AN OPEN TRIAL OF EMOTION REGULATION THERAPY FOR GENERALIZED ANXIETY DISORDER AND COOCCURRING DEPRESSION

The impact of immersive virtual reality meditation for depression and anxiety among inpatients with major depressive and generalized anxiety disorders

Background

Mindfulness-Based Cognitive Therapy (MBCT) is a non-pharmacological approach to alleviating depression and anxiety. While technology based MBCT is a standardized cost-effective approach, there have been concerns about its feasibility and effectiveness in clinical settings.

Aims

The purpose of this study was to investigate the longitudinal relationship between improved emotional regulation resulting from participation in Immersive Virtual Reality Meditation (IVRM) and Major Depressive Disorder (MDD) and Generalized Anxiety Disorder (GAD) as monitored by electrocardiogram.

Methods

This study was a longitudinal single-arm clinical trial in which the intervention was conducted three times a week for 10 weeks at a behavioral health unit in a community hospital (n = 26). We measured Coherence Achievement Score (CAS), depression, and anxiety. The relationships between CAS, anxiety, depression, and covariates were analyzed using a Generalized Estimated Equation (GEE).

Results

The findings of our study provide evidence that the CAS scores indicative of emotional regulation function after IVRM participation were associated with a reduction in depression and anxiety.

Conclusion

Among the many technology-based complementary health care interventions that are available to reduce depression and anxiety, IVRM program use increases emotional regulatory function and decrease depression and anxiety.

Improving emotion regulation ability after brain injury: A systematic review of targeted interventions

Emotion dysregulation is a common sequela after a brain injury, and it can have serious negative consequences for individuals, families, and the community. A systematic review of the literature was conducted to identify and evaluate interventions designed to improve emotion regulation ability in adults with acquired brain injury. Studies were identified on ProQuest, PsycInfo, ScienceDirect, Scopus, and Web of Science; last searched on 3 August 2023. A review protocol was prospectively registered on PROSPERO (CRD42020218175). Risk of bias was assessed using the Cochrane Risk-of-Bias tool (version 2). Sixteen studies were included in the review comprising one case series, five pilot studies, four pre-post studies, and six RCTs. There was a total of 652 participants across studies. Fourteen of the sixteen studies reported statistically significant improvements in at least one emotional functioning variable. Ten studies reported medium-large effect sizes. Limitations included inconsistency in the measurement, reporting of intervention outcomes and processes. Future directions are discussed.

A multi-method assessment of emotional processes predicting longitudinal anxiety symptom trajectories in an adolescent clinical sample

Objective

Emotion recognition, reactivity, and regulation are important in the development and maintenance of anxiety disorders. Whether and how these processes differentiate between different trajectories in anxiety remain unclear. The current study examined emotional processes as prospective predictors of anxiety symptom trajectories in psychiatrically hospitalized youth.

Method

Participants were 180 adolescents (M age = 14.89; SD = 1.35) from a psychiatric inpatient unit. At index hospitalization, participants completed a behavioral task assessing facial emotion recognition, and self-report measures of emotion dysregulation and reactivity. They completed a self-report measure on anxiety symptoms at baseline and 3, 6, 12, and 18 months post-discharge. Latent growth curve analysis was conducted to identify subgroups of individuals based upon their trajectory of anxiety symptoms across 18-months. ANOVAs were used to examine subgroup differences in emotional processing variables.

Results

Three distinct trajectories were identified, a stable moderate-to-high anxiety group, a group with moderate-to-high anxiety at baseline with symptom improvement over time, and a group characterized by relatively stable low-to-moderate anxiety throughout the study. The two initially moderate-to-high anxiety groups scored higher for emotion dysregulation and emotion reactivity at baseline compared to the low-to-moderate anxiety group. Emotion regulation difficulties relating to emotional non-acceptance were higher for the stable moderate-to-high anxiety group than for the moderate-to-high anxiety group that experience symptom improvement over time.

Conclusions

These findings may have clinical implications for discharge planning. Future studies should explore emotion regulation with a focus on non-acceptance of one's emotional experiences as a potential target of intervention in individuals with elevated anxiety.

Alterations in neural circuit dynamics between the limbic network and prefrontal/default mode network in patients with generalized anxiety disorder

BACKGROUND

Widespread functional alterations have been implicated in patients with generalized anxiety disorder (GAD). However, most studies have primarily focused on static brain network features in patients with GAD. The current research focused on exploring the dynamics within functional brain networks among individuals diagnosed with GAD.

METHODS

Seventy-five participants were divided into patients with GAD and healthy controls (HCs), and resting-state functional magnetic resonance imaging data were collected. The severity of symptoms was measured using the Hamilton Anxiety Scale and the Patient Health Questionnaire. Co-activation pattern (CAP) analysis, centered on the bed nucleus of the stria terminalis, was applied to explore network dynamics. The capability of these dynamic characteristics to distinguish between patients with GAD and HCs was evaluated using a support vector machine.

RESULTS

Patients with GAD exhibited disruptions in the limbic-prefrontal and limbic-default-mode network circuits. Particularly noteworthy was the marked reduction in dynamic indicators such as occurrence, EntriesFromBaseline, ExitsToBaseline, in-degree, out-degree, and resilience. Moreover, these decreased dynamic features effectively distinguished the GAD group from the HC in this study.

CONCLUSIONS

The current findings revealed the underlying brain networks associated with compromised emotion regulation in individuals with GAD. The dynamic reduction in connectivity between the limbic-default mode network and limbic-prefrontal networks could potentially act as a biomarker and therapeutic target for GAD in the future.

