The Comprehensive and Continuous Tool to Assess Severity and Improvement of Eating Disorders (CONTASI-ED) was developed to address limitations in existing assessments by incorporating behavioral, cognitive, and physiological markers. Objectives: This study aimed to examine the psychometric properties and sensitivity to symptom changes of the CONTASI-ED in a community-based clinical sample of women with ED. Methods: Participants were 58 females diagnosed with EDs and 10 healthy controls. The CONTASI-ED assessments were conducted over multiple time points in outpatient and intensive treatment settings. We examined reliability, validity, and sensitivity to treatment-related change. The CONTASI-ED scores were compared with EAT-26, and multivariable analyses explored the effects of body mass index (BMI), age, and post-traumatic stress disorder (PTSD) on symptom trajectories. Results: The CONTASI-ED demonstrated strong reliability, with test\u2013retest correlations between 0.72 and 0.90 and inter-rater reliability of 0.68\u20130.95. The tool effectively distinguished ED patients from healthy controls (p &lt; 0.001) and correlated strongly with EAT-26. Significant reductions in the CONTASI-ED scores over time (p &lt; 0.001) reflected treatment-related improvements\u2014although temporary score increases highlighted greater self-awareness and symptom disclosure. BMI, age, and PTSD significantly influenced symptom severity and treatment response. Conclusions: The CONTASI-ED demonstrated strong reliability and validity in distinguishing clinical and non-clinical cases and in tracking treatment-related changes. However, the findings are based on a relatively small, all-female sample, underscoring the need for further validation in more diverse populations.<\/jats:p>","DOI":"10.3390\/nu17111790","type":"journal-article","created":{"date-parts":[[2025,5,25]],"date-time":"2025-05-25T20:16:22Z","timestamp":1748204182000},"page":"1790","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["The Conclusive and Continuous Tool to Assess Severity and Improvement of Eating Disorders (CONTASI-ED): Development and Psychometric Properties"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3798-1741","authenticated-orcid":false,"given":"Moria","family":"Golan","sequence":"first","affiliation":[{"name":"Department of Nutritional Sciences, Tel Hai College, North Galilee, Qiryat Shemona 1220800, Israel"},{"name":"SHAHAF\u2014A Community-Based Facility for Treatment of Eating Disorders, Ganey Hadar 7683000, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roni","family":"Sides","sequence":"additional","affiliation":[{"name":"SHAHAF\u2014A Community-Based Facility for Treatment of Eating Disorders, Ganey Hadar 7683000, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keren","family":"Baum","sequence":"additional","affiliation":[{"name":"SHAHAF\u2014A Community-Based Facility for Treatment of Eating Disorders, Ganey Hadar 7683000, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rachel","family":"Arbib","sequence":"additional","affiliation":[{"name":"SHAHAF\u2014A Community-Based Facility for Treatment of Eating Disorders, Ganey Hadar 7683000, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wiessam","family":"Abu Ahmad","sequence":"additional","affiliation":[{"name":"Braun School of Public Health, Hebrew University-Hadassah, Jerusalem 91120, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"798","DOI":"10.1080\/10640266.2024.2328460","article-title":"The need for more inclusive measurement to advance equity in eating disorders prevention","volume":"32","author":"Alexander","year":"2024","journal-title":"Eat.
