DSM-5 illness anxiety disorder and somatic symptom disorder: Comorbidity, correlates, and overlap with DSM-IV hypochondriasis

Challenges to high-quality care in autism with functional somatic symptoms: A case-inspired narrative review and exploratory biopsychosocial model

BackgroundChildren and adolescents with autism spectrum disorder (ASD) frequently experience functional somatic symptoms (FSS), although the underlying causes often remain unclear. Various biological and psychological factors, both individual and within families, such as alexithymia or health anxiety, can intensify these symptoms, sometimes resulting in excessive and unnecessary medical interventions.MethodsA narrative review of the literature was conducted, alongside the presentation of a case report involving a 13-year-old boy with ASD. The case illustrates how personal and familial factors can influence the presentation of FSS and the risks of inappropriate treatment.DiscussionThe findings suggest that psychological and familial factors play a significant role in the manifestation of FSS in ASD. These factors can increase the risk of unnecessary medicalization, as they often lead to misinterpretation of symptoms by caregivers and healthcare providers. The case report further underscores how the interaction of personal and familial dynamics can complicate the management of FSS. A comprehensive biopsychosocial approach that addresses both the individual and the family is crucial for managing FSS in ASD. Future research should focus on developing targeted interventions that address these psychological and familial influences to enhance the quality of care and reduce unnecessary and potentially harmful healthcare utilization in ASD.

General and Health Anxiety in Temporomandibular Disorders: Correlates With Depression, Pain Intensity, Sleep Propensity, Oral Behaviours, Jaw Function, and Oral Health-Related Quality of Life

BACKGROUND

Health anxiety (HA) has been underexplored in temporomandibular disorders (TMDs). This study compared general anxiety (GA) and HA across TMD subtypes, examining correlations with depression, pain intensity, sleep propensity, oral behaviours, jaw function, and oral health-related quality of life (OHRQoL).

METHODS

Participants recruited from TMD patients completed a survey with the General Anxiety Disorder-7 Scale, Whitely Index-8, relevant DC/TMD Axis II measures, Epworth Sleepiness Scale, and Oral Health Impact Profile for TMDs, followed by a physical examination. They were subsequently categorised into Intra-Articular (IT), Pain-Related (PT), and Combined (CT) TMD groups based on DC/TMD algorithms. Data were analysed using the Chi-square Test, non-parametric tests, and logistic regression (α = 0.05).

RESULTS

Among the 371 participants (mean age 29.8 years; 79.5% female), moderate-to-severe GA and depression were found in 15.1%, and high HA was noted in 19.7%. Significant differences were observed across the three TMD subtypes in the proportion of females (CT > PT/IT), age, GA, HA, depression, pain intensity, jaw functional limitation (PT/CT > IT), and OHRQoL (CT ≥ PT > IT). GA was strongly correlated with HA and depression and moderately correlated with OHRQoL, while HA was moderately correlated with both depression and OHRQoL (rs = 0.60-0.77). The multivariate model indicated that CT (OR 2.86), GA (OR 1.35), HA (OR 1.13), pain intensity (OR 1.03), and jaw functional limitation (OR 1.04) significantly increased the odds of low OHRQoL.

CONCLUSIONS

One-fifth of TMD patients exhibited HA, which was moderate to strongly correlated with GA and depression. GA and HA appear to have a greater impact on OHRQoL than depression.

The effects of psychedelic-assisted therapy on illness and death anxiety: A systematic review and meta-analysis

Illness anxiety (IA) is characterized by worry or fear in response to living with a chronic illness or a preoccupation with having or acquiring a serious disease in conjunction with absent to mild somatic symptomatology. Death anxiety (DA) may underpin IA and is more common in individuals with life-threatening illness. Treatments for DA and IA, such as psychotherapy and antidepressant drugs, are limited. Serotonergic psychedelic assisted therapy (PT) is a promising treatment alternative as it acts more rapidly than antidepressants and has been shown to decrease anxiety associated with life-threatening illness. This meta-analysis aims to systematically analyze PTs efficacy for DA and IA. A literature search of English language publications was conducted through the Ovid database using Medline®, PsychINFO®, and Embase® from date of inception to February 2024. Validated measures were available to assess DA. However, the State Trait Anxiety Inventory (STAI) was the only measure consistently available across studies to assess anxiety. Given the STAI State scale assesses transient anxiety, which may occur as a result of stressful circumstances, we employed it as a measure of anxiety in the context of a life-threatening illness. Five randomized controlled trials were included. The results showed that PT was associated with sustained decreases in DA and State and Trait anxiety in the context of having a life-threatening illness. This meta-analysis highlights PT as a treatment for DA and anxiety in the context of a life-threatening illness. Future studies should attempt to replicate these findings in other contexts, such as IA Disorder and somatic symptom disorders.

Symptom Attributions in Illness Anxiety Disorder

OBJECTIVES

A major characteristic of health anxiety is the tendency to attribute benign bodily sensations to serious illnesses. This has been supported by empirical research in non-clinical samples, and samples of individuals diagnosed with Hypochondriasis. However, no study to date has explored symptom attribution styles of individuals with the DSM-5 diagnosis of Illness Anxiety Disorder.

METHODS

Sixty-one participants, including a clinical Illness Anxiety Disorder (n = 35) and healthy control (n = 26) sample, completed self-report measures of health anxiety and an Attribution Task, whereby they were presented with eight common bodily sensations and asked to generate possible explanations for them.

RESULTS

Results showed that relative to healthy controls, participants with Illness Anxiety Disorder overall were more likely to make more serious, 'catastrophic' somatic attributions to symptoms, and less likely to generate non-threatening normalising explanations. These results also extended to their initial attributions, conceptualised as the 'jumping to conclusions' bias, and as an exploratory index of flexibility, they were also found to make less attributions overall compared to healthy controls.

CONCLUSIONS

Findings provide support for the cognitive behavioural theory of health anxiety, and highlight the importance of assessing and addressing symptom attributions with clients with illness anxiety disorder.

Validation of the Chinese version of the Epilepsy Anxiety Survey Instrument (EASI) and its brief version (brEASI) in Western China

OBJECTIVE

To translate and validate the Chinese version of the Epilepsy Anxiety Survey Instrument (EASI) and its brief version (brEASI) among Chinese people with epilepsy.

METHODS

Adult outpatients from Sichuan Provincial People's Hospital were recruited. The type of anxiety disorder was determined via the Mini International Neuropsychiatric Interview (MINI). All patients completed the Chinese version of the Generalized Anxiety Disorders-7 (GAD-7), the Chinese version of the Neurological Disorders Depression Inventory for Epilepsy (C-NDDIE), and the EASI/brEASI. Cronbach's α coefficient was calculated, and receiver operating characteristic (ROC) curves were analyzed.

RESULTS

A total of 110 patients with epilepsy were included. Twenty-six (23.6 %) patients were found to have anxiety disorder according to the MINI criteria. The Cronbach's α coefficient for the Chinese brEASI was 0.873. In the study, the AUC of the brEASI for detecting all anxiety disorders was 0.883, and the optimal cutoff score was > 7, with a sensitivity of 92.3 % and a specificity of 72.6 %. For the diagnosis of non-GAD disorders, the brEASI had a greater AUC (0. 886) and performed better than the GAD-7 (AUC = 0. 824).

CONCLUSION

The Chinese version of the EASI and brEASI may be reliable and superior to the GAD-7 for anxiety screening in patients with epilepsy.

Global research status and trends of somatic symptom disorder: A bibliometric study

BACKGROUND

With the growing scholarly and clinical fascination with somatic symptom disorder (SSD), a bibliometric analysis is lacking.

AIM

To conduct a bibliometric analysis to investigate the current status and frontiers of SSD.

METHODS

The documents related to SSD are obtained from the web of science core collection database (WoSCC), and VOSviewer 1.6.16 from January 1, 2000 to December 31, 2023, and the WoSCC's literature analysis wire were used to conduct the bibliometric analysis.

RESULTS

A total of 567 documents related to SSD were included, and 2325 authors across 947 institutions from 57 countries/regions have contributed to SSD research, published in 277 journals. The most productive author, institution, country and journal were Löwe B, University of Hamburg, Germany, and Journal of Psychosomatic Research respectively. The first high-cited document was published in the Journal of Psychosomatic Research in 2013 by Dimsdale JE and colleagues, which explored the rationale behind the SSD diagnosis introduction in diagnostic and statistical manual of mental disorders.

CONCLUSION

In conclusion, the main research hotspots and frontiers in the field of SSD are validity and reliability of the SSD criteria, functional impairment of SSD, and the treatment for SSD. More high-quality studies are needed to assess the diagnosis and treatment of SSD.

A Latent Class Analysis of Psychopathology Among Adults in Residential Substance Use Treatment: Associations With Craving and Treatment Dropout

Objective

Adults receiving residential treatment for substance use disorders (SUDs) who have comorbid psychopathology face unique challenges, including an increased risk of substance use craving and treatment dropout against medical advice (AMA). Prior studies have investigated associations between specific forms of psychopathology and these outcomes. However, psychological disorders often co-occur and may cluster together to amplify risk for craving and treatment dropout AMA.

Methods

This study used latent class analysis to identify patterns of psychopathology in 1046 adult patients receiving residential treatment for SUDs (73.7% men; Mage  = 42.31, SD = 12.13). We tested whether psychopathology classes differed in alcohol and drug cravings and treatment dropout AMA. We identified 4 latent classes: (1) high psychopathology, (2) moderate anxiety/depression, (3) illness anxiety/somatic problems, (4) low psychopathology.

