Private self-consciousness moderating 18 month physical activity. Note: Results above are predicted values based on a multiple regression model that included Arm (t = 0.72, df = 147, p = 0.47), private self-consciousness (t = -1.02, df = 147, p = 0.31), residualized change score of physical activity from baseline to 12 months (t = 6.25, df = 147, p < 0.0001), and arm X private self-conscious (t = 2.04, df = 147, p < 0.05) predicting moderate- to vigorous-intensity physical activity (Mod+) at 18 months. Using standard conventions for modeling interaction effects, the y-axis represents the predicted value at 18 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 private self-consciousness between the automated advisor and human advisor groups. Low PSC = one Standard deviation below mean for private self-consciousness; High PSC = One standard deviation above the mean for private self-consciousness. This is based on previous conventions for graphing moderation analyses as described above.
