Factors Influencing Level of Stress During the Nursing Home Decision Process

This investigation examined whether characteristics of elders and their caregivers and facets of the nursing home decision-making context were associated with recalled levels of stress during nursing home decision-making. Employing a conceptual framework based upon the literature on caregiver stress and nursing home decision-making, we considered a number of factors that might influence sponsors' stress as decisions were being made about nursing home placements. We examined data from telephone interviews with a sample of 142 sponsors (responsible parties) of first-time, recently admitted nursing home residents. Higher levels of reported stress were directly associated with more factors triggering the decision to admit, higher levels of competing demands, and limited time. Employment was indirectly related to higher stress through its impact on demands. Hospitalization and being the spouse or an adult child of the resident were indirectly related to stress because they were associated with limited available time. The results offer some insights into the types of individuals who may be vulnerable to higher levels of stress and the kinds of interventions that might avert high stress in the nursing home decision process.     

Investigating the roots of the favourite–longshot bias: an analysis of decision making by supply‐ and demand‐side agents in parallel betting markets

This paper offers new insights into the behavioural origins of the ‘favourite–longshot’ bias — an established feature of betting markets, whereby longshots win less often than the subjective probabilities imply and favourites more often. A number of alternative explanations has been offered for this phenomenon but the main debate focuses on whether it is caused by the behaviour of those supplying betting markets (bookmakers) or of the demand‐side agents in these markets (bettors) . This study analyses a new data source which offers detailed information for a large sample of recent UK horseraces on decision‐making behaviour within the parimutuel and the parallel bookmaker‐based betting markets. The results offer strong evidence for the existence of the ‘favourite–longshot’ bias in bookmaker‐based markets, with a corresponding absence of such an effect in the parimutuel case. These results offer support for the view that the origins of the ‘favourite–longshot’ bias lie principally in the decisions of bookmakers rather than in the decisions of bettors.

Power Relations and Group Aggregation in the Multiplicative AHP and SMART

The relative power of the members in a group of decision makers can be incorporated in the multiplicative AHP via power coefficients in the logarithmic least squares whereby we analyse the pairwise comparison matrices. When each decision maker judges every pair of alternatives under each of the criteria, aggregation over the criteria and over the decision makers proceeds via a sequence of geometric-mean calculations which can be carried out in any order, at least with predetermined criterion weights and power coefficients. Hence, since we preserve the rank order of the alternatives, we avoid a deficiency of the original AHP. We also consider SMART, an additive method which is logarithmically related to the multiplicative AHP so that power relations can easily be incorporated in it. Finally, in order to illustrate the proposed model, we analyse a generalized version of the well-known example of Belton and Gear as well as the power relations between member countries of the European Community. © 1997 by John Wiley & Sons, Ltd.

The decision to check in multialternative choices and limited sensitivity to default

Given the rapid proliferation of smartphone applications and data aggregation websites, in many situations people can use decision aids to guide their choices. For example, they may consider whether to use a navigation device to check the fastest route or whether to use a price comparison website to find the cheapest deal. In what circumstances will subjects use a costly comparison decision aid (which I refer to as “checking”) to choose for them? In six studies, I investigate the impact of the number of available alternatives and checking's attractiveness on the decision to check. While at first increasing the attractiveness of checking led to higher checking rates, a further increase in the number of available alternatives (and thus checking's attractiveness) did not increase the checking rate. Surprisingly, even when checking had a 40% higher expected value compared with not checking, the observed checking rate was below 45%, contrary to risk and ambiguity aversion predictions. Furthermore, labeling the checking alternative as the default had no impact on its choice rate. I find large individual differences in decisions to check. Surprisingly, subjects' initial decisions had high predictive power over their subsequent checking rates, even after 100 trials with full feedback. I propose two simple learning models that capture well the aggregated results.     

