The authors write: "the experimental conditions did not show any improvements in
negative or positive mood relative to participants in the control condition (comments to table 3). The authors did not compute Affect Balance.
The data imply that Affect Balance has increased in the experimental group, PA going up and NA going down. Affect balance did not change in the control group. Statistical significance of this difference between experimental and control group has not been assessed.
