Abstract
PURPOSE
Explore whether adults'physical activity behavior or their use of physical activity behavior-change strategies, as derived from the Transtheoretical Model, differed by handedness.
METHODS
A cross-sectional survey of 151 adults' hand preference (i.e., handedness: right, left, ambidextrous) and their use of the behavioral and cognitive processes of change, decisional balance scores (i.e., pros minus cons), self-efficacy, and their stage of change for physical activity involvement.
RESULTS
Left-handers showed significantly less use of the behavioral and cognitive processes of change compared to right-handers (M = 46.9 vs. M = 40.5 and M = 46.9 vs. M = 40.5, respectively). Left-handers were also significantly more likely to be in the earlier (i.e., inactive or irregularly active) stages of change relative to right-handers (84.6% vs. 48.1%, respectively).
DISCUSSION
Handedness may be a previously unrecognized, heritable correlate of physical activity behavior and the use of physical activity behavior-change strategies.
