Abstract：
BACKGROUND: Amazon\'s Mechanical Turk (MTurk) appears to be a reliable resource for studying clinical populations and accessing hard-to-reach populations. Recent research suggests that MTurk may also be a viable option for military recruitment.
OBJECTIVE: The goal of the current study was to examine the utility of collecting clinical data on military samples recruited via MTurk.
METHODS: Participants were 535 military veterans (Mage = 37.45; 71.8% men; 69.5% White) who completed measures assessing trauma and mental health.
RESULTS: Findings indicate that rates of military traumas and mental health diagnoses were higher than published comparisons; posttraumatic stress disorder (PTSD) and depression symptoms were found to be higher than values found in a nationally representative sample, lower than a treatment-seeking sample, and comparable to a MTurk-recruited military sample. Alcohol misuse was found to be higher than both nationally representative and treatment-seeking samples. Psychometric analyses indicated support for convergent validity of measures, and confirmatory factor analysis results demonstrated that empirically supported factor models of PTSD were replicated in the current sample; the hybrid model demonstrated the best fit.
CONCLUSIONS: Our findings support the utility of MTurk for collecting clinical data on military samples. Increasing access to and recruitment of military samples is important for advancing the field of military psychology. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

摘要：
背景：亚马逊的机械土耳其人（MTurk）似乎是研究临床人群和访问难以到达人群的可靠资源。最近的研究表明，MTurk也可能是军事招募的可行选择。
目的：本研究的目的是检查收集通过MTurk招募的军事样本的临床数据的实用性。
方法：参与者是535名退伍军人（Mage=37.45；71.8％的男性；69.5％的白人），他们完成了评估创伤和心理健康的措施。
结果：研究结果表明，军事创伤和心理健康诊断的比率高于已发表的比较；发现创伤后应激障碍（PTSD）和抑郁症状高于全国代表性样本中的值。低于寻求治疗的样本，与MTurk招募的军事样本相当。发现酒精滥用高于全国代表性和寻求治疗的样本。心理测量分析表明支持措施的收敛有效性，和验证性因素分析结果表明，在当前样本中复制了PTSD的经验支持因素模型；混合模型显示出最佳拟合。
结论：我们的发现支持MTurk用于收集军事样本的临床数据。增加军事样本的获取和招募对于推进军事心理学领域至关重要。(PsycInfo数据库记录(c)2022年APA，保留所有权利)。
