Intrarelationships between suboptimal health status and anxiety symptoms: A network analysis

BACKGROUND

Suboptimal health status is a global public health concern of worldwide academic interest, which is an intermediate health status between health and illness. The purpose of the survey is to investigate the relationship between anxiety statuses and suboptimal health status and to identify the central symptoms and bridge symptoms.

METHODS

This study recruited 26,010 participants aged <60 from a cross-sectional study in China in 2022. General Anxiety Disorder-7 (GAD-7) and suboptimal health status short form (SHSQ-9) were used to quantify the levels of anxiety and suboptimal health symptoms, respectively. The network analysis method by the R program was used to judge the central and bridge symptoms. The Network Comparison Test (NCT) was used to investigate the network differences by gender, place of residence, and age in the population.

RESULTS

In this survey, the prevalence of anxiety symptoms, SHS, and comorbidities was 50.7 %, 54.8 %, and 38.5 %, respectively. "Decreased responsiveness", "Shortness of breath", "Uncontrollable worry" were the nodes with the highest expected influence. "Irritable", "Exhausted" were the two symptom nodes with the highest expected bridge influence in the network. There were significant differences in network structure among different subgroup networks.

LIMITATIONS

Unable to study the causal relationship and dynamic changes among variables. Anxiety and sub-health were self-rated and may be limited by memory bias.

CONCLUSIONS

Interventions targeting central symptoms and bridge nodes may be expected to improve suboptimal health status and anxiety in Chinese residents. Researchers can build symptom networks for different populations to capture symptom relationships.

Perceived Need for Mental Health Care in a Cohort of Persons With Inflammatory Bowel Disease

BACKGROUND

Psychiatric comorbidity is common in inflammatory bowel disease (IBD) and can negatively affect disease outcomes. We explored the perceived need for mental health care among persons with IBD.

STUDY

Persons with IBD completed self-report questionnaires, including the Hospital Anxiety and Depression Scale (HADS), and reported whether they wanted help with their mood. Each was also assessed using the Structured Clinical Interview for DSM-IV-TR Axis-I Disorders (SCIDs). We used logistic regression analyses to determine factors associated with the perceived need for mental health care.

RESULTS

Of 245 participants, 28% met the criteria for a past diagnosis of depression or anxiety disorder by SCID, and nearly 23% met the criteria for a current diagnosis of depression or anxiety disorder. One-third (n = 74) reported a perceived need for mental health care. Among those meeting criteria for a current SCID diagnosis of depression or anxiety, only 58% reported needing mental health care. Need for mental health care was reported by 79% of persons currently treated for either depression or 71% treated for anxiety. Persons with a perceived need for mental health care had higher mean HADS for depression and HADS for anxiety scores and also higher IBD symptom activity scores. Of those reporting no perceived need for mental health care, 13% had a current diagnosis of depression or anxiety disorder by SCID; even fewer had symptoms of depression or anxiety.

CONCLUSIONS

Symptoms of depression or anxiety are more important than a formal diagnosis of depression or anxiety in predicting which persons with IBD will perceive a need for mental health care.

Do depressive and anxiety symptoms influence the construct validity of Multiple Sclerosis Walking Scale-12 scores?

PURPOSE/OBJECTIVE

Walking dysfunction, depression, and anxiety are prevalent, burdensome, and interrelated outcomes in persons with multiple sclerosis (MS). The 12-item Multiple Sclerosis Walking Scale (MSWS-12) is a common patient-reported outcome (PRO) of walking dysfunction in research and practice involving MS, but the construct validity of its scores might be influenced by symptoms of depression and anxiety. This study examined if symptoms of depression and anxiety influenced the construct validity of MSWS-12 scores.

RESEARCH METHOD/DESIGN

The sample included 189 participants with MS who completed the MSWS-12, Hospital Anxiety and Depression Scale (HADS-Depression subscale [HADS-D] and HADS-Anxiety subscale [HADS-A]), 6-minute walk (6MW), and timed 25-foot walk (T25FW). We conducted bivariate correlation analysis to examine the associations between MSWS-12 scores and both the 6MW and T25FW, while controlling for HADS-D and HADS-A scores.

RESULTS

MSWS-12 scores were significantly correlated with the 6MW (r = -.752), T25FW (r = .694), HADS-D (r = .405), and HADS-A (r = .235). The correlations between MSWS-12 and 6MW (pr = -.725) and T25FW (pr = .685) did not change when controlling for HADS-D and HADS-A scores. The correlations between MSWS-12 and 6MW (r = -.708 and r = -.726) and T25FW (r = .687 and r = .748) were strong in subsamples with elevated HADS-D and HADS-A scores.

CONCLUSIONS/IMPLICATIONS

Our results strengthen the validity evidence for MSWS-12 scores as a PRO of walking dysfunction in MS, including among those with symptoms of depression and anxiety. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Prevalence and factors associated with depression and anxiety among young school-going adolescents in the Western Cape Province of South Africa

INTRODUCTION

Between 10 and 20% of children and adolescents globally experience common mental health conditions such as depression or anxiety. Given the dearth of mental health services in low- and middle-income countries, most mental health conditions among adolescents remain undiagnosed and untreated. In South Africa, few studies have explored the prevalence of depression and anxiety among young adolescents aged 10-14 years. This study examined the prevalence of, and factors associated with depression and anxiety among young school-going adolescents in the Western Cape Province of South Africa.

METHODS

A cross-sectional study was conducted in 10 schools in the Western Cape Province from February to July 2022. Data were collected using a tablet-based survey and included sociodemographic items, the Generalized Anxiety Disorder 7-item scale (GAD-7), the Patient Health Questionnaire for Adolescents (PHQ-A) and other psychosocial measures. The prevalence of depression and anxiety was estimated based on cut-off scores for the GAD-7 and PHQ-A. Multivariable logistic regression models were used to investigate the associations between sociodemographic and psychosocial factors, and depression and anxiety.

RESULTS

Of the 621 adolescents, 33.5% (n = 208) reported experiencing symptoms of depression and 20.9% (n = 130) symptoms of anxiety potentially indicative of a diagnosis. The results of the multivariable logistic regression model indicate that being in a higher grade in school (AOR = 1.65, CI:1.43-1.92), any lifetime alcohol use (AOR = 1.62, CI:1.04-2.64), other drug use (AOR = 2.07, CI:1.06-4.04), and witnessing violence among adults at home (AOR = 2.12, CI:1.07-1.41) were significantly associated with experiencing depressive symptoms. Being in a higher grade in school (AOR = 1.69, CI: 1.42-2.01), poor emotional regulation skills (AOR = 1.03, CI: 1.00-1.07), and the use of cannabis (AOR = 1.03, CI: 1.00-1.07) were significantly associated with experiencing anxiety symptoms.

CONCLUSION

These findings add to our understanding of school-going adolescents' pressing mental health needs and suggest that mental health adolescent and caregiver interventions may be required to address mental health symptoms and associated risk factors.

Unraveling the distinction between depression and anxiety: A machine learning exploration of causal relationships

OBJECTIVE

Depression and anxiety, prevalent coexisting mood disorders, pose a clinical challenge in accurate differentiation, hindering effective healthcare interventions. This research addressed this gap by employing a streamlined Symptom Checklist 90 (SCL-90) designed to minimize patient response burden. Utilizing machine learning algorithms, the study sought to construct classification models capable of distinguishing between depression and anxiety.

