Presence of Psychiatric Assistance Dogs and Relation to Post-Traumatic Stress Disorder Treatment Outcomes: A Nonrandomized, Observational Study in a Military Sample

The purpose of this study was to examine differences between military veterans and service members with and without a psychiatric assistance dog (PAD) who were receiving cognitive behavioral therapy (CBT) for post-traumatic stress disorder (PTSD). Six hundred eighty-two military veterans presented at a 2-week intensive, outpatient CBT program for PTSD from February 2016 to February 2020. Self-reports of symptoms and rates of treatment completion by PAD ownership were assessed. Patients with PADs ( n = 93) reported higher scores on the PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) ( P = .04; Cohen's d = 0.23) and Neurobehavioral Symptom Inventory ( P < .01; Cohen's d = 0.34) at baseline. PTSD symptom change was comparable between participants with and without PADs ( P > .05). Dropout was higher among owners of PADs, but this difference was not significant ( P = .11). Among military populations, those with PADs may experience more severe PTSD and neuro-cognitive symptoms, but having a PAD was not associated with treatment outcome in intensive CBT.

Psychosocial Interventions for the Treatment of Functional Abdominal Pain Disorders in Children

Functional abdominal pain disorders (FAPDs) can severely affect the life of children and their families, with symptoms carrying into adulthood. Management of FADP symptoms is also a financial and time burden to clinicians and health care systems. To systematically review various randomized clinical trials (RCTs) on the outcomes of cognitive behavioral therapy (CBT), educational support, yoga, hypnotherapy, gut-directed hypnotherapy, guided imagery, and relaxation in the management of FAPDs. PubMed, MEDLINE, Embase, PsycINFO, and Cochrane Library. All RCTs that compared psychosocial interventions with any control or no intervention, for children aged 4 to 18 years with FAPDs. Pairs of the authors independently extracted data of all included studies, using a predesigned data extraction sheet. One author acted as arbitrator. Risk of bias was assessed using the Cochrane risk of bias tool, and certainty of the evidence for all primary outcomes was analyzed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) framework. Primary outcomes were treatment success, pain frequency, pain intensity, and withdrawal owing to adverse events. Dichotomous outcomes were expressed as risk ratio (RR) with corresponding 95% CIs. Continuous outcomes were expressed as mean difference (MD) or standardized MD with 95% CI. A total of 33 RCTs with 2657 children (median [range] age, 12 [7-17] years; 1726 girls [67.3%]) were included. Twelve studies compared CBT with no intervention, 5 studies compared CBT with educational support, 3 studiescompared yoga with no intervention, 2 studies compared hypnotherapy with no intervention, 2 studies compared gut-directed hypnotherapy with hypnotherapy, and 2 studies compared guided imagery with relaxation. Seven studies evaluated other unique comparisons (eg, visceral osteopathy vs normal osteopathy). Per the GRADE framework, owing to risk of bias, there was moderate certainty in evidence that CBT was associated with higher treatment success numbers (n = 324 children; RR, 2.37; 95% CI 1.30-4.34; number needed to treat [NNT] = 5), lower pain frequency (n = 446 children; RR, -0.36; 95% CI, -0.63 to -0.09), and lower pain intensity (n = 332 children; RR, -0.58; 95% CI, -0.83 to -0.32) than no intervention. Owing to high imprecision, there was low certainty in evidence that there was no difference between CBT and educational support for pain intensity (n = 127 children; MD, -0.36; 95% CI, -0.87 to 0.15). Owing to risk of bias and imprecision, there was low certainty in evidence that hypnotherapy resulted in higher treatment success compared with no intervention (n = 91 children; RR, 2.86; 95% CI, 1.19-6.83; NNT = 5). Owing to risk of bias and imprecision, there was low certainty in evidence that yoga had similar treatment success to no intervention (n = 99 children; RR, 1.09; 95% CI, 0.58-2.08). Results of this systematic review and meta-analysis suggest that CBT and hypnotherapy may be considered as a treatment for FAPDs in childhood. Future RCTs should address quality issues to enhance the overall certainty of the results, and studies should consider targeting these interventions toward patients who are more likely to respond.

