RESUMEN
OBJECTIVE: Chronic pain often co-occurs with posttraumatic stress disorder (PTSD). The mutual maintenance hypothesis proposes that there may be shared underlying mechanisms of symptoms of pain exacerbating PTSD, and vice versa. The association between PTSD and pain intensity remains understudied. To elucidate the relationship, the present study examined the temporality of changes in PTSD severity and pain intensity in veterans undergoing intensive PTSD treatment. METHOD: Data from 332 veterans undergoing intensive 2-week cognitive processing therapy- (CPT-) based treatment (ITP) with adjunctive components (i.e., mindfulness, art therapy). Random intercepts cross-lagged panel models (RI-CLPMs) were used to examine within-subjects relationships between pain intensity and PTSD severity over the course of the program. RESULTS: Veterans experienced large PTSD severity reductions (Essg = 1.20; p < .001) and small pain severity reductions (Essg = 0.21; p < .001) over the course of treatment, despite pain not being a treatment target. RI-CLPMs revealed that PTSD severity significantly predicted subsequent pain severity. Results indicate the absence of a bidirectional relationship in that changes in pain intensity did not predict later PTSD severity improvement during the ITP. Time trends for both PTSD severity and pain intensity were generally consistent with respect to baseline demographic characteristics. CONCLUSION: Our findings support the mutual maintenance regarding the association between PTSD and pain intensity. Future research should investigate temporal associations in other evidence-based PTSD treatments and formats and evaluate the long-term impacts of PTSD treatment on pain intensity.

RESUMEN
Background: Growing evidence indicates that daily delivery of evidence-based PTSD treatments (e.g. Cognitive Processing Therapy (CPT)), as part of intensive PTSD treatment programmes (ITPs), is feasible and effective. Research has demonstrated that a 2-week CPT-based ITP can produce equivalent outcomes to a 3-week ITP, suggesting shorter treatment can also be highly effective. However, the extent to which ITP length and composition impact longer-term outcomes needs further study.Objective: We examined whether PTSD and depression symptoms 3-, 6-, and 12-months following completion of a 2-week ITP could be considered non-inferior, or equivalent, to those of a 3-week ITP.Method: Data from 638 veterans who participated in a 2-week CPT-based ITP were evaluated against 496 veterans who participated in a 3-week CPT-based ITP. A Bayes factor approach was used to examine whether PTSD and depression severity outcomes of the 2-week ITP could be considered equivalent to the 3-week ITP.Results: Participants across both ITPs reported large PTSD (d = 0.98) and moderate to large depression symptom reductions (d = 0.69) from baseline to 12-month follow-up. The PTSD and depression symptom reductions seen in the 2-week ITP were determined to be equivalent to those of the 3-week ITP.Conclusions: Low follow-up completion was a limitation. Future research might replicate the present findings using samples with greater follow-up rates and explore whether adjunctive services impact other relevant constructs, such as quality of life and functioning.
This study demonstrated that intensive PTSD treatment programmes for veterans can produce large and lasting PTSD and depression symptoms reductions.A 2-week intensive PTSD treatment programme that offered 37 fewer clinical hours was just as effective as a 3-week programme for veterans, with lasting symptom improvement up to 12 months after treatment.The 2-week programme focused primarily on individual Cognitive Processing Therapy delivered twice per day whereas the 3-week programme combined individual and group CPT and had a much larger number of adjunctive services.

Posttraumatic stress disorder (PTSD) commonly co-occurs with pain and has been implicated in the maintenance of chronic pain. However, limited research has examined whether intervening for PTSD can hinder or optimize treatment outcomes for co-occurring pain and PTSD. In the present study, we examined changes in pain, PTSD, and depressive symptoms among 125 veterans completing a 3-week cognitive processing therapy (CPT)-based intensive treatment program (ITP) for PTSD. We also explored whether pretreatment pain interference predicted changes in PTSD and depressive symptom severity and whether larger changes in pain interference over the course of treatment were associated with larger changes in PTSD and depressive symptom severity. Linear mixed models revealed that participants' pain interference decreased throughout treatment, d = 0.15, p = .039. Higher levels of pretreatment pain interference were associated with higher PTSD, p = .001, and depressive symptom severity, p = .014, over time. Larger reductions in pain interference corresponded to more improvement in PTSD symptoms, ß = -.03; p < .001, but not depressive symptoms. These findings indicate that ITPs for PTSD can reduce pain interferences, albeit to a small degree, and that reductions in pain interference can contribute to reductions in PTSD symptom severity. Future studies should examine which treatment components contribute to larger changes in symptom severity for veterans with co-occurring pain and PTSD.

