Resumen:
Purpose The aim of this study was to develop an instrument to identify
disordered eating behaviors (DEB) in college men (hereafter, DEBM-Q).
Methods A two-stage project consisting of a diagnostic scale
construction (n(1) = 9 for interviews, n(2) = 9 for cognitive
laboratory) and a validation study with a cross-sectional sample (N =
570) was carried out. Both semi-structured interviews and a cognitive
laboratory with nine participants were conducted to obtain DEBM-Q items.
DEBM-Q was applied to 570 freshmen male in Mexico City. Psychometric
characteristics and internal consistency (Cronbach's alpha) were
analyzed. An item-total correlation value greater than 0.30 was
determined, and factor loads greater than 0.40 were considered valid.
Exploratory factor analysis (EFA, n(1) = 297) and confirmatory factor
analysis (CFA, n(2) = 273) were performed. Results Two fixed factors
explaining 55.08% of the total variance were extracted. Factor 1,
``Drive for Thinness'' (8 items), explained 30.84% of the variance,
whereas factor 2, ``Drive for Muscularity'' (8 items), explained
24.23% of the variance. Cronbach's alpha for the whole questionnaire
was 0.84. DEBM-Q was correlated with the Dutch Food Restriction Scale
(RS) (r = 0.52, p < 0.001), Eating Disorder Examination-Questionnaire
(EDE-Q) (r = 0.46, p < 0.001), Emotional Eating Scale (EES) (r = 0.18, p
< 0.001), and Negative Affect Subscale (PANAS-X) (r = 0.11, p < 0.005).
Conclusion DEBM-Q is a valid and practical short screening tool (16
items) allowing early identification of disordered eating in young men,
thereby facilitating clinical management.
