Trajectories of loneliness during COVID-19 pandemic and associations with mental health and substance use.

We examined patterns of longitudinal trajectories of loneliness during the COVID-19 pandemic using six time points (January 2020 [pre-pandemic] to March/April 2021) and whether trajectories were associated with psychological distress (depression/anxiety) and substance use (alcohol/cannabis) outcomes in Spring 2021. Participants were 644 young adults who completed online assessments. Outcomes were regressed on most-likely loneliness trajectory adjusting for pre-pandemic measures. Three loneliness trajectories varied from consistently lower to consistently higher. Pre-pandemic social support was associated with lower odds of a higher loneliness trajectory. Higher loneliness trajectories were associated with greater odds of past-month cannabis use compared to Low trajectories, but not significantly associated with depression, anxiety, or alcohol use in Spring 2021. Interventions addressing co-occurring loneliness and cannabis use are needed.

Multifaceted COVID-19-Related Stressors and Associations with Indices of Mental Health, Well-being, and Substance Use Among Young Adults.

Alongside direct health concerns pertaining to the SARS-CoV-2 virus, the stressors and life disruptions associated with the COVID-19 pandemic may provoke secondary concerns for health and well-being. The implications of COVID-19-related stressors may be particularly salient for young adults, who are at higher-risk for mental health concerns and substance use behaviors. We developed a multifaceted scale that assessed distinct domains of COVID-19-related stressors and examined associations between these stressors and indices of mental health, well-being, and substance use (alcohol and marijuana use). In April-June of 2020, 1181 young adults were recruited from two- and four-year colleges to participate in this study (M age = 20.40; 59.95% women). Exploratory factor analysis identified five domains of COVID-19-related stressors: job insecurity, social/relational, financial, illness-related, and school-related. The overall pattern of results indicated that COVID-19-related stressors were related to poorer mental health and well-being. Social/relational stressors emerged as a primary concern most strongly associated with indices of mental health and alcohol use, relative to other stressors. However, illness-related stressors and school-related stressors were associated with less alcohol use. Stressors associated with the COVID-19 pandemic may impact young adults' health and well-being but disentangling various stressor domains informs more tailored intervention and prevention strategies.

Increases in Loneliness Among Young Adults During the COVID-19 Pandemic and Association With Increases in Mental Health Problems.

PURPOSE: Young adults are at high risk for increases in loneliness and mental health problems during the COVID-19 pandemic. The present study examined increases in loneliness in a young adult sample, for whom increases were greater, and association with increases in depression and anxiety. METHOD: Data from 564 young adults (ages 22-29, 60.7% women) were collected in January 2020 (pre-pandemic) and April/May 2020 (during pandemic). RESULTS: Loneliness increased from January to April/May and changes in loneliness were greater for females, those with higher perceived social support in January, and those with greater concerns about the pandemic's social impacts. Depression (but not anxiety) increased during this time with changes in loneliness accounting for much of the increase in depression. CONCLUSIONS: Intervention strategies with young adults need to address loneliness and feelings of reduced social support during this time, especially for those who may have had greater disruption in their social lives.
