Clinical guidelines recommend that physicians educate patients about illnesses and antibiotics to eliminate inappropriate preferences for antibiotics. We expected that information provision about illnesses and antibiotics would reduce but not eliminate inappropriate preferences for antibiotics and that cognitive biases could explain why some people resist the effect of information provision. In 2 experiments, participants (n₁ = 424; n₂ = 434) either received incomplete information (about the viral etiology of their infection) or complete information (about viral etiology and the ineffectiveness and harms of taking antibiotics), before deciding to rest or take antibiotics. Those in the complete information conditions responded to items on 4 biases action bias, social norm, source discrediting, and information neglect. In 2 follow-up experiments (n₁ = 150; n₂ = 732), we aimed to counteract the action bias by reframing the perception of the resting option as an action. Complete information provision reduced but did not eliminate inappropriate preferences for antibiotics. Around 10% of people wanted antibiotics even when informed they are harmful and offer no benefit and even when the alternative option (i.e., rest) was framed as an active treatment option. Results suggest an action bias underpins this preference but appears challenging to counteract.

Numeracy, which refers to individual differences in the ability to understand numerical concepts and work with probabilities, has been linked to health-related decision-making and medical and financial outcomes. Whether affective influences impact numeracy has not been experimentally assessed, although research has shown that emotions impact judgments and decision-making. Stress is one commonly experienced affective influence that could impact numeracy. We examined whether objective and subjective numeracy were influenced by stress induced from anticipating giving a speech in a laboratory setting. We also examined the association of self-reported math anxiety, or apprehension pertaining to mathematics, with objective and subjective numeracy. Two experiments were conducted; the second was a direct replication. Undergraduate students (Experiment 1, n = 99; Experiment 2, n = 139) were randomly assigned to one of two conditions a stress induction or a neutral condition. Whereas neither objective nor subjective numeracy significantly differed across conditions, math anxiety was a consistent predictor of objective and subjective numeracy. Math anxiety and baseline perceived stress did not consistently moderate any effects. These findings have implications for health care, educational, and financial contexts in which people must make decisions that involve complex numbers. https://www.selleckchem.com/products/4-phenylbutyric-acid-4-pba-.html (PsycInfo Database Record (c) 2020 APA, all rights reserved).Efficiently communicating information on vaccination is crucial to maintaining a high level of immunization coverage, but it implies finding the right content for the right audience. Provaccination individuals, who represent the majority of the population, and who have been neglected in the literature, could play an important role relaying provaccination messages through informal discussions, if only these messages are (a) found plausible, (b) remembered, and (c) shared. We conducted 7 experiments on 2,761 provaccination online participants (United States and United Kingdom), testing whether the valence of a statement (positive or negative) and its rhetorical orientation (pro- or antivaccine) affected these 3 steps. Participants deemed more plausible, were more willing to transmit (and actually transmitted more), but did not remember positively framed statements better. Provaccination rhetorical orientation had little or no effect. Overall, the framing effects observed were dramatic one framing made participants very eager to transmit a statement, while another made them reluctant to transmit it at all. The framing effects also influenced vaccination attitudes, with participants exposed to positively framed statements reporting more positive attitudes toward vaccination. Since messages have to be framed one way or the other, the framing effects demonstrated here should be considered when designing public health messages.

It is possible that military sexual assault (MSA) is associated with heightened psychological distress compared to adult sexual assault that occurs pre- or postmilitary service due to the nature of the military setting. Veterans and service members (N = 3,114; 19.6% women) who participated in the Post-Deployment Mental Health Study completed self-report measures of sexual assault history, symptoms of posttraumatic stress disorder (PTSD), symptoms of depression, hazardous alcohol use, drug use, and suicidal ideation. Women who reported a history of MSA endorsed higher levels of all types of psychological distress than women who did not experience adult sexual assault. Women who reported a history of MSA also endorsed higher levels of PTSD and depression symptoms than women who experienced pre- or postmilitary adult sexual assault. Men who reported a history of adult sexual assault, regardless of setting, reported higher levels of PTSD and depression symptoms than individuals who did not experience adult sexual assault. MSA was associated with higher psychological distress than pre- or postmilitary adult sexual assault among women. Among men, distress associated with MSA was comparable to sexual assault outside the military. Women may face unique challenges when they experience sexual assault in the military, and men may face additional stigma (compared to women) when they experience sexual assault, regardless of setting.

Past research has found that more diverse emotional experiences, both positive and negative, are related to better mental and physical health outcomes. The present research aimed to test the relationship between positive and negative emodiversity across the span of 8 days with measures of health and well-being using 2 samples of the Midlife in the United States study (http//midus.wisc.edu/). Participants (N = 2,788) reported emotional states (14 negative, 13 positive) once each day for 8 days. Emodiversity scores were computed for each day using an adaptation of Shannon's biodiversity index and averaged across the days. All models included average affect and demographic covariates. Greater positive emodiversity was associated with fewer symptoms of depression and anxiety and fewer physical health symptoms but was not related to eudaimonic well-being nor cognitive functioning.
