Bold values are statistically significant.
*Highly motivated/satisfied = ≥6/7 for ≥2/3 of lifestyle behaviours/satisfaction measures.
†Highly motivated = ≥6/7 for 2/2 lifestyle behaviours.
‡Optimal = self-reported lifestyle behaviours achieving guideline indicated thresholds for ≥2/3 of exercise, vegetable intake and fruit intake. All measures adjusted for age, gender, educational level and total time in clinic.
