“…We examined general categories of negative (i.e., anger, frustration, betrayal, and disappointment) and positive emotions (i.e., happy, proud, and grateful) that are likely to be influential for broken and fulfilled promises, respectively. Future research may benefit from further expanding the scope of the emotions (e.g., anxiety, disgust, relief, and surprise) and/or examining specific discrete emotions to provide further precision in identifying how emotional responses can propel specific behavioral reactions (e.g., Kiefer & Antoni, 2019). Consistent with the literature, we used a generalized composite measure that focused on fulfillment and collapsed multiple assessments of fulfilled promises into a single measure (see Zhao et al, 2007 for a discussion).…”