Patients' self-perceived strengths increase during treatment and predict outcome in outpatient cognitive behavioral therapy.

Modern conceptualizations suggest the independence of positive and negative mental health constructs. Research of positive constructs in psychotherapy is scarce. This study analyzed the development of patients' strengths during psychotherapy and whether pre-therapy strengths incrementally predict treatment outcome. Two hundred and twopatients (56.44% female, mean age = 42.49) treated by 54 therapists underwent cognitive behavioral therapy. Patients' strengths in different contexts as well as psychopathology, interpersonal problems, and self-esteem were assessed at the beginning and end of therapy. Strengths increased in the contexts of everyday life (EvdayS; d = 0.44, p < 0.001) and current problems (ProbS; d = 0.70, p < 0.001). Strengths in the context of previous crises that were managed successfully (CrisesS) did not change. However, baseline scores of CrisesS were a significant incremental predictor of all outcomes. A differentiated assessment of positive constructs is useful for outcome prediction and the implementation of strength-based interventions.

Therapeutic Alliance and Treatment Outcome in Cognitive Behavior Therapy for Obsessive-Compulsive Disorder.

ObjectiveTherapeutic alliance has consistently been found to predict treatment outcomes across various psychotherapies and patient diagnosis. However, the relationship between therapeutic alliance and outcome in Cognitive Behavioral Therapy (CBT) has shown mixed results. This study investigated the impact of different aspects of therapeutic alliance in CBT for Obsessive-Compulsive Disorder (OCD).MethodData from two previously completed randomized controlled trials of 208 patients with OCD and their therapists were analyzed. Therapeutic alliance was assessed at week 4 of treatment with the patient-rated and therapist-rated Working Alliance Inventory (WAI), which includes three subscales to measure alliance domains (Goal, Task and Bond). Higher WAI score reflects a better therapeutic relationship. OCD severity was rated by independent assessors at baseline and post-treatment using the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). Linear regression analyses were used to examine the effects of the different aspects of therapeutic alliance on treatment outcome, adjusted for baseline symptom severity.ResultsA higher total WAI score as rated by therapists significantly predicted a lower post-treatment Y-BOCS. Further, higher scores on the Goal and Task subscales of the WAI were associated with lower post-treatment severity. However, these significant outcomes reflected only small effect sizes.ConclusionsIn the treatment of OCD, the strength of the therapeutic alliance contributes to outcomes, though to a limited extent. Effective OCD treatment involves the delivery of specific therapy interventions, in the context of a strong therapeutic alliance.

Delay Discounting in Gambling Disorder: Implications in Treatment Outcome.

Impulsive choice, measured by delay discounting (DD) tasks, has been shown in patients with gambling disorders (GD). However, the impact of DD and treatment outcome has been scarcely explored in GD patients. The aims of this study were: (1) to examine the baseline association between DD and clinical variables in GD patients depending on their age and gambling preferences (strategic vs. non-strategic); and (2) to estimate the predictive role of DD on poorer outcomes of cognitive-behavioral therapy (CBT) when considering also the effect of other clinical variables. 133 treatment-seeking male GD patients were evaluated at baseline with a DD task and measures of GD severity, personality traits and psychopathology. Treatment outcome was measured in terms of dropout from CBT and relapses. Results showed baseline associations between DD and GD severity (correlation coefficient R = 0.408 among strategic gamblers and R = 0.279 among mixed gamblers) and between DD and positive/negative urgency (R = 0.330 for the youngest patients, R = 0.244 for middle age, and around R = 0.35 for gamblers who reported preferences for strategic games). Other personality traits such as high harm avoidance and low cooperativeness were also related to DD at baseline (R = 0.606 among strategic gamblers). Regarding treatment outcome, a steeper discount rate predicted a higher risk of relapses in strategic gamblers (odds ratio OR = 3.01) and middle-age ones (OR = 1.59), and a higher risk of dropout in younger gamblers (OR = 1.89), non-strategic gamblers (OR = 1.70) and mixed gamblers (R = 4.74). GD severity mediated the associations between age, DD, personality traits and poor CBT outcome. In conclusion, impulsive choice affects treatment response in individuals with GD and may interfere with it to a significant extent. Considering DD in GD, patients seeking treatment could help control its impact on treatment adherence and relapses.

