Strategies are needed to reduce the availability and promotion of alcohol on and around university campuses in New Zealand. Given the high prevalence of binge drinking in high school and its strong association with later binge drinking, strategies aimed at youth drinking are also a priority. In universities, high-risk drinkers should be identified and offered intervention early in their undergraduate careers.

Although day laborers are likely to suffer from high rates of work-related stress, there are no survey measures that focus on stress among this occupational group. Accordingly, we tested the validity and reliability of the Migrant Stress Inventory (MSI), a scale originally designed for migrant farmworkers. Based on survey data collected from day laborers (N = 102) in two Northern California communities, the MSI was found to have adequate internal consistency, yet additional analyses indicated a different factor structure for the subscales. New subscales (relationships, communication, alcohol and other drug use, years in the United States, age, deportation concerns, discrimination experience) with this sample had strong reliability, as well as construct validity. In all, 57.8% of day laborers experienced high rates of stress, and factor analysis differentiated four stressor domains: instability, relationships, communication, and alcohol and other drug use. Moreover, 39.2% of respondents reported lifetime difficulties with alcohol, although alcohol difficulties were not associated with stress. Implications for further research are discussed based on these findings.

This study examines effects of a randomized controlled trial for an online, family-based prevention program for older teens, Smart Choices 4 Teens, on alcohol use and related outcomes. Families (N ϭ 411; teen age M ϭ 16.4, SD ϭ 0.5) were randomly assigned to the intervention or control condition in 2014 -2015. Both intent to treat (ITT) and dosage models were conducted. ITT models: At the 6-month follow-up, teens in the experimental condition reported fewer friends who had been drunk, and parents in the experimental group reported more communication about social host laws. At the 12-month follow-up, parents in the experimental condition reported consuming fewer drinks than parents in the control group. Dosage models: At the 6-month follow-up, dosage was inversely related to teen drinking in the past 6 months or 30 days, frequency of teen drinking during the past 6 months and 30 days, drinks consumed by teens over the past 6 months, teen drunkenness and binge-drinking during the past 30 days, teen reported communication about safe drinking and positively related to parent and teen reported communication about social host laws. At 12 months, dosage was inversely related to teen alcohol use, frequency of teen drinking over the past 30 days, drinks consumed by teens over the past 6 months and 30 days, and teen drunkenness over the past 6 months. Results suggest that Smart Choices 4 Teens is beneficial for families. Dissemination and implementation strategies that motivate completion of program content will improve outcomes related to older teens' alcohol use.
