The authors regret an error in the published manuscript.
In the final sentence of the fourth paragraph on page 5, the value of Cohen’s d was incorrectly reported: ‘State anhedonia was also negatively associated with momentary PA with peers (b = −10.08, p < .001, Cohen’s d = −1.70); on occasions in which adolescents felt more anhedonic, they reported lower levels of PA when in the presence of peers.’
The correct value for Cohen’s d is −0.51, as accurately presented in Table 2.
This has been corrected in the HTML and PDF versions of the article.
