Recalled protective childhood experiences are associated with positive emotional expression in active-duty...

There is a wealth of research linking adverse childhood experiences (ACEs) with negative outcomes later in life, but less research has focused on the effects of protective childhood experiences (PCEs). PCEs have been shown broadly to promote resilience, but the precise nature of this association is not clear, particularly in studies of at-risk adults. The current investigation explored the association between recollection of early life experiences and in vivo emotional responses in at-risk adults. In 2018, 56 active-duty firefighters reported childhood experiences via a questionnaire. Using a semistructured interview, firefighters then responded to questions about recent emotionally evocative experiences (positive and negative) as a firefighter. Emotion was measured in vivo via sympathetic arousal and recorded facial expressions of emotion. Individuals who reported more PCEs expressed significantly more facial expressions of positive emotion across contexts, sr² = .11-.14. Early childhood experiences were not significantly associated with negative facial expressions or changes in sympathetic reactivity, but ACEs were associated with tonic levels of arousal in a negative context, r = -.36. Given the adaptive role of positive emotions in adjustment to adverse events, the current investigation suggests a potential protective association between PCEs and the expression of emotion even within a high-risk context, which could help explain the resilience promoting role of PCEs.
