The objective of this study is to investigate the role of attitude towards the activity targeted by the technology in a perceived risk-motivation information technology adoption model. A theoretical model was developed and tested empirically with 170 respondents from the UK for the case of using cell phones in smoking cessation interventions. Results show attitude towards smoking had a negative...

As the driver is the information recipient and primary decision maker in the driving process, this research aims to investigate a driver's risk awareness to assess a driver's safety. We developed a scale for assessing a driver's risk awareness, which consists of four scales: Risk Attitude (48 items), Risk Perception (22 items) and Risk Behavior (27 items) scale, and the Sensation Seeking Scale ...

Most decision models published in the medical literature take a risk-neutral perspective. Under risk neutrality, the utility of a gamble is equivalent to its expected value and the marginal utility of living a given unit of time is the same regardless of when it occurs. Most patients, however, are not risk-neutral. Not only does risk aversion affect decision analyses when tradeoffs between shor...

OBJECTIVE To evaluate HIV/AIDS vulnerability by risk factors in women at social risk. METHODS Study conducted in a sample of 178 female homemakers (n=101) and female health providers (n=77) from Antofagasta, Chile, in 20062007. Homemakers were considered at social risk. HIV vulnerability was estimated through a 21-item instrument comprising three domains: gender roles; relationship with the p...

The dental profession has a high risk of hepatitis B virus (HBV) contamination and can play a crucial role in controlling HBV cross-contamination. In this cross-sectional study we used unique methods to assess Tehran dentists' knowledge, attitude and behaviour regarding HBV. Two simulated HBV-positive patients visited 300 general/specialist dentists in their offices and recorded dentists' willi...

This paper explains physicians’ acceptance, in terms of usage intentions, of one of the most relevant eHealth services or applications: Electronic Health Care Records (EHCR). For this purpose, the original structure of the Technology Acceptance Model (Davis et al. 1989: 985), which included perceived usefulness, perceived ease of use, attitude, and usage intention, is extended with trust and ri...

The purpose of this research is to seek the best (highest performing) risk profiles of agents who successively choose among risky prospects. An agent’s risk profile is his attitude to perceived risk, which can vary from risk preferring to risk neutral (an expected-value decision maker) to risk averse, or even a dual-risk attitude. We use the Genetic Algorithm to search in the complex stochastic...

In this study, respondents from the P.R.C., U.S.A., Germany, and Poland were found to differ in risk preference, as measured by buying prices for risky financial options. Chinese respondents were significantly less risk-averse in their pricing than Americans when risk preference was assessed in the traditional expected-utility framework. However, these apparent differences in risk preference we...

Risk perception is a phenomenon in search of an explanation. Several approaches are discussed in this paper. Technical risk estimates are sometimes a potent factor in accounting for perceived risk, but in many important applications it is not. Heuristics and biases, mainly availability, account for only a minor portion of risk perception, and media contents have not been clearly implicated in r...
