Development of an optimal short form of the GAD-7 scale with cross-cultural generalizability based on Riskslim.

Despite the relatively small number of items in the GAD-7, fewer items are increasingly sought to shorten testing time in large-scale mental health screenings. As a result, short forms based on the GAD-7, the GAD-2, and GAD-mini, have become popular. However, the GAD-2 and GAD-mini have reported lower diagnostic accuracy in some cultural contexts, implying that a validated short-form version of the GAD-7 may be lacking in large-scale cross-cultural anxiety screening. Based on this, to develop an optimal short form of the GAD-7 with cross-cultural stability, we utilized seven GAD-7 datasets from six different countries, totaling 47,484 participants. Five 2 to 6 item short forms of the GAD were constructed using the Riskslim machine learning algorithm. We evaluated the diagnostic accuracy of the GAD-7 short forms in the training and test sets based on the coefficient of determination(R2) and area under the curve(AUC) metrics, and the results showed that GAD-R2 performed poorly in some cultures, and all of the 3 to 6 item short forms of the GAD performed good in cross-cultural diagnostic rates, with the GAD-R6 showing the highest diagnostic accuracy in all cultures; GAD-R3 outperformed GAD-R2, GAD-2, and GAD-mini in all cultures; GAD-R3 had higher generalizability across cultures and special populations; Given that the GAD-R3 was shorter and nearly as accurate as the GAD-R6, we recommend the use of the GAD-R3 in clinical studies and epidemiologic investigations. And we recommend the optimal actual cutoff value of 15 for GAD-R3. Overall, we recommend GAD-R3 as the short-form version of GAD-7 in cross-cultural studies. However, the 2-item GAD scale is also optimal for the short-form version in clinical practice.

Can Muscular Parameters Predict Symptoms of Anxiety and Depression?

Major depressive disorder and anxiety disorders are among the major public health issues. Therefore, identifying predictors of symptoms of depression and anxiety holds fundamental importance to avoid the aggravation of these conditions. Muscle strength and function (e.g., handgrip strength and timed-stands test) are widely recognized predictors of health outcomes; however, their association with symptoms of depression and anxiety is still not completely understood. This study investigated the associations between handgrip strength and timed-stands test scores with symptoms of depression and anxiety. In addition, we examined whether individuals exhibiting greater strength levels demonstrate reduced symptoms of anxiety and depression compared to those with lower levels of strength. This is a community-based, cross-sectional study. Participants were recruited through social media and underwent a semi-structured interview to record sociodemographic characteristics, comorbidities, use of tobacco and medication, and symptoms of anxiety (Beck's Anxiety Inventory [BAI]) and depression (Beck's Depressive Inventory [BDI]). Subsequently, anthropometric characteristics, handgrip strength, and functionality (i.e., timed-stands test) were assessed. In all, 216 individuals were evaluated. The adjusted regression model showed an inverse association between handgrip strength and anxiety (ß = -0.22; 95% CI [-0.38, -0.07]; R2 = 0.07, p = .005) and depression symptoms (ß = -0.25; 95% CI [-0.42, -0.07]; R2 = 0.05, p = .006). Similarly, timed-stands test scores were associated with anxiety (ß = -0.33; 95% CI [-0.54, -0.13]; R2 = 0.09, p = .002) and depression (ß = -0.32; 95% CI [-0.56, -0.09]; R2 = 0.06, p = .008). Furthermore, the low-strength group showed higher values on the BAI (9.5 vs. 5.9 arbitrary units; p = .0008) and BDI than the high-strength group (10.8 vs. 7.9 arbitrary units; p = .0214). When individuals were stratified by the timed-stands test, the low timed-stands group demonstrated higher values on the BAI (9.9 vs. 5.5 arbitrary units; p = .0030) and BDI than the high timed-stands group (11.2 vs. 7.5 arbitrary units; p < .0001). The results highlight muscular parameters as significant predictors associated with anxiety and depression symptoms.

The relationship between the Hopkins symptom checklist-10 and diagnoses of anxiety and depression among inpatients with substance use disorders.

