摘要	Media system dependency analysis operationalizes Ball-Rokeach and DeFleur's 1976 theory that media effects are strongest when individuals depend heavily on the media system to attain personal goals — understanding their world, orienting their actions, and finding diversion. The method surveys the intensity of these dependency relations and relates them to cognitive, affective, and behavioral effects of media.	The uses and gratifications survey is the dominant audience-centered method in communication research, asking not what media do to people but what people do with media. Codified by Katz, Blumler, and Gurevitch in 1973, it treats audiences as active agents who select media to satisfy social and psychological needs, and it measures those motives and the rewards obtained through structured self-report scales.
