Coronavirus disease 2019 (COVID-19) is a new communicable disease caused by the new strains of severe acute respiratory syndrome coronavirus, SARS-CoV-2 [1] . The first outbreak reported was in December 2019, in Wuhan, China, as pneumonia of unknown etiology linked to a seafood market exposure [2] . On January 30, the World Health Organization (WHO) declared the outbreak as a Public Health Emergency of International Concern (PHEIC) and a pandemic On March 11 [3] .
The first case reported In Saudi Arabia was on March 7; at that time, increasing numbers were seen all over the world, with the majority of confirmed cases currently in the united states, brazil, and Russia [4] . After reporting the first case in Saudi Arabia, the government response was swift and immediate, started by launching a social media campaign encouraging people to stay at home and to follow the ministry of health instructions [5] . On March 23, a lockdown was imposed on Mecca, Medina, and Riyadh with travel restrictions all over the country, and within the next ten days, the curfew was extended to 24-Hour [6] .
The fast climbing of cases of COVID-19 all over the world and the rapid changes in people daily living have left people alarmed and frightened. Historically, there have been multiple outbreaks over the years, such as the SARS epidemic, when moderate to severe post-traumatic-stress symptoms were reported in the highly affected areas [7] . During the swine flu (influenza A H1N1) outbreak, a study showed that 9.6% and 32.9% of the general population were either very or moderately worried about the possibility of being infected, respectively [8] . Ebola, MERS, and SARS epidemics all showed an impact on mental health that includes depression, and even substance abuse has been reported [9] . During the MERS outbreak in Jeddah, western Saudi Arabia, a survey reported a significant association between the level of anxiety and avoiding behaviors [10] . In the current pandemic, a recent study carried out in china concerning COVID-19 psychological impact, revealed that 53.8% of respondents are showing moderate to severe psychological impact, 16 .5% and 28.8% reported moderate to high depressive or anxiety symptoms respectfully, and 8.1% moderate to high levels of stress were reported [11] . Anxiety and depression symptoms showed no decline four weeks after the COVID-19 pandemic [12] .
To the best of our knowledge, there are no published studies assessing the general population response to the emerging coronavirus infections in Saudi Arabia. Therefore, this study aims to measure the degree of psychological responses resulted from the COVID-19 pandemic on Saudi Arabia's general population.
J o u r n a l P r e -p r o o f As described in the study methodology, statistical analysis was carried out using IBM SPSS Statistics for Windows, version 22 .0 (IBM Corp., Armonk, NY, USA). The data were cleaned, sorted, and processed prior to commencement of analyses. The survey's answers fields were designed to be mandatory to be filled before proceeding to the next section, options such as "None" or "I don't know" were provided when necessary in order to proceed and minimize missed data. Descriptive analyses were conducted for sociodemographic characteristics, health status/service utilization variables, symptom profile, contact history, knowledge and concerns, and precautionary measures. The results of these analyses were presented using frequencies and percentages for categorical variables and means and standard deviations for continuous variables using the total sample (n = 1160) as the base. The psychological burden of the COVID-19 pandemic was measured using scores on the IES-R and the three subscales of the DASS; results presented in means and standard deviation. Univariate analyses to determine the presence and strength of associations between individual variables and scores on each of the four scales (IES-R, DASS-stress, DASS-anxiety, and DASS-depression) were carried out using linear regressions. All tests of associations were carried out at a level of significance of < 0.05 and 95% confidence Interval.
With a range of 0 to 88, the average score of the participants on the revised impact of event scale (IES-R) questionnaire was 20.9 ± 15.7. More than half of the participants (59.7%) had normal scores on the IES-R, but 16.6% had scores in the mild range, and 17.9% classified as severe. On the DASS, 70.2% had normal scores on the stress subscale, 70.1% on the anxiety subscale, and 59.1% on the depression subscale. Severe symptoms of stress were experienced by 13.7%, which is similar to the 13.9% who experienced severe symptoms of anxiety and 16.4% who experienced severe symptoms of depression. 
The majority of the participants in this study were females (63.9%), between the ages of 31 and 40 years (23%), have at least a bachelor's degree (61.2%), married (54.2%), and employed (35.0%; Table 2 ). Most of the participants had gross family incomes of at least 5,000 SAR up to 14,999 SAR. Also, the majority lived in a villa (58.4%) and lived with six or more people in the same household (57.2%). Only a small proportion did work in a medical field (11.7%), but more of them had family members who worked in the medical field (27.9%).
