Toward understanding and measuring adaptation level in the context of the Roy adaptation model

The Roy adaptation model concepts of stimuli, coping mechanisms, and modes of adaptation have been translated into several middle-range concepts and measured using existing and new instruments. The concept of adaptation level, however, has rarely been used in Roy adaptation model-based research. This paper presents a description of how the Roy adaptation model concept of adaptation level was translated into the logically congruent middle-range theory concept of adjustment. A single-item instrument, the Adjustment Scale, is identified as one way to measure adjustment.
