“…It has shown excellent validity in a clinical population 11 and reliability in a student population. 16 The SCOFF tool also performed well against 10 questions set by Greenhalgh 17 to assess screening tests. It has been found to be reliable and replicable when administered as a written questionnaire rather than when undertaken as an oral interview, and may even provide enhanced disclosure of symptoms due to the less intimidating approach.…”

T. Feasibility and acceptability of screening for eating disorders in primary care. Family Practice 2007; 24: 511-517. Background. Earlier diagnosis of disordered eating is linked to improved prognosis, but detection in primary care is poor.Objectives. To assess the feasibility of screening for disordered eating within primary care, in terms of the proportion of patients accepting screening, yield of cases, action taken by staff and staff views on screening. Methods. Data were collected in open GP surgeries, midwife (MW) antenatal clinics and health visitor (HV) child health surveillance clinics in two GP practices, using face-to-face surveys and semi-structured interviews. Female patients aged 16-35 were asked to complete the SCOFF questionnaire, which was scored by researchers and taken by the patient into their consultation. If the result indicated possible disturbed eating, the health professional (HP) running the surgery/ clinic was asked to complete a questionnaire and interview. One hundred and eleven women were screened and 11 HPs (GPs, MWs, HVs) were interviewed.Results. Forty-six percent of patients agreed to be screened. Of these, 16% produced a positive result. The staff survey suggested that HPs found screening acceptable. However, concerns arose in the interviews, principally over what action to take in response to positive results. Positive results were rarely recorded in medical notes, and treatment was rarely offered. Conclusion. In order for a screening programme for eating disorders to be implemented in primary care, HP concerns about options for dealing with positive results would need to be addressed. Feasibility of screening would be enhanced by production of a protocol to be followed in the case of positive results.

“…[6][7][8] Within the eating disorders literature some researchers have found patterns of data that are consistent with the hypothesis that anonymity does indeed increase levels of honest responding. 9,10 In fact, it has been argued that the higher rates of eating disorder pathology routinely found via selfreport versus interview 9,[11][12][13][14] may be the result of individuals' unwillingness to disclose problematic behaviors in face-to-face interviews. 11,14 The present study was designed to extend the literature on the effects of anonymity and response format on endorsement of eating disorders symptoms by comparing a standard self-report assessment methodology to a novel assessment methodology that allowed for true anonymity in responding.…”

Objective: The present study was designed to compare response rates on a standard self-report questionnaire that was nominally anonymous to an unmatched count questionnaire that allowed for true anonymity in responding.Method: Four hundred and fifty-four college students were asked about several topics, including attitudes towards weight and shape, dieting, and eating disordered behavior using one of two response formats; either a standard questionnaire in true-false format or an unmatched count questionnaire that did not require participants to directly answer sensitive questions.Results: Both males and females had significantly different rates of endorsement between the two methods of assessment on the majority of the eating-related questions.Conclusion: Response format and degree of anonymity affect endorsement of eating-related thoughts and behaviors. Understanding response bias is critical to determining accurate rates of eating disordered thoughts and behaviors. V

Introducción. La prevalencia de los trastornos de la conducta alimentaria ha aumentado en los últimos años, creando la necesidad de detectar precozmente los casos en poblaciones en riesgo. Objetivo. Determinar la consistencia interna, la reproducibilidad y la validez de criterio del cuestionario SCOFF (del acrónimo en inglés, sick, control, one, fat, food) en universitarias para el tamizaje de los trastornos de la conducta alimentaria. Materiales y métodos. Se llevó a cabo un estudio de validación con muestreo transversal al azar de 385 estudiantes entre 1.587 elegibles de 6 facultades de la Universidad Autónoma de Bucaramanga, Colombia. Se aplicó de manera independiente el cuestionario SCOFF y la entrevista diagnóstica internacional compuesta. Resultados. 149 (38,7%) estudiantes fueron positivos en la puntuación del cuestionario SCOFF para los trastornos de la conducta alimentaria. La sensibilidad fue de 78,4% (IC95%, 64,3%-88,2%), la especificidad de 75,8% (IC95%, 68,9%-81,6%), el valor pronóstico positivo de 46,5% (IC95%, 35,8%-57,5%) y el valor pronóstico negativo de 92,9% (IC95%, 87,3%-96,2%). El área bajo la curva ROC fue de 0,823 (IC95%, 0,760-0,887), el alfa de Cronbach de 0,480 y la kappa media de Cohen de 0,433 (IC95%, 0,315-0,552). La concordancia prueba-reprueba fue de 91,6% (IC95%, 85,5%-95,7%). Conclusión. El cuestionario SCOFF parece ser una buena alternativa como instrumento de tamizaje para detectar los trastornos de la conducta alimentaria en mujeres universitarias de Colombia, por su sencillez y rapidez de administración.Palabras clave: anorexia nerviosa, bulimia nerviosa, trastornos de la conducta alimentaria, cribado, validez, reproducibilidad de resultados. Validation of the SCOFF questionnaire for screening of eating disorders in university womenBackground. The prevalence of eating disorders has been steadily increasing in recent years. This has led to a growing sense that instruments are necessary for early detection in high risk populations. Objective. Herein the SCOFF (sick, control, one, fat, food) questionnaire was examined for its internal consistency, reliability, and criterion validity in screening eating disorders among university women. Materials and methods. A sample of 385 students was selected at random from six schools in the Universidad Autónoma de Bucaramanga, Colombia, and were evaluated independently with the SCOFF questionnaire and a CIDI (Composite International Diagnostic Interview). Results. A total of 149 (38.7%) students were positive for eating disorder syndromes according to the SCOFF questionnaire, whereas 82 (21.2%) students met eating disorder using the CIDI. SCOFF questionnaire sensitivity was 78.4% (95%CI 64-88%), specificity 75.8% (95%CI 69-82%), ROC curve area 0.823 (95%CI 0.76-0.89), Cronbach s alpha 0.480, Cohen s kappa 0.433 (95%CI 0.32-0.55), and test-retest concordance 91.6% (95%CI 86-96). Conclusion. These data indicate the SCOFF questionnaire to be a good scale in screening for eating disorders among university women. Its added advantages are that th...
