ØCD: protocol for the development and evaluation of a cognitive-behavioral prevention program for obsessive-compulsive disorder.

BACKGROUND: Obsessive-compulsive disorder (OCD) imposes significant burdens on individuals, families, and healthcare systems and the COVID-19 pandemic appears to have exacerbated OCD symptoms. Currently, there are no validated prevention programs for OCD, highlighting a critical gap in mental health services. This study aims to develop and validate the first ØCD prevention program, for at-risk adults, utilizing cognitive-behavioral therapy (CBT) and exposure response prevention (ERP) techniques. METHODS: A single-blind, randomized controlled trial comparing the ØCD prevention program to a waitlist control group will be conducted. Participants, at-risk adults (18-65 years) with subclinical OCD symptoms (OCI-R score ≥ 12), will be recruited for the study. The ØCD prevention program compresise of six online group sessions incorporating CBT and ERP techniques over three modules. The primary outcomes are OCD symptom severity (measured by the Obsessive-Compulsive Inventory- revised form; OCI-R), depression symptoms (measured by the Patient Health Questionnaire; PHQ-9), and anxiety symptoms (measured by the Generalised Anxiety Disorder 7-item; GAD-7). Secondary outcomes include OCD-related beliefs, experiential avoidance, resilience, quality of life, uncertainty intolerance, automatic thoughts, and distress. Outcome measures will be collected at baseline, at completion of the intervention, and one year later (follow-up). At follow-up, we will also analyze the OCD diagnostic incidence, using the Structured Clinical Interview for DSM-5. We will employ a multivariate analysis of variance (MANOVA) to explore whether significant differences exist between groups across dependent variables. To compare the OCD incidence levels from the pre-test to the follow-up we will use the chi-squared test. DISCUSION: The present study may contribute novel data on the efficacy of OCD prevention approaches, leading to the development of an evidence-based OCD prevention program that could alleviate individual and societal burdens associated with OCD. TRIAL REGISTRATION: This trial was approved by the University Ethical Review Authority (937/ 28.11.2023) at Babeș-Bolyai University and is registered on clinicaltrials.gov (ID: NCT06262464).

Improving Exposure Therapy: Rationale and Design of an International Consortium.

The Exposure Therapy Consortium (ETC) was established to advance the science and practice of exposure therapy. To encourage participation from researchers and clinicians, this article describes the organizational structure and activities of the ETC. Initial research working group experiences and a proof-of-principle study underscore the potential of team science and larger-scale collaborative research in this area. Clinical working groups have begun to identify opportunities to enhance access to helpful resources for implementing exposure therapy effectively. This article discusses directions for expanding the consortium's activities and its impact on a global scale.

Is repeated mistake-making an effective treatment strategy for perfectionism? Findings from a randomized controlled trial.

BACKGROUND AND OBJECTIVES: Perfectionism has been linked to self-criticism, procrastination, and psychological disorders. In a previous study, an exposure-based treatment for perfectionism (ETP), which included exposures targeted at concern over mistakes, showed positive outcomes when compared to waitlist. The aim of this study was to further investigate ETP by comparing it to a stress-management condition and assessing durability of treatment effects by conducting a one-month follow-up assessment. METHODS: Eighty-five individuals with elevated perfectionism were randomly assigned to receive ETP (n = 43) or a stress management treatment (n = 42). ETP involved repeatedly practicing mistake-making by completing computerized tasks engineered to cause individuals to make mistakes. The stress management condition included listening to videos and answering questions about healthy habits, such as diet, exercise, and sleep, as well as viewing calming videos. Participants completed eight treatment sessions as well as baseline, post-test, and one month follow-up self-report questionnaires. RESULTS: Contrary to predictions, compared to ETP, stress management led to significantly lower overall perfectionism, depression, generalized anxiety, and social anxiety at post and significantly lower depression, generalized anxiety, and social anxiety at follow-up. Further, individuals who completed ETP did not habituate to the exposure tasks, but distress increased from the first to the last treatment session. LIMITATIONS: The duration of treatment was relatively brief. CONCLUSIONS: This study highlights the importance of using active psychological control conditions in treatment outcome studies and the need to test various components of treatments for perfectionism to observe what may be effective or even potentially iatrogenic.

Implementation and Preliminary Outcomes of an Exposure-Based Summer Camp for Pediatric OCD and Anxiety.

