确定可靠有效地评估临床损伤的措施对于饮食失调（ED）的诊断和治疗具有重要意义。目前的研究检查了 ED 发病高风险女性的临床损伤评估 (CIA) 的心理测量特性。参与者为 543 名女性（20.6 ± 2.0 岁），她们被分为三个 ED 类别之一：临床 ED、ED 发病高风险和低风险控制。在高风险女性中，CIA 表现出较高的内部一致性 (α = 0.93) 和良好的收敛效度与饮食失调态度 (rs = 0.27–0.68，ps < 0.001)。对 CIA 判别有效性的检查显示，患有临床 ED 的女性中 CIA 总体评分最高 (17.7 ± 10.7)，其次是高风险女性 (10.6 ± 8.5) 和低风险对照女性 (3.0 ± 3.3) (p < 0.001)。报告 ED 精神病理学行为指数（客观和/或主观暴饮暴食、净化行为、强迫运动和 ED 治疗史）的高风险女性比没有此类指数的女性具有更高的 CIA 总体评分 (ps < 0.05)，表明标准有效性良好。这些数据为中央情报局在美国样本中建立了第一个规范。中央情报局在高风险女性中的心理测量是健全的，与低风险女性相比，这些人的损伤程度更高，这证实了早期干预工作的相关性。
Identifying measures that reliably and validly assess clinical impairment has important implications for eating disorder (ED) diagnosis and treatment. The current study examined the psychometric properties of the Clinical Impairment Assessment (CIA) in women at high risk for ED onset. Participants were 543 women (20.6 ± 2.0 years) who were classified into one of three ED categories: clinical ED, high risk for ED onset, and low risk control. Among high risk women, the CIA demonstrated high internal consistency (α = 0.93) and good convergent validity with disordered eating attitudes (rs = 0.27–0.68, ps < 0.001). Examination of the CIA's discriminant validity revealed that CIA global scores were highest among women with a clinical ED (17.7 ± 10.7) followed by high risk women (10.6 ± 8.5) and low risk controls (3.0 ± 3.3), respectively (p < 0.001). High risk women reporting behavioral indices of ED psychopathology (objective and/or subjective binge episodes, purging behaviors, driven exercise, and ED treatment history) had higher CIA global scores than those without such indices (ps < 0.05), suggesting good criterion validity. These data establish the first norms for the CIA in a United States sample. The CIA is psychometrically sound among high risk women, and heightened levels of impairment among these individuals as compared to low risk women verify the relevance of early intervention efforts.