Results

The high psychopathology class reported significantly more alcohol and drug cravings than all other classes. The moderate anxiety/depression class also reported more alcohol cravings than the low psychopathology class. Additionally, the high psychopathology, illness anxiety/somatic problems, and moderate anxiety/depression classes had higher proportions of patients who dropped out of treatment AMA compared to the low psychopathology class.

Conclusion

These findings suggest that comorbid psychopathology significantly impacts treatment outcomes in residential SUD treatment programs. Targeted interventions that address comorbid psychopathology may help reduce craving and improve treatment retention.

Health anxiety during a global pandemic: a comparison of medical and non-medical students in Mashhad, Iran

Background

The COVID-19 pandemic has negatively impacted mental health worldwide, especially among healthcare professionals, including medical students, who were more exposed to pandemic-related stressors. However, health anxiety within this vulnerable group remains understudied.

Objective

This study aimed to assess and compare health anxiety and COVID-19 anxiety between medical and non-medical students during the COVID-19 pandemic and to identify factors associated with these forms of anxiety.

Methods

This cross-sectional study recruited Iranian medical and non-medical students studying in Mashhad via convenience sampling using messaging apps. Participants completed a self-reported questionnaire on demographic and social factors, along with the Health Anxiety Inventory (HAI) and the Corona Disease Anxiety Scale (CDAS), with higher scores reflecting greater symptom severity. Statistical analyses evaluated group differences, correlations between HAI and CDAS scores, and the influence of confounding variables.

Results

A total of 305 students participated, with 176 medical students (57.7%) and 129 non-medical students (42.3%). The majority (92.7%) reported mild COVID-19 anxiety, while 3.2% reported moderate and 0.98% reported severe COVID-19 anxiety. COVID-19 anxiety did not significantly differ between medical and non-medical students (P = 0.439). However, medical students reported significantly higher fear of illness consequences than non-medical students (P = 0.037), while no significant differences were found in susceptibility to disease (P = 0.299) or general health concern (P = 0.156). HAI and CDAS scores were significantly correlated (r = 0.30, P < 0.001). Based on logistic regression, Female gender (OR = 4.55, P = 0.002) was associated with susceptibility to health anxiety, while studying a non-medical major was associated with lower health anxiety (OR = 0.01, P < 0.001) and lower COVID-19 anxiety (OR = 0.05, P < 0.001).

Conclusion

Mild COVID-19 anxiety was prevalent among both medical and non-medical students, with comparable levels of health anxiety across the groups. These findings suggest the need for targeted mental health support among students during pandemic conditions.

Measurement Properties of the Patient Health Questionnaire-15 and Somatic Symptom Scale-8: A Systematic Review and Meta-Analysis

Importance

The subjective experience of somatic symptoms is a key concern throughout the health care system. Valid and clinically useful instruments are needed.

Objective

To evaluate the measurement properties of 2 widespread patient-reported outcomes: the Patient Health Questionnaire-15 (PHQ-15) and Somatic Symptom Scale-8 (SSS-8).

Data Sources

Medline, PsycINFO, and Web of Science were last searched February 1, 2024.

Study Selection

English-language studies reporting estimates pertaining to factor analysis, taxometric analysis, internal consistency, construct validity, mean scores in relevant groups, cutoffs, areas under the receiver operating characteristic curves (AUROCs), minimal clinically important difference, test-retest reliability, or sensitivity to change.

Data Extraction and Synthesis

Search hits were reviewed by independent raters. Cronbach α, Pearson r, means, and between-group effect sizes indicative of sensitivity to change were pooled in random-effects meta-analysis. Study quality was assessed using 3 instruments. Reporting followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 reporting guideline.

Main Outcomes and Measures

Comprehensive overview of evidence pertaining to the measurement properties of the PHQ-15 and SSS-8.

Results

A total of 305 studies with 361 243 participants were included. Most concerned routine care (178 studies) and the general population (27 studies). In factor analyses, both scales reflected a combination of domain-specific factors (cardiopulmonary, fatigue, gastrointestinal, pain) and a general symptom burden factor. The pooled PHQ-15 α was 0.81 (95% CI, 0.80-0.82), but with low item-total correlations for items concerning menstrual problems, fainting spells, and sexual problems (item-total correlations <0.40), and the SSS-8 α was 0.80 (0.77-0.83). Pooled correlations with other measures of somatic symptom burden were 0.71 (95% CI, 0.64-0.78) for the PHQ-15 and 0.82 (95% CI, 0.72-0.92) for the SSS-8. Reported AUROCs for identification of somatoform disorders ranged from 0.63 (95% CI, 0.50-0.76) to 0.79 (95% CI, 0.73-0.85) for the PHQ-15 and from 0.71 (95% CI, 0.66-0.77) to 0.73 (95% CI, 0.69-0.76) for the SSS-8. The minimal clinically important difference on both scales was 3 points. Test-retest reliability could not be pooled and was inconsistent for the PHQ-15 (PHQ-15: r = 0.65-0.93; ICC, 0.87; SSS-8: r = 0.996, ICC = 0.89). The PHQ-15 showed tentative sensitivity to change (g = 0.32; 95% CI, 0.08-0.56), but data for the SSS-8 were lacking.

Conclusions and Relevance

In this systematic review and meta-analysis, findings supported use of the PHQ-15 and SSS-8 for the assessment of symptom burden, but users should be aware of the complex, multifactorial structures of these scales. More evidence is needed concerning longitudinal measurement properties.

Development and psychometric properties of the Health Anxiety Behavior Inventory (HABI)

BACKGROUND

Mainstream cognitive behavioural theory stipulates that clinically significant health anxiety persists over time at least partially due to negatively reinforced health-related behaviours, but there exists no broad and psychometrically valid measure of such behaviours.

AIMS

To draft and evaluate a new self-report scale - the Health Anxiety Behavior Inventory (HABI) - for the measurement of negatively reinforced health anxiety behaviours.

METHOD

We drafted the HABI from a pool of 20 candidate items administered in a clinical trial at screening, and before and after cognitive behaviour therapy (n=204). A psychometric evaluation focused on factor structure, internal consistency, convergent and discriminant validity, test-retest reliability, and sensitivity to change.

RESULTS

Based on factor analysis, the HABI was completed as a 12-item instrument with a four-dimensional factor structure corresponding to the following scales: (i) bodily preoccupation and checking, (ii) information- and reassurance-seeking, (iii) prevention and planning, and (iv) overt avoidance. Factor inter-correlations were modest. The internal consistency (α=.73-.87) and 2-week test-retest reliability (r=.75-.90) of the scales was adequate. The bodily preoccupation and checking, and information- and reassurance-seeking scales were most strongly correlated with the cognitive and emotional components of health anxiety (r=0.41, 0.48), and to a lower extent correlated to depressive symptoms and disability. Change scores in all HABI scales correlated with improvement in the cognitive and emotional components of health anxiety during cognitive behaviour therapy.

CONCLUSIONS

The HABI appears to reliably measure negatively reinforced behaviours commonly seen in clinically significant health anxiety, and might be clinically useful in the treatment of health anxiety.

Intrusive Thoughts and Images in Health Anxiety: Rates, Characteristics, and Responses

OBJECTIVES

Intrusive thoughts and images in Health Anxiety are poorly understood. The current study aims to explore the rates and nature of health-related intrusive thoughts and images in people with and without Health Anxiety.

DESIGN

We used a cross-sectional interview and survey design recruiting 82 participants (Health Anxiety: n = 37; control: n = 45).

METHODS

Participants completed a diagnostic and clinical interview, and questionnaires to assess experiences and appraisals of intrusive thoughts and images about health.

RESULTS

Experiencing an intrusive thought or image was common in both groups (Health Anxiety: 89.2%, control: 55.6%). However, the Health Anxiety group reported their intrusive thoughts as more frequent, more distressing, and associated them with more negative emotions than controls. Further, the Health Anxiety group had increased negative appraisals and specific maladaptive behaviours for both intrusive thoughts and intrusive images compared to controls.

CONCLUSIONS

We conclude that, relative to controls, individuals with Health Anxiety experience intrusive thoughts and images more intensely and negatively, have more dysfunctional appraisals of them, and are more likely to respond to them with specific maladaptive behaviours. As such, addressing intrusive thoughts and images as part of cognitive behavioural interventions for Health Anxiety is warranted.

Predictive roles of cognitive biases in health anxiety: A machine learning approach

Prior work suggests that cognitive biases may contribute to health anxiety. Yet there is little research investigating how biased attention, interpretation, and memory for health threats are collectively associated with health anxiety, as well as the relative importance of these cognitive processes in predicting health anxiety. This study aimed to build a prediction model for health anxiety with multiple cognitive biases as potential predictors and to identify the biased cognitive processes that best predict individual differences in health anxiety. A machine learning algorithm (elastic net) was performed to recognise the predictors of health anxiety, using various tasks of attention, interpretation, and memory measured across behavioural, self-reported, and computational modelling approaches. Participants were 196 university students with a range of health anxiety severity from mild to severe. The results showed that only the interpretation bias for illness and the attention bias towards symptoms significantly contributed to the prediction model of health anxiety, with both biases having positive weights and the former being the most important predictor. These findings underscore the central role of illness-related interpretation bias and suggest that combined cognitive bias modification may be a promising method for alleviating health anxiety.

