The Importance of Psychological Assessment in the Management of Bladder Pain Syndrome/Interstitial Cystitis and Vulvodynia: A Case Report.

This case report emphasizes the crucial role of psychological assessment in the management of patients with bladder pain syndrome/interstitial cystitis (BPS/IC) and vulvodynia. A 48-year-old woman with a five-year history of refractory BPS/IC and vulvodynia presented with frequent urination, pelvic pain, and severe dyspareunia, which led to sexual aversion and divorce from her partner. Previous treatments, including lifestyle modifications, analgesics, anticholinergics, hydrodistension, intravesical dimethyl sulfoxide, and psychiatric interventions, had been ineffective. Psychological assessments using the Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, and Toronto Alexithymia Scale-20 revealed severe symptoms of depression, anxiety, and alexithymia. Due to the patient's sexual aversion and the absence of a partner, a complete Female Sexual Function Index (FSFI) could not be administered. Instead, a partial FSFI and artificial intelligence-translated reference value of the Female Sexual Distress Scale-Revised were used to assess aspects relevant to the patient's condition. The patient underwent three monthly sessions of Fotona laser therapy, erbium, and neodymium laser at one-month intervals. Treatment outcomes were evaluated using the Numeric Rating Scale-11, Vulvodynia Total, Interstitial Cystitis Symptom Index, and psychological assessment tools. At the six-month follow-up, all physical and psychological symptoms showed significant improvement and complete remission was achieved at 12 months. Despite the overall positive treatment outcomes, the patient's sexual aversion persisted, and accurate measurement was not possible, highlighting the complexity of addressing sexual function in patients with BPS/IC and vulvodynia. This case report underscores the need for a holistic approach to managing these conditions, addressing both the physical and psychological aspects of the disease.

Assessing the prevalence of generalized anxiety disorder in a multicultural medical education setting in Saudi Arabia during the COVID-19 pandemic.

Introduction: Mental health among medical students is an area that has been increasingly garnering world-wide attention. Yet, despite this increased attention, research related to anxiety disorders in Saudi Arabia remain limited. This study aims to address this gap by assessing the prevalence of generalized anxiety disorder (GAD) as well as explore its association with students' sociodemographic factors and academic performance among medical students in a Saudi Arabian institute that has a diverse, multicultural student body. Methods: The study takes place in a unique educational environment: a privately funded institute in Riyadh, the capital of Saudi Arabia, with 32% of its student body comprising international students from over 40 countries, during the COVID-19 pandemic. The study deploys the use of a survey that was sent to the students at this institute via their institutional emails. A survey containing 33 items assessing demographics, GAD using GAD-7 questionnaire, stress-relief measures, online learning experience during the pandemic, mental disorders, anxiety associated with the pandemic, two open-ended questions, and one item assessing sleep difficulty. Results: The results of the survey showed that a significant majority of the responders' scores in the GAD-7 assessment were in the range of moderate to severe anxiety. The results also suggest that low cGPA and the first academic years are significantly associated with higher GAD-7 scores. Students found severe time constraints, difficult educational content, and lack of psychological support to be major sources of stress. Furthermore, students suggested providing an in-house psychologist, personalized feedback, and guidance on study tactics as methods to reduce anxiety. Conclusion: These findings, among others, suggest a need for further studies and research in this field to uncover broader patterns and inform targeted mental health support strategies.

The Emergence of Mania After Initiating Escitalopram for Anxiety Disorder.

The abrupt transition into mania, known as a bipolar switch, poses a significant challenge in the treatment of mental illnesses. We present a case of a 22-year-old Hispanic female with generalized anxiety disorder (GAD) and autism spectrum disorder (ASD) who developed mania within five days after initiating escitalopram 5 mg. The patient had no reported history of bipolar disorder prior to this episode, and an extensive medical workup ruled out organic causes. The patient was in the acute inpatient psychiatric unit for 25 days and returned to baseline after discontinuation of escitalopram and initiating divalproex and olanzapine. This case underscores the potential risk of a bipolar switch with antidepressant use and highlights the importance of vigilant monitoring and considering underlying bipolarity in such patients.

Exercise and Anxiety.

