Validation of a new screening questionnaire for disordered eating behaviors in men.

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 (n1 = 9 for interviews, n2 = 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, n1 = 297) and confirmatory factor analysis (CFA, n2 = 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. LEVEL OF EVIDENCE: Level V: Opinions of authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

The Spanish Validation of the Accommodation and Enabling Scale for Eating Disorders Among Carers: A Pilot Study.

Literature suggests that families may accommodate patients' symptoms in attempts to alleviate family conflict and stress. These accommodating and enabling behaviours may have a negative impact on carers and those they care for. There are no self-report questionnaires validated in Spanish to measure accommodation among relatives of patients with an eating disorder. The aim of this study was to examine the psychometric properties of the Spanish version of the Accommodation and Enabling Scale for Eating Disorders (AESED-S) among relatives of eating disorder patients. A cross-sectional study of 90 relatives was carried out to explore the factor structure, reliability and validity of the AESED-S. The internal consistency of the Spanish version of the AESED subscales was good, ranging from .89 to .81. The correlation of the five subscales with conceptually related measures (negative caregiving experience and distress) supports the convergent validity of this instrument in this sample. Results indicated that the Spanish version of the AESED provides a reliable and valid tool for assessing family accommodation in the context of having a relative with an eating disorder.
