An Empirical Examination of Posttraining On‐the‐job Supplements for Enhancing the Effectiveness of Interpersonal Skills Training

This study examined the impact of 2 posttraining on‐the‐job supplements to a training program focused on interpersonal skill development for newly hired managers—self‐coaching and upward feedback. Utilizing a sample of 87 trainees from 75 units of a national restaurant chain, the impact of these supplements was assessed by examining posttraining performance across 4 training conditions in a quasi‐experimental framework: (1) classroom training only, (2) classroom training with self‐coaching, (3) classroom training with upward feedback, and (4) classroom training with self‐coaching and upward feedback. The results demonstrated that both supplements are useful extensions to formal classroom training for enhancing trainees' interpersonal performance. These findings are discussed along with directions for future training effectiveness research.
