Examining the Whiteley Index-6 as a screener for DSM-5 presentations of severe health anxiety in primary care

Does health anxiety and vaccine concern predict self-reported adverse events following COVID-19 vaccination?-A Danish national cohort study

OBJECTIVES

The nocebo effect refers to an expectation of sickness that leads to sickness in the expectant. Studies have found COVID-19 vaccines to be associated with the nocebo effect. However, the literature in this field is sparse yet important with the continuation of booster vaccines.

STUDY DESIGN

National cohort study.

METHODS

This study used data from the Danish national cohort "BiCoVac", which contains self-reported information on both health anxiety and specific COVID-19 vaccine concern, as well as 19 systemic AEs following COVID-19 vaccination. Simple and multiple logistic regression was used to estimate the association between health anxiety and specific COVID-19 vaccine concern with having one or more systemic AEs following COVID-19 vaccination. Inverse probability weights were used to compensate for the initial dropout and loss to follow-up.

RESULTS

Of the 85,080 participants in the study, 4 % reported health anxiety, 30 % reported specific COVID-19 vaccine concern, and 26 % one or more systemic AEs following vaccination. After adjusting for covariates, participants with health anxiety had higher odds of reporting one or more systemic AEs following vaccination compared to those without (OR, 1·21 CI 95 % [1·10; 1·33]). For specific COVID-19 vaccine concern, the OR was 1·51 CI 95 % [1·45; 1·58].

CONCLUSIONS

Participants with specific COVID-19 vaccine concern had higher odds of reporting one or more systemic AEs following vaccination compared with those who had no specific COVID-19 vaccine concern. There might be a potential to reduce AEs, with positive framing of AEs and information about nocebo. Reporting of AEs was also associated with health anxiety, but to a lesser degree.

Subjective cognitive concerns not related to objective impairment in patients with somatic symptom and related disorders

OBJECTIVES

Patients with Somatic Symptom and Related Disorders (SSRD) report subjective cognitive concerns, and research indicates that they show objective cognitive impairment. This study explored the value of subjective concerns flagging objective impairment. Furthermore, we investigated whether coping moderated this relationship, and the role of depressive symptomatology.

METHOD

In a cross-sectional design, objective impairment was measured with an extensive neuropsychological assessment; subjective concerns with the Cognitive Failure Questionnaire; coping styles with the Coping Inventory of Stressful Situations; and symptoms of depression with the Patient Health Questionnaire- 9.

RESULTS

The results show that subjective concerns are of limited value in signaling objective impairment in patients with SSRD. Regression analyses performed on data from 225 patients showed that symptoms of depression (β = .32) were the main predictor of subjective concerns, which were unrelated to objective impairment. Coping was not a moderator, but patients with emotion-oriented coping styles had more subjective concerns (β=.40), and conversely, patients with avoidance- and/or task-oriented coping styles had less (respectively, β=-.27 and β=-.24).

CONCLUSIONS

These results align with the Somatosensory Amplification Theory; patients with SSRD may amplify benign cognitive failures and experience them as intrusive, noxious, and more intense. In patients with SSRD, subjective cognitive concerns are more related to psychological constructs (symptoms of depression and coping styles) than to objective impairment.

Acceptance, Satisfaction, and Preference With Telemedicine During the COVID-19 Pandemic in 2021-2022: Survey Among Patients With Chronic Pain

BACKGROUND

The COVID-19 pandemic has forced many health care providers to make changes in their treatment, with telemedicine being expanded on a large scale. An earlier study investigated the acceptance of telephone calls but did not record satisfaction with treatment or patients' preferences. This warranted a follow-up study to investigate acceptance, satisfaction, and preferences regarding telemedicine, comprising of phone consultations, among health care recipients.

OBJECTIVE

The primary aim was to assess the acceptance and satisfaction of telemedicine during the subsequent months of 2021-2022, after the initial wave of the COVID-19 pandemic in Switzerland. Furthermore, we aimed to assess patients' preferences and whether these differed in patients who had already experienced telemedicine in the past, as well as correlations between acceptance and satisfaction, pain intensity, general condition, perception of telemedicine, and catastrophizing. Finally, we aimed to investigate whether more governmental restrictions were correlated with higher acceptance.

