Implementing Prolonged Exposure Therapy in a Community Substance Use Treatment Program: A Qualitative Study.

INTRODUCTION: Post-traumatic stress disorder (PTSD) commonly co-occurs with substance use disorders (SUD), yet few community-based SUD programs incorporate evidence-based trauma-focused. Prolonged exposure (PE), including its massed format (M-PE) with session frequency of 3-4 times per week, is a gold standard intervention for PTSD; however, concerns about client readiness, logistical demands and relapse risk have limited its adoption within SUD settings. This study examined staff perspectives on the feasibility and acceptability of integrating M-PE into a community-based SUD program. METHODS: Prior to launching a Hybrid Type 1 effectiveness-implementation trial (Project COMET), we conducted semi-structured virtual interviews with 15 community clinic staff: providers (n = 8), administrators (n = 2) and peer specialists (n = 5). Interviews were recorded, transcribed and analysed using a rapid qualitative analysis framework with matrix techniques to compare themes across roles. RESULTS: Four overarching themes captured staff perspectives on integrating M-PE: (Theme 1) Prior Knowledge and Experiences: Most staff were familiar with EMDR, while direct knowledge of PE/M-PE was limited. (Theme 2) Perceptions of M-PE: M-PE was widely viewed as a promising, structured intervention that fits the pacing and duration of SUD care. (Theme 3) Symptom Reduction and Client Impact: Staff anticipated improvements in PTSD and SUD symptoms through trauma-focused treatment. (Theme 4) Barriers and Constraints: Participants identified several potential implementation challenges, including logistical barriers and client readiness. DISCUSSION AND CONCLUSIONS: Findings suggest that staff generally viewed M-PE favourably but emphasised the importance of ensuring client readiness and organisational support. Enhancing feasibility and long-term sustainability may require expanded psychoeducation, targeted provider training and flexible delivery models. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT06968832.

Five-year outcomes in a randomised controlled trial of prolonged exposure therapy and supportive counselling for post-traumatic stress disorder in adolescents: a task-shifted intervention.

BACKGROUND: Cognitive-behavioural therapies with a trauma focus are effective in reducing posttraumatic stress disorder and other psychological distress in adolescents. Long-term follow-up data on adolescents treated for PTSD remain scarce, with few studies extending beyond 12 months after treatment completion. OBJECTIVE: To evaluate the maintenance of treatment gains in a comparative study of effectiveness of PE-A and SC up to 60 months post-treatment. METHOD: Sixty-three adolescents diagnosed with PTSD were randomly assigned to either treatment, provided by newly trained and supervised non-specialist health workers. The primary outcome measure was PTSD symptom severity, as independently assessed on the Child PTSD Symptom Scale (CPSS). We report on the 60-month post-treatment follow-up, building on post-treatment, 3-month, 6-month, 12-month and 24-month post-treatment data that have been published previously. RESULTS: Participants in both treatment groups maintained a significant reduction in PTSD symptoms up to 60-months post-treatment (F (7, 343)&#x2009;=&#x2009;2.86, p&#x2009;<&#x2009;.01). Participants receiving prolonged exposure experienced greater improvement on the CPSS at all follow-up assessment timepoints, except for the 60-month FU (p&#x2009;=&#x2009;.28; g&#x2009;=&#x2009;0.33). CONCLUSION: Adolescents with PTSD continued to maintain treatment gains up to 60-months post-treatment. These data, along with findings from the original RCT, indicate that a brief treatment protocol (averaging 9 sessions of PE-A or SC) in a LMIC, task-shifted to be delivered by nurses without prior psychotherapy experience, led to lasting improvements in PTSD and comorbid symptoms for up to five years. The sustained benefits and improved functioning over the first few years post-treatment support expanding both treatments, especially PE-A, in community settings.

Changes in PTSD patients' narratives during prolonged exposure therapy: a replication and extension.

Following E. B. Foa, C. Molnar, and L. Cashman (1995), narrative changes from the first to the last exposure session were compared for improved and nonimproved PTSD patients on fragmentation, organization, internal, and external events. Improved (n = 8) and nonimproved (n = 12) patients did not differ regarding changes in fragmentation or organized thoughts. However, improved patients showed a greater decrease in disorganized thoughts during treatment. Furthermore, all patients, independent of improvement, showed significant changes in the same direction; a decrease in disorganized thoughts and external events and an increase in internal events. Although previous results were partly replicated, it is concluded that narrative changes may be due to exposure treatment itself rather than to changes in memory representation.

