This paper describes the psychometric evaluation of a new measure called the Power of Food Scale (PFS). The PFS assesses the psychological impact of living in food-abundant environments. It measures appetite for, rather than consumption of, palatable foods, at three levels of food proximity (food available, food present, and food tasted). Participants were(More)
An increasing proportion of human food consumption appears to be driven by pleasure, not just by the need for calories. In addition to its effects on body mass and health, the food environment in affluent societies may be creating an appetitive counterpart to the psychological effects of other hedonically-driven activities such as drug use and compulsive(More)
OBJECTIVE The objectives were to investigate the characteristics associated with frequent self-weighing and the relationship between self-weighing and weight loss maintenance. RESEARCH METHODS AND PROCEDURES Participants (n = 3003) were members of the National Weight Control Registry (NWCR) who had lost >or=30 lbs, kept it off for >or=1 year, and had been(More)
This study examined weight suppression (difference between highest premorbid weight and pretreatment weight) as a predictor of outcome in 188 outpatients with bulimia nervosa enrolled in a cognitive-behavioral therapy intervention. Participants who dropped out of treatment had significantly higher levels of weight suppression than treatment completers. Of(More)
OBJECTIVE The current study sought to examine executive function (EF) in overweight individuals with and without loss-of-control (LOC) eating. METHOD Eighty overweight and obese individuals entering a behavioural weight loss trial with (n=18) and without (n=62) LOC eating were administered a clinical interview and neuropsychological battery designed to(More)
Perceived deprivation describes a feeling of not eating what or as much as one would like, despite being in energy balance. This construct was previously found to correlate with the Restraint Scale in obese binge eaters and current dieters [Timmerman, G. M., & Gregg, E. K. (2003). Dieting, perceived deprivation, and preoccupation with food. Western Journal(More)
OBJECTIVE Obesity is largely attributable to excess caloric intake, in particular from "junk" foods, including salty snack foods. Evidence suggests that neurobiological preferences to consume highly hedonic foods translate (via implicit processes) into poor eating choices, unless overturned by inhibitory mechanisms or interrupted by explicit processes. The(More)
Bulimic individuals typically lose a substantial amount of weight in the process of developing their disorder. Such weight suppression (WS) may be behaviorally and metabolically problematic. The present study tested the hypothesis that WS would predict weight gain during the inpatient hospitalization of 146 bulimia nervosa-spectrum inpatients. WS(More)
OBJECTIVE Deficits in executive function (EF)-including inhibitory control, cognitive flexibility, decision-making, and working memory-may be risk or maintenance factors for binge eating disorder (BED). However, there is mixed evidence regarding EF deficits in individuals with BED. Significant methodological weaknesses (e.g., use of a single EF measure,(More)
The construct of disinhibition, as measured by the Eating Inventory, was recently found to have two factors: internal disinhibition (eating in response to cognitive and emotional cues) and external disinhibition (eating in response to environmental cues). This study examined whether early changes in disinhibition that occurred during a weight loss program(More)
