Within-person mixed-effects analysis of 458 university students (3,610 person-waves) tracked with Oura rings across 33 weeks, with bimonthly concern text processed through three NLP pipelines. The study reports that "Weeks dominated by academic concern framing were associated with lower physical activity" and emotional exhaustion language with poorer sleep and lower HRV. No effect sizes are printed for these associations.

"Weeks dominated by academic concern framing were associated with lower physical activity; weeks characterized by emotional exhaustion language were associated with poorer sleep quality and lower heart rate variability."

Discussion¶

Related Claims¶

• Dictionary-based SEANCE features yielded 21 nominally significant within-person associations with wearable outcomes, but none survived Bonferroni or FDR correction — a narrower finding that bears on this claim
• Wearable outcomes declined significantly across the academic year, including a 5.2% reduction in RMSSD and roughly 680 fewer steps per day by Week 33 — a narrower finding that bears on this claim
• Zero-shot classification of concern topics showed no consistent evidence of association with wearable outcomes, while affective dimensions showed more associations that did not survive correction — reports the opposite
• Forceful, assertive concern language was associated with fewer steps per day and lower moderate-intensity activity, while work-oriented language was positively associated with steps — a narrower finding that bears on this claim
