The current study examined relationships among self-reported depression severity, posttraumatic stress disorder (PTSD) symptom severity, and grade point average (GPA) among student servicemembers and veterans. We asked 422 student servicemembers and veterans (72% male, 86% Caucasian, mean age = 36.29 yr) to complete an anonymous online survey that assessed self-reported GPA, depression severity, PTSD severity, and frequency of academic problems (late assignments, low grades, failed exams, and skipped classes). Female respondents reported a slightly higher GPA than males (3.56 vs 3.41, respectively, p = 0.01). Depression symptoms (beta weight = -0.174, p = 0.03), male sex (beta weight = 0.160, p = 0.01), and younger age (beta weight = 0.155, p = 0.01) were associated with lower GPA but not PTSD symptoms (beta weight = -0.040, p = 0.62), although the interaction of depression and PTSD symptoms showed a nonsignificant inverse relationship with GPA (beta weight = -0.378, p = 0.08). More severe depression was associated with turning in assignments late (beta weight = 0.171, p = 0.03), failed exams (beta weight = 0.188, p = 0.02), and skipped classes (beta weight = 0.254, p = 0.01). The relationship of depression with self-reported GPA was mediated by frequency of failed examns. Results suggest that student servicemembers and veterans with greater emotional distress also report worse academic performance.
本研究调查了学生军人及退伍军人自我报告的抑郁严重程度、创伤后应激障碍（PTSD）症状严重程度与平均绩点（GPA）之间的关系。我们邀请了422名学生军人及退伍军人（72%为男性，86%为白人，平均年龄 = 36.29岁）完成一项匿名在线调查，该调查评估了自我报告的GPA、抑郁严重程度、PTSD严重程度以及学业问题（作业迟交、成绩低、考试不及格和逃课）的频率。女性受访者报告的GPA略高于男性（分别为3.56和3.41，p = 0.01）。抑郁症状（β权重 = -0.174，p = 0.03）、男性（β权重 = 0.160，p = 0.01）和年龄较小（β权重 = 0.155，p = 0.01）与较低的GPA相关，但与PTSD症状无关（β权重 = -0.040，p = 0.62），尽管抑郁和PTSD症状的交互作用与GPA呈非显著的负相关（β权重 = -0.378，p = 0.08）。更严重的抑郁与作业迟交（β权重 = 0.171，p = 0.03）、考试不及格（β权重 = 0.188，p = 0.02）和逃课（β权重 = 0.254，p = 0.01）相关。抑郁与自我报告的GPA之间的关系由考试不及格的频率介导。结果表明，情绪困扰较大的学生军人及退伍军人学业表现也较差。
