| A nationwide quarantine was placed during the beginning of the COVID-19 pandemic, which increased isolation. Using a behavioral economics framework, the current study explored the extent to which the quarantine constrained the array of available reinforcers, changed time allocation to reinforcers, and affected health behaviors related to eating. Fifty-one participants retrospectively reported time and value allocation towards twelve reinforcers (e.g., friends, family, and travel) at three time points: pre-, during, and post-quarantine. Results suggested the overall range of available reinforcers during quarantine was reduced, decreasing time for more restricted reinforcers (e.g., travel, friends), and increasing time for less restricted reinforcers (e.g., social media) during quarantine. Value for all twelve reinforcers remained constant except for school and exercise (increased post-quarantine) and social media (increased during quarantine). Moreover, food intake increased during quarantine, suggesting that constraint of reinforcers during quarantine lead to increased food intake which may be related to weight gain. |
