Effect of Psychotherapy on Intolerance of Uncertainty: A Systematic Review and Meta-Analysis.

Intolerance of uncertainty (IU) is the tendency to react negatively on affective, cognitive and behavioural levels to uncertain situations and to harbour negative beliefs about the implications of uncertainty. IU has been linked to psychopathology and shown to impact treatment outcomes. This study systematically reviewed the literature and performed a meta-analysis of the effects of psychotherapy on IU. A total of 22 studies (1491 participants) were identified in online searches and included in the meta-analyses. Analyses were performed on studies with passive and active control conditions. The pooled effect on IU from studies with passive control was large (g = -0.94 [95% CI -1.25 to -0.62]) but with significant heterogeneity. Pooled effects on IU from studies with active controls were not significant. Moderator analysis showed that among studies with a passive control condition, studies that recruited participants from clinical care facilities produced smaller effect sizes. Among studies with an active control condition, study quality significantly moderated the results, with higher quality leading to a larger effect size. These results indicate that changes in IU may be difficult to reliably achieve in psychotherapy and leave many questions about the effect of psychotherapy on IU unanswered, such as what active components produced the observed changes in studies with passive control.

Algorithm-based modular psychotherapy vs. cognitive-behavioral therapy for patients with depression, psychiatric comorbidities and early trauma: a proof-of-concept randomized controlled trial.

Effect sizes of psychotherapies currently stagnate at a low-to-moderate level. Personalizing psychotherapy by algorithm-based modular procedures promises improved outcomes, greater flexibility, and a better fit between research and practice. However, evidence for the feasibility and efficacy of modular-based psychotherapy, using a personalized treatment algorithm, is lacking. This proof-of-concept randomized controlled trial was conducted in 70 adult outpatients with a primary DSM-5 diagnosis of major depressive disorder, a score higher than 18 on the 24-item Hamilton Rating Scale for Depression (HRSD-24), at least one comorbid psychiatric diagnosis according to the Structured Clinical Interview for DSM-5 (SCID-5), a history of at least "moderate to severe" childhood maltreatment on at least one domain of the Childhood Trauma Questionnaire (CTQ), and exceeding the cut-off value on at least one of three measures of early trauma-related transdiagnostic mechanisms: the Rejection Sensitivity Questionnaire (RSQ), the Interpersonal Reactivity Index (IRI), and the Difficulties in Emotion Regulation Scale-16 (DERS-16). Patients were randomized to 20 sessions of either standard cognitive-behavioral therapy alone (CBT) or CBT plus transdiagnostic modules according to a mechanism-based treatment algorithm (MoBa), over 16 weeks. We aimed to assess the feasibility of MoBa, and to compare MoBa vs. CBT with respect to participants' and therapists' overall satisfaction and ratings of therapeutic alliance (using the Working Alliance Inventory - Short Revised, WAI-SR), efficacy, impact on early trauma-related transdiagnostic mechanisms, and safety. The primary outcome for efficacy was the HRSD-24 score at post-treatment. Secondary outcomes included, among others, the rate of response (defined as a reduction of the HRSD-24 score by at least 50% from baseline and a score <16 at post-treatment), the rate of remission (defined as a HRSD-24 score ≤8 at post-treatment), and improvements in early trauma-related mechanisms of social threat response, hyperarousal, and social processes/empathy. We found no difficulties in the selection of the transdiagnostic modules in the individual patients, applying the above-mentioned cut-offs, and in the implementation of MoBa. Both participants and therapists reported higher overall satisfaction and had higher WAI-SR ratings with MoBa than CBT. Both approaches led to major reductions of depressive symptoms at post-treatment, with a non-significant superiority of MoBa over CBT. Patients randomized to MoBa were nearly three times as likely to experience remission at the end of therapy (29.4% vs. 11.4%; odds ratio, OR = 3.2, 95% CI: 0.9-11.6). Among mechanism-based outcomes, MoBa patients showed a significantly higher post-treatment effect on social processes/empathy (p<0.05) compared to CBT patients, who presented an exacerbation on this domain at post-treatment. Substantially less adverse events were reported for MoBa compared to CBT. These results suggest the feasibility and acceptability of an algorithm-based modular psychotherapy complementing CBT in depressed patients with psychiatric comorbidities and early trauma. While initial evidence of efficacy was observed, potential clinical advantages and interindividual heterogeneity in treatment outcomes will have to be investigated in fully powered confirmation trials.

