The Dark Triad of Personality’s Relationship with Compliance towards COVID-19 Pandemic Recommendations along with Anxiety and Depressive Symptoms in Polish Citizens

The outbreak of the COVID-19 pandemic forced everyone to comply with rules of a sanitary regime and social distancing on a daily basis. The aim of our research was to assess the differences in the levels of Dark Triad traits between people who obeyed and disobeyed the pandemic restrictions. Additionally, we considered the possible correlation between the Dark Triad and the intensity of symptoms of depression and anxiety. A total of 604 Polish participants, whose average age was 28.95 ± 11.27 years, completed an online survey which measured Dark Triad traits using the Polish version of the Dirty Dozen test. Anxiety and depression were assessed using the Hospital Anxiety and Depression Scale (HADS). The results revealed a possible relationship between personality traits and compliance with pandemic restrictions. Individuals with higher levels of psychopathy tended to disobey newly introduced rules. On the other hand, a higher level of subclinical narcissism might have contributed to a better civil compliance. The results showed a significant positive correlation between the intensity of the Dark Triad and the occurrence of depressive symptoms. Furthermore, narcissism was linked to anxiety symptoms. These results can contribute to a better understanding of behavioural patterns during the COVID-19 pandemic within the group of individuals who exhibit the Dark Triad traits. Our conclusions might help to identify individuals who are particularly vulnerable to mental health problems.


Introduction
The outbreak of the COVID-19 pandemic in 2020 forced many countries all over the world to combat the fast-spreading virus. The Polish authorities decided to introduce pandemic restrictions on an unprecedented scale (isolation, quarantine, social distancing, and the shutdown of many economic sectors). The priority was to reduce the spread of SARS-CoV-2 caused by people with symptoms of COVID-19 as well as by asymptomatic or pre-symptomatic individuals [1]. Anderson et al. claimed that the compliance of individuals with COVID-19 rules was crucial to control the course of the coronavirus pandemic [2]. This theory was considered most pertinent to western European countries. Citizens of those countries are used to many civil rights and liberties which are an essential part of their everyday existence. Many of them exhibit hostile attitudes towards pandemic restrictions. They took matters into their own hands to safeguard their civil liberties by disobeying the pandemic rules imposed by EU governments. This resistance could be observed in many countries all over the world and it took various forms. The characteristics of people who disobeyed pandemic restrictions have been a subject of many studies [3][4][5][6][7][8][9][10]. It is very important to examine and understand motives underlying this disobedience due to the fact that results of many studies have shown that the risk of infection sinks when individuals comply with depression, or anxiety [39,40] and therefore contribute to maintaining good mental health. However, the relationship between narcissism and depression is more complicated and depends on the type of narcissism [32,41,42], with some types (e.g., grandiose) being prone to negative emotions [42,43]. This study is an attempt to consider whether individuals who exhibit a high intensity of the Dark Triad traits might be one of the groups particularly vulnerable to mental health problems triggered by the pandemic. We still lack studies which could confirm or deny this hypothesis. Our current study is an attempt to fill in this gap.
The aim of this study was to assess the differences in the Dark Triad of personality between people who obeyed and disobeyed pandemic restrictions and to analyse the relationship of its component traits with the severity of depressive and anxiety symptoms. In our current research, we tried to consider the threat which people with Dark Triad traits could pose on public health and security. But furthermore, we wanted to indicate that people with a high intensity of Dark Triad traits could be in danger of suffering from negative mental health consequences themselves. This approach lets us adapt a more holistic view on the Dark Triad of personality.

Data and Participants
The Dark Triad of personality, anxiety, and depression were measured using the convenience sampling method (sampling via social media). For this purpose, an online survey was created, consisting of a sociodemographic questionnaire and psychological scales-the Dirty Dozen and the Hospital Anxiety and Depression Scale (HADS). The survey was created using Google Forms software and shared via social media networks (Facebook and Instagram) from the 10th of November until 2 December 2020. On 27 October 2020, Polish authorities introduced lockdown type measures for the second time in Poland. They lasted for the whole of November and December. During this time, citizens were obliged to stay at least 1.5 m away from other people and to wear a face mask as well as to follow hand hygiene recommendations and restrict their movement. A total of 604 Polish citizens participated in the study-468 women (77.50%) and 136 men (22.50%), aged 28.95 ± 11.27 years. Respondents did not receive any award for their participation in our research. Our survey did not allow participants to provide incomplete responses. Moreover, the answers provided by each one of the respondents were analysed separately, and their accuracy was checked by the authors of this study. Due to this, all responses were valid and could be included in the study. Table 1 presents sociodemographic characteristics of the study group.

