Intensive Measurement of Drug Use During the Transition to Adulthood

描述（由申请人提供）：将通过高强度的基于网络的评估（即，测量突发设计）。由于向成年过渡的实验性质，包括缺乏对生活各个领域的永久角色承诺和探索，在生命历程的这一阶段需要进行这种高强度的测量。将讨论三个具体目标。(1)描述和解释物质使用在整个过渡出高中与动态运动到新的社会角色和环境。高中毕业后过渡期的密集数据将扩展现有长期纵向数据资源的已知内容，这些数据资源监测药物使用的长期趋势。(2)检查药物和酒精使用与其他健康行为（即，性、饮食、睡眠、身体活动行为）和后果（即，物质使用问题;在学校，工作和关系中的困难）。除了累积的发展 人与人之间和不同场合的趋势和行为对健康具有很大的可变性和影响。(3)通过记录初始响应率并调查基于网络的测量突发设计中重复评估对行为、响应模式和损耗的潜在影响，为方法学设计提供信息。该项目将提供资料，通过审查以下问题，支持调查研究方法和业务的进展：a）基于网络的调查是否是从高中过渡出来的不同学生群体的适当措施，B）在高强度和低强度测量条件下，学生是否可以适当地在这种过渡中被保留，以及c）随着时间的推移，密集测量条件如何影响自然减员和调查答复。参与者将在高中高年级完成基线调查，然后将接受为期14天的基于网络的日记测量三次（间隔4个月），以评估他们在学校，工作，家庭和关系中的经验，以解决目标1和2。为了解决目标3，随机选择一半的参与者将被分配到低测量强度亚组（即，基线后12个月的一次随访调查）作为对照组，以评估提供日常行为的强化报告对应答率和报告的行为的影响。本研究旨在通过记录高中毕业后过渡期的药物使用行为和后果的变化和模式，以及关于重复测量对反应影响的方法学贡献，对药物使用研究做出实质性贡献。 公共卫生相关性：本研究项目旨在通过检查高中毕业后过渡期的物质使用行为，为物质使用研究做出概念性贡献。高强度网络评估（即，测量突发设计）将用于记录物质使用、其他健康行为和社会角色变化的可变性和共变。此外，该项目将通过调查重复评估对行为，反应模式和磨损的潜在影响来告知调查研究方法。

DESCRIPTION (provided by applicant): Variability and co-variation in substance use behaviors across the transition out of high school will be examined by high-intensity web-based assessment (i.e., a measurement burst design). Such high-intensity measurement is required during this stage of the life course because of the experimental nature of the transition to adulthood, including lack of permanent role commitments and exploration in various domains of life. Three specific aims will be addressed. (1) Describe and explain substance use across the transition out of high school in relation to dynamic movement into new social roles and contexts. Intensive data across the transition out of high school will extend what is known from existing long-term longitudinal data resources that monitor trends in substance use across time. (2) Examine within-person associations of drug and alcohol use with other health behaviors (i.e., sexual, eating, sleeping, physical activity behaviors) and consequences (i.e., substance use problems; difficulties in school, work, and relationships). In addition to cumulative developmental trends, behaviors within-persons and across occasions have great variability and implications for health. (3) Inform methodological designs by documenting initial response rates and investigating potential effects of repeated assessments in a web-based measurement burst design on behaviors, response patterns, and attrition. This project will provide information to support advances in survey research methodology and operations by examining: a) whether web-based surveys are appropriate measures for a diverse population of students transitioning out of high school, b) whether students can appropriately be retained across this transition in both high- and low-intensity measurement conditions, and c) how intensive measurement conditions affect both attrition and survey responses over time. Participants will complete a baseline survey in senior year of high school, and then will be surveyed with 14-day web-based diary measurement bursts three times (at 4 month intervals) to assess their experiences in school, work, family, and relationships to address Aims 1 and 2. To address Aim 3, a randomly selected half of participants will be assigned to a low measurement intensity subgroup (i.e., one follow-up survey 12 months after baseline) to serve as a control group to assess the effects of providing the intensive reports of daily behaviors on response rates and reported behaviors. This study is designed to make a substantive contribution to substance use research by documenting variability and patterns of drug use behaviors and consequences across the transition out of high school and a methodological contribution regarding the effects of repeated measurement on response. PUBLIC HEALTH RELEVANCE: This research project is designed to make a conceptual contribution to substance use research by examining substance use behaviors across the transition out of high school. High-intensity web-based assessment (i.e., a measurement burst design) will be used to document variability and co-variation in substance use, other health behaviors, and social role changes. In addition, the project will inform survey research methodology by investigating potential effects of repeated assessments on behaviors, response patterns, and attrition.
