Abstract：
OBJECTIVE: The purpose of this study was to identify demographic variables, the level of self-directed learning (SDL), locus of control (LOC), and personality traits in dental hygiene (DH) students and to identify predictive variables for SDL.
METHODS: Cross-sectional survey research was conducted with a convenience sample of DH students (n = 229) in the United States using a web-based survey. The validated instruments used were the Self-Directed Learning Instrument (SDLI) to determine level of SDL, the Academic Locus of Control (ALC) scale for college students to evaluate LOC, and the Big Five Inventory-2-Extra Short Form (BFI-2-XS) to identify personality traits. Descriptive, correlation, and regression analyses were performed.
RESULTS: The completion rate was 68.9% (n = 159). The average SDLI score of the sample was 82.59, indicating a high overall level of SDL. The average ALC score was 10.34, indicating an overall internal LOC. Internal LOC (B = -0.319, SE = 0.082, β = -0.330, p < 0.001) and an open-minded personality trait (B = 1.156, SE = 0.363, β = 0.233, p = 0.002) emerged as significant predictors of learning motivation (B = -0.138, SE = 0.057, β = -0.214, p < 0.017) and self-monitoring (B = 0.553, SE = 0.253, β = 0.167, p = 0.030) SDLI constructs.
CONCLUSIONS: SDL among DH students can be cultivated by enhancing their learning motivation and self-monitoring skills. This may be achieved by helping learners increase their internal locus of control and open-mindedness. Future studies should explore exercises to help promote these traits.

摘要：
目的：本研究的目的是确定人口统计学变量，自我导向学习(SDL)的水平，控制源（LOC），和口腔卫生（DH）学生的个性特征，并确定SDL的预测变量。
方法：横断面调查研究是使用基于网络的调查对美国DH学生（n=229）进行的便利样本进行的。使用的经过验证的仪器是自我指导学习仪器(SDLI)，用于确定SDL的水平，大学生学术控制源(ALC)量表评估LOC，和大五量表-2-额外简短形式(BFI-2-XS)来识别人格特质。描述性的,相关性，并进行回归分析。
结果：完成率为68.9%（n=159）。样品的平均SDLI评分为82.59,表明SDL的总体水平较高。平均ALC评分为10.34,表明总体内部LOC。内部LOC（B=-0.319，SE=0.082，β=-0.330，p<0.001）和开放的人格特质（B=1.156，SE=0.363，β=0.233，p=0.002）是学习动机（B=-0.138，SE=0.057，β=-0.214，p<0.017）和自我监控（B=0.553，SE=0.167，p=β
结论：DH学生的SDL可以通过增强他们的学习动机和自我监控能力来培养。这可以通过帮助学习者增加他们的内部控制和开放心态来实现。未来的研究应该探索练习来帮助促进这些特征。
