The authors evaluated the convergent validity of several widely used psychometric tests of posttraumatic stress disorder (PTSD) symptoms against DSM-III-R criteria for PTSD in 130 Vietnam combat veterans. Significant positive correlations were found between these instruments and the number of DSM-III-R symptoms endorsed, supporting the validity of psychometric instruments as continuous measures of PTSD symptom severity. The various psychometric measures also correlated moderately with one another, suggesting that they assess related but somewhat separate PTSD phenomena. Finally, predicted relationships between stressors and symptoms were supported by significant correlations between degree of traumatic combat exposure and DSM-III-R and psychometric indexes of PTSD.
作者针对130名越战退伍军人，根据精神障碍诊断与统计手册第三版修订本（DSM-III-R）中创伤后应激障碍（PTSD）的标准，评估了几种广泛使用的PTSD症状心理测量测试的收敛效度。这些工具与认可的DSM-III-R症状数量之间发现了显著的正相关，支持了心理测量工具作为PTSD症状严重程度连续测量指标的有效性。各种心理测量指标之间也存在适度的相关性，表明它们评估的是相关但又有所不同的PTSD现象。最后，创伤战斗暴露程度与DSM-III-R以及PTSD心理测量指标之间的显著相关性支持了应激源与症状之间的预测关系。
