Moderation by access to different foods, sex and the personality trait reward sensitivity is tested.<\/p>\n<p style=\"text-align:justify\"><strong>METHODS<\/strong><br \/>\nIn a computerized Food Reinforcement Task, adolescents could earn portions of a healthy and an unhealthy snack following an identical progressive reinforcement schedule for both food types. Reinforcing value of food was indexed by the number of button presses for each food type. Participants were allocated randomly to two-order condition: fruit-snack versus snack-fruit. Reward sensitivity was assessed with the Dutch age-downward version of Carver and White&#039;s BIS\/BAS scale.<\/p>\n<p style=\"text-align:justify\"><strong>RESULTS<\/strong><br \/>\nResults showed that the reinforcing value of an unhealthy snack is higher than that of fruit, with participants making more button presses for unhealthy snacks, M&nbsp;=&nbsp;1280.40, SD&nbsp;=&nbsp;1203.53, than for fruit, M&nbsp;=&nbsp;488.04, SD&nbsp;=&nbsp;401.45, F(1,48)&nbsp;=&nbsp;25.37, p&nbsp;&lt;&nbsp;0.001. This effect is stronger in boys (&beta;&nbsp;=&nbsp;-1367.67) than in girls (&beta;&nbsp;=&nbsp;-548.61). The effect is only present in the snack-fruit condition, not in the fruit-snack condition, indicating that access to food moderates the effect of food type. There is no evidence for moderation by reward sensitivity.<\/p>\n<p style=\"text-align:justify\"><strong>CONCLUSIONS<\/strong><br \/>\nResults point to the importance of simultaneously increasing barriers to obtain unhealthy food and promoting access to healthy food in order to facilitate healthy food choices.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-17952","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Developmental, Personality and Social Psychology, Ghent University, H.
