Translation and psychometric properties of the Kid's Eating Disorders Survey (KEDS)-Spanish version

Abstract

Introduction. Few studies have used standardized instruments for evaluate the psychopathology of the Eating Behavior Disorders (EBD) in child and adolescence.

Objective. The objective of this study was to determine the psychometric properties of the Kid's Eating Disorders Survey (KEDS)-Spanish version [Cuestionario infantil para trastornos de [a conducta alimentaria (CITCA)].

Method. The following instruments were applied to subjects aged 7-17 years: K-SADS-PL-MX, Eating Attitude Test-40 (EAT- 40) and CITCA (Spanish version of the KEDS).

Results. A total of 98 females, age 12.5 + 2.5 (7-17), participated. Cronbach's alpha coefficient for the total of the KEDS was 0.92. The scale items were grouped into two main components, which accounted for 74.4% of the variance. The convergent validity between the Spanish version of the KEDS and the EAT-40 was significant: r = 0.832 (p = 0.01). The criterion validity, on comparing the Spanish version of the KEDS with the K-SADS-PL-MX, was acceptable, with a r = 0.899 (p 0.01). The test-retest at 15 days was positive: r = 0.967 (p 0.01).
