OBJECTIVES: Our objectives were to evaluate the psychometric properties of the
Observer Alexithymia Scale (OAS) in eating disorder patients, alexithymia
severity across diagnostic subgroups, and correspondence among three alexithymia
METHOD: Seventy-five women, each with an eating disorder diagnosis, completed
two alexithymia self-reports, the 20-item Toronto Alexithymia Scale (TAS-20) and
the Bermond-Vorst Alexithymia Questionnaire-version B (BVAQ-B), and asked a
relative or an acquaintance to rate them using the OAS.
RESULTS: The OAS showed acceptable discriminant validity and interrater
reliability. Patients’ OAS scores were higher than scores reported for
people-in-general samples and lower than those for outpatient clinical samples.
No statistically significant OAS, TAS-20, and BVAQ-B score differences were
found between the patients with anorexia nervosa restrictive type and those with
bulimia nervosa. OAS, TAS-20, and BVAQ-B total scores were moderately,
positively, and significantly correlated.
CONCLUSION: These clinical data show the psychometric strength of the OAS, which
reasonably can be recommended for use with the TAS-20 in research and clinical
