Addiction-related behavioral problems increase during the first six months of the Covid-19 pandemic
Abstract Background and aims: In this study we aimed to assess multiple addiction-related behaviours simultaneously for an extended period of time during the Covid-19 pandemic and their relation to distress. Methods: Data were collected every three days from Amazon’s MTurk between 26.03.2020 and 02.10.2020 in cohorts of 25 participants resulting in a total sample of 1430 US adults (60% men, mean age 36.6 years, SD = 11). General distress and Covid-19 related fear were assessed as well as self-reported frequency of eight potentially addictive behaviours: shopping (compulsive buying), alcohol, smoking, legal substances, illegal substances, gambling, gaming and overeating. Results: We found a positive relationship between time and the frequency of each self-reported addiction-related behaviour (𝜏 = 0.15 - 0.23, all p<0.001), and their frequency is linearly related to the intensity of (Covid-19-related and general) distress (𝜏 = 0.12 - 0.28, all p<0.001). Most popular activities were gaming and compulsive buying, and the relative frequency of the behaviours remained about the same during the data collection period. Discussion: It is possible that people seek substitutes when other coping mechanisms (e.g. social recreation) are hindered depending on their level of distress. Conclusion: Given the evidence for the increasing frequency of addiction-related excessive behaviours and their relevance to distress, special attention needs to be paid to reduce potential harmful effects of maladaptive coping during and after this demanding period.
