Overview

This longitudinal study examines anxiety trajectories in junior high students, revealing the influence of family functioning and gender on non-suicidal self-injury risk.

Key Points

  • The study aims to explore the developmental trajectories of anxiety in junior high students and their predictors, focusing on gender and family functioning effects.
  • Conducted a three-wave longitudinal study with 1479 junior high students over two years.
  • Employed Latent Growth Curve Modeling to analyze anxiety development trajectories.
  • Utilized Latent Class Growth Modeling to identify distinct subgroups of anxiety trajectories.
  • Applied multivariate logistic regression to assess the predictive validity of gender and family functioning on trajectory class membership.
  • The overall anxiety trajectory showed a linear increase over time.
  • Female students exhibited higher initial anxiety levels and more rapid increases than male students.
  • Family functioning was found to have a significant negative predictive effect on anxiety levels.
  • Three distinct classes of anxiety trajectories were identified: High/Increasing, Moderate/Increasing, and Low/Decreasing.
  • Students in High/Increasing and Moderate/Increasing classes had a greater likelihood of engaging in non-suicidal self-injury (NSSI).
