Note. Entries refer to means and standard deviations are in parentheses. Different superscripts mean there are significant differences in corresponding variables between users and non-users. Subscripts are based on ANCOVA analysis between posters and lurkers. Cells with different superscripts/subscripts differ at p < .05 at the minimum. All analyses adjusted for seven baseline characteristics from Table 1.
