapy for AUD/PTSD. OT targets neurobiological and behavioral dysregulation common to both AUD and PTSD, in particular, corticolimbic connectivity. Human and animal studies show OT reduces alcohol self-administration, tolerance, and withdrawal; enhances fear extinction; and promotes prosocial behaviors. The current study builds on previous work by examining OT among veterans with AUD/PTSD receiving Concurrent Treatment of PTSD and Substance Use Disorders using Prolonged Exposure (COPE), an evidence-based integrated treatment. METHODS: This paper describes the rationale, design, and methodology of a Stage II, 12-week, double-blind, randomized clinical trial of intranasal OT (40 IU) versus placebo combined with COPE among veterans (N = 180) with current AUD/PTSD. In addition, the effects of treatment on corticolimbic connectivity will be examined using functional magnetic resonance imaging (fMRI) at pre- and post-treatment. CONCLUSIONS: The proposed study will provide new knowledge and mechanistic insights to accelerate research in this understudied area and may lead to improved treatment outcomes for co-occurring AUD/PTSD.

RESUMO

Objective: Social support may be a critical mechanism in the treatment of co-occurring substance use disorder (SUD) and posttraumatic stress disorder (PTSD). However, no studies have examined how social support changes as a function of treatment or predicts treatment outcome in a Veteran population with co-occurring SUD and PTSD. Method: The current study is a secondary analysis that examined social support over the course of treatment for co-occurring SUD and PTSD (N = 81). Analyses were conducted to examine if a) social support predicts change in substance use and PTSD symptoms, respectively, over the course of treatment and during follow-up, and b) substance use and PTSD symptoms, respectively, predicts change in social support over treatment and during follow-up. Results: The findings revealed that between-person social support moderated decreases in substance use (B = -0.17, SE = 0.07, p = 0.017) and PTSD symptom severity (B = -0.12, SE = 0.05, p = 0.009) during treatment but not during follow-up. Within-person substance use and PTSD symptom severity predicted social support but substance use and PTSD symptoms did not moderate changes in social support during treatment or follow-up. Conclusions: The findings highlight the critical role of social support during treatment in enhancing outcomes for individuals with co-occurring SUD and PTSD.

RESUMO

INTRODUCTION: Black women are at heightened risk for trauma exposure, post-traumatic stress disorder (PTSD), and substance use disorders (SUDs), compared to White women and the general population. However, disparities in treatment engagement and retention persist, particularly for Black women with co-occurring PTSD+SUD. Although therapeutic alliance is an important predictor and mediator of treatment retention and outcomes, we know little about predictors of alliance and the mediating role of alliance for PTSD+SUD outcomes among Black women. METHODS: This study utilized data previously collected for the National Drug Abuse Treatment Clinical Trials Network (CTN) Women and Trauma Study. Participants were 88 Black/African American women (Mage = 41.90, SD = 7.72) participating in a clinical trial comparing Seeking Safety (a cognitive-behavioral intervention for PTSD+SUD) to Women's Health Education (control). This study includes participants from both arms. Measures included the Helping Alliance Questionnaire, Addiction Severity Index-Lite, and Clinician Administered PTSD Scale. Women in the intervention arm also completed the Seeking Safety Feedback Questionnaire. RESULTS: Stepwise, hierarchical linear regressions indicated that years of education and previous alcohol/drug treatment attempts significantly predicted early alliance in the second week of therapy (ß = 0.411, p = .021 and ß = 0.383, p = .011, respectively), but not late alliance in the last week of therapy (ps > .794). Greater education and more treatment attempts were associated with higher early alliance. Alliance did not mediate relationships between these significant predictors and treatment outcomes (e.g., attendance, post-treatment PTSD and SUD symptoms) or treatment feedback in the Seeking Safety group. CONCLUSIONS: Education and prior treatment attempts predicted early alliance among Black/African American women in PTSD+SUD group treatment, and higher education level was associated with poorer Seeking Safety feedback topic ratings. Educational level and treatment history should be considered during alliance building in therapeutic interventions with Black women. Clinicians may consider the integration of pre-treatment alliance-building strategies with Black female patients who have lower levels of education. This study provides insight into the relative impact of several important factors that influence early alliance among Black women with co-occurring PTSD+SUD.

RESUMO

Objective: The co-occurrence of substance use disorders (SUD) and trauma-exposure is a risk factor for suicidal thoughts and behaviors (STB). However, traditional methods of measurement for suicidal thoughts and behaviors are limited by an overreliance on dichotomous (i.e., yes or no) and averaged/summed scale score measurements. Further, among trauma-exposed individuals with SUD, it remains unclear which specific demographic factors, types of SUDs, and trauma sequelae (e.g., posttraumatic stress disorder [PTSD] symptom clusters) may be associated with elevated STB. The present study utilized item response theory to (a) generate empirically derived STB severity scores and, (b) examine which demographic factors, SUD diagnoses, and DSM-IV PTSD symptom clusters are associated with suicidality in a trauma-exposed sample with SUDs. Method: Female trauma-exposed participants with SUDs (N = 544) were recruited from community substance use treatment facilities in the National Drug Abuse Treatment Clinical Trials Network (CTN). Clinician-administered interviews assessed STB, SUDs, and PTSD symptoms. Results: Results indicated that the unidimensional item response theory (IRT) model used to estimate latent STB severity scores fit well, with strong local reliability at higher levels of latent STB severity. Regression predictors of elevated STB severity included younger age, opioid dependence, and higher PTSD reexperiencing symptoms. Conclusions: Clinicians are advised to screen for and target opioid use disorders and reexperiencing symptoms when addressing suicidal thoughts and behavior in trauma-exposed individuals with SUDs.

RESUMO

Prolonged Exposure (PE) therapy is one of the most efficacious, evidence-based treatments for posttraumatic stress disorder (PTSD). A key component of PE involves in vivo exposures (IVEs) during which patients approach situations or activities in "real life" that are safe but avoided because they elicit a fear response. Despite their critical role in treatment, little research has focused on IVEs. This gap in knowledge is primarily due to the fact that IVEs are typically conducted by patients in between therapy sessions, leaving clinicians reliant upon patient self-report. This approach has numerous shortcomings, which the current study addresses by leveraging technology to develop an innovative device that allows for physiological, biomarker-driven, therapist-guided IVEs. The new system enables clinicians to virtually accompany patients during IVEs and provides real-time physiological (heart rate, skin conductance) and self-report (subjective units of distress) data that clinicians can use to modify the exposure and optimize therapeutic value. This Small Business Innovation Research (SBIR) Phase I project aims to: (1) integrate physiological sensors and live audio/visual streaming into a system for clinicians to guide patients during IVEs; (2) determine feasibility and acceptability of the system; and (3) conduct a pilot randomized clinical trial among veterans with PTSD (N = 40) to evaluate the preliminary efficacy of the system in reducing PTSD symptoms during PE. This paper describes the rationale, design, and methodology of the Phase I project. The findings from this study have the potential to innovate clinical practice, advance the science of exposure therapy, and improve clinical outcomes.