Impact of the Integrated Program of Transdiagnostic Treatment and Parent Education on the Social Anxiety of Female Students.

OBJECTIVE: The objective of this study was to assess the efficacy of the combined program of transdiagnostic treatment and parent education in reducing social anxiety among female students. METHODOLOGY:  This descriptive cross-sectional study was conducted among all female elementary school students in Bandar Abbas, Iran, during the academic year 2022-2023. The social phobia questionnaire was given to all female students in grades three to six to assess individuals in terms of the social anxiety disorder (SAD) variable. We used the social anxiety scale developed by Leibovitz as the questionnaire in this investigation. This self-assessment questionnaire was designed for individuals aged 18 and above. It consists of 24 statements, divided into two subscales: performance anxiety (13 statements) and social settings (11 statements). Each item is individually assessed for fear intensity on a scale of 0 to 3, ranging from no to extreme. Similarly, avoidance behavior is evaluated on a scale of 0 to 3, representing the frequency ranging from never to always. RESULTS:  The mean general anxiety levels among both groups (students vs. parents) during the pre-test were similar (48.06 ± 4.39 vs. 48.06± 4.1). However, in the post-test, the mean of the experimental groups was lower than that of the pre-test (32.13 ± 3.77 vs. 47.2 ± 3.6). The normality assumption for the pre-test and post-test variables of generalized anxiety was verified with a significance level over 0.05 (p ≥ 0.05). CONCLUSION: The findings demonstrated that the integrated meta-diagnostic treatment program for parents had a more pronounced effect on alleviating their social anxiety in comparison to students. These findings imply that if parents possess a comprehensive understanding of the factors contributing to their children's anxiety, it will significantly enhance their ability to mitigate their child's social anxiety.

Randomized controlled trial investigating web-based, therapist delivered eye movement desensitization and reprocessing for adults with suicidal ideation.

Introduction: Promising preliminary evidence suggests that EMDR may reduce suicidal ideation (SI) when used to treat Major Depressive Disorder, Posttraumatic Stress Disorder, and trauma symptoms in the context of acute mental health crises. EMDR has never been tested specifically for treating SI, and there is a lack of data regarding the safety and effectiveness of web-based, therapist-delivered EMDR in populations with known SI. The primary objective of this study was to investigate the impact of web-based, therapist-delivered EMDR, targeting experiences associated with suicidal thinking. Secondary objectives included examining the effect of EMDR treatment on symptoms of depression, anxiety, posttraumatic stress, emotional dysregulation, and dissociation, as well as safety and attrition. Methods: This randomized control trial (ClinicalTrials.gov ID number: NCT04181047) assigned adult outpatients reporting SI to either a web-based EMDR intervention or a treatment as usual (TAU) group. TAU included primary and mental health services available within the Canadian public health system. Participants in the EMDR group received up to 12 web-based EMDR desensitization sessions, delivered twice weekly during the COVID-19 pandemic (2021-2023). The Health Research Ethics Board at the University of Alberta approved the protocol prior to initiation of data collection for this study (protocol ID number: Pro00090989). Results: Forty-two adult outpatients received either EMDR (n=20) or TAU (n=22). Participants reported a high prevalence of early onset and chronic SI, and there was a high rate of psychiatric comorbidity. In the EMDR group, median SI, depression, anxiety, and posttraumatic symptom scale scores decreased from baseline to the four month follow-up. In the TAU group, only the median SI and posttraumatic symptom scale scores decreased from baseline to four month follow up. Although sample size precludes direct comparison, there were numerically fewer adverse events and fewer dropouts in the EMDR group relative to the TAU group. Conclusion: Study results provide promising preliminary evidence that web-based EMDR may be a viable delivery approach to address SI. In this complex population, a short treatment course was associated with reductions of SI and other symptoms across multiple diagnostic categories. Further investigation is warranted to verify and extend these results. Clinical Trial Registration: https://clinicaltrials.gov/study/NCT04181047?id=NCT04181047&rank=1, identifier NCT04181047.

