The moderating effects of anger suppression and anger expression on cognitive behavioral group therapy and mindfulness-based stress reduction among individuals with social anxiety disorder

Prescriptive Predictors of Mindfulness Ecological Momentary Intervention for Social Anxiety Disorder: Machine Learning Analysis of Randomized Controlled Trial Data

BACKGROUND

Shame and stigma often prevent individuals with social anxiety disorder (SAD) from seeking and attending costly and time-intensive psychotherapies, highlighting the importance of brief, low-cost, and scalable treatments. Creating prescriptive outcome prediction models is thus crucial for identifying which clients with SAD might gain the most from a unique scalable treatment option. Nevertheless, widely used classical regression methods might not optimally capture complex nonlinear associations and interactions.

OBJECTIVE

Precision medicine approaches were thus harnessed to examine prescriptive predictors of optimization to a 14-day fully self-guided mindfulness ecological momentary intervention (MEMI) over a self-monitoring app (SM).

METHODS

This study involved 191 participants who had probable SAD. Participants were randomly assigned to MEMI (n=96) or SM (n=95). They completed self-reports of symptoms, risk factors, treatment, and sociodemographics at baseline, posttreatment, and 1-month follow-up (1MFU). Machine learning (ML) models with 17 predictors of optimization to MEMI over SM, defined as a higher probability of SAD remission from MEMI at posttreatment and 1MFU, were evaluated. The Social Phobia Diagnostic Questionnaire, structurally equivalent to the Diagnostic and Statistical Manual SAD criteria, was used to define remission. These ML models included random forest and support vector machines (radial basis function kernel) and 10-fold nested cross-validation that separated model training, minimal tuning in inner folds, and model testing in outer folds.

RESULTS

ML models outperformed logistic regression. The multivariable ML models using the 10 most important predictors achieved good performance, with the area under the receiver operating characteristic curve (AU-ROC) values ranging from .71 to .72 at posttreatment and 1MFU. These prerandomization and early-stage prescriptive predictors consistently identified which participants had the highest probability of optimization of MEMI over SM after 14 days and 6 weeks from baseline. Significant predictors included 4 strengths (higher trait mindfulness, lower SAD severity, presence of university education, no current psychotropic medication use), 2 weaknesses (higher generalized anxiety severity and clinician-diagnosed depression or anxiety disorder), and 1 sociodemographic variable (Chinese ethnicity). Emotion dysregulation and current psychotherapy predicted remission with inconsistent signs across time points.

CONCLUSIONS

The AU-ROC values indicated moderately meaningful effect sizes in identifying prescriptive predictors within multivariable models for clients with SAD. Focusing on the identified notable client strengths, weaknesses, and Chinese ethnicity may enhance our ability to predict future responses to scalable treatments. Estimating the likelihood of SAD remission with a "prescriptive predictor calculator" for each client may help clinicians and policymakers allocate scarce treatment resources effectively. Clients with high remission probability may benefit from receiving the MEMI as a vigilant waitlist strategy before intensive therapist-led psychotherapy. These efforts may aid in creating actionable treatment selection tools to optimize care for clients with SAD in routine health care settings that use stratified care principles.

Effects of Mindfulness-Based Stress Reduction Therapy on Posttraumatic Growth and Quality of Life in Patients With Breast Cancer Under Early Chemotherapy: A Randomized Controlled Trial

Posttraumatic growth (PTG) in patients with breast cancer has been reported. Mindfulness-based stress reduction (MBSR) has been found to be effective in improving the psychological well-being during cancer care. This study aimed to evaluate the impact of MBSR on the levels of PTG, perceived social support, and quality of life. A sample of 101 participants who experienced early chemotherapy enrolled in an MBSR group (n = 50) and a routine care group (n = 51) for 8 weeks. Their postintervention data were combined with preintervention data through a bundle of questionnaires reporting levels of PTG, perceived social support, and quality of life. MBSR showed the prominent validity in raising the levels of PTG and increasing in perceived social support and quality of life from pre- to posttreatment. MBSR improved the levels of PTG, perceived social support, and quality of life in patients with breast cancer in early chemotherapy. In conclusion, MBSR may help to optimize the positive psychological processes that will be targeted to maximize the efficacy of treatment for future cancer survivors.