METHODS

The study included 4262 individuals currently experiencing depression alone (n = 2998), anxiety alone (n = 716), or both depression and anxiety (n = 548). Counterfactual diagnosis was used to construct a causal network on the dataset. Employing a causal network, the SCL-90 was simplified. Items that have causality with only depression, only anxiety and both depression and anxiety were selected, and these streamlined items served as input features for four distinct machine learning algorithms, facilitating the creation of classification models for distinguishing depression and anxiety.

RESULTS

Cross-validation demonstrated the performance of the classification models with the following metrics: (1) K-nearest neighbors (AUC = 0.924, Acc = 92.81 %); (2) support vector machine (AUC = 0.937, Acc = 94.38 %); (3) random forest (AUC = 0.918, Acc = 94.38 %); and (4) adaptive boosting (AUC = 0.882, Acc = 94.38 %). Notably, the support vector machine excelled, with the highest AUC and superior accuracy.

CONCLUSION

Incorporating the simplified SCL-90 and machine learning presents a promising, efficient, and cost-effective tool for the precise identification of depression and anxiety.

The comorbid network characteristics of anxiety and depressive symptoms among Chinese college freshmen

BACKGROUND

This study aimed to investigate the interplay between anxiety and depressive symptoms in Chinese college freshmen using the causal system perspective (CSP), which differs from the traditional common cause perspective (CCP) by providing an alternative explanation by attributing comorbidity to direct interactions among symptoms.

METHODS

A convenience sample of 2,082 Chinese college freshmen (39.51% male, Mage = 18.61) from a normal university completed the Generalized Anxiety Disorder 7-Item Scale (GAD-7) and the Patient Health Questionnaire (PHQ-9). Network analysis was conducted and evaluated as to centrality, stability, node predictability, and bridging features. Moreover, the moderated network model (MNM) was utilized to detect the moderation effects of gender in the comorbidity network.

RESULTS

The network of anxiety and depressive symptoms exhibited stability, characterized by the core symptoms of "restlessness", "lack of energy", and "excessive worry about control", as well as the bridging symptoms of "fearfulness", "sad mood", and "irritability". Notably, the nodes representing "uncontrollable worry" and "difficulty in relaxation" demonstrated the highest predictive power. Gender did not exert any moderating effects on the anxiety and depressive symptom network.

CONCLUSION

These results reinforce that certain anxiety or depressive symptoms are more central than others, and thus play a more vital role in the comorbid network. These findings highlight underlying potential targeting symptoms to consider in future interventions.

Polysomnographic features of insomnia occurring in major depressive disorder, generalized anxiety disorder and bipolar mania: Comparison with primary insomnia and association with metabolic indicators

BACKGROUND

Insomnia is very common in psychiatric disorders, but the polysomnographic (PSG) characteristics of insomnia in various psychiatric disorders are still not agreed upon. This study aimed to investigate the characteristics of PSG and its relationship with metabolic indicators in insomnia patients with affective disorders and primary insomnia (PI) patients.

METHODS

A total of 38 patients with PI, 44 major depressive disorder patients with insomnia (DI), 49 generalized anxiety disorder patients with insomnia (GI), and 19 bipolar mania patients with insomnia (BI) were included. PSG was used to detect sleep problems in subjects, and biochemical indicators were also collected.

RESULTS

The results of this study found that subjects with BI were lower on REM sleep latency (RL), awakenings number (AN), number of microarousals (NM), and apnea-hypopnea index (AHI) than those with DI and GI, and lower on RL and AN than those with PI. Subjects with PI had lower NM and AHI than those with DI and GI. Patients with DI had a higher RL than those with GI. All results passed Bonferroni correction (p < 0.00078). No differences in biochemical indices were found among the four groups of subjects. Also, AHI was found to be positively correlated with free triiodothyronine (FT3) and fasting blood glucose in subjects.

CONCLUSION

This study suggests that various psychiatric disorders may have their characteristics in terms of PSG parameters, which prompted us to focus on the PSG characteristics of these disorders when assessing them, as well as to focus on their biochemical indicators.

Aerobic exercise during adolescence and anxiety disorders in adulthood: A cohort study using Add Health

INTRODUCTION

The prevalence of anxiety disorders, and mental chronic diseases, has increased over the last decade among adolescents. Since aerobic exercise reduces the risk of chronic diseases and stress symptoms, we aimed to examine the association between aerobic exercise in adolescence and anxiety disorders in adulthood.

METHODS

Self-reported, publicly available data from 5,114 adolescents who participated in Waves I and IV of the National Longitudinal Study of Adolescent Health (Add Health) was analyzed from 1994-2009. We included US-based individuals aged 16 years on average and observed them for 15 years. Weighted Poisson regression models estimated the association between aerobic exercise in Wave I (1994, baseline) and anxiety disorders in Wave IV (2009, adulthood), adjusting for sociodemographic characteristics and substance use at baseline.

RESULTS

Overall, 639/5,114 (weighted 12.96%) individuals experienced anxiety disorders at baseline. Age and sex differed significantly across all exercise groups (p's<0.001). Aerobic exercise did not significantly protect against anxiety disorders in adulthood: compared to adolescents who did not exercise at all, those who exercised 1-2 times/week had 0.85 times the prevalence of anxiety disorders during adulthood (95% CI = 0.65, 1.12; p = 0.25). Those who exercised 3-4 times/week had 0.81 times the prevalence (95% CI = 0.61, 1.08, p = 0.15) and those who exercised 5+ times/week had 0.84 times the prevalence (95% CI = 0.63, 1.13, p = 0.25) than those who did not exercise at all.

CONCLUSION

Aerobic Exercise in adolescence did not protect against anxiety disorders in adulthood. More evidence is needed on this association, including using homogeneous measures of exercise and repeated measures methods.

Assessment of perinatal anxiety: diagnostic accuracy of five measures

BACKGROUND

Anxiety in pregnancy and after giving birth (the perinatal period) is highly prevalent but under-recognised. Robust methods of assessing perinatal anxiety are essential for services to identify and treat women appropriately.

AIMS

To determine which assessment measures are most psychometrically robust and effective at identifying women with perinatal anxiety (primary objective) and depression (secondary objective).

METHOD

We conducted a prospective longitudinal cohort study of 2243 women who completed five measures of anxiety and depression (Generalized Anxiety Disorder scale (GAD) two- and seven-item versions; Whooley questions; Clinical Outcomes in Routine Evaluation (CORE-10); and Stirling Antenatal Anxiety Scale (SAAS)) during pregnancy (15 weeks, 22 weeks and 31 weeks) and after birth (6 weeks). To assess diagnostic accuracy a sample of 403 participants completed modules of the Mini-International Neuropsychiatric Interview (MINI).

RESULTS

The best diagnostic accuracy for anxiety was shown by the CORE-10 and SAAS. The best diagnostic accuracy for depression was shown by the CORE-10, SAAS and Whooley questions, although the SAAS had lower specificity. The same cut-off scores for each measure were optimal for identifying anxiety or depression (SAAS ≥9; CORE-10 ≥9; Whooley ≥1). All measures were psychometrically robust, with good internal consistency, convergent validity and unidimensional factor structure.

CONCLUSIONS

This study identified robust and effective methods of assessing perinatal anxiety and depression. We recommend using the CORE-10 or SAAS to assess perinatal anxiety and the CORE-10 or Whooley questions to assess depression. The GAD-2 and GAD-7 did not perform as well as other measures and optimal cut-offs were lower than currently recommended.

