Outcomes are the changes that result from an intervention. Outcomes could be changes in attitudes, or knowledge, or behaviour, for example. Short-term outcomes are the immediate changes that happen in the time period straight after an intervention: for example, increased knowledge. Long-term outcomes may not be achieved straight away but can still be the result of an intervention; they are a logical consequence of the short-term outcomes changed behaviour as a result of increased knowledge for instance. Intended Outcomes: Intended outcomes are the changes that the intervention was designed to achieve, for example: increased seat belt wearing following a seat belt education campaign. Unintended Outcomes: Unintended outcomes are the changes that result from an intervention but that were not planned for or expected. Unintended outcomes can be positive (desirable) or negative (undesirable). Even if they were not expected or desired, they should still be recorded and reported on