Despite the high prevalence of anxiety disorders in children and adolescents and the existence of effective evidence-based treatments for them, access to psychological care remains a major public health concern. Summer camps may provide an effective treatment avenue for youth who might not otherwise have access to care. This study describes the design and implementation of Fear Facers, a semistructured, 5-day, daytime exposure-therapy-based summer camp designed for youth with a primary diagnosis of obsessive-compulsive disorder (OCD), social anxiety, separation anxiety, or a specific phobia. Preliminary data regarding feasibility and patient outcomes is also reported. Among 52 children and adolescents aged 7 to 16 who attended one of six camp sessions between 2018 and 2021, significant reductions in anxiety (d = 0.54) and OCD symptoms (d = 0.57) were observed from pre-camp to immediately post-camp. A subset of campers who were followed for an additional 3 months post-camp (n = 22) showed maintenance of treatment gains. Retention rates for the intervention were high. Our investigation provides further support for the use of a camp-based design for cognitive-behavioral approaches, and may provide a unique setting to maximize elements of inhibitory learning in exposures. We also discuss a number of elements regarding feasibility that need consideration for those hoping to develop similar interventions.

Refreshing, necessary exposure to the problem with exposure therapies for trauma: Commentary on Rubenstein et al. (2024).

In this invited commentary, I address what I see as the major contributions Rubenstein et al. (2024) have made to challenging the hegemony of exposure therapies for trauma-exposed persons. These include a thorough review of the history of the rise of exposure therapies, the identification of posttrauma responses as forms of anxiety disorders, and an extensive discussion of the neurobiology of the trauma response. Additionally, Rubenstein et al. expose the very high dropout rates in studies of exposure therapies and ways in which many traumatized people have not found them helpful. This article brings the so-called "gold standard" back to its rightful position as one possible, occasionally helpful way of assisting some, but not all, traumatized people.

[Intensive exposure treatment for obsessive compulsive disorder in old age.] / Intensieve exposure bij obsessieve-compulsieve stoornis op oudere leeftijd.

The absence of treatment studies for obsessive compulsive disorder (OCD) in older adults and the fact that OCD typically starts at a young age and often follows a chronic, fluctuating course quickly leads to therapeutic nihilism for older adults with OCD. In this case report, we present a 72-year-old man with OCD symptoms from the age of 35, who has only been treated with medication and psychotherapy for a recurrent depressive disorder. After a short, intensive exposure and response prevention treatment (four days in two weeks), the OCD symptoms and the depressive symptoms were fully in remission and all medications (venlafaxine, olanzapine, depakine) were discontinued. Treatment gains were maintained with persistent remission until 18 months follow up. This case report shows that a comorbid depressive disorder may lead to undertreatment of OCD. It also shows that long standing OCD can be successfully treated in older adults.

The effects of an intensive outpatient treatment for PTSD.

Introduction: Research has shown that combining different evidence-based PTSD treatments for patients with PTSD in an intensive inpatient format seems to be a promising approach to enhance efficiency and reduce generally high dropout rates.Objective: To assess the effectiveness of an intensive six-day outpatient trauma-focused treatment for patients with PTSD.Method: Data from 146 patients (89.7% female, mean age = 36.79, SD = 11.31) with PTSD due to multiple traumatization were included in the analyses. The treatment programme consisted of six days of treatment within two weeks, with two daily individual 90-minute trauma-focused sessions (prolonged exposure and eye movement desensitization and reprocessing), one hour of exercise, and one hour of psychoeducation. All participants experienced multiple traumas, and 85.6% reported one or more comorbid psychiatric disorders. PTSD symptoms and diagnoses were assessed with the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5), and self-reported symptoms were assessed with the PTSD Checklist for DSM-5 (PCL-5).Results: A significant decline in PTSD symptoms (CAPS-5 and PCL-5) from pretreatment to one-month follow-up (Cohen's d = 1.13 and 1.59) was observed and retained at six-month follow-up (Cohen's d = 1.47 and 1.63). After one month, 52.4% of the patients no longer met the diagnostic criteria for PTSD (CAPS-5). The Reliable Change Index (RCI) shows that 73.9% of patients showed improvement on the CAPS-5 and 77.61% on the PCL-5. Additionally, 21.77% (CAPS-5) and 20.0% (PCL-5) showed no change, while 4.84% (CAPS-5) and 2.96% (PCL-5) showed symptom worsening.Discussion: The results show that an intensive outpatient trauma treatment programme, including two evidence-based trauma-focused treatments, exercise, and psychoeducation, is effective for patients suffering from PTSD as a result of multiple traumatization. Subsequent research should focus on more controlled studies comparing the treatment programme with other intensive trauma treatments and less frequent routine treatment.