Homework

In commemoration of Dr. Aaron T. Beck’s enormous contributions to our field, I comment on the state of our knowledge regarding the role of homework in cognitive behavioral therapy. The available evidence suggests homework is a contributor to positive therapeutic outcomes in cognitive behavioral therapy. Although therapists play an important role in facilitating clients’ engagement with homework as they develop greater facility with CBT skills, little is known about the contributions of specific approaches to promoting homework engagement. I highlight some of these strategies and discuss the need for researchers to empirically evaluate them.

Behavioral dysregulations by chronic alcohol abuse. Motivational enhancement therapy and cognitive behavioral therapy outcomes.

Patients with alcohol use disorder (AUD) do not manifest homogeneous clinical symptoms. Various studies described both cognitive impairments and psychiatric disorders among people with AUD. This disorder is one of the most frequent mental disorders in developed countries, due to excessive alcohol consumption. Alcohol is toxic as it increases the production of reactive oxygen species (ROS) and can cause dependence. This causes negative effects on brain development and cognitive functions that affect the individual's work, health, and social life. Current pharmacology treatment for alcohol addiction is based on direct action against the neurotransmitters involved in alcohol dependence. AUD patients without comorbid psychiatric disorders or severe cognitive deficits are defined as "pure alcoholics". To date, poor is known about effective treatments for this typology of AUD patients. Psychotherapy is largely used in resolving many psychiatric disorders, including substance use disorders. Motivational enhancement therapy (MET) and cognitive-behavioral therapy (CBT) are two psychotherapies used to achieve and maintain abstinence in patients affected by substance use disorders. This short review aims to describe two CBT and MET and to present the advantages and disadvantages of these two psychotherapies in the treatment of AUD.

Emotion Regulation as a Moderator of Outcomes of Transdiagnostic Group Cognitive-Behavioral Therapy for Emotional Disorders

The aim of this study was to examine the potential moderating effect of baseline emotion regulation skills—cognitive reappraisal and expressive suppression—on the relationship between treatment allocation and treatment outcomes in primary care patients with emotional symptoms. A total of 631 participants completed scales to evaluate emotion regulation, anxiety, depression, functioning, and quality of life (QOL). The moderation analysis was carried out using the SPSS PROCESS macro, version 3.5. Expressive suppression was a significant moderator in the relationship between treatment allocation and treatment outcomes in terms of symptoms of anxiety (b = −0.530, p = .026), depression (b = −0.812, p = .004), and QOL (b = 0.156, p = .048). Cognitive reappraisal acted as a moderator only in terms of QOL (b = 0.217, p = .028). The findings of this study show that participants with higher scores of expressive suppression benefited more from the addition of transdiagnostic cognitive-behavioral therapy to treatment as usual (TAU) in terms of anxiety and depressive symptoms, and QOL. Individuals with higher levels of cognitive reappraisal obtained a greater benefit in terms of QOL from the addition of psychological treatment to TAU. These results underscore the relevant role that emotion regulation skills play in the outcomes of psychological therapy for emotional symptoms.

DNA-methylation dynamics across short-term, exposure-containing CBT in patients with panic disorder

