Cyberchondria severity and quality of life among Lebanese adults: the mediating role of fear of COVID-19, depression, anxiety, stress and obsessive–compulsive behavior—a structural equation model approach

Background This study highlights the significant association between cyberchondria and quality of life among the Lebanese population in the time of COVID-19. The aim was to assess the association between cyberchondria and quality of life (QOL) of Lebanese community during the COVID-19 pandemic and assess the mediating effect of fear of COVID-19, depression, anxiety, stress and Yale-Brown Obsessive–Compulsive Scale in this association. Methods This cross-sectional study was carried out between December 2020 and January 2021, during the COVID-19 pandemic. A total of 449 persons participated in this study by filling the online questionnaire. Structural equation modeling (SEM) was performed to examine the structural relationship between cyberchondria severity, the mediator (anxiety, stress, depression, obsessive–compulsive disorder (OCD) and fear of COVID-19) and physical/mental QOL. Results Having a university level of education and older age were significantly associated with higher physical QOL scores, whereas higher obsession-compulsion disorder, higher stress and higher anxiety were significantly associated with lower physical QOL scores. Higher anxiety was significantly associated with lower mental QOL scores. The results of the SEM showed that stress, fear of COVID-19 and to a lesser limit OCD, mediated the association between cyberchondria severity and physical QOL, whereas anxiety, stress and fear of COVID-19 mediated the association between cyberchondria severity and mental QOL. Conclusion This research reported interesting results encouraging more exploration of cyberchondria and its association with quality of life during this unique period of the pandemic. However, this virus has altered the lives of individuals all across the world, and the consequences will last for a long time. Along with all of the steps done to stop the development of COVID-19 and improve physical outcomes, mental health requires immediate care. More research is needed to determine the coping techniques people are employing to deal with the pandemic.