Intensive outpatient trauma treatment is effective in treating PTSD.Six days of combining prolonged exposure, EMDR, exercise and psycho-education seems feasible and effective in treating PTSD.73.9% of the patients show improvement on the CAPS-5 and 77.61% show improvement on the PCL-5, symptom worsening was there in 4,84, respectively 2.96%.

A Randomized Controlled Pilot Trial of Primary Care Treatment Integrating Motivation and Exposure Treatment (PC-TIME) in Veterans With PTSD and Harmful Alcohol Use.

Individuals with posttraumatic stress disorder (PTSD) often engage in harmful alcohol use. These co-occurring conditions are associated with negative health consequences and disability. PTSD and harmful drinking are typically experienced as closely related-thus treatments that target both simultaneously are preferred by patients. Many individuals with PTSD and harmful alcohol use receive primary care services but encounter treatment barriers in engaging in specialty mental health and substance use services. A pilot randomized controlled trial of a brief integrated treatment for PTSD and harmful drinking versus primary care treatment as usual (PC-TAU) took place in three U.S. Department of Veterans Affairs (VA) primary care clinics. The intervention (primary care treatment integrating motivation and exposure [PC-TIME]) combines motivational interviewing to reduce alcohol use and brief prolonged exposure for PTSD delivered over five brief sessions. Participants (N = 63) were veterans with PTSD and harmful drinking. Multilevel growth curve modeling examined changes in drinking (average number of drinks per drinking day and percentage of heavy drinking days) and self-reported PTSD severity at baseline, 8, 14, and 20 weeks. Participants reported high satisfaction with PC-TIME and 70% (n = 23) completed treatment. As hypothesized, a significantly steeper decrease in self-reported PTSD severity and heavy drinking was evident for participants randomized to PC-TIME compared with PC-TAU. Contrary to expectations, no significant posttreatment differences in PTSD diagnoses were observed. PC-TIME participants were less likely to exceed National Institute for Alcoholism and Alcohol Abuse (NIAAA) guidelines for harmful alcohol use posttreatment compared with PC-TAU participants. PC-TIME is a promising brief, primary care-based treatment for individuals with co-occurring PTSD and harmful alcohol use. A full-scale randomized clinical trial is needed to fully test its effectiveness.

Patient adherence as a predictor of acute and long-term outcomes in concentrated exposure treatment for difficult-to-treat obsessive-compulsive disorder.

BACKGROUND: Exposure and response prevention (ERP) is considered the first-line psychotherapy for obsessive-compulsive disorder (OCD). Substantial research supports the effectiveness of ERP, yet a notable portion of patients do not fully respond while others experience relapse. Understanding poor outcomes such as these necessitates further research. This study investigated the role of patient adherence to ERP tasks in concentrated exposure treatment (cET) in a sample who had previously not responded to treatment or relapsed. METHOD: The present study included 163 adults with difficult-to-treat OCD. All patients received cET delivered during four consecutive days. Patients' treatment adherence was assessed using the Patient EX/RP Adherence Scale (PEAS-P) after the second and third day of treatment. OCD severity was evaluated at post-treatment, 3-month follow-up, and 1-year follow-up by independent evaluators. RESULTS: PEAS-P scores during concentrated treatment were associated with OCD-severity at post-treatment, 3-month follow-up, and 1-year follow-up. Moreover, PEAS-P scores predicted 12-month OCD severity adjusting for relevant covariates. Adherence also predicted work- and social functioning at 1-year follow-up. CONCLUSIONS: These results indicate that ERP adherence during the brief period of cET robustly relates to improvement in OCD symptoms and functioning in both the short and long term. Assessing adherence might identify patients at risk of poor outcomes, while improving adherence may enhance ERP for treatment resistant patients.

A network analysis of mechanisms of change during exposures over the course of intensive OCD treatment.

