The American Indian and Alaskan Native population of the United States have experienced, across many generations, traumatic events that have left an enduring mark. These include massacres, forced removal from homelands, requiring Indian children to attend boarding schools, prohibition of spiritual practices, and other acculturation strategies. Therefore, understanding that American Indian elders living today may have experienced various traumatic experiences while living on a reservation, an exploration into the experiences across the life span of Lakota elders living on the Pine Ridge Indian reservation in South Dakota was conducted. Utilizing Indigenous methodologies and in-depth interviews with 25 Lakota elders aged 55–98 years, this qualitative study explored the traumatic events across the elders’ life span. A predominant theme emerged related to traumatic experiences of forced removal of families living in a community on the reservation, the Wounded Knee Massacre of 1890, and experiences related to boarding school. Learning more about these life experiences and developing treatment practices tailored to American Indian elders’ unique experiences is imperative.(PsycInfo Database Record (c) 2021 APA, all rights reserved)
