Loss of resources and gambling during the COVID-19 pandemic: a three-wave longitudinal study.

This study is based on the Conservation of Resources theory and investigates the impact of the COVID-19 pandemic and associated resource loss on gambling behaviour among Polish gamblers. The study surveyed 585 individuals engaged in land-based gambling before the pandemic. Participants completed computer-assisted web interviews, responding to questions regarding land-based and online gambling frequencies, the Problem Gambling Severity Index, and the Inventory of Loss of Resources in Pandemics. The findings revealed significant shifts in gambling behaviour due to pandemic-related restrictions. Land-based gambling declined during lockdowns and the third wave of the study, while online gambling surged as gamblers transitioned from land-based venues. Gamblers tended to return to land-based options as restrictions eased. Over consecutive waves, participants reported decreasing resource loss levels. Significantly, resource loss was influenced by gambling frequency rather than vice versa. Both types of gambling experienced parallel declines at the beginning of the pandemic, which subsided as the new situation became normalised. Players engaging more in gambling experienced more significant resource losses during the pandemic. Those with more resources at the pandemic's onset adapted more readily, whereas individuals with limited resources faced resource loss. Conclusions Even with stable gambling levels, heavy gamblers at baseline were at higher risk for issues. The dynamics between resource loss and gambling and problem gambling supported the resource loss spiral concept.
