Show moreObesity is one of the most rapidly emerging public health concerns whose prevalence far exceeds that of eating disorders (Hudson et al., 2007). As most obese individuals do not meet criteria for an eating disorder, emotional eating (EE) may be a more useful construct in understanding obesity more broadly. Anxiety sensitivity (AS) has been recognized as a transdiagnostic risk factor for a variety of problem behaviors including EE in obese individuals (Hearon et al., 2012). In addition, recent research has highlighted the mediating role of maladaptive responses to internal experiences in the association between AS and eating pathology (Anestis et al., 2008). Experiential avoidance (EA) is one such maladaptive response that has garnered attention for predicting maladaptive coping for a range of psychiatric conditions. To date, only one study has examined the relationship between AS and EE in obese individuals (Hearon et al., 2012). This study aims to replicate and extend their findings by examining the role of EA in this relationship. A sample of 127 obese patients without an eating disorder seeking weight-loss treatment completed questionnaires to assess emotional eating, experiential avoidance, and anxiety sensitivity. When controlling for gender, negative affect, and current psychiatric diagnosis and treatment, EA was found to fully mediate the relationship between AS and EE. There was a significant positive indirect effect (B = .285, CI95% = .155-.462) and a non-significant direct effect (B = .039, p = .786. These findings provide initial support for the mediating role of EA in the association between AS and EE in an obese, non-eating disordered, weight-loss treatment-seeking sample.Further, the identification of AS and EA as relevant in the development of emotional eating adds to the growing literature base arguing for the conceptualization of these two factors as transdiagnostic risk factors for a wide range of problem behaviors, including emotional eating. Clinical and research implications are discussed, as well as strengths and limitations of the study. Recommendations for the development of interventions targeting individuals high in anxiety sensitivity, with the intention of reducing experiential avoidance, are also reviewed.Further, the identification of AS and EA as relevant in the development of emotional eating adds to the growing literature base arguing for the conceptualization of these two factors as transdiagnostic risk factors for a wide range of problem behaviors, including emotional eating.