The female gender was associated with higher scores in the IES-R (B: 5.46, 95% CI: 3.61 to 7.31) and all three subscales of the DASS with odds of between 1.65 and 2.63. With respect to age, those between 18 and 30 years are more susceptible to adverse mental health outcomes with 7.75 times odds of having higher scores on the IES-R (95% CI: 2.53 to 12.98) and all the three subscales of the DASS. Participants with only a high school degree were more likely to have higher scores on all scales: IES-R and the three subscales of the DASS. Employment was only significantly associated with lower scores on the IES-R (B = -5.72, 95% CI: -10.68 to -0.77). Being a student as significantly associated with higher scores across all three subscales of the DASS with B coefficients ranging from 3.69 to 6.71.
Earning less than 5,000 SAR was significantly associated with higher scores on the IES-R (B = 4.00, 95% CI: 0.11-7.90) and the depression subscale of the DASS (B = 2.85, 95% CI: 0.21 to 5.49). However, working in the medical field or having a family member who works in the field was associated with higher scores on the DASS. When participants worked in the medical field, they were more likely to have higher scores on the stress (B = 4.33, 95% CI 2.35 to 6.31) and J o u r n a l P r e -p r o o f depression (B = 2.77, 95% CI 0.88 to 4.67) subscales of the DASS. When they had family members who worked in the medical field, they were more likely to have higher scores across all three subscales of the DASS (stress: B = 1.77, 95% CI 0.34 to 3.20; anxiety: B = 1.17, 95% CI 0.11 to 2.24; and depression: B = 2.04, 95% CI 0.68 to 3.40).

The physical health status of the majority of the respondents at the time of the study was self-reported to be good or very good (86.6%; Table 3 ). However, a sizeable proportion had a chronic disease (17.3%), and 10.5% had been diagnosed to have a psychiatric disorder at the time of data collection. Within the two weeks period preceding data collection, 16.8% had visited hospitals for different reasons, and only 0.8% of the total population needed to be admitted for serious illness.
Thirty-three respondents were tested for COVID-19 (2.8%), and 12 respondents (1.0%) were quarantined within the previous 14 days.
Across the three subscales of the DASS and the IES-R, having a poor health status was found to be significantly associated with high scores. Participants with poor or very poor health were several times more likely than those with good health to have poor psychological health with a B coefficient of 15.10 on the IES-R (95% CI: 9.37-20.84), 14.95 on the stress subscale of the DASS (95% CI: 10.94 to 18.95), 12.18 on the anxiety subscale of the DASS (95% CI: 9.23 to 15.12), and 13.83 on the depression subscale of the DASS (95% CI: 10.02-17.64). Having a chronic disease was only significantly associated with lower scores on the stress subscale of the DASS (with B coefficient of -2.08 and 95% CI of -3.77 to -0.39). Having a psychiatric disorder was significantly associated with higher scores on all the scales (IES-R: B = 8.43, 95% CI 5.53 to 11.33; DASS-stress, B = 8.83, 95% CI 6.80 to 10.85; DASS-anxiety: B = 8.27, 95% CI 6.78 to 9.75; and DASSdepression: B = 9.83, 95% CI 7.92 to 11.75).
Within the immediate period before the study, some of the participants had experienced a wide range of symptoms that have been associated with COVID-19 (Table 3) . These most reported symptoms were headache (23.8%), and sore throat (11.1%). It is important to note that 60.8% of the participants indicated that they had not experienced any of these symptoms within the same period. However, participants who had experienced any of dizziness, difficulty breathing, muscle pains, headache, nasal congestion, sore throat, and diarrhea were significantly more likely to have high scores on the IES and all three subscales of the DASS. Not experiencing any of the above-listed symptoms was significantly associated with lower scores on all the scales: IES-R at a 95% confidence interval (Table 3) .
