Changing intentions to use smokeless tobacco: an application of the IMB model.

Objective: To determine if the Information-Motivation-Behavioral Skills model was effective for development of a smokeless tobacco educational unit (STEU) and analysis of STEU effects.

Methods: Structural equation modeling was used to test component relations proposed by the IMB model and STEU effects on parallel growth of IMB components.

Results: Results confirmed IMB model component relationships and indicated that STEU effects were primarily on information with indirect effects on expectancies and self-efficacy change through information.

A Validation and Reliability Study of the Physical Activity and Healthy Food Efficacy Scale for Children (PAHFE).
