To examine this question, a longitudinal study was conducted in12 female inpatients with AN (age M = 22.2, SE = 1.36), before (Time-1) and afterreaching a body mass index of >17.5 kg/m2 (Time-2). Intolerance of uncertainty (IU)was assessed via a decision-making task, the wheel of fortune (WOF). Weight gain atTime-2 was accompanied with significant changes in uncertainty-related performancecompared to Time-1 [(Time Uncertainty), p < 0.05]. At Time-1, reaction times (RTs)varied in function of uncertainty, while at Time-2, uncertainty did not modulate RTs.These findings support a change in decision-making under uncertainty with successfulweight-rehabilitation in AN. While IU was present in underweight patients, it becamenon-significant after weight restoration. application/pdf https://folia.unifr.ch/global/documents/308261 https://folia.unifr.ch/documents/308261/files/Piccolo_2019.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.3389/fpsyg.2019.02492 info:eu-repo/semantics/openAccess License undefined Frontiers in Psychology. - 2019, p. 1-5 Anorexia nervosa Intolerance of uncertainty Weight-restoration Longitudinal Eating disorders Remission General psychology info:eu-repo/classification/udc/159.9 Behavioral Responses to Uncertainty in Weight-Restored Anorexia Nervosa – Preliminary Results http://purl.org/coar/resource_type/c_6501