METHODS

An anonymous cross-sectional web-based survey was conducted between January 27, 2021, and February 4, 2022, enrolling patients undergoing outpatient pain therapy in a tertiary university clinic. We conducted a descriptive analysis of acceptance and satisfaction with telemedicine and investigated patients' preferences. Further, we conducted a descriptive and correlational analysis of the COVID-19 stringency index. Spearman correlation analysis and a chi-square test for categorical data were used with Cramer V statistic to assess effect sizes.

RESULTS

Our survey was completed by 60 patients. Telemedicine acceptance and satisfaction were high, with an average score of 7.6 (SD 3.3; on an 11-point Numeric Rating Scale from 0=not at all to 10=completely), and 8.8 (SD 1.8), respectively. Respondents generally preferred on-site consultations to telemedicine (n=35, 58% vs n=24, 40%). A subgroup analysis revealed that respondents who already had received phone consultation, showed a higher preference for telemedicine (n/N=21/42, 50% vs n/N=3/18, 17%; χ22 [N=60]=7.5, P=.02, Cramer V=0.354), as well as those who had been treated for more than 3 months (n/N=17/31, 55% vs n/N=7/29, 24%; χ22 [N=60]=6.5, P=.04, Cramer V=0.329). Acceptance of telemedicine showed a moderate positive correlation with satisfaction (rs{58}=0.41, P<.05), but there were no correlations between the COVID-19 stringency index and the other variables.

CONCLUSIONS

Despite high acceptance of and satisfaction with telemedicine, patients preferred on-site consultations. Preference for telemedicine was markedly higher in patients who had already received phone consultations or had been treated for longer than 3 months. This highlights the need to convey knowledge of eHealth services to patients and the value of building meaningful relationships with patients at the beginning of treatment. During the COVID-19 pandemic, the modality of patient care should be discussed individually.

Pandemic life in families with health anxiety symptoms, parental perspectives

Background

The covid-19 pandemic has influenced children and parents worldwide. The pandemic has also been suggested to especially affect and exacerbate health anxiety (HA) symptoms in children and adolescents. However, there is limited understanding of the potential mechanisms challenges of families where parents themselves experience mental health issues such as high degree of HA symptoms.

Objective

The aim of this study was to explore parental experiences of pandemic life in families with continuously high levels of HA symptoms during the covid-19 pandemic.

Method

Six parents, identified with high levels of HA symptoms, participated in qualitative individual semi-structured interviews. Interviews were analysed according to Interpretative Phenomenological Analysis principles.

Results

Three main themes emerged. Theme 1) "Anxious children in a pandemic world" explores how pandemic - independent child factors including anxious temperament may have influenced the child pandemic experience. Theme 2) "Parental influences on child anxiety" describes parental reflections on their possible influence on child anxious thoughts. Theme 3) "Living with pandemic guidelines and restrictions" demonstrates the varying parental experiences of interventions and how these may affect HA thoughts.

Conclusion

Parents who themselves experience HA symptoms see their children, who also experience HA symptoms, to be particularly susceptible and vulnerable to both content and rhetoric of pandemic information. These children may however, experience school lockdown to be anxiety relieving. Parents who themselves have illness-related fears may not see themselves as perpetuating for their child's anxious thoughts.

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.

[Integrated Care for Patients with Somatic Symptom Disorder in Primary Care - A Qualitative Participatory Evaluation of a Randomised Feasibility Trial]

OBJECTIVE

The VISION intervention is a manualized short-term treatment for people with somatic symptom disorder, integrated into the primary care and delivered by psychotherapists via video consultations. As an innovative technology-based approach, the intervention was most recently piloted in a randomized feasibility trial. During the qualitative accompanying study presented here, the intervention was evaluated and optimised from the user perspective of patients who participated in the feasibility study.

METHODS

We interviewed a total of N=10 patients included in the intervention group in three semi structured focus group discussions focusing on how they (1) assess the intervention in terms of acceptance and individual benefit and (2) which adjustments are necessary from the user perspective for further optimization of the intervention. We performed a qualitative content analysis using MAXQDA Plus 2022.

RESULTS

Respondents reported initial reservations on their part regarding care via video consultation. After a brief period of habituation, the intervention was universally accepted. Main suggestions for improvement included a stronger focus on supporting patients find follow-up psychotherapy (if indicated) more flexible settings (e. g., location of video consultation), and a stronger integration of treatment into primary care.

DISCUSSION AND CONCLUSION

The study provides systematically elaborated comprehensive findings on participants' practical experiences with the intervention. The model is appropriate for treating people with somatic symptom disorder. Before implementation, important suggestions for improvement should be thoroughly considered with continued patient and public involvement.

