Abstract

Introduction: This study analysed the psychometric properties of the Reward Probability Index (RPI) in an online Colombian sample with 1129 participants. Method: To conduct a cross-validation study, the sample was randomly divided into two subsamples. An exploratory factor analysis was conducted with the first subsample yielding a two-factor structure. Then, the fit of this two-factor model was tested on the second subsample by conducting a confirmatory factor analysis. Results: This model obtained a good fit to the data and measurement invariance across gender was observed. The RPI also showed good internal consistency according to both Cronbach’s alpha and McDonald’s omega, scoring .88 in both cases. The RPI demonstrated convergent construct validity given its correlations with other related measures such as the Environmental Reward Observation Scale (r = .81), and the full version of the Behavioral Activation Scale for Depression (r = .71). Conclusions: The RPI showed good psychometric properties in this Colombian sample.

哥伦比亚样本中奖励概率指数的心理测量特性

本研究分析了1129名在线哥伦比亚参与者的奖励概率指数(RPI)的心理测量特性。方法:将样本随机分为两个子样本，进行交叉验证研究。探索性因子分析进行了第一个子样本产生双因素结构。然后，通过验证性因子分析，在第二个子样本上检验该双因素模型的拟合性。结果:该模型与数据拟合良好，且测量结果在性别间具有不变性。根据克朗巴赫的alpha和麦当劳的omega, RPI也显示出良好的内部一致性，两者的得分都是0.88。考虑到RPI与其他相关测量如环境奖励观察量表(r = 0.81)和抑郁症行为激活量表(r = 0.71)的相关性，RPI显示出收敛结构效度。结论:RPI在哥伦比亚样本中表现出良好的心理测量特性。

期刊介绍： Revista latinoamericana de Psicología (RLP) is a four month publication from Konrad Lorenz Fundación Universitaria. The RLP evaluates works that belong to one of the following categories: original papers (with empiric and new information) of many psychology fields (regardless of the methodology used) or qualitative/quantitative systematic reviews. Eventually it will be interested on works’ revision related to the development psychology tools or softwares, original methodology papers and researches which evaluate psychology from scientometry. The RLP is not interested in publishing non-systematic reviews or states of the art, case studies, protocols studies, hypothesis or papers proposals, letters, commentaries or essays, opinions articles, politics documents nor other sort of secondary literature. Traditionally, there have been monographics, books’ reviews and “others” published in “Mundo de la Psicología”, nevertheless these modalities will not be considered.