A comparison of cognitive-processing therapy with prolonged exposure and a waiting condition for the treatment of chronic posttraumatic stress disorder in female rape victims.

The purpose of this study was to compare cognitive-processing therapy (CPT) with prolonged exposure and a minimal attention condition (MA) for the treatment of posttraumatic stress disorder (PTSD) and depression. One hundred seventy-one female rape victims were randomized into 1 of the 3 conditions, and 121 completed treatment. Participants were assessed with the Clinician-Administered PTSD Scale, the PTSD Symptom Scale, the Structured Clinical Interview for DSM-IV, the Beck Depression Inventory, and the Trauma-Related Guilt Inventory. Independent assessments were made at pretreatment, posttreatment, and 3 and 9 months posttreatment. Analyses indicated that both treatments were highly efficacious and superior to MA. The 2 therapies had similar results except that CPT produced better scores on 2 of 4 guilt subscales.

Treatment of posttraumatic stress disorder by exposure and/or cognitive restructuring: a controlled study.

BACKGROUND: Unanswered questions from controlled studies of posttraumatic stress disorder concern the value of cognitive restructuring alone without prolonged exposure therapy and whether its combination with prolonged exposure is enhancing. METHODS: In a controlled study, 87 patients with posttraumatic stress disorder of at least 6 months' duration were randomly assigned to have 10 sessions of 1 of 4 treatments: prolonged exposure (imaginal and live) alone; cognitive restructuring alone; combined prolonged exposure and cognitive restructuring; or relaxation without prolonged exposure or cognitive restructuring. RESULTS: Integrity of audiotaped treatment sessions was satisfactory when rated by an assessor unaware of the treatment assignment. Seventy-seven patients completed treatment. The pattern of results was similar regardless of rater, statistical method, measure, occasion, and therapist. Exposure and cognitive restructuring, singly or combined, improved posttraumatic stress disorder markedly on a broad front. Gains continued to 6-month follow-up and were significantly greater than the moderate improvement from relaxation. CONCLUSION: Both prolonged exposure and cognitive restructuring were each therapeutic on their own, were not mutually enhancing when combined, and were each superior to relaxation.

Bethanechol chloride as a suggested adjunct to prolonged in vivo exposure therapy in the treatment of paruresis.

A major difficulty in treating paruresis (psychogenic urinary retention) by prolonged in vivo exposure therapy involves the individual's inability to initiate urination in response to anxiety-provoking stimuli easily and frequently enough to generalize the desired behavior to everyday situations. Administration of bethanechol chloride, a parasympathomimetic compound that facilitates urination by prompting contraction of the detrusor muscle of the bladder, prior to therapeutic sessions is suggested to enhance the efficiency and effectiveness of in vivo desensitization procedures in the treatment of paruresis.

Cognitive-behavior therapy for PTSD in rape survivors.

In recent years, new data have appeared, further suggesting the utility of cognitive-behavioral interventions for posttraumatic stress disorder (PTSD) subsequent to sexual assault. In this article, we present a model of cognitive-behavioral treatment (CBT) for PTSD in rape survivors. Emotional-processing theory, which proposes mechanisms that underlie the development of disturbances following rape, is reviewed. A CBT-based therapy (Prolonged Exposure) is presented that entails education about common reactions to trauma, relaxation training, imaginal reliving of the rape memory, exposure to trauma reminders, and cognitive restructuring. Current research regarding the use of prolonged exposure is discussed. The case example of a young female rape survivor is described in detail, and her prior substance dependence and intense shame are highlighted. The therapy was successful in reducing the client's symptoms of PTSD, as well as her depressive symptoms, and these gains were maintained at a one-year follow-up assessment.

How well does cognitive-behavioral therapy treat symptoms of complex PTSD? An examination of child sexual abuse survivors within a clinical trial.

