The aim of this study was to develop a new mood induction procedure in which a positively and a negatively loaded images presented sequentially (or vice versa) alter participants' mood state. A second objective was to investigate whether baseline results can be replicated at 6 months and whether these induced mood changes depend on sex, age, and image quality (colour and recognition). 82 participants underwent a mood induction procedure at baseline and 6 months. After a measurement in which current happiness, sadness and anger was assessed, they were exposed to two subsequent images of opposite emotional loading. After each image, they were asked to report their mood. Multi-level analyses showed significant effects of both the first image and the second image on participants' mood. Replication at 6 months was mostly confirmed. Interactions with sex and age were demonstrated partially. No significant colour and recognition effects were found. Unexpectedly, significant order effects of emotional loading were found for all three mood items. This redesigned mood induction procedure resulted in congruent effects on subjective mood. The need for replication of these findings, as well as the extension of the paradigm to clinical populations, is encouraged.
本研究的目的是开发一种新的情绪诱导程序，其中依次呈现（或反之亦然）具有正向和负向情感负荷的图像会改变参与者的情绪状态。第二个目标是调查基线结果在6个月时是否能够被复制，以及这些诱导的情绪变化是否取决于性别、年龄和图像质量（颜色和识别度）。82名参与者在基线和6个月时接受了情绪诱导程序。在评估了当前的幸福、悲伤和愤怒程度后，他们依次观看了两张具有相反情感负荷的图像。在每张图像之后，他们被要求报告自己的情绪。多层次分析显示，第一张图像和第二张图像对参与者的情绪均有显著影响。6个月时的复制结果大多得到证实。部分证实了与性别和年龄的交互作用。未发现颜色和识别度的显著影响。出乎意料的是，在所有三个情绪项目上均发现了情感负荷的显著顺序效应。这种重新设计的情绪诱导程序对主观情绪产生了一致的影响。鼓励对这些发现进行重复验证，并将该范式扩展到临床人群。
