Mental Health Clinician Practices and Perspectives on Treating Adults with Co-Occurring Posttraumatic Stress and Substance Use Disorders

OBJECTIVE

Posttraumatic stress disorder (PTSD) and substance use disorders (SUD) commonly co-occur and represent a complex, challenging clinical comorbidity. Meta-analytic studies and systematic reviews suggest that trauma-focused treatments are more efficacious than non-trauma focused interventions for co-occurring PTSD/SUD. However, relatively little is known about mental health clinicians' practices or preferences for treating co-occurring PTSD/SUD. The present study aimed to describe the current clinical practices of mental health clinicians who treat PTSD and/or SUD-related conditions and to assess interest in novel integrative treatments for PTSD/SUD.

METHODS

Licensed mental health clinicians (N = 76; Mage = 39.59, SD = 8.14) who treat PTSD and/or SUD completed an anonymous online survey from April 2021 to July 2021.

RESULTS

The majority (61.8%) of clinicians reported using integrative treatments for PTSD/SUD. The most commonly used trauma-focused treatments were 1) Cognitive Processing Therapy (CPT: 71.1%) and 2) Prolonged Exposure Therapy (PE: 68.4%) for PTSD. Approximately half (51.3%) of clinicians endorsed using Relapse Prevention (RP) for SUD. The vast majority (97.4%) of clinicians were somewhat or very interested in a new integrative CPT-RP intervention, and 94.7% of clinicians believed patients would be interested in a CPT-RP intervention. In the absence of an available evidence-based integrative treatment using CPT, 84.0% of clinicians reported modifying extant treatment protocols on their own to address PTSD and SUD concurrently.

CONCLUSIONS

The findings demonstrate mental health clinician support of integrative treatments for PTSD/SUD. The most commonly used trauma-focused intervention was CPT and clinicians expressed strong interest in an integrative intervention that combines CPT and RP. Implications for future treatment development are discussed.

Benchmarking quality of life to posttraumatic stress disorder symptom changes in cognitive processing therapy

Although there is ample evidence that PTSD is effectively treated by first-line therapies such as Cognitive Processing Therapy (CPT), it is less clear to what degree these treatments improve quality of life (QOL), a common presenting concern of treatment-seeking individuals (Rosen et al., 2013). Only two studies, both conducted in military veteran samples, have examined the magnitude of PTSD symptom change needed in order to achieve corresponding changes in QOL during treatment. The current study aimed to replicate and extend these two previous studies by benchmarking multi-faceted QOL in a civilian sample of primarily female interpersonal violence survivors (N = 115) treated with CPT. We grouped participants into categories of increasingly greater PTSD symptom change: no response, response, loss of diagnosis, and remission. Outcomes were clinically meaningful change and good endpoint across five measures of QOL. Some QOL measures showed clinically meaningful change and/or good endpoint after a response to treatment or loss of diagnosis, but only remission from PTSD was associated with both clinically meaningful change and a good endpoint across all QOL indicators. These findings add to the emerging literature showing that treating PTSD to remission may maximize the likelihood of improvements in quality of life.

730 Prevalence and impact of sleep problems in active duty military personnel receiving Cognitive Processing Therapy for PTSD

Introduction

Sleep disturbances are common in active duty military personnel and play a key role in the development and maintenance of posttraumatic stress disorder (PTSD). Research indicates that although insomnia and nightmares improve with successful PTSD treatment, they may remain clinically significant. Few previous PTSD studies have assessed sleep disorder constructs using validated instruments. The objectives of this study were to examine the proportion of active duty military personnel seeking treatment for PTSD who reported clinically significant insomnia, nightmares, sleep duration, and excessive daytime sleepiness and to examine the impact PTSD treatment had on these sleep constructs using validated self-report questionnaires.

Methods

Sleep was evaluated in 223 active duty service members participating in a randomized clinical trial comparing group and individual Cognitive Processing Therapy (CPT) for PTSD. Sleep constructs were assessed using the Insomnia Severity Index (ISI), Trauma-Related Nightmare Survey (TRNS), Self-Assessment of Sleep (SAS), and Epworth Sleepiness Scale (ESS) at baseline and 2 weeks posttreatment.

Results

At baseline, 82% of participants reported clinically significant insomnia and 75% reported at least 1 moderately severe nightmare per week. Participants reported averaging 4.76 hours of sleep per night, and 65% reported excessive daytime sleepiness. Over the course of PTSD treatment, there were statistically significant improvements in insomnia, nightmares, and excessive daytime sleepiness, but scores remained in clinically significant ranges. Minimal increases were seen in sleep duration. Of the participants who no longer met criteria for PTSD at posttreatment, 50% continued to report clinically significant insomnia, 52% continued to report clinically significant nightmares, and 44% continued to report excessive daytime sleepiness.