INTRODUCTION: The Hopkins Symptom Checklist-10 (HSCL-10) is a self-report inventory of anxiety and depression symptoms that may assist clinicians in screening for clinical conditions among patients with substance use disorder (SUD). We examined the HSCL-10 as a screening tool for anxiety and depressive disorders within a general population of SUD inpatients. METHODS: We used data from a cohort study of 611 SUD inpatients. Receiver operating characteristic (ROC) analyses were conducted, with and without covariates, to evaluate the potential of the HSCL-10 as a screening tool. This was explored using any anxiety disorder, especially posttraumatic stress disorder (PTSD), and any mood disorder, especially major depressive disorders, as the outcome criteria. Candidate covariates included gender, age, education, polydrug use and treatment center.Results: The HSCL-10 had a moderate ability to identify caseness (i.e. having or not having a clinical diagnosis) according to each outcome criterion, with the area under the ROC curve (AUC) varying from 0.64 to 0.66. Adding relevant covariates markedly enhanced the instrument's ability to identify those who met the criteria for any anxiety disorder (AUC = 0.77), especially PTSD (AUC = 0.82). CONCLUSION: In a real-world clinical setting, the HSCL-10 has fair-to-good clinical utility for identifying SUD inpatients who have comorbid clinical symptoms of anxiety disorders or PTSD, when combined with common background variables. The HSCL-10, a brief self-report screening tool, may serve as an efficient proxy for comprehensive interviews used in research and for clinical anxiety symptom screening among patients with SUD.

Lessons in clinical reasoning - pitfalls, myths, and pearls: a woman brought to a halt.

OBJECTIVES: Limitations in human cognition commonly result in clinical reasoning failures that can lead to diagnostic errors. A metacognitive structured reflection on what clinical findings fit and/or do not fit with a diagnosis, as well as how discordance of data can help advance the reasoning process, may reduce such errors. CASE PRESENTATION: A 60-year-old woman with Hashimoto thyroiditis, diabetes, and generalized anxiety disorder presented with diffuse arthralgias and myalgias. She had been evaluated by physicians of various specialties and undergone multiple modalities of imaging, as well as a electromyography/nerve conduction study (EMG/NCS), leading to diagnoses of fibromyalgia, osteoarthritis, and lumbosacral plexopathy. Despite treatment for these conditions, she experienced persistent functional decline. The only definitive alleviation of her symptoms identified was in the few days following intra-articular steroid injections for osteoarthritis. On presentation to our institution, she appeared fit with a normal BMI. She was a long-time athlete and had been training consistently until her symptoms began. Prediabetes had been diagnosed the year prior and her A1c progressed despite lifestyle modifications and 10 pounds of intentional weight loss. She reported fatigue, intermittent nausea without emesis, and reduced appetite. Examination revealed intact strength and range of motion in both the shoulders and hips, though testing elicited pain. She had symmetric hyperreflexia as well as a slowed, rigid gait. Autoantibody testing revealed strongly positive serum GAD-65 antibodies which were confirmed in the CSF. A diagnosis of stiff-person syndrome was made. She had an incomplete response to first-line therapy with high-dose benzodiazepines. IVIg was initiated with excellent response and symptom resolution. CONCLUSIONS: Through integrated commentary on the diagnostic reasoning process from clinical reasoning experts, this case underscores the importance of frequent assessment of fit along with explicit explanation of dissonant features in order to avoid misdiagnosis and halt diagnostic inertia. A fishbone diagram is provided to visually demonstrate the major factors that contributed to the diagnostic error. The case discussant demonstrates the power of iterative reasoning, case progression without commitment to a single diagnosis, and the dangers of both explicit and implicit bias. Finally, this case provides clinical teaching points in addition to a pitfall, myth, and pearl specific to overcoming diagnostic inertia.

Are Providers Adequately Screening for Anxiety Symptoms During Pregnancy?