The Relationship between Cyberchondria and Health Anxiety and the Moderating Role of Health Literacy among the Pakistani Public

Following the COVID-19 pandemic, the current study examines the association between cyberchondria and health anxiety in the Pakistani population, with health literacy as a moderator. This study utilized a cross-sectional research approach, with data gathered through simple random sampling. The study enlisted 1295 participants from Pakistan aged between 18 and 70, 63% of whom were male and 36% of whom were female. The researchers found a statistically significant positive link between cyberchondria and health anxiety (β = 0.215; t = 1.052; p 0.000). The moderating influence of health literacy suggests that health anxiety has a significantly negative effect on the relationship between cyberchondria and health anxiety (β = -0.769; t = 2.097; p 0.037). Moreover, females had higher cyberchondria scores than males. Health-related anxiety did not differ between the sexes, and males had greater health literacy than females. These results emphasize the critical role of health literacy in the moderating effects of cyberchondria on health anxiety. Furthermore, they reveal significant gender differences in both cyberchondria and health literacy.

Association of general anxiety and pediatric dental preventive examination utilization, National Survey of Children's Health, 2021

INTRODUCTION

Many factors influence preventive dental health service access for children. The objective of this research was to examine one factor, general anxiety, in accessing at least one preventive dental examination in the past 12 months in children with special healthcare needs (CSHCN) and children without special healthcare needs (CWSHCN).

METHODS

National Survey of Children's Health (NSCH) 2021 were obtained for this cross-sectional research. Chi-square and logistic regression analyses were used to determine association of anxiety and past 12-month preventive dental examinations.

RESULTS

The sample included 10 493 CSHCN, and 35 675 CWSHCN. Overall, 72.7% had past 12-month preventive dental examinations, and 9.9% had a healthcare provider indicate they had general anxiety. CSHCN with anxiety, CWSHCN with anxiety, and CSHCN without anxiety were more likely to have a past 12-month preventive dental examination visit than CWSHCN without anxiety (Adjusted Odds Ratios: 1.86, 1.39, 1.32, respectively).

CONCLUSION

Our results suggest children with general anxiety (both CSHCN and CWSHCN) are more likely to have had at least one regular preventive dental visit within the past 12 months than CWSHCN and without general anxiety. There is a need for further understanding the relationship of general anxiety and dental health to improve the health of all children.

PRACTICAL IMPLICATIONS

CWSHCN without anxiety need individualized, comprehensive care with enough time, attention, instruction, and rewards to demonstrate to parents/guardians the importance of making routine preventive dental examinations a priority for their child.

Illness Anxiety Disorder: A Review of the Current Research and Future Directions

PURPOSE OF REVIEW

We review recent evidence on Illness Anxiety Disorder (IAD), including risk factors and precipitants, diagnostic classification, clinical characteristics of the disorder, and assessment and treatment in both children and adults.

RECENT FINDINGS

IAD places a substantial burden on both individuals and society. Despite its impact, understanding of the disorder is lacking and debates remain about whether IAD should be classified as an anxiety disorder and whether it is distinct from Somatic Symptom Disorder. Cognitive behavioural therapy (CBT) is an effective treatment for IAD and there are multiple validated measures of health anxiety available. However, research on health anxiety in children and youth is limited. IAD is chronic, and debilitating, but when identified, it can be effectively treated with CBT. Research using DSM-5 IAD criteria is lacking, and more research is needed to better understand the disorder, particularly in children and youth.

Putting the Vicious Cycle to the Test: Evidence for the Cognitive Behavioral Model of Persistent Somatic Symptoms From an Online Study

OBJECTIVE

In clinical practice, persistent somatic symptoms are regularly explained using a cognitive-behavioral model (CBM). In the CBM, predisposing, perpetuating, and precipitating factors are assumed to interact and to cause the onset and endurance of somatic symptoms. However, these models are rarely investigated in their entirety.

METHODS

We conducted an online survey during the COVID-19 pandemic. A total of 2114 participants from the general German population completed questionnaires that measured different factors of the CBM. We used state negative affectivity and neuroticism as predisposing factors, fear of a COVID-19 infection as the precipitating factor, and somatic symptoms, misinterpretation of bodily symptoms, attention allocation to bodily symptoms, and health anxiety as perpetuating factors. Moreover, we added safety and avoidance behavior as end points to the model. We conducted a psychological network analysis to exploratively study the relationships between the model's different factors and tested the assumptions of the CBM by evaluating a structural equation model (SEM) that incorporated all factors of the model.

RESULTS

Network analyses revealed clustering in our data: Health anxiety and different cognitive factors are closely related, whereas somatic symptoms and state negative affectivity are strongly associated. Our SEM showed adequate fit.

CONCLUSIONS

Our findings from an exploratory and a confirmatory approach give empirical support for the CBM, suggesting it as a suitable model to explain bodily symptoms in the general population and to possibly guide clinical practice. The network model additionally indicates the necessity to apply an individualized CBM for patients, depending on a preponderance of either persistent somatic symptoms or health concerns.

Phenomenology of Somatization in Immigrants: An Idealtypical Approach

INTRODUCTION

Somatization in immigrants is frequent but standard studies do not differentiate between various forms of somatization. In this qualitative study, we used an idealtypical approach with the aim of phenomenologically differentiating between different forms of somatization in immigrants.

METHODS

The clinical description of the ideal types was based on seven levels: medical examination; description of somatization symptoms; the patients' own interpretation of their somatic experience; concomitant psychopathological phenomena; genetic understanding; clinician's interpretation; and course and treatment.

RESULTS

Five different ideal typologies of patients emerged: anxious hypochondriasis, somatization with cultural features playing a pathogenetic role, culturally shaped somatization (through pathoplastic effects), somatization as part of adjustment reactions due to migratory living difficulties, and somatization as post-traumatic reaction.

CONCLUSION

These differences are useful to highlight the complex interrelationship between socioeconomic, migratory, cultural, and value factors in the construction of somatization among immigrants. Implications for research methodology, nosology, clinical management, and organization of medical facilities are also discussed.

Loneliness, Social Isolation, and Obsession with COVID-19 among Older Adults

During the COVID-19 pandemic, older people were socially isolated for their protection against the virus impacting their mental health. Aiming to explore the role of loneliness and social isolation in the obsession with COVID-19 among older adults, we conducted an anonymous online survey with 300 older adults aged 65-80 years in South Korea between January and February 2023. The survey collected demographic information, past psychiatric history, medical disease, current psychological distress, and experiences related to COVID-19. Rating scales were the Obsession with COVID-19 Scale (OCS), Coronavirus Reassurance-seeking Behaviors Scale (CRBS), Stress and Anxiety to Viral Epidemics-6 items (SAVE-6), and Loneliness and Social Isolation Scale (LSIS). The regression analysis revealed that CRBS (β = 0.55, p < 0.001) and SAVE-6 (β = 0.34, p < 0.001) were significant predictors of obsession with COVID-19 (adjusted R2 = 0.63, F = 126.9, p < 0.001). Mediation analysis showed that loneliness and social isolation had a positive total effect on obsession with COVID-19, mediated by reassurance-seeking behavior and viral anxiety (Standardized Estimator = 0.21, standard error = 0.05, p < 0.001, 95% confidence interval 0.20-0.41). Loneliness and social isolation were found to be indirectly linked to obsession with COVID-19 through reassurance-seeking behavior and viral anxiety. The findings highlight the importance of addressing loneliness and social isolation among older adults during the COVID-19 pandemic to prevent obsession with COVID-19.

Psychological risk factors of somatic symptom disorder: A systematic review and meta-analysis of cross-sectional and longitudinal studies

OBJECTIVE

Current diagnostic concepts of somatic symptom disorder (SSD) in DSM-5 and bodily distress disorder (BDD) in ICD-11 require certain psychological criteria, but researchers have called for further specification. Therefore, in a first step, this systematic review and meta-analysis aimed to summarize the current evidence on psychological factors associated with SSD/BDD and/or disorder-relevant clinical outcomes such as symptom severity and impairment.

METHODS

Psychological factors were systematically searched using Pubmed, Cochrane Library and Psycinfo via EBSCO. Studies providing original data in English or German, after 2009 were included. Cross-sectional, cohort and case-control studies investigating at least one psychological factor in individuals with SSD/BDD in the context of disorder-relevant outcomes were included.

RESULTS

Forty-three eligible studies (n = 3760 patients) in SSD (none in BDD) provided data on at least one psychological factor, 37 in case-control format, 10 cross-sectional and 5 longitudinal. Meta-analyses of the case-control studies found patients with SSD to be more impaired by depression (SMD = 1.80), anxiety (SMD = 1.55), health anxiety (SMD = 1.31) and alexithymia (SMD = 1.39), compared to healthy controls. Longitudinal results are scarce, mixed, and require refining, individual studies suggest self-concept of bodily weakness, anxiety and depression to be predictive for persistent SSD and physical functioning.

CONCLUSION

This review provides a detailed overview of the current evidence of psychological factors in relation to SSD/BDD. Future studies on SSD and BDD should include under-studied psychological factors, such as negative affect, fear avoidance, or emotion regulation. More longitudinal studies are needed to assess the predictive value of these factors.

