Patterns of Polysubstance Use Among Non-Hispanic White and American Indian/Alaska Native Adolescents: An Exploratory Analysis
ORIGINAL RESEARCH — Volume 16 — April 4, 2019
There are two 10 by 10 grids, one grid for American Indian/Alaska Native and another for non-Hispanic white. Each square in the grid represents a pair of drugs; thus, for each grid, there are 81 pairs. For each pair, a correlation coefficient (Spearman rho) is represented by a different color. There are 4 colors: one represents a Spearman rho ranging from 0 to <0.25; the next, 0.25 to <0.50; the next, 0.50 to <0.75, and the next, 0.75 to 1.00. The following 10 drugs are represented: alcohol, cigarettes, cocaine, ecstasy, heroin, inhalants, injected drugs, marijuana, methamphetamine, and steroids. There is no discernible pattern in general to the array of colors; however, in general, the coefficients appear to have higher values in the grid for American Indian/Alaska Native than for non-Hispanic white adolescents.
