This assessment encompasses the evaluation of a health media campaign that targeted African Americans in New Orleans following Hurricane Katrina. Analysis of panel survey data indicated a significant over-time increase in neighborliness but not social support. Among the

Similarly, among the three synchronous effect models of influence, the best fit was of the mass media use causes social capital model. This analysis provides support for the media campaign's effectiveness and, more broadly, allows for the extension of recent research that has used panel data to strengthen inferences of causation in different mass communication scenarios." Wei, Ran; Lo, Ven-Hwei; Lu, Hung-Yi: Reconsidering the Relationship Between the Third-Person Perception and Optimistic Bias. -S. 665-684 "Studies disagree as to whether an optimistic bias can account for the commonly observed third-person perceptions. This study aims to help clarify the relationship between third-person perceptions and biased optimism in the context of assessing the impact of the news about bird flu outbreaks in Taiwan. Using a random sample of 1,107 college students, third-person perception and optimistic bias were found to be robust but unrelated. Although both optimistic bias and third-person effect are psychological perceptual judgments that can be attributed to self-serving motivation, the third-person perception is a biased interpretation of media influence, while biased optimistic perceptions are a social psychological mechanism of bolstering self-esteem in self-other comparisons regarding a risk."