Emotion Dysregulation and E-Cigarette Expectancies among College Student E-Cigarette Users

Background: E-cigarette outcome expectancies (i.e., beliefs about the expected consequences of e-cigarette use) are a key factor in motivating use. Emotion regulation difficulties have demonstrated significant associations with outcome expectancies; however, there has yet to be an examination of associations between specific emotion regulation difficulties and specific e-cigarette outcome expectancies, which could serve as targets for intervention efforts. Therefore, the current study sought to examine the unique predictive ability of specific emotion regulation difficulties in terms of e-cigarette outcome expectancies. Methods: Participants were 116 college student e-cigarette users (Mage = 19.72, SD = 1.88; 71.6% female) who completed self-report questionnaires for course credit. Results: Greater difficulties engaging in goal-directed behavior when experiencing negative emotions and fewer difficulties accessing effective emotion regulation strategies were associated with positive reinforcement outcome expectancies. Greater emotion regulation difficulties in general were also associated with negative reinforcement outcome expectancies, though there were no significant individual predictors. Conclusion: These results suggest that greater emotion regulation difficulties are associated with mood-related e-cigarette outcome expectancies, and targeting emotion regulation difficulties, particularly difficulty engaging in goal-directed behavior when upset, may be useful to incorporate into intervention efforts.

A randomized controlled trial comparing two doses of emotion regulation therapy: Preliminary evidence that gains in attentional and metacognitive regulation reduce worry, rumination, and distress

BACKGROUND

Emotion regulation therapy (ERT) promotes resilience in distress disorders by strengthening attentional and metacognitive capacities. Regulation skills are presented with the goal of ameliorating the perseverative negative thinking (PNT) that characterizes these disorders. This study tested ERT in a randomized controlled trial comparing the effectiveness of 16-session (ERT16) versus 8-session (ERT8) doses.

METHOD

Patients (N = 72) endorsing elevated worry and/or rumination and meeting diagnostic criteria for a distress disorder were randomized to ERT8 or ERT16. PNT, anxiety/depressive symptoms, functioning/quality of life, and treatment mechanisms (attention shifting, attention focusing, decentering, reappraisal) were measured at pre, mid, and post treatment. Clinical symptom severity was also assigned via diagnostic interview at each timepoint.

RESULTS

ERT produced significant improvements across outcomes. ERT16 showed an advantage over ERT8 for distress disorder severity, worry, rumination, and attention shifting from pre-post treatment. Changes in ERT treatment mechanisms mediated changes in clinical improvement.

CONCLUSION

These findings provide evidence of the effectiveness of two doses of ERT in reducing PNT and distress through improvements in regulation skills.

In situ fNIRS measurements during cognitive behavioral emotion regulation training in rumination-focused therapy: A randomized-controlled trial

Repetitive negative thinking (RNT), including rumination, plays a key role in various psychopathologies. Although several psychotherapeutic treatments have been developed to reduce RNT, the neural correlates of those specific treatments and of psychotherapy in general are largely unknown. Functional near-infrared spectroscopy (fNIRS) offers the potential to investigate the neural correlates of psychotherapeutic techniques in situ. Therefore, in this study we investigated the efficacy and neural correlates of a fNIRS adapted Mindfulness-based Emotion Regulation Training (MBERT) for the treatment of depressive rumination in 42 subjects with major depressive disorder (MDD) in a cross-over designed randomized controlled trial. Using psychometric measures, subjective ratings and fNIRS, we analyzed in situ changes in depressive symptom severity, ruminative thoughts and cortical activity in the Cognitive Control Network (CCN). Our results show that MBERT is effective in treating depressive symptoms and rumination. On a neural level, we found consistently higher cortical activation during emotion regulation training compared to control trials in the bilateral inferior frontal gyrus (IFG) and dorsolateral prefrontal cortex (DLPFC). Furthermore, cortical oxygenation decreased from session to session in the bilateral DLPFC. The relevance of the results for the psychotherapeutic treatment of MDD as well as further necessary investigations are discussed.

Emotional Dysregulation is the Core Problem in Psychopathological Manifestations

The established opinion is that emotions are the gift given to us by nature in order to help us connect with other people. They are constantly generated, usually by stimuli in our intrapersonal as well as in external world. Problems raised in our relationships initiate emotions to help us to fix those problems. Almost all forms of human psychopathology are associated with dysregulated emotions. The failure to apply appropriate cognitive, attentive, and behavioural regulatory strategies is the core for emotion dysregulation. The brain regulates emotions through a biological mechanism. Emotions rise in intensity, peak, and then go flat once the emotion adaptive action tendency has been expressed. The aim of the therapist is to help clients express, face, and regulate their emotions, and to channel these emotions into healthy actions. The idea of this article is to present contributions from both affective neuroscience and psychotherapy in order to explain the ways how our emotions become dysregulated in life and how they can become regulated through psychotherapy.

Enhancing emotion regulation

BACKGROUND

Emotion regulation (ER) refers to the process of modulating an affective experience or response. Objectives: This is a systematic review of the research on therapist methods to facilitate patient ER, including affect-focused, experiential methods that aim to enhance immediate patient emotion regulation, and structured psychoeducation, skills training in ER.

METHOD

A total of 10 studies of immediate and intermediate outcomes of emotion regulation methods were examined. A total of 38 studies were included in the meta-analysis of distal treatment effects on emotion regulation.

RESULTS

In eight studies with 84 clients and 33 therapists, we found evidence of positive intermediate outcomes for affect-focused therapist methods and interpretations. A meta-analysis of 26 studies showed that the average effect size of ER methods from pre- to post-treatment was large (g = 0.82).

CONCLUSIONS

Both affect-focused and structured skill training are associated with distal improvements in emotion regulation. When working with ER in psychotherapy, therapists must consider how patients' cultural backgrounds inform display rules, as well as what might be considered adaptive or maladaptive. The article concludes with training implications and therapeutic practices based on the research evidence.

A randomized controlled trial of emotion regulation therapy for cancer caregivers: A mechanism-targeted approach to addressing caregiver distress

BACKGROUND

Caregivers of patients with cancer play a crucial role in the health of the person they care for, and in the healthcare system at large. Family caregivers receive minimal support, despite being at greater risk for anxiety and depression than patients themselves. Cognitive behavioral therapy (CBT), an effective therapy for anxiety and depression, has shown mixed efficacy when delivered to cancer caregivers. Emotion Regulation Therapy (ERT), a contemporary CBT, may uniquely target processes underlying distress associated with caregiving. Therefore, we adapted both CBT and ERT to target the needs of caregivers (i.e., CBT-C and ERT-C) and are conducting a multi-site randomized trial to examine the comparative efficacy of these interventions.

