Delineation of the relationship between health locus of control (HLOC) and psychological adjustment in chronic disease has been hampered by the failure to consider the moderating effect of contextual factors. The extent to which HLOC beliefs match the control realities in a situation (Reality Matching hypothesis) as well as the degree of threat (Threat hypothesis) posed by the situation were hypothesized to moderate the HLOC-distress relationship. Distress, disease severity (i.e., threat), and HLOC were assessed in 69 individuals with malignant disease undergoing evaluation for bone marrow transplantation. Hierarchical regression analyses indicated that the HLOC-distress relationship was moderated by disease severity and treatment history (i.e., whether an individual had failed prior cancer therapy). However, in some instances, the specific interaction relationships obtained differed from those evident in previous research with ESRD patients. It was concluded that there is no simple main effect relationship between HLOC beliefs and psychological adjustment. Rather, this relationship is best described by joint consideration of factors descriptive of the context in which the individual is embedded.
由于未能考虑情境因素的调节作用，健康控制点（HLOC）与慢性病心理调适之间关系的描述受到了阻碍。HLOC信念与情境中控制现实的匹配程度（现实匹配假说）以及情境所构成的威胁程度（威胁假说）被假定为调节HLOC-痛苦关系。对69名接受骨髓移植评估的恶性疾病患者进行了痛苦、疾病严重程度（即威胁）和HLOC的评估。分层回归分析表明，HLOC-痛苦关系受到疾病严重程度和治疗史（即个体先前的癌症治疗是否失败）的调节。然而，在某些情况下，所获得的具体交互关系与先前对终末期肾病患者的研究中所显示的关系有所不同。得出的结论是，HLOC信念与心理调适之间不存在简单的主效应关系。相反，这种关系最好通过共同考虑描述个体所处情境的因素来描述。
