Abstract
• Worry was associated with difficulty concentrating across three pandemic timepoints. • Anxiety predicted worry three months later, controlling for concurrent worry. • Worry partially mediated the path from T1 anxiety to T3 difficulty concentrating. • Mediation was not robust to controlling for outcomes at previous timepoints. Difficulty concentrating is an understudied cognitive phenomenon, despite its status as a diagnostic criterion for generalized anxiety disorder and contributor to clinically significant distress and impairment. Worry may constitute a cognitive mechanism by which anxiety leads to difficulty concentrating. The present study examined concurrent and prospective associations between self-reported anxiety, worry, and subjective difficulty concentrating across three timepoints (T1 April/May, T2 July/August, T3 October/November 2020) in 198 adults ( M age = 37.94, SD = 13.42; 81% women, 2% gender minority) drawn from a larger study of trajectories of psychopathology during the COVID-19 pandemic. In multilevel models, anxiety was associated with worry both between ( β = 0.65, SE = 0.13) and within participants ( β = 0.12, SE = 0.11). Difficulty concentrating was also associated with worry between ( β = 0.38, SE = 0.03) and within participants ( β = 0.09, SE = 0.02). In a structural equation model , worry partially mediated the longitudinal association between anxiety and difficulty concentrating, though this effect was nonsignificant after controlling for difficulty concentrating at T2 and worry, depression, sleep disturbance, and difficulty concentrating at T1. The unadjusted mediation and these other findings are in line with theoretical accounts of worry as a cognitive mechanism linking anxiety to subjective attentional problems .

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