Comparing the effectiveness of transdiagnostic treatment with acceptance and commitment therapy on emotional disorders, rumination, and life satisfaction in patients with irritable bowel syndrome: a randomized clinical trial.

OBJECTIVE: The present study was conducted to compare the effectiveness of transdiagnostic treatment (UP) with the acceptance and commitment therapy (ACT) on the emotional disorders, rumination, and life satisfaction in the patients with irritable bowel syndrome (IBS). METHOD: The present study was a randomized clinical trial with a pre-test and post-test design. Between the winter of 2021 and the end of spring 2022, Taleghani Hospital in Tehran received referrals from the statistical population of IBS patients. Of them, 30 individuals (15 in each group) were chosen by convenience sampling and then randomly allocated to groups. UP (It is emotion-based and intervenes in comorbid symptoms), and ACT treatments were provided to the participants online. The participants in the UP and ACT groups received the desired treatments in eight weekly sessions of 45-60 min. RESULTS: There was no significant difference between UP pre-test and ACT regarding depression, anxiety, rumination, and life satisfaction (P > 0.05). There was no significant difference between UP and ACT post-test in terms of depression, rumination, and life satisfaction (P > 0.05), but due to anxiety, their difference was significant (P < 0.05). Besides, there was a significant difference between pre-test and post-test phases of UP and ACT regarding depression, anxiety, and rumination (P < 0.05). Still, they had no significant difference regarding life satisfaction (P > 0.05). CONCLUSION: Therefore, it is suggested that specialists use UP and ACT as effective psychological treatments for the emotional symptoms of IBS patients to improve psychological symptoms.

Unified Protocol vs Trauma-Focused Cognitive Behavioral Therapy Among Adolescents With PTSD.

Harmful consequences of COVID-19, such as prolonged quarantine, lack of social contact, and especially loss of parents or friends, can negatively impact children and adolescents' mental health in diverse ways, including engendering posttraumatic stress symptoms. Our study is the first to compare the transdiagnostic Unified Protocol for the Treatment of Emotional Disorders in Adolescents (UP-A; Ehrenreich et al., 2009; Ehrenreich-May et al., 2017) with Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) in terms of outcomes related to PTSD symptoms (COVID-19-related vs. COVID-19 unrelated PTSD) and comorbid symptoms (i.e., anxiety, depression) and other measures (i.e., emotion regulation, self-injury, anger). Individuals diagnosed with PTSD were randomly assigned to the UP-A (n = 46) or TF-CBT group (n = 47), administered the SCID-5 and a battery of measures and followed up posttreatment and then after 3, 6, and 9 months. Ninety-three adolescents with PTSD were enrolled, 45% boys and 61% COVID-19-related PTSD. We adopted an intention-to-treat approach. At the initial post-intervention assessment, except for emotion regulation and unexpressed angry feelings, in which UP-A participants reported greater reductions, no significant differences in other variables were secured between the UP-A and TF-CBT. However, at follow-up assessments, the UP-A evidenced significantly better outcomes than TF-CBT. We found support for the UP-A compared with TF-CBT in treating adolescents with PTSD, regardless of COVID-19-related PTSD status, in maintaining treatment effectiveness over time.

Early indicators of response to transdiagnostic treatment of pediatric anxiety and depression.

