Notes: df_num/df_den= degrees of freedom of numerator/denominator.

^aPositive values indicate effects in favor for the climbing intervention.

^bFor positive affect, a mixed 2×2 analysis of covariance with baseline values of positive affect as the covariate was conducted.

^*Statistical significance after Bonferroni correction (p=0.0125).

Abbreviation: CI, confidence interval.
