The fact that many sub-populations do not take part in research, especially participants from lower socioeconomic (SES) backgrounds, is a serious problem in education research. To increase the participation of such groups we must discover what social, economic and practical factors prevent participation, and how to overcome these barriers. In the current paper, we review the literature on this topic, before describing a case study that demonstrates four potential solutions to four barriers to participation in a shared reading intervention for families from lower SES backgrounds. We discuss the implications of our findings for familybased interventions more generally, and the difficulty of balancing strategies to encourage participation with adhering to the methodological integrity of a research study.
