a Single items measured using a 1 (low) – 10 (high) ordered category scale; Importance reflects behavioural beliefs in which the motivation to change is influenced by the belief of how valuable a desired outcome [13]. Know-how, or having knowledge of how to change, reflects control beliefs, where individuals feel they have the requisite knowledge or skills to achieve an outcome. Confidence i.e., self-efficacy, is another facet of control beliefs, in which people perceived themselves as having agency to perform the given behaviour.