OBJECTIVE: To examine the difference in prevalence of self-reported anxiety symptoms throughout pregnancy compared to clinical diagnosis of an anxiety disorder by a provider. DESIGN: Secondary data analysis of a prospective cohort study of 50 pregnant individuals. SETTING/LOCAL PROBLEM: Pregnant individuals commonly experience heightened anxiety symptoms, which are associated with adverse perinatal outcomes. However, a diagnosis of an anxiety disorder by a health care provider is less common, which may result in insufficient mental health intervention. PARTICIPANTS: Pregnant individuals were recruited at their first prenatal appointment and followed until birth. INTERVENTION/MEASUREMENTS: We examined anxiety symptoms using the Edinburgh Postnatal Depression Scale Anxiety subscale. We conducted a medical record review to examine if pregnant individuals were clinically diagnosed with an anxiety disorder. RESULTS: Based on an Edinburgh Postnatal Depression Scale Anxiety subscale cutoff score of ≥5, 40% (n = 20) of individuals experienced anxiety symptoms during pregnancy. However, only 16% (n = 8) of participants were diagnosed with an anxiety disorder by a health care provider. CONCLUSION: Anxiety symptoms are prevalent throughout pregnancy and may be underdiagnosed by health care providers. An intervention to increase clinical diagnosis of an anxiety disorder and subsequent referral to a mental health specialist may be indicated.

Prenatal mood and anxiety disorders and associated cytokine changes.

BACKGROUND: We examined whether women with prenatal mood and anxiety disorders would exhibit differential pro- and anti-inflammatory marker trajectories during the prenatal and postpartum periods compared to women without these disorders. METHODS: Approximately 179 pregnant women participated in a longitudinal study conducted in two urban areas. Blood samples for inflammatory markers were collected at six study visits. The Structured Clinical Interview for the DSM-IV (SCID) was administered to participants scoring above cutoffs on anxiety and depression. Pregnant women with SCID Axis I diagnoses of mood and/or anxiety disorders were compared to other participants on inflammatory markers. Multilevel modeling tested associations between SCID diagnoses and within-person interleukin (IL)6 and IL10 trajectories. RESULTS: Prenatal SCID diagnoses were associated with linear, quadratic and cubic change in IL6 from prenatal to postpartum timepoints. Women with a prenatal SCID diagnosis had steeper decreases and increases in IL6 during prenatal and postpartum periods. SCID diagnoses were associated with lower IL10 in mid-pregnancy to postpartum (b = -0.078, SE = 0.019; p = .015). LIMITATIONS: Future studies would benefit from a larger sample size and a larger number of participants with SCID diagnoses. Future research should also examine whether different prenatal Axis 1 diagnoses are associated with different patterns of immune response in pregnancy. CONCLUSIONS: Pregnant women with prenatal mood and anxiety disorders had greater fluctuations in IL6 across prenatal and postpartum periods and lower IL10 through pregnancy and postpartum. They may have different proinflammatory states that remain after birth without a reciprocal anti-inflammatory response.

Screening and Follow-Up Care for Perinatal Mood and Anxiety Disorders at a Rural Obstetric Clinic.

OBJECTIVE: To improve screening for perinatal mood and anxiety disorders (PMAD) and follow-up care while balancing team workload. DESIGN: Four rapid plan-do-study-act cycles were implemented over 8 weeks. SETTING/LOCAL PROBLEM: At baseline, only 2% of patients with PMAD were identified at a rural obstetric clinic, and none (n = 0 of 50) received screening with a validated tool. Of the 12 patients who had a current or prior history of PMAD, 92% (n = 11) were not screened for self-harm, and 67% (n = 8) received no referral. The clinic had no standardized care for PMAD. PARTICIPANTS: Patients (n = 253) screened at initial pregnancy intake, early in the third trimester, and at the 6-week postpartum visit. INTERVENTION/MEASUREMENTS: Following the screening, brief intervention, and referral to treatment model, patients were screened using the Edinburgh Postnatal Depression Scale, and brief intervention and referral to treatment were used with a point-of-care checklist. Data were collected three times weekly for run chart analysis, and team surveys measured workload. RESULTS: At the end of 8 weeks, effective screening for PMAD and follow-up care were achieved for 98% of patients and included screening, education, shared decision-making for management, referral, and clinic and phone follow-up to support mental health care uptake. CONCLUSIONS: Standardizing screening and follow-up care can increase identification of PMAD and increase uptake of mental health care. For sustainability, a decision aid can streamline patient-provider communication and reduce visit length.

Can EPDS and EPDS-3A be used to replace GAD-7 to screen the anxiety of pregnant women during pregnancy examination?

