ABSTRACT
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 (ß = -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.
