Se calculo alfa de Cronbach y omega de McDonald y se realizo un analisis factorial exploratorio con los diez incisos de la EDVC. El alfa de Cronbach fue 0,83 y la omega de McDonald, 084. La estructura interna mostro un unico factor que explico el 41,7% de la varianza total.

Valoración psicométrica de la Escala Breve para Racismo Moderno

Objective To find the internal consistency of the Modern Racism Scale (MRS) among medical students in Bucaramanga, Colombia. Methods A total of 352 medical students, mean age=20.0 years (SD=1.9) reported their attitudes towards Afro-Colombians; 59.4 % were women. Students completed the 10-item version of MRS. Cronbach alpha and McDonald omega were calculated. Exploratory factor analyses were done to propose a brief version of the MRS. Results The 10-item version showed a Cronbach alpha of 0.48 and a McDonald omega of 0.15. The short version, the Brief Modern Racism Scale (BMRS) (items 1, 4, 5, 7 and 8) presented a Cronbach alpha of 0.64 and McDonald omega of 0.65. The BMRS showed one salient factor responsible of 41.6 % of the total variance. Conclusions A Spanish-language short version of the MRS shows better psychometric performance than the original version. Further study is needed to corroborate these findings or make adjustments for Colombian cultural regions.

Cuestionario SCOFF para tamizaje de trastornos de la conducta alimentaria: Consistencia interna en estudiantes de un colegio de Cartagena, Colombia.

Background: The SCOFF questionnaire for screening eating disorders is criterion validated among female adolescent students from Bucaramanga, Colombia. However, the psychometric properties of a scale vary according to the population, and internal consistency of the SCOFF questionnaire is not known in Colombian Caribbean students. Objective: To know the internal consistency of the SCOFF questionnaire for gender among school attending adolescents of a school settled in low-income area at the city of Cartagena, Colombia. Method: A total of 416 students aged 13-17 years old filled-out the SCOFF questionnaire in the classroom, mean age 14.6 years for girls and 14.8 years, for boys. The SCOFF questionnaire is a five-item scale that inquires about make yourself sick, lost control, lost more than one stone in three months, believe yourself fat, food dominates the life. Kuder-Richardson’s formula 20 was computed to know the internal consistency. Results: For girls, the internal consistency of the SCOFF questionnaire was 0.343, and for boys, 0.209. Girls pointed higher than boys in make yourself sick, lost control and believe yourself fat; and boys higher than girls in food dominates the life (p<0.05). Conclusions: The internal consistency of the SCOFF questionnaire is poor among adolescent students dwelling in a lowincome area of this city. It is necessary to rely on a tool with better psychometric properties for this population.
