DESCRIPTION (provided by applicant): Young adult Mexican American women (MA) with low levels of acculturation and literacy have high rates of obesity and experience disproportionate health burdens stemming from weight-related diseases. Although counter-intuitive, obesity has been reliably linked to eating disordered (ED) behaviors, such as binge eating, fasting and self-induced vomiting, and, recent studies show that high BMI, tobacco and alcohol use are strongly associated with bulimia nervosa and binge eating disorders in low literate MA women. Despite evidence linking obesity to ED behaviors, tobacco and alcohol use, few studies have addressed these behaviors in low literate MA women and cutting-edge methodologies to reliably measure risk behaviors have not been extended for use with this at-risk population. The purpose of this study is to develop a cellular phone application to measure ED behaviors, alcohol and tobacco use and their determinants (affect and social context) as they occur in the natural environment and evaluate feasibility and acceptability of this measurement approach in low literate young adult MA women. Four specific aims will be addressed: 1) Develop a cellular phone application to measure ED behaviors, alcohol, tobacco use, mood and social context in low literate young adult MA women, 2) Using the cellular phone application in a pilot study of 58 low literate MA women (18-35 yrs), collect preliminary data on: a) patterns of ED behaviors, alcohol and tobacco use, b) mood and social contexts that precede ED behaviors, and c) validity and reliability of the measurement approach, and 3) Assess adherence and usability of cellular phone to measure ED, alcohol and tobacco use behaviors after 15-day pilot study. A Google Nexus One smartphone will be used as the measurement hardware and a user-centered, iterative design process will be used to develop the application interface. The development process is guided by the bioecological model and consists of 5 phases including: 1) a needs analysis with the research team, 2) development of initial designs and completion of a small user-study (n=8) to evaluate, 3) revision of design and completion of second user evaluation study (n=8) , 4) beta-testing with research team and 5-day testing with MA women (n=3), and, 5) 14-day pilot test of the application with a sample of 58 low acculturated and low literate young adult MA women. This project has the potential to change and improve measurement of health behaviors and health related phenomena in diverse low literate populations who have historically been difficult to study. Furthermore, a "user friendly cellular phone device will enable in vivo measurement of socially situated dynamic processes to uncover explanatory mechanisms predicting targeted risk behaviors in highly vulnerable and understudied populations.

描述（由申请人提供）：年轻的成年墨西哥裔美国妇女（MA）具有较低水平的适应性和识字率的肥胖症率很高，并且由于与体重相关的疾病所致。尽管违反直觉，但肥胖与饮食失调（ED）行为有可靠的联系，例如暴饮暴食，禁食和自我引起的呕吐，并且最近的研究表明，高BMI，烟草和饮酒与矮牛肉的神经性和暴饮暴食障碍密切相关。尽管有证据表明肥胖与ED行为，烟草和酒精的使用，但很少有研究能够解决识字率低的妇女中的这些行为和尖端的方法，以可靠地衡量风险行为，尚未扩展到这种高危人群中。这项研究的目的是开发一种蜂窝电话应用，以测量它们在自然环境中发生的行为，酒精和烟草的使用及其决定因素（情感和社会环境），并评估这种测量方法的可行性和可接受性。将解决四个具体目的：1）开发一种蜂窝电话应用，以衡量低知识年轻的成年妇女的饮酒，酒精，烟草使用，情绪和社交环境，2）在一项针对58名低知识妇女（18-35 YRS）试验性研究中使用蜂窝电话应用，收集以下情况： c）测量方法的有效性和可靠性，以及3）评估15天试点研究后的蜂窝电话，酒精和烟草使用行为的依从性和可用性。 Google Nexus One智能手机将用作测量硬件，并以用户为中心的迭代设计过程来开发应用程序接口。开发过程以生物生物学模型为指导，由5个阶段组成，包括：1）与研究团队的需求分析，2）开发初始设计和完成少量用户研究（n = 8）以进行评估，3）修订第二个用户评估研究（n = 8），对研究团队进行第二次测试和5日测试的应用程序，5-3）的应用程序（n = 3），N = 3），n = 3），n = 3），n = 3），n = 3），n = 3 = 3），n = 3），n = 3 = 3），n = 3 = 3），n = 3 = 3），n = 3 = 3），n = 3 = 3），以及n = 3），n = 3），n = 3 = 3），n = 3）；样本的58个低适应性和低识字年轻的成年女性妇女的样本。该项目有可能改变并改善对健康行为和与健康相关的现象的衡量，这些现象在历史上很难研究。此外，“用户友好的蜂窝电话设备将使社会位置的动态过程进行体内测量，以揭示预测高度脆弱和研究型人群中有针对性风险行为的解释机制。 公共卫生相关性：较低的适应和识字率的年轻墨西哥裔美国妇女（MA）的肥胖症率很高，并且由于体重相关疾病而导致的健康负担不高。该项目有可能改变并改善对健康行为和与健康相关的现象的衡量，这些现象在历史上很难研究。此外，一种“用户友好”的蜂窝电话设备将使社会位置的动态过程进行体内测量，以发现易受伤害和研究的人群中有针对性的风险行为的解释机制。
