The impact of the COVID-19 pandemic on pain and psychological functioning in young adults with chronic pain.

Data are equivocal on the consequences of COVID-19 pandemic on pain and well-being for individuals with chronic pain. Furthermore, little is known regarding its impact on the health of young adults with chronic pain. We conducted a longitudinal study to compare pain, psychological functioning, and substance use before and during the pandemic of 196 young adults with chronic pain. Participants aged 18 to 24 years (M = 21.1 years; 79.6% females) reported on pain, anxiety, depression, and substance use before (October 2018-August 2019) and during the pandemic (October 2020-November 2020), in addition to the assessment of COVID-19 exposure and its impact. Before the pandemic, young adults experienced mild-to-moderate pain intensity (M = 3.75, SD = 2.33) and pain interference (M = 3.44, SD = 2.69). Findings were that pain intensity, pain interference, and depression symptoms remained stable during the pandemic. In contrast, anxiety symptoms increased significantly (M = 8.21, SD = 5.84 vs M = 8.89, SD = 5.95, P = 0.04). Tobacco, alcohol, and cannabis use were unchanged. Mixed linear models revealed that COVID-19 exposure and impact were not associated with changes in pain intensity or interference, with female sex associated with increased pain intensity (β = 0.86, P = 0.02) and pain interference (β = 0.87, P = 0.02). Our findings indicated relative stability of pain symptoms experienced by young adults with chronic pain. However, the increases in anxiety highlight the need to facilitate treatment access for mental health services to mitigate downstream impact.
