You can visit Evaluation on the navigation bar below for general information on evaluation. This section is designed to add to this general information by giving you special considerations for evaluating campaigns and promotions.

Work with members of the community of interest to develop the messages through participatory approaches or focus groups. This can assist in ensuring that the messages are conveying what is intended to be conveyed. Mass media campaigns might include an assessment of how frequently the messages were run, when they were run, and if the actual messages fit with what was intended when the messaged were developed. In addition, you could evaluate the extent to which messages were seen, whether the intended audience has heard of the campaign and how much or how many of the messages were remembered.

Community wide surveys could be used to measure these factors and to assess changes knowledge, attitudes or eating patterns. It may be helpful to combine these with observations and non-intrusive assessments (such as reviewing grocery store, restaurant, or worksite/school cafeteria sales). Alternately, it may be useful to determine whether the number of programs or attendance at programs offered in the community (e.g., low fat cooking classes) has increased as a result of the media messages. This might involve conducting interviews with representatives of the organizations who are offering these programs or tracking how individuals attending the classes learned about the program.

There are several challenges in evaluating media campaigns that should be considered:

  • With mass media campaigns, it is often difficult to establish causality (e.g., the media message caused fifty individuals to eat more fruits and vegetables). Some individuals might have changed their consumption of fruits and vegetables their own and others may have been influenced by a friend, a co-worker or another mass media campaign in their area. Therefore, it is important to get as much information as possible about the reason for the increase in consumption. Comparison with other communities may also be helpful, and assessing why individuals decided to change their eating patterns, and the association of these reasons with the specific messages conveyed in your media campaign, may be helpful.
  • The exact number of media messages necessary to create change or reach the intervention objectives is not known; and it is not really feasible to document exposure to specific messages or a total number of messages. Individuals may have difficulty remembering whether or not they have seen a message, let alone multiple messages with a similar look and feel to them.
  • When the mass media strategy is used along with other strategies (the most effective way to create change), it is difficult to figure out which intervention strategies led to the changes that were observed in the evaluation.
