The outcome of health anxiety in primary care. A two-year follow-up study on health care costs and self-rated health

Mental burden of ocular surface discomfort

OBJECTIVE

This research investigates the associations between Dry Eye Disease (DED), pain perception, and mental health, focusing on how neuropathic pain influences treatment efficacy and patients' quality of life.

METHODS AND RESULTS

The study delves into the complexity of DED by assessing the correlation between ocular pain, depression, PTSD, and systemic pain conditions. It highlights the role of chronic neuropathic pain in DED and the nociceptive hypothesis, which suggests that psychological stress can exacerbate DED symptoms. Additionally, it explores diagnostic and management strategies for DED, emphasizing the importance of considering psychological aspects to improve patient care.

CONCLUSIONS

The intricate nature of DED, closely linked to mental health issues, requires a comprehensive diagnostic and therapeutic approach. Addressing neuropathic pain and psychological factors is crucial for effective DED management. Future efforts should focus on developing specific interventions targeting DED's physical and emotional impacts to enhance overall patient well-being.

Health anxiety in cancer patients, assessed with the Whiteley Index

OBJECTIVE

Health anxiety (HA) is frequently observed in patients suffering from a severe disease such as cancer. This study aimed to test the psychometric properties of the Whiteley Index-7 (WI-7) measuring HA and to identify prognostic factors for heightened HA in cancer patients.

METHODS

A sample of 1723 cancer patients, treated in a German rehabilitation clinic, completed the Whiteley Index-7, the Generalized Anxiety Disorder screener GAD-7, the Patient Health Questionnaire PHQ-9, the Fear of Progression questionnaire FoP-Q-12, the Concerns About Cancer Recurrence questionnaire CARQ-4, and two subscales of the EORTC QLQ-SURV100.

RESULTS

The internal consistency of the WI-7 was good (Cronbach's α = 0.85), and the correlations between the WI-7 and other scales were as follows: 0.64 (GAD-7), 0.63 (PHQ-9), 0.75 (FoP-Q-12), 0.71 (CARQ-4), 0.66 (SURV-HD), and 0.75 (SURV-NHO). Women showed markedly higher levels of HA than men (effect size: d = 0.40), and patients aged 60 years and above reported lower levels of HA than younger patients (d = -0.32). Melanoma patients showed the highest HA mean score (M = 10.9), and patients receiving antibody therapy showed heightened levels of HA (M = 10.7). When considering age and sex, the effects of tumor type and treatment become smaller than in the univariate analyses.

CONCLUSION

The WI-7 is a suitable instrument for assessing HA in cancer patients. When evaluating the effects of cancer type or treatment on HA, one has to take into account the age and sex distribution. Younger patients and women deserve special attention regarding HA.

[Health anxiety: Another epidemic to prepare for]

Health anxiety (HA) is a frequent problem (up to 20% of consultants in the context of secondary care) responsible for decreased well-being, disability, somatic and psychiatric complications, which contributes to high healthcare expenditures at the population level. It is likely, if not definitely established, that the prevalence of ACS is increasing, and this can partly be explained by the growing medicalization of society in general, the appetite of Media for health issues, and the uncontrolled use of the Internet (which can lead certain vulnerable subjects to cyberchondria). The pandemic of COVID-19 could have contributed to it, at least by the significant increase in the overall level of psychological distress in the population it has caused, although this has not formally been demonstrated to date. The diagnosis of ACS is easy, as soon as its assessment is considered as a mandatory part of any medical consultation. Certain intuitive attitudes of doctors, such as reassurance, prove to be iatrogenic for the patient with HA. The management of HA can be facilitated by an acculturation of physicians to cognitive conceptions of anxiety in general and HA in particular. HA is effectively treatable by certain psychotherapy and in the first place cognitive and behavioral therapies (CBT), but the availability of trained therapists and accessible at a lower cost is sorely lacking, particularly in France.

The Relation of Health Anxiety to Treatment Utilization Among Patients with Substance Use Disorders: The Moderating Role of Racial/Ethnic Background

Background: Although health anxiety is broadly related to the overutilization of healthcare, limited research has examined this relation among individuals with substance use disorders (SUDs), or the extent to which racial/ethnic differences influence this relationship. Objectives: The purpose of the current study is to examine the moderating role of racial/ethnic minoritized background in the relationship between health anxiety and treatment utilization among individuals with SUDs. In the present study, patients with SUDs receiving residential treatment in Mississippi (N=118; 62% racial/ethnic minoritized status, 35.6% White) completed a measure of health anxiety and answered questions about past mental health, physical health, and substance use treatment. Regression models examined whether racial/ethnic minoritized status (White vs. racial/ethnic minoritized status) moderated the relation of health anxiety to treatment utilization among patients with SUDs. Treatment utilization was examined by asking whether participants had seen a doctor or mental health provider, engaged in substance use treatment, or alcohol treatment prior to their current treatment (dichotomous), as well as the number of times they had engaged in each treatment (physical health, mental health, substance use, and alcohol treatment) in the past year (continuous). Results: Results revealed that the facets of health anxiety involving concerns about pain and disease phobia were positively associated with treatment utilization, but only among racial/ethnic minoritized participants, with concerns about pain positively associated with self-reported physical health treatment utilization (OR=0.70, 95% CI=0.50; 0.97) and disease phobia positively associated with past mental health (B = 0.36, p = 0.023) and alcohol use treatment (B=-0.23, p=.009). Conversely, disease phobia was related to less prior alcohol use treatment among White participants (B=-0.23, p=.009). Conclusions: Overall, among patients in residential treatment for SUDs, racial/ethnic minoritized participants with SUDs reported more health anxiety compared to white participants, and certain facets of health anxiety (i.e., concerns about pain and worry about severe illness) were linked to heightened treatment utilization among racial/ethnic minoritized individuals.

Further Evidence for a Dimensional Latent Structure of Health Anxiety: Taxometric Analyses of the Whiteley Index Based on Two German Representative Samples

Health anxiety is an intricate part of illness anxiety and somatic symptom disorder. Based on convenience samples, two out of three available studies indicate that it is a dimensional rather than a categorical construct. Using two representative datasets, this study investigates whether previous results can be clarified. Conventional taxometric analyses as well as comparison curve fit indices (CCFI) profile analyses (MAMBAC and MAXSLOPE procedures) were calculated with two datasets of the German adult population assessing the Whiteley Index (WI-14, N = 2,072; WI-7, N = 2,498). Mean CCFIs indicated a dimensional structure for both the WI-7 (mean CCFI = 0.42, mean CCFI profile = 0.40) and the WI-14 (mean CCFI = 0.44, mean CCFI profile = 0.32). The results support and extend previous findings by strongly suggesting a dimensional distribution of health anxiety in the general population. Implications for research and practice comprise the adoption of a dimensional description of psychopathology as well as transdiagnostic treatment approaches.

Mechanistic studies in pathological health anxiety: A systematic review and emerging conceptual framework

BACKGROUND

Pathological health anxiety (PHA) (e.g., hypochondriasis and illness anxiety disorder) is common in medical settings and associated with increased healthcare costs. However, the psychological and neurobiological mechanisms contributing to the development and maintenance of PHA are incompletely understood.

METHODS

We performed a systematic review to characterize the mechanistic understanding of PHA. PubMed, PsycINFO, and Embase databases were searched to find articles published between 1/1/1990 and 12/31/2022 employing a behavioral task and/or physiological measures in individuals with hypochondriasis, illness anxiety disorder, and PHA more broadly.

RESULTS

Out of 9141 records identified, fifty-seven met inclusion criteria. Article quality varied substantially across studies, and was overall inadequate. Cognitive, behavioral, and affective findings implicated in PHA included health-related attentional and memory recall biases, a narrow health concept, threat confirming thought patterns, use of safety-seeking behaviors, and biased explicit and implicit affective processing of health-related information among other observations. There is initial evidence supporting a potential overestimation of interoceptive stimuli in those with PHA. Neuroendocrine, electrophysiology, and brain imaging research in PHA are particularly in their early stages.

