The objective of this study is to validate the Catalan version of the SCOFF questionnaire with a community sample of adolescents.
This study used a community sample of 954 participants (475 girls and 479 boys; aged between 10.9 and 17.3 years and from the city of Barcelona) and a risk group of 78 participants (35 men and 43 women; derived from the community sample) that have exceeded > or =95 percentile in at least two of the three scales of the Eating Disorders Inventory-2 (EDI-2): Drive for Thinness, Bulimia, and Body Dissatisfaction.
There were significant differences in total SCOFF scores across gender and school grades. The SCOFF best cutoff point was 2 (sensitivity=73.08%; specificity=77.74%). Concurrent validity with the EDI-2 varied between low and moderate. The reliability of the SCOFF questionnaire was moderate. Exploratory factor analysis of the SCOFF questionnaire showed a two-factor structure for the total sample and for girls, and one factor for boys.
The best cutoff point for this community sample is 2. The data suggest that the SCOFF questionnaire could be a useful screening questionnaire to enable the detection of groups possibly at risk for eating disorders among adolescent Spanish community samples.
本研究旨在对加泰罗尼亚语版SCOFF问卷在青少年社区样本中进行验证。
本研究采用了一个由954名参与者组成的社区样本（475名女孩和479名男孩；年龄在10.9至17.3岁之间，来自巴塞罗那市）以及一个由78名参与者组成的风险组（35名男性和43名女性；来自社区样本），这些参与者在进食障碍问卷-2（EDI-2）的三个量表（追求瘦身、暴食症和身体不满）中至少有两个量表得分超过或等于第95百分位数。
SCOFF总分在性别和年级之间存在显著差异。SCOFF的最佳截断点为2（灵敏度=73.08%；特异度=77.74%）。与EDI-2的同时效度在低到中等之间变化。SCOFF问卷的信度为中等。对SCOFF问卷进行探索性因子分析，结果显示总样本和女孩的问卷呈两因素结构，男孩的问卷呈单因素结构。
该社区样本的最佳截断点为2。数据表明，SCOFF问卷可能是一种有用的筛查问卷，有助于在西班牙青少年社区样本中检测出可能存在进食障碍风险的群体。