Anxiety disorders are among the most commonly diagnosed mental health disorders in the United States - affecting over 40 million adults per year. Although anxiety disorders are commonly treated via psychotherapy and/or pharmacotherapy, there is also accumulating evidence to suggest that physical activity and exercise may play an important role in prevention and treatment. This chapter provides an extensive overview of literature examining the effects of physical activity, acute bouts of exercise, and chronic exercise training on several anxiety outcomes, primarily in adults. The collective evidence to date suggests that: (1) an acute bout of aerobic or resistance exercise generally results in reductions in state anxiety among adults with and without clinical anxiety disorders, (2) greater levels of physical activity are associated with fewer anxiety symptoms and a reduced likelihood of developing an anxiety disorder, (3) exercise training (aerobic and resistance) appears to reduce general anxiety symptoms in adults without a clinical anxiety disorder and adults with a chronic illness (e.g., cardiovascular disease) and may reduce disorder-specific symptoms of anxiety in adults with a clinical anxiety disorder. Although the collective body of evidence is promising, there is a need for additional well-designed and adequately powered randomized controlled trials, especially among adults with clinical anxiety disorders.

Algorithm-Based Modular Psychotherapy Alleviates Brain Inflammation in Generalized Anxiety Disorder.

Generalized anxiety disorder (GAD) is marked by prolonged and excessive worry, physical signs of anxiety, and associated neuroinflammation. Traditional treatments, like pharmacotherapy and cognitive-behavioral therapy (CBT), often leave residual symptoms and have high relapse rates. This study aimed to explore the efficacy of algorithm-based modular psychotherapy (MoBa), a combination of CBT and mindfulness meditation as validated by the research domain criteria (RDoC), in reducing anxiety and neuroinflammation in GAD. A longitudinal design was used, with 50 patients with GAD undergoing a 12-week MoBa treatment. The patients were investigated pre- and post-treatment using MRI to measure neuroinflammatory markers (DBSI-RF, diffusion-basis spectral imaging-based restricted fraction) in the hippocampus, amygdala, and neocortex. Clinical symptoms were assessed using the Hamilton Anxiety Rating Scale (HAM-A) and the Generalized Anxiety Disorder 7-item scale (GAD-7). Results indicated significant reductions in both anxiety symptoms and MRI RF values in the amygdala, suggesting decreased neuroinflammation. A reduction in anxiety was associated with the amelioration of neuroinflammation in the amygdala. These results suggest that MoBa is effective in alleviating both the psychological and neuroinflammatory aspects of GAD, offering a promising personalized treatment approach. Future research should focus on long-term effects and the mechanisms through which MoBa impacts neuroinflammation and anxiety.

Comparing the Efficacy of Electronically Delivered Cognitive Behavioral Therapy (e-CBT) to Weekly Online Mental Health Check-Ins for Generalized Anxiety Disorder-A Randomized Controlled Trial: Comparaison de l'efficacité de la thérapie cognitivo-comportementale délivrée par voie électronique (e-TCC) aux contrôles hebdomadaires en ligne de santé mentale pour le trouble d'anxiété généralisée - un essai randomisé contrôlé.

BACKGROUND: Generalized anxiety disorder (GAD) is a prevalent anxiety disorder characterized by uncontrollable worry, trouble sleeping, muscle tension, and irritability. Cognitive behavioural therapy (CBT) is one of the first-line treatments that has demonstrated high efficacy in reducing symptoms of anxiety. Electronically delivered CBT (e-CBT) has been a promising adaptation of in-person treatment, showing comparable efficacy with increased accessibility and scalability. Finding further scalable interventions that can offer benefits to patients requiring less intensive interventions can allow for better resource allocation. Some studies have indicated that weekly check-ins can also lead to improvements in GAD symptoms. However, there is a lack of research exploring the potential benefits of online check-ins for patients with GAD. OBJECTIVE: This study aims to investigate the effects of weekly online asynchronous check-ins on patients diagnosed with GAD and compare it with a group receiving e-CBT. METHODS: Participants (n e-CBT = 45; n check-in = 51) with GAD were randomized into either an e-CBT or a mental health check-in program for 12 weeks. Participants in the e-CBT program completed pre-designed modules and homework assignments through a secure online delivery platform where they received personalized feedback from a trained care provider. Participants in the mental health check-in condition had weekly asynchronous messaging communication with a care provider where they were asked structured questions with a different weekly theme to encourage conversation. RESULTS: Both treatments demonstrated statistically significant reductions in GAD-7-item questionnaire (GAD-7) scores over time, but when comparing the groups there was no significant difference between the treatments. The number of participants who dropped out and baseline scores on all questionnaires were comparable for both groups. CONCLUSIONS: The findings support the effectiveness of e-CBT and mental health check-ins for the treatment of GAD.

