This study examines the impact of a reasonable time limit on the effective usage of a computerized decision aid. Using current decision making models, a theoretical argument about decision aid usage is developed. This argument is then investigated via two lab experiments. The first experiment determines a reasonable time limit for the task used in the study. The second experiment investigates u...

BACKGROUND Previous research has examined the impact of patient narratives on treatment choices, but to our knowledge, no study has examined the effect of narratives on information search. Further, no research has considered the relative impact of their format (text vs video) on health care decisions in a single study. OBJECTIVE Our goal was to examine the impact of video and text-based narra...

As computer-based decision aids become more widely available – both online and on the office desktop, better insights are needed into how their design features influence people’s willingness to use them. This research hypothesizes and shows that the extent to which decision aids require decision makers to explicitly confront difficult tradeoffs increases their decision anxiety, undermining thei...

OBJECTIVE To assess the efficacy of an interactive smoking cessation decision-aid application (pp) compared with a smoking cessation static information app on continuous abstinence. DESIGN Automated double-blind randomised controlled trial with 6 months follow-up (2014-2015). SETTING Smartphone-based. PARTICIPANTS 684 participants (daily smokers of cigarettes, 18 years old or over) recrui...

-This paper provides a simple probability analysis of the usefulness of decision aids that generate fallible advice . The main results are as fol­ lows. The usefulness of a decision aid depends heavily on the ability of the user to identify contexts in which the aid (or user unaided) is likely to be incorrect. Without this ability, attending to (i.e., consider, but not always ac­ cept) the advi...

The diviz software is a tool for designing, executing and sharing Multiple Criteria Decision Aid (MCDA) techniques. The target user community of diviz reaches from researchers who require to construct algorithmic workflows of elementary MCDA components to teachers who need to present MCDA methods and let their students experiment them. Besides, one of the principal features of diviz is to ease ...

BACKGROUND The decision to have lung transplantation as treatment for end-stage lung disease from cystic fibrosis (CF) has benefits and serious risks. Although patient decision aids are effective interventions for helping patients reach a quality decision, little is known about implementing them in clinical practice. Our study evaluated a sustainable approach for implementing a patient decision...

OBJECTIVE Poor adherence to therapy, perhaps related to unaddressed patient preferences, limits the effectiveness of osteoporosis treatment in at-risk women. A parallel patient-level randomized trial in primary care practices was performed. METHODS Eligible postmenopausal women with bone mineral density T-scores less than -1.0 and not receiving bisphosphonate therapy were included. In additio...

In online shopping scenarios, it can be difficult for consumers to process the vast amounts of information available and to make satisfactory buying decisions. Interactive decision aids are a potential solution to this problem. However, decision aids that filter a very large set of alternatives based on initial preferences may eliminate potentially valuable alternatives early in the decision pr...