Frontal alpha asymmetry is associated with chronic stress and depression, but not with somatoform disorders

Cardinal characteristics of somatoform disorders (SFDs) are worry of illness, and impaired affective processing. We used relative frontal alpha asymmetry (FAA), a method to measure functional lateralization of affective processing, to investigate psychobiological correlates of SFDs. With alpha activity being inversely related to cortical network activity, relative FAA refers to alpha activity on the right frontal lobe minus alpha activity on the left frontal lobe. Less relative left frontal activity, reflected by negative FAA scores, is associated with lower positive and greater negative affectivity, such as observed in depression. Due to its negative affective component (illness anxiety), we expected to find less relative left frontal activity pattern in SFDs, and positive associations with self-reported chronic stress and depression symptoms. We recorded resting-state EEG activity with 64 electrodes, placed in a 10-10 system in 26 patients with a primary SFD, 23 patients with a major depressive disorder and 25 healthy control participants. The groups did not differ in FAA. Nevertheless, across all participants, less relative left frontal activity was associated with chronic stress and depression symptoms. We concluded that FAA may not serve as an indicator of SFDs. As the relationship of FAA and depressive symptoms was fully mediated by chronic stress, future studies have to clarify whether the association between FAA and chronic stress may represent a shared underlying factor for the manifestation of mental health complaints, such as depression.

Care trajectories of individuals with anxiety disorders: A retrospective cohort study

BACKGROUND

Anxiety disorders (ADs) are associated with increased healthcare use (HCU), and individuals may seek healthcare through various pathways according to clinical and individual characteristics. This study aimed to characterize care trajectories (CTs) of individuals with ADs.

METHODS

This is a retrospective cohort study using the Care Trajectories - Enriched Data cohort, a linkage between the Canadian Community Health Surveys (CCHS), and health administrative data from Quebec. The cohort included 5143 respondents reporting ADs to the CCHS between 2009 and 2016. We measured CTs over 5 years before CCHS using a state sequence analysis.

RESULTS

The cohort was categorized into five types of CTs. Type 1 (52.7 %) was the lowest care-seeking group, with fewer comorbidities. Type 2 (24.0 %) had higher levels of physical and mental health comorbidities and moderate HCU, mainly ambulatory visits to general practitioners. Type 3 (13.1 %) represented older patients with the highest level of physical illnesses and high HCU, predominantly ambulatory consultation of specialists other than psychiatrists. Types 4 and 5 combined young and middle-aged patients suffering from severe psychological distress. HCU of type 4 (6.7 %) was high, mainly consultations of ambulatory psychiatrists, and HCU of type 5 (3.5 %), was the highest and mostly in acute care.

LIMITATIONS

Administrative and survey data may have coding errors, missing data and self-report biases.

CONCLUSION

Five types of CTs showed distinct patterns of HCU often modulated by physical and mental health comorbidities, which emphasizes the importance of considering ADs when individuals seek care for other mental health conditions or physical illness.

All-Cause and Cause-Specific Mortality Among Individuals With Hypochondriasis

Importance

Hypochondriasis, also known as health anxiety disorder, is a prevalent, yet underdiagnosed psychiatric disorder characterized by persistent preoccupation about having serious and progressive physical disorders. The risk of mortality among individuals with hypochondriasis is unknown.

Objective

To investigate all-cause and cause-specific mortality among a large cohort of individuals with hypochondriasis.

Design, Setting, and Participants

This Swedish nationwide matched-cohort study included 4129 individuals with a validated International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) diagnosis of hypochondriasis assigned between January 1, 1997, and December 31, 2020, and 41 290 demographically matched individuals without hypochondriasis. Individuals with diagnoses of dysmorphophobia (body dysmorphic disorder) assigned during the same period were excluded from the cohort. Statistical analyses were conducted between May 5 and September 27, 2023.

Exposure

Validated ICD-10 diagnoses of hypochondriasis in the National Patient Register.

Main Outcome and Measures

All-cause and cause-specific mortality in the Cause of Death Register. Covariates included birth year, sex, county of residence, country of birth (Sweden vs abroad), latest recorded education, civil status, family income, and lifetime psychiatric comorbidities. Stratified Cox proportional hazards regression models were used to estimate the hazard ratios (HRs) and 95% CIs of all-cause and cause-specific mortality.

Results

Of the 4129 individuals with hypochondriasis (2342 women [56.7%]; median age at first diagnosis, 34.5 years [IQR, 26.3-46.1 years]) and 41 290 demographically matched individuals without hypochondriasis (23 420 women [56.7%]; median age at matching, 34.5 years [IQR, 26.4-46.2 years]) in the study, 268 individuals with hypochondriasis and 1761 individuals without hypochondriasis died during the study period, corresponding to crude mortality rates of 8.5 and 5.5 per 1000 person-years, respectively. In models adjusted for sociodemographic variables, an increased rate of all-cause mortality was observed among individuals with hypochondriasis compared with individuals without hypochondriasis (HR, 1.69; 95% CI, 1.47-1.93). An increased rate was observed for both natural (HR, 1.60; 95% CI, 1.38-1.85) and unnatural (HR, 2.43; 95% CI, 1.61-3.68) causes of death. Most deaths from unnatural causes were attributed to suicide (HR, 4.14; 95% CI, 2.44-7.03). The results were generally robust to additional adjustment for lifetime psychiatric disorders.

Conclusions and Relevance

This cohort study suggests that individuals with hypochondriasis have an increased risk of death from both natural and unnatural causes, particularly suicide, compared with individuals from the general population without hypochondriasis. Improved detection and access to evidence-based care should be prioritized.

The Prevalence of Illness Anxiety Disorder Among Adults in Taif City, Saudi Arabia: A Cross-Sectional Study

Introduction Illness Anxiety Disorder (IAD), characterized by intense fear of serious illness, has been associated with performance issues at work, frequent absences, financial burdens from medical expenses, impaired daily functioning, and the onset and recurrence of coronary heart disease. This study aimed to assess the prevalence of IAD and explore its cardiac manifestations in residents of Taif City, Saudi Arabia. Methods A descriptive cross-sectional study was conducted among adults in Taif City, excluding those with psychiatric illnesses. Participants completed an online self-administered questionnaire, including sociodemographic information and the validated Short Version Health Anxiety Inventory (SHAI) scale. Results Among 415 participants, predominantly females (60%), the study found a 25.3% prevalence of IAD. Of those with IAD, 3% were diagnosed with cardiac diseases, and 27% were hospitalized due to cardiac symptoms. Twenty-five percent exhibited normal examination results after hospitalization. Factors such as female gender (p=0.006), younger age (p=0.006), single marital status (p=0.012), and a history of hospitalization due to heart symptoms (p=0.003) were associated with higher IAD scores. Married participants had a lower risk of IAD compared to singles (OR: -2.2, 95% CI: -3.9, -0.48), while a history of hospitalization due to heart symptoms increased the risk of IAD (OR: 2.8, 95% CI: 0.94, 4.7). Conclusion This study revealed a substantial prevalence of IAD in Taif City. Female gender, younger age, being single, and having a history of hospitalization due to heart symptoms were identified as determinants of IAD. Healthcare providers must recognize these disorders to prevent unnecessary investigations and treatments, redirecting patients to psychiatry for more cost-effective and beneficial interventions.

Respiratory Interoception and Pathological Illness Anxiety: Disentangling Bias

OBJECTIVE

Biased interoception decoupled from physiology might be relevant in the etiology of pathological illness anxiety (PIA). Empirical evidence for interoceptive deviations in illness anxiety is scarce but potentially informative to optimize treatments. We hypothesized that persons with PIA differ fundamentally in the classification of bodily sensations from those without PIA.

METHODS

In a respiratory categorization task, participants breathed into a pulmonary training device. Inspiration effort was varied by eight resistive loads. The lower/higher four loads were introduced as belonging to arbitrary categories "A"/"B," respectively. Participants memorized respiratory sensations in a first experimental block and were asked to label the resistances in a second block. We calculated the sensitivity of resistance classification according to category and response bias in terms of categorical misclassification. Data of 39 participants with PIA and 35 controls were compared with regard to sensitivity and response bias by group, resistive load, and their interaction in a multiple regression.

RESULTS

With similar sensitivity, patients more often labeled loads above the categorical border erroneously as belonging to category A, thus underestimating their resistance ( β = -0.06, p = .001; η2 = 0.02).

CONCLUSIONS

Individuals with PIA showed a systematic "wait and see" approach. Altered respiroception in PIA might stem from biased perception during training phase, the recognition phase, biased memory, or a combination of these. Its exact characteristics remain unknown, and future research must address the challenge of developing reliable and valid paradigms accounting for the variability of interoceptive biases.

Somatic Symptom Disorder and Health Anxiety: Assessment and Management

The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) Somatic Symptom Disorder (SSD) and Illness Anxiety Disorder (IAD) replaced the diagnostic entities of the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) somatoform disorders and hypochondriasis. SSD turns away from specifying the presence or absence of a medical condition for presented symptoms and instead focuses on excessive symptom-related affects, cognitions, and behaviors. People with pathological health anxiety can be diagnosed with SSD or IAD, depending on the intensity of accompanying somatic symptoms. Cognitive-behavioral therapy shows the best empirical evidence for an effective treatment of SSD and IAD.

Longevity of Post-Explantation Systemic Symptom Improvement and Potential Etiologies: Findings From the ASERF Systemic Symptoms in Women-Biospecimen Analysis Study: Part 4

BACKGROUND

Breast Implant Illness (BII) describes a variety of symptoms reported by patients with breast implants. Biospecimens data revealed minimal statistical differences between BII and non-BII cohorts. Baseline analysis of PROMIS data demonstrated significant differences between the BII cohort and the 2 control cohorts.

