83 female patients with breast tumors were interviewed prior to biopsy. The interview contained a psychological instrument measuring action control as an indicator for the patients' reaction to stress together with questions about the expected diagnosis. Using multiple-regression analysis we estimated the explained variance of the variables relating to the histological result of the biopsy. Since most of the patients gave a correct prognosis of the nature of their disease-this variable proved to be very important-most of the social psychological findings have to be interpreted as consequences rather than causes of cancer.
83名患有乳腺肿瘤的女性患者在活检前接受了访谈。访谈包含一项测量行动控制的心理工具，以此作为患者对压力反应的指标，同时还包括有关预期诊断的问题。我们使用多元回归分析来估计与活检组织学结果相关变量的解释方差。由于大多数患者对自身疾病的性质做出了正确的预后判断——这一变量被证明非常重要——因此大多数社会心理学研究结果必须被解释为癌症的后果而非原因。
