Reviewer 2 Report

Thank the authors for addressing my concerns and for adding scale version as a moderator in particular. A main conclusion of this paper is "Compared to those reporting ‘average - high’ starting wellbeing, participants reporting ‘low’ starting wellbeing exhibited greater improvements (BCa 95% CI [-31.8, -26.5])" and I feel that at least this data should be presented in a Figure rather than less than one sixth of a table (Table 3).
