1 The sum of absolute differences between self-assessment and assessors’ scores for all of the 22 items. The maximum aggregated score a participant can get is 88 (22 items * 4 points)
2 Sphericity assumption was met and assumed
3 observed power was computed using an alpha value of 0.10
* significant difference P < 0.10
