Abstract

The aim of the study is to assess the psychometric properties of the Portuguese version of the 18-items Dysfunctional Attitudes Scale (Form B) in a Portuguese sample of people aged 60 and over. Background: The 18-item Dysfunctional Attitudes Scale (Form B) is an instrument for assessing dysfunctional attitudes and can be useful as a predictor of depression for both initial episodes and relapses Methods: This was a one-stage cross-sectional survey of Portuguese-speaking people aged 60 years and over, able to read and write, functionally autonomous, and living in the community in their usual residences. The instrument was evaluated for its psychometric properties. Convergent validity with the Beck Depression Inventory-II was assessed. Results: The Portuguese version of the 18-item Dysfunctional Attitudes Scale (Form B) was structured into three factors, which explained a total of 58.95% of the total variance of the instrument. The exploratory factor analysis resulted in a modified model in which three factors were obtained with an eigenvalue greater than one (Kaiser's criterion). Three factors were obtained instead of two as in the original study. It showed an internal consistency (Cronbach's alpha = 0.770) and an interclass correlation coefficient ranging from 0.166 to 0.449, and the overall convergent validity with the Beck Depression Inventory-II was considered good; Conclusions: The Portuguese version of the Dysfunctional Attitudes Scale (DAS-18B) of people aged 60 and over demonstrated good psychometric properties.

在葡萄牙 60 岁及以上人群样本中评估 18 项功能失调态度量表(表格 B)的心理测量特性。
本研究旨在评估葡萄牙语版 18 项功能失调态度量表(表格 B)在葡萄牙语 60 岁及以上人群样本中的心理测量特性。研究背景:18 项功能失调态度量表(表格 B)是一种评估功能失调态度的工具,可作为抑郁症初发和复发的预测指标:这是一项单阶段横断面调查,调查对象为 60 岁及以上、能够读写、功能自主、在社区常住的葡萄牙人。我们对该工具的心理测量特性进行了评估。同时还评估了与贝克抑郁量表-II的一致性。结果显示葡萄牙语版的 18 项功能失调态度量表(表格 B)分为三个因子,共解释了该工具 58.95% 的总方差。探索性因子分析得出了一个修正模型,其中有三个因子的特征值大于 1(凯撒标准)。得到了三个因子,而不是最初研究中的两个因子。该模型的内部一致性(Cronbach's alpha = 0.770)和类间相关系数从 0.166 到 0.449 不等,与贝克抑郁清单-II 的总体收敛效度被认为是良好的;结论:葡萄牙语版 60 岁及以上老年人功能失调态度量表(DAS-18B)具有良好的心理测量学特性。
