An integrated perspective on the longitudinal relationship and developmental trajectories of Self-Identity and adolescent psychological distress: the protective role of dispositional mindfulness
摘要
According to Erikson’s theory of psychosocial development, adolescence represents a critical stage marked by the crucial developmental task of establishing self-identity, closely linked to emotional health. The interrelationship and co-evolutionary trajectory between adolescent self-identity and psychological distress, however, remain underexplored. While the positive effects of dispositional mindfulness on adolescents’ emotional health are acknowledged, its specific influence within the broader context of adolescent development merits deeper investigation. Therefore, this study attempted to examine the longitudinal relationship and developmental trajectory between adolescent self-identity and psychological distress from an integrated perspective, adopting a homogeneous and heterogeneous approach. Furthermore, it sought to explore the protective role of dispositional mindfulness within these dynamics. A cohort of 1293 Chinese adolescents underwent sequential assessments at three-month intervals across three waves. Measurements encompassed self-identity and psychological distress at each time points, with dispositional mindfulness assessed at the initial time point. The results of parallel process latent growth model for self-identity and psychological distress showed that higher initial levels of self-identity were associated with lower initial level of psychological distress. Furthermore, a faster growth rate in self-identity corresponded to a slower growth rate in psychological distress. Subsequently, employing parallel process growth mixed analysis, this joint developmental model was partitioned into two distinct classes:"low self-identity, high psychological distress: Risk-NE declining" and "high self-identity, low psychological distress: Health- potential risks". In addition, dispositional mindfulness emerged as a predictor of both initial levels of self-identity and psychological distress. Adolescents with elevated dispositional mindfulness exhibited an increased likelihood of belonging to the "Health-potential risks" class. These findings underscore the reciprocal relationship between self-identity and psychological distress over time, thereby emphasizing the need for interventions to target both self-identity and psychological distress. Additionally, a consistently elevation of dispositional mindfulness appears essential in promoting adolescent emotional well-being.
