Measuring Negative Emotion Differentiation Via Coded Descriptions of Emotional Experience.

Emotion differentiation (ED) has been defined in terms of two abilities: (a) making fine-grained distinctions emotional experiences, and (b) describing emotional experiences with a high degree of nuance and specificity. Research to date has almost exclusively focused on the former, with little attention paid to the latter. The current study sought to address this discrepant focus by testing two novel measures of negative ED (i.e., based on negatively valenced emotions only) via coded open-ended descriptions of individual emotional experiences, both past and present. As part of a larger study, 307 participants completed written descriptions of two negative emotional experiences, as well as a measure of emotion regulation difficulties and indices of psychopathological symptom severity. Negative ED ability, as measured via consistency between emotional experiences, was found to be unrelated to negative ED ability exhibited via coding of language within experiences. Within-experience negative ED may offer an incrementally adaptive function to that of ED between emotional experiences. Implications for ED theory are discussed.
