The effects of physical activity on mood states: a mediating model test
of boredom
First, the mediating effect of
boredom between physical activity and mood disturbance was tested using
Model 4 in PROCESS 3.3 (Model 4 is a simple mediating model). As shown
in table 5, physical activity had
a significant negative predictive effect on mood disturbance
(β =-0.17, t =-3.91, p <0.01),
and after the mediating variable
was added, the negative effect remained significant (β =-0.10,t =-2.94, p <0.01).
Physical activity had a
significant negative predictive effect on boredom (β =-0.11,t =-2.55, p <0.05), and
boredom had a significant positive
predictive effect on mood disturbance (β =0.61, t =17.62,p <0.01). In addition, the 95% bootstrap confidence
intervals for the direct effect of physical activity on mood disturbance
and the mediating effect of boredom did not contain 0.
As shown in table 6, physical
activity can not only directly predict mood disturbance but can also
predict emotional turmoil through boredom; its direct effect (-0.10) and
mediating effect (-0.07) accounted for 59.51% and 40.49% of the total
effect (-0.17), respectively.