LIMITATIONS

Included articles evaluated PHA categorically, suggesting that sub-threshold and dimensional health anxiety considerations are not contextualized.

CONCLUSIONS

Within an integrated cognitive-behavioral-affective and predictive processing formulation, we theorize that sub-optimal illness and health concepts, altered interoceptive modeling, biased illness-based predictions and attention, and aberrant prediction error learning are mechanisms relevant to PHA requiring more research. Comprehensively investigating the pathophysiology of PHA offers the potential to identify adjunctive diagnostic biomarkers and catalyze new biologically-informed treatments.

Factors associated with public and private healthcare utilization for outpatient care among older adults in India: A Wagstaff's decomposition of Anderson's behavioural model

In India, an expanding ageing population will become a public health alarm, putting additional pressure on the healthcare system. Therefore, the current study aimed to examine the factors associated with outpatient healthcare choices among older Indian adults. We used data from the first wave of the Longitudinal Ageing Study in India (LASI, 2017-2018). A total of 34,588 individuals (age 45 years and over) who accessed outpatient healthcare services in the last 12 months during the survey were included in this research. A bivariate chi-square test was used to present the percentage distribution of types of outpatient healthcare utilisation by background characteristics. Multinomial logistic regression and Wagstaff's decomposition analyses were employed to explore the interplay of outpatient healthcare utilisation and allied predisposing, enabling, and need factors and examine these factors' contributions to the wealth-based inequalities in public, private, and other healthcare utilisation. Outpatient healthcare utilisation varied significantly according to socioeconomic and demographic factors. The findings suggest that consumption quintiles, place of residence, education, and health insurance were significant determinants of private and public healthcare utilisation and contributed to wealth-based inequalities in healthcare choices. The current study emphasises the need to strengthen and promote public healthcare services.

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.

Exploring the interplay between psychotic experiences, functional somatic symptoms and health anxiety in childhood and adolescence - A longitudinal cohort study

BACKGROUND

Similarities exist between contemporary explanatory models underlying psychosis development, functional somatic symptoms, and health anxiety. The current study aimed to examine the potential interplay between psychotic experiences (and alternate measures of anomalous self-experiences and aberrant attribution of salience) and functional somatic symptoms on the outcome of health anxiety in youths.

METHODS

In a prospective general-population birth cohort, the Copenhagen Child Cohort 2000 (CCC2000), data from two time-points were available for 1122 individuals. We assessed the associations between psychotic experiences and functional somatic symptoms with health anxiety both cross-sectionally at ages 11- and 16-years, and longitudinally from age 11 to 16. Further, we examined if there was an interaction between these two domains on the outcome of health anxiety using the interaction contrast ratio.

RESULTS

Functional somatic symptoms and psychotic experiences were strongly cross-sectionally associated with health anxiety at both ages 11 and 16, even after adjustment for general psychopathology. In the longitudinal analyses, functional somatic symptoms, and psychotic experiences at age 11 were not individually associated with health anxiety at age 16 but having both functional somatic symptoms and psychotic experiences was: odds ratio 3.90, 95%CI 1.7-8.9, with suggestion of evidence for interaction beyond the additive effects. This association was attenuated after adjustment for general psychopathology: odds ratio 2.6, 95 % CI 1.0-6.4.

CONCLUSION

The strong associations between the domains support the idea of possible overlapping mechanisms underlying psychotic experiences, functional somatic symptoms, and health anxiety.

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.

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.

Who uses food barcode scanner apps and why? Exploration of users' characteristics and development of the Food Barcode Scanner App Questionnaire

BACKGROUND

Food barcode scanner apps (FBSAs) are increasingly being used to verify food quality. By scanning a product's barcode, they can provide a range of information, including nutritional quality or information on the toxicity of food components. Although they seem to be widely used, no study has yet examined their use in the general population. The objectives of this study were therefore twofold: (a) to identify who the users of FBSA are and (b) to evaluate behaviours and cognitions associated with use of these apps through the development and validation of the Food Barcode Scanner App Questionnaire (FBSAQ).

METHOD

A total of 1626 women (average age of 37.51 years; SD = 12.67) from the general population were included in this study, with 25.7% reporting themselves as using at least one FBSA. Participants completed questionnaires assessing socio-demographic and health characteristics, the use of health apps and the FBSAQ, when relevant.

RESULTS

The users of FBSAs did not differ from nonusers in regard to key socio-demographic characteristics, but they were more likely to use healthcare services and other health apps than nonusers of FBSAs. Psychometric analyses allowed validation of the FBSAQ through three factors: pathological use, dietary concerns and exclusion of unhealthy components.

CONCLUSION

Data showed that the use of FBSAs can be beneficial for many individuals, as they help with food choices. However, some user may develop more problematic behaviours and have difficulties in not using these apps.

Brief digital self-care intervention for health anxiety in a Swedish Medical University Clinic: a prospective single-group feasibility study

OBJECTIVES

In routine psychiatric care in Stockholm, Sweden, a comprehensive therapist-guided intervention for clinically significant health anxiety is implemented. However, there is a need for more easily accessible self-care interventions to improve treatment dissemination. This study aimed to transform an existing therapist-guided digital intervention into a self-care intervention, reducing patient burden and used clinical resources while maintaining quality and safety.

DESIGN

An uncontrolled feasibility study.

SETTING

Conducted at Karolinska Institutet, a medical university in Sweden, with nationwide recruitment trough online advertisements.

PARTICIPANTS

Twenty-five adults used the self-care intervention and underwent telephone assessments, along with completing self-rated questionnaires.

INTERVENTION

The newly developed 8-week self-care intervention was designed to be user-friendly without therapist guidance, and to facilitate high levels of behavioural engagement.

PRIMARY AND SECONDARY OUTCOME MEASURES

Indicators of quality and safety, including changes in health anxiety severity (primary), clinician time, participant adherence, perceived credibility/satisfaction with the intervention and adverse events, were benchmarked against a previous study of the more comprehensive intervention it was based on.

RESULTS

Compared with the original guided intervention, the self-care intervention was condensed in terms of text (up to 70% less reading), duration (8 weeks instead of 12) and number of exercises. Quality indicators were similar to the original version. Most participants worked actively with core components in the self-care intervention. Within-group effects on health anxiety from pretreatment to the 3-month follow-up were large (g=1.37; 95% CI 0.74 to 2.00). No serious adverse events were reported.

CONCLUSIONS

This brief digital self-care intervention shows potential for increasing access to treatment for individuals with health anxiety while reducing the burden on patients and clinical resources. Future studies should investigate the optimal type of intervention and support for different individuals, and if non-inferiority can be established.

The global economic burden of health anxiety/hypochondriasis- a systematic review

BACKGROUND

Recent studies have shown a lifetime prevalence of 5.7% for health anxiety/hypochondriasis resulting in increased healthcare service utilisation and disability as consequences. To the best of our knowledge, there has been no systematic review examining the global costs of hypochondriasis, encompassing both direct and indirect costs. Our objective was to synthesize the available evidence on the economic burden of health anxiety and hypochondriasis to identify research gaps and provide guidance and insights for policymakers and future research.

METHODS

A systematic literature search was conducted using PubMed, Web of Science, PsycInfo, EconLit, IBSS and Google Scholar without any time limit, up until April 2022. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed in this search and the following article selection process. The included studies were systematically analysed and summarized using a predefined data extraction sheet.

RESULTS

Of the 3044 articles identified; 10 publications met our inclusion criteria. The results displayed significant variance in the overall costs listed among the studies. The reported economic burden of hypochondriasis ranged from 857.19 to 21137.55 US$ per capita per year. Most of the investigated costs were direct costs, whereas the assessment of indirect costs was strongly underrepresented.

CONCLUSION

This systematic review suggests that existing studies underestimate the costs of hypochondriasis due to missing information on indirect costs. Furthermore, there is no uniform data collection of the costs and definition of the disease, so that the few existing data are not comparable and difficult to evaluate. There is a need for standardised data collection and definition of hypochondriasis in future studies to identify major cost drivers as potential target point for interventions.