METHODS

Family cancer caregivers (n = 200) reporting distress related to caregiving are recruited from two academic cancer centers and randomly assigned to either ERT-C or CBT-C. Caregivers in both interventions engage in eight weekly one-hour sessions by videoconference with a trained interventionist. Caregiver participants complete study assessments at baseline, post-treatment, 3-and 6-months follow-up. Patients of each caregiver can also enroll in the study and complete assessments at baseline and 3-months follow-up. Outcome measures include psychosocial constructs such as anxiety, depression, quality of life, as well as proposed mechanistic constructs and salivary markers of stress and inflammation.

CONCLUSIONS

The results of this study will advance the science of caregiving interventions in cancer by addressing a critical gap in our ability to mitigate anxiety and depression in caregivers, as well as further our understanding of how these changes may influence patients' outcomes.

Review of Perioperative Music Medicine: Mechanisms of Pain and Stress Reduction Around Surgery

Clinical-experimental considerations and an approach to understanding the autonomic basis of improved surgical outcomes using Perioperative Music Medicine (PMM) are reviewed. Combined surgical, psycho-physiological, and experimental perspectives on Music Medicine (MM) and its relationship to autonomic nervous system (ANS) function are discussed. Considerations are given to the inter-related perioperative effects of MM on ANS, pain, and underlying vagal and other neural circuits involved in emotional regulation and dysregulation. Many surgical procedures are associated with significant pain, which is routinely treated with post-operative opioid medications, which cause detrimental side effects and delay recovery. Surgical trauma shifts the sympathetic ANS to a sustained activation impairing physiological homeostasis and causing psychological stress, as well as metabolic and immune dysfunction that contribute to postoperative mortality and morbidity. In this article, we propose a plan to operationalize the study of mechanisms mediating the effects of MM in perioperative settings of orthopedic surgery. These studies will be critical for the implementation of PMM as a routine clinical practice and to determine the potential limitations of MM in specific cohorts of patients and how to improve the treatment.

Deconstructing emotion regulation in schizophrenia: The nature and consequences of abnormalities in monitoring dynamics

Prior studies implicate abnormalities at the identification, selection, and implementation stages of Gross' extended process model of emotion regulation in schizophrenia. However, it is unclear whether monitoring dynamics (i.e., emotion regulation maintenance, switching, and stopping), another critical component of the model, are also abnormal or what predicts those abnormalities. The current study evaluated switching (i.e., switching to a different emotion regulation strategy because the initial strategy was not effective) and stopping dynamics (i.e., terminating the implementation of an emotion regulation strategy) and their associated mechanisms using 6 days of ecological momentary assessment in 47 outpatients with schizophrenia or schizoaffective disorder (SZ) and 52 healthy controls (CN). Results indicated that individuals with SZ exhibited excessive switching between emotion regulation strategies and delayed stopping compared to CN, self-efficacy moderated group differences in stopping abnormalities, and switching and stopping abnormalities were associated with different patterns of state-level positive and negative symptoms in SZ. Findings may inform psychosocial emotion regulation therapies for SZ that could incorporate elements for monitoring dynamics and associated mechanisms.

Emotional Dysregulation in Preschoolers with Autism Spectrum Disorder-A Sample of Romanian Children

Emotional dysregulation problems seem to affect more than 80% of people with autism spectrum disorder (ASD) and may include irritability, aggressive behaviors, self-injury, and anxiety. Even though these types of problems are very common and affect the well-being of individuals with ASD, there are no objective assessment tools developed for this population and there are only a few intervention techniques meant to address these symptoms. This study investigates the feasibility of using off-the-shelf wearable devices to accurately measure heart rate, which has been associated with emotional dysregulation, and to test the effectiveness of functional communication training in reducing the emotional outburst in preschoolers with ASD. We used a single-case experiment design with three preschoolers with ASD to test if the duration of the emotional outburst and the elevated heart rate levels can be reduced by using functional communication training. Our results show that for two of the participants, the intervention was effective in reducing the duration of behaviors associated with emotional outburst, and that there were significant differences between baseline and intervention phase in terms of heart rate levels. However, our results are inconclusive regarding the association between elevated heart rates and the occurrence of the emotional outburst. Nevertheless, more research is needed to investigate the use of off-the-shelf wearable devices in predicting challenging behaviors in children with ASD.

Moderators and mediators of emotion regulation therapy for psychologically distressed caregivers of cancer patients: secondary analyses from a randomized controlled trial

BACKGROUND

Being an informal caregiver (IC) of a cancer patient is often associated with psychological distress. We have recently, in a randomized controlled trial (RCT), demonstrated efficacy of Emotion Regulation Therapy for ICs (ERT-C), evidenced as lower levels of psychological distress. Such efficacy demonstration is important, but a crucial step in improving treatments for the IC population is the identification of moderators (i.e., for whom the treatment works) and mediators (i.e., the drivers of the detected effect).

MATERIAL AND METHODS

In a sample of 65 psychologically distressed ICs (combining participants who received immediate and delayed treatment in the RCT); we investigated age, gender, and homework completion as moderators of treatment outcome. Proposed mediators were derived from the ERT model and included mindfulness, emotion regulation dysfunction, decentering, and cognitive reappraisal.

RESULTS AND CONCLUSIONS

The strongest moderation effect was found for homework completion, predicting improvements on psychological distress. Correlational mediation analyses generally supported the ERT model. However, temporal precedence was only established for the association between decentering and worry, where a bidirectional relation was revealed. Homework thus emerged as an important aspect of ERT-C and, albeit a bidirectional relationship, changes in decentering may precede changes in worry. Future trials should ensure the robustness of these results, hone the specificity of process measures, and further investigate the causal timeline of change.