Measurement Invariance of Scores on the Somatic Symptom Scale-8: National Sample of Non-Clinical Adults in the United States

Objective

The aim of the present study was to test the factorial invariance and convergent validity evidence of scores on the Somatic Symptom Scale (SSS)-8 with a national sample of adults living in the United States.

Method

A data collection contracting service was hired to recruit a national, non-clinical sample (N = 821) of adults in the United States stratified by the census data for age, gender, ethnicity, and geographic location.

Results

Factorial invariance testing via multiple-group confirmatory factor analysis revealed strong factorial invariance evidence (configural, metric, and scalar) of SSS-8 scores across gender, ethnicity, help-seeking history, education, and income. Convergent validity testing displayed strong correlations between SSS-8 scores and the following established measures: Patient Health Questinaire-9, Generalized Anxiety Disorder-7, and Mental Health Inventory-5.

Conclusion

Collectively, the results suggest that professional counselors can use the SSS-8 to enhance somatic symptomology screening efforts with adults living in the United States.

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.

Polypharmacy Pattern in Iran: A Comprehensive Analysis of a Large Prescription Database

Background

Polypharmacy is a significant patient safety concern.

Objectives

This study aims to estimate the prevalence of polypharmacy, its continuity and associated factors, and common medication classes among a large outpatient population in East Azerbaijan province, Iran.

Methods

A retrospective prescription data analysis was performed. The cohort included all ≥ 20 years old subjects with at least one prescription filled during the main three-month study period (2020 March 1 - 2020 May 31). Polypharmacy was defined as being exposed to more than four different medications during the main study period, and continuous polypharmacy was defined as being exposed to more than four medications during both the main study period and follow-up period (2020 October 1 - 2020 December 31). The frequency and prevalence of polypharmacy, along with predictive factors, were estimated. We performed multivariate logistic regression and estimated odds ratios (ORs) to investigate the risk factors for polypharmacy.

Results

307,820 patients included (mean age 49.8 years, 62.9% female, mean drug use 3.7 (SD = 2.6). Polypharmacy was observed in 28.3% (CI: 28.1 - 28.4), of which 36.6% experienced continuous polypharmacy. The odds of being exposed to polypharmacy increased with being female, increasing age, and exposure to chronic conditions. The groups of medications most utilized by polypharmacy patients were those indicated for gastro-esophageal reflux diseases, beta-blocking agents, antidepressants, blood glucose-lowering drugs, and antithrombotic agents.

Conclusions

Strategies should be formulated to inform healthcare policymakers and providers about the magnitude of the polypharmacy phenomenon, associated factors, and the common medication classes involved.

Estimated frequency of somatic symptom disorder in general practice: cross-sectional survey with general practitioners

BACKGROUND

Somatic symptom disorder (SSD) is the successor diagnosis of somatoform disorder in the 5th Edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Relevance and frequency of SSD and its clinical symptoms in general practice are still unknown. We estimate frequencies of patients fulfilling the diagnostic criteria of SSD in general practice.

METHODS

Mailed and online survey with general practitioners (GP) in Germany using a cross-sectional representative sample from registries of statutory health insurance physicians. GPs estimated percentages of their patients who show the clinical symptoms of SSD according to DSM-5; that is, one or more burdensome somatic symptoms (A criterion), excessive symptom- or illness-related concern, anxiety, or behaviour (B criterion), and persistence of the symptoms over at least 6 months (C criterion). Statistical analysis used means and confidence intervals of estimated patient proportions showing SSD symptoms. Frequency of full-blown SSD was based on the products of these proportions calculated for each GP.

RESULTS

Responses from 1728 GPs were obtained. GPs saw the clinical symptoms of SSD fulfilled (A and B criteria) in 21.5% (95% CI: 20.6 to 22.3) of their patients. They further estimated that in 24.3% (95% CI: 23.3 to 25.2) of patients, symptoms would persist, yielding a total of 7.7% (95% CI: 7.1 to 8.4) of patients to have a full-blown SSD.

CONCLUSIONS

We estimate a frequency of 7.7% of patients in general practice to fulfil the diagnostic criteria of SSD. This number may figure as a reference for the yet to be uncovered prevalence of SSD and it indicates a high clinical relevance of the clinical symptoms of SSD in general practice.

