Abstract
Empirically supported treatments for posttraumatic stress disorder (PTSD) exist, but research suggests these therapies are less effective, acceptable, and feasible to deliver to active duty service members (SMs) compared to civilians. Stellate ganglion block (SGB) procedure, in which a local anesthetic is injected around the cervical sympathetic chain or stellate ganglion to temporarily inhibit sympathetic nervous activity, is gaining popularity as an alternative PTSD treatment in military settings. However, it is unknown whether certain PTSD symptoms are more responsive to SGB than others. The current study involved a secondary analysis of data collected from a previous randomized controlled trial of SGB compared to sham (normal saline) injection (N = 113 SMs). PTSD symptoms were assessed via clinical interview and self-report at baseline and 8 weeks post-SGB or sham. Logistic regression analyses showed that the marked alterations in arousal and reactivity PTSD symptom cluster demonstrated the greatest symptom severity reductions after SGB, relative to sham. The reexperiencing cluster also showed pronounced response to SGB in clinician-rated but not self-reported outcomes. Post-hoc item-level analyses suggested that arousal and reactivity cluster findings were driven by reductions in hypervigilance, concentration difficulties, and sleep disturbance, whereas clinician-rated reexperiencing cluster findings were driven by reductions in physiological reactions to trauma cues, emotional reactions to trauma cues, and intrusions. Our findings align with a burgeoning literature positioning SGB as a potential novel or adjunctive PTSD treatment. Results could guide future hypothesis-driven research on mediators of therapeutic change during SGB for PTSD symptoms in SMs.

Heart rate reactivity during trauma recall as a predictor of treatment outcome in cognitive processing therapy for PTSD. Behav Res Ther 2024; 176:104519. [PMID: 38503205 PMCID: PMC10999335 DOI: 10.1016/j.brat.2024.104519] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 03/05/2024] [Accepted: 03/08/2024] [Indexed: 03/21/2024]
Abstract
Emotional engagement when recollecting a trauma memory is considered a key element of effective trauma-focused therapy. Research has shown that reduced physiological reactivity during trauma recall is associated with worse treatment outcomes for posttraumatic stress disorder (PTSD), but this has yet to be examined in a cognitively oriented treatment. This study examined whether pretreatment heart rate (HR) reactivity during trauma recall predicts PTSD symptom improvement and treatment dropout during Cognitive Processing Therapy (CPT) for PTSD. Participants were 142 women with PTSD secondary to interpersonal violence enrolled in one of two clinicals trials. HR reactivity reflected the mean increase in HR after listening to two 30-s scripts of the trauma memory prior to treatment. Linear mixed-effects models showed the effect of HR reactivity on change in total PTSD symptoms was not significant, but lower HR reactivity predicted less improvement in reexperiencing and avoidance and was associated with increased dropout. Findings suggest pretreatment physiological reactivity to the trauma memory may be a prognostic indicator of some elements of treatment response in CPT. Results tentatively support the importance of emotional activation during trauma recall in cognitive treatment of PTSD, though more research is needed to clarify how low HR reactivity impacts treatment.

Abstract
BACKGROUND The long-term mental and physical health implications of childhood interpersonal trauma on adult survivors is immense, however, there is a lack of available trauma-focused treatment services that are widely accessible. This study, utilizing a user-centered design process, sought feedback on the initial design and development of a novel, self-paced psychoeducation and skills-based treatment intervention for this population. AIMS To explore the views and perspectives of adult survivors of childhood interpersonal trauma on the first two modules of an asynchronous trauma-focused treatment program. METHODS Fourteen participants from our outpatient hospital service who completed the modules consented to provide feedback on their user experience. A thematic analysis of the three focus groups was conducted. RESULTS Four major themes emerged from the focus groups: (1) technology utilization, (2) module content, (3) asynchronous delivery, and (4) opportunity for interactivity. Participants noted the convenience of the platform and the use of multimedia content to increase engagement and did not find the modules to be emotionally overwhelming. CONCLUSIONS Our research findings suggest that an asynchronous virtual intervention for childhood interpersonal trauma survivors may be a safe and acceptable way to provide a stabilization-focused intervention on a wider scale.

