Notes. For F tests:
*
p < .05.
**
p < .01.
***
p < .001.
****
p < .0001. An FDR correction was applied for tests conducted in primary analyses; the adjusted p-value for significance is p < .016. Effects meeting this corrected threshold are bolded. T1 = Time 1 (pre-pandemic survey, late January/early February 2020). T3 = Time 3 (June 2020 survey). Sx = symptoms. HAnxiety = health anxiety. Lonely = loneliness.
