2023 Outpatient Clinical Outcomes and Key Findings

Behavior and Symptom Identification Scale (BASIS-24)

The Odyssey Outpatient Network uses BASIS-24 to identify a wide range of symptoms across the diagnostic spectrum. Using a five-point Likert scale, the 24 questions are scored using a weighted average algorithm that gives an overall score and scores for six subscales that cover the following domains: depression, relationships, self-harm, emotional liability, psychosis, and substance abuse. The questionnaire was administered at admission, mid-treatment or every 30 days, and again at discharge.

Eating Attitudes Test (EAT-26)

Additionally, Odyssey’s Aster Springs Outpatient clinics use EAT-26, a leading standardized self-report measure of eating disorder symptoms and concerns. Using a six-point Likert scale in conjunction with additional measures assessing behavioral symptoms and body mass index (BMI), the assessment gives an overall score and scores for three subscales. The subscales cover the following domains: dieting which measures how much someone, motivated by a desire to be thinner, scrutinizes calorie content, carbohydrates, and sugar content, Bulimia and Food Preoccupation which assesses someone’s tendency to purge after meals and excessive food-related thinking, and Oral Control which identifies a person’s tendency toward needing less self-control over their eating.
