Evaluating the screening procedure used in A case, the screening procedure that the group used had a number of flaws which may have affected the efficieny of the screening process. In general, the survey is able to deliver the expected results however in a limited fashion. As stated in the case, many volunteers were not able to interpret the questions without assistance. This is mainly caused by the ambiguity of the questions. For instance in the second question the respondents are asked to state whether they see drug use as a problem.

Another problem with the questionnaire was that it was possibly not able to grab the attention of the respondents. This has two possible reasons. Firstly the introductory paragraph could have better wording. Stating the payment respondents are going to receive is an advantage, but stating the aim of the questionnaire may be a possible turn off.

For instance, respondents could have chosen from a