BACKGROUND: Pediatric anxiety and depression are prevalent, impairing, and highly comorbid. Available evidence-based treatments have an average response rate of 60%. One path to increasing response may be to identify likely non-responders midway through treatment to adjust course prior to completing an episode of care. The aims of this study, thus, were to identify predictors of post-intervention response assessing (a) mid-treatment symptom severity, (b) session-by-session treatment process factors, and (c) a model optimizing the combination of these. METHOD: Data were drawn from the treatment arm (N = 95, ages 8-16) of a randomized transdiagnostic intervention trial (Msessions = 11.2). Mid-point measures of youth- and parent-reported anxiety and depression were collected, and therapists rated homework completion, youth and parent engagement, and youth therapeutic alliance at each session. Logistic regression was used to predict response on the Clinical Global Impression Improvement Scale (CGI-I ≤2) rated by independent evaluators masked to treatment condition. RESULTS: Mid-point symptom measures were significant predictors of treatment response, as were therapist-ratings of youth and parent engagement, therapeutic alliance, and homework completion. Therapist ratings were significant when tested as mean ratings summing across the first eight sessions of treatment (all ps < .004) and at individual session points (all ps <0.05). A combined prediction model included youth-reported anxiety, parent-reported depression, youth engagement at Session 2, and parent engagement at Session 8. This model correctly classified 76.5% of youth as non-responders and 91.3% as responders at post-treatment (Nagelkerke R2 = .59, χ2 (4, 80) = 46.54, p < .001). CONCLUSION: This study provides initial evidence that response to transdiagnostic intervention for pediatric anxiety and depression may be reliably predicted by mid-point. These data may serve as foundational evidence to develop adaptive treatment strategies to personalize intervention, correct treatment course, and optimize outcomes for youth with anxiety and depression.

Blended smartphone intervention for patients in opioid maintenance treatment in Iran: protocol for a randomized controlled trial.

BACKGROUND: The pattern of substance use in Iran is characterized by a high prevalence of opioid use and opioid use disorder (OUD). Although opioid maintenance therapy (OMT) has been introduced in Iran, approximately 50% of people with opioid use disorder remain unreached. Moreover, psychosocial treatment of OUD and common mental health symptoms during OMT is limited. Digital interventions have been shown to improve psychological distress, depression, anxiety, and post-traumatic stress disorder symptoms. In addition, providing psychoeducation and risk reduction counseling to prevent communicable diseases like HIV and infectious hepatitis is common via the Internet. However, despite these promising advances, no smartphone intervention in OMT has been investigated for the treatment of OUD and common comorbid mental health symptoms. OBJECTIVE: We examine the effectiveness of adding a blended smartphone intervention based on community reinforcement approach, motivational interviewing- and cognitive behavioral therapy compared to OMT as usual that aims to improve OMT outcomes and addresses common mental health symptoms in OMT patients in Iran. METHOD: Adults with opioid dependence entering 8 treatment centers in Tehran, Iran will be randomly assigned to receive either OMT plus a smartphone intervention or OMT as usual. The primary outcomes will be the percentage of negative urine tests for illicit, non-prescribed use of opioids (opium, heroin, tramadol) and treatment retention. Secondary outcomes will include the longest period of abstinence from the illicit, non-prescribed use of opioids (opium, heroin, and tramadol) confirmed by urine samples, changes in communicable disease risk-taking behaviors, changes in stress and common mental health symptoms, and client satisfaction. Data analysis will follow the intention-to-treat principle and employ (generalized) linear mixed models. DISCUSSION: This study will provide substantial knowledge for designing effective blended interventions for OUD. Moreover, it will investigate if treatment retention and OMT-related outcomes and common mental health symptoms can be improved by adding a smartphone intervention to OMT.

Comparing the unified protocol for transdiagnostic treatment of emotional disorders to prolonged exposure for the treatment of PTSD: Design of a non-inferiority randomized controlled trial.

Background: Prolonged Exposure (PE), a trauma-focused therapy, is one of the most efficacious treatments available for PTSD. However, many people with PTSD do not lose their diagnosis following delivery of PE. The Unified Protocol (UP) for Transdiagnostic Treatment of Emotional Disorders is a non-trauma focused treatment that may offer an alternative treatment for PTSD. Methods: This paper describes the study protocol for IMPACT, an assessor-blinded randomized controlled trial that examines the non-inferiority of UP relative to PE for participants who meet DSM-5 criteria for current PTSD. One hundred and twenty adult participants with PTSD will be randomized to receive either 10 × 90-min sessions of UP or PE with a trained provider. The primary outcome is severity of PTSD symptoms assessed by the Clinician Administered PTSD Scale for DSM-5 (CAPS-5) at post-treatment. Discussion: While evidence-based treatments are available for PTSD, high levels of treatment dropout and non-response require new approaches to be tested. The UP is based on emotion regulation theory and is effective in treating anxiety and depressive disorders, however, there has been limited application to PTSD. This is the first rigorous study comparing UP to PE in a non-inferiority randomized controlled trial and may help improve clinical outcomes for those with PTSD. Trial registration: This trial was prospectively registered with the Australian New Zealand Clinical Trials Registry, Trial ID (ACTRN12619000543189).