Exposure and response prevention (ERP) is an evidence-based treatment for obsessive-compulsive disorder (OCD). Theories for how it works vary in their emphasis on active mechanisms of change. The current study aimed to clarify mechanisms of change in ERP for OCD using network analysis, comparing ERP networks at the start and end of intensive treatment (partial hospital and residential). In our sample of 182 patients, the most central node in both networks was engagement with exposure, which was consistently related to greater understanding of ERP rationale, higher willingness, and less ritualization, accounting for all other variables in the network. There were no significant differences in networks between the start and end of treatment. These results suggest that nonspecific parameters like facilitating engagement in exposures without ritualizing and providing a clear rationale to clients may be key to effective treatment. As such, it may be useful for clinicians to spend adequate time underscoring the need to eliminate rituals to fully engage in exposure tasks and explaining the rationale for ERP prior to doing exposures, regardless of theoretical orientation. Nonetheless, findings represent group-level statistics and more fine-grained idiographic analyses may reveal individual-level differences with respect to central mechanisms of change. Other limitations include demographic homogeneity of our sample.

Exploring the feasibility and acceptance of huddinge online prolonged exposure therapy (HOPE) for severe and complex PTSD.

Background: Trauma-focused cognitive behavioural therapy such as prolonged exposure is considered firsthand choice for treatment of posttraumatic stress disorder (PTSD) but is seldom available in regular care. Digital therapy is proposed to bridge this gap, but its effectiveness for severe and complex PTSD is uncertain. The primary objective of the current study was to examine the feasibility, acceptability, and preliminary effects of digital therapist-guided prolonged exposure (Huddinge Online Prolonged Exposure; HOPE).Method: Thirty participants with moderate to severe PTSD, with the majority self-reporting complex PTSD symptoms, received HOPE over a ten-week period. Eighty percent of participants had been diagnosed with other psychiatric comorbidity by a mental health professional. Primary outcome was the feasibility and acceptability of treatment. Participants were repeatedly assessed using clinician- and self-rated outcome measures at baseline, during the treatment period, post-treatment, and at 1-month and 6-month follow-ups to estimate preliminary treatment effects. The Clinician Administered PTSD Scale version 5 (CAPS-5), administered by independent assessors, evaluated PTSD symptom severity.Results: HOPE proved feasible and effective, delivering evidence-based treatment content in a psychiatric outpatient setting with reduced therapist time. The treatment was well-tolerated, with no severe adverse events and a 17% dropout rate. Sixty-four percent completed the exposure-based portion of the treatment, and overall satisfaction measured by the Client Satisfaction Questionnaire was moderate. Furthermore, significant reductions in PTSD symptoms as assessed with the CAPS-5 (Cohen's d = 1.30 [95% CI -1.79 to -0.82]) at the primary endpoint 1 month which were sustained at the 6-month follow up.Conclusion: Altogether, this study indicate feasibility of treating severe and complex PTSD through a digital PE intervention, thereby building upon and extending previous research findings. Large-scale controlled trials are needed to further validate the specific effect and long-term benefits of HOPE.Trial registration: ClinicalTrials.gov identifier: NCT05560854.

HOPE, a digital therapist-guided prolonged exposure programme, demonstrated feasibility and preliminary effects for severe and complex PTSD in a psychiatric outpatient setting, while requiring less therapist time.HOPE was well-tolerated by participants, with a relatively low dropout rate and average overall satisfaction.Significant reductions in PTSD symptoms were observed, and these benefits were sustained at the 6-month follow-up.

12-month follow-up of intensive outpatient treatment for PTSD combining prolonged exposure therapy, EMDR and physical activity.

BACKGROUND: Preliminary evidence shows promising treatment outcomes at short-term follow-up for intensive posttraumatic stress disorder (PTSD) treatment, but long-term follow-up studies are sparse. This study is a sequel to a previous pilot study and open trial, set out to investigate treatment outcomes at 12-month follow-up for outpatients completing an 8-day intensive treatment for PTSD. METHODS: All patients were diagnosed with PTSD and had multiple previous psychotherapy attempts (M = 3.1). Patients were assessed at pre-treatment, post-treatment, 3- and 12-month follow-up. Of 35 treated patients, 32 (91.4%) attended the long-term follow-up assessment. The treatment programme combined prolonged exposure therapy, eye movement desensitization and reprocessing, and physical activity. RESULTS: The effect sizes indicated large reductions in symptoms of PTSD, depression, anxiety, interpersonal problems, and well-being. Changes in functioning showed a small-medium effect. Results were stable across the follow-up period. The treatment response rates showed that 46-60% of patients achieved recovery with respect to PTSD symptoms, and that 44-48% no longer met diagnostic criteria for PTSD. CONCLUSIONS: Time-limited and concentrated outpatient treatment for PTSD can yield large and enduring positive outcomes. Controlled trials are needed to establish relative efficacy. TRIAL REGISTRATION: The study was registered in Current Research Information System In Norway (Cristin). Cristin-project-ID: 654,790. Date of registration: 18.03.2019.

