Detaljert beskrivelse
The purpose of this study is to apply and investigate the feasibility of a social media and text-message-delivered, Social Cognitive Theory-based, culturally relevant intervention designed to promote physical activity among African American women. In an 8-week, 2-arm randomized trial, 30 African American women will be assigned to receive either: a) culturally-relevant, technology-based physical activity intervention delivered via Facebook and text messages, or b) a standard print-based physical activity promotion intervention consisting of high quality physical activity promotion brochures produced by the American Heart Association delivered via USPS mail.
Aim 1: Test the feasibility of a culturally relevant, social media and text-message delivered physical promotion pilot intervention among adult African American women. The investigators hypothesize that the culturally relevant Facebook and text message delivered intervention will be feasible as measured by the acceptability, implementation, and practicality of the intervention program.
Aim 2: Examine the impact of the culturally-relevant, Facebook and text message delivered intervention to increase physical activity and enhance associated Social Cognitive Theory constructs explicitly targeted by the intervention activities. Physical activity will be objectively measured by accelerometers and Social Cognitive Theory constructs of self-efficacy, social support, self-regulation, and outcome expectations will be assessed by validated self-report questionnaires. The investigators hypothesize that participants receiving the culturally-adapted, Social Cognitive Theory-based Facebook and text-message intervention will demonstrate higher physical activity levels and greater enhancements in Social Cognitive Theory constructs when compared to the standard print-based intervention group at the post-intervention assessment.
Aim 3: Examine the preliminary effect of a culturally relevant, social media-delivered physical activity promotion intervention on anthropometric, blood pressure, and blood lipid outcomes. The investigators hypothesize that increased physical activity at the post-intervention follow-up will be associated with improvements in these variables.

|---|---|

Eksperimentell: Facebook and Text Message
Participants randomized to the technology-based physical activity intervention will receive a culturally-relevant physical activity promotion intervention delivered via text messages and the social media website Facebook.
The purpose of the intervention materials is to encourage participants to achieve a minimum of 150 minutes/week of moderate-intensity aerobic physical activity each week.

Aktiv komparator: Standard Print-based Intervention
Participants randomized to the standard print-based physical activity intervention group will be mailed 4 self-help booklets promoting physical activity produced by the American Heart Association.
Booklets will be mailed one at a time in 2 week intervals over the 1st 6-weeks of the intervention.
These high quality booklets provide general information on the benefits of physical activity, tips and strategies to increase daily physical activity, and encourage recipients to perform a minimum of 10,000 steps per day.

Feasibility of Using Facebook and Text Messaging to Deliver a Physical Activity Program to African American Women
Tidsramme: Post Intervention (up to 8 weeks)
|
Measured using a composite score by assessing acceptability (participants perceived satisfaction and usefulness of the program; perceived cultural relevance of the program), demand (interest in study participation; participant retention), and implementation (participant activity on the Facebook group page, successful delivery of text messages, successful delivery of study materials on the study Facebook wall) of the culturally relevant physical activity program.