Are brief cognitive-behavioral treatments for posttraumatic stress disorder (PTSD) also effective for the wider range of symptoms conceptualized as complex PTSD? Female rape victims, most of whom had extensive histories of trauma, were randomly assigned to cognitive-processing therapy, prolonged exposure, or a delayed-treatment waiting-list condition. After determining that both types of treatment were equally effective for treating complex PTSD symptoms, we divided the sample of 121 participants into two groups depending upon whether they had a history of child sexual abuse. Both groups improved significantly over the course of treatment with regard to PTSD, depression, and the symptoms of complex PTSD as measured by the Trauma Symptom Inventory. Improvements were maintained for at least 9 months. Although there were group main effects on the Self and Trauma factors, there were no differences between the two groups at posttreatment once pretreatment scores were covaried. These findings indicate that cognitive-behavioral therapies are effective for patients with complex trauma histories and symptoms patterns.

Posttraumatic stress disorder: a state-of-the-science review.

This article reviews the state-of-the-art research in posttraumatic stress disorder (PTSD) from several perspectives: (1) Sex differences: PTSD is more frequent among women, who tend to have different types of precipitating traumas and higher rates of comorbid panic disorder and agoraphobia than do men. (2) Risk and resilience: The presence of Group C symptoms after exposure to a disaster or act of terrorism may predict the development of PTSD as well as comorbid diagnoses. (3) Impact of trauma in early life: Persistent increases in CRF concentration are associated with early life trauma and PTSD, and may be reversed with paroxetine treatment. (4) Imaging studies: Intriguing findings in treated and untreated depressed patients may serve as a paradigm of failed brain adaptation to chronic emotional stress and anxiety disorders. (5) Neural circuits and memory: Hippocampal volume appears to be selectively decreased and hippocampal function impaired among PTSD patients. (6) Cognitive behavioral approaches: Prolonged exposure therapy, a readily disseminated treatment modality, is effective in modifying the negative cognitions that are frequent among PTSD patients. In the future, it would be useful to assess the validity of the PTSD construct, elucidate genetic and experiential contributing factors (and their complex interrelationships), clarify the mechanisms of action for different treatments used in PTSD, discover ways to predict which treatments (or treatment combinations) will be successful for a given individual, develop an operational definition of remission in PTSD, and explore ways to disseminate effective evidence-based treatments for this condition.

Contextualizing trauma: using evidence-based treatments in a multicultural community after 9/11.

The mental health community was caught unaware after 9/11 with respect to treatment of survivors of terrorist attacks. Because this form of trauma was quite rare in the U.S., few trauma specialists had extensive experience, or taught regularly on this subject. Since the primary objective of terrorism is the creation of demoralization, fear, and uncertainty in the general population, a focus on mental health from therapeutic and public health perspectives is critically important to successful resolution of the crisis. Surveys after 9/11 showed unequivocally that symptomatology related to the attacks were found in hundreds of thousands of people, most of whom were not escapees or the families of the deceased. Soon after 9/11, our center formed a collaboration with other academic sites in Manhattan to rapidly increase capacity for providing state-of-the-art training and treatment for trauma-related psychiatric problems. Our experience suggests that evidence-based treatments such as Prolonged Exposure Therapy have proven successful in treating 9/11-related PTSD. However, special clinical issues have arisen, such as the influence of culture on clinical presentation and treatment expectations in a multiethnic community; the need to focus on more subtle aspects of relative risk appraisal in examining trauma-related avoidance; the range of changes in daily life that constitute adaptation to ongoing threat; the difficulties in working as a therapist who is also a member of the traumatized community; and grappling with multiple secondary consequences of 9/11 such as unemployment, work relocation, grief, and apocalyptic fears leading to a dramatically foreshortened vision of the future.

Relation between outcome and the patient's initial experience of the therapist and therapeutic conditions in four treatment methods for phobic disorders.

One hundred and three phobic women not suitable for insight-oriented psychotherapy were randomized to either therapist-directed prolonged exposure therapy (PE), supportive therapy of dynamic type (ST), relaxation therapy (R), or basal therapy (B). Immediately after seeing their therapist for history taking and beginning of treatment, the patients were asked to report their experience of the therapist, of themselves in relation to the therapist, and of the therapy (Experience of Therapy Inventory, ETI). The patients were informed that the therapists would not see the ETI. The patients were rated by an independent rater with regard to symptoms and functions at the beginning of treatment, at termination of treatment 3 months later, and at a follow-up 1 year after the commencement of the study. 1) Patients treated with PE and R were more satisfied with their therapists than patients treated with ST or B. The PE patients considered their therapists provided better contact, were more assured and knowledgeable, and gave what seemed to be the correct therapy, the R patients considered their therapist showed more warmth. Both PE and R patients felt their therapists were more interested than the ST and B therapists. These differences were probably due to differences in the amount of time offered, in the attitudes of the therapists, and in the characteristics of the therapies. 2) In the PE group there were positive associations between outcome and the initial experience of the therapist. There is, thus, empirical evidence that a good therapist-patient relation is of importance to a good outcome in this type of behaviour therapy. In the ST group there was an association between a good outcome and a positive experience of the rather conflict-centred beginning of the procedure. A positive experience of a conflict-centred approach may thus be regarded as an indication for dynamic therapy.