An investigation of the role of estradiol in fear reduction during a single session of exposure therapy.

Research suggests that estradiol may moderate fear extinction. It is unclear whether these results generalize to exposure therapy. The aim of the current study was to determine whether estradiol moderates outcomes in exposure therapy among women with anxiety disorders. Participants were 35 women with a primary diagnosis of an anxiety disorder who participated in the study as part of routine care at an anxiety specialty clinic. Endogenous estradiol was assessed via saliva. They provided subjective distress ratings before (pre) and after (post) an exposure session, as well as after a brief delay (recall). Contrary to predictions, there were no significant differences in exposure outcomes between the high and low estradiol groups. However, among participants with primary obsessive-compulsive disorder (OCD), results were partially consistent with the hypotheses. Women with lower estradiol initially demonstrated more improvement in subjective distress from pre- to post-exposure, but after the delay, significantly greater distress (attenuated extinction recall). Results suggest that women with lower estradiol may respond less favorably to exposure therapy for OCD relative to women with higher estradiol. These findings await replication in larger samples with longer recall delays. Should replication occur, these results may inform the use of estradiol to augment exposure therapy.

Trauma-focused therapy retention among military sexual trauma survivors: relationship with veterans' sexual or gender minority identification.

Military servicemembers identifying as sexual and gender minorities (SGM) are at increased risk for military sexual trauma (MST) exposure and Post-traumatic Stress Disorder (PTSD). Although evidence-based treatments can reduce symptoms of PTSD, treatment attrition is concerning. Unfortunately, evaluations of such approaches with veterans identifying as SGM are currently restricted to case studies offering limited information regarding treatment completion. Both historic and current contextual factors related to military and mental health practices may uniquely influence minority veterans' treatment engagement in veteran healthcare settings. We explored associations between SGM identification and treatment of MST-focused therapy completion patterns (finishing the full protocol [FP] or receiving minimally adequate care [MAC; defined as attending eight or more sessions]). Veterans (N = 271, 12.5% SGM) enrolled in individual Prolonged Exposure or Cognitive Processing Therapies at a Midwestern veterans hospital system. Those identifying as SGM were more likely than non-identifying peers to complete FP treatment and, even when attrition occurred, they were retained longer. For MAC, the SGM group was as likely as non-SGM peers to be retained. This research suggests SGM veterans represent a notable minority of those seeking treatment in association with MST and do not appear at greater risk for discontinuation from trauma-focused treatment.

Written exposure therapy for veterans with co-occurring substance use disorders and PTSD: Study design of a randomized clinical trial.

There are high rates of posttraumatic stress disorder (PTSD) among treatment-seeking veterans with substance use disorders (SUD). While addiction programs traditionally do not address PTSD, there is evidence that trauma treatments for individuals with this comorbidity have improved PTSD and SUD outcomes. Written exposure therapy (WET), a five-session evidence-based psychotherapy (EBP) for PTSD, has high patient satisfaction, and lower dropout compared to other EBPs for PTSD. WET may be ideally suited for clinical settings that may not have the trauma expertise found in PTSD specialty clinics, given it requires less training time, treatment sessions, preparation time, and therapist involvement than existing EBPs, and no homework assignments. This paper describes the design, methodology, and protocol of a randomized clinical trial to evaluate whether treatment as usual (TAU) plus WET (n = 51) is superior to TAU plus a neutral topic writing condition (n = 51) on both PTSD and addiction outcomes for veterans in SUD treatment. The primary hypothesis is that participants assigned to TAU+WET, compared to those in TAU+ neutral topic writing, will report reduced symptoms of PTSD. The secondary hypothesis is that veterans receiving WET will have greater decreases in number of days of substance use compared to TAU+ neutral topic controls at follow-up. Assessments will take place at baseline, post-treatment, 8-week, and 12-week follow-up. Exploratory aims will examine the association between heart rate variability and treatment outcomes. If results prove promising, they will support WET as an effective brief, easy to disseminate, adjunct to current SUD treatment for veterans with comorbid PTSD.

