^aChange in daily playtime is measured using a 1 to 5 scale. Table 1 provides further details (referenced as CH).

^bDescriptive statistics of change in daily playtime per depression severity levels: severe depression (n=50; mean 4.20; SD=0.88); moderately severe depression (n=140; M=3.82; SD 0.84); moderate depression (n=254; mean 3.78, SD 0.82); mild depression (n=787; mean 3.69, SD 0.82); minimal depression (n=663; mean 3.63, SD 0.84).

^cAll t tests were 2-tailed.