Examining associations between early adverse life events and health anxiety using the DanFund study

Childhood adverse life events, in particular illness-related events, have been proposed as a risk factor for development of health anxiety.

OBJECTIVE

To examine: 1) The association between accumulated early adverse life events and health anxiety in adulthood and 2) The influence of specific types of life events, i.e., illness, injury, loss, and the impact of their exposure time on health anxiety in adulthood.

METHOD

A population-based, cross-sectional study including 7454 participants from the Danish study of Functional Disorders (DanFunD). Health anxiety was assessed with Whiteley-6-R and early adverse life events with the Cumulative Lifetime Adversity Measure. Caseness was defined as a Whiteley-6-R score ≥ 90%ile. Generalised linear models were used to estimate the association with relative risk (RRa, adjusted for sociodemographics).

RESULTS

A cumulative effect was found for each additional adverse life event with 8.03% increased risk of health anxiety. Two categories were associated with a higher risk: violence (RRa = 1.65, 95% CI: 1.37-1.99, P < 0.001) and relationship stress (RRa = 1.34; 95% CI: 1.15-1.57, P < 0.001). Respondents with self-reported childhood illness were also more likely to report health anxiety (RRa = 1.52, 95% CI 1.11-2.09, P = 0.009). Timewise, health anxiety seemed associated with illness during school age and injury during adolescence.

CONCLUSIONS

Accumulated adverse life events, early exposure to specific categories and specific health-related life events were associated with self-reported health anxiety in adulthood. Our findings provide new knowledge on the potential role of early life events in health anxiety which could inform early intervention.

The short-form of the Cyberchondria Severity Scale (CSS-12): Adaptation and validation of the Spanish version in young Peruvian students

BACKGROUND

Cyberchondria is defined as the increase in health-related anxiety or anguish associated with excessive or repeated online searches for health-related information. Our objective was to cross-culturally adapt and validate the CSS-12 scale for Peruvian Spanish speakers, to determine whether the Bifactor model works as well in our population as in previous studies' and to explore whether the Bifactor-ESEM is a more suitable model.

METHODS

We performed a cultural adaptation using the Delphi method and a validation study on medical students between 2018 and 2019. Reliability was evaluated by using Cronbach's alpha (α) and McDonald's omega (Ω) for internal consistency, and Pearson's r and intraclass correlation coefficient (ICC), for test-retest reliability. We evaluated construct validity by contrasting four measurement models for the CSS-12 and the convergent validity against health anxiety.

RESULTS

The Spanish CSS-12 showed excellent reliability (α = .93; Ω = .93; ICC = .93; r = .96). The Bifactor ESEM model showed the best fit, supporting a unidimensional measure of the general cyberchondria. This measure was positively associated with health anxiety (r = .51).

CONCLUSIONS

The Spanish CSS-12 provides a valid and reliable unidimensional measure of cyberchondria, which is distinguishable from the more general health anxiety. This can be applied to similar populations and future research. The Bifactor-ESEM model appears to offer a more accurate and realistic representation of the multifaceted nature of cyberchondria. We provide a free-to-use form of the Spanish CSS-12 as supplemental material.

Healthcare use and fear of recurrence in adult cancer survivors at 2.5 years after a cancer diagnosis: a nationwide register study in Denmark

PURPOSE

To investigate the association between fear of cancer recurrence (FCR) and healthcare use in general practice among cancer survivors.

METHODS

We linked nationwide register data to survey data on FCR in cancer survivors at 2.5 years after a cancer diagnosis. Multiple regression models were used to analyse the association between high FCR level and quartiles of healthcare use at 18-30 months before the cancer diagnosis (habitual healthcare use) and between high FCR level and healthcare use at 18-30 months after the cancer diagnosis (survivorship healthcare use).

RESULTS

We included 1538 cancer survivors in the study. High habitual healthcare use was associated with a high level of FCR (odds ratio = 2.07 (95% confidence interval (CI): 1.36-3.15)) for the 4th quartile of healthcare use compared to the 1st quartile. A high FCR score was also associated with higher healthcare use during cancer survivorship (incidence rate ratio (IRR) = 1.26 (95% CI: 1.14-1.40)). This association remained statistically significant when adjusting for habitual healthcare use (IRR = 1.20 (95% CI: 1.09-1.33)).

CONCLUSION

High healthcare use before the cancer diagnosis was associated with high FCR during survivorship. This indicates that FCR is partly explained by a general (pre-diagnostic) health concern. High FCR predicted high healthcare use during cancer survivorship, even when adjusting for habitual healthcare use.

IMPLICATIONS FOR CANCER SURVIVORS

Our results suggest that FCR in cancer survivors is triggered by a general high level of health concern, and the cancer diagnosis may further exacerbate this concern.

Health anxiety and associated constructs in school-age children and adolescents with congenital heart disease and their parents: A children's healthy-heart activity monitoring program in Saskatchewan cohort study

Youth with congenital heart disease (CHD) have been found to experience higher levels of health anxiety and associated constructs than typically developing peers. The association between youth and parent health anxiety has been explored in typically developing youth but this association remains unknown in youth with CHD. This association was explored using a prospective, cross-sectional study that included 36 school-age children and adolescents with CHD (median age =10.5 years, IQR = 4) and 35 parents (median age = 44 years, IQR = 10.5). Participants completed a demographic form and measures of health anxiety, anxiety sensitivity, intolerance of uncertainty, and anxiety disorder symptom categories (youth) or general anxiety (parent). Associations were observed between child and adolescent panic/agoraphobia symptoms and parent state anxiety (r = .41), child and adolescent intolerance of uncertainty and parent state and trait anxiety (r = .37; r = .46, respectively), and child and adolescent anxiety sensitivity and parent state anxiety (r = .40). No association was observed between health anxiety in children and adolescents and parents nor between child and adolescent health anxiety and parent associated constructs. For parents, associations between health anxiety and all measures of associated constructs of interest were observed. Study findings will facilitate improved understanding of the psychological needs of school-age children and adolescents with CHD.

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.

Hypochondriasis and self-medication among medical sciences students during the COVID-19 pandemic: A descriptive cross-sectional study in Northwestern Iran

BACKGROUND

Increased fear and anxiety among the general public following the emergence of coronavirus 2019 (COVID-19) can lead to hypochondriasis as well as indiscriminate use of drugs, versus the disease.

OBJECTIVE

The present study was conducted to identify the frequency and causes of self-medication and hypochondriasis among students.

METHODS

This descriptive cross-sectional study was conducted among 241 students of different disciplines of Khalkhal University of Medical Sciences in northwestern Iran over a period of six months. SPSS 26 software, Chi-square and Fisher tests were used to analyze the data.

RESULTS

The rate of self-medication was calculated 51%. The highest rate of self-medication was in the form of tablets (75.6%) and capsules (28.5%) and the highest type of medication was herbal medicine (59.3%) and multivitamins and complementary drugs (54.5%). The most common cause of self-medication was previous use and the effectiveness of the drug in the past (79.7%). The mean score of hypochondriasis was calculated at 21.52 (11.02) and the majority of students (49.8%) were in the healthy group. There was a statistically significant association between hypochondriasis and self-medication (p = 0.002).

CONCLUSION

Based on the findings, more than half of the participants in the study had self-medication. About 20% of students also experienced mild to moderate hypochondriasis. Therefore, it is suggested that the necessary training and support be provided to deal with the side effects of these two phenomena.

Symptom Perception in Pathological Illness Anxiety: Tactile Sensitivity and Bias

OBJECTIVE

Symptom perception in pathological illness anxiety (PIA) might be biased so that somatic signals are overreported. In the somatic signal detection task (SSDT), performance in detecting weak tactile stimuli gives information on overreporting or underreporting of stimuli. This task has not yet been applied in PIA.

METHODS

Participants with PIA (n = 44) and healthy controls (n = 40) underwent two versions of the SSDT in randomized order. In the original version, tactile and auxiliary light-emitting diode (LED) stimuli were each presented in half of the trials. In the adapted version, illness or neutral words were presented alongside tactile stimuli. Participants also conducted a heartbeat mental tracking task.

