Previous studies showed that depression and anxiety were highly prevalent in pandemics, and tended to appear in comorbidity among SARS survivors (Mak et al., 2009 ). Therefore, these psychiatric problems and their comorbidity may be another result of the novel coronavirus outbreak. In many countries, the age benchmark of 60 was used to demark those at high-risk for COVID-19 complications (Murthy et al., 2020) . Thus, our first goal was to compare psychiatric symptoms of depression, anxiety and their comorbidity between those at low-and high-risk for COVID-19 complications. Our second goal was to address the psychiatric effects of social-distancing (Mizumoto and Chowell, 2020) , a policy adopted in the absence of specific medical treatments. A central potential outcome of such social-distancing policy is loneliness, defined as a discrepancy between desired and perceived social relationships (Jeste et al., 2020) . Loneliness is linked with a myriad of deleterious physical and mental consequences (e.g., Heinrich and Gullone, 2006) . To the best of our knowledge, the present study is among the first to evaluate COVID-19 related psychiatric symptoms of depression and anxiety, and their comorbidity in a Western society (Israel), where restrictive social-distancing has been employed. Using the Qualtrics web-based public platform, we collected data (March 15-April 1 st ) across Israel using a snowball design, via social-media platforms. On the last day of data collection, 6902 people in Israel tested positive for COVID-19, 241 recovered and twenty-five had died. Participants (n=1059, average age=46.21±16.49, range 18-100) electronically signed an informed consent. Most were women (n=798, 75.2%), married/cohabitating (n=762, 71.8%) with tertiary-education (n=805, 76.1%). Participants completed a demographic questionnaire, including age, gender, marital-status, education, diagnosis of chronic medical conditions related to increased risk of death due to COVID-19 complications [yes/no] and self-rated health. Exposure levels to six COVID-19 related risk situations (e.g., self-isolation, knowing someone in isolation) and change in eleven pandemic related behaviors (e.g., hand washing) were also queried. In addition, participants were asked to report how the COVID-19 outbreak affected loneliness levels (3- Age was negatively correlated with PHQ-9 and GAD-7 (r=-.25, r=-.21, respectively, p's<0.000), and loneliness was positively correlated with PHQ-9 and GAD-7 (r=.34, r=.29, respectively, p's <0.000). Finally, PHQ-9 and GAD-7 were strongly correlated (r=.74, p<0.000). Using the accepted cutoffs for PHQ-9 (≥10; n=153, 14.4%) and GAD-7 (≥10; n=201, 19.0%), we found that a higher percentage of participants younger than 60 reported symptoms above the cutoffs for both PHQ-9: ꭓ 2 (1058,1)=10.36, p<.005, and GAD-7: ꭓ 2 (1056,1)=28.75, p<.000. Further, a higher percentage of women reported symptoms above the PHQ-9, ꭓ 2 (1061,1)=4.89, p<.05, and GAD-7 cutoffs, ꭓ 2 (1059,1)=7.15, p<.01. Marital-status distribution did not co-vary with cutoff score distributions for both PHQ-9 and GAD-7. A higher percentage of participants without academic education reported symptoms above the PHQ-9 cutoff, ꭓ 2 (1058,1)=9.07, p<.005, but not for the GAD-7 cutoffs. Finally, no differences were found between diagnosis of chronic medical conditions (related to increased risk of death due to COVID-19) and cutoffs for PHQ-9 and GAD-7, (ꭓ 2 (1043,1)=.54, p=.46; ꭓ 2 (1041,1)=2.65, p=.11, respectively). When examining comorbidity, 41(3.9%) participants reported suffering only from PHQ-9 symptoms above the cutoff, 89 (8.4%) suffering only from GAD-7 symptoms above the cutoff and 112 (10.4%) displayed symptoms above the cutoff for both disorders. Univariate and multivariate logistic regression analyses showed that after entering demographics, health-related factors, exposure to COVID-19 related events, behavioral change and loneliness, loneliness was the most prominent risk factor for depression and anxiety (PHQ-9: OR=1.62, 95%CI: 1.35-1.94; GAD-7: OR=1.61, 95%CI: 1.36-1.90). Moreover, the results showed (see Table 1 ) that relative to those with low loneliness, those with high loneliness were 82% more susceptible to suffer from depression-anxiety comorbidity due to the coronavirus outbreak (OR=1.82, 95% CI: 1.47-2.27). The first main finding is somewhat counterintuitive, indicating that old age as an actual risk for COVID-19 complications was unrelated with depression and anxiety. Likewise, neither the suffering from chronic medical conditions (related to increased risk of death due to nor exposure to COVID-19 related risk situations were related to higher risk for depressive and anxiety symptoms. Critically, for age, this was even reversed, namely, adults above 60 who are at higher risk for COVID-19 complications, actually displayed greater resilience to psychiatric disorders associated with the COVID-19 crisis. Such results can be viewed in light of older adults typically displaying lower reactivity to stress, exercising more effective emotional regulation, having greater experience with being alone and with life-threatening medical situations, and thus were perhaps less sensitive (Losada-Baltar et al., 2020). The second main finding reveals that loneliness, due to the social-distancing policy, was the main risk-factor for depression, anxiety and especially their comorbidity. In line with previous studies linking loneliness with a range of deleterious physiological and psychiatric outcomes (Heinrich and Gullone, 2006) , the results underscore that loneliness at such a time (regardless of the socialdistancing policy) bears a notable psychiatric toll. Accordingly, policy makers and mental health practitioners need to stress the importance of safe social interactions (Jeste et al., 2020) . Although this preliminary study is limited by its cross-sectional and self-report design, which may affect its generalizability, and despite the fact that individuals' psychiatric history was not assessed, it offers pioneering insight into negative psychiatric outcomes linked with the COVID-19 pandemic. Further, this study is based on a relatively large sample and was conducted during the pandemic, thereby carrying important information in terms of the special psychiatric attention warranted to the more vulnerable younger-adults, who are at lower risk of COVID-19 complications.