Mindful self-compassion for veteran women with a history of military sexual trauma: feasibility, acceptability, potential benefits, and considerations. Eur J Psychotraumatol 2024; 15:2301205. [PMID: 38349003 PMCID: PMC10866049 DOI: 10.1080/20008066.2023.2301205] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/02/2023] [Accepted: 12/08/2023] [Indexed: 02/15/2024] Open
Abstract
Background: Military sexual trauma (MST) is reported by up to 74% of women veterans in the United States and is a driver of poor behavioural and physical health. Self-compassion is a transdiagnostic, protective factor linked with improved posttraumatic stress disorder (PTSD), depression, and health behaviours. Thus, Mindful Self-Compassion training (MSC) may help ameliorate MST-related impacts. However, MSC can also temporarily increase distress (i.e. backdraft). Delivering it with elective trauma-informed yoga (TIY), which regulates acute distress, may help address this issue.Objective: This VA quality improvement project examined feasibility, acceptability, and reported benefits and challenges of a manualized 8-week MSC including within non-randomized subgroups: MSC (n = 4) and MSC+ elective TIY classes (MSC+; n = 4).Methods: Nine women veterans with a history of MST at a Vet Center in the Northeastern U.S.A. enrolled; eight completed, excluding one MSC+ participant. Measures included attrition (n = 9), attendance (n = 8), weekly (n = 8) and posttreatment acceptability (n = 6), validated symptom severity assessments (n = 7), and an exit interview (n = 8).Results: Among completers, MSC attendance was excellent (89%) and higher among in MSC+ vs. MSC (94% vs. 84% sessions completed). On average across the two groups, depressive and PTSD symptom severity decreased by 21% and 30%, respectively. In exit interviews, participants across groups described improved coping with distress and psychiatric symptoms, reduced stress, and improved self-care and health behaviours. Although women in both groups reported backdraft during the programme, MSC+ also reported healthier coping and improved emotional processing.Conclusion: The results of this programme evaluation infer MSC may be feasible, acceptable, and beneficial for women survivors of MST in one Vet Center in the Northeastern USA. Further, temporary elevations in MSC-related distress may be ameliorated with adjunctive TIY. Given requests of women veterans in the USA. for additional complementary and integrative health treatment options, formal research on these approaches is warranted.

Abstract
OBJECTIVE Greater duration of negative trauma-related beliefs may inhibit improvements in these cognitions during posttraumatic stress disorder (PTSD) treatment. The goal of the current study was to examine the impact of time since trauma on change in negative trauma-related beliefs during PTSD treatment. METHOD A sample of 126 adults diagnosed with PTSD were randomized to Cognitive Processing Therapy (CPT) or Written Exposure Therapy (WET) and completed the Posttraumatic Cognitions Inventory (PTCI) at pretreatment and 6, 12, 24, 36, and 60 weeks following the first treatment session. RESULTS Consistent with past findings, negative cognitions related to the self, others, and self-blame decreased during and after trauma-focused therapy. Greater time since the trauma was associated with less improvement in negative trauma-related beliefs about the world and less early improvement in negative trauma-related beliefs about the self and self-blame. The effect of time since trauma on reduction in negative trauma-related beliefs about the world was stronger among participants randomized to CPT. CONCLUSIONS These results indicate that trauma-focused therapies become less potent in reducing trauma-related beliefs as time progresses since trauma exposure, particularly in CPT, for beliefs about the world. Results indicate PTSD treatment should be provided in closer proximity to trauma exposure before negative trauma-related beliefs become inflexible.

Abstract
Prolonged exposure (PE) and cognitive processing therapy (CPT) for posttraumatic stress disorder (PTSD) are effective, but some patients do not respond adequately, and dropout rates are high. Patients' beliefs about treatment and perceptions of treatment components influence treatment outcomes and may be amenable to change through intervention. The present study sought to identify beliefs and reactions to PE and CPT that differentiated completers who screened negative for a PTSD diagnosis after treatment (PTSD-), completers who screened positive for a PTSD diagnosis after treatment (PTSD+), and discontinuers who attended six or fewer sessions. Thematic analysis was used to identify themes in qualitative data collected via retrospective semistructured interviews with 51 completers (19 PTSD- after treatment, 32 PTSD+ after treatment) and 66 discontinuers of PE/CPT. Participants were demographically diverse veterans across service eras. Treatment-related beliefs and reactions differentiating these groups included perceived helpfulness of treatment, self-efficacy in engaging in treatment, anticipatory anxiety and concerns, interpretations of ongoing symptoms, and perceived consequences of treatment on functioning. Further, some patterns seemed to differ in early treatment sessions compared to during the active components of treatment. Findings point to potentially malleable targets that could be intervened upon to improve trauma-focused treatment outcomes. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Abstract
BACKGROUND AND OBJECTIVES Evidence indicates that positive memory processes play a role in the etiology and maintenance of posttraumatic stress symptoms (PTSS) and related posttrauma health indicators. To extend this research, the current pilot study examined if repeated retrieval of positive vs. neutral memories was associated with (1) less PTSS and depression severity; and (2) improved affect and cognitions (fewer posttrauma cognitions, more positively-valenced affect, less negatively-valenced affect, less negative affect interference, less anhedonia, retrieval of more positive specific memories, retrieval of fewer negative specific memories). METHODS Twenty-five trauma-exposed participants were randomly assigned to a positive or neutral memory task condition. They participated in four weekly experimental sessions facilitated by an experimenter virtually; each consecutive session was separated by 6-8 days. We conducted mixed between-within subjects ANOVAs to examine study hypotheses. RESULTS No interaction effects were significant. There were significant main effects of time on PTSS and depression severity, posttrauma cognitions, positively-valenced and negatively-valenced affect, and negative affect interference. LIMITATIONS We used self-report measures, small and non-clinical sample with limited demographic diversity, and virtual format; did not record memory narratives; and did not have a trauma memory condition. CONCLUSIONS Based on pilot data, our findings suggest that individuals who retrieve positive or neutral memories repeatedly may report less PTSS and depression severity, fewer posttrauma cognitions, and improved affect. Results provide an impetus to examine impacts of and mechanisms underlying memory interventions (beyond a sole focus on negatively-valenced memories) in trauma work.

