Loneliness is associated with adverse outcomes, and the COVID-19 pandemic threatened to increase loneliness. How loneliness-related outcomes unfold, though, varies across individuals. Individuals' sense of social connectedness and engagement with others to regulate emotional experiences (interpersonal emotion regulation; IER) may modulate loneliness-related outcomes. Individuals failing to maintain social connectedness and/or regulate emotions may be at heightened risk. We assessed how loneliness, social connectedness, and IER related to valence bias, a tendency to categorize ambiguity as more positive or negative. Loneliness was associated with a more negative valence bias among individuals reporting above average social connectedness but who shared positive emotion less often (z=-3.19, p=.001). These findings suggest that sharing positive emotional experiences may buffer loneliness-related outcomes during shared adverse experiences.