Trauma-focused psychotherapy after a trial of medication for chronic PTSD: pilot observations.

BACKGROUND: To date, all clinical trials using a single therapeutic modality (psychotherapy or pharmacotherapy) have found that even the best validated treatments for adults with chronic Posttraumatic Stress Disorder (PTSD) leave a substantial proportion of patients with disabling residual symptoms. METHOD: We reviewed the treatment course of three research patients with PTSD who received trauma-focused psychotherapy after experiencing a partial response to medication. Structured diagnostic interviews, validated symptom measures, and standardized treatment approaches were used to assess treatment response. RESULTS: All patients partially benefited from medication treatment, and the degree of benefit varied substantially. Also, all patients experienced an additional reduction in PTSD symptoms after a time-limited course of prolonged exposure therapy (PE). This finding differs from anecdotal observations among U.S. War veterans and has never been documented systematically among civilian adults with chronic PTSD. CONCLUSION: Maximizing treatment outcome in adults with chronic PTSD may require additional psychotherapy after a partial medication response, and further study is warranted.

Serum HER-2/neu conversion to positive at the time of disease progression in patients with breast carcinoma on hormone therapy.

BACKGROUND: Prolonged exposure of breast carcinoma cells in vitro to tamoxifen results in tamoxifen resistance. Tamoxifen-resistant cells express increased HER-2/neu mRNA and protein. The objective of this study was to determine whether patients with metastatic or locally advanced breast carcinoma who have negative serum HER-2/neu status at the initiation of first-line hormone therapy with letrozole or tamoxifen convert to positive serum HER-2/neu status at the time of disease progression and to determine whether serum HER-2/neu conversion to positive status is associated with response to therapy and overall survival. METHODS: Serum samples were obtained at baseline and at the time of disease progression from 240 patients who initially had negative serum HER-2/neu status (< 15 ng/mL). A manual microtiter, enzyme-linked immunosorbent assay that was specific for the extracellular domain of the HER-2/neu (c-erbB-2) oncoprotein product was used to quantitate serum levels. RESULTS: Among 240 patients, 61 patients (26%) converted from serum HER-2/neu negative to positive (> 15 ng/mL) at the time of disease progression. Thirty-two of 129 patients (25%) who were treated with tamoxifen and 29 of 111 patients (26%) who were treated with letrozole became converted to positive serum HER-2/neu status at the time of disease progression. The response rate and the time to disease progression on first-line hormone therapy were not affected by serum HER-2/neu conversion. The survival of patients who converted to positive serum HER-2/neu status was significantly shorter compared with the survival of patients who remained negative for serum HER-2/neu. A multivariate analysis revealed that conversion to positive serum HER-2/neu status was an independent prognostic variable for survival. CONCLUSIONS: Conversion to positive serum HER-2/neu status occurred in approximately 25% of patients who received first-line hormone therapy. Conversion to serum HER-2/neu-positive status occurred with equal frequency in antiestrogen and aromatase-inhibitor therapy. The current results showed that serum conversion to HER-2/neu-positive status was an independent risk factor for decreased survival in patients with breast carcinoma.

Pattern of change in prolonged exposure and cognitive-processing therapy for female rape victims with posttraumatic stress disorder.

Curve estimation techniques were used to identify the pattern of therapeutic change in female rape victims with posttraumatic stress disorder (PTSD). Within-session data on the Posttraumatic Stress Disorder Symptom Scale were obtained, in alternate therapy sessions, on 171 women. The final sample of treatment completers included 54 prolonged exposure (PE) and 54 cognitive-processing therapy (CPT) completers. For both PE and CPT, a quadratic function provided the best fit for the total PTSD, reexperiencing, and arousal scores. However, a difference in the line of best fit was observed for the avoidance symptoms. Although a quadratic function still provided a better fit for the PE avoidance, a linear function was more parsimonious in explaining the CPT avoidance variance. Implications of the findings are discussed.