Abstract
Dropout rates for treatments for adult posttraumatic stress disorder (PTSD) are high. Process research can reveal client factors during treatment that predict dropout. An observational coding system was used to code client processes in audio-recorded early sessions of cognitive processing therapy (CPT), a gold-standard treatment for PTSD. Data are from a randomized controlled noninferiority trial of CPT and written exposure therapy (WET), with higher rates of dropout in CPT than WET (39.7% vs. 6.4%). Participants in this study were 53 treatment-seeking adults with PTSD who were in the CPT arm of the trial and completed the CAPS-5 at pretreatment and at least one session. Of these, 15 (28.3%) dropped out of CPT early (completing ≤9 sessions) and 38 (71.7%) completed treatment. Sessions were coded with an observational coding system on a four-point scale (0 = absent to 3 = high) for maladaptive trauma-related responses (overgeneralized beliefs, ruminative processing, avoidance), affective engagement (negative emotions, physiological distress), and adaptive processing (cognitive emotional processing). Binary logistic regressions showed that more physiological distress and cognitive emotional processing predicted lower dropout, whereas more avoidance predicted higher dropout. Negative emotion, ruminative processing, and overgeneralization were not significant predictors. These findings highlight potential early indicators of treatment engagement that could be targeted to reduce dropout and perhaps facilitate further therapeutic change.

Abstract
Prolonged exposure (PE) is an empirically supported treatment for posttraumatic stress disorder (PTSD). The current study examined multiple facilitators and indicators of emotional processing to identify key predictors of outcome in PE using observational coding methods. Participants were 42 adults with PTSD who received PE. Video recordings of sessions were coded to capture negative emotion activation, negative and positive trauma-related cognitions, and cognitive rigidity. Two variables emerged as predictors of PTSD symptom improvement assessed via self-report, but not clinical interview: a greater decrease in negative trauma-related cognitions and lower average cognitive rigidity. Peak emotion activation, reductions in negative emotions, and increases in positive cognitions did not predict PTSD improvement (self-report or clinical interview). Findings contribute to growing evidence highlighting the importance of cognitive change as part of emotional processing and as a key ingredient of PE, beyond activation and reduction in negative emotions. Implications for evaluating emotional processing theory and for clinical practice are discussed.

Abstract
Processing of Positive Memories Technique (PPMT) was proposed as a novel intervention for posttraumatic stress disorder (PTSD). PPMT comprises of 5 sessions focused on identifying and processing positive memories. As an open label pilot study, we explored PPMT's effects on PTSD severity, depression severity, affect and cognitive processes, and therapeutic alliance. A sample of 12 trauma-exposed participants seeking services at a University Psychology Clinic participated in 5 PPMT sessions (Mage=29.25 years; 58.30% women). We used the reliable change indices and clinically significant change score approach. The following number of participants showed statistically reliable changes: 9 participants for PTSD severity (8 recovered/improved); 6 participants for depression severity (5 improved); 5 participants for positive affect levels (2 recovered/improved); 9 participants for negative affect levels (8 recovered); 9 participants for posttrauma cognitions (7 recovered/improved); 5 participants for positive emotion dysregulation (4 recovered); 11 participants for number of retrieved positive memories (3 recovered); and 5 participants for therapeutic alliance (4 recovered). PPMT may impact certain posttrauma targets more effectively (PTSD, depression, negative affect, posttrauma cognitions). PPMT may be more helpful in improving regulation rather than levels of positive affect. PPMT, if supported in further investigations, may add to the clinician tool-box of PTSD interventions.

