Evaluation

There are several reasons to include an evaluation at the end of a prevention programme First, curiosity of those involved in the programme as to how successful their programme has been. Second, funding resources usually require some form of assessment in order to determine whether their money has been wisely invested. Third, and perhaps most important, an objective evaluation is the only credible method available to determine the effectiveness of preventive activities and programmes.

There are two kinds of evaluation: process evaluation and effect - or outcome evaluation. The central question in process evaluation is: did we accomplish our goals? Why or why not? Has the prevention programme been carried out in the way we intended and planned? Have resources been utilized as initially planned? Have we used the funds appropriately? Was the target group satisfied with the way the prevention programme was carried out? What has been the opinion of the community (local council, key-persons, the media, etc).

The second kind of evaluation deals with the effects of the prevention programme. Whilst, it is not always possible to determine or measure the intended effects or outcomes of prevention efforts, attempts should be made to discover if there is any evidence of reduction of drug use or drug problems in the community, or whether the community is more aware or better informed about drug use and drug problems.
