Assessing alexithymia in French-speaking samples: psychometric properties of the Observer Alexithymia Scale-French translation

In the present study, we evaluated the psychometric properties of the Observer Alexithymia Scale-French translation (OAS-F), a 33-item, observer-rated alexithymia measure. The scale, accessible to lay and professional raters, taps everyday expressions of alexithymia. French university students (N = 159) were asked to rate a person they knew well or ask an acquaintance to rate them. Those being rated (N = 159) were parents, siblings, children, and friends. OAS-F total and subscale scores were comparable to those in the English normative samples. Moreover, OAS scores were reliable, and the scale's five-factor structure (distant, uninsightful, somatizing, humorless, and rigid) was confirmed. Importantly, too, OAS total scores correlated 0.31 with (self-report) 20-item Toronto Alexithymia Scale (TAS) scores. The OAS-F appears to be a psychometrically sound observer-rated alexithymia measure.
