There is no such thing as a research methodology special to industrial therapy. But, industrial therapy has its own special subject matter, suitable for development of its own scientific systematizations. Industrial therapists, as a group, are capable of distinguished scientific research. They have failed to engage actively in research because of lack of a research tradition and because of fear that their deficient research training makes them liable to blunder. However, without active research, industrial therapists cannot best perform their clinical functions. Industrial therapy is likely to wither away as a separate specialty unless it is nourished by a body of research data of its own.