Interaction of genetic predispositions and environmental factors via epigenetic mechanisms have been hypothesized to play a central role in Panic Disorder (PD) aetiology and therapy. Cognitive Behavioral Therapy (CBT), including exposure interventions, belong to the most efficient treatments of PD although its biological mechanism of action remains unknown. For the first time, we explored the dynamics and magnitude of DNA-methylation and immune cell-type composition during CBT (n = 38) and the therapeutic exposure intervention (n = 21) to unravel their biological correlates and identify possible biomarkers of therapy success. We report transient regulation of the CD4 + T-Cells, Natural Killers cells, Granulocytes during exposure and a significant change in the proportions of CD4 + T cells, CD8 + T cells and B-Cells and Granulocytes during therapy. In an epigenome-wide association study we identified cg01586609 located in a CpG island and annotated to the serotonin receptor 3 A (HTR3A) to be differentially methylated during fear exposure and regulated at gene expression level with significant differences between remitters and non-remitters (p = 0.028). We moreover report cg01699630 annotated to ARG1 to undergo long lasting methylation changes during therapy (paired t test, genome-wide adj.p value = 0.02). This study reports the first data-driven biological candidates for epigenetically mediated effects of acute fear exposure and CBT in PD patients. Our results provide evidence of changes in the serotonin receptor 3 A methylation and expression during fear exposure associated with different long-term CBT trajectories and outcome, making it a possible candidate in the search of markers for therapy success. Finally, our results add to a growing body of evidence showing immune system changes associated with PD.

Outcomes of student trainee-delivered cognitive-behavioral therapy (CBT) on internalizing symptoms, CBT skills, and life satisfaction.

Increased quality of life (QoL) is rated by patients as a primary factor in determining recovery from psychopathology. Cognitive-behavioral therapies (CBTs) are the most well-researched psychotherapies for internalizing disorders and appear effective at reducing symptoms even when delivered by trainees. Existing research suggests that the effects of CBTs on QoL are more modest than their effects on symptoms. However, little is known about the effects of trainee-delivered CBT on life satisfaction, a subjective measure of QoL. We analyzed data from 93 clients treated by students (n=23) in a graduate-level training clinic using an intent-to-treat approach, completers case analyses, and random forest imputation. Across methods of handling missing data, improvements in anxiety, depression, and CBT skills were more marked than improvements in QoL. Exploratory analyses suggested baseline life satisfaction was the strongest predictor of end-of-treatment life satisfaction. Future research should explore alternatives to "standard" CBT for clients with low life satisfaction.

Mechanisms of exposure and response prevention in obsessive-compulsive disorder: effects of habituation and expectancy violation on short-term outcome in cognitive behavioral therapy

BackgroundExposure and response prevention is effective and recommended as the first choice for treating obsessive-compulsive disorders (OCD). Its mechanisms of action are rarely studied, but two major theories make distinct assumptions: while the emotional processing theory assumes that treatment effects are associated with habituation within and between exposure sessions, the inhibitory learning approach highlights the acquisition of additional associations, implying alternative mechanisms like expectancy violation. The present study aimed to investigate whether process variables derived from both theories predict short-term outcome.MethodIn a university outpatient unit, 110 patients (63 female) with OCD received manual-based cognitive-behavioral therapy with high standardization of the first two exposure sessions. Specifically, therapists repeated the first exposure session identically and assessed subjective units of distress as well as expectancy ratings in the course of exposure sessions. Based on these data, individual scores for habituation and distress-related expectancy violation were calculated and used for prediction of both percentage change on the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) and remission status after 20 therapy sessions.ResultsIn a multiple regression model for percentage change, within-session habituation during the first exposure was a significant predictor, while in a logistic regression predicting remission status, distress-related expectancy violation during the first exposure revealed significance. A path model further supported these findings.ConclusionsThe results represent first evidence for distress-related expectancy violation and confirm preliminary findings for habituation, suggesting that both processes contribute to treatment benefits of exposure in OCD, and both mechanisms appear to be independent.

Session-to-session effects of therapist adherence and facilitative conditions on symptom change in CBT and IPT for depression

ABSTRACT Objective The objective of this study was to analyze the effect of adherence to both specific technique factors and facilitative condition variables (e.g., therapists’ involvement, understanding and support) in Cognitive Behavior Therapy (CBT) and Interpersonal Psychotherapy (IPT). In addition, we were interested in whether the effect of therapist adherence would depend on the level of the working alliance. Method Three sessions each from 74 patients diagnosed with Major Depressive Disorder who were randomized to 14 sessions of IPT or CBT were rated for adherence using a modified version of The Collaborative Study Psychotherapy Rating Scale—6 (CSPRS-6). Data was analyzed using Multilevel Modeling. Results No effects of adherence to specific factors on outcome were found in neither CBT nor IPT. Facilitative conditions were associated with better outcome in CBT but not in IPT, even after adjustment for the quality of the working alliance. No interaction effects were found. Conclusions Our findings highlight the importance of relational factors in CBT, but do not support the need for specific adherence to any of the two treatments. Possible explanations of the findings and directions for future research are discussed. Trial registration: ClinicalTrials.gov identifier: NCT01851915.

