TABLE A1.

Changes in the raw score of sense of control from the pre‐baseline wave (t₀) to the outcome wave (t₂)^*

	Pre‐baseline wave (t0)	Outcome wave (t2)
	Mean (SD)	Mean (SD)
Sense of control	4.76 (0.97)	4.77 (0.98)

^*The correlation coefficient for sense of control between waves t₀ and t₁ was 0.41. Further, the correlation coefficient for sense of control between waves t₁ and t₂ was 0.32. The numbers in the table are raw scores, and not standardized scores. Further, the actual mean change in sense of control from the Pre‐Baseline Wave (t0) to the Outcome Wave (t2) was −0.0107.
