Mean behaviour frequency and automaticity for flossing and vitamin C throughout the study
| 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*** |
Note: The behaviour values are recorded as weekly behaviour frequency
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