Comparing the Effectiveness of Electronically Delivered Therapy (e-CBT) to Weekly Online Mental Health Check-ins for Generalized Anxiety Disorder­A Randomized Controlled TrialPlain Language SummaryGeneralized anxiety disorder (GAD) is a prevalent psychiatric condition that leads to symptoms like uncontrollable worry, trouble sleeping, muscle tension, and irritability. Cognitive behavioural therapy (CBT) is a common psychotherapy used for GAD since it has been shown to reduce symptoms. However, traditional CBT that is in person can have barriers such as being inaccessible and costly, and therefore electronically delivered CBT (e-CBT) is a viable alternative since previous studies have shown its efficacy in reducing symptoms and being similar compared to face-to-face CBT. Previous studies have also shown reductions in GAD symptomology through the use of checking in on people and their mental health. Therefore, this study aimed to compare e-CBT to a check-in condition and had a total of 45 individuals in e-CBT and 51 participants in the check-in condition. Participants in the e-CBT condition completed 12 weeks of predesigned e-CBT modules, homework and received personalized feedback from a care provider. In contrast, individuals in the check-in condition completed 12 weeks of unstructured asynchronous messaging with a care provider. Results from the study showed that both the e-CBT and check-in condition demonstrated statistically significant improvements in GAD-7 across time, but when comparing the groups there was no significant difference. The results show the efficacy of e-CBT and checking in on people's mental health to reduce GAD and future research should examine the 2 conditions combined.

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.

Correlates of treatment-seeking in DSM-5 generalized anxiety disorder: Findings from the National Epidemiologic Survey on Alcohol and Related Conditions-III.

Generalized Anxiety Disorder (GAD) presents a significant personal and societal burden and is associated with chronic medical comorbidities and markedly lower quality of life. Effective treatments exist, less than half of individuals with lifetime GAD will ever seek psychotherapeutic or pharmacological treatment. A thorough understanding of the factors that influence treatment seeking for GAD is warranted. The present study investigates the correlates of GAD treatment seeking, using data from the National Epidemiological Survey on Alcohol and Related Disorders-III (NESARC-III), which assessed for psychiatric disorders using the Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-5 Version (AUDADIS-5). A series of logistic regressions were run to identify demographic, diagnostic, and symptom-level correlates of treatment seeking in those meeting DSM-5 diagnostic criteria for GAD. Comorbid depression, panic disorder, and PTSD were all uniquely associated with higher rates of GAD-related treatment seeking. Additionally, several accompanying anxiety symptoms were also uniquely predicted treatment seeking, including fatigue, panic attacks, reassurance-seeking, and interpersonal avoidance. Findings underscore the multi-factorial nature of treatment seeking behavior in GAD and highlight the need for further research to fully understand these relationships and devise effective strategies to improve treatment seeking in this population.

A clinical study based on bidirectional Mendelian randomization: Correlation between generalized anxiety disorder and weight-bearing joints osteoarthritis.

Objectives: Bidirectional Mendelian randomization (MR) combined with clinical case analysis was used to elucidate the relationship between generalized anxiety disorder (GAD) caused by mental overload and the risk of weight-bearing joint (hip/knee) osteoarthritis (OA). Methods: We performed MR analyses using publicly released genome-wide association study summary statistics to measure the causal effects between mental overload and weight-bearing joint OA risk. The primary MR analysis utilized the inverse-variance weighted (IVW) method, complemented by additional methods, including simple mode, weighted mode, MR-Egger regression, and weighted median. The leave-one-out method was used for sensitivity analysis. Concurrently, data from patients with OA (Kellgren-Lawrence grades III-IV) who needed total knee/hip arthroplasty were collected. Patient assessments were conducted utilizing the Western Ontario and McMaster Universities arthritis index, Penn State worry questionnaire, and visual analogue scale. Results: Genetically predisposed GAD did not correlate with the risk of weight-bearing joint OA (IVW odds ratio [OR] = 0.840, 95 % confidence interval = 0.128, 5.50, P = 0.855). In reverse MR analyses, we detected no causal effect of weight-bearing OA on GAD (IVW OR = 1.00, 95 % CI = 0.985, 1.03, P = 0.687). In the clinical case evaluation, weight overload joint OA and GAD were highly correlated. Conclusion: MR analysis indicated no bidirectional causal effect of GAD caused by mental overload on weight-bearing joint (hip or knee) OA. Clinical studies support the finding that GAD is highly correlated with weight-bearing joint OA. However, whether there is a causal relationship between GAD caused by mental overload and weight-overloading joint OA requires further investigation.

