Tóm tắt	A framing effects experiment is a randomized design that isolates the causal impact of how a message is framed — which considerations it emphasizes — on people's attitudes, judgments, or behavior. By randomly assigning participants to read otherwise comparable messages that differ only in their frame, it provides the causal counterpart to the descriptive framing analysis of media content.	Gain-loss message framing analysis is an experimental method for testing whether a persuasive appeal works better when it stresses the benefits of acting (gain frame) or the costs of not acting (loss frame). Grounded in prospect theory and synthesized for health communication by Rothman and Salovey, it predicts that loss frames are more persuasive for risky detection behaviors while gain frames win for safe prevention behaviors.
