Summary
The study explores the effects f training supervisors on self efficacy, attitudes towards workers, and productivity. Adopting an RCT design, the study provides mean comparisons (no t-tests) on the effects of training, combined with potential moderators such as cognitive load, fixed mindset, power at the workplace and zero-sum beliefs. The authors conclude that training had positive effects on all brand outcome categories: self-efficacy, attitudes toward workers, and productivity. These effects weer often moderated by mindset or perceived power. training was more effective when supervisors rejected a fixed mindset or zero-sum beliefs, felt less powerful (or less powerful than their managers), perceived manager support for Supervisory Skills Training, or felt more powerful than their workers.