Abstract
Cognitive processing therapy (CPT) is an evidence-based treatment for posttraumatic stress disorder (PTSD), but little is known about in-session process variables that predict symptom reduction and treatment completion during CPT. Examining potentially malleable factors that may promote or impede recovery can inform care delivery and enhance outcomes. The current study used observational ratings of CPT session recordings to examine in-session patient and therapist factors in cognitive, affective, and interpersonal domains to identify their relative contributions to predicting symptom outcomes and treatment completion. Participants were 70 adult survivors of interpersonal violence who received CPT. Predictors of better posttreatment PTSD outcomes included less patient fear, β = .32, and less patient avoidance of engaging with the therapist, β = .35. When using the last available PTSD score, less fear, β = .23, and avoidance, β = .28, continued to predict better outcomes, and more patient cognitive flexibility emerged as a stronger predictor of outcome, β = -.33. Predictors of a higher likelihood of treatment completion included more therapist use of Socratic dialogue, OR = 6.75, and less therapist encouragement of patient affect, OR = 0.11. Patient sadness and anger and therapist expression of empathy did not predict symptom outcomes or treatment completion versus dropout. The results highlight the importance of patients' cognitions, emotions, and engagement with their therapist in CPT as well as the role of therapist behaviors in patient completion of treatment.

A Pilot Study of a Three-Session Heart Rate Variability Biofeedback Intervention for Veterans with Posttraumatic Stress Disorder. Appl Psychophysiol Biofeedback 2023; 48:51-65. [PMID: 36331685 DOI: 10.1007/s10484-022-09565-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 10/18/2022] [Indexed: 11/06/2022]
Abstract
Many veterans do not complete traditional trauma treatments; others may continue to struggle with posttraumatic stress disorder (PTSD) even after completing a full course of therapy (Blasé et al., in Int J Environ Res Public Health 18(7):Article 3329, https://doi.org/10.3390/ijerph18073329 , 2016). Heart rate variability (HRV) biofeedback (HRVB) is a non-invasive, non-pharmacological, breathing-based cardiorespiratory training technique that can reduce trauma symptoms and improve HRV parameters. Prior studies have demonstrated HRVB is well-tolerated by veterans with PTSD symptoms (Tan et al., in Appl Psychophysiol Biofeedback 36(1):27-35, 10.1007/s10484-010-9141-y, 2011; Schuman and Killian, in Appl Psychophysiol Biofeedback 44(1):9-20, https://doi.org/10.1007/s10484-018-9415-3 , 2019). This randomized wait-list controlled pilot study tested a short mobile app-adapted HRVB intervention in combination with treatment as usual for veterans with military-related PTSD to determine if further investigation was warranted. We assessed veterans' military-related PTSD symptoms, depression symptoms, and HRV time and frequency domain measures at baseline, after three clinical sessions, and one month later. This study combined clinical training and home biofeedback with a smartphone app and sensor to reinforce training and validate adherence. In the intervention group, depression and SDNN significantly improved, and we observed marginally significant improvements for PTSD Cluster B (intrusion) symptoms, whereas no significant improvements were observed in the control group. In addition, the brief protocol was acceptable to veterans with PTSD with over 83% of participants completing the study. However, adherence to home practice was low. Findings suggest brief HRVB interventions can decrease comorbid depression and improve overall autonomic function in veterans with PTSD; however, additional research on home biofeedback is necessary to determine the best strategies to increase adherence and which veterans would benefit from brief HRVB interventions.

Abstract
Written exposure therapy (WET) is a brief, five-session treatment for posttraumatic stress disorder (PTSD) that aims to improve access to care. WET has been demonstrated to be an efficacious PTSD treatment with lower rates of dropout and noninferior PTSD symptom outcome compared to cognitive processing therapy (CPT), a 12-session, gold-standard treatment. To identify predictors of treatment outcome in both WET and CPT, the current study examined the content of participants' written narratives. Participants were 123 adults with PTSD who were randomly assigned to receive WET (n = 61) or CPT (n = 62). The Change and Growth Experiences Scale (CHANGE) coding system was used to code all available narratives in both treatment conditions for variables hypothesized to be relevant to therapeutic change. Linear regression analyses revealed that in WET, higher average levels of accommodated (healthy, balanced) beliefs and an increase in accommodated beliefs from the first to the final impact statement predicted better PTSD symptom outcome at 12 weeks postrandomization. In CPT, higher average levels of overgeneralized and accommodated beliefs and lower levels of avoidance expressed in the narratives predicted better PTSD outcome. There were no significant predictors of outcome in analyses of change from the first to final impact statement in CPT. These findings add to research identifying predictors of change in WET and CPT by highlighting the importance of low avoidance in CPT and of trauma-related cognitions in both CPT and WET, even though WET is a brief written intervention that does not explicitly target cognitive change.