J o u r n a l P r e -p r o o f 
Participants were tested to know their level of knowledge, confidence, and satisfaction with regards to the COVID-19 pandemic ( Table 4 ). The majority of them believe that transmission of the disease is through exposure to air droplets released by an infected person via sneezing and coughing and direct contact (96.6%). Similarly, the majority of them were very (30.6%) or extremely (44.4%) confident about the effectiveness of the methods used in diagnosing the disease; and a total of 78.7% were very/extremely satisfied with the amount of information available on the disease.
On probing further to understand the sources of information for the participants, the majority sourced their information from the Saudi Ministry of Health (87.2%), the World Health Organization (40.9%), and non-official social media applications and platforms such as WhatsApp, Twitter, YouTube, etc. (40.3%). Across all the information sources, participants who sourced their information from the World Health Organization were significantly more likely to have worse scores across both the IES-R (B = 2.60, 95% CI 0.78 to 4.43) and DASS stress (B = 3.06, 95% CI 1.77 to 4.35), anxiety (B = 1.37, 95% CI 0.40 to 2.33), and depression (B = 2.38, 95% CI 1.15 to 3.62) subscales. Relying on local news was significantly associated with lower scores on the DASS-anxiety (B = -1.06, 95% CI -2.10 to -0.02). All other information sources had no significant associations with the scores on either the IES-R or DASS.
Only 1.5% of the total population have had a relative diagnosed with COVID- 19 . When asked about their perceivability of contracting SARS-CoV-2 during the current outbreak, the majority believed they had lower chances of being infected with 41.6% saying it was not likely and another 23.9% believed it was only slightly likely. However, if infected, the majority believed their chances of recovering was very likely (33.1%) or extremely likely (43.4%). Having relatives who have tested positive for COVID-19 or being diagnosed with the disease had no significant impact on the scores on the IES-R and DASS. Participants who believed they have a slight chance of recovering if they should contract COVID-19 were significantly more likely to have higher scores across all the scales -IES-R and DASS stress, anxiety, and depression. Similarly, those who believed they were very likely to have the disease were more likely to have higher scores across all the scales (IES-R: B = 9.81, 95% CI 5.80 to 13.83; DASS-stress: B = 9.41, 95% CI 6.60 to 12.22; DASS-anxiety: B = 6.90, 95% CI 4.80 to 9.00; and DASS-depression: B = 9.54, 95% CI 6.85 to 12.22) . Also, participants were asked what they thought about the statement: "I feel that there is much unnecessary worrying regarding COVID-19". The majority of them disagreed that there is much unnecessary worrying regarding the disease (71.5%). However, those who strongly disagreed were significantly more likely to have higher scores on the stress subscale of the DASS (B = 2.67, 95% CI: 0.17-5.16).
J o u r n a l P r e -p r o o f J o u r n a l P r e -p r o o f
Some of the participants had had indirect contact with someone diagnosed with COVID-19 (0.5%) or direct contact with someone diagnosed with the disease (0.2%). Having direct or indirect contact with a diagnosed case of COVID-19 had no significant association with IES-R and DASS scores (Table 5 ). About 1.7% of the participants had had direct contact with someone suspected to have COVID-19, and this group appeared to have significantly high scores on the anxiety (B = 4.39, 95% CI 0.74 to 8.05) and depression (B = 6.27, 95% CI 1.58 to 10.96) subscales of the DASS. The majority of the participants did not have any contact history suggestive of contact with the infectious agent of COVID-19 (81.4%), and this set of people were found to have significantly lower scores on the IES-R (B = -2.99, 95% CI -5.30 to -0.68).
The majority of the participants had maintained strict self-isolation, not going out at all as a result of the coronavirus outbreak (56.4%, Table 5 ). Another 38.1% were indoors for more than 12 hours per day. However, the amount of time spent indoors (intensity of self-isolation) had no significant impact on scores on the IES-R and DASS. Probing into how participants had protected themselves from COVID-19 over the previous 14 days, the majority of them had been washing and disinfecting their hands regularly (89.7%). Other measures adopted include avoiding handshakes (67.0%), distancing themselves physically from others for at least one meter (58.9%), avoiding the sharing of utensils during meals (23.4%), and using face masks even when without any symptoms (16.9%). Also, 7.2% of the respondents said they had not done anything specific to protect themselves.
