Abstract
The Questionnaire: Peak Performance and Peak Experience is based on both research and theoretical content found through a comparative analysis of literature germane to peak performance, peak experience, and flow. The Dale-Chall Readability Formula indicated that readability of the questionnaire is at the upper limits of the 9th and 10th grades. A Pearson product-moment correlation, based on 33 paired trials, was used to estimate over-all reliability (.70) and reliability of 42 individual test items. Scores were from 21 women and 12 men, aged 20 to 49 yr.