Abstract
With the establishment of empirically validated treatments for posttraumatic stress disorder (PTSD), concerns remain regarding the effectiveness of such treatments in real-world clinical settings. Specifically, premature termination and treatment response limit the effectiveness of these interventions. The current study investigated factors potentially related to premature termination and treatment response in Cognitive Processing Therapy with Account (CPT-A). Participants in this study included 42 women (Mage = 30.70 SDage = 9.40) with PTSD from exposure to interpersonal trauma. Demographic characteristics, pre-treatment symptoms of PTSD and depression, and transdiagnostic factors were examined as predictors of attrition and treatment response. Hierarchical regression and logistic regression models were analyzed to test the variance explained and predictive value of these factors. The present study revealed that age was a significant factor related to dropout from CPT-A whereas baseline PTSD symptom severity was significantly related to treatment response. Results of this study suggest the importance of the interrelationships among pre-treatment predictors as well as the consideration of attrition and treatment response as distinct metrics of treatment outcome. Further, these results inform the application of CPT-A for PTSD in survivors of interpersonal trauma, as consideration of the identified predictors of dropout and non-response at intake may contribute to treatment retention and response.

Abstract
Trauma-focused cognitive-behavioral therapy (TF-CBT), broadly, is one of the leading evidence-based treatments for youth with posttraumatic stress disorder (PTSD). Generally, few culturally adapted TF-CBT interventions have been examined among war trauma-affected populations in low- and middle-income countries. Using a randomized clinical trial design, a total of 48 war trauma-exposed women in Iraq, Mage (SD) = 32.91 (5.33), with PTSD were randomly assigned to either TF-CBT or wait-list control (WLC) conditions. The intervention group received 12 individual weekly sessions of a culturally adapted TF-CBT intervention. Significant reductions in PTSD symptom severity were reported by women in the TF-CBT condition from pre- to posttreatment. Women in the TF-CBT condition reported significantly greater reductions in PTSD symptoms compared to WLC at 1-month follow-up. Additionally, levels of depression, anxiety, stress, and use of maladaptive emotion regulation strategies were significantly lower in the TF-CBT condition at posttreatment and 1-month follow-up, compared to the WLC condition. Women in the TF-CBT condition also reported significant improvements in various domains of quality of life at posttreatment and 1-month follow-up. This clinical trial provides preliminary cross-cultural support for the feasibility and efficacy of TF-CBT for the treatment of PTSD symptoms among women in non-Western cultures. Future directions and study limitations are discussed.

