non-invasive cranial electrical stimulation for mealtime anxiety in adults with eating disorders

Conditions: Eating Disorders; Anxiety

Summary: the study is to evaluate the feasibility of using a non-invasive brain stimulation device in a sample of inpatients with eating disorders (ed). the study will help researchers evaluate whether their device protocol is practical for eating disorder inpatients as a way to manage eating disorder and anxiety symptoms. a secondary aim of the study is to evaluate preliminary effectiveness of the protocol for reducing pre-meal anxiety during the treatment, and explore effects on eating disorder symptoms over the course of the inpatient admission.

evaluate the feasibility and acceptability of a protocol for using alpha-stim aid® (explicitly references the patented waveform and delivery method in the alpha-stim aid® device manufactured and marketed by electromedical products international, mineral wells, tx) to manage acute pre-meal anxiety in eating disorder inpatients indicated by recruitment and retention, dropout reasoning, nature and frequency of patient-reported side effects, level of missing patient-reported data, staff perception and patient perception. secondary outcomes include pre-meal anxiety rated on a 0-10 visual analogue scale, eating disorder symptom severity during the three-session protocol and across the inpatient admission using the eating disorder-15 assessment, and clinical impairment from disordered eating using the clinical impairment assessment-eating only version, across the same timepoints.
