The impact of stress on sleep quality: a mediation analysis based on longitudinal data.

Objective: This study evaluates the potential mechanisms through which stress affects sleep quality and examines the mediating roles of rumination, social anxiety, emotion-focused coping strategies, and smartphone dependence in the relationship between stress and sleep quality.