Body Dysmorphic Symptoms in Youth with Obsessive-compulsive Disorder: Prevalence, Clinical Correlates, and Cognitive Behavioral Therapy Outcome.

The aims of the study were to estimate the prevalence of body dysmorphic symptoms in a sample of children and adolescents with obsessive-compulsive disorder, possible clinical correlates and whether BDD symptoms predict poorer treatment outcomes after cognitive behavioral therapy. The study included 269 children and adolescents with OCD, aged 7-17 years, from Denmark, Sweden, and Norway, who were treated with 14 weekly sessions of manualized, exposure-based CBT. Twenty-one patients (7.8%) had BDD symptoms. BDD symptoms were associated with older age (p = 0.003) and a higher prevalence of comorbid anxiety disorders (p = 0.025). In addition, patients with BDD symptoms endorsed a greater number of OCD symptoms than did those without BDD symptoms. Having symptoms of BDD did not affect the CBT outcome on OCD. The results of the study suggest that CBT for OCD is equally effective for those with and without comorbid BDD symptoms.

Distress tolerance: prospective associations with cognitive-behavioral therapy outcomes in adults with posttraumatic stress and substance use disorders

ABSTRACT 74Distress tolerance (DT; perceived or actual ability to tolerate aversive physical or emotional states) is related to both posttraumatic stress disorder (PTSD) symptoms and substance use disorders (SUD). This investigation evaluates self-report and behavioral measures of DT as potential predictors of PTSD and SUD cognitive-behavioral therapy outcomes. Participants included 41 treatment-seeking adults (53.7% women; 73.2% African American; M age = 44.90, SD = 9.68) who met at least four symptoms of DSM-5 PTSD and DSM-IV substance dependence, assessed via structured interviews. At baseline (pre-treatment), participants completed the Distress Tolerance Scale (DTS), Mirror-Tracing Persistence Task (MTPT), Breath Holding task, and Paced Auditory Serial Addition Task. The Clinician-Administered PTSD Scale for DSM-5 severity scores and percent days of primary substance use, measured via Timeline Follow-back, were used as indicators of PTSD symptoms and substance use, respectively. Covariates included treatment condition, baseline PTSD symptom severity, and baseline substance use. Lower perceived DT at baseline (DTS total score) was associated with higher PTSD symptom severity at end-of-treatment. Lower behavioral DT at baseline (MTPT duration) was associated with higher substance use at the conclusion of treatment (i.e. proportion of number of use days to total number of days between two final treatment sessions).

Very long-term outcome of cognitive behavioral therapy for insomnia: one- and ten-year follow-up of a randomized controlled trial

ABSTRACT Insomnia is a common and chronic disorder, and cognitive behavioral therapy (CBT) is the recommended treatment. Very long-term follow-ups of CBT are very rare, and this study aimed to investigate if improvements were stable one and ten years after CBT for insomnia (CBT-i). Based on a three-armed randomized controlled trial of bibliotherapeutic CBT-i, participants received an insomnia-specific self-help book and were randomized to therapist guidance, no guidance, or a waitlist receiving unguided treatment after a delay. Six weeks of treatment was given to 133 participants diagnosed with insomnia disorder. After one and ten years, participants were assessed with self-reports and interviews. Improvements were statistically significant and well maintained at one- and ten-year follow-ups. Average Insomnia Severity Index score [95%CI] was 18.3 [17.7–18.8] at baseline, 10.1 [9.3–10.9] at post-treatment, 9.2 [8.4–10.0] at one- and 10.7 [9.6–11.8] at ten-year follow-up, and 64% and 66% of participants no longer fulfilled criteria for an insomnia diagnosis at one and ten years, respectively. Positive effects of CBT were still present after ten years. Insomnia severity remained low, and two-thirds of participants no longer fulfilled criteria for an insomnia diagnosis. This extends previous findings of CBT, further confirming it as the treatment of choice for insomnia.

