Purpose

The aim of this study was to investigate the psychometric properties and the factor structure of the Clinical Impairment Assessment 3.0 (CIA) utilizing a confirmatory factor analysis in a large clinical sample of ED patients.

Methods

A total of 260 patients between the ages of 18 and 45 who completed assessments in a partial hospitalization or residential treatment program at an ED treatment facility between December 2012 and December 2016 were included in the analyses. Assessment measures included the CIA, EDE-Q, BDI-II, WHODAS, and a demographic questionnaire.

Results

Results favored a bifactor model with a strong general factor and three unreliable subfactors. The CIA showed strong construct validity with other measures of ED pathology (EDE-Q) and health-related QoL (WHODAS). Furthermore, admission CIA scores were predictive of treatment outcomes.

Conclusions

The CIA assesses general psychosocial impairment, supporting the use of a total, but not subscale scores, among symptomatic ED samples in the United States.

临床进食障碍样本中临床障碍评估3.0(CIA)的因子结构和心理计量学特性

目的

这项研究的目的是通过对大量ED患者的临床样本进行验证性因子分析,研究临床减损评估3.0(CIA)的心理测量特性和因子结构。

方法

分析包括2012年12月至2016年12月之间在急诊治疗设施进行的部分住院或住院治疗计划中完成评估的260位年龄在18至45岁之间的患者。评估措施包括CIA,EDE-Q,BDI-II,WHODAS和人口统计问卷。

结果

结果青睐具有强通用因子和三个不可靠子因子的双因子模型。CIA与其他ED病理学(EDE-Q)和健康相关QoL(WHODAS)的测量结果均显示出较强的构建效度。此外,入院CIA评分可预测治疗效果。

结论

CIA评估了一般的心理社会障碍,支持在美国有症状的ED样本中使用总分而非分量表得分。
