The present study investigated a dimensional model of eating pathology in a non-clinical sample. Common and distinct vulnerability factors based on personality and co-occurring psychopathology symptoms were investigated. The possible moderating effect of family environment on the relationship between distinct eating pathology and personality was tested. Four oblique dimensions emerged from EFA and CFA tests. The remaining analyses were performed using the Restraint Dimension and the Binge-Purge (BP) Dimension. Remaining hypotheses were tested using two subsets of the sample: the Full Sample and the Full Sample plus a small oversampling subset to increase sample variability. Using CFA, a dimensional model of eating pathology was identified using the Full Sample. Further, common co-occurring symptoms emerged for both dimensions including depression and anxiety. Distinct co-occurring symptoms also emerged, specifically, externalizing behaviors were associated with the BP Dimension and internalizing behaviors were associated with the Restraint Dimension. Using the MPQ-BF, personality patterns among the dimensions were less clear when higher order personality was examined; however, at the trait level, both dimensions were associated with Stress Reactivity whereas the Restraint Dimension was associated with Traditionalism and the BP Dimension was associated with Alienation. Support for the moderating effect of Family Environment, as measured by the FAD, was limited, but family enmeshment was found to moderate the relationship between personality Constraint and the Restraint Dimension. Use of the two sub-samples led to inconsistent findings in some areas. It is likely that inclusion of the oversampling group produced a sample from a population that is different than the populations from which the Full Sample was drawn. Focusing on results from the Full Sample only, the findings of the present study suggest that eating pathology may be dimensional in nature. This provides a useful way of exploring etiological and maintaining factors for eating problems. In addition, certain eating behaviors may have distinct vulnerability factors, and these vulnerability factors may have a common etiology with non-eating disorder symptoms such as depression or anxiety that co-occur with particular eating pathology. Finally, genetics may have greater etiological impact on eating pathology than family environment does.
