The role of gratitude and moral elevation in moral identity development

Experiencing the moral emotions of gratitude and moral elevation are responses to witnessing virtuous deeds of others. Both emotions have been found to share similar features and behavioral consequences, including the stimulation of personal development. The broaden-and-build theory of positive emotions indicates that gratitude and elevation prompt the long-term development of lasting resources. Moral identity has been found to be a personal resource in the moral domain since it is associated with higher levels of moral functioning. Therefore, using a two-wave cross-lagged panel design, the current study investigated the causal role of trait gratitude and trait elevation as antecedents of short-term moral identity development. At two points of time (time interval 17 months), a heterogeneous sample of n = 129 adults with a broad range of age completed measures of trait gratitude, trait moral elevation (engagement with moral beauty), and moral identity (internalization and symbolization of the Aquino–Reed framework). In line with our hypotheses, trait moral elevation predicted increases in moral identity internalization. In contrast to our hypotheses, the development of trait gratitude was predicted by moral identity internalization, and not the other way around. Exploratory analyses showed that no cross-lagged effects could be found for the symbolization dimension. In addition, a multi-group analysis explored which of the cross-lagged effects could be generalized across age groups. The results are discussed in the context of the moral emotion research.
