Associations between Relationship Quality and Mental Health during COVID-19 in the United Kingdom.

This study investigated the association of relationship quality with several well-being measures during the COVID-19 lockdown in the United Kingdom. An online survey was conducted on a study sample (n = 682) measuring relationship quality with the Quality of Marriage Index, and well-being measures including quality of life (WHO-QoL BREF), well-being (WHO-5), perceived stress (PSS-10), depressive (PHQ-9), and anxiety (GAD-7) symptoms. Good relationship quality goes along with higher scores in well-being (WHO-5), quality of life (WHO-QoL BREF), psychological domain, physical health, social relationships, environment, and reduced scores in stress (PSS-10), depressive (PHQ-9) and anxiety (GAD-7) symptoms compared with poor relationship quality (p < 0.001). Moreover, 21% of participants living in relationships with poor quality stated that they drink significantly more alcohol since the initial COVID-19 restrictions, compared to 10% of participants with good quality (p = 0.002). Living in a good relationship seems to be an advantage, whereas those with poor relationship quality are particularly more burdened and drink significantly more alcohol during the COVID-19 lockdown.