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.

Comparisons between atypical anorexia nervosa and anorexia nervosa: Psychological and comorbidity patterns

OBJECTIVE

Literature comparing "atypical" anorexia nervosa (atypical AN) and anorexia nervosa (AN) suggests these diagnoses share significant similarities in eating disorder (ED) pathology and psychiatric comorbidities. This study evaluated potential differences in ED pathology, psychiatric comorbidity, associated mechanisms (i.e., ED fears and perfectionism), and demographic factors (i.e., ethnicity and age) between individuals with atypical AN and AN.

METHOD

Data from seven protocols were combined for a total 464 individuals diagnosed with atypical AN (n = 215) or AN (n = 249). Between-group differences in ED severity and behaviors, psychiatric comorbidities, ED fears, perfectionism, and demographic factors were assessed using t-tests, Wilcoxon rank-sum tests, and Fisher's exact test.

RESULTS

Participants with atypical AN reported higher levels of overvaluation of weight and shape than those with AN. Participants with AN scored higher on food-related fears (anxiety about eating, food avoidance behaviors, and feared concerns) and fears of social eating, as well as obsessive-compulsive symptoms. Participants with AN were more likely to identify as Asian or Pacific Islander. No other statistically significant differences were found between groups for overall ED severity, ED behaviors, psychiatric comorbidities, general ED fears, perfectionism, or demographic factors.

DISCUSSION

Overall, results support previous literature indicating limited differences between individuals with atypical AN and AN, though individuals with atypical AN reported more overvaluation of weight and shape and those with AN reported higher food and social eating fears and obsessive-compulsive symptoms. Relatively few overall differences between atypical AN and AN highlight the importance of exploring dimensional conceptualizations of AN as an alternative to the current categorical conceptualization.

PUBLIC SIGNIFICANCE

This study assessed differences among individuals with atypical anorexia nervosa and anorexia nervosa in eating disorder severity and behaviors, comorbid psychiatric diagnoses, associated mechanisms, and demographic factors. Few differences emerged, though participants with atypical anorexia nervosa reported more overvaluation of weight and shape, while those with anorexia nervosa reported more food and social eating fears and higher obsessive-compulsive symptoms. Results support exploration of these diagnoses as a spectrum disorder.

Annual Research Review: Health anxiety in children and adolescents-developmental aspects and cross-generational influences

Health anxiety involves excessive worries about one's health along with beliefs one has an illness or may contract a serious disease. Concerning evidence suggests that health anxiety is on the rise in society, possibly further fueled by the COVID-19 pandemic. Recent classification systems acknowledge that impairing health-related worries and beliefs can emerge in early childhood with significant levels of symptoms persisting throughout childhood, and possibly continuous with diagnostic considerations in adulthood. This narrative review summarizes recent research advances in health anxiety in children and adolescents, focusing on various developmental aspects of health anxiety and related concepts in youths. Findings suggest that health anxiety symptoms in young age groups are associated with impairment, distress, and increased healthcare use, as well as substantial comorbidity with mainly other emotional problems and disorders. Furthermore, longitudinal studies suggest that childhood health anxiety can persist across adolescence, perhaps with links to chronic courses in adulthood. The growing literature was further reviewed, thus extending our understanding of early risk factors, including the potential role of exposure to serious illness and transgenerational transmission of health anxiety. Learning more about developmental trajectories will be highly relevant to inform strategies for early detection and prevention. While modified cognitive behavioral therapies in adults are successful in treating health anxiety, specific interventions have not yet been tested in youths. Given substantial overlaps with other psychopathology, it could be important to develop and explore more transdiagnostic and scalable approaches that take advantage of common factors in psychotherapy, while also including a wider perspective on potential familiar maladaptive illness cognitions and behaviors.

Symptom Profile Characterization Using the Beck Anxiety Inventory Among Undergraduates in the United States

BACKGROUND

The Beck Anxiety Inventory (BAI) is widely used to measure the severity of anxiety. This tool may additionally allow for an in-depth analysis of symptom typology, as reported symptoms can be placed into four categories (subjective, neurophysiologic, autonomic, and panic-related). Although overall severity ratings in populations may be similar, the type of symptoms reported as severe may differ dependent on characteristics of the populations assessed.

AIMS

This study examines the variety of anxiety symptoms manifested among U.S. university students and the impact of symptom typology on seeking treatment.

METHOD

This was an online survey completed by undergraduate students in the United States, responding to questions including the BAI.

RESULTS

A multivariate logistic regression analysis model showed that the likelihood of students seeking treatment increased when they experienced more "subjective" anxiety symptoms, odds ratio (OR) = 2.443, 95% confidence interval (CI) = [1.462, 4.082], p = .001, as compared to symptoms in the other three categories. Students were also asked to report which symptoms were "most bothersome" to them. Many students reported difficulty sleeping and an inability to concentrate. These symptoms are not measured by the BAI.

CONCLUSION

The results of this study show the potential for the BAI to be used as a symptom categorization tool to be considered independently in identifying target areas for treatment. An understanding of the existence of these gaps may allow providers to better identify students with anxiety who present with symptoms not included in the BAI.

Internet-Based Cognitive-Behavioral Therapy for Individuals Experiencing Panic Attacks: A Scoping Literature Review

Panic attacks (PAs) are prevalent and highly comorbid with various physical and psychological disorders. Cognitive-behavioral therapy (CBT) is a well-established psychosocial intervention. Internet-delivered CBT (ICBT) presents a promising avenue to overcome barriers and provide evidence-based support to those in need. The current scoping review aimed to systematically map the existing literature and identify knowledge gaps regarding the impact of ICBT on outcome measures for individuals experiencing PAs. The PRISMA guidelines for scoping reviews were used. A total of 3,044 records were retrieved, and 18 studies from 2013 to 2023 were ultimately included in the analysis. ICBT demonstrated effectiveness as a psychosocial intervention for improving panic symptoms and anxiety in individuals with PAs. However, the impact of ICBT on quality of life (QOL) remains inconclusive. All studies included in this review focused on assessing the severity of panic symptoms, with limited emphasis on measuring QOL. This scoping review holds significant implications for research and practice. However, further addressing the research needs identified in this review will enhance our understanding and improve treatment outcomes for PAs.

When is the best time to screen for perinatal anxiety? A longitudinal cohort study

BACKGROUND

For screening for anxiety during pregnancy and after birth to be efficient and effective it is important to know the optimal time to screen in order to identify women who might benefit from treatment.

AIMS

To determine the optimal time to screen for perinatal anxiety to identify women with anxiety disorders and those who want treatment. A secondary aim was to examine the stability and course of perinatal anxiety over time.

METHODS

Prospective longitudinal cohort study of 2243 women who completed five screening questionnaires of anxiety and mental health symptoms in early pregnancy (11 weeks), mid-pregnancy (23 weeks), late pregnancy (32 weeks) and postnatally (8 weeks). Anxiety and mental health questionnaires were the GAD7, GAD2, SAAS, CORE-10 and Whooley questions. To establish presence of anxiety disorders diagnostic interviews were conducted with a subsample of 403 participants.

RESULTS

Early pregnancy was the optimal time to screen for anxiety to identify women with anxiety disorders and women wanting treatment at any time during pregnancy or postnatally. These findings were consistent across all five questionnaires of anxiety and mental health. Receiving treatment for perinatal mental health problems was most strongly associated with late pregnancy and/or postnatal assessments. Anxiety symptoms were highest in early pregnancy and decreased over time.