Conclusion

Consistent with previous research, sleep problems persisted for a significant number of service members who completed treatment for PTSD. Insomnia, nightmare, and sleep extension interventions are likely an important part of comprehensive PTSD treatment plans.

1073 Sleep Disorders Contribute To Anger In Service Members With Posttraumatic Stress Disorder

Introduction

The emotion of anger and behavioral acts of aggression can lead to severe negative consequences, including family violence, legal charges, and death. Anger can be a symptom of posttraumatic stress disorder (PTSD), particularly in service members. Service members report difficulties managing their anger and trouble with the subsequent results. Factors that differentiate service members with PTSD who have anger related problems from those who do not are still unknown. Impaired sleep is associated with negative mood states in the general population and may be a risk factor for anger in those with PTSD. This project examines how sleep disorders commonly diagnosed in service members (i.e., obstructive sleep apnea and insomnia) relate to PTSD and anger.

Methods

Ninety-three service members with comorbid PTSD, insomnia, and nightmares (mean age = 35.86 years, SD = 8.38, 27% female, 45% white) completed polysomnography and other measures as part of a clinical trial. A multiple regression model examined how total Apnea Hypopnea Index (AHI), AHI during REM sleep, insomnia (Insomnia Severity Index), age, and race related to PTSD symptoms (Clinical Administered PTSD Scale-5: CAPS-5). A second multiple regression model examined the same variables’ associations with anger (Dimensions of Anger Reactions-5; DAR-5).

Results

More than a third of the sample (37%) met criteria for OSA (AHI scores>5) and 99% met criteria for insomnia (ISI>10). Total AHI and REM AHI were not associated with CAPS-5 scores or ISI. Across OSA and PSG indices, only greater REM AHI (b=.07, p<.05) and Insomnia (b=.43, p<.05) were positively associated with DAR-5 anger scores. Total AHI was unrelated to anger.

Conclusion

Elevated REM AHI and insomnia were associated with greater anger in service members with PTSD. Current treatments for anger are only moderately effective. Assessing and treating comorbid sleep disorders may reduce anger and enhance successful PTSD treatment.

Message Delivery for the Treatment of Posttraumatic Stress Disorder: Longitudinal Observational Study of Symptom Trajectories

Background

Individuals with posttraumatic stress disorder (PTSD) face symptoms that can hinder access to treatment, such as avoidance and guilt. Telemedicine offers a technological solution to increase access to mental health care and overcome barriers to treatment. Although an increasing body of literature focused on synchronous telehealth (eg, live video), no studies have examined the delivery of PTSD treatment via two-way multimedia messages (ie, texting or messaging).

Objective

The aim of this study was to conduct a longitudinal observation of treatment for PTSD delivered using two-way asynchronous messaging. We also sought to identify individual and treatment characteristics that could predict the observed outcome differences.

Methods

Outpatients diagnosed with PTSD (N=475) received interventions from licensed therapists, which were delivered via messaging once or more than once per day, 5 days a week for 12 weeks. PTSD symptoms were assessed every 3 weeks using the PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders-5. Trajectories of PTSD symptoms were identified using growth mixture modeling (GMM). Using logistic regression, the demographic, treatment, and messaging characteristics of patient groups that improved were compared with the characteristics of patient groups that did not improve.

Results

The GMM identified 4 trajectories of PTSD symptoms: moderate improvement (197/475, 41.4%), high symptoms (197/475, 41.4%), chronic symptoms (61/475, 12.9%), and acute improvement (20/475, 4.3%). Patients with a clinically significant reduction in PTSD symptoms (231/475, 48.6%) were more likely to communicate via video (odds ratio [OR] 1.01, 95% CI 1.01-1.05; P=.03), have a higher working alliance with their therapist (OR 1.03, 95% CI 1.01-1.05; P=.02), and be at their first treatment experience (OR 2.03, 95% CI 1.18-3.54; P=.01). Treatment adherence was associated with greater therapeutic alliance (OR 1.07, 95% CI 1.03-1.10; P<.001), education (OR 2.13, 95% CI 1.13-4.03; P=.02), and more patient-generated messages per week (OR 1.08, 95% CI 1.04-1.13; P<.001).

