Food cue-induced craving in individuals with bulimia nervosa and binge-eating disorder [0.87 mb]
Abstract (English)

<span>Individuals with bulimia nervosa (BN) or binge-eating disorder (BED) experience more frequent and intense food cravings than individuals without binge eating. However, it is currently unclear whether they also show larger food cue-induced increases in craving (i.e., food cue reactivity) than those without binge eating, as suggested by conditioning theories of binge eating. A</span><span class="searchterm">group</span><span>of individuals with BN or BED (binge-eating</span><span class="searchterm">group</span><span>, n = 27) and a</span><span class="searchterm">group</span><span>of individuals with low trait food craving scores and without binge eating (control</span><span class="searchterm">group</span><span>, n = 19) reported their current food craving before and after a food cue exposure. Although food craving intensity significantly increased in both</span><span class="searchterm">groups</span><span>, this increase was significantly stronger in the binge-eating</span><span class="searchterm">group</span><span>than in the control</span><span class="searchterm">group</span><span>. This result is in line with conditioning models of binge eating that propose that food cues are conditioned stimuli that elicit a conditioned response (e.g., food craving) and that this association is stronger in individuals with binge eating. As food craving increased in individuals with low trait food craving scores as wellalthough to a lesser extentprevious null results might be explained by methodological considerations such as not screening control participants</span><span class="searchterm">for</span><span>trait food craving.</span>