PsicAP transdiagnostic protocol of group cognitive-behavioral training for emotional disorders in Dominican Republic: a randomized controlled trial protocol.

Emotional disorders (ED) such as anxiety, depression and somatization are extremely prevalent disorders that can affect an individual's quality of life and functionality. Primary Health Care (PHC) is the first place to identify most patients with these conditions. Mental health services in the Dominican Republic, as well as in Latin America and the Caribbean in general, are unable to provide appropriate care for most people with mental disorders. Using evidence-based treatment protocols is also crucial to make progress in helping people with ED. The PsicAP project is a group intervention that uses a transdiagnostic approach and is grounded in cognitive-behavioral techniques. The program is implemented in 7 group sessions, each lasting for one and a half hours. The program has been shown to be effective in reducing clinical symptoms, dysfunction, and in improving quality of life. It is also a non-time-intensive, low-cost treatment that is helpful for addressing EDs in a PHC context. The objective is to bring psychological treatments into PHC facilities of Dominican Republic, making them more accessible for a larger amount of the population.

PSICE Project Protocol: Evaluation of the Unified Protocol for Transdiagnostic Treatment for Adolescents with Emotional Symptoms in School Settings / El protocolo del Proyecto PSICE: evaluación del protocolo unificado transdiagnóstico para adolescentes con síntomas emocionales en contextos educativos

Background: The aim of the PSICE (Evidence-based Psychology in Educational Contexts) Project is to examine the effectiveness of the Unified Protocol for Transdiagnostic Treatment of Adolescents (UP-A) with symptoms of anxiety and depression in school settings. The goal is to prevent emotional problems and to improve adolescents’ socioemotional adjustment, learning processes, and academic performance. Method: A randomized controlled trial with two groups will be performed: active control (progressive relaxation training) and experimental (UP-A). After screening, participants with subclinical emotional symptomatology will be selected for pre- and post-test evaluation and follow-up at 6, 12, and 18 months. Results: The impact of different indicators at behavioral, cognitive, affective, social and academic functioning levels will be analyzed, as well as their effects in the short, medium and long term. Conclusions: Examining the effectiveness of the UP-A in the Spanish educational context will, among other things, provide data for informed decision-making in the field of educational psychology. In addition, it will ensure that such interventions, using standardized protocols, are accessible to a large population at such an important stage of human development as adolescence. The PSICE project will provide leadership and guidance on the importance of psychology in schools. (AU)

El proyecto PSICE proporcionará liderazgo y orientación sobre la importancia de la Psicología en el contexto educativo. (AU)

Transdiagnostic treatment of depression and anxiety: a meta-analysis.

BACKGROUND: In the past 10 years an increasing number of randomised trials have examined the effects of transdiagnostic treatments of patients with depression or anxiety. We conducted the first comprehensive meta-analysis of the outcomes of this emerging field. METHODS: We used the searches in PubMed, PsychINFO, Embase and the Cochrane library of an existing database of randomised trials of psychological interventions for depression to identify studies comparing a transdiagnostic treatment of patients with depression or anxiety with a control group (deadline 1 January 2022). We conducted random-effects meta-analyses and examined the effects on depression and anxiety at the short and longer term. RESULTS: We included 45 randomised controlled trials with 51 comparisons between a psychotherapy and a control group and 5530 participants. Thirty-five (78%) studies were conducted in the last 10 years. The overall effect size was g = 0.54 (95% CI 0.40-0.69; NNT = 5.87), with high heterogeneity (I2 = 78; 95% CI 71-83), and a broad PI (-0.31-1.39). The effects remained significant in a series of sensitivity analyses, including exclusion of outliers, adjustment for publication bias, for studies with low risk of bias, and in multilevel analyses. The results were comparable for depression and anxiety separately. At 6 months after randomisation the main effects were still significant, but not at 12 months, although the number of studies was small. CONCLUSIONS: Transdiagnostic treatments of patients with depression or anxiety are increasingly examined and are probably effective at the short term.