Abstract
Question Do cognitive behavioral therapies for posttraumatic headache and posttraumatic stress disorder (PTSD) symptoms improve headache-related disability in veterans compared with treatment per usual? Findings A randomized clinical trial of 193 post-9/11 combat veterans with posttraumatic headache and PTSD symptoms found headache disability was significantly improved with cognitive behavioral therapy for headaches compared with treatment per usual. Though participants randomly assigned to cognitive processing therapy reported significantly greater improvement in PTSD symptom severity compared with treatment per usual, there was no significant effect of cognitive processing therapy on headache disability. Meaning Cognitive behavioral therapies are efficacious treatments for veterans with comorbid posttraumatic headache and PTSD symptoms. Importance Posttraumatic headache is the most disabling complication of mild traumatic brain injury. Posttraumatic stress disorder (PTSD) symptoms are often comorbid with posttraumatic headache, and there are no established treatments for this comorbidity. Objective To compare cognitive behavioral therapies (CBTs) for headache and PTSD with treatment per usual (TPU) for posttraumatic headache attributable to mild traumatic brain injury. Design, Setting, and Participants This was a single-site, 3–parallel group, randomized clinical trial with outcomes at posttreatment, 3-month follow-up, and 6-month follow-up. Participants were enrolled from May 1, 2015, through May 30, 2019; data collection ended on October 10, 2019. Post-9/11 US combat veterans from multiple trauma centers were included in the study. Veterans had comorbid posttraumatic headache and PTSD symptoms. Data were analyzed from January 20, 2020, to February 2, 2022. Interventions Patients were randomly assigned to 8 sessions of CBT for headache, 12 sessions of cognitive processing therapy for PTSD, or treatment per usual for headache. Main Outcomes and Measures Co–primary outcomes were headache-related disability on the 6-Item Headache Impact Test (HIT-6) and PTSD symptom severity on the PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) (PCL-5) assessed from treatment completion to 6 months posttreatment. Results A total of 193 post-9/11 combat veterans (mean [SD] age, 39.7 [8.4] years; 167 male veterans [87%]) were included in the study and reported severe baseline headache-related disability (mean [SD] HIT-6 score, 65.8 [5.6] points) and severe PTSD symptoms (mean [SD] PCL-5 score, 48.4 [14.2] points). For the HIT-6, compared with usual care, patients receiving CBT for headache reported −3.4 (95% CI, −5.4 to −1.4; P < .01) points lower, and patients receiving cognitive processing therapy reported −1.4 (95% CI, −3.7 to 0.8; P = .21) points lower across aggregated posttreatment measurements. For the PCL-5, compared with usual care, patients receiving CBT for headache reported −6.5 (95% CI, −12.7 to −0.3; P = .04) points lower, and patients receiving cognitive processing therapy reported −8.9 (95% CI, −15.9 to −1.9; P = .01) points lower across aggregated posttreatment measurements. Adverse events were minimal and similar across treatment groups. Conclusions and Relevance This randomized clinical trial demonstrated that CBT for headache was efficacious for disability associated with posttraumatic headache in veterans and provided clinically significant improvement in PTSD symptom severity. Cognitive processing therapy was efficacious for PTSD symptoms but not for headache disability. Trial Registration ClinicalTrials.gov Identifier: NCT02419131

Abstract
The advent of the intelligence age has injected new elements into the development of literature. The synergic modification of Anglo-American (AAL) traumatic narrative (TN) literature by artificial intelligence (AI) technology and interactive design (ID) psychology will produce new possibilities in literary creation. First, by studying natural language processing (NLP) technology, this study proposes a modification language model (LM) based on the double-layered recurrent neural network (RNN) algorithm and constructs an intelligent language modification system based on the improved LM model. The results show that the performance of the proposed model is excellent; only about 30% of the respondents like AAL literature; the lack of common cultural background, appreciation difficulties, and language barriers have become the main reasons for the decline of reading willingness of AAL literature. Finally, AI technology and ID psychology are used to modify a famous TN work respectively and synergically, and the modified work is appreciated by respondents to collect their comments. The results corroborate that 62% of the respondents like original articles, but their likability scores have decreased for individually modified work by AI or ID psychology. In comparison, under the synergic modification efforts of AI and ID psychology, the popularity of the modified work has increased slightly, with 65% of the respondents showing a likability to read. Therefore, it is concluded that literary modification by single ID psychology or AI technology will reduce the reading threshold by trading off the literary value of the original work. The core of literary creation depends on human intelligence, and AI might still not be able to generate high-standard literary works independently because human minds and thoughts cannot be controlled and predicted by machines. The research results provide new ideas and improvement directions for the field of AI-assisted writing.

Abstract
In the current study, we examined the degree to which sudden gains (large, rapid, and stable symptom reduction in a one-session interval) predicted treatment outcome in adults randomized to two different trauma-focused treatments. Adults diagnosed with PTSD were randomized to either written exposure therapy (WET; n = 63), a brief, exposure-based treatment for posttraumatic stress disorder (PTSD), or the more time-intensive Cognitive Processing Therapy (CPT; n = 63). Findings showed that 20.6% of participants who received WET and 17.5% of participants who received CPT experienced sudden gains. Sudden gains occurred earlier in WET (M session = 2.69, SD = 0.75) than in CPT (M session = 5.64, SD = 3.01). However, there were no treatment condition differences in the magnitude of the sudden gains. Treatment outcomes were significantly better for those who experienced sudden gains compared with those who did not, regardless of treatment assignment. Exploratory analyses of participants' trauma narratives revealed that expressing more negative emotion predicted the occurrence of sudden gains in both treatment conditions. Negative beliefs about the self and others did not predict sudden gains. The findings are discussed in terms of how they may help identify individual early response patterns that predict outcomes in trauma-focused treatments.