OBJECTIVE: To examine the screening ability and cut-off scores of the Edinburgh Postnatal Depression Scale (EPDS) and EPDS-3A for pregnancy anxiety in pregnancy examination. METHODS: This was a prospective repetitive measurement study. A follow-up survey was performed in Chinese pregnant women with the EPDS, the 7-item Generalized Anxiety Disorder (GAD-7) scale and a basic information questionnaire. A total of 609 women participated in all surveys at three trimesters, and all data were complete with no missing values. Receiver operating characteristic curves, Cohen's kappa and cross-tabulation were used to test the single and combined screening ability of EPDS and EPDS-3A for pregnancy anxiety. RESULTS: The areas under the curves of EPDS and EPDS-3A were close to or more than 0.90. EPDS scores greater than 14 in the first trimester and greater than 13 in the second and third trimesters could be used as the cut-off values. EPDS-3A score greater than 4 could be used as the cut-off value in each trimester. Adding the EPDS-3A to the EPDS would lead to correct identification of an additional 6.33%, 6.35%, and 7.25% of anxious women and misdiagnosis of an additional 6.60%, 2.56%, and 2.41% of normal women in each trimester, respectively. CONCLUSION: The EPDS and EPDS-3A can be used alone or in combination for initially screening of pregnancy anxiety. Under certain conditions, they can even be used to replace GAD-7 for anxiety screening to reduce the adverse influence of excessive screening on pregnant women, and improve the quality of survey data and efficiency of clinical services.

Identification of depression and anxiety during pregnancy: A systematic review and meta-analysis of test accuracy.

INTRODUCTION: Depression and anxiety are significant contributors to maternal perinatal morbidity and a range of negative child outcomes. This systematic review and meta-analysis aimed to review and assess the diagnostic test accuracy of selected screening tools (Edinburgh Postnatal Depression Scale [EPDS], EPDS-3A, Patient Health Questionnaire [PHQ-9]-, PHQ-2, Matthey Generic Mood Question [MGMQ], Generalized Anxiety Disorder scale [GAD-7], GAD-2, and the Whooley questions) used to identify women with antenatal depression or anxiety in Western countries. MATERIAL AND METHODS: On January 16, 2023, we searched 10 databases (CINAHL, Cochrane Library, CRD Database, Embase, Epistemonikos, International HTA Database, KSR Evidence, Ovid MEDLINE, PROSPERO and PsycINFO); the references of included studies were also screened. We included studies of any design that compared case-identification with a relevant screening tool to the outcome of a diagnostic interview based on the Diagnostic and Statistical Manual of Mental Disorders, fourth or fifth edition (DSM-IV or DSM-5), or the International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD-10). Diagnoses of interest were major depressive disorder and anxiety disorders. Two authors independently screened abstracts and full-texts for relevance and evaluated the risk of bias using QUADAS-2. Data extraction was performed by one person and checked by another team member for accuracy. For synthesis, a bivariate model was used. The certainty of evidence was assessed using Grading of Recommendations Assessment, Development and Evaluation (GRADE). REGISTRATION: PROSPERO CRD42021236333. RESULTS: We screened 8276 records for eligibility and included 16 original articles reporting on diagnostic test accuracy: 12 for the EPDS, one article each for the GAD-2, MGMQ, PHQ-9, PHQ-2, and Whooley questions, and no articles for the EPDS-3A or GAD-7. Most of the studies had moderate to high risk of bias. Ten of the EPDS articles provided data for synthesis at cutoffs ≥10 to ≥14 for diagnosing major depressive disorder. Cutoff ≥10 gave the optimal combined sensitivity (0.84, 95% confidence interval [CI]: 0.75-0.90) and specificity (0.87, 95% CI: 0.79-0.92). CONCLUSIONS: Findings from the meta-analysis suggest that the EPDS alone is not perfectly suitable for detection of major depressive disorder during pregnancy. Few studies have evaluated the other instruments, therefore, their usefulness for identification of women with depression and anxiety during pregnancy remains very uncertain. At present, case-identification with any tool may best serve as a complement to a broader dialogue between healthcare professionals and their patients.

Depression and anxiety in patients with head and neck cancer undergoing free flap reconstruction.

