There are several limitations associated with this study. Participants were recruited from a single site and self-selected to attend a focus group and/or complete the survey, thereby limiting the generalizability of our results. In addition, the parent study was designed with different foci, so we did not prevent family members with a
diabetes diagnosis from attending the same focus group. Three couples and one pair of sisters attended focus groups together, which may have increased discussion about family members’ supportive behav- iors or decreased discussion about family members’ nonsupportive behaviors. In qualitative research, saturation is reached when data collection no longer yields new results (27). The parent study ach- ieved saturation regarding the use of health information technology to manage diabetes. We achieved saturation regarding the role of family members’ supportive be- haviors, but have likely only begun to un- derstand the role of family members’ nonsupportive behaviors and miscarried help.