Originalbeiträge (Originals). Network meta-analysis: science or alchemy? ­What works best in generalized anxiety disorder?

Recently Papola et al. (2023) published a network meta-analysis (NMA) on psychotherapy of generalized anxiety disorder (GAD) and concluded that cognitive-behavioral therapy (CBT) should be considered the first-line treatment for GAD. However, there are several concerns with regard to the procedures and the conclusions of this NMA and of NMA in general. We show that these concerns question the conclusions by Papola et al. Furthermore, we place concerns about thisNMAin a broader context and question whether existing evidence is consistent with the notion that one form of psychotherapy can be regarded as the gold standard for mental disorders and for all patients and therapists.

Association between living alone and generalized anxiety disorder in Korean adults.

BACKGROUND: Globally, the rise in single-person households poses a potential risk to mental health, with generalized anxiety disorder (GAD) being a prominent concern. The proliferation of single-person households may exacerbate social isolation and foster loneliness and anxiety. Notably, research investigating the association between single-person households and GAD remains limited. Therefore, this study aimed to investigate the association between single-person households and GAD across sexes in Korea. METHODS: We utilized data from the Korea National Health and Nutrition Examination Survey conducted in 2021 and 2022, comprising a sample of 9936 participants aged 19 or older. The Generalized Anxiety Disorder Screening Tool (GAD-7) was employed to assess anxiety levels in adults. Multiple logistic regression analysis was conducted to investigate the correlation between single-person households and GAD. RESULTS: The reference variable used in the analysis was multi-person households (consisting of two or more individuals). The association between single-person households and GAD was statistically significant across sexes (male: odds ratio [OR]: 1.92, 95 % CI: 1.15-3.20; female: OR: 1.56, 95 % CI: 1.03-2.36). Participants in single-person households exhibited higher scores on the GAD-7 compared with those in multi-person households. Notably, marital status and education level displayed disparate effects based on sex, whereas physical activity demonstrated consistent effects irrespective of sex. LIMITATIONS: Given the use of cross-sectional data, only correlations could be established. CONCLUSION: The findings indicate an elevated risk of GAD in single-person households compared with multi-person households. Furthermore, promoting physical activity emerged as a potential strategy for mitigating GAD in single-person households.

A Note on Ising Network Analysis with Missing Data.

The Ising model has become a popular psychometric model for analyzing item response data. The statistical inference of the Ising model is typically carried out via a pseudo-likelihood, as the standard likelihood approach suffers from a high computational cost when there are many variables (i.e., items). Unfortunately, the presence of missing values can hinder the use of pseudo-likelihood, and a listwise deletion approach for missing data treatment may introduce a substantial bias into the estimation and sometimes yield misleading interpretations. This paper proposes a conditional Bayesian framework for Ising network analysis with missing data, which integrates a pseudo-likelihood approach with iterative data imputation. An asymptotic theory is established for the method. Furthermore, a computationally efficient Pólya-Gamma data augmentation procedure is proposed to streamline the sampling of model parameters. The method's performance is shown through simulations and a real-world application to data on major depressive and generalized anxiety disorders from the National Epidemiological Survey on Alcohol and Related Conditions (NESARC).

Altered serum interleukin-17A and interleukin-23A levels may be associated with the pathophysiology and development of generalized anxiety disorder.

