Abstract
The study's purpose was to examine the measurement domain of confidence items used in physical activity research. We hypothesized that confidence items, including a phrase to hold motivation constant, would differ from standard confidence items. Participants ( N = 248 students) completed confidence items, a thought‐listing procedure, and a 2‐week self‐report of physical activity. Results showed that confidence items with motivation held constant loaded exclusively on one factor, but standard confidence items were factor complex with intention. Correlations with physical activity intention and behavior were larger for confidence items than confidence items with motivation held constant. Finally, the thought‐listing procedure identified that 3 of the 7 reasons for answering confidence items were outside the intended measurement domain of self‐efficacy.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
