OBJECTIVE The study examined the role of anticipated regret in human papillomavirus (HPV) vaccination decisions as well as potential antecedents of anticipated regret. METHOD In 2007, we interviewed 889 caregivers for girls aged 10-18 in areas of North Carolina with high rates of cervical cancer. The survey assessed vaccination regret (anticipated regret if daughter became more sexually activ...

BACKGROUND We sought to estimate the extent of decision regret among primary care patients and identify risk factors associated with regret. METHODS Secondary analysis of an observational descriptive study conducted in two Canadian provinces. Unique patient-physician dyads were recruited from 17 primary care clinics and data on patient, physician and consultation characteristics were collecte...

To cope with changing environments, recent developments in online learning have introduced the concepts of adaptive regret and dynamic regret independently. In this paper, we illustrate an intrinsic connection between these two concepts by showing that the dynamic regret can be expressed in terms of the adaptive regret and the functional variation. This observation implies that strongly adaptiv...

The minmax regret problem for combinatorial optimization under uncertainty can be viewed as a zero-sum game played between an optimizing player and an adversary, where the optimizing player selects a solution and the adversary selects costs with the intention of maximizing the regret of the player. Existing minmax regret models consider only deterministic solutions/strategies, and minmax regret...

Patients who choose elective procedures while in a hot state and end up with a bad outcome may be at particular risk for regret due to commission bias. Some researchers believe that the relationship of regret to either action or inertia mus...

In a stock market experiment, we examine how regret avoidance influences the decision to sell an asset while its price changes over time. Participants know beforehand whether they will observe future prices after or not. Without prices, participants are affected only by about previously observed high (past regret), but when available, also avoid expected after-sale (future regret). Moreover, as...

The article considers three theses about postabortion regret which seek to illustrate its pertinence to reasoning about abortion, and which are often deployed, either explicitly or implicitly, to dissuade women out of that reproductive choice. The first is that postabortion regret renders an abortion morally unjustified. The second is that that a relatively high incidence of postabortion regret...

When a …rm introduces a product with new features, some consumers may …nd it di¢ cult to assess their valuations for these new attributes. Their purchase decisions made under such uncertainty may lead to post-purchase regret. It has been experimentally shown that consumers anticipate their potential post-purchase regret in the future and make their current choices to mitigate or minimize it. Th...

Decisions are powerfully affected by anticipated regret, and people anticipate feeling more regret when they lose by a narrow margin than when they lose by a wide margin. But research suggests that people are remarkably good at avoiding self-blame, and hence they may be better at avoiding regret than they realize. Four studies measured people's anticipations and experiences of regret and self-b...

In this study we explored the prevalence of regret following uncommitted sexual encounters (i.e., casual sex that occurs with someone once and only once or with someone known for less than 24 hours) among 138 female and 62 male Canadian university students, who were approximately 21 years of age. The majority of participants self-reported that they had experienced feelings of regret after an un...
