To design and validate a questionnaire to assess the level of knowledge regarding eating disorders in college students.
Observational, prospective, and longitudinal study, with the design of the questionnaire based on a conceptual review and validation by a cognitive pre-test and pilot test-retest, with analysis of the psychometric properties in each application.
University Foundation of Bages, Barcelona. Marco community care.
A total of 140 students from Health Sciences; 53 women and 87 men with a mean age of 21.87 years; 28 participated in the pre-test and 112 in the test-retests, 110 students completed the study.
Validity and stability study using Cronbach α and Pearson product-moment correlation coefficient statistics; relationship skills with sex and type of study, non-parametric statistical Mann-Whitney and Kruskal-Wallis tests; for demographic variables, absolute or percentage frequencies, as well as mean, central tendency and standard deviation as measures of dispersion were calculated. The statistical significance level was 95% confidence.
The questionnaire was obtained that had 10 questions divided into four dimensions (classification, demographics characteristics of patients, risk factors and clinical manifestations of eating disorders). The scale showed good internal consistency in its final version (Cronbach α=0.724) and adequate stability (Pearson correlation 0.749).
The designed tool can be accurately used to assess Health Sciences students' knowledge of eating disorders.
设计并验证一份问卷，以评估大学生对饮食失调症的认知水平。
观察性、前瞻性和纵向研究，问卷设计基于概念性综述，并通过认知预测试和试点重测进行验证，每次应用时分析其心理测量特性。
巴塞罗那巴耶斯大学基金会。马尔科社区护理中心。
共有140名健康科学专业的学生；53名女性和87名男性，平均年龄21.87岁；28人参加了预测试，112人参加了重测，110名学生完成了研究。
使用克朗巴哈α系数和皮尔逊积差相关系数统计进行效度和稳定性研究；研究性别和学习类型与关系技巧之间的关系，采用非参数统计的曼-惠特尼检验和克鲁斯卡尔-沃利斯检验；对于人口统计学变量，计算绝对或百分比频率，以及作为离散度测量指标的均值、集中趋势和标准差。统计显著性水平为95%置信度。
获得了一份包含10个问题的问卷，分为四个维度（分类、患者人口统计学特征、危险因素和饮食失调症的临床表现）。该量表在最终版本中显示出良好的内部一致性（克朗巴哈α系数=0.724）和足够的稳定性（皮尔逊相关系数0.749）。
所设计的工具可准确用于评估健康科学专业学生对饮食失调症的认知。
