“…Younger adults in comparison to middle-aged and older adults perceive themselves as being less vulnerable for diseases. Moreover, with increasing age, risk perception appears to become a more important motivational drive even though the actual health status may not have changed (Renner, Knoll, & Schwarzer, 2000;Renner, Spivak, Kwon, & Schwarzer, 2007;. This suggests that middle-aged and older adults might regard physical activity as an explicit health behavior, whereas younger adults consider it as a lifestyle behavior driven by social influence and daily leisure habits.…”

Abstract. At a broad level, the Konstanz Health Psychology research group aims at understanding the judgment and decision making processes underlying health-relevant behaviors. Towards this goal, several more specific research agendas are addressed. A primary aim is to understand the transition from knowing about risks to personally feeling at risk. In particular, we study the reception of relevant personalised health feedback such as feedback on cholesterol levels or blood pressure. Contrary to the dominant models of biased reasoning, our results on feedback reception suggest that people respond adaptively to health risk feedback. Furthermore, we study changes in the perception of health risk across time and their associated effects on the onset, maintenance, and cessation of health-relevant behaviors. In current research, we try to utilize methods from affective neuroscience for assessing affective and intuitive processes relevant to personal feelings of risk. These efforts are motivated by the broader goal of developing theoretical frameworks that can be applied across a range of behavioral domains. Key words: risk perception, health behavior change, reception of feedback The health psychology research group at the University of Konstanz is interested in the judgment and decisionmaking processes underlying health-relevant behaviors. A main goal is to understand the transition from knowing about risks to personally feeling at risk. Furthermore, the perception of health risks is a dynamic phenomenon. Thus, we aim to understand dynamic changes in risk perception and their associated effects on the onset, maintenance, and cessation of health-relevant behaviors. These efforts are motivated by the broader goal of developing theoretical frameworks that can be applied across a range of behavi oral domains.

Dietary Planning as a Mediator of the Intention–Behavior Relation: An Experimental‐Causal‐Chain Design

et al. 2008

Health behavior change is seen as a self-regulatory process that consists of a motivation phase of goal setting and a volition phase of goal pursuit. Previous studies suggest that the intention-behavior association is mediated by planning. However, evidence is based on observational studies rather than on experimental designs. To validate the causal assumptions, an experimental-causal-chain design was employed. Study 1 ( n = 145) examined whether changing dietary intentions by a motivational intervention engenders changes in planning activities 1 month later. Study 2 ( n = 115) examined, in a different sample, whether a volitional planning intervention engenders changes in dietary behavior 1 month later. In both studies, repeated measures ANOVAs revealed a significant Time × Condition interaction. Changes in intention mediated the effects of the motivational intervention on planning activities (Study 1). Changes in planning mediated the effect of a planning intervention on dietary behavior (Study 2). Previous observational findings on planning as a mediator in the intention-behavior association were supported by the two experiments. The findings might help to identify points of intervention in the process underlying health behavior change.Le changement de comportement au plan de la santé est considéré comme un processus d'auto-régulation qui se compose d'une phase de motivation (fixation des buts) et d'une phase de volition (poursuite des buts). Des études précédentes suggèrent que le passage de l'intention au comportement est médiatisé par la planification. Ces résultats sont obtenus par voie d'observations plutôt que par expérimentations. Pour valider les hypothèses de causalité, un modèle de chaîne-causale-expérimentale a été employé.

Individual Risk Perception and Flood Mitigation: An Empirical Study of Protective Actions in Australia

The Australian government has increasingly expected that individuals collaborate with public efforts to reduce hazard risks by taking some action themselves. This expectation, however, has failed to consider the complexity of the decision-making process at the household level.Individual decision making is rather complex as it involves a wide range of factors that should be taken into account before the government can assess to what extent individuals at risk can effectively contribute to the reduction of hazard risks. This is where a theoretical framework makes a contribution to this thesis by guiding data collection and analysis. Thus this thesis resorts to a comprehensive socio-psychological theory to generate empirical data on the different factors affecting decision making under uncertainty.The testing of this comprehensive theoretical framework called Protection Motivation Theory focuses on the explanatory variables of risk perception ('threat appraisal') and coping measures ('coping appraisal'). Threat appraisal factors have to do with the perception of hazard risks and coping appraisal variables measure the perceived ability of an individual to take action. The novelties of this study are i) the application of this theoretical framework, which has already been tested in order countries, for the first time in Australia, more specifically among householders living in flood-prone locations in Southeast Queensland; ii) a dataset featuring significant variability in terms of vulnerability and exposure levels of the population at risk; iii) the assessment of how heuristics and biases affect decision making under uncertainty; and iv) qualitative data to unpack non-intuitive associations and understand the role that the nature of threats and protective actions play in the decisions of householders to take protective actions. An interesting finding from previous studies is that coping factors are better predictors for protective actions than risk perception. This thesis then will verify whether this association is also observed in the Australian context. However, emerging from this study, is the argument that individuals at risk living in this region make decisions which do factor in their hazard risk perceptions and their perceived capacity to take action; however, this decision-making process also take into account the vulnerability conditions of the population at risk. Also, qualitative data suggest that exposure to hazard risks shaped by the nature of the threat and the characteristics of the protective action also play a role in the decision of householders to take preventive measures that reduce or eliminate flood damage. The findings on how these conditions and circumstances influence decisions made under uncertain scenarios are the main contribution of this thesis to the literature. 3This contribution, however, is not only relevant within the academic community. If Australian authorities are to enhance the resilience of communities at risk to potential damage caused by hazards, it needs first to ha...
