Statistical, Practical, Clinical, and Personal Significance: Definitions and Applications in Speech-Language Pathology

Conclusions: Practical significance, an adjunct to statistical significance, refers to the magnitude of a change or a difference between groups. The appropriate existing term for the interpretation of treatment outcomes, or the attribution of meaning or value to treatment outcomes, is clinical significance. To further distinguish between important constructs, the authors suggest incorporating as definitive the existing notion that clinical significance may refer to measures selected or interpreted by professionals or with respect to groups of clients. The term personal significance is introduced to refer to goals, variables, measures, and changes that are of demonstrated value to individual clients.