psychological effects of such epidemics are pervasive and probably more severe. While fear has always been invoked by infectious diseases, and because of global access to information, this response has never been as widespread as it is with COVID-19 [2]. Therefore, at times of great instability, such as the COVID-19 pandemic, it is predicted that an increased number of cases of cyberchondria will occur [3]. By the appearance of the virus, media of all kinds were loaded with reports and analysis related to the causes and effects of the disease [4]. As a result, the internet has become an important global source of health information [2,4] since it provides formal access to high quality, enormous volume, current and appropriate health information [5]. In the United States, for example, 35% of people use the Internet to search for medical problems that they or someone else may have [4]. Likewise, a study in 2016 found that more than 50% of adults in the United Kingdom were seeking online health information [4]. Considering the steady rise in Internet penetration across the world and the amount of information posted online, these trends are kind of expected. However, increased time spent searching for health information has amplified the levels of anxiety, a phenomenon called "Cyberchondria" [4,6].
According to theoretical theories, a reinforcement cycle characterizes cyberchondria, in which an individual suffers increasing worry when accessing health information online, prompting them to seek reassurance regarding its accuracy. These attempts lead to a short-term drop in anxiety, which perpetuates the long-term cycle because anxiety reductions adversely promote information-seeking behaviors [7]. The reassurance-seeking model, which proposes that people with high levels of health anxiety participate in online health research to be comforted about their health concerns, was the first theoretical analysis of cyberchondria [8]. Because the structure of the Internet makes the outcome of reassurance seeking on the Internet entirely unpredictable, some people are reassured by what they find online, while others are not. Those who do not receive comfort or only receive partial reassurance and hence become more worried continue to use (online Health Research) OHR in an attempt to find reassurance [8]. The negative consequences of OHR, such as increased anxiety and discomfort, are linked to specific metacognitive beliefs. These beliefs could be about the Internet's ability to help people cope with healthrelated stress and worry (positive metacognitive beliefs), or they could be about the loss of control over OHR and a feeling that it is harmful (negative metacognitive beliefs) [8]. If negative metacognitive beliefs are more prevalent, OHR becomes a perceived threat, and OHR is viewed as stressful, obsessive, and out of control-a pattern known as "compulsive OHR" [8].
Cyberchondria has rarely been investigated as a factor capable of influencing one's quality of life (QOL). QOL is defined, by the World Health Organization (WHO), as "an individual's perception of their position in life in the context of the culture and value systems in which they live and in relation to their goals, expectations, standards and concerns" [9]. The COVID-19 pandemic has widely affected human's life in a relatively short period of time [10]. Lockdown periods forced by governments as safety measures to face this pandemic had negative impact on mental and psychosocial wellbeing, including but not limited to stress, negative emotions and impaired cognition [11]. People are confused how secure they are and how anxious they should be because of the unpredictability of the situation, leading to concerns and misunderstandings [12]. In this sense, the first negative factor that is likely to affect one's quality of life is the fear that arises as a result of COVID-19 [13]. Fear is one of the most basic human emotions, and it is crucial to humanity's evolutionary emotional continuity [14]. Individuals naturally became concerned about the COVID-19 because of the extremely high infection rate and relatively high mortality. Fear of contacting people who may be infected with COVID-19 has been reported, and this, unfortunately, may intensify the damage of the disease itself [15]. People tried to cope in a socially distancing context by engaging in activities that affirm social (e.g., communicating virtually online) in order to overcome perceived threats and contagion fear [16]. These behaviors may serve as coping mechanisms for people who are scared of getting the disease, improving their well-being and therefore their quality of life [16].
According to recent research, during pandemic times, there is a significant risk of seeing secondary effects in any area of society, and emotional and behavioral issues such as anxiety, fear, depression, internet addiction, substance addiction and more [13]. Despite the Internet's usefulness for easily accessing information and encouraging health behaviors, it has been shown that Internet health information searches may expose inexperienced users to possible harms due to self-diagnosis, self-treatment, and growing levels of anxiety about health leading to possible consequent symptoms of depression and distress [17,18]. Cyberchondria has been strongly associated with increased anxiety about health [19]. Extreme anxiety induces excessive online searching for one's health, and that is more closely linked to health anxiety disorder [20]. In contrast, another theory shows that cyberchondria is related to obsessive compulsive behavior [19]. The compulsive research on health information acquisition contributes to an unhealthy rise in health anxiety [20]. The causality of the association between online searches related to health and health anxiety can differ from person to person. Thus, in order to seek reassurance for their health, users encounter different coping strategies that in some times, cause more discomfort and raise health anxiety even more [20]. Since the syndrome is driven by anxiety regarding potential health conditions or symptoms, the perceived severity of the given situation may be expected to increase [3]. Despite the fact that COVID-19 is positioned as a stressor with broad implications for mental and physical health, individual stress experiences vary greatly. The process of stress and coping maintains this heterogeneity [21]. Person features and contextual realities naturally impact both appraisal and coping behaviors. In general, stressor evaluations are correlated with higher overall levels of stress and its mental health correlates, such as depression and anxiety, as more severe or threatening [21]. A recent study revealed that 1724 US physicians who spent a greater proportion of their workday treating patients with COVID-19 experienced greater symptoms of depression, anxiety, and PTSD [22].
Many studies have reported the association between the QOL, cyberchondria and the coronavirus pandemic [2,19,23]. The proposed association between the pandemic, cyberchondria and the quality of life is illustrated in Fig. 1. No previous studies assessed the mediating effect of fear of COVID-19, depression, anxiety, stress and obsession-compulsion disorders in the association of cyberchondria and QOL. In Lebanon, however, there has been no research taking the quality of life of the population with COVID-19 pandemic along with the presence the cyberchondria. For this purpose, the aim of this study was to assess the association between quality of life of Lebanese community during the COVID-19 and cyberchondria and evaluate the mediating effect of fear of COVID-19, depression, anxiety, stress and obsessioncompulsion disorders in this association.

Study design
This cross-sectional study was carried out between December 2020 and January 2021, during the COVID-19 pandemic when lockdown procedures were implemented at different instances, and the measures taken by the government used to change on regular basis according to the severity of COVID-19 situation; 449 persons participated in this study by filling the online questionnaire. The sample was selected using a snowball technique from the five governorates of Lebanon (Beirut, Bekaa, Mount Lebanon, South Lebanon and North Lebanon). Respondents were briefed about the topic, and the different aspects of the questionnaire before filling it out, while being assured of the anonymity of the response. Inclusion criteria included people above 18 years old living in Lebanon.
Excluded were those who refused to participate in the study.

Minimal sample size calculation
The G-power software calculated a minimal sample of 395, based on a 5% alpha error and a power of 80% and 10 factors to be entered in the linear regression models.

Questionnaire
The questionnaires sent to participants was in the Arabic language, which is the official language of Lebanon as well as the native language of all respondents. The questionnaire included a sociodemographic category, and a scale-based category regarding different factors, as follows:

Sociodemographic data
In this part of the questionnaire, participants were asked about their general sociodemographic data, including their age, educational level, marital status, number of children and information about house crowding index of the participants. The household crowding index was calculated by dividing the number of persons living in the house and the number of rooms in the house, excluding the bathroom and the kitchen [24].