In recent times, the pathogenesis of generalized anxiety disorder (GAD) and the influence of pro- and anti-inflammatory cytokines on it have garnered considerable interest. Cytokine research, especially Th-17 cytokine research on GAD patients, is limited. Here, we aim to assess the role of interleukin-17A (IL-17A) and interleukin-23A (IL-23A) in the pathophysiology and development of GAD. This investigation included 50 GAD patients and 38 age-sex-matched healthy controls (HCs). A psychiatrist diagnosed patients with GAD and assessed symptom severity using the DSM-5 and the GAD-7 scales. The serum concentrations of IL-17A and IL-23A were determined using commercially available ELISA kits. GAD patients exhibited elevated levels of IL-17A (77.14 ± 58.30 pg/ml) and IL-23A (644.90 ± 296.70 pg/ml) compared to HCs (43.50 ± 25.54 pg/ml and 334.40 ± 176.0 pg/ml). We observed a positive correlation between disease severity and cytokine changes (IL-23A: r = 0.359, p = 0.039; IL-17A: r = 0.397, p = 0.032). These findings indicate that IL-17A and IL-23A may be associated with the pathophysiology of GAD. ROC analysis revealed moderately higher AUC values (IL-23A: 0.824 and IL-17A: 0.710), demonstrating their potential to discriminate between patients and HCs. Also, the sensitivity values of both cytokines were relatively higher (IL-23A: 80.49% and IL-17A: 77.27%). According to the present findings, there may be an association between peripheral serum levels of IL-17A and IL-23A and the pathophysiology and development of GAD. These altered serum IL-17A and IL-23A levels may play a role in directing the early risk of developing GAD. We recommend further research to ascertain their exact role in the pathophysiology and their performance as risk assessment markers of GAD.

Association between watching eating broadcasts like mukbang and cookbang and generalized anxiety disorder among Korean adolescents.

BACKGROUND: Anxiety disorders are common during adolescence; therefore, detecting anxiety disorders among adolescents and providing appropriate treatment are crucial. Studies have suggested that watching online audiovisual broadcasts like mukbang and cookbang (hereafter mukbang), where hosts eat or cook food, may influence anxiety disorders. However, there is insufficient research on the association between watching mukbang and generalized anxiety disorder (GAD). Therefore, we investigated the association between watching mukbang and GAD among Korean adolescents. METHODS: We analyzed 51,764 adolescents who participated in the 2020 Korea Youth Risk Behavior Web-Based Survey (KYRBS). The participants were asked how frequently they watched mukbang per week over the past 12 months. Anxiety disorders were assessed using the generalized anxiety disorder-7 (GAD-7) questionnaire. A multiple logistic regression analysis was performed after adjusting for confounding variables. RESULTS: The prevalence of GAD was higher among adolescents who watched mukbang compared to those who did not (aOR: 1.100, 95% CI: 1.026-1.180, P = 0.008 in male participants; aOR: 1.090, 95% CI: 1.003-1.185, P = 0.042 in female participants). The frequency of watching mukbang showed a dose-dependent relationship with a greater likelihood of GAD in female adolescents. CONCLUSION: This study's results showed that watching mukbang is associated with GAD in Korean adolescents. Proper interventions for mental health are needed for adolescents who watch mukbang.

[Mechanism of Dabugan Decoction in treatment of generalized anxiety disorder based on network pharmacology and experimental verification].

This study aims to explore the mechanism of Dabugan Decoction in the treatment of generalized anxiety disorder(GAD) based on network pharmacology, molecular docking, and animal experiments. Network pharmacology and molecular docking technology were used to obtain the possible targets and related signaling pathways of Dabugan Decoction in the treatment of GAD. The GAD rat model was established, and the corresponding drugs were given by gavage after randomization. After 28 days of continuous intervention, the anxiety state of rats was detected, and the pathological changes of the hippocampus were detected in each group. ELISA and Western blot were used to detect the protein expression levels of related molecules. A total of 65 drug compounds in Dabugan Decoction were obtained, involving 403 targets of action, 7 398 disease targets of GAD, and 279 common targets of "drug-disease". The key nodes in the protein-protein interaction(PPI) network were Akt1, TNF, IL-6, TP53, IL-1ß, etc. Function analysis of Gene Ontology(GO) and enrichment analysis of Kyoto Encyclopedia of Genes and Genomes(KEGG) showed that the PI3K-Akt signaling pathway was the most important pathway. The results of molecular docking showed that the core components of the drug had good binding activity with the corresponding key targets. Animal experiments showed that Dabugan Decoction could effectively improve the anxiety behavior of rats and increase the open arm end movement distance and total distance of rats in the elevated cross labyrinth, the number and stay time of entering the open box, and the time(%) and the number of entering the center of the open field. At the same time, HE staining and Nicil staining showed that the number of hippocampal nerve cells in rats increased, and they were closely arranged. The damage to the cell body was improved, and there was an increase in Nissl substances in the cells. The expression of TNF-α, IL-6, and IL-1ß in rat hippocampus decreased, and the expression of TP53, p-Akt1, and p-PI3K increased. The mechanism may be related to the activation of the PI3K-Akt signaling pathway and the inhibition of inflammatory response. Dabugan Decoction can play a good therapeutic and regulatory role in GAD, reflecting the overall effect of traditional Chinese medicine(TCM) compound and the characteristics of multiple targets and multiple pathways. At the same time, it is preliminarily discussed that the state of GAD may be improved by Dabugan Decoction via-activating PI3K-Akt signaling pathway and inhibiting inflammatory response and anti-apoptosis, thus providing experimental data support for the clinical application of Dabugan Decoction.