Differential relations between breathing retraining, in vivo exposure, and imaginal exposure homework completion and treatment outcomes in veterans receiving prolonged exposure for PTSD.

OBJECTIVES: Limited research exists that outlines the predictive relevance of the treatment components of prolonged exposure (PE) for post-traumatic stress disorder (PTSD) on PTSD and depression symptom outcomes. The goal of the present study was to investigate relations between participant completion of breathing retraining, in vivo exposure, and imaginal exposure exercises and symptom outcomes. METHODS: A total of 58 participants completed a trial of PE as part of a larger trial on peer involvement and treatment adherence. Diagnostic and self-report measures were completed throughout treatment. Participants also recorded weekly completion of breathing retraining, in vivo exposure, and imaginal exposure exercises. Pearson correlations and hierarchical regression analyses were used to investigate relations between average weekly treatment component completion and treatment outcomes, controlling for relevant variables. RESULTS: Although breathing retraining and in vivo exposures were associated with PTSD outcomes in the correlational findings, use of breathing retraining, in vivo exposures, and imaginal exposures were not reliably associated with PTSD symptom outcomes when controlling for other variables in the regression analysis. However, when investigating changes in comorbid symptoms of depression, greater use of breathing retraining was associated with decreased symptoms of depression at posttreatment. CONCLUSIONS: Present findings demonstrate the differential relations between participation in various PE treatment components and posttreatment symptom outcomes. The importance of breathing retraining in addressing comorbid depressive symptoms is discussed, with emphasis on potentially increasing relaxation and positive activities more broadly to encourage further treatment benefits.

Impact of three variants of prolonged exposure therapy on comorbid diagnoses in patients with childhood abuse-related PTSD.

Recent studies indicated that Prolonged Exposure (PE) is safe and effective for posttraumatic stress disorder (PTSD). It is unclear whether PE also leads to a reduction in comorbid diagnoses. Data from a large randomized controlled trial (N = 149) on the effects of three variants of PE for PTSD were used. We examined the treatment effects on co-morbid diagnoses of depressive, anxiety, obsessive compulsive, substance abuse, psychotic, eating and personality disorders in a sample of patients with PTSD related to childhood abuse. Outcomes were assessed with clinical interviews at baseline, post-treatment and at 6- and 12-month follow-up. All variants of PE led to a decrease from baseline to post-treatment in diagnoses of depressive, anxiety, substance use and personality disorders. Improvements were sustained during follow-up. We found an additional decrease in the number of patients that fulfilled the diagnostic criteria of a depressive disorder between 6- and 12-month follow-up. No significant changes were observed for the presence of OCD, psychotic and eating disorders. Findings suggest that it is effective to treat PTSD related to childhood abuse with trauma-focused treatments since our 14-to-16 weeks PE for PTSD resulted in reductions in comorbid diagnoses of depressive, anxiety, substance use and personality disorders.

HLD-DDoSDN: High and low-rates dataset-based DDoS attacks against SDN.

Software Defined Network (SDN) has alleviated traditional network limitations but faces a significant challenge due to the risk of Distributed Denial of Service (DDoS) attacks against an SDN controller, with current detection methods lacking evaluation on unrealistic SDN datasets and standard DDoS attacks (i.e., high-rate DDoS attack). Therefore, a realistic dataset called HLD-DDoSDN is introduced, encompassing prevalent DDoS attacks specifically aimed at an SDN controller, such as User Internet Control Message Protocol (ICMP), Transmission Control Protocol (TCP), and User Datagram Protocol (UDP). This SDN dataset also incorporates diverse levels of traffic fluctuations, representing different traffic variation rates (i.e., high and low rates) in DDoS attacks. It is qualitatively compared to existing SDN datasets and quantitatively evaluated across all eight scenarios to ensure its superiority. Furthermore, it fulfils the requirements of a benchmark dataset in terms of size, variety of attacks and scenarios, with significant features that highly contribute to detecting realistic SDN attacks. The features of HLD-DDoSDN are evaluated using a Deep Multilayer Perception (D-MLP) based detection approach. Experimental findings indicate that the employed features exhibit high performance in the detection accuracy, recall, and precision of detecting high and low-rate DDoS flooding attacks.