CONCLUSION

Findings show that screening in early pregnancy is optimal for identifying women who have, or develop, anxiety disorders and who want treatment. This has clear implications for practice and policy for anxiety screening during the perinatal period.

Developing and Implementing a Web-Based Branching Logic Survey to Support Psychiatric Crisis Evaluations of Individuals With Developmental Disabilities: Qualitative Study and Evaluation of Validity

BACKGROUND

Individuals with developmental disabilities (DD) experience increased rates of emotional and behavioral crises that necessitate assessment and intervention. Psychiatric disorders can contribute to crises; however, screening measures developed for the general population are inadequate for those with DD. Medical conditions can exacerbate crises and merit evaluation. Screening tools using checklist formats, even when designed for DD, are too limited in depth and scope for crisis assessments. The Sources of Distress survey implements a web-based branching logic format to screen for common psychiatric and medical conditions experienced by individuals with DD by querying caregiver knowledge and observations.

OBJECTIVE

This paper aims to (1) describe the initial survey development, (2) report on focus group and expert review processes and findings, and (3) present results from the survey's clinical implementation and evaluation of validity.

METHODS

Sources of Distress was reviewed by focus groups and clinical experts; this feedback informed survey revisions. The survey was subsequently implemented in clinical settings to augment providers' psychiatric and medical history taking. Informal and formal consults followed the completion of Sources of Distress for a subset of individuals. A records review was performed to identify working diagnoses established during these consults.

RESULTS

Focus group members (n=17) expressed positive feedback overall about the survey's content and provided specific recommendations to add categories and items. The survey was completed for 231 individuals with DD in the clinical setting (n=161, 69.7% men and boys; mean age 17.7, SD 10.3; range 2-65 years). Consults were performed for 149 individuals (n=102, 68.5% men and boys; mean age 18.9, SD 10.9 years), generating working diagnoses to compare survey screening results. Sources of Distress accuracy rates were 91% (95% CI 85%-95%) for posttraumatic stress disorder, 87% (95% CI 81%-92%) for anxiety, 87% (95% CI 81%-92%) for episodic expansive mood and bipolar disorder, 82% (95% CI 75%-87%) for psychotic disorder, 79% (95% CI 71%-85%) for unipolar depression, and 76% (95% CI 69%-82%) for attention-deficit/hyperactivity disorder. While no specific survey items or screening algorithm existed for unspecified mood disorder and disruptive mood dysregulation disorder, these conditions were caregiver-reported and working diagnoses for 11.7% (27/231) and 16.8% (25/149) of individuals, respectively.

CONCLUSIONS

Caregivers described Sources of Distress as an acceptable tool for sharing their knowledge and insights about individuals with DD who present in crisis. As a screening tool, this survey demonstrates good accuracy. However, better differentiation among mood disorders is needed, including the addition of items and screening algorithm for unspecified mood disorder and disruptive mood dysregulation disorder. Additional validation efforts are necessary to include a more geographically diverse population and reevaluate mood disorder differentiation. Future study is merited to investigate the survey's impact on the psychiatric and medical management of distress in individuals with DD.

Temporal network of experience sampling methodology identifies sleep disturbance as a central symptom in generalized anxiety disorder

BACKGROUND

A temporal network of generalized anxiety disorder (GAD) symptoms could provide valuable understanding of the occurrence and maintenance of GAD. We aim to obtain an exploratory conceptualization of temporal GAD network and identify the central symptom.

METHODS

A sample of participants (n = 115) with elevated GAD-7 scores (Generalized Anxiety Disorder 7-Item Questionnaire [GAD-7] ≥ 10) participated in an online daily diary study in which they reported their GAD symptoms based on DSM-5 diagnostic criteria (eight symptoms in total) for 50 consecutive days. We used a multilevel VAR model to obtain the temporal network.

RESULTS

In temporal network, a lot of lagged relationships exist among GAD symptoms and these lagged relationships are all positive. All symptoms have autocorrelations and there are also some interesting feedback loops in temporal network. Sleep disturbance has the highest Out-strength centrality.

CONCLUSIONS

This study indicates how GAD symptoms interact with each other and strengthen themselves over time, and particularly highlights the relationships between sleep disturbance and other GAD symptoms. Sleep disturbance may play an important role in the dynamic development and maintenance process of GAD. The present study may develop the knowledge of the theoretical model, diagnosis, prevention and intervention of GAD from a temporal symptoms network perspective.

Prevalence and comorbidity of anxiety disorder in school-attending children and adolescents aged 6-16 years in China

BACKGROUND

The reported prevalence rate of anxiety disorder in the paediatric population varies widely between different counties. Currently, there is no national epidemiological survey of childhood anxiety disorder in China. This study aims to investigate the national prevalence of anxiety disorder, the distribution profiles of different subtypes and its comorbidity rates among school students.

METHODS

A nationwide epidemiological survey of mental disorders in school students aged 6-16 years was conducted. Participants were randomly recruited from five provinces in China. The Child Behavior Checklist was used to screen students at high risk for mental disorders. The final diagnosis was made based on the Diagnostic and Statistical Manual-IV. The point prevalence and comorbidity rate of anxiety disorder were calculated, and the difference between age, sex and socioeconomic status groups was also compared.

RESULTS

Generalised anxiety disorder (GAD) was the most common anxiety disorder in school-attending children and adolescents, with a prevalence rate of 1.3% (95% CI: 1.2 to 1.3). Separation anxiety and specific phobia were more common in children than in adolescents. Girls had a higher prevalence of panic disorder (0.3% vs 0.2%, χ2=14.6, p<0.001) and agoraphobia (0.9% vs 0.8%, χ2=4.3, p=0.03) than that of boys. We found no significant difference between developed and less developed areas. Girls were more likely to have panic disorder and GAD than boys, with ratios of 2.13:1 and 1.01:1, respectively. The co-occurrence of anxiety disorder and attention-deficit and disruptive behaviour disorder was very common, ranging from 40% to 85%.

CONCLUSIONS

Anxiety disorder was prevalent among school students in China, and comorbidity with attention-deficit and disruptive disorder was very common. The data imply that screening for anxiety disorder is needed in school settings. Policies should be adapted to provide psychological services to children and adolescents. A comprehensive assessment is recommended in clinical practice.

Reliability and validity of the Patient Health Questionnaire-4 scale and its subscales of depression and anxiety among US adults based on nativity

BACKGROUND

The burdens of anxiety and depression symptoms have significantly increased in the general US population, especially during this COVID-19 epidemiological crisis. The first step in an effective treatment for anxiety and depression disorders is screening. The Patient Health Questionnaire-4 (PHQ-4, a 4-item measure of anxiety/depression) and its subscales (PHQ-2 [a 2-item measure of depression] and Generalized Anxiety Disorder [GAD-2, a 2-item measure of anxiety]) are brief but effective mass screening instruments for anxiety and depression symptoms in general populations. However, little to no study examined the psychometric properties (i.e., reliability and validity) of the PHQ-4 and its subscales (PHQ-2 and GAD-2) in the general US adult population or based on US nativity (i.e., foreign-born vs. the US-born). We evaluated the psychometric properties of the PHQ-4 and its subscales in US adults, as well as the psychometric equivalence of the PHQ-4 scale based on nativity.