[Effects of Questionnaire-Based Psychological Survey Methods on the Evaluation Results in a Patient Cohort].

Objective To assess the influences of self-and interviewer-administered methods on the scores of anxiety and depression questionnaires among the patients with sports injuries.Methods A total of 532 participants with sports injuries treated in the Sports Medicine Center of West China Hospital,Sichuan University from November 2022 to May 2023 were included.They were randomly assigned to either the interviewer-administered group (n=270) or the self-administered group (n=262) to complete the generalized anxiety disorder (GAD-7) and the patient health questionnaire (PHQ-9) scales.The total scores and prevalence rates of anxiety and depression were compared between the two groups.Results There was no statistically significant difference in gender,occupation,or surgical site between the two groups (all P>0.05).The self-administered group had higher scores of GAD-7 and PHQ-9 scales than the interviewer-administered group (P<0.001,P<0.001).A greater proportion of participants in the self-administered group than in the interview-administered group met the criteria for mild to moderate anxiety and depression (P<0.001,P=0.002).The prevalence rates of moderate to severe anxiety (GAD-7≥10) and depression (PHQ-9≥10) showed no statistically significant difference between the two groups (P=0.761,P=0.086).Conclusion This study demonstrates that the participants in the self-administered group are more likely to report mild to moderate symptoms of anxiety and depression than those in the interviewer-administered group.

Prevalence of Generalized Anxiety Disorder in Japan: A General Population Survey.

Purpose: Generalized anxiety disorder (GAD) is among the most prevalent and highly disabling mental health conditions that negatively impacts patient's quality of life (QOL) and disrupts activities of daily living. However, the recognition of GAD is difficult due to substantial overlap with other mental disorders. The purpose of this study was to estimate the prevalence of GAD, assess QOL of probable GAD patients in Japan, and gain insights on the status of visiting medical institutions as well as their recognition/awareness of the disorder. Patients and Methods: We conducted a web-based cross-sectional survey of 20,009 participants using a questionnaire with approximately 30 single/multiple choice or open-ended questions in Japanese. Results: Overall prevalence of GAD based on Generalized Anxiety Disorder 7-item (GAD-7) cutoff score of ≥10 and questionnaires developed with reference to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria was 7.6% (n=1530) and 6.0% (n=1197), respectively. The degree of coincidence between GAD diagnosis by DSM-5 criteria and GAD-7 scores was moderate (Cohen's Kappa=0.47, p<0.01). Younger people reported a substantially higher prevalence of GAD compared to older. QOL scores assessed using EuroQol 5 dimensions 5-level and EuroQol Visual Analog Scale were substantially lower in probable GAD patients than those with GAD-7<10. Anxiety/depression and pain/discomfort were the most prevalent issues and depression was the most reported comorbidity for the probable GAD patients. Probable GAD patients "currently visiting medical institutions" for anxiety or other mental issues were 27.6% (422/1530); a majority had seen specialists. Most of the probable GAD patients had never heard of the disease. Conclusion: We found higher prevalence of GAD and lower QOL of probable GAD patients in Japan. There is a need for creating awareness about GAD among the general population and developing clinical guidelines on GAD in Japan so that physicians can educate their patients.

The Relationship between Metacognition, Rumination, and Sleep in University Students with a Tendency toward Generalized Anxiety Disorder.