Evidence that a novel transdiagnostic eating disorder treatment reduces reward region response to the thin beauty ideal and high-calorie binge foods.

BACKGROUND: Findings from brain imaging studies with small samples can show limited reproducibility. Thus, we tested whether the evidence that a transdiagnostic eating disorder treatment reduces responsivity of brain valuation regions to thin models and high-calorie binge foods, the intervention targets, from a smaller earlier trial emerged when we recruited additional participants. METHODS: Women with DSM-5 eating disorders (N = 138) were randomized to the dissonance-based body project treatment (BPT) or a waitlist control condition and completed functional magnetic resonance imaging (fMRI) scans assessing neural response to thin models and high-calorie foods at pretest and posttest. RESULTS: BPT v. control participants showed significantly greater reductions in responsivity of regions implicated in reward valuation (caudate) and attentional motivation (precuneus) to thin v. average-weight models, echoing findings from the smaller sample. Data from this larger sample also provided novel evidence that BPT v. control participants showed greater reductions in responsivity of regions implicated in reward valuation (ventrolateral prefrontal cortex) and food craving (hippocampus) to high-calorie binge foods v. low-calorie foods, as well as significantly greater reductions in eating disorder symptoms, abstinence from binge eating and purging behaviors, palatability ratings for high calorie foods, monetary value for high-calorie binge foods, and significantly greater increases in attractiveness ratings of average weight models. CONCLUSIONS: Results from this larger sample provide evidence that BPT reduces valuation of the thin ideal and high-calorie binge foods, the intervention targets, per objective brain imaging data, and produces clinically meaningful reductions in eating pathology.

The Effectiveness of Transdiagnostic Treatment Program on Clinical Symptoms and Emotion Regulation in Girls Adolescents with Premenstrual Syndrome.

Background: Premenstrual Syndrome (PMS) is the experience of some physical and psychological symptoms periodically in the last days of the menstrual cycle that interferes with academic, social and family functioning. We aimed to evaluate the effectiveness of Transdiagnostic Treatment Program (TTP) on clinical symptoms and emotion regulation in girl's adolescents with PMS. Methods: This experimental trial study was carried out on 32 girls adolescents with PMS referred to two medical centers located in Tehran, Iran from Mar 21, 2019, to Oct. The patients randomized in 2 groups, 1-intervention (n=16, 8 sessions, 90-minute weekly) and 2-control (n=10).The PMS Screening Tool (PSST) and Emotion Regulation Questionnaire (ERQ) before and after treatment were filled out by participant. The SPSS software and P<0.05 considered for data analysis and as significant levels respectively. Results: The study sample was 32 girls adolescents with PMS (mean age intervention and control were 16.30±2.02 and 16.40±1.6, P=0.915). The score of two questionnaires, PSST (symptom, effect) and ERQ (cognitive reappraisal, suppression) between two groups in before treatment were the same. After intervention the change of variable symptom (-1.05 vs -0.02, P<0.001), effect (-0.53 vs -0.04, P<0.001), cognitive reappraisal (0.67 vs 0.02, P<0.001) and suppression (-0.64 vs -0.07, P<0.001) were significant between two groups. Conclusion: TTP is an effective technique for controlling clinical symptoms and emotion regulation in girl's adolescents with PMS.

Effectiveness of the Unified Barlow Protocol (UP) and neuropsychological treatment in cancer survivors for cognitive impairments: study protocol for a randomized controlled trial.

