我们研究了COVID-19封锁对英国消费场合频率和软饮料消费量的影响。饮料消费与特定的、通常是社交的消费情境（如外出）密切相关。我们推断，封锁会影响消费行为，因为它消除了典型的软饮料消费情况。具体来说，我们假设在封城期间，软饮料的消费场合和数量与封城前后相比会减少，特别是在典型的软饮料消费情况下。在两项调查中（2020年12月和2021年5月），对同一参与者（N= 211，N= 160；每周至少喝一次软饮料），我们评估了2020年11月/ 12月封锁之前、期间和之后的软饮料和水消费场合的频率，包括典型的软饮料和水饮用情况。这张图详细描述了参与者喝软饮料和水的情况，以及封锁对这种情况的影响。我们还评估了每个时期每天饮用软饮料和水的量，以及饮用软饮料和水的感知习惯。正如预测的那样，与封锁前后相比，参与者报告说，在封锁期间喝软饮料的场合更少，尤其是在典型的软饮料消费情况下。然而，出乎意料的是，与封锁前后相比，封锁期间的每日软饮料消费量有所增加，尤其是在软饮料消费习惯较强的参与者中。探索性分析表明，在封锁期间，参与者在家中增加了软饮料的消费量。另一方面，水的消耗并没有受到封锁的系统性影响。这些发现表明，即使一些典型的消费情况消失了，如果这种行为是有益的，消费可能很难被打断。
We examined the impact of a COVID-19 lockdown in England on the frequency of consumption occasions and amount of soft drinks consumed. Beverage consumption is strongly associated with specific, often social, consumption situations (e.g., going out). We reasoned that lockdown would affect consumption behaviour because it removed typical soft drink consumption situations. Specifically, we hypothesised that soft drink consumption occasions and amount would be reduced during lockdown compared to before and after lockdown, especially in typical soft drink consumption situations. In two surveys (Dec. 2020 and May 2021) among the same participants (N= 211,N= 160; consuming soft drinks at least once/week), we assessed the frequency of soft drink and water consumption occasions before, during, and after the November/december 2020lockdown, across typical soft drink and water drinking situations. This presents a detailed picture of the situations in which participants drink soft drinks and water, and how this was affected by a lockdown. We also assessed the daily amount of soft drinks and water consumed in each period, and perceived habitualness of drinking soft drinks and water. As predicted, participants reported fewer occasions of drinking soft drinks during lockdown compared to before and after, especially in typical soft drink consumption situations. Unexpectedly, however, the daily amount of soft drinks consumed increased during lockdown, compared to before and after, especially among participants with stronger perceived habitualness of soft drink consumption. Exploratory analyses suggest that during lockdown, participants increased their soft drink consump--tion at home. Water consumption, on the other hand, was not systematically affected by the lockdown. These findings suggest that even if some typical consumption situations disappear, consumption may be hard to disrupt if the behaviour is rewarding.