The Dirty Dozen
Jonason and Webster's questionnaire [44] is well-known and widely used as a scientific research tool for assessing the intensity of the Dark Triad of personality. It consists of 12 questions. The intensity of each trait (psychopathy, narcissism, and Machiavellianism) is assessed using 4 questions, and the respondents provide their answers on a 5-point scale (from 1 to 5). The results can be considered either as a whole or divided into subscales of psychopathy, narcissism, and Machiavellianism. The minimum score possible to obtain in each subscale is 4 (12 for whole), while the maximum is 20 (60 for whole). The Polish version of the questionnaire was created in 2016 by Czarna [45] by adapting Jonason and Webster's original version. The validation analysis confirmed that the measure met the criteria of psychometric usefulness with good reliability ranging between 0.67 and 0.79 [45], making it a reliable research tool. In our study, the Cronbach's alpha coefficient for the whole test was estimated at 0.85.

The Hospital Anxiety and Depression Scale (HADS)
The scale by Zigmond and Snaith [46] is commonly used to assess anxiety and depressive symptoms for healthy individuals as well as for people who suffer from somatic disorders. The test consists of a total of 14 questions which are divided into two subscales: the anxiety subscale (HADS-A) and the depression subscale (HADS-D). Each subscale contains 7 questions which assess respondents' moods over the past week. The answers are given on a 4-point scale (from 0 to 3). The scores obtained on each subscale are summed (the minimum score possible to each subscale is 0, while the maximum is 21). A meta-analysis by Bjelland et al. [47] has shown that scores ≥ 8 are most often "an optimal cut-off score for both HADS-A and HADS-D". Adhering to this conclusion, we defined all scores ≥ 8 on the HADS-A or HADS-D scales as significant levels of depressive or anxiety symptoms. The anxiety and depressive symptom severity scores are analysed as follows [48]: 0-7 pointsno anxiety or depression, 8-10-mild anxiety or depression, 11-14-moderate anxiety or depression, 15-21-severe anxiety or depression. The high sensitivity and specificity of the subscales (about 0.80) [47] make the scale a reliable screening tool. In our study, the Cronbach's alpha coefficient for the whole test was 0.80. In order to divide our respondents into two groups, we asked them 3 yes-or-no questions: "Do you follow hand hygiene recommendations?"; "Do you follow social distancing recommendations?"; "Did you go out less often during the COVID-19 pandemic?" The responses to each of the three questions were analysed separately, and we performed a triple division of our respondents. Participants who answered "yes" were considered as those adhering to one of the three recommendations, and those who answered "no" were considered as those who did not adhere.

Data Analysis
The analysis of the collected data was performed using the computer programs Excel 2016 and Statistica version 13.3. For the measures used, Cronbach's alpha coefficients in the study sample were determined. The normality of the distributions was assessed based on the Shapiro-Wilk test. We calculated the mean levels of Dark Triad considered both as a whole and in its components, as well as levels of depressive and anxiety symptoms among those who adhered to a specific recommendation and those who did not. We compared the results from both groups for each of the three recommendations. Due to the size of the groups being compared (each group > 100), the t-test was used [49] to test the significance of intergroup differences, assuming the statistical significance level p ≤ 0.05. We analysed the correlations between the Dark Triad of Personality, its components and the symptoms of anxiety and depression in the respondents. Correlation matrices were prepared using Spearman's rank correlation coefficient, where p < 0.05 was taken as the level of statistical significance. To complete the results, we added an assessment of the severity of anxiety and depressive symptoms among our participants.

