Expanding the Reach of Effective PTSD Treatment Into Primary Care: Prolonged Exposure for Primary Care

Clinical Education: Addressing Prior Trauma and Its Impacts in Medical Settings

Prior trauma exposure significantly increases the risk of developing PTSD following medical stressors and may contribute to the development of medically induced PTSD. However, healthcare systems often overlook the interaction between prior trauma and current medical stressors, contributing to negative psychosocial and health-related outcomes for patients. Integration of both trauma-informed and trauma-focused practices into psychosocial programming in medical settings may be key to effectively addressing the needs of trauma-exposed patients. Yet, there is a lack of practical guidance on how clinical psychologists in medical settings can respond to trauma's effects in routine clinical practice. This paper aims to provide an overview of trauma-focused theory, assessment, and treatment considerations within medical settings, emphasizing the importance of incorporating trauma-focused intervention into integrated psychosocial programming to address prior trauma and its impacts on care in order to improve patient outcomes.

State of the Science: Prolonged exposure therapy for the treatment of posttraumatic stress disorder

Prolonged exposure therapy (PE) is a well-established first-line treatment for posttraumatic stress disorder (PTSD) that is based on emotional processing theory. PE has been rigorously evaluated and tested in a large number of clinical trials in many countries covering a wide range of trauma populations. In this review, we summarize the evidence base supporting the efficacy of PE across populations, including adults with sexual assault-related PTSD and mixed trauma-related PTSD, military populations, and adolescents. We highlight important strengths and gaps in the research on PE with individuals from marginalized communities. We discuss the efficacy of PE on associated psychopathology and in the presence of the most commonly comorbid conditions, either alone or integrated with other treatments. In addition, we provide an overview of research examining strategies to augment PE. Much of this work remains preliminary, but numerous trials have tested PE in combination with other psychological or pharmacological approaches, interventions to facilitate extinction learning, and behavioral approaches, in the hopes of further increasing the efficiency and efficacy of PE. There are now several trials testing PE in novel formats that may have advantages over standard in-person PE, such as lower dropout and increased scalability. We examine this recent work on new models of delivering PE, including massed treatment, telehealth, and brief adaptations for primary care, all of which have the potential to increase access to PE. Finally, we highlight several promising areas for future research.

Preliminary Investigation Into the Effectiveness of Group webSTAIR for Trauma-exposed Veterans in Primary Care

INTRODUCTION

A substantial number of trauma-exposed veterans seen in primary care report significant symptoms of PTSD and depression. While primary care mental health integration (PCMHI) providers have been successful in delivering brief mental health treatments in primary care, few studies have evaluated interventions that combine mobile health resources with PCMHI groups. This pilot study assessed the potential benefits of webSTAIR, a 10-module transdiagnostic treatment for trauma-exposed individuals, supported by 5 biweekly group sessions delivered via telehealth. The transdiagnostic and mobile health nature of the treatment, as well as the therapist and peer support provided through group sessions, may offer an innovative approach to increasing access to patient-centered and trauma-informed treatment in primary care settings.

MATERIALS AND METHODS

Thirty-nine male and female veterans with trauma-related symptoms (i.e., PTSD and/or depression) participated in group webSTAIR. Mixed effects analyses were conducted to assess changes in PTSD and depression at pre-, mid-, and post-treatment. Baseline symptom severity was assessed as a predictor of module completion and group attendance. The project was part of a VHA quality improvement project, and IRB approval was waived by the affiliated university.

RESULTS

Analyses revealed significant pre-to-post improvement in both PTSD and depression outcomes with a large effect size for PTSD (Hedges' gav = 0.88) and medium to large for depression (Hedges' gav = 0.73). Of participants who completed the baseline assessment, 90% began webSTAIR; of those, 71% completed the program. Baseline symptoms of PTSD and depression did not predict group attendance or module completion.

CONCLUSIONS

Good outcomes and a satisfactory retention rate suggest that group webSTAIR may provide easily accessible, high-quality, and effective treatment for patients presenting with trauma-related problems without increasing therapist or system burdens. The results suggest the value of conducting a randomized controlled trial to test the effectiveness of group webSTAIR relative to PCMHI usual care or other evidence-based, disorder-specific (e.g., PTSD) treatments for trauma-exposed individuals in PCMHI.