PURPOSE: To determine the prevalence and severity of depression and anxiety in patients with head and neck cancer (HNC) undergoing treatment with free-flap (FF) reconstruction. METHODS: Participants with HNC undergoing FF reconstruction were given the validated 9-item Patient Health Questionnaire (PHQ-9) and a 7-item Generalized Anxiety Disorder (GAD-7) questionnaire prior to surgery. Patient factors and responses were analyzed. RESULTS: Seventy-one patients were included. Mean (SD) pre-operative PHQ-9 was 7.6 (7.04) with 34 % (n = 24) having moderate to severe depression. Mean (SD) pre-operative GAD-7 was 6.5 (6.86) with 30 % (n = 21) having moderate to severe anxiety. CONCLUSION: Prevalence of depression and anxiety is high in this cohort and undiagnosed in 22 % and 18 % of patients, respectively. Due to the findings, it is prudent to screen HNC patients at initial diagnosis and offer mental health services.

Determining the optimal cut-off scores for the Chinese version of the Memorial Anxiety Scale for Prostate Cancer (MAX-PC).

PURPOSE: Anxiety is a common emotion experienced by patients with prostate cancer (PCa), and can be exacerbated by testing the prostate-specific antigen (PSA) index. The Memorial Anxiety Scale for Prostate Cancer (MAX-PC) was developed to assess the cancer-specific anxiety of these patients, but lack of appropriate thresholds for this scale limits its use. This study aimed to utilize ROC curve analysis to identify the best cut-off values for the Chinese version of the MAX-PC scale. METHODS: A cross-sectional survey was conducted using the Chinese version of the MAX-PC scale and the Generalized Anxiety Disorder Scale (GAD). ROC curve analysis, Youden index, Kappa consistency test and McNemar test were used for the optimal cutoff points for screening mild, moderate, and severe cancer-specific anxiety levels in patients with PCa, on the Chinese version of the MAX-PC scale. RESULTS: Two hundred eighty-seven patients with PCa completed the survey. The appropriate cut-off values for the MAX-PC scale for screening patients with PCa for cancer-specific anxiety were 20, 28, and 38 for mild, moderate, and severe anxiety, respectively with the highest Youden indices. The Kappa and McNemar's test showed the best level of consistency with values of 0.627, 0.580, and 0.606 for screening mild, moderate, and severe anxiety, respectively. CONCLUSIONS: The scores 20, 28, and 38 are the best cut-off values for the Chinese version of the MAX-PC scale. This scale should be used for screening cancer-specific anxiety for patients with PCa to assess and evaluate their anxiety levels and provide targeted interventions.

Association between anxiety and depression and all-cause mortality: a 50-year follow-up of the Population Study of Women in Gothenburg, Sweden.

OBJECTIVES: This study aimed to examine the association between anxiety disorders and/or major depression disorder (ADs/MDD) and all-cause mortality in a 50-year perspective and to examine specific risk and health factors that may influence such an association. DESIGN: Observational population study, 1968-2019. SETTING: The Population Study of Women in Gothenburg, Sweden (PSWG). PARTICIPANTS: In 1968-1969, 899 (out of 1462) women from PSWG were selected according to date of birth for a psychiatric investigation, including diagnostic evaluation. Eight hundred (89%) were accepted. Twenty-two women were excluded. Of the 778 included, 135 participants (17.4 %) had solely ADs, 32 (4.1%) had solely MDD and 25 (3.2%) had comorbid AD/MDD. PRIMARY AND SECONDARY OUTCOME MEASURES: Associations between ADs, MDD, comorbid AD/MDD and all-cause mortality with adjustments for potential confounding factors. Differences between the groups concerning health and risk factors and their association with mortality. RESULTS: In a fully adjusted model, ADs were non-significantly associated with all-cause mortality (HR 1.17, 95% CI 0.98 to 1.41). When examining age during risk time as separate intervals, a significant association between mortality and AD was seen in the group of participants who died at the age of 65-80 years (HR 1.70, 95% CI 1.26 to 2.29). In the younger or older age interval, the association did not reach significance at the 95% level of confidence. Among confounding factors, smoking and physical activity were the strongest contributors. The association between smoking and mortality tended to be further increased in the group with ADs versus the group without such disorders (HR 2.10, 95% CI 1.60 to 2.75 and HR 1.82, 95% CI 1.56 to 2.12, respectively). CONCLUSIONS: This study suggests potential links between ADs, age and mortality among women with 50 years of follow-up, but does not provide definitive conclusions due to the borderline significance of the results.