OBJECTIVES

This study was designed to determine if patients in the BII cohort obtained any symptom improvement after explantation, whether symptom improvement was related to the type of capsulectomy, and which symptoms improved.

METHODS

A prospective blinded study enrolled 150 consecutive patients divided equally into 3 cohorts. Baseline demographic data and a systemic symptoms survey, including PROMIS validated questionnaires, were obtained at baseline, 3 to 6 weeks, 6 months, and 1 year.

RESULTS

A total of 150 patients were enrolled between 2019 and 2021. Follow-up at 1 year included 94% of the BII cohort and 77% of non-BII and mastopexy cohorts. At 1 year, 88% of patients showed at least partial symptom improvement, with a reduction of 2 to 20 symptoms. The PROMIS score in the BII cohort decreased at 1 year for anxiety, sleep disturbances, and fatigue. Systemic symptom improvement was noted out to 1 year in the BII cohort regardless of the type of capsulectomy performed.

CONCLUSIONS

Parts 1-3 in this series concluded that there were no consistent differences in biospecimen results between the cohorts. Unlike the data observed in the biospecimen analysis, BII patients had heightened symptoms and poorer PROMIS scores at baseline compared to the control cohorts. The reduction of negative expectations and a potential nocebo effect could contribute to this improvement.

Joint factor analysis and approximate equipercentile linking of common trait health anxiety measures: a cross-sectional study of the 14-, 18- and 64-item health anxiety inventory, the illness attitude scale, and the 14-item Whiteley Index

BACKGROUND

Research on health anxiety has bloomed in recent years, but summaries of the literature are complicated by the use of dissimilar self-report questionnaires. Furthermore, these instruments have rarely been administered in parallel, and especially not in clinical samples. In this study, we aimed to investigate the relationship between five widespread health anxiety measures, and to draft guidelines for the conversion of different sum scores.

METHODS

Clinical trial participants with principal pathological health anxiety (n = 335) and a sample of healthy volunteers (n = 88) completed the 14-item Whiteley Index (WI-14), the Illness Attitude Scale (IAS), and the 14-, 18-, and 64-item Health Anxiety Inventory (the HAI-64, HAI-18, and HAI-14). Cross-sectional data from all participants were pooled (N = 423) and we conducted a joint factor analysis and approximate equipercentile linking of the WI-14, IAS, HAI-64, HAI-18, and HAI-14.

RESULTS

Inter-scale correlations were high (rs ≥ 0.90 and ≥ 0.88 in adjusted analyses), and the scree plot of the joint factor analysis spoke for a unifactorial solution where 89/105 items (85%) had loadings ≥ 0.40. Most items at the core of this broad trait health anxiety factor pertained to the worry about health, the fear of having or developing a serious disease, and to some extent bodily preoccupation. We present a cross-walk table of observed equipercentile linked sum scores.

CONCLUSIONS

This study speaks clearly in favor of the WI-14, IAS, HAI-64, HAI-18, and HAI-14 all tapping into the same trait health anxiety construct, the core of which appears to concern the worry about health, the fear of having or developing a serious disease, and to some extent bodily preoccupation. Based on recently reported cut-offs for the HAI-14, a reasonable cutoff for pathological health anxiety in a psychiatric setting probably lies around 7-8 on the WI-14, 52-53 on the IAS, 82-83 on the HAI-64, and 26-27 on the HAI-18.

Managing Rumination and worry: A randomised controlled trial of an internet intervention targeting repetitive negative thinking delivered with and without clinician guidance

BACKGROUND

Rumination and worry, forms of repetitive negative thinking (RNT), are implicated in the onset, maintenance, severity, and relapse risk of depression and anxiety disorders. This randomised controlled trial evaluated an internet intervention targeting both rumination and worry in adults compared to treatment-as-usual (TAU) and compared treatment effects and adherence when delivered with and without clinician guidance.

METHODS

Adults (N = 137) with elevated RNT were randomly allocated to a 3-lesson clinician guided (n = 45) or self-help (n = 47) online program delivered over 6 weeks, or a TAU control group which waited 18 weeks to receive the program (n = 45). The clinician guided group received semi-structured phone support after each lesson. All three groups continued any pre-trial TAU. RNT, anxiety, depression, and psychological distress were assessed at baseline, post-treatment (week 7), and 3-month follow-up.

RESULTS

Intention-to-treat linear mixed models showed that participants in the self-help and clinician guided groups had significantly lower RNT, anxiety, depression, and distress at post-treatment and 3-month follow-up compared to TAU. Treatment effects were significantly larger in the clinician guided group compared to self-help (between-group gs = 0.41-0.97). No significant between-group differences were found in adherence/program completion (guided: 76%; self-guided: 79%) or treatment satisfaction (1-5 scale: guided: M = 4.17, SD = 1.20; self-guided: M = 3.89, SD = 0.93). Total time spent on clinician guidance was M = 48.64 min (SD = 21.28).

CONCLUSION

This brief online intervention for RNT is acceptable and efficacious in reducing RNT, anxiety, depression, and distress in both clinician guided and self-help formats. The program appeared most effective when delivered with clinician guidance. Larger definitive trials comparing guided and self-guided programs are needed.

Scoping review update on somatic symptom disorder that includes additional Chinese data

Somatic symptom disorder (SSD) is a new diagnosis introduced into the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), which is expected to solve the diagnostic difficulties of patients with medically unexplained symptoms. Based on the previous work, this review aims to comprehensively synthesise updated evidence related to SSD from recent years in English publications and, more extensively, from data published in Chinese language journals. The scoping review update was based on an earlier scoping review and included Chinese language publication data from China National Knowledge Internet (CNKI), WANFANG and WEIPU between January 2013 and May 2022 and data from PubMed, PsycINFO, and Cochrane Library between June 2020 and May 2022. Initially, 2 984 articles were identified, of which 63 full texts were included for analysis. In China, SSD is mainly applied in scientific research, but it also shows good predictive validity and clinical application potential. The mean frequency of SSD was 4.5% in the general population, 25.2% in the primary care population and 33.5% in diverse specialised care settings. Biological factors, such as brain region changes and heart rate variability, are associated with the onset of SSD. Psychological impairment related to somatic symptoms is the best predictor of prognosis. While adolescent SSD was significantly associated with family function, SSD overall is associated with an increased dysfunction of cognition and emotion, decreased quality of life, and high comorbidity with anxiety and depressive disorders. Further research is needed on suicide risk and cultural and gender-related issues. Updating the data of Chinese language studies, our research enriches the evidence-based findings related to the topics addressed in the text sections of the SSD chapter of DSM-5. However, research gaps remain about SSD reliability, population-based prevalence, suicide risk, and cultural and gender-related issues.

Functional Somatic Disorders, Their Subtypes, and Their Association With Self-Rated Health in the German General Population

OBJECTIVE

The heterogeneous conceptualizations and classifications of persistent and troublesome physical symptoms impede their adequate clinical management. Functional somatic disorder (FSD) is a recently suggested interface concept that is etiologically neutral and allows for dysfunctional psychobehavioral characteristics as well as somatic comorbidity. However, its prevalence and impact are not yet known.

METHODS

We analyzed 2379 participants (mean age = 48.3 years, 52.5% female) from a representative German community survey using operationalized FSD criteria. These criteria defined FSD types based on somatic symptom count, type, and severity assessed by the Bodily Distress Syndrome Checklist. In addition, the associations of those types with health concerns, comorbidity, psychological distress, and self-rated health were determined.

RESULTS

There were four clearly demarcated groups with no relevant bothering symptoms, with one or with few bothering symptoms from one organ system, and with multiple bothering symptoms from at least two organ systems. Psychological distress, health concerns, and comorbidity steadily increased, and self-rated health decreased according to the number and severity of symptoms. Somatic symptom burden, health concerns, and comorbidity independently predicted self-rated health, with no interaction effect between the latter two.

CONCLUSIONS

Our data support an FSD concept with two severity grades according to persistent and troublesome symptoms in one versus more organ systems. The delimitation of subtypes with psychobehavioral characteristics and/or with somatic comorbidity seems useful, while still allowing the demarcation of a group of participants with high symptom burden but without those additional characteristics.

Co-occurring insomnia and anxiety: a randomized controlled trial of internet cognitive behavioral therapy for insomnia versus internet cognitive behavioral therapy for anxiety

STUDY OBJECTIVES

Insomnia and anxiety are highly prevalent and frequently co-occur. Given limited therapeutic resources and time constraints, the aim of this study was to compare which treatment-internet cognitive behavioral therapy (CBT) for insomnia or internet CBT for anxiety-leads to the best outcomes in individuals with comorbid insomnia and anxiety.

METHODS

120 participants with comorbid insomnia and clinical anxiety (as defined by scores above the clinical cutoff on the insomnia severity index (ISI) and the generalized anxiety disorder 7-item scale (GAD-7)) were randomized to receive internet-based cognitive behavioral therapy (iCBT) for insomnia or iCBT for anxiety. The primary outcome measures were the ISI and the generalized anxiety disorder 7-item scale. Primary outcome measures were assessed before treatment, at mid-treatment, at post-treatment, and 3 months after treatment. Secondary outcome measures assessed depression symptoms, distress, and sleep diary parameters.

RESULTS

Participants in both groups experienced large reductions in symptoms of insomnia, anxiety, depression, and distress, as well as improvements in sleep efficiency and total sleep time. Improvements were maintained at follow-up. Crucially, at the end of treatment, the insomnia treatment was more effective in reducing symptoms of insomnia than the anxiety treatment, and equally effective in reducing symptoms of anxiety. Treatment gains were maintained at 3-month follow-up, however, there were no differences between groups at that time point.