BACKGROUND: Cancer survivors frequently develop cognitive impairment, which negatively affects their quality of life and emotional well-being. This study compares the effectiveness of a well-established treatment (neuropsychological treatment) with the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP) to reduce these cognitive deficits and evaluate the effect of both treatments on anxiety-depressive symptoms and the quality of life of cancer survivors. METHODS: A three-arm, randomized superiority clinical trial with a pre-post and repeated follow-up measures intergroup design using a 1:1:1 allocation ratio will be performed. One hundred and twenty-three cancer survivors with mild to moderate cognitive impairment will be randomly assigned to one of the study interventions: a cognitive rehabilitation intervention group, an intervention group with UP intervention, or a control group on the waiting list. The primary outcome is to observe a significant improvement in cognitive function in both intervention groups and a significant decrease in emotional impairments in comparison with the waitlist group. Improvements in anxiety, depression, and quality of life are also expected as secondary outcomes. These results will be maintained at 6 months of follow-up. DISCUSSION: The aim of this trial is to test the efficacy of the UP intervention in reducing cognitive deficits in breast cancer survivors. The results of this trial may be useful in reducing the presence of cognitive problems in cancer survivors and improving their emotional state and quality of life.

Group Mindfulness-Integrated Cognitive Behavior Therapy (MiCBT) Reduces Depression and Anxiety and Improves Flourishing in a Transdiagnostic Primary Care Sample Compared to Treatment-as-Usual: A Randomized Controlled Trial.

Objectives: This study investigated the effectiveness of a group-based 8-week intervention, Mindfulness-integrated Cognitive Behavior Therapy (MiCBT), to decrease psychological distress and increase wellbeing in a heterogeneous population in primary health care. MiCBT focuses on the importance of interoception and its interaction with cognition in emotional experience. These interactions are represented in the co-emergence model of reinforcement, in which non-reactivity (equanimity) to interoceptive signals facilitates adaptive behavior. Methods: Participants (n = 125, aged 20-72) were randomized to two groups (MiCBT), and treatment-as-usual (TAU). Outcomes were assessed at pre-, mid-, and post-intervention and at 6-month follow-up. The primary outcome was psychological distress, measured by the Depression, Anxiety and Stress Scale (DASS-21). Secondary outcome measures were the Kessler Psychological Distress Scale-10 (K10), Satisfaction with Life Scale (SWLS), and Flourishing Scale (FS). Mediator or process measures of interoceptive awareness, metacognitive awareness (decentering), equanimity, and social functioning were included to investigate putative mediators. Results: The MiCBT intervention significantly reduced DASS-21 scores at mid and post-treatment and the gains were maintained at 6-month follow-up (p < 0.0001, d = 0.38). Flourishing scores also showed significant improvement post-treatment and at 6-month follow-up (d = 0.24, p < 0.0001). All measures selected showed a similar pattern of positive change, with the exception of the SWLS, which failed to reach significance. Mediation analysis suggested equanimity to be the most influential mediator of the primary outcome. Conclusions: The results support the effectiveness of MiCBT in creating rapid and sustainable reduction of psychological distress and improvement in flourishing in a primary mental health care setting with heterogenous groups. These promising results support the scaled-up implementation of this intervention.

Ambivalence resolution in the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders: An exploratory case study.

Patient ambivalence towards change is a central therapeutic target in the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP). However, we do not know if and how patients resolve ambivalence across the sessions and modules of the UP. Previous studies have identified two types of ambivalence resolution-dominance and negotiation-and different patterns of resolution for recovered and unchanged cases. Objectives: This exploratory single case study aimed to describe the frequency of observed ambivalence resolution strategies across UP sessions and evaluate the impact of distinct ambivalence resolution strategies on ambivalence. Method: Sixteen sessions of a recovered case were coded with observational measures of ambivalence and ambivalence resolution. Results: Observed ambivalence significantly decreased; dominance remained highly frequent across sessions, and negotiation increased from the beginning to the middle phase of treatment but not from the middle to the final phase. Negotiation was significantly associated with ambivalence reduction. Conclusion: The progression of ambivalence resolution strategies differed from previous studies with distinct therapeutic approaches; promoting negotiation between the different parts of the client's inner conflict across the whole therapy may be valuable in dealing with patient ambivalence in UP treatment.
