The Case Against the Design Hierarchy in Psychological Network Analysis
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.
