简要总结
A randomized controlled trial to test the effects of culturally appropriate nutrition communication for Mexican American women.
详细描述
An unbalanced randomized controlled trial with pre-test and immediate post-test was employed to test the effects of different types of message features and appeals. The study was conducted online with Mexican American women aged 18-29 years old. Messages focused on sugary beverage consumption and the main outcomes were acceptance and receptivity to the message (i.e., perceived effectiveness), perceptions of social norms, and knowledge. The investigators also measured a number of hypothesized mediators and moderators of the effects.

结局指标
主要结局
Perceived effectiveness
时间窗: Immediately post-intervention
Perceived effectiveness of the message is known to affect intention to engage in a given health behavior. Therefore, perceived effectiveness of the stimuli was assessed as a proxy measure for intention to reduce sugary beverage consumption using a 5-point, 13-item Likert scale with responses ranging from Strongly Agree=5 to Strongly Disagree=1. This scale comprised 3 subscales namely (1) Message Acceptance - 2 items, (2) Argument Strength - 4 items, (3) Personalized Perceived Effectiveness - 7 items. Greater scores on this scale represented greater levels of perceived effectiveness of the message.
