The development and initial validation of the cyberchondria severity scale (CSS)

Health anxiety, cyberchondria, and coping in the current COVID-19 pandemic: Which factors are related to coronavirus anxiety?

According to cognitive-behavioral models, traits, triggering events, cognitions, and adverse behaviors play a pivotal role in the development and maintenance of health anxiety. During virus outbreaks, anxiety is widespread. However, the role of trait health anxiety, cyberchondria, and coping in the context of virus anxiety during the current COVID-19 pandemic has not yet been studied. An online survey was conducted in the German general population (N = 1615, 79.8 % female, Mage = 33.36 years, SD = 13.18) in mid-March 2020, which included questionnaires on anxiety associated with SARS-CoV-2, trait health anxiety, cyberchondriaPandemic (i.e. excessive online information search), and emotion regulation. The participants reported a significantly increasing virus anxiety in recent months (previous months recorded retrospectively), especially among individuals with heightened trait health anxiety. CyberchondriaPandemic showed positive correlations with current virus anxiety (r = .09-.48), and this relationship was additionally moderated by trait health anxiety. A negative correlation was found between the perception of being informed about the pandemic and the current virus anxiety (r=-.18), with adaptive emotion regulation being a significant moderator for this relationship. The findings suggest that trait health anxiety and cyberchondria serve as risk factors, whereas information about the pandemic and adaptive emotion regulation might represent buffering factors for anxiety during a virus pandemic.

Is cyberchondria a new transdiagnostic digital compulsive syndrome? A systematic review of the evidence

BACKGROUND

Cyberchondria (CYB) has been described relatively recently as a behaviour characterized by excessive online searching for medical information that is associated with increasing levels of health anxiety. Although CYB has received some attention from researchers, there is no consensus about many of its aspects.

AIMS

We describe one of the first reported cases of a treatment-seeking patient with CYB. We review the published literature on the definition of CYB, its assessment, epidemiology, cost and burden, psychological models and mechanisms associated with CYB, relationships between CYB and mental disorders and prevention and treatment strategies.

METHODS

Systematic review of all peer-reviewed papers published within the PubMed, PsycINFO, and Cochrane Library databases.

RESULTS

61 articles were selected. Nearly all the studies were descriptive and cross-sectional recruiting sample mainly from the general/university student population and collecting self-report data via online surveys. Data on epidemiology, clinical features, course, comorbidity and therapeutic interventions were scarce. CYB showed a self-reported association with health anxiety, hypochondriasis and obsessive-compulsive disorder (OCD) as well as other forms of problematic usage of the internet (PUI) The psychological mechanisms associated with CYB include low self-esteem, anxiety sensitivity, intolerance of uncertainty, pain catastrophizing and certain meta-cognitive beliefs.

CONCLUSION

A working definition of CYB includes excessive online health searches that are compulsive and may serve the purpose of seeking reassurance, whilst leading to a worsening of anxiety or distress and further negative consequences. CYB represents a clinically relevant transdiagnostic compulsive behavioural syndrome, closely related to PUI and usually presenting in association with health anxiety, hypochondriasis and/or OCD. CYB is clearly in need of further study and we identify key areas for future research.

Development of an Instrument to Assess Parents' Excessive Web-Based Searches for Information Pertaining to Their Children's Health: The "Children's Health Internet Research, Parental Inventory" (CHIRPI)

Background

People often search the internet to obtain health-related information not only for themselves but also for family members and, in particular, their children. However, for a minority of parents, such searches may become excessive and distressing. Little is known about excessive web-based searching by parents for information regarding their children’s health.

Objective

This study aimed to develop and validate an instrument designed to assess parents' web-based health information searching behavior, the Children’s Health Internet Research, Parental Inventory (CHIRPI).

Methods

A pilot survey was used to establish the instrument (21 items). CHIRPI was validated online in a second sample (372/384, 96.9% mothers; mean age 32.7 years, SD 5.8). Item analyses, an exploratory factor analysis (EFA), and correlations with parents’ perception of their children’s health-related vulnerability (Child Vulnerability Scale, CVS), parental health anxiety (modified short Health Anxiety Inventory, mSHAI), and parental cyberchondria (Cyberchondria Severity Scale, CSS-15) were calculated. A subset of participants (n=73) provided retest data after 4 weeks. CHIRPI scores (total scores and subscale scores) of parents with a chronically ill child and parents who perceived their child to be vulnerable (CVS+; CVS>10) were compared with 2×2 analyses of variances (ANOVAs) with the factors Child’s Health Status (chronically ill vs healthy) and perceived vulnerability (CVS+ vs CVS−).