CONCLUSIONS

These results suggest that in the common case of a patient presenting with comorbid insomnia and anxiety, treatment for insomnia may be the most efficient treatment strategy.

Validity and clinical utility of distinguishing between DSM-5 somatic symptom disorder and illness anxiety disorder in pathological health anxiety: Should we close the chapter?

OBJECTIVE

To investigate the validity and clinical utility of distinguishing between DSM-5 somatic symptom disorder (SSD) and illness anxiety disorder (IAD) in pathological health anxiety: the excessive and recurrent fear of, or preoccupation with, having or developing a serious health condition.

METHODS

We compared SSD to IAD in pathological health anxiety (N = 334) with regard to concurrent, antecedent, and predictive validators. This was primarily a cross-sectional study, though we studied the effect of CBT longitudinally. Because we were interested in the discriminatory value of SSD and IAD over and above trait health anxiety, we used trait health anxiety as a covariate.

RESULTS

SSD (68%; 228/334) vs. IAD (32%; 106/334) differences were mostly non-significant and small in sociodemographics, core clinical characteristics, apparent course, etiological attribution, and physician visits (gs = -0.18-0.20; RRs = 0.84-1.09; IRRs = 0.87-0.99). However, SSD was associated with a significantly higher somatic symptom burden (gs = 0.20-0.72), more psychologist visits (IRR = 2.02, 95% CI: 1.24-3.28), and slightly higher disability (g = 0.22, 95% CI: 0.03-0.42). There was no significant difference in symptom reduction during CBT (g = -0.16, 95% CI: -0.37-0.05).

CONCLUSION

Although not all differences between SSD and IAD in pathological health anxiety seem to be explained by the level of trait health anxiety, the SSD vs. IAD distinction appears to convey little useful information in pathological health anxiety. Tentatively, considering the well-documented clinical characteristics and effective clinical interventions, it is probably most helpful to regard pathological health anxiety as a de facto anxiety or perhaps obsessive-compulsive spectrum disorder, regardless of the DSM-5 diagnosis of SSD or IAD.

Health Anxiety by Proxy Disorder: A Case Report

Health anxiety by proxy (HAP) is a newly introduced term in psychiatry to describe the anxious feelings or fear of having or acquiring a serious illness. It is often accompanied by maladaptive illness behavior in the absence of true somatic symptoms. This, in turn, entails seeking medical advice and therefore doing many unnecessary investigations in an attempt to justify these symptoms. Functional impairment may appear in HAP patients, and this indicates a pathological point. To some extent, it can be said that HAP is similar to health anxiety disorder in terms of symptomatology and items. However, it is imposed on another (usually the patients' children) instead of the patient himself. Many biopsychosocial factors are suggested to play a role in the psychopathology of HAP. Until now, there are no well-established criteria in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR) or International Classification of Diseases 11^th Revision (ICD-11) to make the diagnosis of health anxiety by proxy. Although treatment protocols are missing, it appears that patients are not responding to treatment protocols for illness anxiety disorder. This requires focusing attention on conducting studies on those patients to develop clear treatment plans to help patients. In this report, we present a 28-year-old female with constant worries about her child's health, which subsequently resulted in seeking medical advice at multiple clinics with different medical specialties. Many factors were thought to be implicated in triggering her current condition. The anxious feelings reflected negatively on the patient's life, resulting in a poor functioning status. A treatment plan was initiated with a dismal response and fluctuating course. Additionally, we discussed the initial definition and the bases that could be used to facilitate the diagnosis and management of HAP disorder.

Case report: New insights into persistent chronic pelvic pain syndrome with comorbid somatic symptom disorder

Chronic pelvic pain syndrome (CPPS) is generally defined as pain in the pelvic area that persisted for 3-6 months or longer. The pain can be constant or episodic and functionally disabling. Any dysfunction of the central nervous system can lead to central sensitization, which enhances and maintains pain as well as other symptoms that are mediated by the central nervous system. It occurs in subgroups of nearly every chronic pain condition and is characterized by multifocal pain and co-occurring somatic symptoms. Somatic symptom disorder (SSD) is defined as a condition in which having one or more somatic symptoms, such as excessive worries, pressure, and catastrophic events. These symptoms can be very disruptive to a patient's life and can cause significant distress. SSD cases with severe symptoms frequently undergo repeated medical investigations and the symptoms often lead patients to seek emergency medical treatment and consult with specialists repeatedly, which is a source of frustration for patients and clinicians. Here we report a case that Asian female with persistent CPPS with comorbid SSD, who got in trouble for up to 8 years. This case reminds clinicians to pay excessive attention to the diagnosis of CPPS with comorbid SSD after recovery from acute COVID-19, with hope of raising awareness in the identification of SSD and present new insight into appropriate treatment for each woman who suffers from it.

Meta-analysis of cognitive behaviour therapy and selective serotonin reuptake inhibitors for the treatment of hypochondriasis: Implications for trial design

BACKGROUND

Classification of hypochondriasis as an obsessive-compulsive and related disorder in the International Classification of Diseases 11th Revision (ICD-11) has generated new heuristics for treatment of this common, chronic and disabling disorder. Standard treatment involves cognitive behaviour therapy (CBT) or selective serotonin reuptake inhibitors (SSRIs), but no meta-analysis has so far considered hypochondriasis as a structured diagnosis or assessed the role of medication. A clearer understanding of the relative effectiveness of these interventions and identification of clinically relevant factors moderating the treatment response is needed for clinical guideline development.

METHODS

The current systematic review and meta-analysis of interventions for hypochondriasis was preregistered on PROSPERO (CRD42020185768) and follows PRISMA guidelines. We searched MEDLINE, PsycINFO, and Cochrane Library databases until July 2021 for randomized controlled trials (RCTs) of interventions for patients diagnosed with hypochondriasis (or historical diagnostic equivalents). We assessed aspects of study quality using: the CONSORT Checklist for evaluation of RCTs, the Cochrane Risk of Bias 2 tool, researcher allegiance and treatment fidelity. The primary outcome was improvement in hypochondriasis symptoms, comparing intervention and control groups at trial endpoint. Moderator variables were assessed using subgroup and meta-regression analyses.

RESULTS

Searches identified 13 randomised controlled trials (RCTs) (N = 1405); 12 included CBT (N = 1212) and three included SSRI (N = 193) arms as the experimental intervention. Random effects meta-analysis yielded a moderate-to-large effect size for CBT versus all controls (g = -0.70 [95% CI -0.99 to -0.41], k = 18, I² = 81.1%). Funnel plot asymmetry indicated possible publication bias and two potentially missing trials, reducing the effect size (g = -0.60 [95% CI -0.88 to -0.32]). Subgroup analysis showed that choice of control significantly moderated effect size, with those in CBT vs. wait-list (g = -1.32 [95% CI -1.75 to -0.90], k = 7, I² = 0%) being double those of CBT vs. psychological or pharmacological placebo controls (g = -0.58 [95% CI -0.95 to -0.22], k = 7, I² = 82%). Analysis of studies directly comparing CBT and SSRIs found a numerical, but not statistical advantage for SSRIs (g = 0.21 [95% CI -0.46 to 0.87], k = 2, I² = 58.34%) and a modest effect size emerged for SSRIs vs. pill placebo (g = -0.29 [95% CI -0.57 to -0.01], k = 3, I² = 0%). Most studies (11/13) were rated as high on potential researcher allegiance bias in favour of CBT. Meta-regressions revealed that effect sizes were larger in younger participants, and smaller in better quality and more recent RCTs and those with greater CBT fidelity.

CONCLUSION

CBT and SSRIs are effective in the acute treatment of hypochondriasis, with some indication that intervention at a younger age produces better outcomes for CBT. In the case of CBT, effect sizes appear to have been significantly inflated by the use of wait list controls, and researcher allegiance bias. We recommend that a definitive, adequately controlled trial, designed with respect to the methodological issues raised in this meta-analysis, is needed to determine the magnitude effects for CBT and SSRIs with confidence and the long-term effect of treatments, to inform mental health service provision for this overlooked patient group.

Associations of Mental Health Measures and Retention in a Community-Based Perinatal Care Recovery Support Program for Women of Childbearing Age With Substance Use Disorder

Objective: This research was undertaken to evaluate factors related to program retention among participants in a community-based peer recovery program for women of childbearing age with a history of substance use disorder. Methods: In all, 184 women of childbearing age with a history of substance use disorder were enrolled in a community-based peer recovery program. Half of the participants were pregnant or postpartum. The outcome of interest was retention in the program as measured at 2 and 6 months. Participants were paired with a peer recovery coach (PRC). PRCs were women with a personal history of substance use disorder who assisted with healthcare system navigation, facilitated access to local resources, and provided advice and emotional support. All PRCs were also licensed perinatal community health workers. Independent variables included gestational status, depression, anxiety, type and frequency of substance use, childhood trauma, abuse, readiness for treatment, and attachment patterns. Results: Anxiety was found to be a key factor associated with retention. Moderate anxiety was associated with higher rates of retention compared to normal to mild anxiety. Severe anxiety was associated with lower rates of retention compared to normal to mild anxiety. Attrition was highest in the first 2 months. Conclusions: Early integration with mental health services to address severe anxiety symptoms could potentially improve retention in substance use disorder recovery programs, thereby improving outcomes. More research is needed regarding severe anxiety and care-avoidant behaviors, particularly among women of childbearing age.