Emotion regulation therapy for cancer caregivers-an open trial of a mechanism-targeted approach to addressing caregiver distress

Informal caregivers (ICs) are integral to care provided to patients facing life-threatening or incurable illnesses. This responsibility causes considerable burden, as approximately one half of ICs report clinically significant symptoms of depression and/or anxiety that persist when left untreated. Psychosocial interventions containing efficacious treatment principles (e.g., cognitive behavior therapy [CBT]) show disappointing results in reducing anxiety and depression in ICs. This may reflect failure of these interventions to specifically target crucial mechanisms underlying the central feature of distress caused by the patient's illness-notably, perseverative negative thinking (PNT). Emotion Regulation Therapy (ERT) is an efficacious CBT developed to explicitly target mechanisms underlying PNT and the emotional concomitants that arise in response to stressful situations. This open trial was conducted to evaluate the acceptability and initial efficacy of ERT adapted to the experience of cancer ICs (ERT-C). Thirty-one ICs provided informed consent and completed eight weekly individual sessions of ERT-C. Participants completed self-report measures of depression and anxiety symptoms, PNT, emotion regulation deficits, and caregiver burden before and after treatment. ERT-C was well tolerated as indicated by 22 treatment completers and feedback provided in exit interviews. ICs demonstrated reduced depression and anxiety symptoms, PNT, and emotion regulation deficits with moderate to large effect sizes (Hedge's g range: 0.36-0.92). Notably, caregiver burden was not reduced but ICs expressed more ability to confront caregiving-related challenges. Findings offer promising but preliminary support for ERT-C as a conceptual model and treatment modality for distressed cancer ICs.

The Importance of Understanding Individual Differences of Emotion Regulation Abilities in 22q11.2 Deletion Syndrome

Chromosome 22q11.2 deletion syndrome (22q11DS) is characterised by a complex behavioural phenotype including anxiety, attention-deficit/hyperactivity disorder and psychosis. In the current study, we aimed at improving our understanding of the heterogeneity of behavioural characteristics in a group of 129 young people (aged 4-22) with a confirmed 22q11.2 microdeletion and 116 age and gender matched typically developing controls. Half the participants with 22q11DS had behaviour characterised by emotion dysregulation. A cluster analyses, of the participants with 22q11DS, revealed four groups characterised by intact emotion regulation; predominantly internalizing problems; both internalizing and externalizing problems; and predominantly externalizing difficulties. Importantly, it was found that young people with 22q11DS whose emotion dysregulation was characterised by externalizing problems had the poorest levels of functioning. As our understanding of 22q11DS improves, it is becoming increasingly clear that we need a better understanding of how individual differences and psychosocial factors contribute to, and interact with one another, to result in the observable individual differences in the 22q11DS behavioural phenotype.

Emotion regulation therapy for social anxiety disorder: a single case series study

BACKGROUND

Despite the vast majority of evidence indicating the efficacy of traditional and recent cognitive behaviour therapy (CBT) therapies in treating social anxiety disorder (SAD), some individuals with SAD do not improve by these interventions, particularly when co-morbidity is present.

AIMS

It is not clear how emotion regulation therapy (ERT) can improve SAD co-morbid with symptoms of generalized anxiety disorder (GAD) and depression. This study investigated this gap.

METHOD

Treatment efficacy was assessed using a single case series methodology. Four clients with SAD co-occurring with GAD and depression symptoms received a 16-session version of ERT in weekly individual sessions. During the treatment, self-report measures and clinician ratings were used to assess the symptom intensity, model-related variables, and quality of life, work and social adjustment of participants every other week throughout the treatment. Follow-up was also conducted at 1, 2 and 3 months after treatment. Data were analysed using visual analysis, effect size (Cohen's d) and percentage of improvement.

RESULTS

SAD clients with depression and GAD symptoms demonstrated statistically and clinically significant improvements in symptom severity, quality of life, work, social adjustment and model-related measures (i.e. negative emotionality/safety motivation, emotion regulation strategies). The improvements were largely maintained during the follow-up period and increased for some variables.

CONCLUSION

These findings showed preliminary evidence for the role of emotion dysregulation and motivational factors in the aetiology and maintenance of SAD and the efficacy of ERT in the treatment of co-morbid SAD.

From psychological to physical health: Exploring temporal precedence throughout emotion regulation therapy

OBJECTIVE

Generalized anxiety disorder (GAD) is characterized, in part, by physical symptoms such as muscle tension and gastrointestinal (GI) distress. To date, little research has examined how changes in psychological symptoms associated with GAD may impact physical symptoms. This study investigated if reductions in worry, anxiety, and depression precede changes in muscle tension and GI distress throughout psychotherapy.

METHODS

Participants with GAD (N = 85) completed 20 weeks of emotion regulation therapy (ERT) in addition to assessments pre, mid, and post treatment. They completed a physical symptom questionnaire, evaluating muscle tension and GI distress. Participants also completed psychological symptoms questionnaires, including the State Trait Anxiety Inventory (STAI-7), Penn State Worry Questionnaire (PSWQ), and Beck Depression Inventory (BDI-II). Control participants (N = 44) completed these measures at baseline.

RESULTS

Participants with GAD had significantly greater muscle tension (p <  .001) and GI distress (p <  .001) compared to control participants without GAD. Reductions in worry, depression, and trait anxiety did not precede changes in muscle tension (range of effect size (r): .05-.12). Reductions in both depression (p = 0.04) and trait anxiety (p < 0.01) preceded reductions in GI distress. Reductions in worry did not precede reductions in GI distress (p = 0.25).

CONCLUSION

These data provide preliminary evidence for the temporal effect of reductions in psychological symptoms on reductions in GI distress in GAD, highlighting the potential of psychotherapy to improve physical outcomes.

REMOTION Blended Transdiagnostic Intervention for Symptom Reduction and Improvement of Emotion Regulation in an Outpatient Psychotherapeutic Setting: Protocol for a Pilot Randomized Controlled Trial

BACKGROUND

Emotion regulation has been identified as an important transdiagnostic factor relevant to the treatment of mental health disorders. Many empirically validated psychotherapeutic treatments incorporate elements targeting emotion regulation. Most of these treatment approaches are conceptualized as standard face-to-face treatments not as blended treatments, which include an internet-based intervention.

OBJECTIVE

The aim of this study is to examine, for the first time, a new internet-based intervention-REMOTION-that will be provided transdiagnostically, as an add-on to psychotherapy, to provide a blended treatment format.

