Reliability and Readability of Questionnaire: Peak Performance and Peak Experience
Psychological Reports April 1, 1986 Gayle Privette, David Sherry
A questionnaire measuring peak performance, peak experience, and flow was developed from a comparative analysis of relevant literature. Its readability, assessed by the Dale-Chall formula, is at the upper 9th to 10th grade level. Reliability was estimated using data from 33 paired trials (21 women, 12 men, ages 20–49), yielding an overall reliability coefficient of .70 and individual item reliabilities.