Clustering Treatment Outcomes in Women with Gambling Disorder

The rising prevalence of gambling disorder (GD) among women has awakened considerable interest in the study of therapeutic outcomes in females. This study aimed to explore profiles of women seeking treatment for GD based on a set of indicators including sociodemographic features, personality traits, clinical state at baseline, and cognitive behavioral therapy (CBT) outcomes. Two-step clustering, an agglomerative hierarchical classification system, was applied to a sample of n = 163 women of ages ranging from 20 to 73 years-old, consecutively attended to by a clinical unit specialized in the treatment of G. Three mutually exclusive clusters were identified. Cluster C1 (n = 67, 41.1%) included the highest proportion of married, occupationally active patients within the highest social status index. This cluster was characterized by medium GD severity levels, the best psychopathological functioning, and the highest mean in the self-directedness trait. C1 registered 0% dropouts and only 14.9% relapse. Cluster C2 (n = 63; 38.7%) was characterized by the lowest GD severity, medium scores for psychopathological measures and a high risk of dropout during CBT. Cluster C3 (n = 33; 20.2%) registered the highest GD severity, the worst psychopathological state, the lowest self-directedness level and the highest harm-avoidance level, as well as the highest risk of relapse. These results provide new evidence regarding the heterogeneity of women diagnosed with GD and treated with CBT, based on the profile at pre- and post-treatment. Person-centered treatments should include specific strategies aimed at increasing self-esteem, emotional regulation capacities and self-control of GD women.

Exposure Quality in Cognitive Behavioral Treatment for Youth Anxiety Disorders\u2014Predictors and Associations with Outcomes

To optimize cognitive behavioral therapy (CBT) outcomes for anxiety disorders in youth, more knowledge is needed about how specific CBT components work. Exposure to feared situations is an effective CBT component. However, there is little observation-based empirical research on how exposure relates to outcomes and other clinical variables. In a randomized controlled community clinic trial for youth with anxiety disorders, observers reliably rated exposure quality for 68 youths aged 8 to 15 years based on 118 videotaped sessions. The treatment program was the manual-based FRIENDS program. Three exposure quality elements (preparation, post-processing, and parent contribution to exposure) were examined in relation to pre-treatment demographic and clinical variables, outcomes, and youth- and therapist-rated alliance using multilevel hierarchical regression models. The outcomes were diagnostic recovery, clinical severity and anxiety symptoms change from pre- to post-treatment and one-year follow-up, and treatment dropout. The results showed that parent contribution to exposure was higher for boys and younger children. Parent contribution to exposure, but no other exposure element, was associated with a larger likelihood of diagnostic recovery and larger clinical severity reduction at one-year follow-up. Exposure quality was unrelated to outcomes at post-treatment, dropout, or alliance. We conclude that enhancing parent contribution to exposure during treatment could improve long-term outcomes after CBT for youth anxiety disorders. Exposure elements should be observed in larger samples to further examine their potential role for CBT outcomes.

Adaptive Riding Incorporating Cognitive-Behavioral Elements for Youth with Anxiety: An Exploratory Randomized Controlled Study

