Abstract

The purpose of this study was to evaluate the internal consistency, factor structure, and validity of the Leiden Index of Depression Sensitivity-Revised (LEIDS-R) and a recent revision of the LEIDS-R (LEIDS-RR) in Norway. The LEIDS-R is a self-report inventory measuring cognitive reactivity. Cognitive reactivity is defined as the relative ease with which negative thinking is activated by mild low mood and has been shown to be a strong predictor of relapse of depression. Hospital employees and psychology students (N = 240) completed the LEIDS-R and measures of depression, repetitive negative thinking, and mindfulness. The results showed that Cronbach’s alpha was equally high for both the LEIDS-R and LEIDS-RR total score (α = .92), indicating good internal consistency. Confirmatory factor analysis of the LEIDS-R suggested an acceptable model fit for the original first-order six-factor model. Confirmatory factor analyses of the LEIDS-RR suggested the best fit for a bifactor five-factor model. Correlational analyses showed positive associations of the LEIDS-R and LEIDS-RR scales with depression and repetitive negative thinking and negative relationships with mindfulness. It is concluded that the Norwegian versions of the LEIDS-R and LEIDS-RR appear to be both reliable and valid for future use.

摘要

这项研究的目的是评估挪威的莱顿抑郁敏感性修订版（LEIDS-R）和LEIDS-R（LEIDS-RR）的最新修订版的内部一致性，因子结构和有效性。LEIDS-R是一种自我报告清单，用于测量认知反应性。认知反应性被定义为轻度情绪低落引起的负面思考的相对容易程度，并且已被证明是抑郁症复发的有力预测指标。医院员工和心理学专业的学生（N  = 240）完成了LEIDS-R并评估了抑郁，重复性负面思维和正念的程度。结果显示，LEIDS-R和LEIDS-RR总分的Cronbach's alpha值均很高（α= 0.92），表明内部一致性良好。对LEIDS-R的验证性因子分析表明，该模型适合原始一阶六因子模型。LEIDS-RR的验证性因素分析表明，最适合双因素五因素模型。相关分析显示，LEIDS-R和LEIDS-RR量表与抑郁症和重复性否定性思维以及与正念的消极关系呈正相关。结论是挪威版本的LEIDS-R和LEIDS-RR似乎既可靠又有效，可供将来使用。
