Measures of external life stress, trait anxiety, self-concept, subjective stress and three measures of imagery were taken on 188 college students and were used to predict seriousness of illness in an attempt (1) to determine if cognitive mediating variables could significantly add to external life stress in the prediction of seriousness of illness, and (2) to determine if imagery, alone or interacted with self-concept, could add to the prediction. Using multiple linear regression, trait anxiety, a subjective feeling of stress, self-concept, visual imagery, sex, and an interaction between self-concept and emotive imagery significantly increased the variance when added to external life stress in predicting seriousness of illness. Trait anxiety, when added to external life stress, increased the variance by an amount greater than life stress alone. This adds support to the concept that the interpretations of stress, the cognitive mediating variables, are certainly important and in fact may be more important than environmental factors alone in predicting seriousness of illness.
对188名大学生进行了外部生活压力、特质焦虑、自我概念、主观压力以及三种意象测量，并用于预测疾病严重程度，旨在(1)确定认知中介变量在预测疾病严重程度时是否能显著补充外部生活压力，以及(2)确定意象单独或与自我概念相互作用时是否能补充预测。使用多元线性回归，特质焦虑、主观压力感、自我概念、视觉意象、性别以及自我概念与情感意象之间的相互作用在加入外部生活压力以预测疾病严重程度时显著增加了方差。特质焦虑加入外部生活压力时，增加的方差量大于单独的生活压力。这进一步支持了这样的观点，即压力的解释，即认知中介变量，肯定很重要，实际上在预测疾病严重程度方面可能比单独的环境因素更重要。
