Sometimes considered to be open questions due to their complexity cannot be put at the end of the questionnaire. The truth in this. But at this point there are other considerations. The Respondent who met with the content of the questionnaire is easier to navigate in the context of the answers to the open question, which, as a rule, is formulated in the framework of the subject. Despite the fact that the end of the questionnaire is not the best place for answers to them, however, it has to go in order to clearly Orient the respondents which aspect to respond to a particular open question, though, of course, and in this case it still is (aspect) is quite wide.There is another consideration. The fact that the open questions posed at the end of the questionnaire, it is easier handled from a purely technical point of view. Given the complexity of coding work, especially if you have to process large amounts of questionnaires, for example, several thousand questionnaires, the technical side processing is important. It's one thing when the encoder moves all pages of the questionnaire and chooses the answers to the open questions scattered throughout the questionnaire in different places, and quite another thing when they all gathered in one place at the end of the questionnaire. Open the last page and all the answers to the open questions, is evident. Selective timing of the operation of the encoders showed that in the second case, the complexity is reduced in two or three times, and the total processing time of open questions is reduced to 30%. And, most important, in this case, the encoders allow for less gaps in the respondents ' answers to the open question, fewer mistakes when writing out responses and their encoding. Thus, in one study, open-ended questions were located in the middle of the questionnaire. This was done for logical completion of a series of questions focused on the study of the phenomenon. In this case, the number of passes of the encoding of the answers of the respondents were 2-3 times higher than in the second study, when the same open-ended question located at the end of the questionnaire. Gaps in coding the answers are always. Thus, the coding of the occupations of respondents not the number of responses, i.e., their pass encoders, is from 3 to 7%.Of course, the location of open questions at the end of the questionnaire has its drawbacks, which have already been mentioned, but of two evils to choose the least. For small arrays of open-ended questions can be placed in the middle of the questionnaire if there is a particular need for large - better to put them at the end of the questionnaire if it is not due to the strict methodological requirements of informative nature.
