Fig 4. Association of the differences in PROMIS scores mid-pandemic versus pre-pandemic with differences in STAI and BDI scores.

Increases in sleep disturbance scores during the pandemic are positively associated with increases in (A) anxiety scores (R² = 0.258, β = 0.508, p = 0.045) and (B) BDI scores (R² = 0.305, β = 0.552, p = 0.022).
