Abstract
Objective
The Eating Disorder-15 (ED-15) is a brief measure developed for the routine assessment of eating disorder (EDs), despite its use in research settings having increased over the last few years. To assess the psychometric properties of the ED-15 in a nonclinical sample of Chilean women.
Method
A multicultural Spanish-language version was developed through combined translation techniques. University female students (N = 380) (M
age 22.32, SD = 2.48) were recruited through social media. After providing their informed consent, participants completed a battery of questionnaires online.
Results
A bi-factor model replicating the bi-factor structure and providing support for the general factor showed the best fit to the data. Moderate-to-strong correlations with measures of EDs, physical comparison, body appreciation, social physique anxiety, and depressive symptoms are presented as evidence of concurrent and convergent validity. Items analyses revealed strong correlations between manifest variables, their correspondent latent variable and the general factor (r
s = .60 to .89, ps < .001). Additionally, current findings provide support for the internal consistency of the scale (Cronbach’s alpha and Omega values were ≥ .80) and test–retest reliability (ICCs = .84 to .89, ps < .001).
Discussion
Like previous findings, the current study provides validity to the original bi-factor structure of the ED-15 and additional validity to a general factor. The availability of this multicultural Spanish-language version would provide session-by-session assessment, providing crucial information throughout treatment. Also, the availability of the current measure would contribute to further research efforts in a yet understudied population such as Hispanic women.
Public Significance
The Eating Disorder-15 (ED-15) is a promising measure meant to assess session-by-session change for clinical and research purposes. The availability of a Multicultural Spanish language version of the ED-15 allows for routine clinical assessment and represents a contribution for research efforts in a yet understudied populations such as Hispanic women.
Resumen
Objetivo
El Eating Disorder-15 (ED-15) es una breve medida de trastornos alimentarios (TCA) diseñada para realizar una evaluación rutinaria, a pesar de que su uso en la investigación ha crecido en los últimos años. Evaluar las propiedades psicométricas del ED-15 en una muestra no clínica de mujeres chilenas.
Método
Se desarrolló una versión multicultural al español mediante técnicas de traducción combinadas. Las estudiantes universitarias (N = 380) (M
edad 22.32, DT = 2.48) fueron reclutadas en redes sociales. Después de dar su consentimiento, las participantes completaron cuestionarios en línea.
Resultados
un modelo bifactorial que replica la estructura de dos factores y proporciona soporte para un factor general mostró el mejor ajuste. Correlaciones moderadas a fuertes con medidas de TCA, comparación física, apreciación corporal, ansiedad social física y síntomas depresivos se presentan como evidencia de validez concurrente y convergente. Análisis de ítems revelaron fuertes correlaciones entre las variables manifiestas, su correspondiente variable latente y el factor general (r
s = .60 a .89, ps < .001). Los hallazgos actuales respaldan la consistencia interna (alfa Cronbach y Omega > .80) y la confiabilidad test–retest (ICC = .84 a .89, ps < .001).
Discusión
El estudio actual proporciona validez a la estructura original de 2 factores del ED-15 y validez adicional a un factor general. La disponibilidad de esta versión multicultural en español permitirá una evaluación sesión por sesión, brindando información clínica crucial al tratamiento. Su disponibilidad permitirá el desarrollo de investigaciones en una población aún poco estudiada como la de mujeres latinas.
