N = 300 (Cohorts 1–3 combined). Hornik & Woolf (1999) percentage-to-gain analysis. Outcome dichotomy: “Definitely will” (top of 7-point scale). Predictor dichotomy: top response category if positively correlated with the intent composite; bottom if negatively correlated. Ceiling flag (⊙): ≥ 60% already at desired position. Small-n flag (▲ / ⚠): fewer than 30 participants at the desired position — PTG estimates for these items are unreliable and should not drive prioritization decisions. Moveable beliefs only (demographics excluded).
Included for reference. These items reflect prior behavior rather than modifiable beliefs.
