Self-esteem stability describes fluctuations in the level of self-esteem experienced by individuals over a brief period of time. In recent decades, self-esteem stability has repeatedly been shown to be an important variable affecting psychological functioning. However, measures of self-esteem stability are few and lacking in validity. In this paper, we present the Self-Esteem Stability Scale (SESS), a unidimensional and very brief scale to directly assess self-esteem stability. In four studies (total = 826), we describe the development of the SESS and present evidence for its validity with respect to individual outcomes (life satisfaction, neuroticism, and vulnerable narcissism) and dyadic outcomes (relationship satisfaction in self- and partner ratings) through direct comparisons with existing measures. The new SESS proved to be a stronger predictor than the existing scales and had incremental validity over and above self-esteem level. The results also showed that all cross-sectional measures of self-esteem stability were only moderately associated with variability in self-esteem levels assessed longitudinally with multiple administrations of the Rosenberg Self-Esteem Scale. We discuss this validity issue, arguing that direct and indirect assessment approaches measure relevant, yet different aspects of self-esteem stability.
自尊稳定性描述了个体在短时间内所体验到的自尊水平的波动。近几十年来，自尊稳定性一再被证明是影响心理功能的一个重要变量。然而，自尊稳定性的测量方法很少且缺乏效度。在本文中，我们提出了自尊稳定性量表（SESS），这是一个单维度且非常简短的量表，用于直接评估自尊稳定性。在四项研究（总计826人）中，我们描述了SESS的编制过程，并通过与现有测量方法的直接比较，展示了其在个体结果（生活满意度、神经质和脆弱型自恋）和二元结果（自我和伴侣评价中的关系满意度）方面的效度证据。新的SESS被证明比现有量表更具预测力，并且在自尊水平之外具有增量效度。结果还表明，所有自尊稳定性的横断面测量与通过多次施测罗森伯格自尊量表纵向评估的自尊水平变异性仅具有中等程度的相关性。我们讨论了这个效度问题，认为直接和间接评估方法测量的是自尊稳定性相关但不同的方面。
