The Case Against the Design Hierarchy in Psychological Network Analysis
Year: 2026
Type: preprint
Abstract: The network perspective conceptualizes psychological phenomena as systems of interacting components, placing dynamics at the center of explanation. This has justified criticism of studies that use cross-sectional networks to claim within-person dynamics, uniquely identified causal mechanisms, or effective intervention targets. In the current methodological climate, however, an implicit design hierarchy has emerged in which cross-sectional design is itself treated as the objection. In an audit of 157 papers across three journals, 65% of 127 eligible papers named cross-sectional design as a limitation and 68% recommended longitudinal research as a remedy. Such a hierarchy mischaracterizes designs operating at different temporal scales: they estimate different structures rather than progressively better answers to one question. Cross-sectional networks can distinguish conditional from marginal associations, characterize the conditional-association structure, support measurement development, identify patterns for replication, and generate constrained hypotheses, particularly when measures represent characteristic tendencies or experiences over a defined period. Longitudinal and intensive longitudinal designs are not automatic upgrades over cross-sectional designs; their evidential value depends on temporal resolution, lag selection, measurement quality, model assumptions, and the distinction between group-average and person-specific inference. Designs should therefore be judged by alignment of question, measurement, model, and claims—not by position in an assumed hierarchy.
