Note. All residualized scales have Mean = 0 after polynomial detrending or, to facilitate comparisons, were set to 0 if not detrended. Subsequently reported descriptives (Minimum, etc.) are on these scores. Detrending = the polynomial order of the best fitting model (e.g., 2nd = Week²). Mean* = Mean for each item prior to detrending.
