Generational Shifts in Adolescent Mental Health: A Longitudinal Time-Lag Study.

Abstract

There is concern that adolescents today are experiencing a "mental health crisis" compared to previous generations. Research has lacked a longitudinal time-lag design to directly compare depressive symptoms and social anxiety of adolescents in two generations. The current study surveyed 1081 adolescents in the current generation (Mage = 14.60, SD = 0.31, 49% female) and 1211 adolescents in a previous generation (Mage = 14.40, SD = 0.51, 51% female) across the high school years (grades 9-12), 20 years apart. Mixed-effects analysis revealed that the Current-Sample reported higher and increasing mental health problems over time compared to the Past-Sample. Although most adolescents reported consistently low mental health problems, the Current-Sample had a higher proportion of adolescents who were consistently at risk across the high school years compared to the Past-Sample. These findings highlight while most adolescents in both generations do not report elevated mental health problems, there may be a small, yet growing, group of adolescents today at risk for experiencing a "mental health crisis".
