Using a national sample of 1225 Black/African American men, we investigated how network composition, support patterns, and perceived health behaviors within networks relate to diabetes self-efficacy. Results revealed complex relationships between social network characteristics and self-efficacy. Having highly supportive network members emerged as the strongest positive predictor of diabetes self-efficacy (β = 0.27, p < 0.001), followed by network members' perceived engagement in healthy eating (β = 0.17, p < 0.001). Having a higher proportion of friends in one's network was positively associated with self-efficacy (β = 0.08, p = 0.005), while having a higher proportion of infrequent contacts showed a negative association (β = - 0.15, p = 0.001).

The current study had two primary aims: first, to use qualitative data to enhance the quantitative understanding of types; and second, to describe qualitatively participants' own experiences with their family during a 9 month family-focused intervention (and 6 month follow-up) based on their diabetes-specific family functioning type at enrollment.

We recruited 77 participants across types to participate in semi-structured interviews at the completion of the follow-up. We found consistencies across types and differences between types. Regardless of type, harmful family involvement was described, but adults with T2D were hesitant to label it as such. Communication about diabetes and health increased during FAMS, but topics varied across types.

PF has been associated with improved QoL and functional outcomes and reduced psychological symptoms in individuals living with specific CHCs; yet its mediating role in these outcomes remains underexplored. This secondary analysis examined whether changes in PF mediated improvements in QoL, psychological symptoms, and functional impairment among individuals with various CHCs. Participants (n = 100) were randomized to a six-session self-guided, online ACT program or a waitlist control group. Outcomes were assessed at baseline, post-treatment, and four-week follow-up. Results revealed that increases in PF significantly mediated improvements in QoL, with indirect effects indicating that higher PF at post-treatment predicted better QoL at follow-up. The ACT group demonstrated significant reductions in functional impairment at follow-up compared to the waitlist group, though this effect was not mediated by changes in PF. Improvements in psychological symptoms were not statistically significant and were not mediated by PF. These findings suggest that ACT effectively enhances PF, which subsequently improves QoL in individuals with CHCs.
