Prior research has shown that routines and beneficial habits largely explain high self-control people's success at goal pursuit. However, COVID-19 self-quarantine measures and country-level lockdowns have largely challenged people's ability to stick to their daily routines and habits. How successful at goal pursuit are people with high self-control when the world around them is not as it used to be? We examined if self-control passes the ‘quarantine test’. In an online study (N = 271), we measured trait self-control, goal progress, continued engagement in pre-pandemic goal-directed behaviors, development of new goal-directed behaviors and turning these new behaviors into habits. Results showed that during lockdown, people with higher (vs. lower) trait self-control were not only more likely to continue engaging in pre-pandemic goal-directed behaviors, but also found it easier to develop new goal-directed behaviors and were more likely to turn these behaviors into habits. High self-control people's ability to continue performing pre-pandemic goal-directed behaviors and to turn new behaviors into habits explained their success at goal attainment despite the major disruptions caused by the pandemic.
