Abstract:
<jats:p> The COVID-19 pandemic presents acute, ongoing relationship challenges. The current research tested how (1) preexisting vulnerabilities assessed prior to the pandemic (attachment insecurity) and (2) stress as couples endured a mandated quarantine predicted residual changes in relationship functioning. Controlling for prequarantine problems, relationship quality, and family environment, greater partners’ attachment anxiety predicted greater relationship problems, lower relationship quality, and a less stable and cohesive family environment when people were experiencing more stress. Greater partners’ attachment avoidance predicted lower problem-solving efficacy and family cohesion. The effects of partners’ preexisting vulnerabilities and pandemic-related stress demonstrate the utility of key models in relationship science in identifying who is at most risk of relationship problems in the unprecedented context of a mandated quarantine. The results emphasize that the effects of the COVID-19 pandemic on relationship functioning will be shaped by the characteristics of partners with whom people are confined with during the pandemic. </jats:p>
