Participants were 5 coaches with a mean age of 39.8 years (SD = 8, 6) and a mean experience of 9 years (SD = 5). Results show that after the training program coaches improved their supportive behaviors; and 4 of the 5 coaches decreased punitive behaviors; and increased technical instructions contingent to mistakes.
