Historically, non-Indigenous researchers have often used methods rooted in colonization, which can misrepresent or ignore Indigenous knowledge and history, causing harm. In response, Indigenous communities and scholars have developed Indigenous and decolonizing methodologies to prevent harmful practices and support ethical research. 

Decolonizing methodologies reshape Western scientific approaches within a pro-Indigenous ethic, advocating for Indigenous self-determination. In contrast, Indigenous methodologies draw directly from Indigenous knowledge systems, independent of Western frameworks. 

The Wheel of AI/AN Specificity framework further ensures that research is conducted within Indigenous contexts, emphasizing collaborative relationships with tribal communities. This framework centers ongoing community engagement to align research with Indigenous practices, processes, and knowledge.

There is a critical need for more substance use epidemiological research in Indigenous communities that accurately reflects Indigenous communities. Existing data often suffer from major limitations, such as racial misclassification of American Indians, which leads to the underestimation of substance use-associated health issues and deaths. Epidemiological data collection at the state and national level often overlooks or marginalize Indigenous populations, with American Indians frequently classified as “Other Race(s)” or recorded only in footnotes as “insufficient numbers.” 

This subcore aims to support data that better support health initiatives and policies for Indigenous communities.

Multilevel modeling (MLM) is a statistical approach that accounts for nested data, such as individuals within communities or tribes, or in longitudinal studies where data is collected on the same individuals at multiple time points. Mixture models are a useful method for identifying clusters of individuals that share common elements (e.g., substance use attitudes, growth trajectories). Both methods allow researchers to examine different patterns in outcomes of interest (e.g., variance, response patterns across a set of observed variables). These approaches support culturally responsive research that can inform community-centered health interventions. 

Key Techniques

• Multilevel Modeling (MLM): Enables analysis across different levels such as within-groups and between-groups. By examining variance at multiple levels, MLM allows us to understand how individual factors may interact with community influences to shape health outcomes. 
• Mixture Models: These models identify latent heterogeneous subgroups across a set of observed indicators, such as substance use patterns (e.g., polysubstance use), attitudes, or beliefs. 
  • Latent Class/Profile Analysis (LCA): A primary method used to identify latent heterogeneous groups based on observed behaviors or beliefs, such as substance use patterns or intervention attitudes. 
  • Growth Mixture Modeling: A method for identifying heterogeneous groups of individuals who share common growth patterns on a single observed indicator (e.g., substance use frequency across adolescence).

Over the past 50 years, there has been significant progress in Indigenous self-determination and the reclamation of cultural identity and traditional knowledge. This has led to the concept of Indigenous Data Sovereignty, which refers to Indigenous Peoples’ authority over information derived from its territories, citizens, communities, and collective interests. This includes data generated by Indigenous Peoples, as well as by governments and other institutions.  

Currently, most Indigenous data are secured by non-Indigenous governments, institutions, and agencies, highlighting the need for increased participation in data governance processes. This includes both the stewardship and the processes necessary to implement Indigenous control over Indigenous data (collection, storage, analysis, use, reuse).