Conclusions

Multimedia message delivery for PTSD treatment showed symptom-reduction rates similar to traditional forms of treatment delivery, suggesting further study of messaging as a treatment medium. Most patients completed an 8-week course, reflecting the acceptability of messaging interventions. Delivering treatment via two-way messaging offers increased opportunities for widespread access to mental health care.

Reduced Salience and Enhanced Central Executive Connectivity Following PTSD Treatment

Background

In soldiers with posttraumatic stress disorder, symptom provocation was found to induce increased connectivity within the salience network, as measured by functional magnetic resonance imaging and global brain connectivity with global signal regression (GBCr). However, it is unknown whether these GBCr disturbances would normalize following effective posttraumatic stress disorder treatment.

Methods

Sixty-nine US Army soldiers with (n = 42) and without posttraumatic stress disorder (n = 27) completed functional magnetic resonance imaging at rest and during symptom provocation using subject-specific script imagery. Then, participants with posttraumatic stress disorder received six weeks (12 sessions) of group cognitive processing therapy or present-centered therapy. At week 8, all participants repeated the functional magnetic resonance imaging scans. The primary analysis used a region-of-interest approach to determine the effect of treatment on salience GBCr. A secondary analysis was conducted to explore the pattern of GBCr alterations posttreatment in posttraumatic stress disorder participants compared to controls.

Results

Over the treatment period, present-centered therapy significantly reduced salience GBCr (p = .02). Compared to controls, salience GBCr was high pretreatment (present-centered therapy, p = .01; cognitive processing therapy, p = .03) and normalized post-present-centered therapy (p = .53) but not postcognitive processing therapy (p = .006). Whole-brain secondary analysis found high GBCr within the central executive network in posttraumatic stress disorder participants compared to controls. Post hoc exploratory analyses showed significant increases in executive GBCr following cognitive processing therapy treatment (p = .01).

Conclusion

The results support previous models relating cognitive processing therapy to central executive network and enhanced cognitive control while unraveling a previously unknown neurobiological mechanism of present-centered therapy treatment, demonstrating treatment-specific reduction in salience connectivity during trauma recollection.

Homework Completion, Patient Characteristics, and Symptom Change in Cognitive Processing Therapy for PTSD

We evaluated the impact of homework completion on change in PTSD symptoms in the context of two randomized controlled trials of Cognitive Processing Therapy for PTSD (CPT). Female participants (n = 140) diagnosed with PTSD attended at least one CPT session and were assigned homework at each session. The frequency of homework completion was assessed at the beginning of each session and PTSD symptoms were assessed every other session. Piecewise growth models were used to examine the relationship between homework completion and symptom change. CPT version (with vs without the written trauma account) did not moderate associations between homework engagement and outcomes. Greater pretreatment PTSD symptoms predicted more Session 1 homework completion, but PTSD symptoms did not predict homework completion at other timepoints. More homework completion after Sessions 2 and 3 was associated with less change in PTSD from Session 2 to Session 4, but larger pre-to-post treatment changes in PTSD. Homework completion after Sessions 2 and 3 was associated with greater symptom change among patients who had fewer years of education. More homework completion after Sessions 8 and 9 was associated with larger subsequent decreases in PTSD. Average homework completion was not associated with client characteristics. In the second half of treatment, homework engagement was associated with less dropout. The results suggest that efforts to increase engagement in homework may facilitate symptom change.

TELEMEDICINE VERSUS IN-PERSON DELIVERY OF COGNITIVE PROCESSING THERAPY FOR WOMEN WITH POSTTRAUMATIC STRESS DISORDER: A RANDOMIZED NONINFERIORITY TRIAL

BACKGROUND

This study examined the effectiveness of telemedicine to provide psychotherapy to women with posttraumatic stress disorder (PTSD) who might be unable to access treatment. Objectives were to compare clinical and process outcomes of PTSD treatment delivered via videoteleconferencing (VTC) and in-person (NP) in an ethnically diverse sample of veteran and civilian women with PTSD.

METHODS

A randomized controlled trial of Cognitive Processing Therapy, an evidence-based intervention for PTSD, was conducted through a noninferiority design to compare delivery modalities on difference in posttreatment PTSD symptoms. Women with PTSD, including 21 veterans and 105 civilians, were assigned to receive psychotherapy delivered via VTC or NP. Primary treatment outcomes were changes in PTSD symptoms in the completer sample.