Characteristics of recently incarcerated primary care patients with and without a positive posttraumatic stress disorder screening upon clinic intake

OBJECTIVE

Posttraumatic stress disorder (PTSD) is prevalent among people who have been incarcerated. Here, we examined whether screening positive for PTSD was associated with other indicators of poor health, acute healthcare utilization, and poverty among primary care patients upon release from incarceration.

METHOD

We conducted a cross-sectional survey in a national network of primary care clinics serving people recently released from incarceration. Participants were 416 patients who completed the Primary Care PTSD screen (PC-PTSD) and other questions about mental and physical health, acute healthcare utilization, and economic status within 6 months of release.

RESULTS

Screening positive for PTSD was associated with worse status across nearly all variables examined, including being more likely to report: poor/fair health (61.6% vs. 41.7%), current depressive symptoms (89.7% vs. 50.8%), lifetime depression diagnosis (63.3% vs. 35.3%), cannabis use since release (20.7% vs. 9.6%), homelessness (31.9% vs. 18.5%), having no cash on hand (56.3% vs. 39.0%) and severe food insecurity (29.3% vs. 18.2%; all ps < .01). Reporting recent suicidality (14.3% vs. 7.0%), alcohol use since release (30.2% vs. 20.0%), and emergency department utilization (20.4% vs. 12.2%) was also more likely (all ps ≤ .03). These trends were largely upheld when controlling for demographic characteristics and chronic physical health conditions using linear probability regression.

CONCLUSIONS

Primary care patients recently released from incarceration have a need for wrap-around services that address health challenges and poverty. Patients with significant PTSD symptoms face even greater challenges. Identification and treatment of PTSD both during and after incarceration is warranted.

Characteristics of Veterans With Depression Who Use the Veterans Choice Program of the Veterans Health Administration

OBJECTIVE

The Veterans Choice Program (VCP) of the Veterans Health Administration (VHA) allowed eligible veterans to use their benefits with participating providers outside the VHA. The authors aimed to identify characteristics of veterans with depression who used or did not use mental health care through the VCP.

METHODS

In this cross-sectional study, the authors analyzed secondary data from the national VHA Corporate Data Warehouse. VHA administrative data were linked with VCP claims to examine characteristics of VCP-eligible veterans with depression. The study sample included 595,943 unique veterans who were enrolled in the VHA before 2013, were eligible for the VCP in 2016, were alive in 2018, and had an assessed Patient Health Questionnaire-9 (PHQ-9) score or depressive disorder diagnosis documented in the VHA between 2016 and 2018.

RESULTS

Veterans who used the VCP had lower medical comorbidity scores and lived in less socioeconomically disadvantaged counties, compared with veterans who received only VHA care. VCP veterans were also more likely to have a PHQ-9 score assessment and to have higher mean depression scores. Mean counts of annual mental health visits per 1,000 veterans were markedly higher for direct VHA care than for care provided via the VCP. As a percentage of the total counts of visits per 1,000 veterans across the VCP and VHA, residential programs and outpatient procedures were the services that were most frequently delivered through the VCP.

CONCLUSIONS

Between 2016 and 2018, the VCP was used primarily to augment mental health care provided by the VHA, rather than to fill a gap in care.

Treatment of posttraumatic stress disorder with prolonged exposure for primary care (PE-PC): Effectiveness and patient and therapist factors related to symptom change and retention

Prolonged exposure (PE) is a first-line treatment for posttraumatic stress disorder (PTSD) available in specialty mental health. PE for primary care (PE-PC) is a brief version of PE adapted for primary care mental health integration, composed of four-eight, 30-min sessions. Using retrospective data of PE-PC training cases from 155 Veterans Health Administration (VHA) providers in 99 VHA clinics who participated in a 4- to 6-month PE-PC training and consultation program, we examined patients' PTSD and depression severity across sessions via mixed effects multilevel linear modeling. Additionally, hierarchical logistic regression analysis was conducted to assess predictors of treatment dropout. Among 737 veterans, medium-to-large reductions in PTSD (intent-to-treat, Cohen's d = 0.63; completers, Cohen's d = 0.79) and small-to-medium reductions in depression (intent-to-treat, Cohen's d = 0.40; completers, Cohen's d = 0.51) were observed. The modal number of PE-PC sessions was five (SD = 1.98). Providers previously trained in both PE and cognitive processing therapy (CPT) were more likely than providers who were not trained in either PE or CPT to have veterans complete PE-PC (OR = 1.54). Veterans with military sexual trauma were less likely to complete PE-PC than veterans with combat trauma (OR = 0.42). Asian American and Pacific Islander veterans were more likely than White veterans to complete treatment (OR = 2.93). Older veterans were more likely than younger veterans to complete treatment (OR = 1.11). (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Barriers to and facilitators of using evidence-based, cognitive-behavioral anxiety interventions in integrated primary care practice