Scale-based category
The following scales were used in the questionnaire: Cyberchondria severity scale The 12-item short version scale was developed from the original 33-item Cyberchondria Severity Scale (CSS) [25,26] to allow for a multidimensional assessment of cyberchondria (compulsion, distress, excessiveness, reassurance, without the mistrust of medical professional part). It is scored on a 5-point Likert type scale (ranging from '1 = never' to '5 = always').
The CSS items can be summed to form a total score. Higher scores indicate higher cyberchondria (Cronbach's alpha in this study = 0.919).

Quality of life short form-12 health survey (SF-12)
Validated in Lebanon [27], this instrument is composed of twelve items to assess physical and mental health. The scores of each of these two sections are ranged from "0" up to "100". Greater scores indicate a higher physical/mental quality of life [28]. (Cronbach's alpha in this study = 0.746 for both subscales).

Yale brown obsession compulsion scale (YBOCS)
The Yale-Brown Obsessive Compulsive Scale provides a specific measure of the severity of symptoms of obsessivecompulsive disorder that is not influenced by the type of obsessions or compulsions present. The scale is a 10-item scale, each item rated from 0 (no symptoms) to 4 (extreme symptoms) (total range 0-40), with higher scores indicating more severe obsessive compulsive symptoms [29] (Cronbach's alpha for the total scale in this study = 0.860).
The Arabic version of this scale has been previously used in a previous project [30].

Fear of COVID-19 scale (7 items)
The FCV-19S is a unidimensional scale that assesses the fear of COVID-19. The instrument comprises seven items (e.g., "My heart races or palpitates when I think about getting coronavirus-19") which are responded to on a 5-point Likert scale from 1 (strongly disagree) to 5 (strongly agree). The scores that can be obtained from the FCV-19S vary between 7 and 35, and higher scores indicate greater fear of COVID-19 [15] (Cronbach's alpha for the total scale in this study = 0.884).
The Arabic version of this scale has been previously used in a previous project [31].
Lebanese anxiety scale The LAS-10 is a 10-item scale used to screen for anxiety in the general Lebanese adult [32] and adolescent [33] populations. Questions 1-7 are scored on a 5-point Likert scale from 0 (not present) to 4 (very severe), while items 8-10 are graded on a 4-point Likert scale from 1 (never/almost never) to 4 (almost always) [32]. Higher scores indicate higher anxiety (Cronbach's alpha in this study = 0.928).

Montgomery and Asberg Depression Rating Scale
The Montgomery-Åsberg Depression Rating Scale (MADRS) [36], validated in Lebanon [37], is a ten-item diagnostic questionnaire which psychiatrists use to measure the severity of depressive episodes in patients with mood disorders. MADRS items are rated on a 0-6 continuum (0 = no abnormality, 6 = severe). Higher scores indicate higher depressive manifestations. (Cronbach's alpha for the total scale in this study = 0.889).

Translation procedure
A clinical psychologist performed the forward translation from English into Arabic for the cyberchondria scale. A professional medical writer verified this translation. The backward translation was performed by a second clinical psychologist, unaware of the scales' notions and fluent in Arabic [38]. The principal investigator matched the backtranslated English questionnaire with the original one to detect inconsistencies and solve discrepancies between the two versions [38].

Statistical analysis
The SPSS software version 25 was used for the statistical analysis. Three factor analyses were initiated to confirm the legitimacy of the construct of the cyberchondria severity, fear of COVID-19 and YBOCS scales in our sample. The Kaiser-Meyer-Olkin (KMO) value and the Bartlett's sphericity test were checked for sampling adequacy. The factors with Eigen values > 1 were kept. Reliability was checked using Cronbach's alpha for the total scales. The sample was normally distributed as verified by the skewness and kurtosis of the PCS QOL and MCS QOL scores, which varied between − 2 and + 2 [39]. These conditions consolidate the assumptions of normality in samples larger than 300 [40]. The Student t and ANOVA tests were used to compare two and three or more means respectively. Pearson correlation test was used to correlate two continuous variables. Linear regressions were conducted, taking the physical and mental QOL scores as dependent variables. Independent variables entered in the multivariable analyses and mediation models were those that showed a p < 0.2 in the bivariate analysis. Significance was set at a p < 0.05. The SPSS AMOS software v.24 was used to conduct the structural equation modeling of the association between cyberchondria severity and physical/mental quality of life, taking different mediators into account (anxiety, stress, depression, obsessive-compulsive disorder and fear of COVID-19). Multiple indices of goodness-of-fit were described: the Relative Chi-square (χ 2 /df) (cut-off values: < 2-5), the Root Mean Square Error of Approximation (RMSEA) (close and acceptable fit are considered for values < 0.05 and < 0.11 respectively), the Tucker Lewis Index (TLI) and the Comparative Fit Index (CFI) (acceptable values are ≥ 0.90) [41,42].

