Methods: To evaluate the effectiveness of a culturally adapted intervention delivered by tribally based community health representatives (CHR)s, we used a longitudinal open-cohort stepped-wedge trial design (SWTD), situated within broader community-based participatory research (CBPR) to examine changes in life satisfaction, psychological resilience, family resilience, and perceived social and community support. Multilevel longitudinal modeling included the following results.
Results: Multilevel modeling indicated significant increases in family resilience (B = 0.45, p = .04) and in social, family, and community support (B = 0.13, p = .04) among adults in the study. Life satisfaction and psychological resilience improved through 6- and 9- months postintervention, respectively, yet did not reach statistical significance overall. Youth reported significant increases in life satisfaction (B = 0.34, p = .0003) and in psychological resilience (B = 0.57, p = .0001). Although family resilience and social support among youth did not reach statistical significance, both showed upward trends.
Conclusions and Implications: Given resilience has been found to be linked with better mental health and coping, such improvements indicated strong implications for improved wellness overall. Significant improvements in family resilience and perceived social, family, and community support among adults, and in life satisfaction and psychological resilience among youth, demonstrate the value of culturally grounded, community-based interventions. These findings corroborate with previous research indicating that resilience is a protective factor against mental health challenges, including depression, anxiety, and PTSD (Campbell-Sills, et al. 2006; Luo et al., 2025). Although gains were sustained for many participants, especially through 6- and 9-month postintervention timepoints, booster sessions with refresher courses may further sustain and extend initial postintervention gains.
