This study aimed 1) explore interrelationships among within-day worrying, feeling anxious, and symptoms, 2) investigate association between these overall level FSS. included 767 participants (83% females, mean age 39 years), who were recruited through an online crowdsourcing Dutch general population. Somatic, reported thrice daily (6-h intervals) for 30 days using electronic diaries. FSS assessed at baseline (PHQ-15). Temporal relationships modeled a multilevel vector autoregressive model. We observed large heterogeneity within-person anxious Averaged over participants, higher-than-usual associated with increases levels worrying six hours later (B = 0.017, 95% CI [0.006, 0.027]). At between-person level, predicted persistence 0.230 [0.105, 0.350]) carry-over six-hours 0.159, [0.031, 0.283]). In contrast what we expected, higher multiple weeks anxiety-related One psychological during day was observed, suggesting that, time span 6-h, relate only minority people from
