I would like to use an effect size from the study 'Trait Reappraisal Amplifies Subjective Defeat, Sadness, and Negative Affect in Response to Failure Versus Success in Nonclinical and Psychosis Population' to run a power analysis in G*power. Specifically, I am looking at the interaction between reappraisal and feedback for sadness OR negative affect. However, I do not know which values I should be looking at, and how I can use them to calculate the f-squared effect size to be entered into G*power for my hierarchical regression. I was wondering if anyone knew how to overcome this issue?
