Completed

• Conditions: Pregnancy; Weight Gain
• Interventions: Behavioral: Responses to Brief Video Messages (Facebook); Behavioral: Response to Brief Video Messages (Clinic); Behavioral: Response to Brief Video Messages (Social Network)

• Registration Number: NCT02490579
• Lead Sponsor: University of Michigan

Brief Summary

The primary purpose of this study is to assess the responses of pregnant women and their social network to six videos about health in pregnancy. Our goal is to assess a) acceptability and b) understanding of core messages about healthy eating, exercise and weight gain during pregnancy. We will also assess c) non-clinical sources of health information during pregnancy.

Detailed Description

Many women engage in suboptimal lifestyle behaviors during pregnancy. Many women do not realize that unhealthy diet, exercise and weight gain behaviors can be dangerous for their pregnancy and have harmful long-term consequences for their baby. There is great need for strategies to promote accurate knowledge about healthy behaviors during pregnancy. The purpose of this study is to assess responses to a brief (\<1minute) video about healthy behaviors during pregnancy. The study sample will include pregnant women and members of their social network. Participants will be asked to watch a brief video and complete an anonymous online survey measuring their response to the video, and their basic demographics. The surveys will also assess how family and friends impact pregnant women's health behaviors. Online surveys are entirely anonymous. We will recruit pregnant participants from two sources: the University of Michigan Health System's prenatal clinics and a social media website (Facebook).

Arm && Interventions

Group	Intervention	Description
Facebook Survey Group	Responses to Brief Video Messages (Facebook)	During June, 2015, approximately 1200 women will be recruited through Facebook advertisements targeted at English-speaking women age 18-50 years living in the United States. Advertisements will contain 3 key features: an image, a caption, and "ad copy" followed by a link to the survey website. Individuals who click on the study link in the advertisement will be redirected to the study's Qualtrics web page where they will take a 15 web-page, multiple choice survey developed by the research team. The survey covers these domains: reaction to video, understanding of core message, self-efficacy around lifestyle behaviors, attitudes, beliefs and intentions regarding vaccination during pregnancy, key health information sources during pregnancy, and demographics.
Clinical Survey Group	Response to Brief Video Messages (Clinic)	During June-August, 2015, approximately 500 women will be recruited at routine obstetric visits to the University of Michigan's outpatient clinics. Women who check in for an Ob appointment will be offered the opportunity to participate in an anonymous online survey. Individuals who express interest in participating will be provided with a laptop and headphones and directed to the survey Qualtrics site where they will take a 15 web-page, multiple choice survey developed by the research team. The survey covers these domains: reaction to video, understanding of core message, self-efficacy around lifestyle behaviors, attitudes, beliefs and intentions regarding vaccination during pregnancy, key health information sources during pregnancy, and demographics.
Social Network Group	Response to Brief Video Messages (Social Network)	Once a pregnant participant completes the survey, she will be asked to provide her email address. If she is willing to do so, Qualtrics will automatically send her an email containing a weblink to the survey for her social network. She can then provide this link to 1 or 2 social network members that she feels influence her health behaviors during pregnancy. These members are asked similar questions about their response to the video, as well as some additional questions about how they advise their pregnant person about different health topics. It is necessary to provide a unique weblink to her, so that the survey responses from the pregnant woman and her unique social network members can be linked.

Primary Outcome Measures

Name	Time	Method
Self-efficacy (continuous scale; Facebook group only)	15 minutes	Participants will answer questions about self-efficacy regarding weight gain, exercise and diet.
Sources of information about health during pregnancy (categorical variable; clinic and social network groups only)	15 minutes	Participants will answer questions about what sources of health information are provided by social network contacts during pregnancy.
Perceived impact of interpersonal health advice on health behaviors during pregnancy (categorical and free text variables; clinic and social network groups only)	15 minutes	Participants answer questions about the impact the health information and advice they receive from social network contacts during pregnancy has on their behavior.
Content of health information from interpersonal sources during pregnancy (free text variable; clinic and social network groups only)	15 minutes	Trained research assistants will review answers to questions about the types of health information and advice are provided by social network contacts during pregnancy.
Composite acceptability score (continuous variable)	15 minutes	Participants will be asked questions about their reaction to the video.
Understanding of core messages (free text item; categorical items)	15 minutes	Trained research assistants will review answers to questions regarding diet, exercise and weight gain in pregnancy to determine whether individuals understood/did not understand the core message.
