Psychometric studies of eating disorder measures within bariatric surgery populations are limited.
To examine the interrater reliability and internal consistency of the Eating Disorder Examination (EDE) among patients before and after bariatric surgery.
Three clinical centers of the Longitudinal Assessment of Bariatric Surgery Research Consortium.
The EDE-Bariatric Surgery Version was administered and audio-recorded by trained interviewers before and at annual assessments after bariatric surgery. Approximately 20% of interviews were randomly selected for rating by a second interviewer. Reliability of the original and brief EDE subscales was examined.
Interrater reliability of the EDE subscales ranged from .86-.97 for the original subscales and .83-.95 for brief subscales before surgery, and .90-.98 for the original subscales and .92-.97 for brief subscales after bariatric surgery. Interrater agreement (based on kappa) was almost perfect for overeating and binge-eating behaviors and substantial for loss-of-control eating before surgery. Similar interrater agreements (based on kappa) were observed after surgery for subjective overeating and binge-eating episodes. Internal consistency of the subscale and global scores was variable, ranging from .41-.97.
Findings provide support of the interrater reliability of the EDE, albeit with variable internal consistency, before and after bariatric surgery. Despite support for trained raters to reliably assess EDE constructs, variability in internal consistency suggests that further psychometric testing and rigorous scale development of disordered eating may be needed for the bariatric surgery population.
在减重手术人群中,对饮食失调测量的心理测量研究有限。
在接受减重手术前后,检查饮食失调检查(EDE)在患者中的评分者间信度和内部一致性。
纵向评估减重手术研究联盟的三个临床中心。
在接受减重手术之前和每年评估时,由经过培训的访谈者使用 EDE-减重手术版本进行访谈并录音。大约 20%的访谈随机选择由第二位访谈者进行评分。检查了原始和简短 EDE 分量表的可靠性。
在接受减重手术之前,EDE 分量表的评分者间信度范围为原始分量表的.86-.97 和简短分量表的.83-.95,而接受减重手术之后则为原始分量表的.90-.98 和简短分量表的.92-.97。在接受减重手术之前,暴食和暴食行为的评分者间一致性(基于 Kappa)几乎为完美,而失控性进食的一致性则为实质性。在接受减重手术之后,相似的评分者间一致性(基于 Kappa)也适用于主观暴食和暴食发作。分量表和总分的内部一致性各不相同,范围从.41-.97。
研究结果为 EDE 在接受减重手术前后的评分者间信度提供了支持,尽管内部一致性存在差异。尽管有训练有素的评分者可以可靠地评估 EDE 结构,但内部一致性的变异性表明,对于减重手术人群,可能需要进一步进行心理测量测试和严格的障碍性进食量表开发。
