TY - CHAP M1 - Book, Section TI - What Does a Change in the Outcome Measurement Indicate? A1 - Riddle, Daniel L. A1 - Stratford, Paul W. PY - 2013 T2 - Is This Change Real? AB - Have you ever reassessed a patient by repeating measurements and wondered whether the change (either improvement or worsening) that may have occurred indicated real and important change or whether it was simply measurement error? More than likely, the smaller this change, the more you questioned whether it was real or important. Well, if you answered yes to the question, we are not surprised. Judging change is one of the most common dilemmas faced by physical therapists with practically every patient at some point during the plan of care. In Chapter 1 we stated, “The conscientious and judicious assessment of patients' outcomes is a complex clinical skill, much like patient assessment and treatment selection and delivery, and requires a conceptual framework and a specific body of knowledge.” Perhaps nowhere is the complexity of outcome assessment more evident than in understanding the interpretation of change scores. Key to this issue is the interpretation of threshold values of change supplied in different research papers and secondarily in many textbooks. SN - PB - F. A.
