ACS 90 subscales AOF and AOD: higher values on these scales are supposed to positively correlate with stages 3 and 4 (AOD) and stage 2 (AOF).
Problem awareness: positive correlation of high problem awareness scores with stages 2, 3, 4. Usage of information and of services/counselling: positive correlation with stages 3 and 4; severity of child overweight: complex relation to the stages of change (parents of highly obese children may be more motivated for change), however a positive correlation of weight and stages 1 (and 2) is assumed.
Media consumption: a lot of media consumption (hour/day) is supposed to positively correlate with stages 1 (and 2) and vice versa for stages 3 and 4.
Movement behaviour: a lot of movement (hour/day) is supposed to positively correlate with stages 3 (and 4) and vice versa for stages 1 and 2.