With regards to the psychological impact of these precautionary measures, those who washed and disinfected their hands frequently were significantly associated with lower scores on the depression subscale of the DASS (B = -2.43, 95% CI -4.44 to -0.42). Those who maintained at least one meter of social distancing were also significantly associated with lower scores on the stress (B = -1.49, 95% CI -2.79 to -0.19) and anxiety (B = -1.53, 95% CI -2.50 to -0.57) subscales of the DASS. 
This study aimed to assess the psychological impact of COVID-19 pandemic on the general population of Saudi Arabia; Our results suggest that concerning the early psychological impact of the general public,23.6% of respondents reported moderate or severe psychological impact of the outbreak and severe symptoms of stress were experienced by 13.7%, which is similar to the 13.9% who experienced severe symptoms of anxiety and 16.4% who experienced severe symptoms of depression. Our findings are in line with previous findings of a study conducted during the pandemic in Iran where it reported the level of severe anxiety to be 19.1% and another study in Spain where it reported the level depression, stress, anxiety to be 9.9%, 7.8%, 11.6% respectively [18] [19] . Contrary to the findings of our study, a recently published study in china where 53.8% reported their psychological impact of the outbreak moderate or severe, 16.5% and 28% reported depressive and anxiety symptoms ranged from moderate to severe, while 8.1% reported moderate to severe stress levels [11] . The lower prevalence in our study could be attributed to that in the early days of the outbreak; only a few cases have been reported in Saudi Arabia with the majority of cases are imported from abroad and the lower perceived likelihood of being infected during the current outbreak as we found in this study.
Among participants, 11.7 % worked in a medical field, and 27.9% had a family member working in a medical field; those participants had a higher score in the stress and anxiety and depression subscale, and this is in agreement with previous studies published recently and during MERS outbreak in Saudi Arabia and studies conducted during the current COVID-19 pandemic in Singapore and India [20] [21] [22] [23] .In addition to that, we found that females and students had higher scores across all DASS subscales, as was consistent with a previous study done in China [11] , this could be attributed to the uncertainty of used methods in continuing the educational process after closing up the campuses and schools. Furthermore, earning less than 5,000 SAR was significantly associated with higher scores on the IES-R the depression subscale, the economic impact of the pandemic cannot be overlooked which had left families with lower-income fearing of losing their jobs and homes, to mitigate this damage the Saudi government has released several initiatives, including offering free health care for everybody and financial incentives for the private sector [24] .
Respondents with poor self-rated health status found to have a greater psychological impact and poorer mental health compared to the majority of the respondents (86.6%) who view their health status to be (good or very good). Moreover, the most reported physical symptom were headaches, sore throat, muscle pain, symptomatic respondents had poorer psychological status when compared to non-symptomatic. Similarly, this was seen in the study carried out in Mainland, China, during the COVID-19 pandemic [11] . This may be explained by the fact that the novel coronavirus found to be more aggressive on people with comorbidities and below-optimal health status, which may result in more psychological burden and excessive worry [25] . People with mental disorders are also more susceptible to stress compared to the general public, and such outbreaks can provoke relapses or even worsen the already existing psychological disorder [26] . In our study, participants with reported mental disorders (10.5%) showed high scores on all DASS and IER-S scales. Our finding is in alignment with a recent study comparing people with and without psychiatric illnesses during the current COVID 19 pandemic where people with psychiatric illnesses were more likely to exhibit higher levels of PTSD, depression, anxiety, and stress. [27] This finding stresses the need to support this particular population, especially during the lockdown where access to psychiatric services is difficult through expanding the telepsychiatry services and home delivery of medications. Besides that,(17.3%) of the participants reported having a chronic disease, which was associated with lower scores on the stress subscale, which is inconsistent with the study conducted in the Mainland, China [11] . Within the two weeks preceding data collection, 16.8% had visited hospitals for different reasons, and they score high on anxiety subscale. Respondents who have been quarantined and tested for COVID-19 show no significant association with any of the subscales, and this might be explained by the assurance they received from the negative results of the screening and showing no symptoms during the quarantine period.
