抑郁症的认知理论表明，情绪反应性自尊是一种认知反应模式，其中低自尊暂时依赖于悲伤程度，代表了抑郁症的脆弱性。很少有研究直接检验这一假设，特别是使用密集的数据收集方法（即经验采样）来捕获随着时间的推移自然展开的悲伤和自尊的时间动态。在这项研究中，我们使用参与者的智能手机来收集现实世界中三周内的多个每日悲伤和自尊评分。然后，我们应用动态因素模型来探索关于自尊对悲伤的时间依赖性（即情绪反应性自尊）及其与同时期（例如沉思、悲伤情绪持续性）和前瞻性（例如未来症状学）的抑郁脆弱性指数的关系的理论驱动假设。总之，表现出情绪反应性自尊的个体在基线时表现出更高水平的沉思，在三周内更持久地悲伤情绪，并且在三周结束时抑郁症状增加，高于自尊的特质样指数。本研究中采用的智能手机评估和个人分析的整合为推进抑郁症的研究和治疗提供了一条令人兴奋的新途径。
Cognitive theories of depression suggest that mood-reactive self-esteem, a pattern of cognitive reactivity where low self-esteem is temporally dependent on levels of sadness, represents vulnerability for depression. Few studies have directly tested this hypothesis, particularly using intensive data collection methods (i.e., experience sampling) required to capture the temporal dynamics of sadness and self-esteem as they unfold naturally, over time. In this study we used participants’ smartphones to collect multiple daily ratings of sadness and self-esteem over three weeks, in the real world. We then applied dynamic factor modeling to explore theoretically driven hypotheses about the temporal dependency of self-esteem on sadness (i.e., mood-reactive self-esteem) and its relationship to indices of depression vulnerability both contemporaneously (e.g., rumination, sad mood persistence) and prospectively (e.g., future symptomatology). In sum, individuals who demonstrated mood-reactive self-esteem reported higher levels of rumination at baseline, more persistent sad mood over three weeks, and increased depression symptoms at the end of three weeks above and beyond a trait-like index of self-esteem. The integration of smartphone assessment and person-specific analytics employed in this study offers an exiting new avenue to advance the study and treatment of depression.
