Abstract

American Indian people have high suicide rates. However, little epidemiological data is available on depression prevalence, a suicide risk factor, in this population. Some research suggests that depression scales may perform differently for American Indian people. However, the Patient Health Questionnnaire-9 (PHQ-9), a depression scale widely-used in clinical practice, had not been assessed for cross-cultural measurement invariance with American Indian people.