Results

CHIRPI’s internal consistency was standardized alpha=.89. The EFA identified three subscales: Symptom Focus (standardized alpha=.87), Implementing Advice (standardized alpha=.74) and Distress (standardized alpha=.89). The retest reliability of CHIRPI was measured as r_tt=0.78. CHIRPI correlated strongly with CSS-15 (r=0.66) and mSHAI (r=0.39). The ANOVAs comparing the CHIRPI total score and the subscale scores for parents having a chronically ill child and parents perceiving their child as vulnerable revealed the main effects for perceiving one’s child as vulnerable but not for having a chronically ill child. No interactions were found. This pattern was observed for the CHIRPI total score (η²=0.053) and each subscale (Symptom Focus η²=0.012; Distress η²=0.113; and Implementing Advice η²=0.018).

Conclusions

The psychometric properties of CHIRPI are excellent. Correlations with mSHAI and CSS-15 indicate its validity. CHIRPI appears to be differentially sensitive to excessive searches owing to parents perceiving their child’s health to be vulnerable rather than to higher informational needs of parents with chronically ill children. Therefore, it may help to identify parents who search excessively for web-based health information. CHIRPI (and, in particular, the Distress subscale) seems to capture a pattern of factors related to anxious health-related cognitions, emotions, and behaviors of parents, which is also applied to their children.

Testing the Italian version of the Cyberchondria Severity Scale and a metacognitive model of cyberchondria

Cyberchondria refers to the tendency to excessively and compulsively search for online medical information despite the distress experienced, with consequent impairment of daily-life activities. The current two studies sought to explore (i) the factor structure of the Italian version of the Cyberchondria Severity Scale (CSS) and (ii) a metacognitive model of cyberchondria. Participants were Italian community adults who reported using the Internet to search for health-related information (Study 1: N = 374, Study 2: N = 717). Results from Study 1 supported the Italian version of the CSS exhibiting a five-factor structure, with the resulting scales demonstrating good internal consistency, 5-week test-retest reliability, and generally strong correlations with indices of health anxiety. In Study 2, results of a path analysis showed that the negative metacognitive belief domain ("thoughts are uncontrollable") shared the strongest direct association with each of the five dimensions of cyberchondria, followed by beliefs about rituals. Consistently, the strongest indirect associations were found between "thoughts are uncontrollable" and all the five cyberchondria dimensions via beliefs about rituals. These results provide support for an Italian version of the CSS and the metacognitive conceptualization of cyberchondria.

The impact of internet-delivered cognitive behavioural therapy for health anxiety on cyberchondria

Cyberchondria refers to an emotional-behavioural pattern whereby excessive online searches lead to increased anxiety about one's own health status. It has been shown to be associated with health anxiety, however it is unknown whether existing cognitive behavioural therapy (CBT) interventions targeting health anxiety also improve cyberchondria. This study aimed to determine whether internet-delivered cognitive behavioural therapy (iCBT) for severe health anxiety led to improvements in self-reported cyberchondria and whether improvements in cyberchondria were associated with improvements in health anxiety observed during treatment. Methods: We analysed secondary data from a randomised controlled trial (RCT) comparing an iCBT group (n = 41) to an active control group who underwent psychoeducation, monitoring and clinical support (n = 41) in health anxious patients with a DSM-5 diagnosis of Illness Anxiety Disorder and/or Somatic Symptom Disorder. The iCBT group showed a significantly greater reduction in cyberchondria compared to the control group, with large differences at post-treatment on the Cyberchondria Severity Scale Total scale (CSS; Hedges g = 1.09), and the Compulsion, Distress, Excessiveness subscales of the CSS (g's: 0.8-1.13). Mediation analyses showed improvements in health anxiety in the iCBT group were mediated by improvements in all of the CSS subscales, except for the Mistrust subscale. Conclusions: Internet CBT for health anxiety improves cyberchondria.

Recent Insights Into Cyberchondria

PURPOSE OF REVIEW

The construct of cyberchondria was introduced relatively recently. This article aims to review the conceptualization, theoretical basis and correlates of cyberchondria, as well as its prevention and management.

RECENT FINDINGS

Although there is no consensus, most definitions of cyberchondria emphasize online health research associated with heightened distress or anxiety. The two theoretical models of cyberchondria involve reassurance seeking and specific metacognitive beliefs. Cyberchondria has relationships with health anxiety, problematic Internet use and symptoms of obsessive-compulsive disorder, with public health implications pertaining to functional impairment and altered healthcare utilization. Suggestions about prevention and management of cyberchondria have been put forward, but not tested yet. Research interest in cyberchondria has steadily increased. It is uncertain whether cyberchondria can be considered a distinct entity. Future research should aim to clarify the conceptual status of cyberchondria, quantify its impact and develop evidence-based approaches for a better control of cyberchondria.

