Erratum: Changes in Physical Activity, Sleep, Mental Health, and Social Media Use During COVID-19 Lockdown Among Adolescent Girls: A Mixed-Methods Study (J Phys Act Health (2021) 18:6 (677–685) DOI: 10.1123/jpah.2020-0649)

The authors identified an error with the automatic recoding of data within three questionnaires (Body Weight and Appearance Satisfaction; Behavioural Regulation in Exercise Questionnaire-3 [BREQ-3]; Emotion Regulation Questionnaire for Children and Adolescents [ERQ-CA]) that were administered to participants using Qualtrics. Following re-analysis, the article has been updated to reflect the correct data in the following sections: 1) Results: Well-Being; 2) Table 3. A previous version of the article stated that the authors noted a decrease in motivation for exercise and an increase in self-efficacy for happiness with appearance during lockdown. Following re-analysis, these conclusions have been removed from the article. The article was corrected November 15, 2022. The authors apologize for the error.
