<p>This multi-wave longitudinal study investigated the role of ruminative response style in predicting dimensions of anxiety among individuals with negative inferential styles. Baseline and 6-month follow-up data were obtained from 446 adolescents with negative inferential styles. In the initial assessment, they completed measures evaluating ruminative response style, anxious symptoms, and negative events. Subsequently, over a 6-month period, they continued to report anxious symptoms and negative events. The results showed that the ruminative response style moderated the relationship between negative events and overall anxious symptoms. Notably, higher scores in ruminative response style were correlated with significant increases in all four subdimensions of anxiety (social anxiety, separation anxiety, physical anxiety, and harm avoidance). However, the Rumination and Stress interaction was significant only for the social anxiety and separation anxiety dimensions. Our findings suggest that increased rumination is significantly associated with heightened anxiety levels (specifically social and separation anxiety) under conditions of high stress. These results emphasize the critical moderating role of ruminative response styles in the relationship between stress and anxiety, highlighting its implications for intervention strategies targeting stress-related anxiety disorders.</p>
