Background <p>Obesity is a major public health problem related to a host of negative consequences (e.g., medical, financial, etc.). While traditional interventions (e.g., dieting and physical activity) prove efficacious for some, individuals with obesity frequently experience mental health comorbidities that are often not addressed within the context of such interventions. The current study examined the association between anxiety sensitivity (AS; i.e., fear of anxiety-related sensations) sub-facets of physical, cognitive, and social concerns on various eating expectancies (i.e., expectancies of eating to help manage negative affect, expectancies of eating to lead to feeling out of control, and expectancies of eating to alleviate boredom).</p> Methods <p>Participants included 161 adults (60.9% female; <i>M</i>_age= 31.6 years, <i>SD</i> = 10.73) who completed a baseline assessment for a randomized controlled trial examining a computer-delivered intervention for obesity and elevated AS.</p> Results <p>Results indicated that only AS social concerns was a statistically significant predictor for all three eating expectancies.</p> Conclusions <p>Individuals seeking treatment for weight-related concerns may benefit from screening and intervening on AS social concerns to change beliefs regarding the function of eating.</p>