Ethnic and migration-related inequalities in health anxiety: A systematic review and meta-analysis

Background

Health anxiety exists on a continuum ranging from the absence of health awareness to the obsessive fear of having a serious illness despite reassurance. Its pathological manifestation can be diagnosed as hypochondriacal or illness anxiety or somatic symptom disorder. Health anxiety is associated with psychological distress and adverse life events, among others, and leads to considerable economic burden. Compared to the majority population, migrants, and ethnic minorities often face major health inequalities. Several mental illnesses and psychosomatic complaints are more common among these groups. To date, potential ethnic and migration-related inequalities in health anxiety have not been clearly described. However, they are of high relevance for the provision of adequate health care of this diverse and potentially vulnerable group. Thus, we conducted a systematic review and meta-analysis of health anxiety in migrants and ethnic minorities.

Methods

A systematic literature search of PubMED, Web of Science, PsycINFO, and PSYNDEX was conducted, covering all studies published until 1st of December 2021. Studies were selected if they employed validated measurement tools of health anxiety and examined migrants and/or ethnic minorities in comparison with the majority population. Meta-analytic methods were applied by using a random-effect model. The study quality was assessed with the Effective Public Health Practice Project Quality Assessment Tool (EPHPP).

Results

We identified 18 studies from 445 studies initially screened. Of these, 14 studies conducted in North America with a total number of 5,082 study participants were included in the meta-analysis. The pooled effect size indicated a higher risk of health anxiety in migrants and ethnic minorities compared to the majority population (OR 1.39, 95%-CI 1.01-1.92). The results proved not to be robust according to publication bias (adjusted OR 1.18, 95%-CI 0.83-1.69) and fail-safe N (2/3 < benchmark N = 75) and are limited due to heterogeneity (I 2 = 57%), small sample sizes and an overall low quality of included studies.

Conclusion

To address the diversity of migrants and ethnic minorities, inter-sectional approaches across different countries are needed in research to shed further light on social inequalities in health anxiety linked to migration.

Family Dysfunction and Cyberchondria among Chinese Adolescents: A Moderated Mediation Model

Cyberchondria has become a severe health problem and a significant public concern. In addition to the impacts that cyberchondria involves, individual psychological and behavioral factors have been identified. However, the role of family function and the mediating and moderating mechanisms underlying these relations are not understood well, especially among adolescents. Based on family functioning and cognitive-behavioral theory, this study sought to examine whether family dysfunction was associated with cyberchondria, and a moderated mediation model was prepared as a means of exploring whether health anxiety was a mediator of relationships between family dysfunction and cyberchondria, as well as whether optimism moderated these mediating processes. A total of 2074 Chinese adolescents (mean = 15.08 years, SD = 1.79) reported their demographic information, family dysfunction, health anxiety, optimism, and cyberchondria. The findings showed that family dysfunction was positively related to cyberchondria. Moreover, health anxiety partially mediated the relationship between family dysfunction and cyberchondria. Finally, optimism moderated the interplay among health anxiety and cyberchondria. Consistent with the expectancy-value models, this positive relationship was weaker for adolescents with a higher level of optimism. These results suggest that it is vital to simultaneously consider individual and family factors as a means of understanding adolescent cyberchondria when performing cyberchondria intervention programs.

A preliminary investigation of Cyberchondria and its correlates in a clinical sample of patients with obsessive-compulsive disorder, anxiety and depressive disorders attending a tertiary psychiatric clinic

Objectives. This cross-sectional study aimed to investigate the frequency and presentation of cyberchondria (CYB) in patients with obsessive-compulsive disorder (OCD), anxiety disorders (ADs), and major depression disorder (MDD).Methods. Seventy-seven patients (OCD:25, ADs:26, MDD:26) referred to a tertiary psychiatry outpatient clinic and 27 healthy controls (HCs) were included. A 'working' definition of CYB was used to measure CYB frequency. CYB severity was measured with the Cyberchondria Severity Scale (CSS).Results. CYB as currently defined was present in just 1.3% of the combined patients' sample. Using a broader definition (omitting the disability criterion), we found a higher distribution (OCD:12%, ADs:19.2%, MDD:15.4%, HCs:3.7%) and greater CYB symptom severity. Patients with OCD (63.3 ± 18.9) and ADs (63.3 ± 25.9) showed a higher CYB severity, compared with HCs (48.4 ± 9.9, p<.05). In the combined patients' sample, a positive correlation was found between the CSS scores and measures of health anxiety or hypochondriasis. Higher CYB symptom severity emerged in patients with a positive family history of psychiatric disorders and in those prescribed benzodiazepines or mood-stabilisers.Conclusion. CYB represents a common transdiagnostic syndrome in patients with OCD, ADs, and MDD with a spectrum of severity and indicates a variable burden of illness, supporting the need for specific clinical considerations and interventions.Key pointsCyberchondria (CYB) represents a common transdiagnostic syndrome in patients with obsessive-compulsive disorder, anxiety, and depressive disorders.CYB's frequency as a syndrome of compulsive online health searches associated with an increased anxiety and distress was reported in 10-20% patients.Health anxiety/hypochondriasis showed a strong correlation with CYB.Patients with a positive family history of psychiatric disorders and those prescribed benzodiazepines or mood-stabilisers showed higher CYB symptom severity.Considering the spread of Internet use for health-related information, additional studies investigating CYB in clinical samples are encouraged.

The Development of Illness Anxiety Disorder in a Patient After Partial Thyroidectomy

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), characterises illness anxiety disorder (IAD) as the preoccupation with having or acquiring a serious illness in the absence of somatic symptoms (or, if present, symptoms that are only mild in severity). DSM-5 includes illness anxiety disorder in the category called somatic symptom and related disorders, characterised by prominent somatic concerns, distress, and impaired functioning. More often than in psychiatric settings, individuals with illness anxiety disorder are encountered in primary care and specialist medical settings. Despite negative laboratory results, the benign course of the alleged disease over time, and adequate reassurances from specialists, their conviction of being ill persists. Illness anxiety preoccupations are heterogeneous, and the degree of insight is variable. Their illness-related preoccupation interferes with their relationships with family, friends, and coworkers. They are frequently addicted to internet searches about their feared illness, inferring the worst from the information (or false information) they uncover. Patients with illness anxiety disorder often have comorbid psychopathology, especially anxiety and depressive disorders. Typically, illness anxiety disorder is chronic. Physical symptoms are absent or mild and frequently represent a misinterpretation of normal bodily sensations. This case report presents the case of a patient diagnosed with IAD by a psychiatrist. The patient had been seen by his primary care physician and therapist for three years without any improvement in his symptoms before he was referred to a psychiatrist. After undergoing a partial thyroidectomy in 2018, this patient has been experiencing increasing symptoms of recurrent anxiety/fear consistent with IAD, despite extensive medical examinations that have consistently revealed normal results.

Prevalence of DSM-5 somatic symptom disorder in Chinese patients with breast cancer

OBJECTIVE

The aims of this study were to explore the frequency of somatic symptom disorder (SSD) and the relationship between SSD and somatic, psychological, and social factors in Chinese patients with breast cancer.

METHODS

This multicenter cross-sectional study enrolled 264 patients with breast cancer from 3 different departments in Beijing. The structured clinical interview for DSM-5 (SCID-5) for SSD. Standardized questionnaires and clinical data were used to compare patients with and without SSD.

RESULTS

SSD was diagnosed in 21.6% (57/264) of all enrolled patients. No differences were found between SSD patients and non-SSD patients in terms of sociodemographic characteristics and tumor-specific variables, except radiotherapy.However, patients with SSD reported higher levels of depression, anxiety and cancer-related worry. They also showed a longer duration of symptoms, greater impairment in daily life, more concern over their physical complaints and more doctor visits. In a stepwise binary logistic regression analysis, among others, higher health anxiety (WI-8, Exp(B) = 0.107, p = 0.009) and more doctor visits (OR = -1.841, p < 0.001) showed a significant association with SSD; the model explained 53.7% of the variance.

CONCLUSIONS

Similar to other physical diseases, there is a high prevalence of SSD in patients with breast cancer. SSD patients differ from non-SSD patients by exhibiting higher cancer-related emotional distress and dysfunctional illness perception and behavior. There remain substantial challenges in the diagnosis of SSD in patients with cancer and other medical conditions. This article is protected by copyright. All rights reserved.

Somatic symptom disorder: a scoping review on the empirical evidence of a new diagnosis

BACKGROUND

In 2013, the diagnosis of somatic symptom disorder (SSD) was introduced into the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). This review aims to comprehensively synthesize contemporary evidence related to SSD.

METHODS

A scoping review was conducted using PubMed, PsycINFO, and Cochrane Library. The main inclusion criteria were SSD and publication in the English language between 01/2009 and 05/2020. Systematic search terms also included subheadings for the DSM-5 text sections; i.e., diagnostic features, prevalence, development and course, risk and prognostic factors, culture, gender, suicide risk, functional consequences, differential diagnosis, and comorbidity.

RESULTS

Eight hundred and eighty-two articles were identified, of which 59 full texts were included for analysis. Empirical evidence supports the reliability, validity, and clinical utility of SSD diagnostic criteria, but the further specification of the psychological SSD B-criteria criteria seems necessary. General population studies using self-report questionnaires reported mean frequencies for SSD of 12.9% [95% confidence interval (CI) 12.5-13.3%], while prevalence studies based on criterion standard interviews are lacking. SSD was associated with increased functional impairment, decreased quality of life, and high comorbidity with anxiety and depressive disorders. Relevant research gaps remain regarding developmental aspects, risk and prognostic factors, suicide risk as well as culture- and gender-associated issues.