METHODS

We conducted a cross-sectional survey of 5,140 adults aged ≥ 18 years. We examined the factorial validity and dimensionality of the PHQ-4 with confirmatory factor analysis (CFA). A multiple-group confirmatory factor analysis (MCFA) was used to evaluate the comparability of the PHQ-4 across nativity groups. Reliability indices were assessed. Also, the scales' construct validities were assessed by examining the associations of both the PHQ-4 and its subscales' scores with the sociodemographic characteristics and the 3-item UCLA Loneliness scale.

RESULTS

The internal consistencies were high for the PHQ-4 scale (α = 0.92) and its subscales of PHQ-2 (α = 0.86) and GAD-2 (α = 0.90). The CFA fit indices showed evidence for the two-factor structure of the PHQ-4. The two factors (i.e., anxiety and depression) were significantly correlated (r = 0.92). The MCFA demonstrated measurement invariance of the PHQ-4 across the nativity groups, but the model fits the data better in the foreign-born group. There were significant associations of the PHQ-4 scale and its subscales' scores with the sociodemographic characteristics and the UCLA Loneliness scale (all p < 0.001).

CONCLUSIONS

The PHQ-4 and its subscales are reliable and valid measures to screen anxiety and depression symptoms in the general US adult population, especially in foreign-born individuals during the COVID-19 pandemic.

Associations between anxiety, depression, and personal mastery in community-dwelling older adults: a network-based analysis

BACKGROUND

In China, about 18.70% of the population aged 60 years and older are at risk of low personal mastery as well as anxiety and depression for a variety of reasons. The purpose of this study was to construct a symptom network model of the relationship between anxiety, depression, and personal mastery in community-dwelling older adults and to identify central and bridge symptoms in this network.

METHODS

Depression, anxiety, and personal mastery were measured using the Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder Scale (GAD-7), and Personal Mastery Scale (PMS), respectively. A total of 501 older adults in 16 communities in Changzhou and Zhenjiang, Jiangsu Province, China, were surveyed by using a combination of stratified sampling and convenience sampling methods. The R language was used to construct the network.

RESULTS

(1) The network structure of anxiety-depression-personal mastery was stable, with "Nervousness" (node GAD1, strength = 1.38), "Sad mood" (node PHQ2, strength = 1.22), " Inability to change" (node PMS2, strength = 1.01) and "Involuntarily" (node PMS3, strength = 0.95) as the central symptoms. (2) "Irritability" (node GAD6, bridge strength = 0.743), "Sad mood" (node PHQ2, bridge strength = 0.655), and "Trouble relaxing" (node GAD4, bridge strength = 0.550) were the bridge symptoms connecting anxiety, depressive symptoms, and personal mastery. (3) In the network comparison test (NCT), residence, somatic chronic comorbidity and gender had no significant effect on network structure.

CONCLUSIONS

The construction of the anxiety-depression-personal mastery network structure opens up new possibilities for mechanisms of action and intervention formulation for psychological disorders in community-dwelling older adults. The identification of central symptoms (e.g., nervousness, sad mood, inability to change, involuntarily) and bridge symptoms (e.g., irritability, sad mood, trouble relaxing) in community-dwelling older adults with anxiety, depression, and low sense of mastery can provide a scientific basis for the development of precise interventions.

The effect of video informing adolescents having Polymerase Chain Reaction (rRT-PCR) test on anxiety during the Coronavirüs (COVID-19) pandemic: A randomized controlled study

AIM

This study aimed to determine if video information on Polymerase Chain Reaction (rRT-PCR) testing reduces anxiety in adolescents.

DESIGN AND METHODS

A randomized controlled experimental study with a parallel-group design was conducted. The sample size was determined by G*Power analysis, and 136 adolescents were included in each group accordingly. The data were collected using the Child/Parent Information Form, State and Trait Anxiety Inventory, and Coronavirus Anxiety Scale. Chi-square, Independent Sample t-test, and Paired Sample t-test were used to analyze the data.

RESULTS

It was determined that adolescents experienced moderate anxiety before the procedure. It was found that the majority of adolescents did not have a COVID-19 positive patient in their relatives (83.1%) or in the same house (82.7%). It was determined that they had COVID-19 positive friends at school (56.2%) but not in class (61.4%) and had no contact with positive friends (69.1%). While the post-operative state anxiety level of the adolescents informed by video was 38.76 ± 10.77, the anxiety level of the adolescents in the control group was 41.68 ± 11.92. Informing with video significantly decreased the anxiety level of adolescents (p = 0.035).

CONCLUSION

Video information reduces state anxiety after the procedure.

PRACTICE IMPLICATIONS

It is recommended that video information before rRT-PCR test should be implemented in all hospitals, tablets, televisions, or phones should be used to provide information against the risk of contamination, and other studies should be conducted to show the effectiveness of video information.

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 (β = -0.22; 95% CI [-0.38, -0.07]; R2 = 0.07, p = .005) and depression symptoms (β = -0.25; 95% CI [-0.42, -0.07]; R2 = 0.05, p = .006). Similarly, timed-stands test scores were associated with anxiety (β = -0.33; 95% CI [-0.54, -0.13]; R2 = 0.09, p = .002) and depression (β = -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.

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.

Bereavement and Loss: Understanding Grief in Older People

Everyone experiences grief from time to time, but older people are more likely to experience grief simply because they live longer. Grief, bereavement, and mourning are different elements associated with death of a loved one. For most people, grief follows a fairly predictable trajectory, and over time resolves. One of the most used descriptions of grief was developed by Elizabeth Kubler-Ross and it is reviewed herein. However, for some people, grief becomes unbearable and chronic leading to prolonged grief disorder. For clinicians, it's essential to differentiate between prolonged grief disorder and major depressive disorder. Older people who experience unbearable grief often need medication to deal with some of its symptoms, which include depression, anxiety, hypertension, and lack of sleep. Older people also need considerable support as they deal with grief so that they do not become isolated, experience comorbidities, or spiral into physical and mental decline. Little specific research has examined pharmacists' opportunities to help older people who have prolonged grief, but some data suggest that these patients are more likely to visit the pharmacy and need medication more than others.

[VR-supported therapy for anxiety and posttraumatic stress disorder: current possibilities and limitations]

BACKGROUND

Virtual reality (VR) is increasingly used in psychotherapy, and the speed of development of therapeutic VR tools is continuously increasing.

OBJECTIVE

This narrative review provides an overview of the state of the art regarding VR applications for psychotherapy.

MATERIAL AND METHODS

The current state of VR therapy research for anxiety disorders and posttraumatic stress disorder (PTSD) is summarized. The focus lies on VR exposure therapy. Current developments in the field are outlined.

RESULTS

For anxiety disorders, especially phobic disorders, there are already positive recommendations in the current German S3 guidelines. For PTSD, the development of VR therapy tools is still in a relatively early stage.

CONCLUSION

The development of mobile cost-effective VR solutions in recent years has enabled entirely new applications for VR. The empirical challenges of these new developments are considerable. Nevertheless, the chances for an improvement of psychotherapeutic routine care are good.