Ethics
The study was approved by the university Bioethics Committee, and it adhered to the Declaration of Helsinki. Each participant was informed about the anonymity and voluntariness of participation in the study and had the opportunity to discontinue participation in the study at any time. Table 2 presents descriptive statistics of the variables. We included both women and men in the statistical analyses. For control purposes, a study of the significance of differences between gender groups was performed. The differences turned out to be typical. Men presented a significantly higher intensity of the overall Dark Triad score (28.235 vs. 24.620; p < 0.000) and its components-psychopathy (9.507 vs. 7.765; p < 0.000) and Machiavellianism (8.485 vs. 7.186; p < 0.000), while women presented a higher intensity of anxiety (9.278 vs. 7.794; p < 0.000). The respondents were divided into groups according to whether they adhered to the recommendation to stay at home or not (Table 3). Those adhering to the recommendation to reduce the frequency of leaving their homes exhibited different intensity of psychopathy and narcissism compared to those not adhering to this recommendation. A higher level of psychopathy was exhibited by the group opposed to this recommendation. Interestingly, a higher level of narcissism was found in the group of respondents declaring a reduction in the frequency of leaving home.

Results
Participants were also divided into groups based on whether or not they complied with hand hygiene recommendations (Table 4). Individuals who did not follow the recommendation to frequently disinfect their hands had a significantly higher level of psychopathy. On the other hand, those who adhered to this recommendation presented higher intensity of narcissism.  Lastly, the respondents were divided into those who adhered to social distancing restriction and those who did not (Table 5). Again, those declaring adherence to such restriction exhibited significantly different levels of psychopathy to those declaring nonadherence to the restriction. The opponents of social distancing had a higher average intensity of psychopathy. We also took into consideration the relationships between the components of the Dark Triad of personality and the severity of the symptoms of anxiety and depression in the studied group ( Table 6). The study revealed a significant positive correlation between the intensity of the Dark Triad, its components, and the severity of depressive symptoms. Narcissism also correlated positively with anxiety. Significant correlations were also observed between the Dark Triad components: at a moderate level between psychopathy and Machiavellianism and narcissism and at a high level between narcissism and Machiavellianism. Finally, the severity of anxiety symptoms in the study group exhibited a moderate, positive correlation to the severity of depressive symptoms. Interesting results were also obtained in terms of depressive and anxiety symptoms in the entire study group (Figure 1). The mean severity of anxiety among the study group was 8.929 ± 3.710 points. Significant levels of anxiety symptoms were observed in 379 individuals (mild-189, moderate-139, severe-51) which equals 26% of the study group. In the study group, the mean severity of depressive symptoms was 5.512 ± 3.388 points. Significant levels of depressive symptoms were observed in 157 individuals (mild-98, moderate-53, severe-6) which equals 63% of the study group. Interesting results were also obtained in terms of depressive and anxiety symptoms in the entire study group (Figure 1). The mean severity of anxiety among the study group was 8.929 ± 3.710 points. Significant levels of anxiety symptoms were observed in 379 individuals (mild-189, moderate-139, severe-51) which equals 26% of the study group. In the study group, the mean severity of depressive symptoms was 5.512 ± 3.388 points. Significant levels of depressive symptoms were observed in 157 individuals (mild-98, moderate-53, severe-6) which equals 63% of the study group.

Discussion
In our study, we examined differences in the Dark Triad traits among two groups of respondents-individuals who adhered to recommendations and individuals who did not. In order to draw reliable conclusions about the relationship between Dark Triad and behavioural tendencies, it is necessary to consider each trait of this cluster individually. The intensities of subclinical narcissism and psychopathy seem to have exhibited opposite effects on the behaviours of individuals during the pandemic. Narcissism can encourage compliance towards pandemic restrictions (e.g., hand hygiene recommendations, social distancing). On the other hand, individuals with higher levels of psychopathy are more likely to disobey those recommendations. The results obtained in our study did not show any significant correlation between Machiavellianism and civil compliance. Nonetheless, other authors claimed that this kind of connection indeed exists and that all of the three Dark Triad traits are linked to disobedience towards pandemic restrictions [4,8,9].

