Robustness of key predictor effects to responsibility perception operationalisation (Wave-2023).

Cell values show the number of structural measures (out of 6) for which each predictor was significant (). Consistency across columns indicates robustness to the harmonisation method. Default = 5-category ordinal (50% threshold); Binary = government-dominant vs. individual-dominant; Continuous = raw government share (0–100%); Excluded = responsibility omitted from model. Self-efficacy and flood worry show consistent significance across all operationalisations, confirming that core PMT findings are robust to the responsibility harmonisation approach. (XLSX)
