To measure test-retest reliability, 38 Veterans Administration clinic patients completed a modification of the Sarason Life Experience Survey (LES) twice within several weeks. Summary scores were found to be more reliable than scores on individual questions. Patients attending the Mental Hygiene Clinic responded less reliably than other patients. The "stress ladder"--a simple summary score measure--was found to be the most reliable measure of all.
为了测量重测信度,38名退伍军人管理局诊所的患者在几周内两次完成了对萨拉森生活经历调查问卷(LES)的修改版。研究发现,汇总分数比单个问题的得分更可靠。在精神卫生诊所就诊的患者的回答可靠性低于其他患者。“压力阶梯”——一种简单的汇总分数测量方法——被发现是所有测量方法中最可靠的。
