The method for questionnaire construction described in this paper makes it convenient to generate as many different forms for a questionnaire as there are respondents. The method is based on using the computer to produce the questionnaire forms themselves. In this way the items or subgroups of items of the questionnaire may be randomly ordered or sampled as each form is being generated. This provides a very direct way of dealing with order and combination effects. The technique also provides a number of incidental benefits, such as direct production of forms bypassing some stages of the usual process, and the prevention of collaborative responses in a group administration situation, since each form is "different". The paper includes a description of the method and of a pair of computer programs designed to implement it, a User's Guide for each program, and program listings. (Author/BW)