The intensities of subclinical narcissism and psychopathy seem to have exhibited opposite effects on the behaviours of individuals during the pandemic. Narcissism can encourage compliance towards pandemic restrictions (e.g., hand hygiene recommendations, social distancing). On the other hand, individuals with higher levels of psychopathy are more likely to disobey those recommendations. The results obtained in our study did not show any significant correlation between Machiavellianism and civil compliance. Nonetheless, other authors claimed that this kind of connection indeed exists and that all of the three Dark Triad traits are linked to disobedience towards pandemic restrictions [4,8,9].
Bearing in mind that each one of the Dark Triad traits is actually a complex set of various characteristics in itself, the specific similarities and differences between psychopathy and narcissism must be considered. Narcissism as well as psychopathy is linked to extraversion and openness [15]. Previous studies showed that individuals with higher extraversion tended to have difficulties with obeying social distancing rules. On the other hand, this trait did not impact compliance with the hand hygiene recommendations [7]. The observations made by Zajenkowski et al. [4] showed a negative correlation between extraversion and compliance towards pandemic restrictions. These observations contradict the conclusions drawn by Aschwanden et al. [6]-here higher extraversion was associated with higher obedience. Despite common features shared by narcissism and psychopathy, the key role in their impact on one's behaviour is in all probability played by the specific interactions between the different traits which, as a whole, form the psychopathic and narcissistic tendency.
The behaviour of individuals who score higher on narcissism is based on external sources of motivation and their actions are usually aimed at building a positive social image of themselves. This makes them tend towards prosocial behaviours [25]. It is very possible that the adoption by narcissistic individuals of a certain behavioural pattern is caused by the intensified need of building and maintaining a positive social image (e.g., being an upstanding citizen who obeys pandemic restrictions). Vulnerable narcissism is linked to a significant tendency to feel shame [23] and therefore an inability to take criticism from other members of society (e.g., being criticised due to disobedience towards pandemic restrictions).
In contrast to narcissism, psychopathy is linked to low conscientiousness [15], which can also affect one's ability to follow the new everyday duties of the strict pandemic rules. Furthermore, low neuroticism can cause diminished ability to experience emotions like anxiety or shame [36,50] and is specific to individuals who exhibit a higher level of subclinical psychopathy [15]. Therefore, low neuroticism can predispose these individuals to ignore the necessity of following safety measures during the pandemic [5]. Psychopathic individuals are also more immune to criticism (because of their low ability to feel guilt or shame [50]) and can therefore easily break social norms by disobeying newly introduced rules. The diminished ability to fear the possible consequences of getting a SARS-CoV-2 infection can also intensify the tendency to disobey.
Another difference between psychopathy and narcissism is the tendency to exhibit antisocial behaviours [14,16,17]. Positive correlation with this trait is significantly stronger in psychopathy than in narcissism [16]. Some authors claim that narcissism is not at all connected with a tendency to exhibit socially undesirable behaviours [51]. The particular characteristics of psychopathic personalities which are linked to antisocial behaviours, immorality, and a lack of empathy, can additionally encourage disobedience towards pandemic restrictions.
Our study showed that the impact which the Dark Triad might have on civil compliance cannot be considered as purely negative. Its impact seems to be dualistic: narcissism can be a trait which encourages compliance while psychopathy can be linked-to disobedience.
In the current study, we also decided to examine the relationship between the Dark Triad and anxiety and depression within society during the pandemic. Depressive symptoms were present in 26% of respondents among the study group, and 63% experienced a significant severity of anxiety symptoms during the pandemic. These scores might have been influenced by the negative impact of stress factors linked to the COVID-19 pandemic. Before the pandemic, the prevalence of mental disorders in which anxiety and depressive symptoms were present in Polish society was determined as follows: major depression-3%, minor depression-0.4%, and anxiety disorders such as panic attacks-6.2%, generalised anxiety disorder-1.1%, social phobias-1.4%, specific phobias-3.4% [52]. However, among students (who made up about 45% of our respondents), the prevalence of depression was higher [53]. Due to the limitations of our study (selection of a sample, the HADS, which cannot be used for epidemiological studies), our results are not representative of the general population and should be interpreted in the context of the characteristics of our study group. Due to the high number of scientific studies which examine mental health during the pandemic, we decided to focus on the relationship between the Dark Triad traits and depressive and anxiety symptoms.
According to our best knowledge, this study is the first to focus on the relationship between the Dark Triad traits and symptoms of anxiety and depression during the pandemic. The results obtained showed that the Dark Triad as well as all of its individual components correlated positively with depressive symptoms. Mood disorders are a result of emotional dysregulation [54], which is commonly exhibited by narcissistic, psychopathic, and Machiavellian individuals [55,56]. Additionally, psychopathy and Machiavellianism correlate with a reluctance to seek social support even during difficult, stressful life situations [57]. Attempting to endure life's difficulties without seeking from other members of society can have a negative impact on mental well-being [58]. Psychopathy and Machiavellianism are linked to a deficiency in task-oriented coping skills, especially in terms of dealing with stressful situations [57]. Difficulties in solving problems may lead to negative mental health consequences. Machiavellianism correlates positively with anhedonia (which can one of the symptoms of depression) and alexithymia [33], and this relationship might explain the occurrence of mood disorders. Although previous studies claimed that narcissism can prevent from depression [39] our study showed a positive correlation between depressive symptoms and narcissism. Narcissism is associated with emotional instability [55] and correlates negatively with mental toughness [42]. Furthermore, vulnerable narcissism is bound up with negative emotions (such as stress [42]) and decreased mood [55]. Therefore, this type of narcissism is more strongly linked to depressive disorders [43]. We think it might be true that among our study group this type of narcissistic tendency was particularly common. We would like to suggest that future studies on the correlation between mental well-being and the Dark Triad traits should use methods which distinguish between different types of narcissism.
In our study, subclinical narcissism was positively correlated with anxiety symptoms. Psychopathy and Machiavellianism were not shown to have had any statistically significant correlations with levels of anxiety. During the COVID-19 pandemic individuals with higher levels of narcissism have been observed to develop a negative affect [10] which underlies emotional disorders such as anxiety [54]. With regard to narcissism, the vulnerable type seems in this case to be the most relevant. It can be characterised by an inability to cope with failure and criticism, low self-esteem [23], and reduced psychological resilience [42], which can intensify the feeling of insecurity and lead to emotional dysregulation [55]. Additionally, vulnerable narcissism is associated with high neuroticism [59]. Individuals who exhibit these traits will be more prone to experience emotional tension [60]. Neurotic individuals may tend to follow the news about the development of the pandemic very carefully and get strongly engaged in searching for the latest information and updates [61], which may cause a significant increase in perceived anxiety and depression [62]. This behaviour can pose a serious threat to the mental well-being of these individuals.
Some previous studies also showed the negative impact of the Dark Triad traits on mental health [24,32,35], and our research confirmed these results. However, the relationship between the Dark Triad of personality and mental health is not fully resolved issue. Different authors claim that a high level of narcissism may also have some positive influence [39,40] on the mental health of individuals, which was not confirmed by our study. Therefore, we believe that this issue still needs further research in order to draw reliable conclusions.

