Indigenous cultural erosion had become an alarming global concern. This study explored the lived experiences of the Dibabawon tribe and examined how modernization had altered their cultural identity. The research was conducted in Laak, Davao de Oro, and involved 12 selected individuals aged between 30 and 60 years. Data were gathered through in-depth interviews (IDI) and focus group discussions (FGD). Thematic analysis revealed three major themes: modernization as a structural determinant of social change, interaction with modernization as a process and mechanism of social change, and cultural erosion as a direction and consequence of social change. These themes yielded six, five, and six subthemes, respectively. An additional emerging theme—cultural resilience and adaptation strategies in response to social change—also surfaced, comprising four subthemes. The study recommended conducting regression analysis to assess how modernization and cultural resilience predicted cultural erosion, using its subthemes as observable indicators. Furthermore, mediation analysis was suggested to explore whether cultural resilience mediated the relationship between modernization and cultural erosion.
