Communication Mediation Model of Late-Night Comedy
Unformatted Document Text:  COMMUNICATION MEDIATION MODEL OF LATE-NIGHT COMEDY 16 To measure television news exposure, respondents were asked how often they used national nightly news and local television news on a 5-point scale, and responses on these two items were averaged to form an index (M = 3.55, SD = 1.44, α = .79).

items were averaged to form an index (= 3.55, SD = 1.44,

measured by one item asking respondents how often they used daily newspaper on a on a 5-point 
scale (= 3.59, SD = 1.44).

Analyses control for a host of demographic variables, including age (M = 49.24, SD = 
15.30), gender (46% female), race (75% white), household income (Median: $55,000), and 
education (Median: ‘some college or associate degrees’).  The model also controlled for party 
affiliation (33% Republican, 31% Democrat) and political interest measured on a 6-point scale 
(M = 3.50, SD = 1.71).