Overall, the majority of the respondents (95%) showed an excellent level of knowledge on the mode of transmission of the coronavirus (contact, droplet), which indicates a satisfactory level (85%) of information about the disease being delivered to the general population. Those levels showed better rates compared to the study conducted in Mainland, China [11] . The overwhelming majority of respondents indicated some level of confidence in available testing options. However, those with lesser degrees of confidence (low, moderate) were likely to be associated with a higher level of depression, anxiety, stress, and psychological impact, as reported by Wang et al. [11] . The current study shows the general population confidence in local health authorities as shown to be the dominant source of information on COVID-19 related matters (88%), followed by WHO and non-official news circulating social media platforms like WhatsApp and Twitter, It worth noticing that our samples population was approached using those platform, however, the non-official sources were not the primary source of information, This shows the importance of delivering timely evidence-based J o u r n a l P r e -p r o o f information by the official health authorities through All platforms. Respondents demonstrated high levels of application of evidence-based preventive measures, i.e., hand hygiene and social distancing, which indicate a sufficient level of information as discussed earlier.
Moreover, respondents display a high level of optimism in recovery in case they have the infection, which is consistent with their age group and the fact that 80% of the infected population will have mild disease [3] . Similar to the finding of AlNajjar et al., an increase in perceived susceptibility to the infection was associated with higher psychological impact [28] . Besides that, only 5 % reported very high susceptibility of contracting the disease compared to 13 % amid MERS infection in Jeddah, SA [28] .
Hand hygiene and other Precautionary measures were found to have protective psychological effects, which is consistent with the finding reported in China during the earlier stages of the pandemic [11] . On the contrary, those who avoided sharing utensils showed a high IES-R score; this could be attributed to the direct relation of utensils to the primary mode of transmission., Also using a protective mask regardless of the presence of the symptoms was associated with worse IES-R score in contrary to findings by a recent study where they found that mask-wearing was associated with lower levels of anxiety and depression. [12] When comparing our results to a previous study during the outbreak of influenza A (H1N1) in Saudi Arabia, about 61% of the population reported that they did not take mild or minimal precautions to prevent infection [29] . There is an increase in using precautionary measures right now, which can be attributed to social media campaigns that are focused on boosting public awareness and emphasizing the importance of wearing masks to prevent spreading of the virus in the community [30] ; moreover, the Saudi government adopted new regulations mandating masks wearing in public places [31] The findings of this study emphasize the need for governments to adopt new strategies to improve psychological services for community and individuals level by focusing on delivering accurate, evidence-based information to minimize the effect of fake news and to identify and support high-risk groups especially those with preexisting mental illness by expanding telepsychiatry services, promoting mental wellness and psychological interventions nationwide.
Limitations of the study include the time of data collection where the outbreak in Saudi Arabia was at its early stage with reported cases less than two thousand, which may have underestimated the psychological impact of the outbreak. For the time-sensitivity of the outbreak and with a curfew in place, we adopted a snowballing sampling strategy, which is a non-probability sampling technique. However, we assumed a study design effect of 3 in the sample calculation to compensate for the used sampling technique. Oversampling of particular regions (e.g., Qassim region), where we approached the initial sampled group, and the limitations to reach less educated people and non-social media users led to less generalizable results. Also, As a limitation of the study design, the survey provides only a snapshot of psychological responses at a particular point in time, and a longitudinal study is required to provide information on whether the observed impact will last for longer periods. The self-reported psychological impact, anxiety, depression, and stress may not adequately represent the mental health status assessed in an interview; thus, for the outcome to be determined, prospective studies are necessary to provide more accurate data to support the need for focused public mental health strategies. Lastly, the number of respondents who have been quarantined, tested for COVID-19, and had a contact history with infected persons was minimal, and our result could not be generalized on them. Despite all the above limitations, our study provides information about the immediate psychological responses of Saudi Arabia's general population on the COVID-19 pandemic. It covers many factors that can influence mental health and provides a broader vision of the issue for future researches. Our results give an idea about the magnitude of the psychological burden on the community during such outbreaks and offer ways to minimize the impact.
Throughout the early stage COVID-19 pandemic in Saudi Arabia, the results showed that one-fourth of the general population experienced moderate to severe psychological impact. Working in the medical field, females, students, and having a mental disorder are all associated with high scores in stress, anxiety, and depression subscales. Following specific precautionary measures appeared to have a protective effect on the individual's mental health. Our findings can be used to construct a psychological intervention directed toward the general and vulnerable population and to implement public mental health strategies in combination with pandemic response efforts in early stages of the event.
