BARNOY S, OFRA L and BAR‐TAL Y. Nursing Inquiry 2012; 19: 128–133 [Epub ahead of print]What makes patients perceive their health care worker as an epistemic authority?Health care workers’ (HCW) perceived epistemic authority (EA) may have an effect on patient decision‐making and compliance. The present study investigated the hypotheses that higher EA is attributed to staff perceived to be experts; to physicians rather than nurses; to HCWs who recommend taking a test more than to the ones who make no recommendation. (...) The study was based on a factorial 2 × 2 × 2 within‐between subjects design. The questionnaire presented four scenarios, each illustrating a HCW presenting information on a devastating genetic disease. The three variables manipulated were: HCW expertise, HCW role, and making a recommendation or not. After each scenario participants were asked questions about the EA they attributed to the HCW in the scenario. The results show main effects for perceived expertise and recommendation/no recommendation on the level of EA attributed. Expert nurses were judged to have the same high EA as expert physicians. But expert physicians who recommended taking a test were judged as having significantly higher EA than expert physicians who made no recommendation. Among nurses who made no recommendation, expert nurses were evaluated as having significantly higher EA than novices. Since expert nurses were perceived to have equal expertise as expert physicians, it follows that information given by both nurses and physicians can reduce patient uncertainty. (shrink)

Influenza is a major cause of morbidity and mortality. Although vaccination is an efficient means of prevention, low rates of vaccination are reported periodically. The study aimed to examine factors affecting acceptance of nurses' recommendations to take or avoid influenza vaccination. Study design was quasi‐experimental with a 2 × 2 between subjects design: two variables were manipulated and two were not. The research variables were expertise (of nurses and respondents), type of recommendation (to vaccinate or not) and respondents' a‐priori intention (...) to vaccinate. Data were collected from 374 respondents. The study was scenario based, differing in nurse expertise and type of recommendation. After each scenario, the respondents were requested to indicate their a‐priori intention to vaccinate and to complete questionnaires on epistemic authority (EA) attributed to the nurse, and of self‐epistemic authority (SEA). There is a general tendency to avoid vaccination. Intention to vaccinate correlated positively with nurse recommendations, respondent a‐priori intention and nurse expertise. A significant three‐way interaction between respondents' SEA, nurse recommendations and nurse expertise was found. The nurse's recommendation has the strongest effect when the nurse is an expert and the respondent perceives him/herself as having high self‐EA. The results highlight the importance of patients' sense of knowledge for assuring their co‐operation and compliance with medical recommendations. (shrink)

Need for closure and cognitive structuring among younger and older adults The paper reported two correlational studies. The aim of the Study 1 was to examine the hypothesis that age moderates the relationship between need for closure and cognitive structuring. Results of the study revealed that aging with increased need for closure was associated with better recognition of irrelevant information than schema-relevant items, in testing hypotheses about the target person. These findings are interpreted as demonstrating the age-associated failure of cognitive (...) abilities, reducing tendency to behave according to the level of epistemic motivation. The results of Study 2 demonstrated that older participants are characterized by higher NFC but by lower EFNC than young participants. These results are consistent with the conclusion that the negative relationships between NFC and cognitive structuring demonstrated by the older participants in Study 1 can be attributed to their lower level of EFNC.

The main goal of our study was to investigate the role of insight into one’s own biases in the process of hypothesis validation in accordance to the two fundamental social perception domains on the example of confirmation bias. The study was conducted on a group of 593 participants with the use of a confirmation bias procedure, a free recall procedure and the Metacognitive Self scale. We manipulated with the domain and the value of information given to the respondents. We suspected (...) that individuals with a high metacognitive self, in opposition to low metacognitive self ones, would not process the given information according to the two fundamental social perception domains. The results verified the existence of an interaction effect of the metacognitive self and the domain of the information given about a perceived person on the susceptibility to follow the confirmation bias. Contrary to the low metacognitive self individuals, who show a higher tendency for the confirmation bias within the competence than the community domain, persons with a high insight into their own biases express the same level of confirmation bias in no respect to the domain of the information. The value of the information has no significant influence. (shrink)