Resolution of trauma-related guilt following treatment of PTSD in female rape victims: a result of cognitive processing therapy targeting comorbid depression?

BACKGROUND AND METHODS: Although Resick et al. [Resick, P.A., Nishith, P., Weaver, T.L., Astin, M.C., Feuer, C.A., 2002. A comparison of cognitive-processing therapy with prolonged exposure and a waiting condition for the treatment of chronic posttraumatic stress disorder in female rape victims. J. Consult. Clin. Psychol. 70, 867-879.] reported comparable results for treating rape-related posttraumatic stress disorder (PTSD) using either cognitive-processing therapy (CPT) or prolonged exposure (PE), there was some suggestion that CPT resulted in better outcomes than PE for certain aspects of trauma-related guilt. The present study revisited these findings to examine whether this effect was a function of improvement in a subset of participants with both PTSD and major depressive disorder (MDD). RESULTS: Results indicated that CPT was just as effective in treating "pure" PTSD and PTSD with comorbid MDD in terms of guilt. Clinical significance testing underscored that CPT was more effective in reducing certain trauma-related guilt cognitions than PE. LIMITATIONS: Findings cannot be generalized to men, and only one measure of guilt was used. CONCLUSIONS: The observed superiority of CPT over PE for treating certain guilt cognitions was not due to participant comorbidity. Further research is recommended to untangle the relationship between guilt, depression and differential response to treatment in PTSD following sexual assault trauma.

Regional cerebral glucose utilization rates in rats during asymptomatic period of exposure to 1, 2 and 3 atmospheres absolute of oxygen.

A previous study has shown an increase in regional cerebral metabolic rate for glucose prior to the onset of central nervous system oxygen toxicity in rats exposed to 5 atmospheres absolute of oxygen. The present study was designed to measure regional cerebral glucose utilization rates at pressures used for oxygen therapy and prolonged exposures during which rats are known to be asymptomatic. The regional metabolic rate for glucose in 26 brain structures and in gray and white matter of the thoracic and lumbar spinal cord was autoradiographically measured in awake unrestrained rats using the autoradiographic [14C]2-deoxyglucose technique. Femoral artery and vein cannulae were inserted 3 days before the experiment. Rats were divided into four groups of 15: (a) air control; (b) 6 h at 1 atmosphere absolute oxygen; (c) 4 h at 2 atmospheres oxygen; and (d) 2 h at 3 atmospheres oxygen. Statistically significant increases in glucose utilization (p less than 0.05) are seen only in lateral thalamus at 3 atmospheres oxygen, in superior olivary nucleus and inferior colliculus at 2 atmospheres oxygen and in superior olivary nucleus at 1 atmosphere oxygen. The combination of our previous data at 5 atmospheres oxygen and the present results at prolonged and safe exposures to lower pressures indicated that increased glucose utilization in some neuronal structures precedes the onset of the central nervous system manifestations of oxygen toxicity.

Recovery after the tsunami: timeline for rehabilitation.

In the aftermath of the Asian tsunami, there is potentially a large, traumatized population in need of psychosocial support, but determining which individuals require psychological intervention and knowing how and when to treat them may be the key to positive long-term outcomes. The early identification of people at high risk of developing subsequent psychiatric disorders from among those experiencing a transient stress reaction following trauma is often the initial step in the recovery process. Clinical instruments for screening and/or predicting those most at risk are available and require validating for cultural and linguistic sensitivity. Timely treatment is essential, since inappropriately targeted therapy can compromise recovery and may even exacerbate posttraumatic stress symptoms, particularly if treatment is initiated before grief reactions have subsided. Finally, appropriate treatment interventions, which incorporate cognitive-behavioral therapy and prolonged exposure, offer the best current therapeutic options for the treatment of posttraumatic stress disorder and associated comorbid conditions such as anxiety, depression, and grief. However, since most of the supportive data for the psychosocial consequences of trauma were obtained from small-scale studies of discrete trauma events in Western countries, it may not be possible to extrapolate these findings to a large-scale natural disaster in Asia, such as the Asian tsunami. More data are required to assist in the development of strategies for the effective management of the psychological consequences of trauma worldwide, with emphasis on creating mental health strategies that are culturally sensitive and valid for various trauma events and disaster scenarios.
