OBJECTIVE: There are a subset of individuals with eating disorders (EDs) who do not overevaluate body shape/weight (i.e., nonfat phobic ED; NFP-ED). According to the transdiagnostic cognitive-behavioral conceptualization of EDs, a need for control, in general, is hypothesized as the core psychopathology of NFP-EDs, with shape- and weight-related motivations for ED behavior merely superimposed in FP-ED presentations. This study tested the need for control as motivation for restriction in NFP-ED, using items aimed at assessing control from the Eating Disorder Examination (EDE) Restraint scale.
METHOD: Females ages 13-27 years consecutively admitted to residential treatment completed the EDE, Eating Disorder Inventory-3 Drive for Thinness subscale (EDI-DFT), and other self-report measures of psychopathology. We included patients with DSM-5 EDs, but excluded patients with avoidant/restrictive food intake disorder. Twenty participants had NFP-ED (≤14 on EDI-DFT) and 124 had fatphobic ED (FP-ED; >14 on EDI-DFT).
RESULTS: NFP-ED scored significantly lower than FP-ED on EDE Restraint scale shape/weight [χ2 (1) = 10.73-35.62, p's < .01] and on control items [χ2 (1) = 10.72-20.62, p's < .01], in addition to scoring lower on measures of general psychopathology and impairment.
DISCUSSION: Findings suggest those with NFP-ED report lower psychopathology overall and the new EDE Restraint scale control items do not capture additional motivation for restriction beyond that captured in the original Restraint scale shape/weight items. Future research should examine whether this latter finding is due to a minimizing response style in NFP-ED, an incomplete capture of desire for control by the EDE assessment method, or indeed reflects that need for control does not motivate restriction in NFP-EDs.
