Narcissism has been studied for its role in leadership using various versions of the Narcissistic Personality Inventory (NPI). Narcissism is described as having a "dark and negative" side as well as a "positive or bright" side. The bright side of narcissism, in particular, has been studied for its role in leadership. In studies among military personnel in Finland and Hungary, the NPI has been associated with positive leadership traits. We assessed if measures of narcissistic personality were predictive of entrance to and graduation from the Army Ranger Course among United States (U.S.) Army personnel.
We included the NPI as one of the measures in the Ranger Resilience and Improved Performance on Phospholipid-bound Omega-3's (RRIPP-3) study. RRIPP-3 was a double-blind, placebo-controlled dietary supplement intervention trial at Fort Benning, GA, that enrolled 555 officers when they entered the U.S. Army Infantry Basic Officer Leadership Course (IBOLC) with the intention to complete the U.S. Ranger School. RRIPP-3 volunteer participants consumed eight dietary supplements daily containing 2.3 g of omega-3 (krill oil) or macadamia nut oil (control) over a 20-week period. Blood spot samples were collected to monitor intake compliance. Cognitive functioning, resilience, and mood were assessed at approximately 14 and 16 weeks. Dietary intake was also assessed. The 40-item, forced-choice NPI was included to assess if three factors of narcissism: Leadership/Authority, Grandiose/Exhibitionism, and Entitlement/Exploitativeness measures of narcissistic personality were associated with entrance to and graduation from the Army Ranger Course.
Of the 555 soldiers enrolled in RRIPP-3, there were no statistically significant differences in the total NPI scores comparing U.S. Army IBOLC officers who enrolled (n = 225) versus did not enroll (n = 330, p = .649) or graduated (n = 95; versus did not graduate [n = 460, p = .451]) from the Ranger Course. None of the three-factor NPI subscales differed statistically comparing either enrollment in (p = .442, .510, and .589, respectively) or graduation from the Ranger Course (p = .814, .508, and .813, respectively).
Although narcissism has been positively associated with military trainee success in other countries, we did not find an association between narcissism and trainee success among U.S. Army trainees, and accordingly the level of narcissism did not predict trainee success or failure.
自恋在领导力方面的作用已通过各种版本的自恋人格量表 (NPI) 进行了研究。自恋被描述为具有“黑暗和消极”的一面,也具有“积极或光明”的一面。自恋的光明面,特别是在领导力方面的作用,已经得到了研究。在芬兰和匈牙利的军事人员研究中,NPI 与积极的领导特质相关联。我们评估了自恋人格的衡量标准是否可以预测美国陆军人员进入和毕业于陆军游骑兵课程。
我们将 NPI 作为 Ranger Resilience and Improved Performance on Phospholipid-bound Omega-3's (RRIPP-3) 研究中的一项措施。RRIPP-3 是在佐治亚州本宁堡进行的一项双盲、安慰剂对照饮食补充剂干预试验,共有 555 名军官参加,他们在进入美国陆军步兵基础军官领导课程 (IBOLC) 时打算完成美国游骑兵学校。RRIPP-3 志愿者参与者每天服用八种含有 2.3 克 ω-3(磷虾油)或澳洲坚果油(对照)的饮食补充剂,持续 20 周。采集血斑样本以监测摄入情况。大约在 14 和 16 周时评估认知功能、适应力和情绪。还评估了饮食摄入情况。包括 40 个项目的强制选择 NPI 在内,以评估自恋的三个因素:领导力/权威、夸大/表现主义和权利/剥削衡量自恋人格是否与进入和毕业于陆军游骑兵课程有关。
在参加 RRIPP-3 的 555 名士兵中,比较进入(n=225)和未进入(n=330,p=.649)或毕业(n=95)的美国陆军 IBOLC 军官的总 NPI 评分,未发现统计学差异陆军游骑兵课程。在比较任何一个因素时,NPI 的三个因子亚量表在统计学上均无差异(分别为:入学[p=.442、.510 和.589]和毕业于游骑兵课程[p=.814、.508 和.813])。
尽管自恋与其他国家的军事学员的成功呈正相关,但我们没有发现自恋与美国陆军学员的成功之间存在关联,因此自恋程度并没有预测学员的成功或失败。
