Effects of mood and knowledge on evaluations: An experimental study

An experimental study was conducted to estimate the impact of subjects' mood states on their responses to evaluative ratings. Four experimental groups were induced by either a very negative, mildly negative, neutral or positive mood-inducing film. As hypothesized, systematic differences were found between the groups in their evaluations. Factual knowledge about the evaluation object was, contrary to expected, not found to modify mood effects. This negative finding could, however, be explained by a strong stereotypical impression of the object (a distant travel destination) held by the respondents.     

Gender Differences in Healthcare Utilization: The Mediating Effect of Utilization Propensity

To evaluate the mediating effect of utilization propensity (UP) on gender differences in healthcare utilization (HCU), a representative sample of the German general population (N = 2,510) was assessed with questionnaires. Gender differences in HCU, UP, and the mediating effect of UP were investigated using regression analyses. UP was significantly associated with HCU. The explanatory power of gender for UP, and of UP for HCU was prevailingly weak. UP had a mediating effect on gender differences in HCU, but the effect was very small. This is partly attributable to common problems in the prediction of behavior by attitudes and the operationalization of UP.
