Non-parent mentoring relationships are important protective factors for first-generation college students. Previous research has focused on singular mentoring relationships measured at one time point, failing to capture the breadth and dynamic nature of social networks. The current study is a longitudinal investigation of first-generation students’ mentoring networks during their transition to college at a four-year, predominantly minority-serving commuter university. At the beginning and end of their first year, students (N = 176) responded to online surveys on their mentoring relationship(s), attitudes toward help-seeking, and college experiences. Cumulative support from pre-college mentoring relationships retained across the first year was positively associated with self-efficacy. Support from newly acquired mentoring relationships was positively associated with psychological sense of school membership. Network orientation was positively associated with self-efficacy and sense of school membership. These findings highlight the importance of diverse mentoring networks and demonstrate the utility of collecting longitudinal data on multiple mentoring relationships.

非父母师徒关系是第一代大学生的重要保护因素。先前的研究侧重于在一个时间点衡量的单一指导关系，未能捕捉到社交网络的广度和动态性质。目前的研究是对第一代学生在四年制、主要为少数民族服务的通勤大学过渡到大学期间的指导网络的纵向调查。在第一年的开始和结束时，学生 (N = 176) 回应了关于他们的指导关系、对寻求帮助的态度和大学经历的在线调查。第一年保留的大学前指导关系的累积支持与自我效能呈正相关。来自新获得的指导关系的支持与学校成员的心理感觉呈正相关。网络导向与自我效能感和学校成员感呈正相关。这些发现强调了多样化指导网络的重要性，并证明了收集关于多种指导关系的纵向数据的效用。