Cognitive-behavioral treatment for anxiety disorders and symptoms remains underutilized in integrated primary care (IPC), in part because the many treatments developed for specialty care are not readily translated to this unique setting. The objective of this study was to identify barriers and facilitators to behavioral health providers (BHPs) delivering evidence-based cognitive--behavioral anxiety interventions within IPC practice. We conducted semistructured interviews with a national sample of 18 BHPs (50% psychologists, 33% social workers, 17% registered nurses) working in IPC in the Veterans Health Administration. We assessed barriers to and facilitators of using psychoeducation, exposure, cognitive therapy, relaxation training, mindfulness/meditation, Acceptance and Commitment Therapy-based interventions, and problem-solving therapy. Qualitative coding and conventional content analysis revealed barriers and facilitators at three levels: IPC, provider, and patient. Themes suggested key barriers of poor fit with the IPC model, BHP training deficits, and lack of patient buy-in, and key facilitators of good perceived fit of the intervention (e.g., scope, duration) with the IPC model, BHPs feeling well equipped, and utility for patients. BHPs select interventions based on fit for the individual patient. Some results were consistent with prior work from specialty care, but the IPC model itself introduces significant implementation challenges. BHPs would benefit from flexible intervention options and training on IPC treatment goals and how to deliver the essence of evidence-based interventions in small doses. Our findings will help to inform adaptation of behavioral anxiety interventions to better fit IPC practice and development of beneficial training and resources for BHPs to reduce implementation challenges.

Primary Care Treatment Integrating Motivation and Exposure for PTSD Symptoms and Hazardous Alcohol Use: A Case Series

Symptoms of posttraumatic stress disorder (PTSD) and hazardous alcohol use are highly comorbid. Research on integrated interventions to address PTSD symptoms and hazardous alcohol use concurrently has demonstrated efficacy, yet integrated treatments are underutilized. Both patient (e.g., stigma, scheduling/logistics) and clinician (e.g., concern about symptom exacerbation and/or treatment dropout) barriers may impede utilization of integrated interventions among those with comorbid PTSD symptoms and hazardous alcohol use. Primary care behavioral health models (PCBH), in which embedded behavioral health providers deliver treatment to individuals with mild or moderate behavioral health symptoms in primary care, may help address treatment barriers by offering accessible behavioral health interventions in a destigmatizing setting. This paper presents two case examples from a randomized controlled trial testing the efficacy of an integrated intervention for PTSD symptoms and hazardous alcohol use developed for and delivered in primary care. Outcome data and session-by-session content for two participants are included, along with discussion of barriers encountered during the course of treatment. Clinician-suggested strategies for navigating barriers to facilitate utilization of integrated interventions for PTSD symptoms and hazardous alcohol use are also discussed.

Formative evaluation prior to implementation of a brief treatment for posttraumatic stress disorder in primary care

BACKGROUND

Successful implementation of evidence-based treatments (EBT) for posttraumatic stress disorder (PTSD) in primary care may address treatment access and quality gaps by providing care in novel and less stigmatized settings. Yet, PTSD treatments are largely unavailable in safety net primary care. We aimed to collect clinician stakeholder data on organizational, attitudinal, and contextual factors relevant to EBT implementation.

METHODS

Our developmental formative evaluation was guided by the Consolidated Framework for Implementation Research (CFIR), including (a) surveys assessing implementation climate and attitudes towards EBTs and behavioral health integration and (b) semi-structured interviews to identify barriers and facilitators to implementation and need for augmentation. Participants were hospital employees (N = 22), including primary care physicians (n = 6), integrated behavioral health clinicians (n = 8), community wellness advocates (n = 3), and clinic leadership (n = 5). We report frequency and descriptives of survey data and findings from directed content analysis of interviews. We used a concurrent mixed-methods approach, integrating survey and interview data collected simultaneously using a joint display approach. A primary care community advisory board (CAB) helped to refine interview guides and interpret findings.

