Abstract

OBJECTIVE

High school youth have an elevated risk of substance use. Some substances (e.g., inhalants, MDMA) used by youth are overlooked or grouped in an "other" category. Compared to other racial/ethnic groups, American Indian (AI) youth may be at higher risk of using these substances. The purpose of this study is to examine the prevalence and patterns of use of "other" substances among youth living on or near reservations.

METHOD

This study uses data from Our Youth Our Future, a national probability sample survey of substance use among reservation-based youth (n = 14,769) to examine prevalence rates of use across sex (51% male), AI identity (61% AI), and their intersection within seven geographic regions of the United States.

RESULTS

Results indicate AI youth largely did not endorse "other" substance use at significantly higher rates than non-AI youth, although in two regions they held higher odds of use of any "other" substance compared to non-AI participants. In the Southeast and Northwest, AI youth were less likely to use prescription opioids and over-the-counter cold medicines than non-AI youth, respectively. Notable effects for sex emerged such that males in the Southwest were more likely to use inhalants, hallucinogens, and tranquilizers than female participants. Participants in the Southern Plains reported the highest prevalence of "other" substance use.

CONCLUSIONS

While overall risk of using "other" substances is similar between AI and non-AI youth in many regions, differences in use patterns by AI identity and sex can help target prevention and intervention efforts.

Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Surveys allow researchers to gather data from larger samples than may be afforded by...