METHODS

A total of 70 participants will be assigned (1:1 allocation ratio) to either the intervention group (REMOTION + psychotherapy) or the treatment-as-usual group that receives psychotherapy alone. To maximize external validity, a typical outpatient treatment sample of patients diagnosed with a range of disorders such as depression, anxiety disorders, and adjustment disorder will be recruited from a university outpatient clinic. Patients with bipolar disorder, psychotic disorders, or acute suicidality will be excluded from the study. The feasibility and potential effectiveness of the intervention will be examined by assessing data at baseline, 6 weeks (post), and 12 weeks (follow-up). The primary outcome is general symptom severity, assessed with the Brief Symptom Inventory. Secondary outcomes are emotion regulation, depressive symptoms, anxiety symptoms, health related quality of life, well-being, and a variety of feasibility parameters. Quantitative data will be analyzed on an intention-to-treat basis.

RESULTS

Participant recruitment and data collection started in February 2020, and as of November 2020, are ongoing. Results for the study are expected in 2022.

CONCLUSIONS

This pilot randomized controlled trial will inform future studies using transdiagnostic blended treatment.

Neural correlates of mindful emotion regulation in high and low ruminators

Depressive rumination is considered a prominent risk factor for the occurrence, severity, and duration of depressive episodes. A variety of treatment options have been developed to treat depressive rumination of which mindfulness based programs are especially promising. In the current study, we investigated the neural underpinnings of a short mindfulness intervention and mindful emotion regulation in high and low trait ruminators in an ecologically valid environment using functional near-infrared spectroscopy (fNIRS). Participants were randomly assigned to a mindfulness instruction (MT) group or an instructed thinking (IT) group. Participants in the MT group were trained to either focus their attention mindfully on their breath or their emotions, while the IT group focused their attention on the past or future. Afterwards, all participants underwent an emotion regulation paradigm in which they either watched negative or neutral movie clips. During both paradigms cortical hemodynamic changes were assessed by means of fNIRS. Participants in the MT group showed lower activity in the cognitive control network (CCN) during the focus on breath condition in comparison to the focus on emotion condition. Additionally, oxygenated hemoglobin in the MT group tended to be lower than in the IT group. Further, self-reports of emotional distress during the instruction paradigm were reduced in the MT group. During the emotion regulation paradigm, we observed reduced emotional reactivity in terms of emotional distress and avoidance in the MT group in comparison to the IT group. Furthermore, on a neural level, we observed higher CCN activity in the MT group in comparison to the IT group. We did not find any effect of rumination, neither on the intervention nor on the emotion regulation task. The results of this pilot study are discussed in light of the present literature on the neural correlates of mindfulness based interventions in rumination and emphasize the use of fNIRS to track neural changes in situ over the course of therapy.

The association between Emotional Regulation and Internet Gaming Disorder

PURPOSE

Lack of control over Internet gaming habits may result in negative consequences. This study aimed to evaluate the emotional regulation of adults with Internet gaming disorder (IGD) and the association of emotion regulation, depression, and hostility.

METHODS

Advertisements were used to recruit 69 young adults with IGD, 69 sex- and age-matched controls, and 69 sex- and age-matched regular gamers. The diagnosis of IGD was according to diagnostic interviews based on DSM-5 IGD research criteria. Participants completed the Affective Style Questionnaire, the center of epidemiological studies depression scale and the short-form Chinese version of Buss-Durkee Hostility Inventory.

RESULTS

In the IGD group, the emotion adjustment score was significantly lower, whereas the scores for depression, and hostility were significantly higher than in the other two groups. In addition, emotion adjustment is the most associated emotion regulation behavior of IGD, followed by emotion concealment. In IGD group, emotion adjustment had a negative correlation with depression and hostility.

CONCLUSIONS

Our study demonstrate that emotion adjustment is significantly associated with IGD. The depression and hostility mediated the association. Knowing that emotion adjustment plays a critical role in IGD, future interventions should focus on this subscale of emotion regulation.

How to Relax in Stressful Situations: A Smart Stress Reduction System

Stress is an inescapable element of the modern age. Instances of untreated stress may lead to a reduction in the individual's health, well-being and socio-economic situation. Stress management application development for wearable smart devices is a growing market. The use of wearable smart devices and biofeedback for individualized real-life stress reduction interventions has received less attention. By using our unobtrusive automatic stress detection system for use with consumer-grade smart bands, we first detected stress levels. When a high stress level is detected, our system suggests the most appropriate relaxation method by analyzing the physical activity-based contextual information. In more restricted contexts, physical activity is lower and mobile relaxation methods might be more appropriate, whereas in free contexts traditional methods might be useful. We further compared traditional and mobile relaxation methods by using our stress level detection system during an eight day EU project training event involving 15 early stage researchers (mean age 28; gender 9 Male, 6 Female). Participants' daily stress levels were monitored and a range of traditional and mobile stress management techniques was applied. On day eight, participants were exposed to a 'stressful' event by being required to give an oral presentation. Insights about the success of both traditional and mobile relaxation methods by using the physiological signals and collected self-reports were provided.

A Randomized Controlled Trial of Emotion Regulation Therapy for Psychologically Distressed Caregivers of Cancer Patients

BACKGROUND

Previous cognitive behavioral therapies for informal caregivers (ICs) have produced negligible effects. The purpose of this study was to evaluate, in a randomized controlled trial, the efficacy of Emotion Regulation Therapy adapted for caregivers (ERT-C) on psychological and inflammatory outcomes in psychologically distressed ICs and the cancer patients cared for.

METHODS

A total of 81 ICs with elevated psychological distress were randomly assigned to ERT-C or a waitlist condition and assessed pre-, mid-, and post-treatment. In 52 cases, the patient cared for by the IC was included. Patients did not receive ERT-C. Both the ERT-C and waitlist groups were followed 3 and 6 months post-treatment. Data were analyzed with multilevel models, and P values were two-sided.