Evaluating the Cyberchondria Construct Among Computer Engineering Students in Pune (India) Using Cyberchondria Severity Scale (CSS-15)

Background:

The Internet has become an important tool in day-to-day life. Reading medical data from Internet sources can have a negative impact on the common man. Anxiety due to excess searching for medical information online is known as cyberchondria.

Aim:

To evaluate the cyberchondria construct among the computer engineering students in Pune (India) using Cyberchondria Severity Scale (CSS-15).

Settings and Design:

A cross-sectional study was conducted among third- and fourth-year computer engineering students.

Methods:

The study recruited 180 students. A self-administered, English-translated CSS-15 questionnaire was used to collect the data. The responses were based on the Likert scale. Four constructs were scored from 0 to 4 while the mistrust of medical professional construct was scored in reverse order.

Statistical Analysis:

Descriptive statistics in the form of numbers and percentages were calculated.

Results:

The survey was completed by 171 (95%) participants, 77 females and 94 males with the mean age of 19.77 ± 1.07 years. All (100%) participants were affected by excessiveness and reassurance construct, 92% by distress, and 75% by compulsion. Only 19% were found to be affected by mistrust of a medical professional. Among all the domains, reassurance was severely affected among 52.04% of the participants.

Conclusion:

All the computer engineering students were affected by some or the other constructs of cyberchondria. This indicates that the Internet can affect an individual's mental, physical, and social activity by giving a vast amount of information and cause anxiety or distress related to their search.

What are the Implications of Excessive Internet Searches for Medical Information by Orthopaedic Patients?

BACKGROUND

Cyberchondria may be defined as heightened distress evoked through excessive searches of the internet for medical information. In healthy people, cyberchondria is associated with a greater intolerance of uncertainty and greater health anxiety. These relationships are likely bidirectional. People who have a greater intolerance of uncertainty may be more likely to search the internet for medical information and have greater health anxiety. This greater health anxiety may lead to an increased likelihood of engaging in further internet searches and greater intolerance of uncertainty. These three constructs are important for patients because they impact patient function and health care costs. We were specifically interested in understanding the role of cyberchondria in the association between intolerance of uncertainty and health anxiety among orthopaedic patients because it has not been explored before and because knowledge about these interactions could inform treatment recommendations.

QUESTIONS/PURPOSES

Does cyberchondria mediate (that is, explain) the association between intolerance of uncertainty and health anxiety in orthopaedic patients searching for medical information on the internet, after controlling for potentially confounding variables?

METHODS

This was a cross-sectional study of 104 patients who had searched the internet for any medical information about their current condition. A research assistant approached 155 patients attending two orthopaedic outpatient clinics, one hand and upper extremity service and one sports medicine clinic, during a 3-month period. Ten patients declined to participate and 41 patients were excluded, predominantly because they had never searched for medical information online. The patients completed the Cyberchondria Severity Scale, Intolerance of Uncertainty Scale-short version, Short Health Anxiety Inventory, and a numerical rating scale for pain intensity at baseline, as well as demographic and clinical questionnaires. We performed a series of linear regression analyses to determine whether a greater intolerance of uncertainty predicts greater cyberchondria (mediator) and whether cyberchondria predicts greater health anxiety. Although it is more appropriate to use the language of association (such as "whether cyberchondria is associated with health anxiety") in many observational studies, here, we opted to use the language of causation because this is the conventional language for studies testing statistical mediation.

RESULTS

After controlling for potentially confounding variables including pain intensity, multiple pain conditions, and education, cyberchondria explained 33% of the variance of the effect of intolerance of uncertainty on health anxiety (95% CI, 6.98 to 114.72%; p < 0.001).

CONCLUSIONS

Among orthopaedic patients who search the internet for medical information, a greater intolerance of uncertainty is associated with greater cyberchondria, which is associated with greater anxiety about health. Identifying patients with an intolerance of uncertainty and educating them about the negative role of compulsive searches for medical information may improve the success of orthopaedic treatment. Orthopaedic surgeons should also consider making referrals for cognitive behavioral therapy in these instances to increase the patient's tolerance of uncertainty, decrease internet searching habits, and reduce anxiety about health.

LEVEL OF EVIDENCE

Level III, prognostic study.

