Narrative and emotion process in psychotherapy: An empirical test of the Narrative-Emotion Process Coding System (NEPCS)

Abstract

Objective: While the individual contributions of narrative and emotion processes to psychotherapy outcome have been the focus of recent interest in psychotherapy research literature, the empirical analysis of narrative and emotion integration has rarely been addressed. The Narrative-Emotion Processes Coding System (NEPCS) was developed to provide researchers with a systematic method for identifying specific narrative and emotion process markers, for application to therapy session videos. Method: The present study examined the relationship between NEPCS-derived problem markers (same old storytelling, empty storytelling, unstoried emotion, abstract storytelling) and change markers (competing plotlines storytelling, inchoate storytelling, unexpected outcome storytelling, and discovery storytelling), and treatment outcome (recovered versus unchanged at therapy termination) and stage of therapy (early, middle, late) in brief emotion-focused (EFT), client-centred (CCT), and cognitive (CT) therapies for depression. Results: Hierarchical linear modelling analyses demonstrated a significant Outcome effect for inchoate storytelling (p = .037) and discovery storytelling (p = .002), a Stage × Outcome effect for abstract storytelling (p = .05), and a Stage × Outcome × Treatment effect for competing plotlines storytelling (p = .001). There was also a significant Stage × Outcome effect for NEPCS problem markers (p = .007) and change markers (p = .03). Conclusion: The results provide preliminary support for the importance of assessing the contribution of narrative-emotion processes to efficacious treatment outcomes in EFT, CCT, and CT treatments of depression.
