Early family adversity trajectories and mental health in emerging adulthood: Differential impacts of contextual insecurity and relational adversity

This study examines continuity and changes across contextual insecurities (intimate partner violence, material hardship) and relational adversities (parenting stress, maternal depression) from infancy to preschool years and explores their long-term influence on young adults' mental health at age 22. The sample was drawn from the Future of Families and Child Wellbeing Study (<i>N</i> = 4,677; 52.3% male, 21.2% White, 47.77% Black, 27.15% Latinx, 3.88% Other). The multidimensional growth mixture model identified five trajectory classes: <i>Low Adversity</i>, <i>High-Stable Parenting Stress</i>, <i>High-Increasing Material Hardship</i>, <i>High-Decreasing IPV</i>, and <i>Multidimensional Persistent Adversity</i>. Young adults in the <i>Multidimensional Persistent Adversity</i> and <i>High-Decreasing IPV</i> classes reported higher depression and anxiety than those in the <i>Low Adversity</i> or <i>High-Stable Parenting Stress</i> classes. Findings highlight the need for tailored early intervention to alleviate chronic and multidimensional adversities within family systems. It also emphasizes implementing trauma-informed intervention programs to support emerging adults' mental health and thriving.
