Amotivation moderating 12 month physical activity. Note: Results above are predicted values based on a multiple regression model that included arm (t = 0.11, df = 147, p = 0.91), amotivation (t = -1.2, df = 147, p = 0.24), baseline moderate- to vigorous-intensity physical activity (Mod+) (t = -7.0, df = 147, p < 0.0001), and arm X amotivation (t = 3.31, df = 147, p = 0.0012). Using standard conventions for modeling interaction effects, the y-axis represents the predicted value at 12 months of physical activity (i.e., kilocalories burned per kilogram per day that was in the moderate to vigorous intensity range) for those high and low in amotivation between the automated advisor and human advisor groups. Low Amot = One Standard deviation below mean for amotivation; High Amot = One standard deviation above the mean for amotivation.
