Food Literacy Intervention - is a "Train the Trainer" Approach Feasible and Effective?

Официальное название

Food Literacy Intervention for Arab and Jewish Women in the Jerusalem Region - is a "Train the Trainer" Approach Feasible and Effective?

Обзор

Food literacy (FL) is the capability to make healthy food choices in different contexts, settings and situations. Although eating habits are shaped by different circumstances and skills, most nutrition programs focus on nutrition knowledge alone. Addressing factors such as competencies, self-efficacy and social norms enables sustainable positive change in nutrition behaviour. This study will assess a lay leader-led FL workshop to Arab and Jewish women from disadvantaged communities in the Jerusalem region, utilizing a train-the-trainer approach, and will compare the effectiveness and cost-effectiveness of a lay-led FL intervention to an expert-led intervention.

Подробное описание

Food literacy (FL) is the capability to make healthy food choices in different contexts, settings and situations. Although eating habits are shaped by different circumstances and skills, most nutrition programs focus on nutrition knowledge alone. Addressing factors such as competencies, self-efficacy and social norms enables sustainable positive change in nutrition behaviour. This study will assess a lay leader-led FL workshop to Arab and Jewish women from disadvantaged communities in the Jerusalem region, utilizing a train-the-trainer approach, and will compare the effectiveness and cost-effectiveness of a manualized FL intervention given by trained lay-leaders vs. the same workshop given by experts.

Вмешательства

• Поведенческое Lay-led FL workshops
  Groups of women recruited by trained lay-leaders will receive an 8-session lay-led FL workshop. Workshop participants will receive a self-report baseline survey at the first session, and post surveys at the last session and 3 months after the last session. The surveys will be anonymous and will be conducted and collected by the lay workshop facilitator. Lay-leaders will receive an incentive to collect surveys from workshop participants. A member of the research staff will be present at the time
• Поведенческое Expert-led workshops
  Matching groups of women recruited by research staff will receive the same 8-session expert-led FL workshop. Workshop participants will receive a self-report baseline survey at the first session, and post surveys at the last session and 3 months after the last session. The surveys will be anonymous and will be conducted and collected by the expert workshop facilitator.
