Trust in the Indonesian Healthier Choice Logo and reported logo use among university students

This record accompanies the study “Trust in the Indonesian Healthier Choice Logo and reported logo use among university students” and is intended to support transparency and interpretation of the research. The study used a cross-sectional online survey administered in Indonesian from July 5 to July 14, 2026. The analytical sample comprised 253 university students who provided electronic consent, reported purchasing a product bearing the Healthier Choice Logo within the preceding six months, and completed the modeled questionnaire items. The core analysis examined health consciousness, logo awareness, subjective logo knowledge, perceived credibility, and trust beliefs. An exploratory extension examined self-reported logo use. Analyses included partial least squares path modeling, comparison of alternative structural specifications, bootstrap inference, measurement assessment, response-quality sensitivity analyses, subgroup comparisons, and internal predictive assessment. The findings concern associations within a selected student sample. They do not establish causal relationships, changes in actual purchasing, or improvements in dietary quality.
