Longitudinal Changes in Psychosocial Adjustment Before and During the COVID-19 Pandemic for Adolescents with Differential Patterns of Solitude and Sociability

Previous research has lacked a comprehensive, longitudinal analysis of characteristics of solitude and sociability, and how they are associated with changes in psychosocial adjustment before and during the pandemic. The current study surveyed 1071 adolescents (Mage = 10.6, SD = 1.69, 49.86% female, age range = 8–14 years at Year 1) over six years (three years before pandemic, three years during pandemic). Piecewise linear mixed-effects analysis showed that adolescents with higher solitude and lower sociability reported improvements in adjustment during the pandemic, whereas adolescents with lower solitude and higher sociability reported declines in adjustment. The findings highlight the importance of considering multiple characteristics of solitude and sociability, as well as contextual factors (e.g., pandemic), to better understand the implications of solitude on adolescent adjustment.