CONCLUSIONS

Strengths of the SSD diagnosis are its good reliability, validity, and clinical utility, which substantially improved on its predecessors. SSD characterizes a specific patient population that is significantly impaired both physically and psychologically. However, substantial research gaps exist, e.g., regarding SSD prevalence assessed with criterion standard diagnostic interviews.

The Scope of Metacognitive Therapy in the Treatment of Psychiatric Disorders

Metacognitive therapy (MCT) is a novel and promising transdiagnostic psychotherapy intervention based on the Self-Regulatory Executive Function model of conceptualizing emotional disorders. It was developed by Adrian Wells in 2009. Its therapeutic response occurs by reducing dysfunctional metacognitive beliefs regarding worry and rumination, often seen in patients with psychiatric disorders. Since its inception, it has been increasingly applied to a wide spectrum of psychiatric illnesses, but mainly focusing on mood and anxiety disorders. To our knowledge, no study has detailed its existing therapeutic scope in psychiatry. In this comprehensive narrative review, we describe the various psychiatric illnesses in which MCT has been used, the advantages of MCT, and the limitations of the MCT research. In addition, we propose some solutions to systematically examine its place in psychiatry. We encountered its potential role in treating trauma and stress-related disorders, obsessive-compulsive spectrum disorders, personality disorders, psychotic disorders, substance use disorders, and sexual disorders.

Social inequalities in health anxiety: A systematic review and meta-analysis

OBJECTIVE

The association between a low socioeconomic status and poor health, also known as social inequalities in health, has been shown in numerous studies. This also applies to most mental illnesses, such as somatization or anxiety disorders. It is unclear, however, whether social inequalities are evident in health anxiety as well. Therefore, this review and meta-analysis systematically examines social inequalities in health anxiety.

METHODS

A systematic literature search was conducted covering all studies published until August 2021. The databases PubMED, Web of Science, PsycINFO, and PSYNDEX were screened to identify quantitative studies using validated tools to measure health anxiety and examining the association with socioeconomic status. Meta-analytic methods were applied by using random-effect models. The study quality was assessed with the Effective Public Health Practice Project Quality Assessment Tool.

RESULTS

Overall, 37 studies were eligible for meta-analysis. Effect sizes of 27 studies using screening scales and 10 studies using diagnostic interviews to measure health anxiety were calculated separately. Meta-analyses revealed a significant association between socioeconomic status and health anxiety (r - 0.14, 95%-CI -0.18 to -0.09 (screening scales) and OR 0.63, 95%-CI 0.43 to 0.92 (diagnostic interviews)), indicating a lower risk for health anxiety in people with higher socioeconomic status.

CONCLUSION

Findings suggest that the health-related disadvantage of socially deprived people is also evident regarding health anxiety. This should be considered in programs to reduce social inequalities in health. PROSPERO registration number CRD42021237550.

Managing rumination and worry: A pilot study of an internet intervention targeting repetitive negative thinking in Australian adults

BACKGROUND

Rumination and worry, both forms of repetitive negative thinking (RNT), have been implicated in the onset, maintenance, severity, and relapse risk of depression and anxiety disorders. Despite promising initial findings for internet-delivered interventions targeting both rumination and worry simultaneously, no studies have investigated treatment effects in an adult population or when delivered in a brief, unguided format. We developed a 3-lesson unguided online treatment program targeting both rumination and worry and evaluated the adherence and effectiveness in Australian adults using an open pilot trial.

METHODS

Adult participants (N=26) experiencing elevated levels of RNT completed the online program over 6-weeks. Outcomes were assessed at baseline, post-treatment, and 1-month follow-up. Intention-to-treat linear mixed models were used to examine effects on RNT, anxiety, depression, and general psychological distress.

RESULTS

Of the 26 participants who started the program, 18 completed all three lessons (69.2% completion rate). Large within-subject effect sizes were found between pre- and post-treatment for RNT (Hedges' g= 2.26) and symptoms of depression (g = 1.04), generalised anxiety (g = 1.82) and distress (g = 0.93). Treatment effects were maintained at 1-month follow-up.

LIMITATIONS

No long-term follow-up, exclusion of severely depressed individuals.

CONCLUSIONS

This is the first study to evaluate a brief, unguided internet intervention targeting both rumination and worry in adults. The results provide promising preliminary evidence for the feasibility and acceptability of the online program. Randomised controlled trials are needed to evaluate treatment efficacy compared to a control group and to investigate long-term outcomes.

Persistence rate of DSM-5 somatic symptom disorder: 4-year follow-up in patients from a psychosomatic outpatient clinic

BACKGROUND

Somatic Symptom and Related Disorders (SSD) were introduced by DSM-5 in order to improve the classification of somatoform disorders. There is a lack of longitudinal studies on course and predictors of SSD. The present study investigates the natural course of SSD in a four-year follow-up study in patients from a psychosomatic outpatient clinic.

MATERIAL AND METHODS

At baseline, n = 360 outpatients completed a semi-structured clinical interview to assess SSD, and additional self-report questionnaires (SSS-8, SSD-12, PHQ-8, GAD-7, SF-12). 112 patients were re-assessed after four years. Persistence rate and predictors for persisting SSD were evaluated.

RESULTS

The prevalence rate of SSD at baseline was 51.8%, and 47.3% at follow-up. We found a persisting SSD in 30.4% (n = 34) of the patients, a remission rate of 21.4% (n = 24) and an incidence rate of 16.9% (n = 19). 31.3% (n = 35) of the sample never received a SSD diagnosis. Significant predictors for persistence were a high psychological burden through somatic symptoms (OR: 1.13, 95% CI: 1.01-1.26) and general anxiety (OR: 1.38, 95% CI: 1.01-1.88) at baseline.

CONCLUSION

This study indicates that SSD is highly prevalent and persistent in patients from a psychosomatic setting. Our findings indicate that psychological and behavioral factors contribute to the maintenance of SSD and present potential targets for interventions. Future interventions for SSD could potentially be optimized by addressing psychological processes such as catastrophic thinking styles and symptom focusing.

Clinical and psychobehavioral features of outpatients with somatic symptom disorder in otorhinolaryngology clinics

OBJECTIVE

In the Otorhinolaryngology Department, patients exhibiting somatic symptoms without a medical cause are frequently neglected and left untreated. The aim of this study was to characterize the psychosomatic features of outpatients with somatic symptom disorder (SSD) to better identify patients needing treatment.

METHODS

This cross-sectional study enrolled 883 consecutive patients with medically unexplained symptoms. A semistructured clinical interview was employed to confirm the diagnosis of SSD. Data, including sociodemographic and clinical measures, were collected. The Patient Health Questionnaire-15 (PHQ-15) and Somatic Symptom Scale-China (SSS-CN) were used to assess the severity of somatic symptoms; the Patient Health Questionnaire-9 (PHQ-9) was used to assess depression; the General Anxiety Disorder-7 (GAD-7) was used to assess anxiety; and the 12-item Short-form Health Survey (SF-12) was used to assess quality of life (QoL).

RESULTS

Based on the DSM-5 criteria, 641 patients were placed in the SSD group, and 212 were placed in the normal group. Compared with the normal group, the SSD group had significantly more doctor visits, longer symptom durations, higher GAD-7 and PHQ-9 scores, and lower physical composite scores (PCSs) and mental composite scores (MCSs). Spearman's correlation analysis and multiple linear regression analyses showed that the SSS-CN score, PHQ-15 score and the patient's subjective feeling that his or her daily life was affected by the disorder were significant risk factors for low PCSs; the SSS-CN, PHQ-15, PHQ-9, and GAD-7 scores were independent risk factors for low MCSs.

CONCLUSION

Our findings demonstrated that SSD patients are not rare in otorhinolaryngology clinics in China and that their QoL is significantly affected by SSD. Otolaryngologists should thoroughly evaluate these patients from the perspective of psychosomatic medicine.

Psychometric Evaluation of the Whiteley Index-8 in Chinese Outpatients in General Hospitals

Background: Excessive and persistent health anxiety is a common and disabling but often unrecognized illness. Therefore, screening patients for health anxiety is recommended in primary care. The aim of the present study was to examine the psychometric properties of an updated version of the eight-item Whiteley Index (WI-8) among outpatients in general hospitals in China. Methods: The presented data were derived from a multicenter cross-sectional study. The Chinese version of the WI-8 was administered to a total of 696 outpatients. Cronbach's alpha was used to evaluate the internal consistency of the scale. The validity of the scale was evaluated based on factor analysis and correlation analyses. To assess the discriminant ability, receiver operating characteristic (ROC) analysis was conducted. Results: Cronbach's alpha was 0.937, and it decreased (0.925) after deleting the new 8th item. Factor analysis extracted one factor accounting for 69.2% of the variance. Moderate correlations were found (0.414-0.662) between the WI-8 and General Anxiety Disorder (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Patient Health Questionnaire-15 (PHQ-15) and Somatic Symptom Disorder B-criteria (SSD-12). The ROC curve indicated excellent discriminatory ability to discriminate among patients with health anxiety (AUC = 0.822). Conclusions: The new WI-8 version is a reliable and valid tool to screen for health anxiety in general hospital patients. We recommend the WI-8 as a useful screening tool for health anxiety.