Health anxiety symptoms in Danish children during the first lockdown period of the COVID-19 pandemic: an Odense Child Cohort study

PURPOSE

The coronavirus disease 2019 (COVID-19) pandemic has a severe impact on the general population. During the pandemic, children may develop emotional and psychological symptoms, including increased worries about health and illness, known as health anxiety symptoms (HASs). We aimed to explore HAS in 7-9-year-old children from the Danish Odense Child Cohort (OCC) during the first COVID-19 lockdown period in Denmark, and to examine associations with potential risk factors.

MATERIAL AND METHODS

OCC is a cohort of children born between 2010 and 2012, which originally recruited 2874 of 6707 pregnancies (43%). Among the current OCC population of 2430 singleton children, 994 participated in this study (response rate 40%). Children and their parents filled out questionnaires about child HAS, family exposure to COVID-19 infection and parental HAS. Adjusted odds ratios (aORs) were calculated between high score child HAS (≥90th percentile) and covariates by use of logistic regression.

RESULTS

Most children (n = 686, 69%) reported few worries about their health. Children reporting high score HAS also had higher levels of internalizing symptoms at age 5; aOR 2.15 (1.20;3.85), p = .010, and higher levels of maternal and paternal HAS; aOR 2.40 (1.44;3.97), p = .001, and 2.00 (1.10;3.65), p = .023, whereas no association with child sex or familial exposure to COVID-19 was detected (n = 65, 6.5%).

CONCLUSIONS

High score child HAS during the first lockdown period of the COVID-19 pandemic was not associated with family exposure to COVID-19 infection, but to being a more anxious child a priori and to HAS in parents.

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 overlapping relationship among depression, anxiety, and somatic symptom disorder and its impact on the quality of life of people with epilepsy

Background:

Emotional disorder is an important indicator for assessing the quality of life (QOL) of people with epilepsy (PWE). Depression, somatic symptom disorder (SSD) and anxiety are among the most frequently occurring mental disorders and overlap with each other.

Objectives:

This study examines the overlap of these three emotional disorders and their effects separately and in combination on the QOL of PWE.

Design:

Cross-sectional study.

Data Sources and Methods:

Adults attending our epilepsy clinic between 1 July 2020 and 1 May 2022 were consecutively enrolled. They were screened for depression, SSD, and anxiety by structured interviews, and demographic, epilepsy-related and QOL indicators were collected. Multivariate analysis, propensity score matching (PSM) and stratified analysis were used to explore the effects of their respective and combined effects on QOL.

Results:

Among the 749 patients, 189 patients (25%) were diagnosed with depression, 183 patients (24%) were diagnosed with SSD, and 157 patients (21%) were diagnosed with anxiety. The frequency of occurrence of each emotional disorder together with other emotional disorders was higher than the frequency of occurrence of an emotional disorder alone. Depression, SSD, and anxiety all had an independent effect on QOL of PWE ( p < 0.001). Depression had the greatest effect, followed by SSD, and then anxiety ( β: multivariate analysis, −11.0 versus –7.8 versus –6.5; PSM, −14.7 versus –9.4 versus –6.8). The QOL of PWE decreased more significantly with the increasing number of comorbid emotional disorders ( β: –12.1 versus –20.7 versus –23.0).

Conclusion:

It is necessary to screen for three emotional disorders, that is, depression, SSD, and anxiety, in PWE. Attention should be paid to people with multiple comorbid emotional disorders.

Commentary on: Understanding Breast Implant Illness

BACKGROUND

Breast implant surgery is the most common plastic surgery procedure performed globally. A subset of women with breast implants report experiencing a myriad of disabling and distressing physical and psychological symptoms attributed to their implants. Social media groups have coined the condition "breast implant illness" (BII). Little to no scientific research currently exists for BII.

OBJECTIVES

The aim of this study was to investigate the experiences of women with BII (both those with implants still in place and those who have explanted) and compare them with those of a control group of women with implants who do not report BII.

METHODS

Women with self-reported BII and implants still in place (n = 51), self-reported BII who had explanted (n = 60), and women with implants in place without BII (n = 58) completed online self-report questionnaires about their symptoms, physical and mental health, health service use patterns, and lifestyle factors (eg, exercise, smoking, alcohol consumption).

RESULTS

Women with BII, regardless of whether they had undergone explant surgery, reported experiencing more severe somatic symptoms, higher depression, anxiety and health anxiety, and poorer physical health than women without BII.

CONCLUSIONS

These findings highlight the need for further investigation into the causes, risk factors, long-term effects, and potential interventions for women who experience BII.

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.