OBJECTIVE: This study examined whether posttraumatic stress disorder (PTSD) symptom change during a 3- and 2-week intensive treatment program (ITP)-based in cognitive processing therapy was predictive of reduced suicidal ideation (SI) following treatment. METHOD: Veterans completed either a 3-week (n = 274, Mage = 42.35, SD = 9.43, 64.23% male, 65.33% White) or 2-week (n = 177, Mage = 42.90, SD = 9.81, 57.63% male, 66.67% White) ITP and self-reported PTSD, depression, and SI symptoms prior to, during, and 3 months following treatment. RESULTS: Mixed-effects-based two-stage location scale models assessed change in both overall PTSD severity over the course of the 3- and 2-week ITPs, as well as how this change predicted 3-month follow-up SI. Veterans in both programs reported moderate reductions in SI from baseline to posttreatment (3 weeks: d = 0.49; 2 weeks: d = 0.48). Of the 210 veterans across both programs who endorsed at least some SI at baseline, two-thirds (65.24%) reported reductions in SI posttreatment; three-quarters (74.45%) of these maintained posttreatment SI at 3-month follow-up that was lower than baseline levels. CONCLUSIONS: Both baseline SI and greater individual improvement in PTSD symptom severity during the ITPs were associated with lower SI at 3-month follow-up. Overall, study findings suggest that veterans with PTSD who also endorse SI can be successfully treated using the intensive delivery format and are likely to experience a reduction in SI both during and following treatment.

RESUMEN
Background: Intensive PTSD treatment programs (ITPs) are highly effective but tend to differ greatly in length and the number of adjunctive services that are provided in conjunction with evidence-based PTSD treatments. Individuals' treatment response to more or less comprehensive ITPs is poorly understood.Objective: To apply a machine learning-based decision-making model (the Personalized Advantage Index (PAI)), using clinical and demographic factors to predict response to more or less comprehensive ITPs.Methods: The PAI was developed and tested on a sample of 747 veterans with PTSD who completed a 3-week (more comprehensive; n = 360) or 2-week (less comprehensive; n = 387) ITP.Results: Approximately 12.32% of the sample had a PAI value that suggests that individuals would have experienced greater PTSD symptom change (5 points) on the PTSD Checklist for DSM-5 in either a more- or less comprehensive ITP. For individuals with the highest 25% of PAI values, effect sizes for the amount of PTSD symptom change between those in their optimal vs. non-optimal programs was d = 0.35.Conclusions: Although a minority was predicted to have benefited more from a program, there generally was not a substantial difference in predicted outcomes. Less comprehensive and thus more financially sustainable ITPs appear to work well for most individuals with PTSD.
A Personalized Advantage Index (PAI) was developed for a 3-week (more comprehensive) and a 2-week (less comprehensive) intensive PTSD treatment program to predict treatment responses.Using the PAI, approximately 12% of the sample was predicted to have experienced meaningfully greater in another program than the one in which they participated.Findings suggest a less comprehensive and more financially sustainable 2-week intensive PTSD treatment program would work well for most veterans in the present study.

Sudden gains have been found in PTSD treatment across samples and treatment modality. Sudden gains have consistently predicted better treatment response, illustrating clear clinical implications, though attempts to identify predictors of sudden gains have produced inconsistent findings. To date, sudden gains have not been examined in intensive PTSD treatment programs (ITPs). This study explored the occurrence of sudden gains in a 3-week and 2-week ITP (n = 465 and n = 235), evaluated the effect of sudden gains on post-treatment and follow-up PTSD severity while controlling for overall change, and used three machine learning algorithms to assess our ability to predict sudden gains. We found 31% and 19% of our respective samples experienced a sudden gain during the ITP. In both ITPs, sudden gain status predicted greater PTSD symptom improvement at post-treatment (t2 W=-8.57, t3 W=-14.86, p < .001) and at 3-month follow-up (t2 W=-3.82, t3 W=-5.32, p < .001). However, the effect for follow-up was no longer significant after controlling for total symptom reduction across the ITP (t2 W=-1.59, t3 W=-0.32, p > .05). Our ability to predict sudden gains was poor (AUC <.7) across all three machine learning algorithms. These findings demonstrate that sudden gains can be detected in intensive treatment for PTSD, though their implications for treatment outcomes may be limited. Moreover, despite the use of three machine-learning methods across two fairly large clinical samples, we were still unable to identify variables that accurately predict whether an individual will experience a sudden gain during treatment. Implications for clinical application of these findings and for future studies are discussed.