Abstract
UNLABELLED Background: Given the prevalence of post-traumatic stress disorder (PTSD), particularly among military personnel, new treatment approaches are needed. One may be virtual relaxation interventions, especially 360-degree nature videos, since studies have demonstrated their relaxation effects for healthy participants. If these relaxation effects can be reproduced in patients with PTSD, they may offer a viable tool to reduce distress and hyperarousal. Objective: This research protocol describes a planned study that will examine the relaxation effects of 360-degree nature videos for patients with PTSD. It will also investigate whether these relaxation effects differ depending on the hardware immersion level (head-mounted display [HMD] vs. PC screen) in comparison to a control condition in which patients only listen to natural sounds and do not view a video. Finally, the effect of each intervention's dose duration (five vs. ten minutes) will be explored. Method: A counterbalanced, randomised, controlled, within-subject experiment will be conducted (sample size N = 36). Only soldiers aged 18 years or older with a primary diagnosis of PTSD will be included. Those with psychosis, substance dependence, a change in psychiatric medication within the last month, suicidal intent, and motion sickness will be excluded. All patients will experience the HMD, PC, and control conditions once for five or ten minutes. Self-reported relaxation measures will be collected before and after, and patients' skin conductance level, heart rate, and heart rate variability will be assessed during each condition. Semi-structured interviews will be conducted to examine the patients' experiences in detail. Conclusions: This feasibility study will provide initial evidence of whether viewing 360-degree nature videos via HMD or PC screen is relaxing for patients with PTSD and whether the effects are greater compared with the control condition. The study will also validate the dose duration and thereby informing a subsequent confirmatory interventional trial. Trial registration: DRKS00020277. HIGHLIGHTS This randomised controlled feasibility study will examine whether 360-degree nature videos are a suitable relaxation intervention for military personnel with post-traumatic stress disorder.

Abstract
Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) is an effective treatment for children impacted by trauma, and non-offending caregivers play an important role in this treatment. This study aims to identify correlates of four caregiver variables that have been identified as predictors of child outcomes in TF-CBT: support, cognitive-emotional processing, avoidance, and blame/criticism. Audio recorded sessions were coded from a community effectiveness trial of TF-CBT that included 71 child-caregiver dyads participating in the trauma narration and processing phase of treatment. Regression analyses were conducted to examine caregiver trauma history and child baseline symptoms (internalizing, externalizing, and posttraumatic stress disorder [PTSD] symptoms) as predictors of caregiver behavior during the trauma processing sessions. Caregivers who reported exposure to more trauma types exhibited more in-session avoidance and also processing during the trauma processing phase of treatment. Child symptoms at baseline did not predict caregiver in-session behaviors. Bivariate correlations were used to investigate concurrent associations between mean levels of in-session caregiver behaviors and in-session child distress (negative emotion, hopelessness, negative behaviors). More caregiver blame/criticism was associated with more in-session child distress on all three measures. Caregiver avoidance was associated with more child negative emotion and hopelessness. Findings may help identify therapeutic targets when working with caregivers to promote change and enhance TF-CBT outcomes.

Abstract
OBJECTIVES How narrative identity and well-being are intertwined as emerging adults process their lived experiences remains a critical theoretical and empirical question. We studied narrative identity among US emerging adults in a multiphase study. We aimed to test (1) if and how narrative identity themes (i.e., coherence, agency, growth) change rapidly across repeated narrations; (2) are related to reports of psychological adjustment (i.e., well-being, recent stress) over time; and (3) whether the valence of the autobiographical event nuanced the ways narrative identity and adjustment co-evolve. METHODS In a mini-longitudinal study conducted over three months, 300 adults aged 18-to-29-years (M age = 24.39 years; 60% women) provided autobiographical narratives about high-point and low-point (LP) life events at five time points, as well as repeated reports on well-being and recent stress. RESULTS Overall, coherence showed (1) the most consistency across time and valence than other narrative themes and (2) the most consistent associations with adjustment. In multilevel models, LP coherence and LP growth coincided with higher levels of adjustment. CONCLUSIONS Findings reinforce the ways narrative identity reflects dynamic processes of understanding the events of one's life, and the ways individual differences in framing and reasoning about life are important for psychological adjustment.