Cyberchondria and its Relationships with Related Constructs: a Network Analysis

Cyberchondria denotes repeated online searches for health information that are associated with increasing levels of health anxiety. The aims of this study were to apply network analysis to investigate the extent to which cyberchondria is a distinct construct, ascertain which of the related constructs have the strongest relationships with cyberchondria and investigate whether some of the symptoms of cyberchondria are more central to the construct of cyberchondria. Questionnaires assessing the severity of cyberchondria, health anxiety, obsessive-compulsive disorder symptoms, intolerance of uncertainty, problematic Internet use, anxiety, depression and somatic symptoms were administered to 751 participants who searched for health information online during a previous 3-month period and were recruited from an online crowdsourcing platform. Network analyses were used to compute the networks, perform community detection tests and calculate centrality indices. Results suggest that cyberchondria is a relatively specific syndrome-like construct, distinct from all related constructs and consisting of interrelated symptoms. It has the strongest relationships with problematic Internet use and health anxiety. No symptom of cyberchondria emerged clearly as more central to the construct of cyberchondria. Future research should aim to deepen our understanding of cyberchondria and its links with psychopathology, especially its close relationship with problematic Internet use.

Use of Web-Based Health Services in Individuals With and Without Symptoms of Hypochondria: Survey Study

Background

An increasing number of people consult physicians because of distressing information found online. Cyberchondria refers to the phenomenon of health anxiety because of online health information.

Objective

This study aimed to examine online health research of individuals with and without symptoms of hypochondria and their impact on health anxiety as well as behavior.

Methods

An online survey was conducted. Demographic data, health-related internet use, and general health behavior were assessed. The illness attitude scale was used to record symptoms of hypochondria.

Results

The final sample consisted of N=471 participants. More than 40% (188/471) of participants showed at least some symptoms of hypochondria. Participants with symptoms of hypochondria used the internet more frequently for health-related purposes and also frequented more online services than individuals without symptoms. Most online health services were rated as more reliable by individuals with symptoms of hypochondria. Changes to behavior such as doctor hopping or ordering nonprescribed medicine online were considered more likely by individuals with symptoms of hypochondria.

Conclusions

Results show that individuals with symptoms of hypochondria do not turn to online research as a result of lacking alternatives but rather consult health services on- as well as offline.

Illness Anxiety Disorder: Psychopathology, Epidemiology, Clinical Characteristics, and Treatment

Illness anxiety disorder is a primary disorder of anxiety about having or developing a serious illness. The core feature is the cycle of worry and reassurance seeking regarding health, as opposed to a focus on relief of distress caused by somatic symptoms (as in Somatic Symptom Disorder). Clinically significant health anxiety is common, with estimates ranging up to 13% in the general adult population. There are evidence-based treatments, including psychopharmacology and cognitive behavioral therapy, that can significantly alleviate symptoms. An understanding of the core psychopathology and clinical features of illness anxiety disorder is essential to fostering a working alliance with patients with health anxiety, as is the maintenance of an empathic, curious, and nonjudgmental stance toward their anxiety. Collaboration between medical providers is essential to avoid the pitfalls of excess testing and medical treatment.

The CSS-12: Development and Validation of a Short-Form Version of the Cyberchondria Severity Scale

Cyberchondria is defined as an increase in anxiety about one's health status as a result of excessive online searches. McElroy and Shevlin (2014) developed the first multidimensional, self-report measure of this construct-the Cyberchondria Severity Scale (CSS). The CSS consists of 33 items which can be summed to form a total score, and/or 5 subscale scores. The aim of the present study was to develop a short-form version of the CSS, removing the "Mistrust" subscale. Participants were undergraduate students from two UK universities (N = 661, 73% female, M_age = 22.19 years, SD = 5.88). Students completed the CSS, Short Health Anxiety Inventory (SHAI) and Generalized Anxiety Disorder Assessment (GAD-7). Twelve items were chosen for retention in the short form based on an exploratory factor analysis. These items corresponded to the four factors previously identified in the 33-item scale (minus the "Mistrust" subscale). Confirmatory factor analysis was used to validate the structure of the CSS-12. Confirmatory bifactor modeling indicated that the majority of item covariance was accounted for by a general cyberchondria factor. Construct validity was assessed by examining associations with the SHAI and GAD-7, with stronger correlations observed between the CSS-12 and the SHAI (compared with the GAD-7). The CSS-12 is a brief, reliable, and valid measure of worry/anxiety attributable to excessive online health research.