RESULTS

Compared with ICs in the waitlist condition, ICs in the ERT-C condition experienced medium to large statistically significant reductions in psychological distress (Hedge's g = 0.86, 95% confidence interval [CI] = 0.40 to 1.32, P < .001), worry (g = 0.96, 95% CI = 0.50 to 1.42, P < .001), and caregiver burden (g = 0.53, 95% CI = 0.10 to 1.99, P = .007) post-treatment. No statistically significant effects were found for rumination (g = 0.24, 95% CI = -0.20 to 0.68, P = .220). Results concerning caregiver burden were maintained through 6 months follow-up. Although the effects on psychological distress and worry diminished, their end-point effects remained medium to large. No statistically significant effects on systemic inflammation were detected (C-reactive protein: g = .17, 95% CI = -0.27 to 0.61, P = .570; interleukin-6: g = .35, 95% CI = -0.09 to 0.79, P = .205; tumor necrosis factor-alpha: g = .11, 95% CI = -0.33 to 0.55, P = .686). Patients whose ICs attended ERT-C experienced a large increase in quality of life post-treatment (g = 0.88, 95% CI = 0.18 to 1.58, P = .017).

CONCLUSIONS

To our knowledge, this is the first randomized controlled trial evaluating the efficacy of ERT-C for ICs. Given the previous disappointing effects of other cognitive behavioral therapies for this population, the present findings are very encouraging. Identifying ICs with elevated psychological distress and providing them with relevant psychotherapy appears an important element of comprehensive cancer care.

Emotion Regulation Therapy and Its Potential Role in the Treatment of Chronic Stress-Related Pathology Across Disorders

Although stress is an inevitable part of everyday life, its chronicity, severity, and perceived burden can result in enduring distress, which may manifest as heightened emotionality, contributing to a number of self-regulatory failures. Specifically, distress disorders are characterized, in part, by heightened sensitivity to underlying motivational systems related to threat/safety, reward/loss, or both. Further, individuals suffering from these conditions typically engage in perseverate negative thinking (e.g., worry, rumination, self-criticism) in an effort to manage motivationally relevant distress and often utilize these processes at the detriment of engaging in new contextual learning. Distress disorders are often brought on by enduring chronic stress, coupled with these maladaptive emotional, cognitive, and behavioral responses and ensuing impairment which contribute to and in turn worsen the deficits from these purported mechanisms. Emotion regulation therapy is a theoretically derived treatment that is based upon affective science to offer a blueprint for improving intervention by focusing on targeting the motivational responses and corresponding regulatory failures of individuals with distress disorders. Open and randomized controlled trials have demonstrated considerable preliminary evidence for the utility of emotion regulation therapy and its proposed mechanisms in treating the distress conditions.

Changes in Decentering and Reappraisal Temporally Precede Symptom Reduction During Emotion Regulation Therapy for Generalized Anxiety Disorder With and Without Co-Occurring Depression

Emotion Regulation Therapy (ERT) has demonstrated efficacy in both open and randomized trials for generalized anxiety disorder (GAD) with and without co-occurring depression. An important goal in ERT is to teach clients adaptive emotion regulation, including healthier metacognitive abilities such as decentering and cognitive reappraisal. A few studies thus far have demonstrated a mediating role for these metacognitive abilities in other cognitive behavioral therapies (CBTs) for GAD. However, a drawback to most of these has been the ability to demonstrate a causal role for improved metacognitive abilities in outcome. In the present study, we utilized multilevel time-lagged segment analyses to explore the temporal dynamics between session-by-session changes in metacognition and anxiety outcomes from ERT. Thirty-one young adults diagnosed with GAD with and without co-occurring depression received 16 sessions of ERT. Prior to each session, participants completed questionnaires pertaining to metacognition (i.e., decentering and cognitive reappraisal) and anxiety symptoms (i.e., worry, trait anxiousness, and generalized anxiety). Changes in decentering temporally preceded changes in worry and trait anxiousness of a medium to large magnitude, and changes in cognitive reappraisal temporally preceded changes in all three outcomes of a medium to large magnitude. The reverse direction, where mediators were predicted by outcomes, was nonsignificant. These findings support the notion that adaptive metacognitive emotion regulation is involved in reducing worry and anxiety in GAD. Having a clearer understanding of the temporal dynamics between metacognitive abilities and symptoms of anxiety can inform and improve not only ERT but other CBTs for GAD, as well.

When worry may be good for you: Worry severity and limbic-prefrontal functional connectivity in late-life generalized anxiety disorder

BACKGROUND

Late-life generalized anxiety disorder (GAD) is one of the most common anxiety disorders in older adults. However, its neural markers have received relatively little attention. In this study, we explored the association between worry severity and limbic-prefrontal connectivity during emotional reactivity in late-life GAD.

METHODS

We recruited 16 anxious (GAD) and 20 non-anxious (HC) older adults to perform the faces/shapes emotional reactivity task during functional magnetic resonance imaging (fMRI). We investigated the functional connectivity of both the amygdala and the bed nucleus of stria terminalis (BNST) with the prefrontal cortex (PFC) using generalized psychophysiological interaction (gPPI) analysis. We tested for (1) group differences in connectivity, (2) association between worry severity and connectivity, and (3) interaction between group and worry severity and its association with connectivity.

RESULTS

Amygdala-PFC and BNST-PFC functional connectivity were associated with worry severity in an inverse U-shape, and was independent of depression severity, global anxiety, neuroticism, and general cognitive function.

LIMITATIONS

Our limitations include slightly skewed PSWQ distributions, lack of non-anxious individuals with high worry, small sample size, and low depression comorbidity in a sample of late-life GAD that may not generalize to GAD in younger populations.

CONCLUSIONS

This suggests that moderate worry is associated with maximum engagement of the limbic-PFC connectivity, while severe worry is associated with failure of the limbic-PFC emotional regulation circuit. This may explain the aberrant and exaggerated responses to negative stimuli observed in participants with pathological worry.

