Advancing methods for program evaluation in substance use by strengthening the application of epidemiology, economic evaluation, and implementation science
A Latent Class Analysis of Prevention Approaches Used to Reduce Community-Level Prescription Drug Misuse in Adolescents and Young Adults
Evaluating Mediated Perception of Narrative Health Messages
Narrative media health messages have proven effective in preventing adolescents' substance use but as yet few measures exist to assess perceptions of them. Without such a measure it is difficult to evaluate the role these messages play in health promotion or to differentiate them from other message forms. In response to this need, a study was conducted to evaluate the Perception of Narrative Performance Scale that assesses perceptions of narrativ…
Ethnic Identity Development and Acculturation
Utilizing part of the survey data collected for a National Institute on Drug Abuse (NIDA)- funded project from 29 public elementary schools in Phoenix, Arizona ( N = 1,600), this study explored the underlying structure of Mexican-heritage youths' ethnic identity and cultural/ linguistic orientation. Latent profile and transition analyses identified four distinct orientation profiles endorsed by the early adolescents and their developmental trends…
Using a Nonparametric Bootstrap to Obtain a Confidence Interval for Pearson’s r with Cluster Randomized Data
Acculturation Status and Substance Use Prevention with Mexican and Mexican-American Youth
This study examined whether language preference, as an indicator of acculturation, moderated the effects of a culturally grounded substance use prevention intervention for Mexican and Mexican American middle school students (N = 2,146) in Phoenix, Arizona. The main hypothesis was that levels of program effectiveness would vary based on the language preference of the students and the specific culturally grounded version of the intervention they we…
Methods for Handling Missing Data
This chapter describes a general approach to handling missing data in psychological research. It provides a theoretical background in readable, nontechnical fashion. Our overall goal was to give practical, usable advice, rather than to give a detailed statistical treatment of issues surrounding analysis of incomplete data. We give an overview of the older, unacceptable methods for handling incomplete data, so that readers will know what approache…