Self-esteem and cyberchondria: The mediation effects of health anxiety and obsessive–compulsive symptoms in a community sample

Cyberchondria refers to the excessive and repeated searching for medical information on the Internet and may be considered as health-related problematic Internet use. Previous findings indicated that cyberchondria is positively associated with health anxiety and obsessive–compulsive symptoms. Also, research suggests that excessive or problematic Internet use as well as health worries and compulsive behaviors are present among individuals with low self-esteem. This study sought to examine: (1) the association between self-esteem and cyberchondria, and (2) the mediating role of health anxiety and obsessive–compulsive symptoms in the relationship between self-esteem and cyberchondria. Participants (N = 207) from a community sample completed self-report measures assessing global self-esteem, health anxiety, obsessive–compulsive symptoms, and cyberchondria. We found that self-esteem directly predicted cyberchondria and that health anxiety and obsessive–compulsive symptoms parallelly mediated the relationship between self-esteem and cyberchondria. These findings suggest that low self-esteem, health anxiety and obsessive–compulsive symptoms can be considered vulnerability factors for cyberchondria. In addition, the reverse mediation model indicated that cyberchondria potentially predicts self-esteem both directly and through health anxiety and obsessive–compulsive symptoms. The bidirectional relationship among the analyzed variables are discussed in the context of potential psychological predictors and consequences of cyberchondria and possible mechanisms explaining cyberchondria. The current study provides further insight into the conceptualization of cyberchondria and the feasibility of specific treatment directions.

The relationships between health anxiety, online health information seeking, and cyberchondria: Systematic review and meta-analysis

BACKGROUND

Cyberchondria refers to an abnormal behavioral pattern in which excessive or repeated online searches for health-related information are distressing or anxiety-provoking. Health anxiety has been found to be associated with both online health information seeking and cyberchondria. The aims of the present systematic review and meta-analysis were to examine the magnitude of these associations and identify any moderator variables.

METHODS

A systematic literature search was performed across several databases (PsycINFO, PubMed, Embase) and reference lists of included studies.

RESULTS

Twenty studies were included across two independent meta-analyses, with 7373 participants. Random effects meta-analyses showed that there was a positive correlation between health anxiety and online health information seeking [r = 0.34, 95% CI (0.20, 0.48), p < .0001], and between health anxiety and cyberchondria [r = 0.62, 95% CI (0.52, 0.71), p < .0001]. A meta-regression indicated that the age of study participants [Q(1) = 4.58, p = .03] was partly responsible for the heterogeneity found for the relationship between health anxiety and cyberchondria.

LIMITATIONS

The generalizability and validity of our findings are restricted by the methodological limitations of the primary studies, namely, an over-reliance on a single measure of cyberchondria, the Cyberchondria Severity Scale.

CONCLUSIONS

Our review found a positive correlation between health anxiety and online health information seeking, and between health anxiety and cyberchondria. Further research should aim to explore the contexts for these associations as well as address the identified limitations of the extant literature.

Health anxiety and cyberchondria among Ege University health science students

It is common among health science students to incorrectly believe that they have contracted certain diseases they have recently studied. This can also be seen in the form of health anxiety and investigating health-related information via the internet. Health anxiety, cyberchondria and affecting factors are determined among health science students. The study was conducted at the faculties of Medicine, Pharmacy, Dentistry and Nursing in 2016-2017 with the participation of 874 students. The data were gathered using a questionnaire as well as health anxiety and cyberchondria severity scales. In the presence of a health problem, 14.2% of students seek health information via the internet. 83.7% use mobile phone to access the internet, ¼ of students conduct health scanning once a week or more. To 65.4%, internet information is correct at medium and above level. No statistically significant difference was found with respect to students' gender, high school, places they lived before, parents' education and scales' scores. The cyberchondria scores of students with health problems are higher in the whole scale and in "distress and mistrust of medical professional" subscales. As the frequency of scanning on the internet increases, the scores of cyberchondria also increase significantly. Medical students had significantly higher scores in "distress, excessiveness and reassurance" subscales. Male students' "mistrust of medical professional and compulsion" subscales scores were also higher. It was determined that the presence of the health problem was effective on the cyberchondria. Identification of somatoform problems like health anxiety and cyberchondria may help to regulate the education program.

Moving toward a metacognitive conceptualization of cyberchondria: Examining the contribution of metacognitive beliefs, beliefs about rituals, and stop signals

Cyberchondria refers to the repeated use of the Internet to search for health information that leads to negative consequences. The present set of studies examined the tenability of a proposed metacognitive conceptualization of cyberchondria that includes metacognitive beliefs about health-related thoughts, beliefs about rituals, and stop signals. The contribution of those variables to cyberchondria was examined among 330 undergraduate students from a U.S. university in Study 1 and 331 U.S. community respondents in Study 2. All participants reported using the Internet to search for health information. Across both studies, metacognitive beliefs, beliefs about rituals, and stop signals shared positive bivariate associations with cyberchondria and accounted for unique variance in cyberchondria scores in multivariate analyses. Beliefs about rituals and stop signals emerged as relatively specific to cyberchondria versus health anxiety in multivariate analyses. Results provide preliminary support for a metacognitive conceptualization of cyberchondria, with extensions of the present findings discussed.

