In order to investigate the long-term psychological consequences of Viet Nam combat, the authors located and personally interviewed a group of 571 randomly selected Viet Nam veterans and 284 matched civilian controls 3 years after the veterans returned to the United States. In the veterans they found a weak association between combat and subsequent depressive symptoms, but the association did not persist after controlling for preservice factors. The incidence of depressive symptoms and syndromes was similar when veterans were compared with nonveterans. Results are contrasted with a 12-month follow-up study of the same veterans in which a stronger association between combat and later depression was found.
为了调查越南战争的长期心理影响，作者在退伍军人回到美国三年后，找到了571名随机挑选的越南退伍军人，并对其进行了个人访谈，同时还采访了284名匹配的平民对照者。他们发现退伍军人中，参战经历与随后出现的抑郁症状之间存在微弱关联，但在控制入伍前因素后，这种关联不再持续。将退伍军人与非退伍军人相比，抑郁症状和综合征的发生率相似。研究结果与对同一批退伍军人进行的为期12个月的随访研究形成对比，在那次随访研究中发现参战经历与后来的抑郁症之间存在更强的关联。
