Emotional functioning can be assessed across multiple levels of analysis (e.g., subjective, physiological). The degree of concordance/discordance across such indices may mark psychopathology risk. The current study assessed associations between physiological and subjective indices of emotional responding among drinkers, with (n = 39) and without (n = 42) borderline personality disorder. Subjective changes in affect were assessed by calculating difference scores on the Positive and Negative Affective Schedule, administered before and following a lab-based stress task. Physiological dysregulation was indexed by respiratory sinus arrhythmia (RSA) reactivity. We created Discordance Index scores to examine the direction and magnitude of misalignment. More frequent alcohol use was associated with greater discordance between RSA and positive affect changes (β = −0.07, p-value = 0.009). Findings were confirmed with a response surface modeling analysis. Results highlight that individuals with greater discordance between indices of emotional responding may be at elevated risk for frequent alcohol use.

可以在多个分析水平（例如，主观，生理）上评估情绪功能。跨这些指数的一致/不一致的程度可能标志着心理病理风险。本研究评估了（n = 39）和没有（n = 39）饮酒者的情绪反应的生理和主观指标之间的关联= 42）边缘人格障碍。通过在基于实验室的压力任务之前和之后进行的“正面和负面情感安排”上计算差异评分，评估情感的主观变化。生理异常由呼吸窦性心律不齐（RSA）反应性来指示。我们创建了不一致指数分数来检查未对准的方向和程度。频繁饮酒与RSA和正面情感变化之间的更大不一致（β= -0.07，p值= 0.009）相关。通过响应面建模分析确认了发现。结果表明，情绪反应指数之间差异较大的人经常饮酒的风险较高。
