An Integrated Model 3 59 Water Consumption The model examining water consumption showed a good fit to the observed data, χ 2 (155) = 385.989, CFI = .94, and RMSEA = .04. Factor loadings of the latent constructs (Attitude, Self-Efficacy, and Intrinsic Motivation) ranged from λ = .73 to λ = .89, p < .001. Model estimates indicated a similar pattern to the model predicting changes in fruit and vegetable consumption (see Table 3.2). Self- Efficacy at T1 predicted changes in participants’ Intentions to drink water from T1 to T2. Participants’ Intrinsic Motivation to drink water at T1 predicted changes in their water consumption from T2 to T3, as well as from T3 to T4. In addition, the Descriptive Norms of parents at T1 also predicted changes in participants’ water consumption from T3 to T4.
