SCORING

Dimension Items

Intrinsic, Health Concerns 1, 5, 9, 13, 17

Intrinsic, Self-Control 2, 6, 10, 14, 18

Extrinsic, Immediate Reinforcement 3, 7, 11, 15, 19

Extrinsic, Social Pressure 4, 8, 12, 16, 20

COMPUTATION

We score the scaled as average ratings across the relevant sub-dimension items. Items with missing ratings can be excluded from the denominator. For example, the health concerns score = Sum of items (1 + 5 + 9 + 13 + 17)/5

If item #9 is missing data, the calculation would be the sum of items (1 + 5 + 13 + 17)/4

Level of intrinsic relative to extrinsic motivation is calculated as a difference score with the extrinsic scale score subtracted from the intrinsic score.