Psychometric properties of the Distress Tolerance Scale in a clinical sample

The factor structure, reliability, and concurrent validity of the Distress Tolerance Scale were evaluated in a large outpatient sample (N = 775). Prior research demonstrates mixed findings regarding the most appropriate factor structure, finding evidence for the presence of four subfactors as well as a potential second-order (hierarchical) General Distress Tolerance factor. Competing factor structures were compared using confirmatory factor analyses. A second-order hierarchical model with correlated residuals fit the data well, though results suggested poor factor discrimination. A bifactor hierarchical model also demonstrated acceptable fit. However, all subfactors except for Regulation demonstrated small or nonsignificant loadings and/or variances. The model was respecified with all items loading onto a General Distress Tolerance factor and three items loading onto the Regulation factor, which also demonstrated acceptable fit. In support of its concurrent validity, General Distress Tolerance was more strongly associated with neuroticism and a measure of difficulties with emotion regulation than with symptoms of anxiety and depression. The present study extends the literature by demonstrating support for a hierarchical bifactor structure and the favorable psychometric properties of the Distress Tolerance Scale in a large clinical sample.

Which client with generalized anxiety disorder benefits from a mindfulness ecological momentary intervention versus a self-monitoring app? Developing a multivariable machine learning predictive model

Precision medicine methods (machine learning; ML) can identify which clients with generalized anxiety disorder (GAD) benefit from mindfulness ecological momentary intervention (MEMI) vs. self-monitoring app (SM). We used randomized controlled trial data of MEMI vs. SM for GAD (N = 110) and tested three ML models to predict one-month follow-up reliable improvement in GAD severity, perseverative cognitions (PC), trait mindfulness (TM), and executive function (EF). Eleven baseline predictors were tested regarding differential reliable change from MEMI vs. SM (age, sex, race, EF errors, inhibitory dyscontrol, set-shifting deficits, verbal fluency, working memory, GAD severity, TM, PC). The final top five prescriptive predictor models of all outcomes performed well (AUC = .752 .886). The following variables predicted better outcome from MEMI vs. SM: Higher GAD severity predicted more GAD improvement but less EF improvement. Elevated PC, inhibitory dyscontrol, and verbal dysfluency predicted better improvement in most outcomes. Greater set-shifting and TM predicted stronger improvements in GAD symptoms and TM. Older age predicted more alleviation of GAD and PC symptoms. Women exhibited more enhancements in trait mindfulness and EF than men. White individuals benefitted more than non-White. PC, TM, EF, and sociodemographic data might help predictive models optimize intervention selection for GAD.

The evidence-based COPE program: Reducing the time between diagnosing and treating depression and anxiety in youth

ABSTRACT

The soaring prevalence of depression and anxiety in children, teenagers, and young adults is now a public health epidemic, yet access to timely evidence-based mental health treatment is often lacking due to a severe shortage of mental health providers. This article provides an overview of the current state of depression and anxiety in children and adolescents as well as first-line evidence-based treatment. The Creating Opportunities for Personal Empowerment (COPE) program, a cognitive-behavioral skills-building intervention, is highlighted as an evidence-based intervention for timely treatment that can be delivered by NPs, physicians, and physician associates/assistants in primary care settings, school-based health centers, and chronic care clinics with reimbursement as well as in schools and universities as a preventive mental health intervention.

Evaluation of subclinical cardiovascular risk in drug-naive pediatric patients with anxiety disorders

OBJECTIVE

This study examined subclinical atherosclerosis in drug-naïve children with anxiety disorders using non-invasive measures to investigate the clinical features associated with subclinical atherosclerosis.

METHOD

A total of 37 drug-naive children and adolescents with anxiety disorders and 37 healthy controls were included in the study. The Children's Depression Inventory (CDI) and the State-Trait Anxiety Inventory (STAI-T and STAI-S) were used to assess children's depression and anxiety levels. Carotid artery intima-media (cIMT), epicardial adipose tissue (EAT), and periaortic adipose tissue (PAT) thicknesses, which are indicators of subclinical atherosclerosis, were obtained by echocardiographic measurements.

RESULTS

Multivariate analysis of covariance (MANCOVA) revealed a significant main effect on cIMT, EAT thickness, and PAT thickness, independent of confounding factors such as age, sex, body mass index, mean blood pressure, and family income (Pillai's Trace V = .76, F (1, 72) = 35.60, P < .001, ηp2 = .76). Analysis of covariance (ANCOVA) showed that cIMT, EAT thickness, and PAT thickness values were significantly higher in the anxiety disorder group compared to the the control group (P < .001). In partial correlation analysis, a positive correlation was observed between STAI-T and cIMT and EAT thickness. In linear regression analyses, age and STAI-T were significantly correlated with cIMT and EAT thickness levels.

CONCLUSIONS

These results suggest that subclinical cardiovascular risk is significantly increased in children and adolescents with anxiety disorders.

The Worry Behaviors Inventory-Perinatal Revised: Adaptation and Initial Validation for Use in Perinatal Samples

Generalized anxiety disorder (GAD) is a leading mental health concern during pregnancy and the postpartum (perinatal) period. People with GAD engage in problematic behaviors to manage their distress. However, the extent of GAD behaviors during the perinatal period may not be adequately captured by the Worry Behaviors Inventory (WBI), the most comprehensive measure of GAD behaviors to date. We evaluated the structure of the initial WBI item-pool and then evaluated the internal consistency, construct validity, and predictive utility of the Perinatal Revised WBI (WBI-PR) in a sample of 214 perinatal women with and without GAD. A two-factor, 10-item scale was supported, and some of the retained items differed from the original WBI. Internal consistency of the WBI-PR was acceptable, and evidence of construct validity was demonstrated. The WBI-PR predicted GAD diagnostic status both alone and beyond existing generalized anxiety and depression symptoms. Implications of these findings are discussed.

Construction of machine learning models for recognizing comorbid anxiety in epilepsy patients based on their clinical and quantitative EEG features

BACKGROUND

This study aimed to construct prediction models for the recognizing of anxiety disorders (AD) in patients with epilepsy (PWEs) by combining clinical features with quantitative electroencephalogram (qEEG) features and using machine learning (ML).

METHODS

Nineteen clinical features and 20-min resting-state EEG were collected from 71 PWEs comorbid with AD and another 60 PWEs without AD who met the inclusion-exclusion criteria of this study. The EEG were preprocessed and 684 Phase Locking Value (PLV) and 76 Lempel-Ziv Complexity (LZC) features on four bands were extracted. The Fisher score method was used to rank all the derived features. We constructed four models for recognizing AD in PWEs, whether PWEs based on different combinations of features using eXtreme gradient boosting (XGboost) and evaluated these models using the five-fold cross-validation method.

RESULTS

The prediction model constructed by combining the clinical, PLV, and LZC features showed the best performance, with an accuracy of 96.18%, precision of 94.29%, sensitivity of 98.33%, F1-score of 96.06%, and Area Under the Curve (AUC) of 0.96. The Fisher score ranking results displayed that the top ten features were depression, educational attainment, α_P3LZC, α_T6-PzPLV, α_F7LZC, β_Fp2-O1PLV, θ_T4-CzPLV, θ_F7-PzPLV, α_Fp2LZC, and θ_T4-PzPLV.

CONCLUSIONS

The model, constructed by combining the clinical and qEEG features PLV and LZC, efficiently identified the presence of AD comorbidity in PWEs and might have the potential to complement the clinical diagnosis. Our findings suggest that LZC features in the α band and PLV features in Fp2-O1 may be potential biomarkers for diagnosing AD in PWEs.