RESULTS

Improvements in PTSD symptoms in the VTC condition (n = 63) were noninferior to outcomes in the NP condition (n = 63). Clinical outcomes obtained when both conditions were pooled together (N = 126) demonstrated that PTSD symptoms declined substantially posttreatment (mean = -20.5, 95% CI -29.6 to -11.4) and gains were maintained at 3- (mean = -20.8, 95% CI -30.1 to -11.5) and 6-month followup (mean = -22.0, 95% CI -33.1 to -10.9. Veterans demonstrated smaller symptom reductions posttreatment (mean = -9.4, 95% CI -22.5 to 3.7) than civilian women (mean = -22.7, 95% CI -29.9 to -15.5.

CONCLUSIONS

Providing psychotherapy to women with PTSD via VTC produced outcomes comparable to NP treatment. VTC can increase access to specialty mental health care for women in rural or remote areas.

Cognitive processing therapy for posttraumatic stress disorder delivered to rural veterans via telemental health: a randomized noninferiority clinical trial

OBJECTIVE

To compare clinical and process outcomes of cognitive processing therapy-cognitive only version (CPT-C) delivered via videoteleconferencing (VTC) to in-person in a rural, ethnically diverse sample of veterans with posttraumatic stress disorder (PTSD).

METHOD

A randomized clinical trial with a noninferiority design was used to determine if providing CPT-C via VTC is effective and "as good as" in-person delivery. The study took place between March 2009 and June 2013. PTSD was diagnosed per DSM-IV. Participants received 12 sessions of CPT-C via VTC (n = 61) or in-person (n = 64). Assessments were administered at baseline, midtreatment, immediately posttreatment, and 3 and 6 months posttreatment. The primary clinical outcome was posttreatment PTSD severity, as measured by the Clinician-Administered PTSD Scale.

RESULTS

Clinical and process outcomes found VTC to be noninferior to in-person treatment. Significant reductions in PTSD symptoms were identified at posttreatment (Cohen d = 0.78, P < .05) and maintained at 3- and 6-month follow-up (d = 0.73, P < .05 and d = 0.76, P < .05, respectively). High levels of therapeutic alliance, treatment compliance, and satisfaction and moderate levels of treatment expectancies were reported, with no differences between groups (for all comparisons, F < 1.9, P > .17).

CONCLUSIONS

Providing CPT-C to rural residents with PTSD via VTC produced outcomes that were "as good as" in-person treatment. All participants demonstrated significant reductions in PTSD symptoms posttreatment and at follow-up. Results indicate that VTC can offer increased access to specialty mental health care for residents of rural or remote areas.

Prediction of numbing and effortful avoidance in female rape survivors with chronic PTSD

The purpose of the present study was to investigate the relationships among numbing, arousal, intrusion, and avoidance in a sample of 272 female rape survivors. Multiple regression analyses were conducted to test a theoretical model, which posits that hyperarousal and numbing are functionally related mechanisms and intrusions and avoidance are functionally related. Results supported the hypothesis that arousal explained the majority of the variance in numbing beyond that explained by avoidance and intrusion. In addition, intrusive symptoms explained the majority of the variance in effortful avoidance beyond that explained by numbing and arousal. The findings suggest that numbing and effortful avoidance may be separate mechanisms associated with symptoms of arousal and intrusion, respectively.

Cognitive mediation of childhood maltreatment and adult depression in recent crime victims

Childhood maltreatment has been linked to adult depressive disorders. However, few studies have examined mechanisms through which childhood maltreatment may contribute to adult depression. Thus, we examined the role of one potential mechanism of this relationship, maladaptive cognitions, in a recently traumatized sample. Participants were adult women who had been recently raped (n = 133) or physically assaulted (n = 73). We examined whether maladaptive self-and other-cognitions mediated relationships between childhood sexual, physical, and emotional abuse and current depression. Relationships between childhood sexual abuse and both current depression symptoms and diagnosis were mediated by maladaptive cognitions about self. Relationships between both childhood sexual abuse and childhood physical abuse and adult depressive symptoms were mediated by maladaptive cognitions about others.

Development of a criteria set and a structured interview for disorders of extreme stress (SIDES)

Data regarding the development of a structured interview measuring alterations that may accompany extreme stress are presented. A list of 27 criteria often seen in response to extreme trauma and not addressed by DSM-IV criteria for posttraumatic stress disorder (PTSD) were generated based on a systematic review of the literature and a survey of 50 experts. A structured interview for disorders of extreme stress (SIDES) measuring the presence of these criteria was administered to 520 subjects as part of the DSM-IV PTSD field trials. Inter-rater reliability as measured by Kappa coefficients for lifetime Disorders of Extreme Stress was .81. Internal consistency using coefficient alpha ranged from .53 to .96. Results indicate that the SIDES is a useful tool for investigation of response to extremes stress.
