Self-efficacy (continuous scale; Facebook group only)
Participants will answer questions about self-efficacy regarding weight gain, exercise and diet.
15 minutes
Sources of information about health during pregnancy (categorical variable; clinic and social network groups only)
Participants will answer questions about what sources of health information are provided by social network contacts during pregnancy.
15 minutes
Content of health information from interpersonal sources during pregnancy (free text variable; clinic and social network groups only)

Study Arms (3)
Facebook Survey Group
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
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
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.
Interventions
Participants view 1 of 6 brief video messages about health in pregnancy, then answer survey questions that will assess their a) acceptability, b) understanding of core messages, and c) self-efficacy about healthy eating, exercise and weight gain during pregnancy.
Participants view 1 of 6 brief video messages about health in pregnancy, then answer survey questions that will assess their a) acceptability, b) understanding of core messages, and c) who in her social network she turns to for non-clinical health advice and what kinds of advice she gotten in the past.

Eligibility Criteria
Women recruited via either the social media, clinical, or online approach will be eligible for participation if they are aged 18 years and older, pregnant, and English-speaking. Women will be excluded if they deny being currently pregnant, do not identify as living in the US and aged 18 years or older, or if they report having previously participated in the study. The Qualtrics survey will automatically conclude if potential participants provide answers to screening questions that deem them ineligible. Participants will not be excluded based on racial-ethnic groups. Males will be excluded, as this is a study involving pregnant women.
