The purpose of the Derdiarian Behavioral System Model (DBSM) instrument was to measure and describe, within the Johnson Behavioral System Model (JBSM) perspective, the perceived behavioral changes of the cancer patient. Based on Johnson's (1968, 1980) premise that illness as a noxious stimulus effects imbalance in the behavioral system of the human being, it was extrapolated that changes that occur in a patient's behavioral patterns would be perceived by the patient. Thus, changes would reflect the description of the imbalance in the patient's behavioral system, which needs to be identified and described in a systematic way. The description of change was envisioned in terms of (1) the perceived existence of change; (2) the direction of change--increase or decrease; (3) the quality of change--positive or negative; (4) the importance of change--its significance; and (5) the physical, psychological, or emotional effect(s) of the illness perceived as causally associated with the change.
德尔迪亚里安行为系统模型（DBSM）工具的目的是，从约翰逊行为系统模型（JBSM）的角度，测量和描述癌症患者所感知到的行为变化。基于约翰逊（1968年、1980年）提出的疾病作为一种有害刺激会影响人类行为系统失衡的前提，由此推断患者行为模式中发生的变化会被患者感知到。因此，这些变化将反映患者行为系统失衡的描述，而这种失衡需要以系统的方式进行识别和描述。对变化的描述设想为以下几个方面：（1）感知到的变化的存在；（2）变化的方向——增加或减少；（3）变化的性质——积极或消极；（4）变化的重要性——其意义；以及（5）被视为与变化有因果关系的疾病所产生的身体、心理或情感影响。
