Cohesion and peer trust during embedded team reflection in elite underwater rugby: Analysis code and aggregate supporting materials

This archive accompanies the manuscript “Cohesion and peer trust during embedded team reflection in elite underwater rugby: A three-wave field study”. The study followed cohesion-related perceptions and peer trust across three assessments during a structured team-reflection period in an elite men’s underwater rugby squad. Twenty-five athletes contributed 63 assessments (baseline: 18; midpoint: 23; endpoint: 22); 16 completed all three waves.The archive contains the analysis code, aggregate descriptive statistics and mixed-model results, complete-case sensitivity estimates, supplementary documentation, the reconstructed reflection topic guide, scoring information, reported internal-consistency coefficients, and the source data and code for the study figure. A verification script checks agreement among the aggregate files and the figure calculations.The figure can be regenerated directly from the public aggregate outputs. Re-estimating participant-level models and internal-consistency coefficients requires the controlled source workbook. Participant-level responses and linkage keys are not included. Qualified researchers may request access through the corresponding author, subject to confidentiality safeguards, applicable ethical and institutional requirements, and a data-use agreement.This deposit contains code and supporting materials, not the manuscript or participant-level dataset.