Introduction: Intensive or massed Cognitive Processing Therapy (CPT) for posttraumatic stress disorder (PTSD) has been found to result in significant PTSD symptom reductions. However, few studies to date have used qualitative approaches to systematically evaluate client reflections about massed treatment approaches for PTSD. To address this gap, the present study aimed to improve our understanding of trauma survivors' reflections following the completion of 1-week CPT.Method: We conducted semi-structured interviews with seven trauma survivors within 3-months of the completion of 1-week CPT. We used the scissor-and-sort technique to identify themes and subthemes in the qualitative data.Results: Using the scissor-and-sort technique, we generated five main themes and associated subthemes from the data. The main themes were: (a) tangible skills, (b) feasibility, (c) therapeutic process, (d) symptom presentation, and (e) treatment expectations.Conclusion: Collectively, our results suggested that 1-week CPT was feasible and led to changes in PTSD symptoms and improved cognitive and affective coping skills.

OBJECTIVE: Although there is mounting evidence that massed treatment for PTSD is both feasible and effective, many questions remain about the optimal length of intensive treatment programs (ITPs), as well as the role of adjunctive services, such as psychoeducation, mindfulness, and yoga. Our setting recently transitioned from a three-week ITP to a two-week program. Adjunctive services were reduced, but the amount of individual CPT between programs remained similar. The present study examined the effectiveness of a two-week ITP based on twice daily individual CPT sessions and evaluated the program's noninferiority to an established three-week ITP using a Bayesian analytical approach. METHOD: Bayesian linear mixed regression models were used to explore PTSD and depression changes over time, as well as predictors of change. Noninferiority of the two-week ITP to a three-week ITP was also established using a Bayes factor approach. RESULTS: Results indicate that program participants change meaningfully in both PTSD and depression severity over the course of treatment, and that changes in posttraumatic cognitions predict subsequent changes in these outcomes. Further, the two-week ITP can be considered noninferior to the three-week ITP in both clinical outcomes and overall satisfaction. CONCLUSIONS: In the context of intensive PTSD treatment, the content of the ITP appears to matter more than its overall length. Shorter programs have the potential to increase access and treatment capacity. Our findings demonstrate the importance of continuous and rigorous program evaluation. Limitations as well as future directions for research, such as identifying the most effective treatment components, are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Intensive treatment programs (ITPs) are successful at reducing posttraumatic stress disorder (PTSD) and depression symptoms in veterans. However, the role of the working alliance in the context of ITPs is largely unexplored. The purpose of this study was to examine veteran-rated working alliance with their individual cognitive processing therapy (CPT) provider as a predictor of changes in PTSD and depression symptoms as well as negative posttrauma cognitions in two unique ITP formats. Data were collected from 128 veterans who completed a 2-week ITP, involving 2 × individual CPT/day, as well as 73 veterans who completed a 3-week ITP, involving 1 × group CPT/day and 1 × individual CPT/day. Both ITPs included adjunctive wellness, skills, and psychoeducation services in addition to CPT. Linear mixed-effects models were used to determine whether changes in working alliance predicted changes in PTSD and depression symptoms. Stronger veteran-reported working alliance with their individual CPT therapist, most notably agreement on tasks, predicted significant reductions in both the 2-week and 3-week programs in PTSD (ps = .012 and .002, respectively) and depression symptoms (ps = .009 and .007, respectively) and negative posttrauma cognitions (ps = .009 and .016, respectively). These results highlight the importance of veterans' perceived working alliance with their individual treatment therapists in ITPs. Results suggest that a strong working alliance that is meaningful for treatment outcomes can be developed quickly despite the brevity of this intensive treatment format. Future research should examine ways to facilitate the development of a strong working alliance prior to or as early as possible in ITPs. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Research has supported the utility of brief intensive treatment programs (ITPs) which utilize interventions, such as Cognitive Processing Therapy (CPT), for reducing severity of symptoms among veterans with posttraumatic stress disorder (PTSD). These treatments have produced large overall reductions in PTSD severity and demonstrated the persistence of these gains following treatment. However, the potential effects of ITPs on mental, physical, and social functioning following treatment completion has been largely unexplored. We utilized data from 204 veterans and 5 service members who completed a 3-week CPT-based ITP and 3-month follow-up assessments. We used a two-stage mixed effects location-scale model approach to initially model each participant's amount of PTSD change over time and used these estimates to predict mental, physical, and social functioning three months following treatment. Veterans reported moderate improvements in mental, physical, and social functioning from pre-treatment to 3-month follow-up (ds = 0.52,.42,.55, and.47, respectively). Results indicated that reductions in PTSD severity during treatment, rather than fluctuation in symptom reporting from one assessment to the next, significantly predicted improved mental, physical, and social functioning at follow-up. This study supports the ability of ITPs to enact meaningful improvement in functioning among veterans with PTSD in a short timeframe.