Positive reappraisal coping mediates the relationship between parental abuse and lack of affection on adulthood generalized anxiety severity

Exposure to parental abuse and lack of parental affection during childhood are risk factors for adulthood psychopathology. Tendency to engage in positive reappraisal may be a plausible mechanism underlying this relationship. The current study examined if positive reappraisal coping mediated the relationship between maternal/paternal abuse/affection and adulthood generalized anxiety disorder (GAD) symptoms. Participant data (N = 3294) from the Midlife Development in the United States study was collected in three waves, spaced nine years apart. Longitudinal structural equation mediation modeling examined whether positive reappraisal coping at Time 2 mediated the relationship between maternal/paternal abuse/affection at Time 1 and GAD symptoms at Time 3, controlling for GAD symptoms at Time 1. Positive reappraisal coping mediated maternal/paternal childhood abuse - GAD symptom severity and maternal/paternal childhood affection - GAD severity relations. Maternal and paternal abuse was associated with lower positive reappraisal tendencies, predicting increased GAD symptom severity. Conversely, higher maternal/paternal affection was associated with increased positive reappraisal, predicting lower GAD severity. Incremental prediction revealed that childhood abuse to GAD severity via positive reappraisal path was significant for maternal but not paternal abuse, whereas affection from both parents remained significant. Positive reappraisal coping may be a possible mechanism linking childhood experiences to adulthood GAD severity.

Anxiety and Disruptive Behavior Symptoms and Disorders in Preschool-Age Offspring of Parents With and Without Bipolar Disorder: Associations With Parental Comorbidity

OBJECTIVE

We examined the relative contribution of parental bipolar disorder (BPD) and psychiatric comorbidities (disruptive behavior disorders [DBD] and anxiety disorders) in predicting psychiatric symptoms and disorders in 2-5-year-old offspring.

METHODS

Participants were 60 families with a parent with BPD and 78 offspring and 70 comparison families in which neither parent had a mood disorder and 91 offspring. Parent and offspring diagnoses and symptoms were assessed using standardized diagnostic interviews and measures, with offspring assessors masked to parental diagnoses.

RESULTS

Offspring of parents with BPD had significant elevations in behavioral, mood and anxiety disorders and symptoms. Both parental BPD and DBD contributed to elevations in child disruptive behavioral symptoms, whereas child anxiety symptoms were more strongly predicted by comorbid parental anxiety. Parental BPD was a stronger predictor than comorbid DBD of child DBDs.

CONCLUSION

Some of the elevated risk for disorders in preschoolers is accounted for by parental comorbidity.

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.

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.

Psychodynamic Psychiatry and the Care of Persons with Vision Loss and Blindness

The authors describe the clinical relevance of the psychiatric concept of bidirectionality when caring for persons with comorbid disorders, and they propose a psychodynamic framework to guide the treatment of persons with vision loss and blindness. Since persons with vision loss have an increased risk of depressive and anxiety disorders, they recommend targeted screening, integrated services, and a biopsychosocial approach to clinical care. The psychoanalytic concept of aphanisis, first described by Ernest Jones and later developed by Lacan and Kohut, is briefly discussed. Common psychotherapy themes in the treatment of persons who experience vision loss from systemic illness include reactivation of memories of past traumas resulting in avoidance, social withdrawal, depressive states, catastrophic thinking, a sense of foreshortened future, anhedonia, and fear of disintegration and invisibility. Psychotherapy also serves to correct negative introjects from ableist societal attitudes.

Screening, Assessment, and Treatment of Perinatal Mental Health in Obstetrical Settings

Perinatal mood and anxiety disorders (PMADs) are common, yet obstetricians receive little training prior to independent practice on screening, assessing, diagnosing, and treating patients with depression and anxiety. Untreated PMADs lead to adverse pregnancy and fetal outcomes. Obstetricians are in a unique position to address PMADs. The following serves as a resource for addressing PMADs in obstetric practice.

Psychometric Properties of the Short Scale Anxiety Sensitivity Index Among Adults with Chronic Respiratory Disease

Approximately one-third of adults with chronic respiratory disease (CRD) have comorbid depressive and anxiety disorders; yet these disorders are often unrecognized in this patient population. Transdiagnostic processes such as anxiety sensitivity (AS) are useful for identifying mechanisms underlying psychological and heath conditions. The Short-Scale AS Index (SSASI) is a brief self-report measure of AS which has potential clinical utility among CRD populations to evaluate psychological distress and inform comprehensive care. The present study investigated the psychometric properties of the SSASI among adults with CRDs. Participants were recruited from a web-based panel of adults with CRDs (n = 768; 49.3% female; 57.8% White) including adults with asthma only (n = 230), COPD only (n = 321), or co-occurring asthma and COPD (n = 217). Participants completed a battery of self-report questionnaires assessing psychological and medical symptoms. Analyses were conducted to examine the factor structure and measurement invariance across CRD groups. Convergent validity and criterion validity of the SSASI were assessed within each group. Results supported partial measurement invariance across CRD groups. The SSASI demonstrated high reliability, convergent validity, and criterion validity with each CRD group. Findings from this study and existing work indicate that the SSASI is an effective and economical assessment tool for identifying patients CRD who may benefit from psychological interventions to reduce AS.

The genetic architecture of youth anxiety: a study protocol

BACKGROUND

Anxiety disorders are the most common psychiatric problems among Canadian youth and typically have an onset in childhood or adolescence. They are characterized by high rates of relapse and chronicity, often resulting in substantial impairment across the lifespan. Genetic factors play an important role in the vulnerability toward anxiety disorders. However, genetic contribution to anxiety in youth is not well understood and can change across developmental stages. Large-scale genetic studies of youth are needed with detailed assessments of symptoms of anxiety disorders and their major comorbidities to inform early intervention or preventative strategies and suggest novel targets for therapeutics and personalization of care.

METHODS

The Genetic Architecture of Youth Anxiety (GAYA) study is a Pan-Canadian effort of clinical and genetic experts with specific recruitment sites in Calgary, Halifax, Hamilton, Toronto, and Vancouver. Youth aged 10-19 (n = 13,000) will be recruited from both clinical and community settings and will provide saliva samples, complete online questionnaires on demographics, symptoms of mental health concerns, and behavioural inhibition, and complete neurocognitive tasks. A subset of youth will be offered access to a self-managed Internet-based cognitive behavioral therapy resource. Analyses will focus on the identification of novel genetic risk loci for anxiety disorders in youth and assess how much of the genetic risk for anxiety disorders is unique or shared across the life span.

DISCUSSION

Results will substantially inform early intervention or preventative strategies and suggest novel targets for therapeutics and personalization of care. Given that the GAYA study will be the biggest genomic study of anxiety disorders in youth in Canada, this project will further foster collaborations nationally and across the world.

Action recommendations review in community-based therapy and depression and anxiety outcomes: a machine learning approach

BACKGROUND

While the positive impact of homework completion on symptom alleviation is well-established, the pivotal role of therapists in reviewing these assignments has been under-investigated. This study examined therapists' practice of assigning and reviewing action recommendations in therapy sessions, and how it correlates with patients' depression and anxiety outcomes.

METHODS

We analyzed 2,444 therapy sessions from community-based behavioral health programs. Machine learning models and natural language processing techniques were deployed to discern action recommendations and their subsequent reviews. The extent of the review was quantified by measuring the proportion of session dialogues reviewing action recommendations, a metric we refer to as "review percentage". Using Generalized Estimating Equations modeling, we evaluated the correlation between this metric and changes in clients' depression and anxiety scores.

