Objective: To examine the moderating influence of ethnicity on the theory of planned behavior (TPB) in the exercise domain and to generate common and ethnic-specific underlying accessible beliefs.
Methods: 90 Caucasian and 94 African American undergraduate students completed a TPB questionnaire.
Results: Multilevel modeling analyses indicated that ethnicity and gender interacted by moderating the relationships between exercise intention and effective (beta = -0.44) and instrumental (betaeta = 0.39) attitudes. Furthermore, common and ethnic-specific underlying accessible beliefs were identified.
Conclusion: When exercise interventions are developed, ethnicity and gender may need to be considered when dealing with affective and instrumental attitudes.
