This epidemiological investigation assesses the prevalence of depression and anxiety symptoms during the COVID-19 pandemic. A total of 10,061 adults participated in the study. Symptoms of depression and anxiety were two to three times higher compared to pre-pandemic samples. Those who predominantly socially distanced themselves revealed substantially higher symptoms than their counterparts. Females, ethnic and sexual orientation minorities, younger adults, unemployed individuals, and those with a psychiatric diagnosis reported higher prevalence of psychological symptoms. Worry about prolonged duration of physical distancing protocols and frustration of autonomy was associated with elevation in symptoms of depression and anxiety. Increased competence to deal with the crisis was associated with less adverse symptoms. Physical exercise, experiencing nature, and distraction with activities were associated with less depressive symptoms, but not anxiety. The extent of information access about the pandemic was associated with reduced anxiety symptoms. Furthermore, adherence to mitigation protocols was investigated. Younger adults and males reported lowest adherence. Altruistic attitudes, in addition to mandatory as opposed to voluntary adherence was associated with higher adherence. Worrying about significant others’ health was associated with higher, while worry about duration of pandemic protocols was associated with lower adherence rates.
