Interpersonal Stressors and Adolescent Mental Health During COVID-19: Investigating the Role of Loneliness

Abstract The COVID-19 pandemic created social disruptions, leading to high levels of mental health problems for adolescents. Interpersonal stressors, such as lack of familial support, peer victimization, and discrimination, may have further exacerbated teen mental health issues. Yet, the psychological impact of interpersonal stressors and their interactive effects with high levels of loneliness remains unknown. In this pre-registered study , conducted in November and December 2020 (approximately eight months into the COVID-19 pandemic), we used a diverse sample of adolescents from across 43 U.S. states with elevated depressive symptoms (n = 2,452, ages 13–16) to examine how familial support, peer victimization, and discrimination are concurrently associated with mental health outcomes. Results indicated that perceived discrimination was the strongest standardized correlate across continuous internalizing outcomes (depressive symptoms, anxiety symptoms, and hopelessness), whereas lack of familial support was the primary correlate of suicidal ideation; if youth reported a lack of familial support, they were over three times as likely to report suicidal ideation. Loneliness significantly moderated the cross-sectional links between lack of familial support and depressive symptoms, as well as perceived discrimination and hopelessness. Simple slope probing demonstrated a distress ceiling effect: interpersonal stressors were most strongly associated with elevated distress among youth reporting low baseline loneliness, whereas youth experiencing high loneliness exhibited consistently elevated distress regardless of stressor exposure. These findings underscore interpersonal stressors and loneliness as high-priority targets for youth prevention and intervention programs, particularly during periods of widespread social disruption.
