In a random sample from the general population (N = 2781, 46% males), a longitudinal survey was conducted. The association between dispositional self-control and changes in eating behaviours and diet quality was analysed between the first wave (2010) and the last wave (2014). Results show that the higher the dispositional self-control, the lower the increase in overeating behaviours (emotional eating, external eating, ambivalence towards palatable food and overeating), and BMI and the larger the improvement in healthy diet over time. Self-control was not associated with changes in dietary restraint. This is one of the first studies suggesting that dispositional self-control is associated with changes in eating behaviours and healthy food intake over time.
