Stress questionnaires, anxiety scales, and cortisol measurements address different outcomes. A marker change alone does not establish improved everyday perceived stress.
Baseline stress, a short-term challenge, and a clinical population provide different contexts. Keep whole-group and subgroup findings separate.
