Beliefs About Emotion Shift Dynamically Alongside Momentary Affect

This study examined if beliefs about emotion change across emotional contexts in daily life, and it investigated whether people with prominent features of borderline personality pathology experience greater shifts in emotion beliefs during emotional states. Undergraduate participants with (n = 49) and without borderline features (n = 50) completed a 1-week ecological momentary assessment study where they provided ratings of affect, nine different beliefs about emotion, and indicators of momentary self-efficacy. Results support the notion of beliefs as relatively schematic. However, most of the beliefs about emotion shifted with either positive or negative affect, and they predicted momentary self-efficacy for tolerating distress and exerting willpower. Those with borderline features experienced greater instability of beliefs, and borderline features moderated the relationships between affect and many beliefs. Results confirm that there are implications for emotion beliefs for people who struggle with emotion regulation and impulsivity (i.e., people with features of borderline personality).
