The effectiveness of providing training and ongoing support to foster cultural humility in volunteers serving as mentors to youth of color: a mixed-methods study protocol

Background: The aim of this randomized control trial is to test the impact of providing additional training and support to volunteers who are paired with youth of color in the Big Brothers Big Sisters (BBBS) community-based mentoring program. The aim of the intervention activities is to enhance the capacity of mentors to have more culturally responsive and informed interactions with their mentees of color, thereby strengthening the youth's ethnic/racial identity and abilities to both cope with experiences of racism and contribute to causes that advance social justice.

Methods: Recruitment started in June 2022, with a goal of enrolling 240 dyads (i.e., "matches"), each consisting of a volunteer mentor and a youth of color aged 9- to 17-years old with whom they were paired through BBBS. Each match is assigned randomly to receive either standard BBBS services or to services that incorporate the intervention activities (i.e., approximately 3 h of initial training that is then supplemented with booster emails and in the context of the contacts that case managers have with mentors routinely in the program). The BBBS staff who are responsible for delivering the enhancements receive preparatory training as well as ongoing support with implementation. The study has a mixed-methods design. Survey data, on outcomes (e.g., ethnic/racial identity, sense of mattering, efficacy) aligned with the theory of change, are collected at multiple time points within 12 months from mentors, youth and their parent/guardian, and BBBS staff. Multiple qualitative interviews are conducted with a subset of youth, mentors, parents and BBBS staff to examine how the intervention works and how it impacts relationship development and youth outcomes over time. Integration of quantitative and qualitative data will aim to better understand whether and how the intervention works with respect to its potential influence on mentor attitudes (e.g., cultural humility), mentor-youth interactions, and emergent identities and capacities that have well-documented importance for the resilience and well-being of youth of color.

Discussion: This culturally tailored training and support intervention for volunteer mentors may be one way to increase the effectiveness of mentoring programs for youth of color. Study findings will have implications for youth mentoring programs and for other settings (e.g., schools, after school programs) in which children and adolescents form relationships with adults.