Cyberchondria: Overlap with health anxiety and unique relations with impairment, quality of life, and service utilization

Cyberchondria refers to a clinical phenomenon in which repeated Internet searches regarding medical information result in excessive concerns about physical health. Cyberchondria is positively associated with symptoms of health anxiety, though it remains unclear as to whether cyberchondria poses a unique public burden. The current study replicated previous findings regarding the relationship between cyberchondria and health anxiety, and extended those findings to examine the extent to which health anxiety and cyberchondria may be differentially associated with public health outcomes, including impairment, quality of life, and service utilization. Community participants (N = 462) recruited via online crowdsourcing completed a battery of self-report questionnaires assessing cyberchondria, health anxiety, and measures of public health outcomes, including the WHOQOL and SDS. Bifactor latent variable modeling indicated that cyberchondria was closely related to, yet importantly distinct from, health anxiety. Moreover, when accounting for overlap with health anxiety, cyberchondria was associated with increased functional impairment and healthcare utilization. Results provide further support for the identification of cyberchondria as a distinct set of clinical symptoms that may pose a significant public health burden. Future research should determine ways in which to treat and/or prevent symptoms.

The Cyberchondria Severity Scale (CSS): German Validation and Development of a Short Form

PURPOSE

'Cyberchondria' describes a pattern of researching health information online motivated by distress or anxiety about health, which becomes excessive and in turn increases distress. The Cyberchondria Severity Scale (CSS) assesses this construct. The aims of the present study were to validate a German version of the CSS and to propose a short form.

METHOD

The CSS was translated and posted online. Inclusion criteria were fulfilled by n = 500 participants (age 29.1 ± 10.4 years, 73.6 % women). Item analyses, an exploratory factor analysis and correlations with health anxiety, somatic symptoms, health-care utilization and depression were calculated. A brief version with 15 items was developed (CSS-15) and validated in a second sample (n = 292; age 24.2 ± 4.1 years, 76.4 % women).

RESULTS

The internal consistency of the CSS was α = .93 and its split-half reliability α = .95. The mean item-total correlation was r itc = .51, the mean inter-item correlation r = .29 and the mean item difficulty p i = .36. The principal component analysis extracted five factors. The CSS score correlated highly with health anxiety and moderately with somatic symptoms and health-care utilization. The CSS-15 still had an internal consistency of α = .82 and the confirmatory factor analysis confirmed the five factors. The correlation coefficients with health-related measures were unaffected.

CONCLUSION

The German version of the CSS possesses very good psychometric characteristics, which were preserved in a short version. The factorial structure was replicated. The correlations with health anxiety and depression for both scales underscore their validity and clinical relevance.

Somatosensory amplification - An old construct from a new perspective

The paper reviews and summarizes the history and the development of somatosensory amplification, a construct that plays a substantial role in symptom reports. Although the association with negative affect has been supported by empirical findings, another key elements of the original concept (i.e. body hypervigilance and the tendency of focusing on mild body sensations) have never been appropriately addressed. Recent findings indicate that somatosensory amplification is connected with phenomena that do not necessarily include symptoms (e.g. modern health worries, or expectations of symptoms and medication side effects), and also with the perception of external threats. In conclusion, somatosensory amplification appears to refer to the intensification of perceived external and internal threats to the integrity of the body ("somatic threat amplification") rather than amplification of perceived or actual bodily events only. Practical implications of this new approach are also discussed.

Cyberchondria: Examining relations with problematic Internet use and metacognitive beliefs

Cyberchondria refers to the repeated use of the Internet to search for health-related information, which leads to negative consequences. This two-part study provides the first known examination of how cyberchondria relates to (a) problematic Internet use and (b) metacognitive beliefs. Participants were U.S. community adults who reported using the Internet to search for health-related information (Study 1: N = 337, Study 2: N = 260). In Study 1, cyberchondria shared a strong association with problematic Internet use, and that association was unaccounted for by age, gender, current reported medical status, negative affect, or health anxiety. In Study 2, cyberchondria was found to share moderate to strong associations with metacognitive beliefs. The association between cyberchondria and metacognitive beliefs about the uncontrollability of thoughts remained intact after accounting for the Study 1 covariates, as well as anxiety sensitivity and intolerance of uncertainty. Neither anxiety sensitivity nor intolerance of uncertainty shared unique associations with cyberchondria. These results provide a preliminary indication that a metacognitive conceptualization of problematic Internet use may be applicable to cyberchondria.