Design of a hybrid implementation effectiveness cluster randomized controlled trial of delivering written exposure therapy for PTSD in underserved primary care settings.

INTRODUCTION: Posttraumatic stress disorder (PTSD) results in substantial costs to society. Prevalence of PTSD among adults is high, especially among those presenting to primary care settings. Evidence-based psychotherapies (EBPs) for PTSD are available but dissemination and implementation within primary care settings is challenging. Building Experience for Treating Trauma and Enhancing Resilience (BETTER) examines the effectiveness of integrating Written Exposure Therapy (WET) within primary care collaborative care management (CoCM). WET is a brief exposure-based treatment that has the potential to address many challenges of delivering PTSD EBPs within primary care settings. METHODS: The study is a hybrid implementation effectiveness cluster-randomized controlled trial in which 12 Federally Qualified Health Centers (FQHCs) will be randomized to either CoCM plus WET (CoCM+WET) or CoCM only with 60 patients within each FQHC. The primary aim is to evaluate the effectiveness of CoCM+WET to improve PTSD and depression symptom severity. Secondary treatment outcomes are mental and physical health functioning. The second study aim is to examine implementation of WET within FQHCs using FQHC process data and staff interviews pre- and post-intervention. Exploratory aims are to examine potential moderators and mediators of the intervention. Assessments occur at baseline, and 3- and 12-month follow-up. CONCLUSION: The study has the potential to impact practice and improve clinical and public health outcomes. By establishing the effectiveness and feasibility of delivering a brief trauma-focused EBP embedded within CoCM in primary care, the study aims to improve PTSD outcomes for underserved patients.

Effectiveness of prolonged exposure (PE) after implementation at a crime victim support centre.

Background: Recent practice guidelines strongly recommend evidence-based psychotherapies (EBPs) as the first-line treatment for post-traumatic stress disorder (PTSD). However, previous studies found barriers to the implementation of EBPs and a relatively high dropout rate in clinical settings. After proving the efficacy of prolonged exposure (PE) in Japan [Asukai, N., Saito, A., Tsuruta, N., Kishimoto, J., & Nishikawa, T. (2010). Efficacy of exposure therapy for Japanese patients with posttraumatic stress disorder due to mixed traumatic events: A randomized controlled study. Journal of Traumatic Stress, 23(6), 744-750. https://doi.org/10.1002/jts.20589], we began implementing PE in a real-world clinical setting at the Victim Support Center of Tokyo (VSCT).Objective: We aimed to investigate the effectiveness and benefit of PE for crime-induced PTSD among VSCT clients and what causes dropout from treatment.Method: Of 311 adult clients who received counselling from clinical psychologists at VSCT due to violent or physical crime victimization from April 2008 through December 2019, 100 individuals received PE and participated in this study. Their PTSD symptoms were evaluated before and after treatment using the Impact of Event Scale-Revised and the Clinician-Administered PTSD Scale for DSM-IV.Results: A total of 93 participants completed PE and seven dropped out after six sessions or less. The completers group improved in PTSD symptoms with significant score differences between pre- and post-treatment in IES-R and CAPS-IV. Participants' symptoms did not exacerbate after treatment. Forty of 49 completers who left their workplace or college/school after victimization returned to work or study shortly after treatment. Compared to the completers, all dropout participants were women and younger. The majority were rape survivors, with significantly shorter intervals between victimization and treatment. The reasons for dropout were difficulty scheduling treatment between work/study schedules and manifestation of bipolar disorder or physical illness.Conclusions: PE can be implemented with significant effectiveness and a low dropout rate in a real-world clinical setting if advantages in the system and policies, local organizational context, fidelity support and patient engagement are fortified.

We conducted prolonged exposure (PE) with a low dropout rate for crime-induced PTSD in a non-Western real-world practice setting.Patient outcomes and low dropout rate of PE for PTSD in this study may be due to advantages in the following areas: system and policies, local organizational context, fidelity support and patient engagement.When introducing PE for PTSD, it is important to confirm that patients can be reasonably engaged with PE, and to carefully assess the status of other psychiatric and physical illnesses.
