HIGHLIGHTS This study examined the early psychological correlates associated with the COVID-19 pandemic and lockdown in an older adult sample. Regardless of mental status, depressive and avoidant style were the most prevalent in this older adult sample. Interventions need to be tailored to alleviate dysfunctional coping strategies and their progression to mental illness.

Aim To provide a population-based characterization of sociodemographic and clinical risk and protective factors associated with consumption of alcohol, tobacco, or both as a coping strategy in a sample of the Spanish general population during the early phase of the COVID-19 pandemic. Methods Cross-sectional study based on an online snowball recruiting questionnaire. The survey consisted of an ad hoc questionnaire comprising clinical and sociodemographic information and the Spanish versions of the Depression, Anxiety, and Stress Scale (DASS-21) and the Impact of Event Scale (IES). Results The final sample included 21,207 individuals [mean age (SD) = 39.7 (14.0); females: 14,768 (69.6%)]. Up to 2,867 (13.5%) of participants reported using alcohol, 2,545 (12%) tobacco and 1,384 (6.5%) both substances as a strategy to cope with the pandemic. Sex-related factors were associated with alcohol consumption as a coping strategy [female, OR=0.600, p<0.001]. However, education level, work status, and income played different roles depending on the substance used to cope. Having a current mental disorder was associated only with tobacco consumption as a coping strategy [OR=1.391, p<0.001]. Finally, sex differences were also identified. Conclusions Sociodemographic, clinical, and psychological factors were associated with consumption of alcohol, tobacco, or both as a coping method for the COVID-19 pandemic and lockdown. Our findings may help develop specific intervention programs reflecting sex differences, which could minimize negative long-term outcomes of substance use after this pandemic.
