Development and practical implications of the Exercise Resourcefulness Inventory.
OBJECTIVE
To determine the validity and reliability of the Exercise Resourcefulness Inventory (ERI) designed to assess the self-regulatory strategies used to promote regular exercise.


METHODS
In Study 1, the inventory's relationship with other established scales in the exercise behavior change field was examined. In Study 2, the test-retest reliability and predictive validity of the ERI was established by having participants from Study 1 complete the inventory a second time.


RESULTS
Internal consistency, and convergent, discriminant, and concurrent validity were supported in both studies. The test-retest correlation of the ERI was .80. As well, participants scoring higher on the ERI in Study 1 were more likely to be at a higher stage of change in Study 2, and greater increases in exercise resourcefulness over time were predictive of advancement to higher stages of change.


CONCLUSIONS
ERI is a reliable and valid measure to assess the self-regulatory strategies used to promote regular exercise.


CONCLUSIONS
Facilitators may want to tailor exercise programs for individuals scoring lower in resourcefulness to prevent them from relapsing.