Sociodemographic and other characteristics of the participants
A total of 449 participants out of 590 (76.10%) approached agreed to enroll in this study. The mean age of the sample was 24.34 ± 8.22 years, with 70.6% females. The mean cyberchondria severity score was 15.91 ± 9.64, whereas the mean physical and mental QOL scores were 38.98 ± 7.44 and 33.88 ± 8.45 respectively. Table 1 includes more details about the sample.

Factor analyses
The results of the factor analyses of the cyberchondria severity scale (  Table 2.

Bivariate analysis
Higher means physical and mental QOL scores were significantly found in those with a university level of Fear of COVID-19 score 15.64 ± 6.14 education compared to the other levels (Table 3). Higher anxiety, depression, stress, cyberchondria severity, obsession-compulsion and fear of COVID-19 were significantly associated with lower physical QOL scores.
Moreover, higher anxiety, depression, cyberchondria severity and fear of COVID-19 were significantly associated with lower mental QOL scores (Table 4).

Multivariable analysis
Having a university level of education compared to complementary or less (B = 2.53), and older age (B = 0.09) were significantly associated with higher physical QOL scores, whereas higher obsession-compulsion disorder (higher YBOCS scores) (B = − 0.23), higher stress (B = − 0.24) and higher anxiety (B = − 0.16) were significantly associated with lower physical QOL scores ( Table 5, Model 1). Higher anxiety (B = − 0.38) was significantly associated with lower mental QOL scores (Table 5, Model 2).

Structural equation modeling
The model tested during the structural equation modeling is summarized in Fig. 2.
The fit indices of each SEM are summarized in Table 6, whereas the coefficients with standard errors and p-values of the direct effects of variables on each other are summarized in Table 7 (physical QOL) and Table 8 (mental QOL) respectively. Stress, fear of COVID-19 and to a lesser limit OCD, mediated the association between cyberchondria severity and physical QOL, whereas anxiety, stress and fear of COVID-19 mediated the association between cyberchondria severity and mental QOL.