Improving Mental Health Outcomes in Adolescent Patients With Universal Anxiety Screening in an Outpatient Pediatric Primary Care Office: A Quality Improvement Project.

INTRODUCTION: In the wake of the cultural and mental health consequences that arose since the COVID-19 pandemic, primary care providers must be able to assess and initiate treatment of anxiety disorders in the pediatric population. Only 59% of children with a diagnosable anxiety disorder are identified and receive treatment. This quality improvement project aimed to evaluate the implementation of universal anxiety screening using the General Anxiety Disorder-7 tool in pediatric primary care. METHODS: Screening was performed on adolescents (aged 12-18 years) to evaluate the frequency and acceptability of tool administration and identification of anxiety and referrals to mental health care for treatment. Employing a pretest-posttest design, the effect of universal anxiety screening for adolescents was measured at well-child visits. RESULTS: Anxiety screening and anxiety diagnosis rates were significantly increased post-implementation. DISCUSSION: Universal screening for anxiety was efficacious in the project setting for identifying cases of anxiety.

Proctological disorders: psychometrics assessment of personality features and clinical evaluation.

Patients with gastrointestinal diseases have been shown to report greater stress, anxiety, depression and obsessive-compulsive characteristics. The aim of our study is to investigate personality characteristics and general distress of adult patients suffering from common coloproctological conditions. We conducted a retrospective observational study including patients aged 18 years or older, with diagnosis of haemorrhoidal disease (HD group) or anal fissure (AF group). The final sample was composed of 64 participants, who were asked to complete a battery of questionnaires. They were compared with a control group of healthy volunteers. In terms of general distress, HD group scored higher than both the CG and AF groups. The two proctological groups had higher scores in neuroticism/emotional lability compared to the CG group. In the MOCQ-R scale (obsessive-compulsive tendency), HD group had significantly higher scores compared to the CG group in the total score (p < 0.01,) and also scored higher in the doubting/ruminating subscale compared to the AF group. We support the importance of taking a multidisciplinary perspective and incorporating psychometric tools to assess the psychological and personality dimensions of patients into proctological clinical practice. The correct early evaluation and management of these conditions may result in an improvement in patients' quality of life and better response to treatment.

Screening for Anxiety Disorders in Adults: US Preventive Services Task Force Recommendation Statement.

Importance: Anxiety disorders are commonly occurring mental health conditions. They are often unrecognized in primary care settings and substantial delays in treatment initiation occur. Objective: The US Preventive Services Task Force (USPSTF) commissioned a systematic review to evaluate the benefits and harms of screening for anxiety disorders in asymptomatic adults. Population: Asymptomatic adults 19 years or older, including pregnant and postpartum persons. Older adults are defined as those 65 years or older. Evidence Assessment: The USPSTF concludes with moderate certainty that screening for anxiety disorders in adults, including pregnant and postpartum persons, has a moderate net benefit. The USPSTF concludes that the evidence is insufficient on screening for anxiety disorders in older adults. Recommendation: The USPSTF recommends screening for anxiety disorders in adults, including pregnant and postpartum persons. (B recommendation) The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for anxiety disorders in older adults. (I statement).

Anxiety Screening: Evidence Report and Systematic Review for the US Preventive Services Task Force.

