Summary View help for Summary
The Drug Use and Cultural Factors Among Hispanic Adolescents and Emerging Adults - Los Angeles, 2006-2016 collection examines the cultural risk and protective factors for substance use among Hispanic adolescents and emerging adults in Southern California. Adolescents were recruited in 9th grade and completed annual surveys about their substance use, acculturation, ethnic identity, cultural stressors, peer and family relationships, and cultural values. They were re-contacted to complete surveys in their early 20s; this survey also included measures of sexual behavior and interpersonal violence.
Demographic variables present in this collection include age, gender, grade in school, ethnicity, country of origin, education level, language spoken, socioeconomic status, marital status, sexual orientation, ZIP code, and place of residence.

Study Purpose View help for Study Purpose
Project RED aims to explore the relationship between acculturation and known psychological and social factors that influence the decisions that youth make about drug use. The primary objective is to better understand the risk and protective factors relevant to the population that attend the identified schools and incorporate findings in to the development of innovative drug prevention programs tailored to meet the specific needs of these students. Following the students through high school allowed researcher to better understand the etiology of risky as well as healthy behavior.
Sample View help for Sample
Researchers gathered participants from seven high schools in the Los Angeles area where the population is at least 70% Hispanic, as indicated by data from the California Board of Education. An eighth school was added to the sample in the second wave of the study. Sampling included an emphasis on schools with a wide range of socioeconomic characteristics. Census data was used to obtain an estimate of the median annual household incomes of the ZIP codes served by the schools. Participants enrolled in these high schools were included in the study during their 9th grade year, and only participants who initially self-identified as either Hispanic, Latino/a, Mexican, Mexican-American, Chicano/a, Central America, South America, Metizo, La Raza, or Spanish were retained for additional waves of the study.

Response Rates View help for Response Rates
In 2005, all 9th graders attending selected schools (n = 3218) were invited to participate in the survey. Of those, 75 percent (n = 2,420) provided parental consent and student assent. Of the 2,420 students who provided consent and assent, 2,226 (92 percent) completed the survey in 9th grade. Of the 2,226 students who completed the 9th grade survey, 1,773 (80 percent) also completed surveys in 10th and 11th grade with 182 (8 percent) students completing a survey in 10th grade but not in 11th grade, 50 students (2 percent) completing a survey in 11th grade but not in 10th grade, and 217 (10 percent) students lost to attrition before the 10th grade survey.
