q2 · i? · associational · r2

Within-person mixed-effects semester decline model on Oura ring data (N=3,494 observations from 455 participants). The model shows RMSSD "declined from a model-predicted 66.9 ms at Week 1 to 63.4 ms at Week 33" with β=−1.03, p<.001. Only test statistics are printed, so no effect size is coded.

"RMSSD declined from a model-predicted 66.9 ms at Week 1 to 63.4 ms at Week 33 (𝛽=− 1.03, 𝑆𝐸= 0.17,𝑝<. 001), representing a 5.2% reduction in cardiac autonomic function across the academic year."

q2 · i? · associational · r2

Same semester decline model applied to physical activity outcomes (N=3,475 from 454 participants). Step count "declined from a predicted 11,455 steps/day at Week 1 to 10,777 steps/day at Week 33" with β=−200.1, p<.001. Sleep efficiency and onset latency also changed significantly; six of nine outcomes declined.

"Step count declined from a predicted 11,455 steps/day at Week 1 to 10,777 steps/day at Week 33 (𝛽=− 200.1,𝑆𝐸= 36.4,𝑝<. 001)"

Discussion¶

Related Claims¶

• 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 — related
• Brief naturalistic concern text associates with within-person variation in wearable-derived sleep and physical activity outcomes across a full academic year, even at a median response length of three words — a broader claim this one bears on
• Confirmatory physiological tests found no significant tool×task interactions for pupil Δ or ln RMSSD, with substantial data loss limiting interpretation — related
• Dictionary-based SEANCE features yielded 21 nominally significant within-person associations with wearable outcomes, but none survived Bonferroni or FDR correction — related