Limitations
The present study has some limitations which future research could aim at improving. Firstly, the method of convenience sampling we used is flawed, and it does not ensure a random selection of a sample. The study was carried out on social media networks. Therefore, our sample consists only of individuals who have internet access and an account on those social media networks. For these reasons the results of our study may not be relevant for the whole population. Furthermore, convenience sampling does not provide total control over the age and gender of respondents. The cause of this limitation is that within our respondents were 28 people aged 16 and 17. Due to the fact that this age is not an obstacle in measuring levels of personality traits, we decided to keep their answers in our study. Secondly, the Dirty Dozen test does not distinguish between different subtypes of narcissism, psychopathy, and Machiavellianism. Thirdly, the questions used to assess civil compliance with pandemic restrictions were originally established by the authors of this study. The answers given were based on self-report methods and they should not be considered as an objective evaluation of the participants' actions. Fourthly, in our analysis, we considered a whole study group without dividing it according to age and gender. The fact that there was a big difference between the number of male and female participants, as well as that young adults predominated, might have biased the results. Therefore, we would like to suggest that the results of our study are most relevant for young, well-educated adults, especially women. Future studies should consider the age, gender, and education diversity of the study group.

1.
Individuals with a high intensity of psychopathy may exhibit reluctance to comply with the rules of the sanitary regime.

2.
Subclinical narcissism may be linked to a need of adjustment to newly introduced rules.

3.
Individuals with high intensity of Dark Triad traits may require special psychological and psychiatric care during this health crisis because they might be more vulnerable to depressive symptoms.

4.
Subclinical narcissism correlates positively with anxiety symptoms.
