Table 4 Effects of package design elements on outcome variables estimated through regression analyses by comparing across experimental conditions (Based on the results in Table 3)
Condition 1 vs. Condition 2 (Column (1)): | Combined health warning compared to text-only warnings (on packages with brand logos) | More negative affect (at 10% statistical significance) |
Condition 2 vs. Condition 3 (Column (2)): | New warnings compared to old warnings (on packages with brand logos) | More negative affect and avoidant responses |
Condition 2 vs. Condition 4 (Column (2)): | PP compared to branded packages (when old warnings are displayed) | More negative affect and avoidant responses |
Condition 3 vs. Condition 5 (Column (3)): | PP compared to branded packages (when new warnings are displayed) | No effect on any of the outcome variables |
Condition 4 vs. Condition 5 (Column (4)): | New warnings compared to old warnings (on plain packages) | No effect on any of the outcome variables |