The Role of Dietary Antioxidants, Food Supplements and Functional Foods for Energy Enhancement in Healthcare Professionals

Healthcare professionals frequently experience significant work overload, which often leads to substantial physical and psychological stress. This stress is closely linked to increased oxidative stress and a corresponding decline in energy levels. This scoping review investigates the potential impact of dietary antioxidants and food supplements in conjunction with diet in controlling these negative effects. Through an analysis of the biochemical pathways involved in oxidative stress and energy metabolism, the paper emphasizes the effectiveness of targeted dietary interventions. Key dietary antioxidants, such as vitamins C and E, polyphenols, and carotenoids, are evaluated for their ability to counteract oxidative stress and enhance energy levels. Additionally, the review assesses various food supplements, including omega-3 fatty acids, coenzyme Q10, and ginseng, and their mechanisms of action in energy enhancement. Practical guidelines for incorporating energy-boost dietary strategies into the routine of healthcare professionals are provided, emphasizing the importance of dietary modifications in reducing oxidative stress and improving overall well-being and performance in high-stress healthcare environments. The review concludes by suggesting directions for future research to validate these findings and to explore new dietary interventions that may further support healthcare professionals under work overload.

Cognitive behavioral group therapy for social anxiety disorder - A critical review of methodological designs

Social anxiety disorder (SAD) is highly prevalent with significant lifetime impacts, especially when left untreated. Cognitive behavioral therapy is the current gold standard treatment with successful patient outcomes. Cognitive behavioral group therapy (CBGT) is one form that provides unique benefits to participants including normalization of symptoms and social support, as well as providing increased access to treatment at a lower per-session cost. Research on this mode of treatment has been ongoing for over 20 years, but we still have much to learn about its overall efficacy. The goals of this critical review were to summarize and evaluate the most current research, including an analysis of the overall methodological design quality, and provide recommendations for the enhancement of future studies based on best practices. Recent studies included some best practice design elements used in measuring efficacy such as the use of comparison groups, masking procedures, fidelity assessments, and consideration of clinical significance in outcomes. However, many gaps exist such as a lack of consensus around measures and therapy manuals, as well as baseline competencies of facilitators. Future studies should consider incorporating additional best practice elements aligning with study goals to strengthen designs and provide the field with even more confidence in this mode of treatment.

Paranoia and Social Anxiety: Predicting Aggressive Behavior

Aggression is a transdiagnostic behavior that is associated with poor clinical outcomes. As such, it is important to understand factors that contribute to various manifestations of aggressive behavior. Recent research has revealed a subtype of individuals with social anxiety disorder (SAD) who tend to display relatively high amounts of aggression and experience more severe social anxiety and dysfunction compared to individuals in the prototypical SAD group. The current study used a status threat manipulation along with behavioral indices of aggression to examine the impact of paranoia and social anxiety symptom severity on aggression in a sample of undergraduates with social anxiety (N = 220). Analyses indicated that paranoia uniquely predicted indirect aggression whereas an interaction between social status threat, paranoia, and social anxiety severity uniquely predicted direct aggression. These findings suggest that paranoia may be a particularly important contributor to aggression among individuals with social anxiety.

Can Yogic Breathing Techniques Like Simha Kriya and Isha Kriya Regulate COVID-19-Related Stress?

The global impact of Coronavirus Disease 2019 (COVID-19) is tremendous on human life, not only affecting the physical and mental health of population but also impacting the economic system of countries and individual itself. The present situation demands prompt response toward COVID-19 by equipping the humans with strategies to overcome the infection and stress associated with it. These strategies must not only be limited to preventive and therapeutic measures, but also aim at improving immunity and mental health. This can be achieved by yogic breathing techniques. In this perspective, we emphasize the importance of yogic breathing, Simha Kriya and Isha kriya, the simple yet effective breathing techniques.
