The Vicissitudes of Conflict Measurement
Stability and Reliability in the Frequency of Disagreements
1This paper is part of a series on “Youth Development in Europe: Transitions and Identities” that will appear in the European Psychologist throughout 2008 and 2009. Taken together, the papers aim to make a conceptual contribution to the increasingly important area of youth development, especially within the context of an expanding Europe, by focusing on variations and changes in the transition to adulthood and emerging identities. The series will conclude with a summary by the organizers of the series, Katariina Salmela-Aro (University of Jyväskylä, Finland) and Ingrid Schoon (University of London, UK).
Abstract
This report examined the stability and reliability of self-reported conflict frequency in relationships with mothers, fathers, and best friends. Participants were drawn from three independent samples in the Netherlands (n = 72, M = 15.6 years), Germany (n = 242, M = 19.7 years), and the United States (n = 250, M = 19.8 years). Participants completed both topic-based surveys and interaction-based diary assessments of conflict frequency. Within samples, comparable levels of internal consistency and temporal stability emerged in each relationship for both assessment techniques. Topic-based and interaction-based assessments of conflict frequency were moderately correlated in each relationship within samples. Daily topic-based assessments with short intervals between time points may provide the most advantageous assessment strategy for obtaining reliable measures of conflict frequency in adolescents’ close relationships.
