ABSTRACT
Two online studies (Total N = 331) tested the hypothesis that individual differences in self-control and responses to uncertainty would predict adherence to Centers for Disease Control and Prevention (CDC, 2020a) guidelines, reported stockpiling, and intentions to engage in hedonic behavior in response to the COVID-19 pandemic. Trait self-control (b = 0.27, p = .015), desire for self-control (Study 1: b = 0.28, p = .001; Study 2: b = 0.27, p = .005), and cognitive uncertainty (b = 0.73, p < .001) predicted more CDC adherence. State self-control (Study 1: b = -0.15, p = .012; Study 2: b = -0.26, p < .001) predicted less stockpiling, whereas emotional uncertainty (b = 0.56, p < .001) and cognitive uncertainty (b = 0.61, p < .001) predicted more stockpiling. State self-control (b = -0.18, p = .003) predicted less hedonic behavior, whereas desire for self-control (b = 0.42, p < .001) and emotional uncertainty (b = 0.26, p = .018) predicted more hedonic behavior. Study 2 (pre-registered) also found that emotional uncertainty predicted more stockpiling and hedonic behavior for participants low in state self-control (stockpiling: b = -0.31, p < .001; hedonic behavior: b = 0.28, p = .025), but not for participants high in state self-control (stockpiling: b = 0.03, p = .795; hedonic behavior: b = -0.24, p = .066). These findings provide evidence that some forms of self-control and uncertainty influenced compliance with behavioral recommendations during the COVID-19 pandemic.