The curious case of cyberchondria: A longitudinal study on the reciprocal relationship between health anxiety and online health information seeking

The current study is the first to longitudinally investigate the reciprocal relationship between online health information seeking and health anxiety, i.e., cyberchondria. Expectations were that health anxious individuals who go online to find health information, experience an increase in health anxiety, which in turn will reinforce online seeking. A 4-wave longitudinal survey study among 5322 respondents aged 16-93 was conducted. Our results showed that individuals who are more health anxious than others, search online for health information more. Moreover, the results provided initial evidence for the expected reciprocal relationship between health anxiety and online health information seeking in respondents with non-clinical levels of health anxiety at the start of the study. However, this reciprocal relationship could not be found in a subsample of clinically health anxious individuals. Although for these individuals online health information seeking did not seem to exacerbate health anxiety levels, it might still serve as a maintaining factor of clinical health anxiety.

Cross-cultural adaptation of the Cyberchondria Severity Scale for Brazilian Portuguese

Abstract Introduction: The internet has proven to be a valuable resource for self-care, allowing access to information and promoting interaction between professionals, caregivers, users of health care services and people interested in health information. However, recurring searches are often related to excessive health anxiety and a phenomenon known as cyberchondria can have impacts on physical and mental health. Within this background, a Cyberchondria Severity Scale has been developed to differentiate healthy and unhealthy behavior in internet searches for health information, based on the following criteria: compulsion, distress, excesses, and trust and distrust of health professionals. Objective: To conduct cross-cultural adaptation of the Cyberchondria Severity Scale for Brazilian Portuguese, because of the lack of an appropriate instrument for Brazil. Methods: This study was authorized by the original author of the scale. The process was divided into the following four steps: 1) initial translation, 2) back-translation, 3) development of a synthesized version, and 4) experimental application. Results: Translation into Brazilian Portuguese required some idiomatic expressions to be adapted. In some cases, words were not literally translated from English into Portuguese. Only items 7, 8, 12, 23 and 27 were altered, as a means of both conforming to proper grammar conventions and achieving easy comprehension. The items were rewritten without loss of the original content. Conclusion: This paper presents a translated version of the Cyberchondria Severity Scale that has been semantically adapted for the Brazilian population, providing a basis for future studies in this area, which should in turn contribute to improved understanding of the cyberchondria phenomenon in this population.

Does cyberchondria overlap with health anxiety and obsessive-compulsive symptoms? An examination of latent structure and scale interrelations

Searching for medical information online is a widespread activity that increases distress for many individuals. Researchers have speculated that this phenomenon, referred to as cyberchondria, overlaps substantially with both health anxiety and obsessive-compulsive symptoms. This study sought to examine: (1) the distinguishability of cyberchondria from health anxiety and obsessive-compulsive symptoms and (2) the components of health anxiety and obsessive-compulsive symptoms that cluster most strongly with cyberchondria. The sample consisted of community adults in the United States with no current reported medical problems (N=375). Results from confirmatory factor analyses (CFAs) support the idea that cyberchondria is distinct from, yet related to, health anxiety and obsessive-compulsive symptoms. Results from zero-order correlations and regression analyses suggest that cyberchondria clusters with the affective (health worry) component of health anxiety. Regression results diverged from prior findings, as obsessive-compulsive symptoms did not share associations with cyberchondria after accounting for negative affect and health anxiety. The present results indicate that cyberchondria is possibly discernible from both health anxiety and obsessive-compulsive symptoms, while also providing insight into areas of potential overlap.

Relationships between cyberchondria and obsessive-compulsive symptom dimensions

Researchers have recently begun to investigate a vicious cycle of escalating physical health concerns and online medical information seeking coined "cyberchondria". Research has shown that cyberchondria is strongly associated with health anxiety (HA), but there is a dearth of work investigating the potential relationships between cyberchondria and other anxiety-related pathologies. One such condition is obsessive-compulsive disorder (OCD), which could theoretically be related to cyberchondria given the physical health relevant focus of certain types of OC symptoms. The current study sought to investigate the potential relationship between cyberchondria OCD across OC symptom dimensions. Community participants (N=468) were recruited via online crowdsourcing to complete a battery of self-report questionnaires including cyberchondria and OC measures. Structural equation modeling revealed significant unique associations between both contamination/washing and responsibility for harm/checking symptoms, and cyberchondria, such that greater cyberchondria was associated with greater OC symptoms after controlling for HA and trait negative affect. These results suggest that similar to proposed models of cyberchondria and HA, cyberchondria could potentially play a role in the development/maintenance of two dimensions of OC symptoms, or vice versa. Future work will need to determine the causal nature of these relationships or whether they are simply co-occurring phenomena.

