研究发现，非裔美籍Meyerhoff学者完成STEM博士学位的可能性是比较样本学生的4.8倍（研究1），项目组成部分的感知利益完全介导了社区意识与科学身份和研究自我效能之间的关系（研究2）。先前的研究表明，巴尔的摩县马里兰大学的迈耶霍夫学者计划对成绩优异的少数族裔（URM）学生是一种有效的干预；Meyerhoff的非裔美国学生比比较学生更有可能进入科学、技术、工程和数学（STEM）博士课程。本报告中的两项研究中的第一项扩展了先前的研究，通过检查前16个队列中Meyerhoff （N = 479）和比较样本（N = 249）学生的博士学位完成水平。进入迈耶霍夫学院的非裔美国学生完成STEM博士学位的可能性是对比样本学生的4.8倍。为了加深对潜在影响机制的理解，第二项研究使用了第22个（2010年秋季）至第25个（2013年秋季）队列（N = 109）的数据来检验大一期末项目利益感知会中介暑期桥结束时社区意识与大二期末科学认同和研究自我效能之间的关系的假设。研究2结果表明，项目利益感知完全介导了社区意识与两项标准测量之间的关系。研究结果强调了综合STEM干预计划提高博士学位完成率的潜力，并提出了影响机制。
Studies found that African-American Meyerhoff Scholars were 4.8 times more likely to complete STEM PhDs than comparison sample students (study 1) and that perceived benefits of program components fully mediated the relationship between sense of community and both science identity and research self-efficacy (study 2). Previous research has shown that the Meyerhoff Scholars Program at the University of Maryland, Baltimore County, is an effective intervention for high-achieving underrepresented minority (URM) students; African-American Meyerhoff students are significantly more likely to enter science, technology, engineering, and mathematics (STEM) PhD programs than comparison students. The first of two studies in this report extends the prior research by examining levels of PhD completion for Meyerhoff (N = 479) versus comparison sample (N = 249) students among the first 16 cohorts. Entering African-American Meyerhoff students were 4.8 times more likely to complete STEM PhDs than comparison sample students. To enhance understanding of potential mechanisms of influence, the second study used data from the 22nd (Fall 2010) to 25th (Fall 2013) cohorts (N = 109) to test the hypothesis that perceived program benefit at the end of freshman year would mediate the relationship between sense of community at the end of Summer Bridge and science identity and research self-efficacy at the end of sophomore year. Study 2 results indicated that perceived program benefit fully mediated the relationship between sense of community and both criterion measures. The findings underscore the potential of comprehensive STEM intervention programs to enhance PhD completion, and suggest mechanisms of influence.
