Trait self-construal, inclusion of others in the self and self-control predict stay-at-home adherence during COVID-19

To combat the global COVID-19 crisis, governments and health organizations rely on collective cooperation among every ordinary individual to adhere to non-pharmaceutical interventions (NPIs), such physical distancing which includes, as examined in our study, staying at home. Thus, we ask the question: do individual differences in how individuals see themselves as connected to or separated from others (i.e., independent vs. interdependent self-construal) predict their stay-at-home adherence? In an online study (N = 358; 47.1% female, M(age) = 40.48; 74.02% White), we measured trait self-construal, inclusion of others in the self (IOS), self-control and likelihood to stay-at-home in various scenarios. Results revealed a significant indirect, sequential effect of self-construal on stay-at-home adherence via IOS and self-control. Specifically, participants with a more accessible interdependent (vs. independent) self-construal reported higher stay-at-home adherence intentions as a consequence of greater IOS and self-control. Theoretical and practical implications are discussed.
