背景:当前和以前的运动员是饮食失调(DE)的高危人群之一,影响他们的饮食习惯,身体成分,在他们的运动生涯中和之后的表现和健康。该组很少有全面的DE筛选工具。为了帮助解决这个问题,本研究利用经典测试理论(CTT)和项目反应理论(IRT)的混合方法方法来开发和验证适用于当前和以前运动员的DE筛选工具。
方法:使用新的量表开发方法来开发和评估效度(内容,脸,跨文化,construct),测试-重测可靠性,内部一致性可靠性,一种新的DE量表的因子分析和Rasch分析。
结果:创建了一种新的经过验证的运动饮食失调(ADE)筛查工具,有17个项目和四个分量表(食品控制,暴饮暴食,身体控制,身体不满),具有0.91的内部一致性信度,优秀的内容和结构效度,0.97的组内相关系数和优异的Rasch模型拟合。
结论:ADE筛查工具已被双重开发用于研究目的,并作为临床适用的筛查工具,用于检测当前和以前的运动员中的DE,适用于跨运动类别的全球使用。不同的性别和竞争水平。
BACKGROUND: Current and former athletes are one of the most at-risk population groups for disordered eating (DE), impacting their dietary practices, body composition, performance and health during and following their athletic careers. Few comprehensive DE screening tools exist for this group. To help address this, the current study utilised a mixed-methods approach of Classic Test Theory (CTT) and Item Response Theory (IRT) to develop and validate a DE screening tool suitable for current and former athletes.
METHODS: Novel scale development methodologies were used to develop and assess the validity (content, face, cross-cultural, construct), test-retest reliability, internal consistency reliability, factor analysis and Rasch analysis of a new DE scale.
RESULTS: A new validated Athletic Disordered Eating (ADE) screening tool was created, with 17 items and four subscales (food control, bingeing, body control, body discontent), with an internal consistency reliability of 0.91, excellent content and construct validity, an Intraclass Correlation Coefficient of 0.97 and excellent Rasch model fit.
CONCLUSIONS: The ADE screening tool has been dually developed for research purposes and as a clinically applicable screening tool to detect DE in current and former athletes and is suitable for a global use across sporting categories, diverse genders and levels of competition.
