Prevalence Estimation: The BDI helps estimate the prevalence of depression in various populations, such as adolescents, adults, and the elderly. Risk Factor Identification: By correlating BDI scores with demographic, genetic, and environmental factors, researchers can identify potential risk factors for depression. Intervention Assessment: The BDI is used to evaluate the effectiveness of public health interventions aimed at reducing depression rates. Longitudinal Studies: The BDI can track changes in depressive symptoms over time, providing insights into the natural history of depression and the long-term impact of treatments.
