This study tests the hypotheses that both social/cultural contexts and individual dispositional characteristics may interact with program content to produce effects that are variable in potentially predictable ways.

Three-way linear and nonlinear interactions, program frame x social context x dispositional phenotype, were tested. Results: Three-way interactions were found for the dispositional phenotypes of depression and hostility with social context and program content/frame. In predominantly Hispani