People with generalized anxiety disorder tend to have sleep problems, and studies have found correlations between metacognition, rumination, and sleep, but it is unclear how metacognition and rumination work in people with a tendency towards generalized anxiety disorder. The goal of this paper is to investigate the correlation between metacognition, rumination, and sleep in university students with a tendency towards generalized anxiety disorder, and the mediating role of rumination in the effect of metacognition on sleep. The Generalized Anxiety Disorder Scale (GAD-7), the Meta-Cognition Questionnaire (MCQ-30), the Ruminative Responses Scale (RRS), and the Insomnia Severity Index (ISI) were used to investigate and psychometrically measure 566 university students in Anyang Normal College. The results of correlation analysis showed significant positive correlations between metacognition and sleep, ruminative thinking and sleep, and metacognition and rumination in university students with a tendency towards generalized anxiety disorder. Mediation analysis showed that rumination partially mediated the effect of metacognition on sleep, with the mediating effect accounting for 51.1% of the total effect. There is a strong correlation between metacognition, rumination, and sleep in university students with a tendency towards generalized anxiety disorder, and both metacognition and rumination can predict sleep, while metacognition can affect sleep through the mediating effect of rumination.

Sleep Health and Anxiety Symptoms in Midlife Women: The Study of Women's Health Across the Nation (SWAN).

Purpose: To investigate the associations between anxiety symptoms in midlife women and sleep features later in life, the aim is to test the hypothesis that poor sleep, as measured by each of six individual dimensions (4 objective actigraphy measures, 2 self-reports) of sleep health, is associated with higher levels of anxiety symptoms in midlife women. Participants and Methods: The participants in this longitudinal analysis included women from the SWAN Sleep I Study, a subcohort of the community-dwelling midlife women participating in the core Study of Women's Health Across the Nation (SWAN), which was initiated in 1996. Of the 370 participants enrolled in the Sleep Study, 270 were included in the analytic sample, and 100 who did not meet the inclusion criteria were excluded. Baseline measures of six dimensions of multidimensional sleep health (actigraphy measures: efficiency, duration, mid-sleep timing, regularity; self-report measures: alertness, satisfaction) were obtained between 2003 and 2005, corresponding to SWAN core annual/biennial assessments 5-8. Associations of each dimension with self-reported anxiety symptoms (Generalized Anxiety Disorder - 7-item scale; GAD-7), collected during visits 12 (2009-2011), 13 (2011-2013), and 15 (2015-2017), were examined using mixed models. The GAD-7 outcome was measured both continuously and as a categorical variable due to its skewed distribution. Results: No statistically significant associations were found between any of the six baseline sleep health dimensions and the GAD-7 score after adjustment for covariates. Conclusion: The reasons for the lack of support for our hypothesis, despite previous evidence supporting an association between sleep and anxiety, are unclear. There is considerable overlap between anxiety and sleep symptoms, which may complicate the interpretation of our the findings. Thus, the failure to identify associations is likely multifactorial, and more studies with shorter follow-up intervals are warranted to better understand these relationships.

Internet videoconferencing delivered cognitive behaviour therapy for generalized anxiety disorder: A randomized controlled trial.

OBJECTIVE: Generalized anxiety disorder (GAD) is a chronic mental health condition that results in significant individual and societal burden. Cognitive-behaviour therapy (CBT) therapy is an effective treatment for GAD, however, many individuals experience logistical barriers when accessing evidence-based care. Remote treatments may help to reduce these barriers, however, currently, there are few studies examining the efficacy of high-intensity remote methods for GAD treatment. The current study aims to examine the efficacy of CBT delivered via videoconferencing (VCBT) for GAD using a randomized controlled trial design comparing an immediate treatment group to a waitlist control. METHOD: Seventy-eight adults (Mage = 36.92; SD = 12.92; 84.4% female) with GAD were enrolled in the study. RESULTS: Those in the treatment group demonstrated a statistically significant reduction in GAD symptoms from pre-treatment to post-treatment (d = 1.03) and pre-treatment to 3-month follow-up (d = 1.50). Large between-group effect sizes were also observed at post-treatment (d = .80). Twenty-five participants (64.10%) in the VCBT group no longer met diagnostic criteria for GAD at post-treatment, and 26/39 (66.67%) no longer met criteria at 3-month follow-up. Ninety-six per cent of participants were satisfied with the treatment. CONCLUSION: The results contribute towards advancing our knowledge on the efficacy and acceptability of VCBT for patients with GAD.
