This study used secondary analysis of data from two studies of expressive writing about stressful relational events to first describe the relations of word use to social-cognitive maturity of role-taking using Feffer’s Interpersonal Decentering scoring system and then to test hypotheses about active processing of relational information versus event closure. This scoring system for imaginative Thematic Apperception Test stories was adapted for expressive writing protocols and related to proportions of cognitive and emotional words used, relationship characteristics, and the subjective experience of writing. Relational events included relationship breakups (including divorce), loved one’s illness or death, and abuse. Decentering maturity was positively correlated with cognitive and insight words and with positive emotion words in both studies’ narratives, and also with self-rated experiences of emotional intensity in the low closure group only. Gender differences were consistent with gender theories applied to relational stressors.
