Motives (1) Self motivated –High on intrinsic motivation – opposed to extrinsic forces Supported –High on intrinsic motivation but also recognise extrinsic forces

Motives (2) Lukewarm –Low on intrinsic motivation – opposed to extrinsic forces Pressured –Lowest on intrinsic motivations but recognise external pressures to consume fruit and vegetables.
