The study focuses on the frequency of inpatient care for patients with Posttraumatic Stress Disorder (PTSD). This factor, termed "chronicity," is, perhaps surprisingly, largely overlooked in many PTSD studies. The significance of chronicity was addressed through administration of Minnesota Multiphasic Personality Inventory (MMPI) to Vietnam Theater and Era veterans in an inpatient psychiatry service. MMPI scores were analyzed for two main effects: combat exposure and chronicity (i.e., number of inpatient psychiatry admissions). The results replicated research showing combat exposure is associated with greater maladjustment (i.e., higher MMPI scores). Moreover, chronicity also emerged as a significantly important variable: of all groups compared, Vietnam combat veterans higher in chronicity scored higher on MMPI clinical scales, particularly on scales Paranoia, Psychasthenia, and Schizophrenia, thereby (a) empirically establishing (a) the methodological point that number of admissions must be controlled and (b) the substantive point that chronicity is important in studies of PTSD.
该研究聚焦于创伤后应激障碍（PTSD）患者的住院治疗频率。这个被称为“慢性病程”的因素，或许令人惊讶的是，在许多PTSD研究中很大程度上被忽视了。通过对在住院精神科接受治疗的越南战争时期及战后退伍军人进行明尼苏达多相人格调查表（MMPI）测试，探讨了慢性病程的重要性。对MMPI分数分析了两个主要影响因素：战斗经历暴露程度和慢性病程（即住院精神科治疗的次数）。研究结果重复了此前的研究，即战斗经历暴露与更严重的适应不良（即更高的MMPI分数）相关。此外，慢性病程也成为一个显著重要的变量：在所有比较的组中，慢性病程程度较高的越南参战退伍军人在MMPI临床量表上得分更高，尤其是在偏执狂、精神衰弱和精神分裂症量表上，从而（a）从经验上确立了（a）必须控制住院次数这一方法学要点，以及（b）慢性病程在PTSD研究中很重要这一实质性要点。
