The tendency to use pleasant states as a key criterion for how to structure daily life is called and has been measured with a 6-item scale. The Prioritizing Positivity Scale (PPS) is increasingly being used by researchers, but a comprehensive examination of its psychometric quality remains absent from the literature. Using three independent samples of adults (study 1: = 176, study 2: = 240, study 3: = 226), we tested the scale's (1) factor structure, (2) reliability, (3) convergent and discriminant validity, and (4) measurement invariance. Results suggested that the 6th item was problematic (low factor loading, conceptually distinct from other items) and when removed, a single-factor structure was appropriate. The revised 5-item PPS demonstrated satisfactory reliability, construct validity and measurement invariance. The revised 5-item PPS offers a brief and valid way to measure a personality difference shown to predict well-being.
将愉快状态用作构建日常生活的关键标准的倾向称为“积极取向”，并已通过 6 项量表进行了衡量。优先考虑积极性量表（PPS）越来越多地被研究人员使用，但该量表的心理测量质量仍缺乏全面的文献研究。本研究使用三个独立的成年人样本（研究 1：n=176，研究 2：n=240，研究 3：n=226），检验了该量表的（1）因子结构、（2）信度、（3）聚合和区别效度，以及（4）测量不变性。结果表明，第 6 项存在问题（因子负荷低，与其他项目在概念上不同），删除该项目后，适合采用单因子结构。经过修订的 5 项 PPS 具有令人满意的信度、结构效度和测量不变性。经过修订的 5 项 PPS 提供了一种简洁有效的方法，可衡量一种人格差异，这种差异被证明可以很好地预测幸福感。