RESULTS

Stakeholders described implementation determinants of the EBT related to the CFIR domains of intervention characteristics (relative advantage, adaptability), outer setting (patient needs and resources), inner setting (networks and communication, relative priority, leadership engagement, available resources), and individuals involved (knowledge and beliefs, cultural considerations). Stakeholders described strong attitudinal support (relative advantage), yet therapist time and capacity restraints are major PTSD treatment implementation barriers (available resources). Changes in hospital management were perceived as potentially allowing for greater access to behavioral health services, including EBTs. Patient engagement barriers such as stigma, mistrust, and care preferences were also noted (patient needs and resources). Recommendations included tailoring the intervention to meet existing workflows (adaptability), system alignment efforts focused on improving detection, referral, and care coordination processes (networks and communication), protecting clinician time for training and consultation (leadership engagement), and embedding a researcher in the practice (available resources).

CONCLUSIONS

Our evaluation identified key CFIR determinants of implementation of PTSD treatments in safety net integrated primary care settings. Our project also demonstrates that successful implementation necessitates strong stakeholder engagement.

Determinants of effective treatment coverage for posttraumatic stress disorder: findings from the World Mental Health Surveys

BACKGROUND

Posttraumatic stress disorder (PTSD) is associated with significant morbidity, but efficacious pharmacotherapy and psychotherapy are available. Data from the World Mental Health Surveys were used to investigate extent and predictors of treatment coverage for PTSD in high-income countries (HICs) as well as in low- and middle-income countries (LMICs).

METHODS

Seventeen surveys were conducted across 15 countries (9 HICs, 6 LMICs) by the World Health Organization (WHO) World Mental Health Surveys. Of 35,012 respondents, 914 met DSM-IV criteria for 12-month PTSD. Components of treatment coverage analyzed were: (a) any mental health service utilization; (b) adequate pharmacotherapy; (c) adequate psychotherapy; and (d) effective treatment coverage. Regression models investigated predictors of treatment coverage.

RESULTS

12-month PTSD prevalence in trauma exposed individuals was 1.49 (S.E., 0.08). A total of 43.0% (S.E., 2.2) received any mental health services, with fewer receiving adequate pharmacotherapy (13.5%), adequate psychotherapy (17.2%), or effective treatment coverage (14.4%), and with all components of treatment coverage lower in LMICs than HICs. In a multivariable model having insurance (OR = 2.31, 95 CI 1.17, 4.57) and severity of symptoms (OR = .35, 95% CI 0.18, 0.70) were predictive of effective treatment coverage.

CONCLUSION

There is a clear need to improve pharmacotherapy and psychotherapy coverage for PTSD, particularly in those with mild symptoms, and especially in LMICs. Universal health care insurance can be expected to increase effective treatment coverage and therefore improve outcomes.

The Impact of COVID-19 on Psychotherapy Participation Among Individuals With Posttraumatic Stress Disorder Enrolled in Treatment Research

The onset of the COVID-19 pandemic disrupted many aspects of daily life and required a rapid and unprecedented shift in psychotherapy delivery from in-person to telemental health. In the present study, we explored the impact of the pandemic on individuals' ability to participate in posttraumatic stress disorder (PTSD) psychotherapy and the association between the impact of COVID-19 impact on health and financial well-being and psychotherapy participation. Participants (N = 161, 63.2% male, M_age = 42.7 years) were United States military veterans (n = 108), active duty military personnel (n = 12), and civilians (n = 6), who were participating in one of nine PTSD treatment trials. The results indicate a predominately negative COVID-19 impact on therapy participation, although some participants (26.1%) found attending therapy sessions through telehealth to be easier than in-person therapy. Most participants (66.7%) reported that completing in vivo exposure homework became harder during the pandemic. Moreover, the impact of the pandemic on PTSD symptom severity and daily stress were each associated with increased difficulty with aspects of therapy participation. The findings highlight the unique challenges to engaging in PTSD treatment during the pandemic as well as a negative impact on daily stress and PTSD severity, both of which were related to treatment engagement difficulties.

