From: Exploratory study of the impact of perceived reward on habit formation

Outcome Time 0 Mean (SD) Time 1 Mean (SD) Time 2 Mean (SD) Time 3 Mean (SD) Time 4 Mean (SD) t test
Flossing behaviour 0.85 (1.01) 1.69 (1.91) 4.55 (2.42) 4.39 (2.41) 4.10 (2.58) 8.29***
Flossing automaticity 1.54 (1.55) 2.11 (1.73) 3.54 (1.81) 3.67 (1.96) 3.75 (2.07) 7.82***
Vitamin C behaviour 1.35 (2.60) 4.61 (2.59) 4.06 (2.80) 4.01 (2.88) 3.89 (2.14) 5.53***
Vitamin C automaticity 2.11 (1.25) 3.76 (1.90) 3.64 (2.10) 3.44 (2.13) 3.53 (2.31) 5.30***
  1. Note: The behaviour values are recorded as weekly behaviour frequency
  2. The t test results refer to the comparison between behaviour/automaticity levels at the point of the intervention and the end of the study. T0 values for vitamin C reflect pre-intervention levels, and T1 values for flossing reflect pre-intervention levels