Importance: Anxiety is commonly seen in primary care and associated with substantial burden. Objective: To review the benefits and harms of screening and treatment for anxiety and the accuracy of instruments to detect anxiety among primary care patients. Data Sources: MEDLINE, PsychINFO, Cochrane library through September 7, 2022; references of existing reviews; ongoing surveillance for relevant literature through November 25, 2022. Study Selection: English-language original studies and systematic reviews of screening or treatment compared with control conditions and test accuracy studies of a priori-selected screening instruments were included. Two investigators independently reviewed abstracts and full-text articles for inclusion. Two investigators independently rated study quality. Data Extraction and Synthesis: One investigator abstracted data; a second checked accuracy. Meta-analysis results were included from existing systematic reviews where available; meta-analyses were conducted on original research when evidence was sufficient. Main Outcomes and Measures: Anxiety and depression outcomes; global quality of life and functioning; sensitivity and specificity of screening tools. Results: Of the 59 publications included, 40 were original studies (N = 275 489) and 19 were systematic reviews (including ≈483 studies [N≈81 507]). Two screening studies found no benefit for screening for anxiety. Among test accuracy studies, only the Generalized Anxiety Disorder (GAD) GAD-2 and GAD-7 screening instruments were evaluated by more than 1 study. Both screening instruments had adequate accuracy for detecting generalized anxiety disorder (eg, across 3 studies the GAD-7 at a cutoff of 10 had a pooled sensitivity of 0.79 [95% CI, 0.69 to 0.94] and specificity of 0.89 [95% CI, 0.83 to 0.94]). Evidence was limited for other instruments and other anxiety disorders. A large body of evidence supported the benefit of treatment for anxiety. For example, psychological interventions were associated with a small pooled standardized mean difference of -0.41 in anxiety symptom severity in primary care patients with anxiety (95% CI, -0.58 to -0.23]; 10 RCTs [n = 2075]; I2 = 40.2%); larger effects were found in general adult populations. Conclusions and Relevance: Evidence was insufficient to draw conclusions about the benefits or harms of anxiety screening programs. However, clear evidence exists that treatment for anxiety is beneficial, and more limited evidence indicates that some anxiety screening instruments have acceptable accuracy to detect generalized anxiety disorder.

[Research advances in the correlation between chronic subjective tinnitus and anxiety state].

Tinnitus and anxiety disorder are common clinical symptoms. Comorbidity between tinnitus and anxiety state is increasing year by year. The relationship between tinnitus and anxiety state has always been a hot topic, and this paper reviews the literature on the relationship between chronic subjective tinnitus and anxiety state in recent years.

[Association of depression and anxiety with somatic diseases: negative lifestyle factors impact]. / Svyaz' depressii i trevogi s somaticheskimi zabolevaniyami: rol' negativnykh vneshnikh faktorov.

OBJECTIVE: To assess the associations of various depression and anxiety phenotypes with manifestations of different somatic disorders and negative lifestyle factors. MATERIAL AND METHODS: The study involved 5116 people. In the online questionnaire, participants provided information about age, sex, height and weight, as well as a history of smoking, alcohol use, physical activity and diagnoses/symptoms of various physical diseases. Self-questions based on the DSM-5 criteria and the online version of the HADS were used to screen for phenotypes of affective and anxiety disorders in a population sample. RESULTS: An association of both subclinical and clinical depressive symptoms on HADS-D was noted for respondents with weight gain (OR 1.43; CI: 1.29-1.58, p<0.05 and OR 1,CI: 1.05-1.52, p<0.05, respectively), increased BMI (OR 1.36; CI: 1.24-1.48, p<0.05 OR 1.27; CI: 1.09-1.47, p<0.05 respectively), and decreased physical activity (OR 1.67; CI: 1.35-2.07, p<0.05 and OR 2.35; CI: 1.59-3.57, p<0.05, respectively) at the time of testing. The phenotypes of depression, anxiety disorders, and bipolar disorder by DSM criteria were associated with a history of smoking. (OR 1.37; CI: 1.18-1.62, p<0.001; OR 1.36; CI: 1.24-1.48, p<0.05 and OR 1.59; CI: 1.26-2.01, p<0.001, respectively). For higher BMI the association was reported only for the bipolar depression phenotype (OR 1.16; CI: 1.04-1.29, p<0.05), and with a decrease in physical activity - for the phenotypes of major depression and anxiety disorders (OR 1.27; CI: 1.07-1.52, p<0.05 and OR 1.61; CI: 1.31-1.99, p<0.001, respectively). A significant association with various somatic disorders was noted for all phenotype variants, but to the greatest extent for those based on DSM criteria. CONCLUSIONS: The study confirmed the association of negative external factors and various somatic disorders with depression. These associations were noted for various phenotypes of anxiety and depression, both in severity and structure, and may be due to complex mechanisms that have shared biological and environmental mechanisms.