RESULTS

Our models achieved 76% precision in capturing action recommendations and 71.1% in reviewing them. Using these models, we found that therapists typically provided clients with one to eight action recommendations per session to engage in outside therapy. However, only half of the sessions included a review of previously assigned action recommendations. We identified a significant interaction between the initial depression score and the review percentage (p = 0.045). When adjusting for this relationship, the review percentage was positively and significantly associated with a reduction in depression score (p = 0.032). This suggests that more frequent review of action recommendations in therapy relates to greater improvement in depression symptoms. Further analyses highlighted this association for mild depression (p = 0.024), but not for anxiety or moderate to severe depression.

CONCLUSIONS

An observed positive association exists between therapists' review of previous sessions' action recommendations and improved treatment outcomes among clients with mild depression, highlighting the possible advantages of consistently revisiting therapeutic homework in real-world therapy settings. Results underscore the importance of developing effective strategies to help therapists maintain continuity between therapy sessions, potentially enhancing the impact of therapy.

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.

Measurement invariance and differential item functioning of the PHQ-9 and GAD-7 between working age and older adults seeking treatment for common mental disorders

BACKGROUND

The nine-item Patient Health Questionnaire (PHQ-9) and seven-item Generalised Anxiety Disorder (GAD-7) scale are widely used clinically and within research, and so it is important to determine how the measures, and individual items within the measures, are answered by adults of differing ages. This study sought to evaluate measurement invariance and differential item functioning (DIF) of the PHQ-9 and GAD-7 between working age and older adults seeking routine psychological treatment.

METHODS

Data of working age (18-64 years old) and older (≥65) adults in eight Improving Access to Psychological Therapies (IAPT) services were used. Confirmatory factor analysis (CFA) was used to establish unidimensionality of the PHQ-9 and GAD-7, with multiple-group CFA to test measurement invariance and The Multiple Indicators, Multiple Causes Models approach to assess DIF. The employed methods were applied to a propensity score matched (PSM) sample in sensitivity analyses to control for potential confounding.

RESULTS

Data from 166,816 patients (159,325 working age, 7491 older) were used to show measurement invariance for the PHQ-9 and GAD-7, with limited evidence of DIF and similar results found with a PSM sample (n = 5868).

LIMITATIONS

The localised sample creates an inability to detect geographical variance, and the potential effect of unmeasured confounders cannot be ruled out.

CONCLUSIONS

The findings support the use of the PHQ-9 and GAD-7 measures for working age and older adults, both clinically and in research settings. This study validates using the measures for these age groups to assess clinically significant symptom thresholds, and monitor treatment outcomes between them.

Study protocol for a randomized controlled trial testing the efficacy of Emotion Detectives In-Out: a blended version of the unified protocol for transdiagnostic treatment of emotional disorders in Portuguese children

BACKGROUND

Childhood emotional disorders (EDs; i.e., anxiety and depressive disorders) are currently a public health concern. Their high prevalence, long-term effects, and profound influence on the lives of children and families highlight the need to identify and treat these disorders as early and effectively as possible. This clinical trial will examine the efficacy of a blended version (i.e., combining face-to-face and online sessions into one treatment protocol) of the Unified Protocol for Children (the "Emotion Detectives In-Out" program). This program is a manualized cognitive-behavioral therapy for the transdiagnostic treatment of EDs in children aged 7 to 12 years that aims to reduce the intensity and frequency of strong and aversive emotional experiences by helping children learn how to confront those emotions and respond to them in more adaptive ways.

METHODS

This study is designed as a multicenter equivalence randomized controlled parallel-group two-arm trial comparing the Emotion Detectives In-Out program with an evidenced-based group intervention for children with anxiety disorders (the Coping Cat program). Participants will be children aged between 7 and 12 years with an anxiety disorder or with clinically significant anxiety symptoms as well as one of their parents or a legal representative. A minimum sample size of 138 children (69 per group) is needed to test whether the efficacy of the proposed intervention is equivalent to that of the well-established Coping Cat intervention.

DISCUSSION

We expect Emotion Detectives In-Out to be a feasible and efficacious alternative intervention for treating children's EDs by allowing for a greater increase in children's access to care. A blended format is expected to overcome common barriers to treatment (e.g., parents´ lack of time to attend regular sessions) and make the intervention more accessible to families.

TRIAL REGISTRATION

The clinical trial is registered at ClinicalTrials.gov (Identifier: NCT05747131, date assigned February 28, 2023).

[Anxiety]

In this article, we will address 10 questions about anxiety that are relevant to doctors who encounter this in their practice. This often occurs in the primary care setting, where individuals with anxiety frequently present with somatic complaints. A focused medical history, including questions about the use and withdrawal of psychoactive substances, can assist in the diagnostic process. Psychoeducation may be sufficient, otherwise cognitive-behavioral therapy can be conducted. In cases of non-response, serotonergic antidepressants represent a treatment option. Half of the individuals with anxiety symptoms experience remission, while the other half have a recurrent or chronic course, which may be accompanied by comorbid depression.

The caffeine dilemma: unraveling the intricate relationship between caffeine use disorder, caffeine withdrawal symptoms and mental well-being in adults

OBJECTIVE

This study aimed to explore the relationship between caffeine use disorder (CUD), caffeine withdrawal symptoms and the prevalence of depression, anxiety and stress (DASS) in adults.

DESIGN

The study utilised a cross-sectional design to assess the relationships between CUD, caffeine withdrawal symptoms and DASS.

SETTING

Participants' CUD was evaluated through the Caffeine Use Disorder Questionnaire (CUDQ), while the Depression Anxiety Stress Scale-21 (DASS-21) measured DASS levels. Caffeine withdrawal symptoms and total caffeine intake were calculated based on self-reported consumption of caffeine-rich products.

PARTICIPANTS

The study involved 618 participants with an average age of 27·8 (sd 7·8) years.

RESULTS

Participants consumed an average of 461·21 (sd 11·09) mg/d of caffeine, showing a positive correlation between CUD and total caffeine intake. The risk of CUD increased alongside levels of DASS. Individuals with caffeine withdrawal symptoms had higher CUDQ and DASS scores. A multiple linear regression model revealed significant associations between total caffeine intake (P < 0·001) and DASS-21 score (P < 0·001) with CUDQ score.

CONCLUSIONS

The study concluded that caffeine, while recognised for its potential health benefits, also exhibits properties that may lead to addiction. The development of caffeine use disorder and cessation of caffeine intake can increase DASS levels in adults, indicating the need for awareness and appropriate interventions in public health nutrition.

Effects of sex and gender on the etiologies and presentation of select internalizing psychopathologies

The internalizing spectrum encompasses a subset of psychopathologies characterized by emotional liability, anhedonia, anxiousness, distress, and fear, and includes, among others, diagnoses of major depressive disorder (MDD), generalized anxiety disorder (GAD), and posttraumatic stress disorder (PTSD). In this review, we describe the vast body of work highlighting a role for sex and gender in the environment, symptom onset, genetic liability, and disorder progression and comorbidities of MDD, GAD, and PTSD. We also point the reader to different language used in diverse fields to describe sexual and gender minorities that may complicate the interpretation of emerging literature from the social sciences, psychiatric and psychological sciences, and genetics. Finally, we identify several gaps in knowledge that we hope serve as launch-points for expanding the scope of psychiatric studies beyond binarized sex-stratification. Despite being under-represented in genomics studies, placing emphasis on inclusion of sexual and gender diverse participants in these works will hopefully improve our understanding of disorder etiology using genetics as one tool to inform how biology (e.g., hormone concentration) and environmental variables (e.g., exposure to traumatic events) contribute to differences in symptom onset, pattern, and long-term trajectory.

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.