Abstract Between 15% to 20% of youth meet diagnostic criteria for anxiety, yet most do not receive treatment due to workforce shortages, under-detection, or barriers that dissuade families from seeking services in traditional settings. Equine-assisted services (EAS) include several promising approaches to reach populations who do not access traditional therapies. Few studies using rigorous methods have been conducted on EAS for youth. This study examined feasibility and outcomes of a 10-session Cognitive Behavioral Therapy (CBT)-based adaptive riding intervention (hereafter called Reining in Anxiety) delivered by trained equine professionals. Forty-one youth 6-16 years of age were recruited from GallopNYC, an adaptive horseback riding center in the NYC metro area. Youth were randomized to an experimental group (n=22) or services as usual (n=19), a standard adaptive riding group (services as usual or SAU). Severity of anxiety symptoms, anxiety in close relationships, and emotional self-efficacy were assessed at baseline and at the end of treatment. Fidelity to the manual was excellent, ranging from 88.9% to 100%. There was a non-significant trend in the experimental group towards greater improvement with higher number of sessions completed. Youth in the Reining in Anxiety group displayed significant reductions in anxiety (t=4.426, df=38, p=0.042) and improvement in emotional self-efficacy at posttest (t=4.132, df =38, p=0.049) in comparison to the SAU group. No significant differences were found between groups for anxiety in close relationships. This study suggests that a CBT-based adaptive riding intervention delivered by non-mental health equine professionals following a detailed manual can reduce youth anxiety symptoms and be delivered with fidelity by riding instructors. These findings have implications for families seeking non-traditional services.

Anterior cingulate cortex activation during attentional control as a transdiagnostic marker of psychotherapy response: a randomized clinical trial.

Anterior cingulate cortex (ACC) response during attentional control in the context of task-irrelevant emotional faces is a promising biomarker of cognitive behavioral therapy (CBT) outcome in patients with social anxiety disorder (SAD). However, it is unclear whether this biomarker extends to major depressive disorder (MDD) and is specific to CBT outcome. In the current study, 72 unmedicated patients with SAD (n = 39) or MDD (n = 33) completed a validated emotional interference paradigm during functional magnetic resonance imaging before treatment. Participants viewed letter strings superimposed on task-irrelevant threat and neutral faces under low perceptual load (high interference) and high perceptual load (low interference). Biomarkers comprised anatomy-based rostral ACC (rACC) and dorsal ACC (dACC) response to task-irrelevant threat (>neutral) faces under low and high perceptual load. Patients were randomly assigned to 12 weeks of CBT or supportive therapy (ST) (ClinicalTrials.gov identifier: NCT03175068). Clinician-administered measures of social anxiety and depression severity were obtained at baseline and every 2 weeks throughout treatment (7 assessments total) by an assessor blinded to the treatment arm. A composite symptom severity score was submitted to latent growth curve models. Results showed more baseline rACC activity to task-irrelevant threat>neutral faces under low, but not high, perceptual load predicted steeper trajectories of symptom improvement throughout CBT or ST. Post-hoc analyses indicated this effect was driven by subgenual ACC (sgACC) activation. Findings indicate ACC activity during attentional control may be a transdiagnostic neural predictor of general psychotherapy outcome.

The uptake and outcomes of Internet-based cognitive behavioural therapy for health anxiety symptoms during the COVID-19 pandemic

BackgroundInternet cognitive behavioural therapy (iCBT) for health anxiety has demonstrated efficacy but has not been evaluated during the COVID-19 pandemic. This study presents the first evaluation of the uptake and outcomes of iCBT for health anxiety during the COVID-19 pandemic. MethodsTHIS WAY UP is an Australian digital mental health service which delivers iCBT interventions to community members. We compared the uptake of THIS WAY UP’s iCBT course for health anxiety in an Australian adult sample who started the course before the pandemic (12th September 2019–11 th March 2020) to during the pandemic (12th March to 11th June 2020). The course was accessible to Australian adults over 18 years old, with no inclusion criteria. Outcomes included course registrations and commencements, lesson and course completion, and self-reported health anxiety (Short Health Anxiety Inventory), depression (Patient Health Questionnaire 9-item) and distress (Kessler-10). ResultsFrom March to June 2020, we observed significant increases in course registrations (N = 238 vs N = 1057); and course commencements (N = 126 vs. N = 778). Large, significant improvements in health anxiety (g = 0.89), and distress (K10: g = 0.91), and medium improvements in depression (g = 0.55) were found. Course completion during COVID was 30.5%. ConclusionsiCBT improved health anxiety during the COVID-19 pandemic, and provides scalable intervention that can address increased demands for mental health services in the community.