Engagement in and Benefits of a Short-Term, Brief Psychotherapy Intervention for PTSD During Pregnancy

Trauma-related symptoms and post-traumatic stress disorder (PTSD) are common during pregnancy and have adverse effects on pregnancy and birth outcomes, post-partum maternal mental health, and child development. The arousal symptoms associated with PTSD, including heightened or dysregulated physiology, may contribute to these adverse outcomes. Low-income minoritized women may be at highest risk given more lifetime exposure to trauma and limited access to mental health care. While evidence-based psychotherapies for PTSD exist, none are targeted to non-treatment seeking individuals nor specifically integrated with prenatal care. Thus, we developed and tested the efficacy of a short-term (four sessions) brief (30-45 min) psychotherapeutic intervention designed to address PTSD symptoms in pregnant women receiving prenatal care at two urban medical centers. Participants were 32 pregnant women with an average gestational age of 18.5 weeks at the time of enrollment. The sample was overwhelmingly non-Caucasian, single, and reported very low income. Participants completed measures of trauma-related symptoms (Post-traumatic Stress Disorder Checklist, PCL), and depression (Edinburgh post-natal Depression Scale, EPDS) at baseline, twice during treatment, post-treatment, and at 10-14 weeks post-partum. The intervention was successful at significantly decreasing symptoms of PTSD (PCL score = -20.27, 95% CI: -25.62, -14.92, P < 0.001, W = -7.43) and depression (EPDS score = -4.81, 95% CI: -7.55, -2.06, P = 0.001, W = -3.23) by the final session. These benefits were sustained at post-treatment and post-partum follow ups. Future research should further explore the effectiveness of this treatment in a randomized controlled trial.

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.

Condensed internet-delivered prolonged exposure provided soon after trauma: A randomised pilot trial

Exposure to trauma is common and may have detrimental psychological consequences. Brief exposure therapy provided early after trauma has shown encouraging results in promoting recovery. To scale up treatment availability, we developed a 3-week internet-delivered intervention comprised of four modules based on prolonged exposure (condensed internet-delivered prolonged exposure; CIPE) with therapist support. In this pilot study, we assessed the feasibility, acceptability, and preliminary efficacy of CIPE delivered within 2 months after the index event. Thirty-three participants were randomised to CIPE or a waiting list (WL). The frequency, vividness and distress of intrusive recollections or flashback memories of the traumatic event were assessed using an intrusive memory smartphone app. Symptoms of post-traumatic stress were assessed by the PTSD Symptom Checklist for DSM-5 (PCL-5). The most common index traumas in the sample were rape, interpersonal violence and life-threatening accidents. A majority of participants (82%) randomised to CIPE completed all modules, and the number of logins per participant to the Internet platform was high during the three-week intervention (M = 19.6, SD = 11.8). At post-treatment, the CIPE participants had a more favourable reduction than the WL group on the vividness and distress ratings, as well as on the PCL-5 sum score (bootstrapped d = 0.85; 95% CI [0.25-1.45]). Treatment effects were sustained at 6-months follow up and no severe adverse events associated with the intervention were found. CIPE seems to be a feasible and possibly efficacious early intervention after trauma. Large-scale trials are needed to assess its efficacy and long-term benefits.

Clinical considerations in designing brief exposure interventions for primary care behavioral health settings

INTRODUCTION

Prevalence rates of anxiety disorders and symptoms in primary care (PC) settings are very high. Behavioral health consultants in primary care behavioral health (PCBH) settings enable increased access to evidence-based anxiety treatment. Despite strong extant support for exposure-based therapy for anxiety disorders, the use of exposure to treat anxiety in PC settings is low. Although barriers to exposure therapy (ET) may be exacerbated in PC settings, many anxiety presentations in PC warrant an exposure-based approach to treatment. Thus, exploration of feasibility and efficacy of ET in PC represents a critical area for advancing evidence-based treatment of anxiety symptoms.

METHODS

The current article addresses this gap through the presentation of two case examples of ET conducted in PCBH. Theoretical and practical information regarding the implementation of exposure using a brief (≤ 30 min), time-limited (4-6 visit) approached are presented.

RESULTS

Results from the case examples demonstrate feasibility of conducting exposure in a brief format consistent with a PCBH approach. Additionally, patient outcomes presented suggest that ET conducted in PCBH reduces anxiety symptoms and may facilitate referral to specialty care settings.