RESULTS

We found significantly higher sensitivity and a more liberal response bias in LED versus no-LED trials, but no significant differences between word types. An interaction effect showed a more pronounced increase of sensitivity from no LED to LED trials in participants with PIA when compared with the adapted SSDT and control group (F(1,76) = 5.34, p = .024, η2 = 0.066). Heartbeat perception scores did not differ between groups (BF01 of 3.63).

CONCLUSIONS

The increase in sensitivity from no LED to LED trials in participants with PIA suggests stronger multisensory integration. Low sensitivity in the adapted SSDT indicates that attentional resources were exhausted by processing word stimuli. Word effects on response bias might have carried over to the original SSDT when the word version was presented first, compromising group effects regarding bias.

Intolerance of uncertainty, anxiety sensitivity, and health anxiety during the COVID-19 pandemic: Exploring temporal relationships using cross-lag analysis

Intolerance of uncertainty (IU) and anxiety sensitivity (AS) have been widely discussed and explored as factors that may contribute to health anxiety. We propose that IU and AS are salient issues for many during the COVID-19 pandemic, and may play a role in the development or exacerbation of health anxiety during the pandemic. Studies have examined links between IU and AS with health anxiety during the pandemic, but these relationships have not been tested together using a longitudinal study design. In the present study, measures of IU, AS, and health anxiety were collected from 301 adults at two time points 6 months apart during (early stages of) the COVID-19 pandemic using an online survey platform. Cross-lagged analysis was utilized to simultaneously estimate cross-sectional and longitudinal associations between these three variables. Robust cross-sectional associations were observed, and IU prospectively predicted changes in both health anxiety and AS. No other statistically significant prospective associations emerged. Present findings support the putative role of IU in health anxiety, suggesting that some observed links between AS and health anxiety could be driven by shared variance with IU. IU may be an important factor to monitor and target in health anxiety interventions during the pandemic.

EFFECT OF HEALTH ANXIETY ON GLYCEMIC CONTROL IN PATIENTS WITH TYPE II DIABETES MELLITUS: A SINGLE CENTER, CROSS SECTIONAL STUDY

Context

Health anxiety was rarely investigated in Type II Diabetes Mellitus (T2DM).

Objectives

The present study examines the effect of health anxiety on glycemic control and evaluates factors associated with health anxiety in patients with T2DM according to HbA1c level.

Design

Cross-sectional.

Subjects and Methods

Socio Demographic Data Form (SDVF), Health Anxiety Inventory-Short Form(SHAI), The Hospital Anxiety and Depression Scale (HADS) were administered to 185 patients with Type II DM . Patients were divided into two groups according to HbA1 c level (HbA1c levels below 7 (Group 1, n=69) and above 7 (Group 2, n=185)). We analyzed prevalence of health anxiety, factors associated with health anxiety between poor and good glycemic control and evaluated of T2DM patients according to health anxiety scale scores.

Results

SHAI scale scores were low in 52 (28%), intermediate in 58 (31.2%) and high in 76 (40.8%) of the patients. We found the severity of depressive symptoms was positively correlated with health anxiety in both groups. As a result of this study, there was a relationship between high education and low socioeconomic level, having a job, exercise and anxiety level and low SHAI score in T2DM patients. Depression, stressful life events in the last 6 months were related with high health anxiety. Although the level of health anxiety was not different between groups, low blood sugar levels were related with high health anxiety.

Conclusions

This study found that the prevalence of health anxiety in T2DM patients was higher than expected irrespective to poor or good glycemic control, but level of health anxiety in patients with T2DM is not a good predictor for the HbA1c level.

The association between health anxiety, physical disease and cardiovascular risk factors in the general population – a cross-sectional analysis from the Tromsø study: Tromsø 7

Background

Health anxiety (HA) is defined as a worry of disease. An association between HA and mental illness has been reported, but few have looked at the association between HA and physical disease.

Objective

To examine the association between HA and number of diseases, different disease categories and cardiovascular risk factors in a large sample of the general population.

Methods

This study used cross-sectional data from 18,432 participants aged 40 years or older in the seventh survey of the Tromsø study. HA was measured using a revised version of the Whiteley Index-6 (WI-6-R). Participants reported previous and current status regarding a variety of different diseases. We performed exponential regression analyses looking at the independent variables 1) number of diseases, 2) disease category (cancer, cardiovascular disease, diabetes or kidney disease, respiratory disease, rheumatism, and migraine), and 3) cardiovascular risk factors (high blood pressure or use of cholesterol- or blood pressure lowering medication).

Results

Compared to the healthy reference group, number of diseases, different disease categories, and cardiovascular risk factors were consistently associated with higher HA scores. Most previous diseases were also significantly associated with increased HA score. People with current cancer, cardiovascular disease, and diabetes or kidney disease had the highest HA scores, being 109, 50, and 60% higher than the reference group, respectively.

Conclusion

In our general adult population, we found consistent associations between HA, as a continuous measure, and physical disease, all disease categories measured and cardiovascular risk factors.

The 14-item short health anxiety inventory (SHAI-14) used as a screening tool: appropriate interpretation and diagnostic accuracy of the Swedish version

BACKGROUND

The 14-item Short Health Anxiety Inventory (SHAI-14) is a common measure of health anxiety but its screening properties have not been studied. The aims of this study were to evaluate the SHAI-14 as a screening instrument, identify cut-offs for clinically significant health anxiety and investigate which scores correspond to different severity levels.

METHOD

The study included 1729 psychiatric patients and 85 healthy controls. Participants completed the SHAI-14 and underwent a diagnostic interview. Cut-off scores were evaluated in three scenarios to approximate screening 1) in a psychiatric clinic, 2) in a low prevalence setting and, 3) of healthy volunteers (cut-off for remission). Receiver operating characteristics were used. Classification of severity was based on the distribution of SHAI-14 scores reported by patients with clinically significant health anxiety.

RESULTS

The area under the curve (AUC) values were high in all scenarios (above 0.95). The optimal cut-off scores on the SHAI-14 were 22 in the psychiatric context, 29 in a setting with low prevalence of psychiatric disorders and 18 versus healthy controls. SHAI-14 scores of 0-27 represented no or mild health anxiety, 28-32 moderate health anxiety and 33-42 substantial health anxiety.

CONCLUSION

Brief self-report measures used as screening instruments are a simple way of gathering information about the presence of specific symptoms and thus a way to detect the likelihood of a diagnosis. The SHAI-14 shows evidence of good diagnostic utility in both clinical and non-clinical settings. However, which cut-off score is to be used, depends on the intended purpose and the setting where the cut-off is used.

Distribution of health anxiety in a general adult population and associations with demographic and social network characteristics

BACKGROUND

Health anxiety (HA) is associated with increased risk of disability, increased health care utilization and reduced quality of life. However, there is no consensus on which factors are important for the level of HA. The aim of this study was to explore the distribution of HA in a general adult population and to investigate whether demographic and social factors were associated with HA.

METHODS

This study used cross-sectional data from the seventh Tromsø study. A total of 18 064 participants aged 40 years or older were included in the analysis. The six-item Whiteley Index (WI-6) with a 5-point Likert scale was used to measure HA. Sociodemographic factors included age, sex, education, household income, quality of friendship and participation in an organized activity.

RESULTS

HA showed an exponential distribution among the participants with a median score of 2 points out of 24 points. In total, 75% had a total score of 5 points or less, whereas 1% had a score >14 points. Education, household income, quality of friendship and participation in organized activity were significantly associated with HA. The variable quality of friendship demonstrated the strongest association with HA.

CONCLUSION

Our study showed an exponential distribution of HA in a general adult population. There was no evident cut-off point to distinguish participants with severe HA based on their WI-6 score, indicating the importance of analysing HA as a complex, continuous construct. HA demonstrated strong associations with quality of friendship and participation in an organized activity.

