The social construction explanation of social problems offered by Blumer (1971) and Spector and Kitsie (1977) has been criticized (cf. Best and Horiuchi 1985) for lacking a conception of extra-media influences that can affect audiences beyond the initial viewing situation. Recent work in mass communication indicates that a media logic is adapted by other institutions to amplify television imagery and themes about crime, danger, and child abuse. A case study of the origins and claims and counterclaims about the nature and extent of missing children is combined with an empirical analysis of the impact of various sources of information about the missing children issue in order to demonstrate the process by which a social problem is constructed. The impact of additional information is analyzed by administering a self-report questionnaire to 96 respondents before and after viewing a two-part documentary on the complexities of the issue. The data suggest that mass-mediated imagery and formats forge an interactive informational context for social problems by sustaining what is viewed in one's living room with imagery in bulk mail, milk cartons, and posters. It is further suggested that mass media depictions of problems such as 'missing children' carry over into consonant images such as child abuse. This conceptualization is capable of encompassing other accounts of social problems (e.g., 'urban legends') within claims-making activity. (Author abstract)