DISCUSSION

Exposure may offer promise in improving the quality of anxiety treatment in PC. Future work documenting both effectiveness and implementation outcomes of exposure in PC in clinical work and research trials is needed. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Neural affective mechanisms associated with treatment responsiveness in veterans with PTSD and comorbid alcohol use disorder

Post-traumatic stress disorder (PTSD) is associated with neuro-physiological abnormalities reflecting increased anticipatory anxiety and reactivity to traumatic cues. It remains unclear whether neural mechanisms associated with PTSD treatment responsiveness, i.e. hyperactivation of the affective salience network in the brain, extend to a comorbid PTSD and substance use disorder population. Thirty-one Veterans with PTSD and co-occurring alcohol use disorder (AUD) were randomly assigned to either prolonged exposure or a non-exposure based treatment. They completed an affective anticipation task while undergoing fMRI, immediately prior and after completing treatment. After controlling for type and length of treatment, larger reduction of PTSD symptoms was associated with decreased anticipatory activation to negative trauma-related cues in the right pre-Supplementary Motor Area (pre-SMA), a region associated with emotion regulation. Smaller reduction in PTSD severity was associated with enhanced anticipatory activation to those cues within the right para-hippocampal region, an affective processing region. Our findings suggest that post-treatment reductions in anticipatory reactivity to trauma-related cues in the pre-SMA and para-hippocampal area are associated with larger PTSD symptom reduction in individuals with co-occurring PTSD and AUD. These results may offer neurofeedback training targets as an alternative to or enhancement of other PTSD treatment modalities in this population.

Implementing Prolonged Exposure Therapy for PTSD in a Context of Ongoing Adversity: A Clinical Case Study

Obstacles regarding the implementation of empirically supported treatments (ESTs) for mental disorders such as post-traumatic stress disorder (PTSD) still require further investigation. One notable obstacle is whether persons in low- and middle-income countries (LMICs) residing in a context of ongoing adversity would benefit from an EST for PTSD. We reflect on the utility of a brief prolonged exposure intervention at a primary care community-counseling center in South Africa. “Sam,” a 45-year-old, female was assessed at baseline, during treatment, postassessment, and at 3-month follow-up. At the beginning of treatment, Sam had a positive diagnosis for PTSD (PSSI-5 = 55, and cutoff is 23) and at the end of treatment (PSSI-5 = 17), and 3-month follow-up (PSSI-5 = 21), she had a negative diagnosis for PTSD. We reflect on the mediating effects that contextual factors such as gang violence had on the treatment process and the feasibility of implementing ESTs for PTSD in LMICs under conditions of ongoing adversity.

Posttraumatic stress disorder symptom clusters and substance use among patients with upper limb amputations due to traumatic injury

Purpose: Examining the relationship between posttraumatic stress disorder and posttraumatic stress disorder symptom clusters (re-experiencing, avoidance, hyperarousal, emotional numbing) on three substance use measures among individuals with upper limb amputation due to traumatic injury - an understudied population with high rates of posttraumatic stress disorder.Methods: Multi-site, cross-sectional design. Participants (N = 236) were recruited from seven prosthetic rehabilitation centres across the USA and completed measures of PTSD, alcohol use, prescription medication overuse, and illicit drug use.Results: Twenty-six percent of participants screened positive for posttraumatic stress disorder, 39% for problematic alcohol use, 12% for prescription medication overuse, and 7% for illicit drug use. No association was found between posttraumatic stress disorder or posttraumatic stress disorder symptoms clusters on problematic alcohol use. However, hyperarousal symptoms increased odds of overusing prescription medication (odds ratio = 3.30); further, a positive screen for posttraumatic stress disorder increased odds of illicit drug use (odds ratio = 2.95).Conclusions: These findings demonstrate the importance of assessing psychological well-being and a variety of substance use behaviours following amputation from traumatic injury. These findings may also provide clinically-relevant targets for prevention and intervention regarding prescription medication and illicit substance use, such as incorporating evidence-based treatment for posttraumatic stress disorder hyperarousal symptoms (e.g., prolonged exposure) and/or integrated treatment for posttraumatic stress-substance misuse (e.g., Seeking Safety) into patients' long-term inpatient/outpatient rehabilitation plans.Implications for rehabilitationPosttraumatic stress disorder hyperarousal symptoms increased odds of overusing prescription medication among individuals with upper limb amputation due to traumatic injury; a positive screen for posttraumatic stress disorder increased odds of illicit drug use.Psychological assessments should be incorporated into treatment and rehabilitation plans following amputation from traumatic injury.Rehabilitation specialists should consider adding or integrating evidence-based treatment for posttraumatic stress disorder into patients' long-term rehabilitation plan to reduce risk for problematic substance use.Findings support calls by the Centre for Disease Control and Prevention to overhaul prescription medication guidelines, including the need to assess risk and address harms concerning overuse of prescription medication.
