As specified in our preregistered protocol, we explored moderation effects with significance set at P < .10. As a result, 90% CIs are provided. When significant moderator effects were found, estimates of effects at specific levels of the moderator are displayed. Low socioeconomic status = mean −1 SD. High socioeconomic status mean +1 SD. Low fundamental movement skills = first quartile. High fundamental movement skills = third quartile.