All together now: utilizing common functional change principles to unify cognitive behavioral and mindfulness-based therapies

Cognitive behavior therapy (CBT) and mindfulness-based interventions (MBI) have made important contributions to resolving the global burden of mental illness. However, response rates are comparatively more modest for the distress disorders. Newer CBTs enriched with MBI components have emerged with promising findings for distress disorders but with a high degree of heterogeneity and, subsequently, an unclear path for determining the unique and synergistic contributions from CBTs and MBIs. We propose that one way to elucidate and improve upon this union is to identify common overarching principles (i.e. attention change; metacognitive change) that guide both approaches and to refine therapeutic processes to optimally reflect these common targets and their interplay (e.g. sequencing and dosing).

Emotion-Focused Cognitive-Behavioral Therapy for Youth with Anxiety Disorders: A Randomized Trial

Difficulties with emotion regulation are a core feature of anxiety disorders (ADs) in children and adults. Interventions with a specific focus on emotion regulation are gaining empirical support. Yet, no studies to date have compared the relative efficacy of such interventions to existing evidence-based treatments. Such comparisons are necessary to determine whether emotion-focused treatments might be more effective for youth exhibiting broad emotion-regulation difficulties at pretreatment. This study examined an emotion-focused cognitive-behavioral therapy (ECBT) protocol in comparison to traditional cognitive-behavioral therapy (CBT) in a sample of children with a primary anxiety disorder diagnosis. Moderation analyses examined whether children with higher levels of emotion dysregulation at pretreatment would show greater levels of improvement in ECBT than CBT. Ninety-two youth ages 7 to 12 years (58% male) with a primary diagnosis of separation anxiety disorder, generalized anxiety disorder, or social phobia were included. Participants were randomly assigned to ECBT or CBT. Results showed that youth in both conditions demonstrated similar improvements in emotion regulation and that pretreatment levels of emotion dysregulation did not moderate treatment outcomes. Additional analyses showed that ECBT and CBT were similarly effective on diagnostic, severity, and improvement measures. Future work is needed to further explore the ways that emotion regulation is related to treatment outcome for anxious youth.

The Translational Potential of Neuroimaging Genomic Analyses To Diagnosis And Treatment In The Mental Disorders

Imaging genomics focuses on characterizing genomic influence on the variation of neurobiological traits, holding promise for illuminating the pathogenesis, reforming the diagnostic system, and precision medicine of mental disorders. This paper aims to provide an overall picture of the current status of neuroimaging-genomic analyses in mental disorders, and how we can increase their translational potential into clinical practice. The review is organized around three perspectives. (a) Towards reliability, generalizability and interpretability, where we summarize the multivariate models and discuss the considerations and trade-offs of using these methods and how reliable findings may be reached, to serve as ground for further delineation. (b) Towards improved diagnosis, where we outline the advantages and challenges of constructing a dimensional transdiagnostic model and how imaging genomic analyses map into this framework to aid in deconstructing heterogeneity and achieving an optimal stratification of patients that better inform treatment planning. (c) Towards improved treatment. Here we highlight recent efforts and progress in elucidating the functional annotations that bridge between genomic risk and neurobiological abnormalities, in detecting genomic predisposition and prodromal neurodevelopmental changes, as well as in identifying imaging genomic biomarkers for predicting treatment response. Providing an overview of the challenges and promises, this review hopefully motivates imaging genomic studies with multivariate, dimensional and transdiagnostic designs for generalizable and interpretable findings that facilitate development of personalized treatment.

A neurobehavioral account for decentering as the salve for the distressed mind

Distress is commonly characterized by prolonged internal suffering that can range from self-focused processing of negative emotions and stressors, to highly intensely aversive and prolonged emotional states, thereby, worsening or complicating emotional and physical conditions. Decentering represents a metacognitive capacity thought to reflect three interrelated processes: meta-awareness, disidentification from internal experience, and reduced reactivity to thought content-which is reliably increased with mindfulness-based interventions. In this essay, we seek to link the clinical presentation of distress disorders to known or hypothesized disruptions in neural networks that underlie emotion, cognition, and goal directed behavior, and offer a neurobehavioral account for how and why treatments imbued with mindfulness meditation might ameliorate these conditions, in part through increases in decentering.

Changes in Functional Connectivity Following Treatment With Emotion Regulation Therapy

Emotion regulation therapy (ERT) is an efficacious treatment for distress disorders (i.e., depression and anxiety), predicated on a conceptual model wherein difficult to treat distress arises from intense emotionality (e.g., neuroticism, dispositional negativity) and is prolonged by negative self-referentiality (e.g., worry, rumination). Individuals with distress disorders exhibit disruptions in two corresponding brain networks including the salience network (SN) reflecting emotion/motivation and the default mode network (DMN) reflecting self-referentiality. Using resting-state functional connectivity (rsFC) analyses, seeded with primary regions in each of these networks, we investigated whether ERT was associated with theoretically consistent changes across nodes of these networks and whether these changes related to improvements in clinical outcomes. This study examined 21 generalized anxiety disorder (GAD) patients [with and without major depressive disorder (MDD)] drawn from a larger intervention trial (Renna et al., 2018a), who completed resting state fMRI scans before and after receiving 16 sessions of ERT. We utilized seed-based connectivity analysis with seeds in the posterior cingulate cortex (PCC), right anterior insula, and right posterior insula, to investigate whether ERT was associated with changes in connectivity of nodes of the DMN and SN networks to regions across the brain. Findings revealed statistically significant treatment linked changes in both the DMN and SN network nodes, and these changes were associated with clinical improvement corresponding to medium effect sizes. The results are discussed in light of a nuanced understanding of the role of connectivity changes in GAD and MDD, and begin to provide neural network support for the hypothesized treatment model predicated by ERT.

Look before you leap: the role of negative urgency in appraisals of ambiguous and unambiguous scenarios in individuals high in generalized anxiety disorder symptoms

Negative interpretation bias, the propensity to make threatening interpretations of ambiguous information, is associated with symptoms of generalized anxiety disorder (GAD). Apart from its relationship with intolerance of uncertainty (IU), little is known about what explains the presence of this cognitive bias in GAD. One factor may be negative urgency (NU), the tendency to take rash action when distressed, which is related to GAD symptoms and to cognitive biases in nonclinical populations. The aim of the present study was to examine the relationship between NU and interpretation bias in individuals high in GAD symptoms (N = 111). IU, trait anxiety, and other forms of impulsivity were examined concurrently as competing correlates of interpretation bias. Greater NU and IU were found to be unique correlates of greater threatening interpretations of ambiguous scenarios. Greater NU was also a unique correlate of greater threatening interpretations of negative and positive scenarios. No other forms of impulsivity were uniquely related to interpretation bias. The findings suggest that greater NU may have a role in the tendency for individuals high in GAD symptoms to make threatening interpretations in response to ambiguous scenarios, overtly threatening situations, and situations without indication of threat or danger. Theoretical implications of these findings are discussed.