Anxiety and depression in dry eye patients during the COVID-19 pandemic: Mental state investigation and influencing factor analysis

Objective

Investigate the anxiety and depression states among dry eye (DE) patients during the COVID-19 outbreak and analyze their influence factors.

Methods

The study was conducted in a tertiary eye hospital in Tianjin, China from March–April 2021. Four hundred twenty-eight DE patients were tested with the Ocular Surface Disease Index, Short Healthy Anxiety Inventory, Hospital Anxiety and Depression Scale, and Pittsburgh Sleep Quality Index. Descriptive statistics was used to assess the difference between DE with depression or anxiety among different groups. And multiple linear regression was used to explore factors that influence anxiety and depression in DE patients.

Results

The incidence rates of anxiety and depression among DE patients during COVID-19 were 27.34 and 26.87%, respectively. The proportion with comorbid anxiety and depression was 24.30%. Patients' education level (t = −3.001, P < 0.05; t = −3.631, P < 0.05), course of disease (t = 2.341, P < 0.05; t = 2.444, P < 0.05), health anxiety (t = 3.015, P < 0.05; t = 2.731, P < 0.05), and subjective sleep quality (t = 3.610, P < 0.05; t = 4.203, P < 0.05) had certain influences on anxiety and depression.

Conclusion

The results showed that subjective symptoms of DE patients were related to depression and anxiety. Higher education, shorter disease duration, lower health anxiety levels, and better subjective sleep quality were associated with the reduced depressive and anxiety symptoms in DE patients. These findings could be deemed beneficial to the treatment and prevention of DE during the COVID-19 epidemic.

Factors associated with health anxiety in medical students at a private university in Lima, Peru

INTRODUCTION

There are few studies that examine the factors associated with the different levels of health anxiety in medical students. The objective was to determine the factors associated with the levels of health anxiety in medical students in 2018.

METHODS

An analytical cross-sectional study was carried out with 657 medical students from a private Peruvian university. Participants answered a questionnaire from which information was collected regarding levels of health anxiety (SHAI). For the analysis, linear regression was used to calculate crude and adjusted betas, and their 95% confidence intervals.

RESULTS

The mean health anxiety score was 14 ± 6.7. An association between health anxiety and the year of study is reported, with the second year showing the highest scores. In addition, an association between health anxiety and smoking is highlighted, as there are higher levels in occasional smokers, as well as a weak inverse correlation with age. No association was found with sex, place of birth, or having a first-degree relative that is a doctor or health worker.

CONCLUSIONS

The present study showed that age, year of studies and smoking are associated with health anxiety levels. More studies are required, especially of a longitudinal nature.

Poor respiratory health outcomes associated with high illness worry and alexithymia: Eleven-year prospective cohort study among the working-age population

OBJECTIVE

Poor respiratory health outcomes have been associated with poorer physical health and higher psychological distress. The aim of this study was to investigate whether illness worry, alexithymia or low sense of coherence predict i) the onset of new respiratory disease, ii) respiratory symptoms or iii) lung function among the working-age population, independently of comorbidity mood-, anxiety, or alcohol abuse disorders.

METHODS

The study was conducted among a nationally representative sample of the Finnish population (BRIF8901) aged 30-54 years (N = 2310) in 2000-2001 and was followed up in 2011. Individuals with a diagnosed respiratory disease or a severe psychiatric disorder at baseline were excluded. Lung function was measured by a spirometry test and psychiatric disorders were diagnosed using a structured clinical interview. Structured questionnaires were used to measure self-reported respiratory symptoms and diseases, illness worry, alexithymia, and sense of coherence.

RESULTS

High illness worry predicted an 11-year incidence of asthma (OR 1.47, 95% CI 1.09-1.99, p = 0.01). Alexithymia predicted shortness of breath (OR 1.32, 95% CI 1.13-1.53, p < 0.01) and 11-year incidence of COPD (OR 2.84, 95% CI 1.37-5.88, p < 0.01), even after several adjustments for physical and mental health. Psychological dispositions did not associate with lung function in 2011.

CONCLUSIONS

In the general population, psychological factors that modify health behaviour predicted adverse respiratory health outcomes independently of lung function after 11 years of follow-up. This indicates that considering them part of personalized treatment planning is important for promoting health-related behaviour among the working-age population.

Associations between courses of posttraumatic stress disorder and physical health conditions among Canadian military personnel

BACKGROUND

Posttraumatic stress disorder (PTSD) and physical health conditions commonly co-occur and are both prevalent among military personnel. This study examined how courses of PTSD (no PTSD, remitted, new onset, persistent/recurrent) are associated with physical health conditions, among a population-based sample of Canadian military personnel.

METHOD

We analyzed data from the 2002 Canadian Community Health Survey-Mental Health and Well-being-Canadian Forces supplement (CCHS-CF) and the 2018 Canadian Armed Forces Members and Veterans Mental Health Follow-Up Survey (CAFVMHS; N = 2941). Multivariable logistic regressions examined associations between PTSD courses (reference = no PTSD) and physical health conditions.

RESULTS

In general, physical health conditions were more prevalent among symptomatic PTSD courses compared to no PTSD. After adjustment, new onset PTSD was associated with increased odds of all physical health conditions with the exception of ulcers and cancer (AOR range: 1.41-2.31) and remitted PTSD was associated with increased odds of diabetes (AOR = 2.31).

CONCLUSION

Results suggest that new onset PTSD may be most strongly associated with physical health conditions. Findings may inform targeted screening and intervention methods among military personnel with PTSD and physical health conditions.

Cost Effectiveness of Internet-Delivered Acceptance and Commitment Therapy for Patients with Severe Health Anxiety: A Randomised Controlled Trial

BACKGROUND

Health anxiety is a prevalent and debilitating disorder associated with extensive use of healthcare services and reduced quality of life (QoL). Regional variability in specialised clinics or specialist healthcare providers limits access to evidence-based treatment, which may be overcome by internet-delivered Acceptance and Commitment Therapy (iACT).

OBJECTIVE

This study investigated the cost effectiveness of iACT for severe health anxiety in adults.

METHODS

Based on a Danish randomised controlled trial (March 2016-March 2017), the economic evaluation compared costs and effects between iACT and an active control condition (iFORUM). Effectiveness was measured using self-report questionnaires. The cost analysis applied a societal perspective. Resource use and healthcare costs were extracted from the Danish National Registries. Linear regression analysis was applied using change in costs/effectiveness outcomes as the dependant variable. Time, group, and interaction between time and group were independent variables. The primary outcome was the proportion of clinically significant improvements, defined as a ≥ 25% reduction in two measures of health anxiety. The probability of cost effectiveness was presented in a cost-effectiveness acceptability curve for a range of threshold values for willingness to pay.

RESULTS

No significant differences were detected in healthcare costs between groups; however, the iACT group significantly improved in all effectiveness outcomes. The economic analysis showed that, from the healthcare perspective, iACT was associated with an incremental cost-effectiveness ratio of €33 per additional case of clinically significant improvement compared with iFORUM and that, from the societal perspective, iACT dominated iFORUM because it was more effective and less expensive.

CONCLUSIONS

We found no statistically significant differences in costs between groups; however, iACT for severe health anxiety may be cost effective, as evidenced by significant differences in effect.

Relationship Between Dry Eye Disease and Emotional Disorder: The Mediating Effect of Health Anxiety

Objective

This study aims to investigate the relationship between dry eye disease (DED) and anxiety, as well as DED and depression. Additionally, the influence of health anxiety (HA) on this relationship was determined.

Methods

A total of 206 patients with DED were recruited from Tianjin Medical University Eye Hospital clinic and surveyed using demographic questionnaires, the Ocular Surface Disease Index (OSDI), Hospital Anxiety and Depression Scale (HADS), and Short Health Anxiety Inventory (SHAI). Additionally, they were examined using Keratograph 5M and assessed for DED by corneal fluorescein staining. Regression analysis and the bootstrap method were used to investigate the influence of HA on the relationship between DED and emotional disorders.