Despite the established effectiveness of evidence-based PTSD treatments, not everyone responds the same. Specifically, some individuals respond early while others respond minimally throughout treatment. Our ability to predict these trajectories at baseline has been limited. Predicting which individuals will respond to a certain type of treatment can significantly reduce short- and long-term costs and increase the ability to preemptively match individuals with treatments to which they are most likely to respond. In the present study, we examined whether veterans' responses to a 3-week Cognitive Processing Therapy-based intensive PTSD treatment program could be accurately predicted prior to the first session. Using a sample of 432 veterans, and a wide range of demographic and clinical data collected during intake, we assessed six machine learning and statistical methods and their ability to predict fast and minimal responders prior to treatment initiation. For fast response classification, gradient boosted models (GBM) had the highest AUC-PR (0.466). For minimal response classification, elastic net (EN) had the highest mean CV AUC-PR (0.628). Using the best performing classifiers, we were able to predict both fast and minimal responders prior to starting treatment with relatively high AUC-ROC of 0.765 (GBM) and 0.826 (EN), respectively. These results may inform treatment modifications, although the accuracy may not be sufficient for clinicians to base inclusion/exclusion decisions entirely on the classifiers. Future research should evaluate whether these classifiers can be expanded to predict to which treatment type(s) an individual is most likely to respond based on various clinical, circumstantial, and biological features.

Posttraumatic stress disorder (PTSD) treatments are increasingly delivered in massed formats and have shown comparable results to standard, weekly treatment. To date, massed cognitive processing therapy (CPT), delivered daily, has been delivered primarily in combination with adjunctive services and among veteran populations, but it has not been rigorously evaluated as a standalone intervention. The present study evaluated 1-week massed CPT delivered virtually (i.e., via telehealth) to a community sample of trauma-exposed individuals (N = 24). Using a single-arm open-label design, participants received CPT twice per day for 5 days. The results indicated that most participants completed treatment (n = 23, 95.8%), and no adverse events were reported. Participants exhibited large reductions in clinician-rated, d = 2.01, and self-reported PTSD symptoms, d = 2.55, as well as self-reported depressive symptoms, d = 1.46. On average, participants reported a 5-point PTSD symptom reduction and 1-point reduction in depressive symptoms for each treatment day. Reductions in PTSD and depressive symptoms were maintained at 3-month follow-up. Overall, 1-week massed CPT delivered virtually was shown to be feasible and to result in rapid symptom reductions that were sustained over time. Virtual massed CPT has the potential to increase access to effective treatments and help trauma survivors restore aspects of their lives in short amounts of time.

OBJECTIVE: Evidence-based treatments for posttraumatic stress disorder (PTSD) can be effectively delivered over telehealth. There are, however, no studies that examine the effectiveness of delivering evidence-based treatments for PTSD in an intensive format via telehealth. Telehealth may be well-suited as a delivery modality because it may address barriers specific to intensive treatments. METHOD: To address this gap, we report on a case series of ten consecutively enrolled veterans (60% male; mean age 42.3, SD = 6.3) who participated in a virtual 2-week, cognitive processing therapy (CPT)-based intensive program. RESULTS: All (100%) participants completed treatment and reported large reductions in PTSD and depression symptoms pre- to posttreatment (Hedge's gws = 2.83 and gws = 1.97, respectively), pre- to 3-month follow-up (Hedge's gws = .99 and gws = 1.24, respectively), as well as very high satisfaction. CONCLUSIONS: Results of this case series suggest that evidence-based treatments for PTSD can be effectively delivered in intensive formats over telehealth and lay the foundation for more rigorously designed and larger scale research comparing virtual to in-person delivered intensive PTSD treatments.
