Repetitive negative thinking (RNT) is considered a transdiagnostic variable underlying common symptoms (e.g., depressed mood) across various mood disorders. Depressive rumination is one typical and frequent manifestation of RNT and is a well-known vulnerability factor of depression onset, maintenance and recurrence. Due to the time-related constraints in assessment settings and the association of rumination on sadness with diagnosis of depression, the rapid identification of individuals scoring high on this construct may become a useful screening tool in non-clinical samples. The main aim of the present study was to test the psychometric properties of the Spanish version of the Short Depressive Rumination Scale (SDRS) in a large sample (N = 649). Confirmatory Factor Analysis supported a one-factor model accounting for 75% of variance with an excellent internal consistency (α = .93) in spite of the reduced number of items (4 items). Criterion validity results based on associations with other well-established rumination (sub)scales, age, scores in depression and gender differences, were congruent. The results suggest that the SDRS, the shortest existing scale assessing depressive rumination to our knowledge, can be a useful instrument for a rapid assessment of depressive rumination in community samples.
反复消极思维（RNT）被认为是各种情绪障碍中常见症状（如情绪低落）背后的一个跨诊断变量。抑郁沉思是RNT的一种典型且常见的表现形式，是抑郁症发作、维持和复发的一个众所周知的易感性因素。由于评估环境中与时间相关的限制以及沉思与悲伤和抑郁症诊断之间的关联，快速识别在这一构念上得分高的个体可能会成为非临床样本中的一种有用筛查工具。本研究的主要目的是在一个大样本（N = 649）中检验西班牙语版简短抑郁沉思量表（SDRS）的心理测量特性。验证性因素分析支持一个单因素模型，该模型解释了75%的方差，尽管项目数量减少（4个项目），但其内部一致性极佳（α = .93）。基于与其他成熟的沉思（子）量表、年龄、抑郁得分和性别差异之间关联的效标效度结果是一致的。结果表明，就我们所知，SDRS是评估抑郁沉思的现有最短量表，它可以作为一种有用的工具，用于快速评估社区样本中的抑郁沉思。
