The Positivity Resonance Theory of coexperienced positive affect describes moments of interpersonal connection characterized by shared positive affect, caring nonverbal synchrony, and biological synchrony. The construct validity of positivity resonance and its longitudinal associations with health have not been tested. The current longitudinal study examined whether positivity resonance in conflict interactions between 154 married couples predicts health trajectories over 13 years and longevity over 30 years. We used couples' continuous ratings of affect during the interactions to capture coexperienced positive affect and continuous physiological responses to capture biological synchrony between spouses. Video recordings were behaviorally coded for coexpressed positive affect, synchronous nonverbal affiliation cues (SNAC), and behavioral indicators of positivity resonance (BIPR). To evaluate construct validity, we conducted a confirmatory factor analysis to test a latent factor of positivity resonance encompassing coexperienced positive affect, coexpressed positive affect, physiological linkage of interbeat heart intervals, SNAC, and BIPR. The model showed excellent fit. To evaluate associations with health and longevity, we used dyadic latent growth curve modeling and Cox proportional hazards modeling, respectively, and found that greater latent positivity resonance predicted less steep declines in health and increased longevity. Associations were robust when accounting for initial health symptoms, sociodemographic characteristics, health-related behaviors, and individually experienced positive affect. We repeated health and longevity analyses, replacing latent positivity resonance with BIPR, and found consistent results. Findings validate positivity resonance as a multimodal construct, support the utility of the BIPR measure, and provide initial evidence for the characterization of positivity resonance as a positive health behavior.

长期已婚夫妇的积极共振：多模式特征及其对健康和长寿的影响。

共同经历的积极情感的积极共振理论描述了以共享积极情感、关怀非语言同步和生物同步为特征的人际联系时刻。积极共振的结构有效性及其与健康的纵向关联尚未经过测试。目前的纵向研究检验了 154 对已婚夫妇之间冲突互动中的积极共振是否可以预测 13 年以上的健康轨迹和 30 年以上的寿命。我们利用夫妻在互动过程中对情感的连续评级来捕捉共同经历的积极情感和持续的生理反应来捕捉配偶之间的生物同步性。视频记录针对共同表达的积极情感、同步非语言关联线索（SNAC）和积极共振行为指标（BIPR）进行行为编码。为了评估构建有效性，我们进行了验证性因素分析，以测试积极共振的潜在因素，包括共同经历的积极情感、共同表达的积极情感、心跳间隔的生理联系、SNAC 和 BIPR。该模型显示出极佳的贴合度。为了评估与健康和长寿的关联，我们分别使用二元潜在生长曲线模型和 Cox 比例风险模型，发现潜在正性共振越大，健康状况下降幅度越小，寿命越长。当考虑到最初的健康症状、社会人口特征、健康相关行为和个人经历的积极影响时，关联性很强。我们重复了健康和长寿分析，用 BIPR 取代潜在的正共振，并发现了一致的结果。研究结果验证了积极共振作为一种多模式结构，支持 BIPR 测量的实用性，并为将积极共振表征为积极的健康行为提供了初步证据。（PsycInfo 数据库记录 (c) 2022 APA，保留所有权利）。
