Based on construal level theory, one would expect that consumers cognitively represent the individual and collective outcomes of an allocation policy at different levels of abstraction and that they evaluate allocation policies more positively when there is congruency between the cognitive representation of the policy’s focal outcome and the spatial and temporal distance inherently present in the policy’s decision context (e.g., allocation decisions on a future policy). However, we hypothesize that this congruency effect can be overruled by a high vested interest mindset that is activated by an individual’s recent personal experience with a health care service provider. Since a high vested interest mindset increases the relevance of the allocation policy implementation for the individual because s/he perceives strong personal consequences, we propose that for consumers with recent experience the evaluation of an allocation policy that focuses on individual outcomes is higher than that of a policy that focuses on collective outcomes irrespective of the spatial and temporal distance in the decision context. Results of a hypothetical experiment among a representative sample of the general population confirm the congruency effects in the new domain of health care service allocation policies, and provide support for the proposed overruling effect of the activation of a high vested interest mindset by recent personal experience on spatial and temporal distance. http://repub.eur.nl/res/pub/37794/ 2012-06-01T00:00:00Z Online retailers significantly benefit when consumers use interactive decision aids (IDAs). In this study, we investigate how to best design messages that promote IDA use. Using an extended message framing perspective, we propose that messages about consumers' traditional action (searching) increase usage intentions more than messages about the new action (IDA use). Results from two experiments confirm that this holds across both high and low involvement categories and in particular when the traditional action frame is combined with a loss outcome. We also demonstrate that familiarity with the message's focal action mediates this effect. http://repub.eur.nl/res/pub/25862/ 2011-04-01T00:00:00Z Interactive decision aids (IDAs) typically use concrete, feature-based approaches to interact with consumers. Recently, however, interaction designs that focus on communicating abstract consumer needs have been suggested as a promising alternative. This paper investigates how temporal distance moderates the effectiveness of these two competing IDA communication designs by its effect on consumers' mental representation of the product decision problem. Temporal distance is inherently connected to IDAs in two ways. Congruency between consumption timing (immediate versus distant) and IDA communication design (concrete versus abstract, respectively) increases the likelihood to accept the IDA's advice. This effect is also achieved by congruency between IDA process timing (immediate versus delayed delivery of recommendations) and IDA communication design (concrete versus abstract, respectively). We further show that this process is mediated by the perceived transparency of the IDA process. Managers and researchers need to take into account the importance of congruency between the user and the interface through which companies interact with their users and can further optimize IDAs so that they better match consumers' mental representations. http://repub.eur.nl/res/pub/23453/ 2011-03-01T00:00:00Z Interactive decision aids (IDAs) typically use concrete, feature–based approaches to interact with consumers.

This article investigates how temporal distance moderates the effectiveness of these two competing IDA communication designs by its effect on consumers’ mental representation of the product decision problem. Temporal distance is inherently connected to IDAs in two ways. Congruency between consumption timing (immediate vs. distant) and IDA communication design (concrete vs. abstract, respectively) increases the likelihood to accept the IDA’s advice. This effect is also achieved by congruency between IDA process timing (immediate vs. delayed delivery of recommendations) and IDA communication design (concrete vs. abstract, respectively).
