Chapter 3 50 the model distinguishes between two types, descriptive norms and injunctive norms, and two sources, parents and peers. In addition, the model tests the hypothesis that all the social norm constructs predict changes in consumption behavior. Integrating the self-determination theory perspective, the model tests whether a direct relationship exists between intrinsic motivation and changes in young adolescents’ consumption. Figure 3.1 SEM model predicting fruit and vegetable consumption Note. Boxes represent observed variables and ellipses latent variables. The same conceptual model was tested for water consumption, except that behavior was an observed variable. The paths in the conceptual model represent regression paths that were estimated using structural equation modelling. Sex, school cohort, z -BMI and hunger/ thirst were included in both SEM models as covariates.