Results

Among the 206 patients with DED, 52 (25.24%) and 56 (27.18%) patients showed depression and anxiety, respectively. The OSDI score and HA were positively correlated with depression and anxiety (P &lt; 0.01). The direct effects of OSDI on depression and anxiety were significant (95% confidence interval [CI]: 0.017–0.069; 0.008–0.060). Additionally, the bootstrap test showed significant mediating effects of HA (95% CI: 0.001–0.016; 0.003–0.021). The results suggested that the severity of DED symptoms, as measured by the OSDI score, affected anxiety and depression by a direct and an indirect pathway mediated by HA.

Conclusions

We found a significant correlation between DED and anxiety and depression. Moreover, HA was a mediator of the relationship between DED symptoms and anxiety and depression.

Health anxiety is an important driver of healthcare use

Background

Healthcare use is increasing, and health anxiety (HA) is recognized as an important associated factor. Previous research on the association between HA and healthcare use has mostly explored HA as a dichotomous construct, which contrasts the understanding of HA as a continuous construct, and compared healthcare use to non-use. There is a need for studies that examine the association between healthcare use and the continuum of HA in a general population.

Aim

To explore the association between HA and primary, somatic specialist and mental specialist healthcare use and any differences in the association by level of healthcare use.

Methods

This study used cross-sectional data from the seventh Tromsø study. Eighteen thousand nine hundred sixty-seven participants aged 40 years or older self-reported their primary, somatic specialist and mental specialist healthcare use over the past 12 months. Each health service was categorized into 5 groups according to the level of use. The Whiteley Index-6 (WI-6) was used to measure HA on a 5-point Likert scale, with a total score range of 0–24. Analyses were conducted using unconstrained continuation-ratio logistic regression, in which each level of healthcare use was compared with all lower levels. Morbidity, demographics and social variables were included as confounders.

Results

HA was positively associated with increased utilization of primary, somatic specialist and mental specialist healthcare. Adjusting for confounders, including physical and mental morbidity, did not alter the significant association. For primary and somatic specialist healthcare, each one-point increase in WI-6 score yielded a progressively increased odds ratio (OR) of a higher level of use compared to all lower levels. The ORs ranged from 1.06 to 1.15 and 1.05 to 1.14 for primary and somatic specialist healthcare, respectively. For mental specialist healthcare use, the OR was more constant across levels of use, ranging between 1.06 and 1.08.

Conclusions

In an adult general population, HA, as a continuous construct, was significantly and positively associated with primary, somatic specialist and mental healthcare use. A small increase in HA was associated with progressively increased healthcare use across the three health services, indicating that the impact of HA is more prominent with higher healthcare use.

Metacognitive Beliefs about Uncontrollability Relate Most Strongly to Health Anxiety among U.S.-based non-Latinx White Primary Care Patients: Comparing Strength of Relations with U.S.-based non-Latinx Black and Latinx Primary Care Patients

Metacognitive beliefs have emerged as important to health anxiety, particularly beliefs that health-related thoughts are uncontrollable. Preliminary research examining generalized worry indicates uncontrollability beliefs relate more strongly to anxiety among U.S.-based self-identifying White relative to Black college students. The present study sought to extend that line of research by examining if metacognitive beliefs about the uncontrollability of health-related thoughts differentially relate to health anxiety among self-identifying non-Latinx Black (n = 123), Latinx (n = 104), and non-Latinx White (n = 80) U.S.-based primary care patients. As predicted, although positive associations were seen across all three groups, beliefs that health-related thoughts are uncontrollable more strongly related to health anxiety among White patients compared to both Black and Latinx patients. Those differential relations held in multivariate analyses while statistically controlling for positive depression screening status, generalized anxiety symptom severity, and medical morbidity. Although the effect size surrounding the differential relations was small in magnitude, the present results further support the notion that metacognitive beliefs about uncontrollability relate less strongly to anxiety among U.S.-based ethnoracial minorities compared to White individuals. Potential reasons for the differential relations are discussed, along with additional areas for future research.

Validity and reliability of the diagnostic codes for hypochondriasis and dysmorphophobia in the Swedish National Patient Register: a retrospective chart review

OBJECTIVES

In the International Classification of Diseases, Tenth Edition (ICD-10), hypochondriasis (illness anxiety disorder) and dysmorphophobia (body dysmorphic disorder) share the same diagnostic code (F45.2). However, the Swedish ICD-10 allows for these disorders to be coded separately (F45.2 and F45.2A, respectively), potentially offering unique opportunities for register-based research on these conditions. We assessed the validity and reliability of their ICD-10 codes in the Swedish National Patient Register (NPR).

DESIGN

Retrospective chart review.

METHODS

Six hundred individuals with a diagnosis of hypochondriasis or dysmorphophobia (300 each) were randomly selected from the NPR. Their medical files were requested from the corresponding clinics, located anywhere in Sweden. Two independent raters assessed each file according to ICD-10 definitions and Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision and Fifth Edition criteria. Raters also completed the Clinical Global Impression-Severity (CGI-S) and the Global Assessment of Functioning (GAF).

PRIMARY OUTCOME MEASURE

Per cent between-rater agreement and positive predictive value (PPV). Intraclass correlation coefficients for the CGI-S and the GAF.

RESULTS

Eighty-four hypochondriasis and 122 dysmorphophobia files were received and analysed. The inter-rater agreement rate regarding the presence or absence of a diagnosis was 95.2% for hypochondriasis and 92.6% for dysmorphophobia. Sixty-seven hypochondriasis files (79.8%) and 111 dysmorphophobia files (91.0%) were considered 'true positive' cases (PPV=0.80 and PPV=0.91, respectively). CGI-S scores indicated that symptoms were moderately to markedly severe, while GAF scores suggested moderate impairment for hypochondriasis cases and moderate to serious impairment for dysmorphophobia cases. CGI-S and GAF inter-rater agreement were good for hypochondriasis and moderate for dysmorphophobia.

CONCLUSIONS

The Swedish ICD-10 codes for hypochondriasis and dysmorphophobia are sufficiently valid and reliable for register-based studies. The results of such studies should be interpreted in the context of a possible over-representation of severe and highly impaired cases in the register, particularly for dysmorphophobia.

The uptake and outcomes of Internet-based cognitive behavioural therapy for health anxiety symptoms during the COVID-19 pandemic

BACKGROUND

Internet cognitive behavioural therapy (iCBT) for health anxiety has demonstrated efficacy but has not been evaluated during the COVID-19 pandemic. This study presents the first evaluation of the uptake and outcomes of iCBT for health anxiety during the COVID-19 pandemic.

METHODS

THIS WAY UP is an Australian digital mental health service which delivers iCBT interventions to community members. We compared the uptake of THIS WAY UP's iCBT course for health anxiety in an Australian adult sample who started the course before the pandemic (12th September 2019-11 th March 2020) to during the pandemic (12th March to 11th June 2020). The course was accessible to Australian adults over 18 years old, with no inclusion criteria. Outcomes included course registrations and commencements, lesson and course completion, and self-reported health anxiety (Short Health Anxiety Inventory), depression (Patient Health Questionnaire 9-item) and distress (Kessler-10).

RESULTS

From March to June 2020, we observed significant increases in course registrations (N = 238 vs N = 1057); and course commencements (N = 126 vs. N = 778). Large, significant improvements in health anxiety (g = 0.89), and distress (K10: g = 0.91), and medium improvements in depression (g = 0.55) were found. Course completion during COVID was 30.5%.

CONCLUSIONS

iCBT improved health anxiety during the COVID-19 pandemic, and provides scalable intervention that can address increased demands for mental health services in the community.

Efficacy of internet-delivered acceptance and commitment therapy for severe health anxiety: results from a randomized, controlled trial

BACKGROUND

Health anxiety is common, disabling and costly due to patients' extensive use of health care services. Internet-delivered treatment may overcome barriers of accessibility to specialized treatment. We aimed to evaluate the efficacy of internet-delivered acceptance and commitment therapy (iACT).

