The Anorectic Behaviour Observation Scale (ABOS) was designed to obtain information from relatives about behaviours and attitudes of patients with eating disorders (ED). The aim of this study was to validate the ABOS into Spanish.
We evaluated the psychometric characteristics of the Spanish version of the ABOS in a clinical ED sample (239 caregivers of 143 ED patients). Instrument reliability (internal consistency), validity (construct, convergent and discriminant, known groups), responsiveness and goodness-of-fit were measured.
Data from the Spanish population revealed a three-factor structure similar to that of the original ABOS, although the composition of subscales differed somewhat from the original. An ABOS cut-point of 21 was identified. The Cronbach's alpha coefficient for the total ABOS score was 0.81. Correlations with other instruments demonstrated convergent and divergent validity. Among caregivers, the total ABOS score and Factor scores significantly discriminated between anxiety, depression and health-related quality of life, while among ED patients they discriminated between diagnosis, severity and level of ED symptoms - evidence of known-groups validity.
These findings suggest that the ABOS can be reliably and validly used in Spain in a number of different clinical contexts, by researchers and clinicians alike.
厌食行为观察量表（ABOS）旨在从亲属那里获取有关饮食失调（ED）患者行为和态度的信息。本研究的目的是将ABOS验证为西班牙语版本。
我们在一个临床ED样本（143名ED患者的239名照料者）中评估了西班牙语版ABOS的心理测量特征。测量了工具的信度（内部一致性）、效度（结构效度、聚合效度和区分效度、已知群体效度）、反应度和拟合优度。
来自西班牙人群的数据显示出与原始ABOS相似的三因素结构，尽管子量表的组成与原始版本略有不同。确定了ABOS的切点为21。ABOS总分的克朗巴赫α系数为0.81。与其他工具的相关性证明了聚合效度和区分效度。在照料者中，ABOS总分和因子得分在焦虑、抑郁和健康相关生活质量方面有显著差异，而在ED患者中，它们在诊断、严重程度和ED症状水平方面有差异——这是已知群体效度的证据。
这些发现表明，研究人员和临床医生都可以在西班牙的许多不同临床环境中可靠且有效地使用ABOS。
