Exploring Couples’ Dynamics Through Time: An Approach of Dyadic-Longitudinal Qualitative Analysis

Few studies adopt dyadic and longitudinal approaches to explore couple dynamics and, to our knowledge, no qualitative research has integrated both methods. We propose and discuss a novel approach for analyzing and interpreting dyadic-longitudinal data derived from interviews conducted separately with both members of the couple across multiple time points. We propose a seven-stage procedure that integrates dyadic and longitudinal analyses through an iterative and reflexive process that moves across individual, dyadic, and longitudinal levels. Drawing on Eisikovits and Koren’s (2010) approach, we examine overlaps and contrasts in partners’ perspectives, allowing for a comparison of both individual and shared viewpoints. We also apply Saldaña’s (2003) longitudinal analysis approach, utilizing framing, descriptive, and interpretive questions to track changes over time. Yosha’s (2011) contribution of writing dyadic summaries is integrated across the analysis, moving from individual to longitudinal layers. The coding process follows Braun and Clarke’s (2022) reflexive thematic analysis, which emphasizes reflexivity and the dynamic, interpretative nature of analysis - well-suited to the complexities of dyadic-longitudinal research. Importantly, the entire analysis is interpretative, as engaging with the data aims to represent psychological processes. We illustrate our proposal using data from our study about couples’ transition to parenthood. Although resource-consuming, this approach offers a comprehensive understanding of couple dynamics by capturing both partners’ perspectives and tracing their interactions across time, providing nuanced insights into family relationships, particularly during significant life transitions.