Anxiety sensitivity and intolerance of uncertainty as potential risk factors for cyberchondria: A replication and extension examining dimensions of each construct

BACKGROUND

Preliminary findings suggest that anxiety sensitivity (AS) and intolerance of uncertainty (IU) may confer vulnerability for cyberchondria, defined as repeated internet searches for medical information that exacerbates health anxiety. Prior studies are limited because it remains unclear whether specific AS or IU dimensions differentially relate to certain cyberchondria dimensions.

METHODS

The present study examined associations among AS, IU, and cyberchondria dimensions using a sample of community adults (N = 578) located in the United States.

RESULTS

As predicted, physical AS and inhibitory IU were the only AS or IU dimensions to share unique associations with the distress cyberchondria dimension after controlling for the overlap among the AS dimensions, IU dimensions, and health anxiety. Cognitive AS and social AS unexpectedly evidenced unique associations with cyberchondria dimensions.

LIMITATIONS

The results are limited by the cross-sectional study design and use of a community, rather than clinical, sample.

CONCLUSIONS

This study provides evidence that specific AS and IU dimensions may confer vulnerability to certain cyberchondria dimensions. Further clarifying associations among AS, IU, and cyberchondria may lead to improvements in our conceptualization and, ultimately, treatment of cyberchondria.

Validation of the Cyberchondria Severity Scale (CSS): replication and extension with bifactor modeling

Internet help seeking behaviors are increasingly common. Despite the positives associated with technology, cyberchondria, or the process of increased anxiety in response to internet medical information seeking, is on the rise. The Cyberchondria Severity Scale (CSS) was recently developed to provide a valid measure of cyberchondria across multiple dimensions. The current study sought to extend previous work on the CSS factor structure by examining a bifactor model. Participants (N=526) from a community sample completed the CSS via online crowd sourcing. Results revealed that the bifactor model of the CSS provided superior fit to the data, suggesting that it is useful to conceptualize the CSS as containing a General Cyberchondria factor that is orthogonal to its subfactors. Similar to previous work, the CSS Mistrust factor does not appear to be necessary to this construct. Finally, results revealed unique relations between General and Specific Cyberchondria factors with lower-order health anxiety dimensions.

Anxiety sensitivity and intolerance of uncertainty as potential risk factors for cyberchondria

BACKGROUND

Online medical information seeking has become an increasingly common behavior. Despite the benefits of easily accessible medical information on the Internet, researchers have identified a vicious cycle of increased physical health concerns and online medical information seeking known as "cyberchondria". Despite proposed theoretical models of cyberchondria, there is a dearth of research investigating risk factors for the development of cyberchondria. Two potential risk factors are anxiety sensitivity (AS) and intolerance of uncertainty (IU).

METHODS

The current study investigated the relationships among AS, IU, and cyberchondria in a large community sample. Participants (N=526) completed self-report questionnaires via online crowdsourcing.

RESULTS

Structural equation models utilizing latent variables revealed a significant unique positive relationship between AS, as well as the IU Inhibitory lower-order factor, and cyberchondria, controlling for the effects of health anxiety. Additionally, results revealed a significant unique relationship between the IU Inhibitory factor and mistrust of medical professionals, a proposed cyberchondria-relevant construct.

LIMITATIONS

The cross-sectional data in the current study do not offer a true test of AS and IU as risk factors. However, establishing these unique relationships is an important step forward in the literature.

CONCLUSIONS

The results of the current study suggest the potential importance of both AS and IU in the development of cyberchondria. Future research is needed to establish the temporal precedence of elevated AS and/or IU to determine if they are true risk factors or simply correlates of cyberchondria.

The Cyberchondria Severity Scale (CSS): an examination of structure and relations with health anxiety in a community sample

McElroy and Shevlin (2014) developed the 33-item Cyberchondria Severity Scale (CSS) to allow for a multidimensional assessment of cyberchondria (compulsion, distress, excessiveness, reassurance, and mistrust of medical professional). The present study evaluated psychometric properties of the CSS, including its factor structure, internal consistency, convergent validity, and incremental validity, using a large sample of community adults located in the United States (N=539). Results from a confirmatory factor analysis (CFA) supported the adequacy of the five-factor structure of the CSS. However, results from a higher-order CFA indicated that the mistrust of medical professional factor does not assess the same construct as the other factors of the CSS. The CSS scales evidenced adequate internal consistency and significantly correlated with health anxiety. The distress, excessiveness, and mistrust of medical professional scales correlated significantly more strongly with health anxiety than obsessive-compulsive symptoms and these three scales were the only CSS scales to share unique variance with health anxiety. Implications of these results for future research are discussed.
