The evaluative research as a bridge between science and profession

The evaluative research is an important goal of applied research in psychology, and can constitute a link between scientific research and the definition of an evidence-based profession, in many fields of psychology: e.g., educational, social, work, clinical psychology. But to make a good evaluative research some methodological considerations are needed. First of all, the complexity of this field of study overwhelms the traditional methods based on laboratory research, which defines and manages variables, sampling, and statistical analyses in a reductive way.
