The use of different dependent variables is the primary feature that differs a single-subject design from a program evaluation the essence of which is to cover a range of questions and evaluate them all without using specific data. According to Nielson (2015), a practice-based study backed by a single-case design is an excellent approach for solving various problems, including those that are directly related to social sciences. Perhaps, if such a method of work and analysis had not been invented, too narrowly focused studies would be conducted today, and little useful data would be collected.

An independent variable in the research project is one of the key factors on which the outcome of work depends. When working with the victims of human trafficking, special attention should be paid to psychological aspects since some deviations of the psyche under the influence of stress are possible. Therefore, it is essential that participants themselves understand the actions taken by researchers and why specific approaches are used. In this case, the target group is likely to show even greater interest, and a number of data can be supplemented with valuable information that may be necessary for successful research.
The effectiveness of the program can certainly be assessed if all the information about the organization of the project is present. The required information will include not only data on program participants but also other additional facts, for instance, timelines, resources, stakeholders, etc. If most of this information is known, it will not be difficult to determine whether a particular design is successful or not.