METHODS

A randomized, controlled trial of iACT versus an internet-delivered discussion forum (iFORUM), performed in a Danish university hospital setting. Patients self-referred and underwent video-diagnostic assessment. Eligible patients (≥18 years) with health anxiety were randomized to 12 weeks of intervention. The randomization was blinded for the assessor. The primary outcome was between-group unadjusted mean differences in health anxiety symptoms measured by the Whiteley-7 Index (WI-7, range 0-100) from baseline to 6-month follow-up (6-MFU) using intention to treat and a linear mixed model. The study is registered at clinicaltrials.gov, number NCT02735434.

RESULTS

A total of 151 patients self-referred, and 101 patients were randomized to iACT (n = 53) or iFORUM (n = 48). A mean difference in change over time of 19.0 points [95% confidence interval (CI) 10.8-27.2, p < 0.001] was shown on the WI-7, and a large standardized effect size of d = 0.80 (95% CI 0.38-1.23) at 6-MFU. The number needed to treat was 2.8 (95% CI 1.8-6.1, p < 0.001), and twice as many patients in iACT were no longer clinical cases (35% v. 16%; risk ratio 2.17, 95% CI 1.00-4.70, p = 0.050). Adverse events were few and insignificant.

CONCLUSIONS

iACT for health anxiety led to sustained effects at 6-MFU. The study contributes to the development of easily accessible treatment options and deserves wider application.

Predictors of Persistence of Anxiety, Hyperarousal Stress, and Resilience During the COVID-19 Epidemic: A National Study in Iran

Background: The coronavirus pandemic can cause unprecedented global anxiety, and, in contrast, resilience can help the mental health of people in stressful situations. This study aimed to assess anxiety, hyperarousal stress, the resilience of the Iranian population, and their related factors during the coronavirus disease 2019 (COVID-19) epidemic. Methods: A cross-sectional study was conducted in 31 provinces in Iran between March 18 and 25, 2020. A four-part questionnaire, including the demographic information, the State-Trait Anxiety Inventory (STAI-y1-a 20-item standard questionnaire for obvious anxiety), the Connor-Davidson Resilience Scale (CD-RISC-a 25 item standard questionnaire), and the stress hyperarousal subscale from the Impact of Event Scale-Revised (IES-R), was used to collect data. The ordinal multivariable generalized estimating equation (GEE) model was used to identify correlates of the psychological factors mentioned above. The Fisher exact test was used to investigate the relationship between anxiety, stress, resilience, and the COVID-19 outbreak. All analyses were conducted with SPSS 26 and GIS 10.71. Results: The findings show that most people had moderate-to-severe anxiety (80.17%) and a high level of resilience (96.4%) during the COVID-19 epidemic. The majority of participants had a moderate level of stress (58.9%). The lowest and highest prevalences of psychiatric disorders were in Sistan and Baluchestan (3.14 cases per 100,000 people) and Semnan (75.9 cases per 100,000 people) provinces, respectively. Men and unmarried people were the only variables significantly associated with anxiety and resilience. Age, gender, and education were significantly associated with hyperarousal stress. Conclusion: The high and moderate levels of anxiety and stress in Iranians can have negative effects on the well-being and performance of the people and can lead to serious problems. Also, high resilience during negative life events (such as the COVID-19 pandemic) is associated with the well-being in the lives of people. The results of this study can be used in interventions and other psychological studies.

Number of musculoskeletal pain sites leads to increased long-term healthcare contacts and healthcare related costs - a Danish population-based cohort study

BACKGROUND

People with musculoskeletal pain seek more healthcare than the general population, however little is known about the long-term effect on healthcare use. The aim of this study was to examine the consequences of number of musculoskeletal pain sites on long-term care-seeking and healthcare-related costs and explore how health anxiety influences this relationship.

METHODS

We conducted a Danish population-based longitudinal cohort study of 4883 participants combining self-reported survey data from 2008 with ten-year follow-up data from national health registers. Using a causal inference framework, we examined associations between number of pain sites (range 0-7)/level of health anxiety (high/low level) and face-to-face healthcare contacts/healthcare-related costs. Data were analyzed using negative binomial regression with generalized estimating equations. Regression models were adjusted for sex, age, duration of pain, level of education, comorbidity, personality traits, risk of depression, marital status, physical job exposure, and previous healthcare utilization.

RESULTS

For each additional pain site general healthcare contacts (Incidence Rate Ratio (IRR): 1.04 (95% CI: 1.03-1.05)), healthcare-related costs (IRR: 1.06 (95% CI: 1.03-1.08) and musculoskeletal healthcare contacts (IRR: 1.11 (95% CI:1.09-1.14) increased. Those with high levels of health anxiety at baseline had a slightly higher number of general healthcare contacts (IRR 1.06 (1.01-1.11), independent of number of pain sites. However, level of anxiety did not influence the effect of number of pain sites on any healthcare use or cost outcomes.

CONCLUSIONS

We found evidence for a causal association between increasing number of pain sites and greater healthcare use and cost, and high levels of health anxiety did not increase the strength of this association. This suggests that number of pain sites could be a potential target for biopsychosocial interventions in order to reduce the need for future care-seeking.

The predictive value of patient, therapist, and in-session ratings of motivational factors early in remote cognitive behavioural therapy for severe health anxiety

OBJECTIVES

Remote psychotherapy and the prevalence of Severe Health Anxiety (SHA) are both growing as a result of the COVID-19 pandemic. Remotely delivered Cognitive Behavioural Therapy (rCBT) for SHA is evidenced as effective, but many who seek help do not benefit. Motivational processes can influence outcomes, but it is unclear what assessment methods offer the best clinical utility in rCBT for SHA.

DESIGN

This study compared the predictive validity of patient, therapist and in-session ratings of motivational factors taken at session two of rCBT for SHA among high healthcare users experiencing multimorbidity.

METHODS

Motivational factors were assessed for 56 participants who attended at least two sessions of CBT for SHA delivered via video-conferencing or telephone. Following session two, therapists and patients completed online assessments of patient motivation. Two trained observers also rated motivational factors and therapeutic alliance from in-session interactions using session two recordings and transcripts. Multilevel modelling was used to predict health anxiety and a range of secondary health outcomes from motivation assessments.

RESULTS

Where patients were more actively engaged in discussion of positive changes during session two, greater outcome improvements ensued in health anxiety and all secondary outcomes. Conversely, larger proportions of session two spent describing problems predicted poorer outcomes. Therapist and patient assessments of motivation did not predict health anxiety, but therapist assessments of client confidence and motivation predicted all secondary outcomes.

CONCLUSIONS

Motivation remains an important process in CBT when delivered remotely, and motivational factors may predict outcomes more consistently from in-session interactions, compared to self-reports.

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.

Acupuncture Combined With Emotional Therapy of Chinese Medicine Treatment for Improving Depressive Symptoms in Elderly Patients With Alcohol Dependence During the COVID-19 Epidemic

Objective: We aimed to analyze the characteristics and psychological mechanism of depressive symptoms in elderly patients with alcohol dependence under the COVID-19 epidemic and to observe the effect of acupuncture combined with emotional therapy of Chinese medicine treatment on depressive symptoms in elderly patients with alcohol dependence.

Methods: Sixty patients were randomly divided into two groups. One group was treated by a set of emotional therapy of Chinese medicine treatment for 12 weeks (control group). One group was treated by a set of acupuncture combined with emotional therapy of Chinese medicine treatment for 12 weeks (treatment group). We compared the curative effect between the control group and the treatment group, the mean alcohol consumption, the SF-36 scores before and after treatment, and the scores of Hamilton Depression Scale before and after treatment of 3, 6, and 9 weeks.

Results: Based on the cognitive behavior model, the characteristics and psychological mechanism of depression in elderly patients with alcohol dependence under the COVID-19 epidemic situation were summarized. The total effective rate of the control group was 60%, and that of the treatment group was 100% (p < 0.05). The alcohol consumption of the patients in each group decreased significantly after treatment (p < 0.05), and there was no significant difference in alcohol consumption between the treatment group and the control group (p > 0.05). After 12 weeks of treatment, there were significant differences in PF, RF, physical pain, general health status, energy, and mental health between the treatment group and the control group (p < 0.05). Before and after treatment, there were significant differences in PF, RF, physical pain, general health, energy, emotional function, and mental health (p < 0.05) of the treatment group. The PF, energy, and mental health of the control group were significantly different before and after treatment (p < 0.05). There was no significant difference between the treatment group and the control group in the scores of Hamilton Depression Scale before treatment. There was significant difference between the treatment group and the control group in the scores of Hamilton Depression Scale at 3, 6, and 9 weeks after treatment.

