Summary
AI-generated from the abstractA 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.

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.
