Background: There are large disparities between immigrants and native Norwegians in domains such as health, education, and employment. Reducing such disparities is essential for individual and societal well-being. Social capital is associated with positive effects on these domains, and mentoring programs have the potential to boost social capital. However, few studies have assessed mentoring as a social capital intervention among youth or the potential barriers and facilitators of implementing digitally augmented mentoring.

Objective: The goal of this paper is to describe a protocol for assessing the implementation and effectiveness of a digitally augmented mentoring program for immigrant youth as a health intervention to promote social capital. The two-stage analytical framework for a pilot study followed by a randomized controlled trial (RCT) is presented. The pilot aims to assess program fidelity and make necessary intervention adjustments before the RCT. The RCT aims to assess the effects of the implemented intervention program on social capital and the relationship between program fidelity and effects.

Methods: Both the pilot and RCT will use mixed methods with a process evaluation approach used to structure the intervention and a pre-post test survey component to measure social capital and fidelity of program implementation. Interviews will also be used to enrich the quantitative data from the survey.

Results: The pilot study is scheduled to begin in fall 2019. Based on data analyses in spring 2020, potential adjustments will be made to the intervention, with findings used in preparation for the full-scale RCT study.

Conclusions: Digitally enhanced mentoring programs may be a helpful intervention for providing immigrant youth with tools for increasing their social capital and indirectly improving health outcomes. This protocol provides new knowledge about the implementation and evaluation of such programs.
