*3.3. Did Rates of Depression, Anxiety, and Stress Increase Significantly during the Quarantine Period?*

Rates of mild, moderate, severe, and very severe symptoms on DASS-21 scales for the whole sample are given in the first panel of results in Table 3. When cases in mild, moderate, severe, and very severe categories were combined and compared to those in the normal category, there were increases in rates of symptoms on all three DASS-21 scales from pre-quarantine to the quarantine period. The rate of depression increased from 30 to 46.3% (*X*<sup>2</sup> (1, *n* = 847) = 67.92, *p* < 0.0001). The rate of anxiety increased from 30.7 to 32.5% (*X*<sup>2</sup> (1, *n* = 847) = 121.71, *p* < 0.0001). The rate of stress increased from 27.7 to 34% (*X*<sup>2</sup> (2, *n* = 847) = 4.99, *p* = 0.025).