Conclusion: Attention, cognition, emotion, behavior, and physical response reinforce each other, creating a vicious cycle that reinforces and sustains the depressive symptoms of elderly alcohol dependence under the COVID-19 epidemic, and acupuncture combined with emotional therapy of Chinese medicine treatment for improving the depressive symptoms of elderly alcohol dependence during the epidemic period of COVID-19 has a brilliant therapeutic effect.

Gender differences in health anxiety and musculoskeletal symptoms during the COVID-19 pandemic

BACKGROUND

Health anxiety is often associated with musculoskeletal symptoms and gender, but there are limited studies that investigate these relationships during the COVID-19 pandemic.

OBJECTIVE

We aimed to compare the genders regarding health anxiety and musculoskeletal symptoms during the COVID-19 pandemic and to investigate the relationship of musculoskeletal symptoms with physical activity and health anxiety.

METHODS

Assessments were performed through an online questionnaire. Eighty-five males and eighty-five females were included by matching genders in terms of age, body mass index, education level, number of days spent at home during the pandemic, and physical activity. The Short Health Anxiety Inventory, the International Physical Activity Questionnaire-Short Form, and the Nordic Musculoskeletal Questionnaire were used to assess health anxiety, physical activity, and musculoskeletal symptoms, respectively.

RESULTS

Females had a higher level of health anxiety and more musculoskeletal symptoms than males (p< 0.05). There were weak to moderate correlations in females and weak correlations in males between musculoskeletal symptoms and health anxiety (p< 0.05). Also, a weak negative correlation was found between physical activity and musculoskeletal symptoms in both genders (p< 0.05).

CONCLUSIONS

Females are more anxious and have more musculoskeletal symptoms during the pandemic than males. Also, health anxiety is related to musculoskeletal symptoms in both genders.

Continuity of health anxiety from childhood to adolescence and associated healthcare costs: a prospective population-based cohort study

BACKGROUND

Severe health anxiety (HA) is characterized by excessive and impairing worry and preoccupation with health issues and can cause increased and unnecessary medical examinations. HA in childhood and adolescence is scarcely explored, hindering the potential for prevention and early intervention.

METHODS

HA was assessed in 1,278 children/youths at two time points at ages 11 and 16 years in a general population-based birth cohort. Register-based data on costs related to nonhospital-based primary and secondary somatic health services were obtained over the follow-up period. The presence of functional somatic symptoms, emotional disorders and chronic somatic illness at baseline were included as covariates.

RESULTS

High HA (top 10% score) at age 11 predicted high HA at age 16 (relative risk [RR] 2.03, 95% CI: 1.26-3.31). The group with persistent HA was small (n = 17, 1.3%), resulting in broad confidence intervals. The statistical effect of HA at age 11 on HA at age 16 was heavily reduced after adjustment for sex and all covariates (RR: 1.49, 95% CI: 0.85-2.60). In the adjusted model, somatic illness at age 11 (RR: 1.91, 95% CI: 1.22-2.98) and female sex (RR: 3.33, 95% CI: 2.01-5.50) were independently associated with HA at age 16. Persistent HA was associated with approximately doubled healthcare costs compared to the group with consistently low HA. Incident HA at age 16 was associated with increased costs over follow-up. The increased costs were not explained by chronic somatic illness.

CONCLUSIONS

A small subgroup of children had persistent high levels of HA from late childhood to adolescence and displayed increased healthcare costs. Female sex and chronic somatic disorders at age 11 were independent risk factors of HA at age 16. These findings provide potential means of early identification and of therapeutic levers. Further intervention development and evaluation are needed.

Assessing the psychological impact of COVID-19 outbreak and its related factors on Lebanese individuals with physical disabilities

Background

In February 2020, the Lebanese authorities announced the first Coronavirus 2019 (COVID-19) case. Since then, the cases increased significantly, but information on the public’s psychological status and specifically individuals with physical disabilities is still limited.

Purpose

The study aims to assess the psychological impact of the COVID-19 outbreak on Lebanese individuals with physical disabilities and study the associated factors.

Materials and methods

This is a cross-sectional study involving 118 individuals with physical disabilities. Each filled out an online survey with three sections: a personal questionnaire, the Arabic versions of the Hopkins Symptom Checklist-25 and the Fear of COVID-19 scale. Data regarding participants’ baseline characteristics, fear, anxiety, and depression were collected and analyzed using the Chi-square test and regressions models.

Results

Individuals with physical disabilities exhibited mild fear of COVID-19, with fear being correlated with age, educational level, and employment status. Furthermore, 22.9% of the population was found to be anxious, and 31.5% were depressed. Anxiety was associated with both marital status and employment status. Finally, depression was proved to be influenced by marital status, employment, and educational level.

Conclusion

Results extracted showed that individuals with physical disabilities require substantial attention in order to manage their psychological state during pandemics.

The Predictive Value of Health Anxiety for Cancer Incidence and All-Cause Mortality: A 44-Year Observational Population Study of Women

OBJECTIVE

Long-term data concerning mortality and serious illness as a function of health anxiety are scarce. We aimed to study health anxiety in relation to long-term mortality and cancer morbidity among women.

METHODS

A Swedish population sample of women (n = 770; ages, 38-54 years) took part in a general medical and psychiatric examination in 1968 to 1969 and were followed up until 2013 in national Swedish registries for all-cause mortality and first diagnosis of cancer. A modified version of the Whiteley Index questionnaire (maximum score, 12) was used to measure health anxiety. Scores were trichotomized based on quartiles as no (score 0, lowest quartile), mild-moderate (score 1-2, middle quartiles), and high (score ≥3, highest quartile) health anxiety. Risks of death and cancer were evaluated with Cox regression models.

RESULTS

Compared with women with mild-moderate health anxiety levels, women with no health anxiety had a higher risk of death (age-adjusted hazard ratio [HR] = 1.22, 95% confidence interval [CI] = 1.00-1.49; fully adjusted for baseline sociodemographic, mental, and physical health variables: HR, 1.44, 95% CI = 1.17-1.76). Women with high health anxiety levels had a greater risk of death in age-adjusted analysis (HR = 1.26, 95% CI = 1.04-1.54; fully adjusted HR = 1.21, 95% CI = 0.98-1.49). For both groups, the mortality risk was time dependent and declined during follow-up. We observed no between-group differences in the risk of cancer.

CONCLUSIONS

In this population-based cohort of midlife women, health anxiety was moderately associated with mortality in a U-shaped fashion. Absence of health anxiety entailed the greatest risk when other factors were taken into account.

Factors Associated with Health Anxiety in Medical Students at a Private University in Lima, Peru

INTRODUCTION

There are few studies that examine the factors associated with the different levels of health anxiety in medical students. The objective was to determine the factors associated with the levels of health anxiety in medical students in 2018.

METHODS

An analytical cross-sectional study was carried out with 657 medical students from a private Peruvian university. Participants answered a questionnaire from which information was collected regarding levels of health anxiety (SHAI). For the analysis, linear regression was used to calculate crude and adjusted betas, and their 95% confidence intervals.

RESULTS

The mean health anxiety score was 14±6.7. An association between health anxiety and the year of study is reported, with the second year showing the highest scores. In addition, an association between health anxiety and smoking is highlighted, as there are higher levels in occasional smokers, as well as a weak inverse correlation with age. No association was found with sex, place of birth, or having a first-degree relative that is a doctor or health worker.

CONCLUSIONS

The present study showed that age, year of studies and smoking are associated with health anxiety levels. More studies are required, especially of a longitudinal nature.
