- The table presents means for the VAS (visual analogue scale) ratings provided at the start (VAS pre-) and at the end (VAS post-) of each survey assessment for the sample overall, and by self-harm Status and Gender. Standard deviations are shown in parentheses
- “SH yes” denotes lifetime incidence of self-harm. “SH no” denotes no reported history of self-harm
- a A significant interaction between mean mood-change score for boys and girls at the level of SH yes F(1467) = 8.189, p = .004, η2 = .017 which survives Bonferroni correction at p = .025
- b A statistically significant difference between VAS pre- and VAS post-survey scores, t = 3.807, p < .0001