Asymmetric cost and benefit perceptions in willingness-to-donate decisions

Charitable giving entails the act of foregoing personal resources in order to improve the conditions of other people. In the present paper, we systematically examine two dimensions integral to donation decisions that have thus far received relatively little attention but can explain charitable behavior rather well: the perceptions of cost for the donor and benefit for the recipients. In line with current theories in judgment and decision making, we hypothesize that people weigh these dimensions subjectively and perceive them asymmetrically, consistent with prospect theory. Costs for the donor are typically perceived as losses, whereas benefits for recipients are perceived as gains. In four studies, we presented several scenarios to participants in which both donation amounts (costs) and number of lives helped (benefits) were manipulated while keeping the ratio of costs and benefits constant. Results from Studies 1 and 2 showed that willingness to help decreased as donation amounts and number of lives helped increased. Additionally, Studies 3 and 4 provide evidence for a solution to reduce the asymmetry and increase donation amounts as the number of lives at risk increases.     

Decreasing influence of arbitrarily applicable verbal relations of recreational gamblers: A randomized controlled trial

Twenty‐one recreational gamblers were randomly assigned to two groups; one group was exposed to a conditional discrimination relational training task to bias choice allocation to a black machine presented concurrently with a red machine, and the other group underwent the same relational training task immediately followed by a defusion procedure, designed to expand upon the relations developed in the initial relational task. Both groups completed a simulated slot‐machine task before and after the relational training task, with or without the defusion procedure. Results showed that 9 of 11 participants in the relational training only group showed an increased bias toward the black machine, compared to only 4 of 10 in the relational training plus defusion group; this latter group also showed greater matched responding. Results suggest that expanding verbal–relational networks may reduce the influence of any single verbal relation on gambling choice behavior.     

Attachment and behavioral addictions in adolescents: The mediating and moderating role of coping strategies

Gambling, video gaming, and Internet use are typically included as everyday activities that could potentially become behavioral addictions. There is growing evidence that views non‐substance related addictions as coping mechanisms, and considers that attachment styles are likely to play a pivotal role on the development of such addictions, especially on young people. Therefore, the present study aimed to: (1) explore the association between attachment, coping, and behavioral addictions (i.e., gambling disorder, video game addiction, and problematic Internet use); and (2) to analyze the mediating/moderating effect that coping has in the relationship of attachment and these behavioral addictions. A sample consisting of 472 students from secondary education (Mean age = 15.6; SD = 1.33; 51.6% females) was recruited. The findings showed a negative association between attachment and behavioral addictions. Most coping strategies were found to be associated with attachment styles, except for self‐critique and emotional avoidance. In particular, problem avoidance was significantly correlated to all behavioral addictions. In addition, self‐blame and problem solving were significantly correlated to video game addiction and problematic Internet use. Finally, coping was found to act as a mediator and moderator between attachment and video game addiction and problematic Internet use.     

The gap between medical and monetary choices under risk persists in decisions for others

Decisions under risk in the medical domain have been found to systematically diverge from decisions in the monetary domain. When making choices between monetary options, people commonly rely on a decision strategy that trades off outcomes with their probabilities; when making choices between medical options, people tend to neglect probability information. In two experimental studies, we tested to what extent differences between medical and monetary decisions also emerge when the decision outcomes affect another person. Using a risky choice paradigm for medical and monetary decisions, we compared hypothetical decisions that participants made for themselves to decisions for a socially distant other (Study 1) and to recommendations as financial advisor or doctor (Study 2). In addition, we examined people's information search in a condition in which information about payoff distributions had to be learned from experiential sampling. Formal modeling and analyses of search behavior revealed a similarly pronounced gap between medical and monetary decisions in decisions for others as in decisions for oneself. Our results suggest that when making medical decisions, people try to avoid the worst outcome while neglecting its probability—even when the outcomes affect others rather than themselves.     

Jeux de hasard et d’argent en ligne : quelles spécificités en matière de réduction des risques ?

Initially conceived as an alternative to abstinence-based approaches, the initial goal of harm-reduction was to reduce the health consequences of drug use. Applied to all addictive behaviors (with or without use), it aims to reduce the individual and social problems generated by addiction without condemning the behavior. Harm-minimisation remained very poor in the gambling field. However, the legalization of online gambling in France and their specific characteristics, update the need to develop this field, which is still a new and relatively uncommon part of harm-reduction. The aim of this article is to draw up an inventory of existing knowledge, whether it has been tested empirically or not, in an ecological environment or in a laboratory situation, as regards tools allowing the player to remain in control of his gambling behavior. A reflection on future research and other possible tools is envisaged.
