Using the Theory of Planned Behavior as a framework, Attitude to Physical Activity, Expectations of Others, Perceived Control, and Intention to Engage in Physical Activity Scales were developed for use among both adolescent males and females. Experts in exercise physiology and the sports sciences generated items for the instruments and established content validity. The scale items are phrased in a Likert scale format. Both unipolar and bipolar scales were developed with seven response choices offered. Following pilot testing and subsequent revisions, 32 items were retained in the Attitude to Physical Activity Scale, 10 items were retained in the Expectations of Others Scale, three items were retained in the Perceived Control Scale, and 24 items were retained in the Intention to Engage in Physical Activity Scale. Correlation coefficients for the total instruments were significantly positive for stability and internal consistency, ranging from α = .81 to α = .96. These instruments are ready for application in the field and may be used to develop intervention techniques for promoting positive attitudes toward physical activity, good perception of control over the ability to participate in physical activity, and good intentions to participate in physical activity.