Itch and psyche: psychiatric aspects of pruritus

Itch, also referred to as pruritus, is an unpleasant cutaneous sensation provoking the desire to scratch. It is often an uncomfortable, subjective sensation responsible for decreased quality of life in a variety of psychodermatological conditions. Comorbid psychiatric conditions, including depression and anxiety, are frequently associated with itch and scratch cycle. The reciprocal and intricate relationship between the psyche and itch has been widely studied. The neurobiology of itch involves the complexity of specific mediators, itch-related neuronal pathways, and central processing of itch. The connection between itch and the psyche can be grouped under three headings: pruritic diseases with psychosocial sequelae, pruritic diseases aggravated by psychosocial factors, and psychiatric disorders causing pruritus. Itch and pain modulation go together in most circumstances and involve various substances including histamine, interleukins, protease-activated receptors, transient receptor potential receptors, opioids, and cannabinoids. The close interaction between keratinocytes and nerve endings modulating pain and itch also play a major role. Management of itch associated with its psychosomatic components is directed at an underlying cause and adopting a holistic approach to address not only dermatologic and somatosensory aspects, but also the cognitive, emotional, and psychosocial components. An integrated multidisciplinary team consisting of a dermatologist, psychiatrist, psychologist, and social worker is vital in addressing the multifaceted aspects of pruritus.

Emotion regulation in autism: Reappraisal and suppression interactions

Emotion regulation has been proposed to be a transdiagnostic factor in the development and maintenance of psychopathology in the general population, yet the nature of the relationships between emotion regulation strategy use and psychological well-being has not been comprehensively explored in individuals with autism spectrum disorder (ASD). The aim of this study was to assess how the individual differences in self-reported emotion regulation strategy use relate to levels of both positive and negative psychological well-being. In total, 56 individuals with ASD aged 14-24 years (M_age = 18.15; SD_age = 2.30) completed Emotion Regulation Questionnaire, Diagnostic and Statistical Manual of Mental Disorders-5 Generalized Anxiety Disorder Dimensional Scale, Patient Health Questionnaire-9, Warwick-Edinburgh Mental Well-being Scale and Autism-Spectrum Quotient - Short. Individuals were grouped into four clusters based on their Emotion Regulation Questionnaire subscale scores. Individuals in the high suppression and low reappraisal group expressed higher depressive symptoms and lower positive well-being when compared with the low suppression and high reappraisal group. Interestingly, individuals who self-reported using both high suppression and reappraisal expressed relatively high positive well-being and low depression symptoms. We suggest that the maladaptive effect of habitual suppression usage may be buffered by the habitual use of reappraisal, and this interaction between adaptive and maladaptive emotion regulation strategy use has clinical implications.

A Pilot Study of Emotion Regulation Therapy for Generalized Anxiety and Depression: Findings From a Diverse Sample of Young Adults

Emotion regulation therapy (ERT) for generalized anxiety disorder (GAD) and accompanying major depressive disorder (MDD) is a theoretically derived, evidence-based treatment that integrates principles from traditional and contemporary cognitive-behavioral and experiential approaches with basic and translational findings from affect science to offer a blueprint for improving intervention by focusing on the motivational responses and corresponding self-referential regulatory characteristics. Preliminary evidence supports the efficacy of a 20-session version of ERT. However, previous trials of ERT and other traditional and contemporary cognitive-behavioral therapies have often utilized relatively homogeneous samples. Various contextual and demographic factors may be associated with challenges that increase risk for negative mental and social outcomes for young adults ages 18-29, particularly for individuals from diverse backgrounds. The aim of this pilot study was to examine the effectiveness of a briefer 16-session version of ERT in a racially and ethnically diverse sample of young adults. Participants (N = 31) were enrolled at an urban-based, commuter college who consented to treatment for anxiety, worry, or depression at an on-campus counseling center. Open-trial results demonstrate strong ameliorative changes in worry, rumination, self-reported and clinician-rated GAD and MDD severity, social disability, quality of life, attentional flexibility, decentering/distancing, reappraisal, trait mindfulness, and negative emotionality from pre- to posttreatment. These gains were maintained throughout a 3- and 9-month follow-up. These findings provide preliminary evidence for the efficacy of ERT in treating a racially and ethnically heterogeneous population. Further, this study highlights comparable effectiveness of a briefer 16-session version of ERT.

Are attitudes towards emotions associated with depression? A Conceptual and meta-analytic review

OBJECTIVES

We performed a conceptual and meta-analytic review of the relationship between negative cognitive and affective evaluations of negative emotional experiences (negative ATE) and depression. We examined the negative ATE-depression relationship in terms of three ATE constructs: fear of emotion, non-acceptance of emotion, and distress intolerance. We also explored whether the negative ATE-depression relationship differs as a function of specific emotions.

METHODS

Seventy articles with a total sample of 19950 adults were included in the general analysis, and 10 studies with a total sample of 1726 were included in the emotion-specific analysis.

RESULTS

In the general analysis, negative ATE was associated with depression with a medium to large effect. Notably, this effect size was stronger than previously observed associations between emotion regulation strategies and depression (Aldao et al., 2010). In the emotion-specific analysis, negative attitudes towards depressive affect had a particularly strong association with depression.

LIMITATIONS

Limitations include heterogeneity in effect sizes and a small number of samples for the emotion-specific analyses.

CONCLUSIONS

The present review is the first to establish a systematic relationship between negative ATE and depression. We close with suggestions for future work designed to understand why negative ATE is related to depression, which can lead to understanding of depression's etiology and ways to refine interventions to alter ATE.