Souza RR, Robertson NM, McIntyre CK, Rennaker RL, Hays SA, Kilgard MP. Vagus nerve stimulation enhances fear extinction as an inverted-U function of stimulation intensity. Exp Neurol 2021; 341:113718. [PMID: 33844986 DOI: 10.1016/j.expneurol.2021.113718] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Revised: 03/22/2021] [Accepted: 04/05/2021] [Indexed: 02/07/2023]
Abstract
Studies in rodents indicate that pairing vagus nerve stimulation (VNS) with extinction training enhances fear extinction. However, the role of stimulation parameters on the effects of VNS remains largely unknown. Identifying the optimal stimulation intensity is a critical step in clinical translation of neuromodulation-based therapies. Here, we sought to investigate the role of stimulation intensity in rats receiving VNS paired with extinction training in a rat model for Posttraumatic Stress Disorder (PTSD). Male Sprague-Dawley rats underwent single prolonged stress followed by a severe fear conditioning training and were implanted with a VNS device. After recovery, independent groups of rats were exposed to extinction training paired with sham (0 mA) or VNS at different intensities (0.4, 0.8, or 1.6 mA). VNS intensities of 0.4 mA or 0.8 mA decreased conditioned fear during extinction training compared to sham stimulation. Pairing extinction training with moderate VNS intensity of 0.8 mA produced significant reduction in conditioned fear during extinction retention when rats were tested a week after VNS-paired extinction. High intensity VNS at 1.6 mA failed to enhance extinction. These findings indicate that a narrow range of VNS intensities enhances extinction learning, and suggest that the 0.8 mA VNS intensity used in earlier rodent and human stroke studies may also be the optimal in using VNS as an adjuvant in exposure therapies for PTSD.

Abstract
Objective: To conduct an interim analysis of data collected from an ongoing multisite randomized clinical trial (RCT) assessing the effectiveness of Trauma Center Trauma-Sensitive Yoga (TCTSY) for post-traumatic stress disorder (PTSD) among women veterans with PTSD related to military sexual trauma (MST). The purpose of the interim analysis was to assess outcomes from the primary site, which is geographically, demographically, culturally, and procedurally distinct from the second site. Design: RCT was conducted within a Veterans Administration Health Care System. Data collection included preintervention through 3 months postintervention. Participants: Enrollment for the main site was 152 women. The sample size for the intent-to-treat analysis was 104. The majority were African American (91.3%) with a mean age of 48.46 years. Intervention: The TCTSY intervention (n = 58) was conducted by TCTSY-certified yoga facilitators and consisted of 10 weekly 60-min group sessions. The control intervention, cognitive processing therapy (CPT; n = 46), consisted of 12 90-min weekly group sessions conducted per Veterans Administration protocol by clinicians in the PTSD Clinic. Outcome measures: The Clinician Administered PTSD Scale for DSM-5 (CAPS-5) was used to assess current PTSD diagnosis and symptom severity, including overall PTSD and four symptom clusters. The PTSD checklist for DSM-5 (PCL-5) was used to obtain self-report of PTSD symptom severity, including total score and four symptom clusters. Results: The findings reported here are interim results from one clinical site. For both the CAPS-5 and PCL-5, total scores and all four criterion scores decreased significantly (p < 0.01) over time in all five multilevel linear models within both TCTSY and CPT groups, without significant differences between groups. There were clinically meaningful improvements seen for both TCTSY and CPT with 51.1%-64.3% of TCTSY subjects and 43.5%-73.7% of CPT decreasing their CAPS-5 scores by 10 points or more. Effect sizes for total symptom severity were large for TCTSY (Cohen's d = 1.10-1.18) and CPT (Cohen's d = 0.90-1.40). Intervention completion was higher in TCTSY (60.3%) than in CPT (34.8%). Symptom improvement occurred earlier for TCTSY (midintervention) than for CPT (2 weeks postintervention). Safety: There were no unanticipated adverse events in this study. Conclusion: The results of this study demonstrate that TCTSY may be an effective treatment for PTSD that yields symptom improvement more quickly, has higher retention than CPT, and has a sustained effect. TCTSY may be an effective alternative to trauma-focused therapy for women veterans with PTSD related to MST. The study is registered in ClinicalTrials.gov (CTR no.: NCT02640690).

Abstract
This study examines processes of change in trauma-focused cognitive behavioral therapy (TF-CBT) delivered to a community sample of 81 youth. Emotional processing theory (EPT) is used as an organizational framework. EPT highlights activating and changing pathological trauma-related responses and increasing adaptive responses across cognitive, emotional, behavioral, and physiological domains. We coded sessions during the trauma processing phase of TF-CBT to examine the extent to which pathological and adaptive trauma-related responses were activated across domains. Higher scores indicate that more domains (0-4) were activated at a threshold of moderate to high intensity. Curvilinear change (inverted U, increase then decrease) in multimodal negative response scores across sessions predicted improvement in internalizing and PTSD symptoms at posttreatment. Linear increases in multimodal positive responses predicted improvement in externalizing symptoms. Findings suggest value in activating and changing both pathological and adaptive trauma responses across multiple domains and examining nonlinear patterns of change.
