Abstract

OBJECTIVE: This study compares different problematic eating behaviors (PEBs; objective [OBE]/subjective [SBE] binge-eating and compulsive [CG]/noncompulsive [NCG] grazing) in relation to the severity of loss of control (LOC) and psychopathology. We also investigate LOC as a mediator between PEBs and psychopathology. METHOD: This cross-sectional study assessed a group of patients before bariatric surgery (n = 163), and a group of bariatric patients 12 months or more after surgery (n = 131). Face-to-face assessment: Eating Disorders Examination for binge-eating episodes; Rep(eat) for grazing. LOC was measured by five questions answered in a 5-point Likert scale. Self-report measures: disordered eating, grazing, negative urgency, depression, anxiety, and stress. RESULTS: OBEs were reported by 26(8.8%), SBE by 29(9.8%), CG by 35(11.9%), and NCG by 36(12.2%) of patients. The different PEBs differed significantly in the severity of LOC (F(3,120)= 25.81, p < .001). Patients reporting OBEs scored higher and patients with NCG scored lower in most measures than patients with other PEBs. Patients with any PEBs scored higher in all self-report measures than those not reporting any PEBs, with statistical significance reached for uncontrolled eating (F(4,288)= 20.21, p < .001), emotional eating (F(4,288)= 23.10, p < .001), repetitive eating F(4,288)= 18.34, p < .001), and compulsive grazing (F(4,288)= 27.14, p < .001). LOC was found to be a full mediator between PEBs and psychopathology. DISCUSSION: There is no evidence that the different PEBs differ in the psychopathology severity, independently of the experience of LOC eating during the eating episodes. We show evidence for the conceptualization of different PEB, including grazing, on a continuous scale of LOC and psychopathology.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