Discussion
This study demonstrated that higher obsession-compulsion disorder, higher stress and higher anxiety were significantly associated with lower physical QOL scores. Higher anxiety was significantly associated with lower mental QOL scores.
In this study, we found that high level of education was associated with high physical quality of life, corroborating the findings of a previous study [43]. Individuals who have completed higher education expand their chances to secure a career. In general, higher levels of educational attainment are related to better job opportunities and higher income, thereby having a positive impact on the quality of life of an individual [44].
In addition, older age was significantly associated with high levels of physical QOL. Results from previous   research about this association, are consistent; while a previous study showed that younger age had a negative impact on quality of life [45], another research showed that higher physical QOL were reported in the group aged 79-90 [46]. A possible reason is that age offers opportunities to develop resilience due to exposure over time to various and distinct stressors, resulting in improved emotional regulation and decreased symptoms of anxiety and depression [45]. We found that obsession-compulsion disorder, stress, and anxiety were significantly associated with lower physical QOL. A previous study found that all aspects of QOL are substantially impaired in individuals with Obsession Compulsion Disorder (OCD) and associated with the severity of the disorder [47]. Given the significant impact of OCD on patients' quality of life and the high frequencies of mental comorbidities, the current COVID-19 epidemic poses a special threat to OCD patients because of the increased disability caused by an increase in the frequency of obsessions and compulsions [47]. Furthermore, a previous study reported that stressful life events have an adverse effect on physical QOL [48]. An earlier study found that anxiety and stress were among the most common symptoms seen during the COVID pandemic [49,50]. Increased rates of stress and anxiety can be caused by the existence of uncertainty about the disease, reduced contact between individuals, and temporary restrictions of rights and freedoms due to lockdowns [51].
For the mental QOL, we found that high anxiety was associated with low mental QOL. During the COVID-19 epidemic, a recent study looked at the prevalence and determinants of anxiety symptoms, found that 41% of the sample reported mild symptoms of anxiety whereas 23% revealed severe anxiety symptoms [45]. Key aspects of anxiety included financial issues, personal health concerns, satisfaction with the current state of QOL and current health levels [45]. Another study found that the population is at risk of experiencing anxiety because of the high rate of mortality, insecurity of resources and food, experience of infected people, which may lead to  certain adverse mental health issues [52]. In fact, the pandemic has likely affected mental health in a number of ways, particularly with widespread social isolation resulting from required safety measures. Social isolation and loneliness led to both poor mental and physical health and high levels of anxiety [53]. We found that stress, fear of COVID-19 and to a lesser limit OCD, mediated the association between cyberchondria severity and physical QOL, whereas anxiety, stress and fear of COVID-19 mediated the association between cyberchondria severity and mental QOL. Wellbeing and life satisfaction have been adversely impacted by the new pandemic of COVID-19 [16]. The findings of a latest study found that there was a marked rise in pandemic issues and major behavioral changes [54]. Those behavioral changes increase the sense of restricted freedom, psychological distress and community anxiety. Therefore, the situation's unpredictability leaves people unsure about how secure they are and how concerned they should be, raising fears of the virus [54]. Studies have also shown that since the COVID-19 pandemic, the use of the internet and social networking sites for stress reduction, has increased [54]. Another symptom encountered is that prolonged internet search triggers COVID-19 fears at high levels, leading to severe health problems [54]. Indeed, a large part of the literature considers the role of disease event-related fears as predictors or mediators of QOL indicators [16]. People, like in every other pandemic situation, are first and foremost afraid of their lives, followed by the fear of losing their belongings. As the fear grows stronger, depression develops, and both fear and sadness are linked to different types of anxiety [55]. Although fears can adversely impact the QOL, it can also encourage people to reduce healththreatening behaviors [16]. In addition, the exacerbation of obsessive-compulsive behavior has been well-documented during past outbreaks. Nonetheless, the current COVID-19 epidemic has shown that obsessive-compulsive behavior has a significant effect on quality of life   [47]. Moreover, a finding consistent with ours is that cyberchondria's impact during COVID-19 was significantly mediated by anxiety [54]. 28% of the participants in an Indian study were moderate to extremely severely anxious [56]. People with elevated anxiety may assume that their feelings and symptoms are harmful. Following what they have read on the internet, they begin over-searching and worrying about their health. As a result, by looking online for appropriate medical information to minimize their harmful feelings, they try to find the source of these feelings [54]. For this purpose, exposure to social media and prolonged internet searching was associated with significant increase in anxiety symptoms [2].
This study highlights the significant association between cyberchondria and quality of life among the Lebanese population in the time of COVID-19. To our knowledge, no previous research has looked into a direct link between cyberchondria and quality of life; however, it could be mediated by other factors including depression, anxiety, or mental health issues as found in this study. Further studies are needed in order to better understanding the mechanism between cyberchondria and QOL. Thus, by shedding the lights on the findings of the research, we can assume that social support is crucial in reducing the negative effects of stress, anxiety, and fear, as well as promoting adaptation and, as a result, enhancing QOL during these hard times. A follow-up study evaluating how this population is reacting to the future trajectory of the COVID-19 pandemic, assessing the long-term impacts of the pandemic and investigating resources and resilience factors is much needed in order to cope better. This study has some limitations. The data's cross-sectional nature limits the ability to pull causal conclusions. The use of a self-administered questionnaire and the under or over-estimation of a question by a participant, poses a risk for information bias. There is also a risk of selection bias, given the nature of the sample based on which the study was conducted. Since the sample is small, further studies with larger sample are required in order to better assess the associations in this study. Some scales are not validated in Lebanon, thus, results should be interpreted with caution. Residual confounding bias is also possible since not all factors associated with QOL were considered in this study.

Conclusion
This research reported interesting results encouraging more exploration of cyberchondria and its association with quality of life during this unique period of the pandemic. This study adds useful information to the literature and shows similar results to recent studies found worldwide. However, this virus has altered the lives of individuals all across the world, and its consequences will last for a long time. Along with all of the steps done to stop the development of COVID-19 and improve physical outcomes, mental health requires immediate care. More research is needed to determine the coping techniques people are employing to deal with the pandemic. In addition, qualitative research could lead to a better understanding of the coronavirus's impact on people's physical and mental health.
