Some like it vigorous: measuring individual differences in the preference for and tolerance of exercise intensity

Individuals differ in the intensity of exercise they prefer and the intensity they can tolerate. The purpose of this project was to develop a measure of individual differences in the preference for and tolerance of exercise intensity. The steps involved in (a) item generation and face validation, (b) exploratory factor analysis and item selection, (c) structural validation, (d) examination of the internal consistency and test-retest reliability, (e) concurrent validation, and (f) construct validation are described. The Preference for and Tolerance of the Intensity of Exercise Questionnaire (PRETIE-Q) is a 16-item, 2-factor measure that exhibits acceptable psychometric properties and can be used in research aimed at understanding individual differences in responses to exercise and thus the psychological processes involved in the public health problem of exercise dropout.
