Spill over score = score assigned to the target behaviour based on its potential to impact on behaviour change and its likelihood of changing behaviour; Measurement score = Final score assigned to the target behaviour; Very promising = highly likely to change behaviour; Promising = likely to change behaviour; Unpromising, but worth considering = may not change behaviour within the given context but can be considered
