This paper reports student (n = 180) feedback on the role-play teaching methodology used in behavioural sciences teaching at The School of Dentistry in Birmingham (UK). The feedback received on this well-established (since 1995) educational programme was collected via questionnaire (100% response rate), requiring Likert scale and free text responses. Generally students reported that they had enjoyed and valued the session. Over two-thirds (69.7%) of students rated the role-players as 'very real' and over three-quarters (78.9%) rated their feedback as 'very fair'. The data collected from this study will inform future curriculum development. Student feedback was very positive and demonstrated that the cohort (86% of all students studying in years 1, 2 and 3) found the use of professional role-players involved in behavioural sciences teaching to be both acceptable and valuable. 相似文献

Abstract It is a fundamental assumption in nursing theory that it is important for nurses to understand how patients think about themselves and the contexts they are in. According to modern theories of hermeneutics, a nurse and a patient must share the same concepts in order to communicate beliefs with the same content. But nurses and patients seldom understand medical concepts in exactly the same way, so how can this communicative aim be achieved in interaction involving medical concepts? The article uses a theory of concepts from recent cognitive science and philosophy of mind to argue that nurses and patients can share medical concepts despite the diversity of understanding. According to this theory, two persons who understand medical language in different ways will nevertheless possess the same medical concepts if they agree about the normative standards for the applications of the concepts. This entails that nurses and patients normally share medical concepts even though patients’ conceptions of disease and illness are formed in idiosyncratic ways by their social and cultural contexts. Several practical implications of this argument are discussed and linked to case studies. One especially important point is that nurses should seek to make patients feel comfortable with deferring to a medical understanding. In many cases, an adequate understanding of patients presupposes that nurses manage to do this. Another implication is that deference‐willingness to normative meaning is not equivalent to the actual application of concepts. Deference‐willingness should rather be thought of as a pre‐communicative attitude that it is possible for patients who are not fully able to communicate to possess. What is important is that nurses and patients have the intention of conforming to the same meaning. 相似文献

After 14 years of rising death rates due to unintentional injuries in the U.S., it is time to ask how safety messages can be redesigned to have a greater impact on risky behavior. To this end, many researchers have called for a new, narrative approach to prevention messages—based on persuasive stories about people who have suffered injuries and illnesses in the past. Still, there is scant evidence that story-based communications are more effective than equivalent non-narrative messages at changing actual (rather than self-reported) safety and health behavior. Our research examined the impact of injury stories on actual safety behavior in a controlled experimental setting at a US university. Teams of participants assembled a product (a child's swing) using written instructions. The instructions contained safety messages targeting assembly mistakes that have been linked to serious injuries in children who play on swings. Participant teams were randomly assigned to three conditions: assembly instructions containing story-based safety messages, instructions with concrete (but non-anecdotal) safety messages, and instructions with traditional abstract safety messages. After adjustment for covariates, story-based messages resulted in a 19 percent improvement in safety behavior, compared with non-narrative communications. Importantly, injury stories did not create undue fear of the message object, demonstrating that brief anecdotes about accident victims can convince people to take reasonable precautions without creating unwarranted alarm about risks. 相似文献

PurposeAlthough an adult model of patient-provider mutual exchange of information has been proposed, there is no guiding model for adolescents or measurement methodology. Our purpose was to develop a new scale of patient-provider interaction for adolescents accessing reproductive health care and at risk for sexually transmitted diseases (STDs) and human immunodeficiency virus (HIV), and assess the reliability and validity of the scale.MethodsThe Adolescent Patient-Provider Interaction Scale (APPIS) was developed from the Roter and Hall theory of doctor-patient relationships, previously validated adolescent satisfaction and communication scales, and focus group and individual elicitation interviews. To assess construct validity, the new nine-item APPIS was compared with the satisfaction scale used by the Young Adult Health Care Survey (YAHCS), and Kahn’s Provider Communication Scale. Pearson correlation coefficients were used to examine convergence across scales, and factor analysis of the APPIS was performed.ResultsThe study recruited 192 African American girls aged 17.9 ± 1.7 years (range 15–21 years) from three sites: a county STD clinic (n = 51), urban adolescent clinic (n = 99), and a family planning clinic (n = 42). Most participants (85%) rated their overall health care highly (≥ 7 on a 10-point scale); 49% felt that both the provider and patient were “in charge” of the visit, and 88% “strongly agreed” or “agreed” that there was an equal “exchange of information” during the visit. The APPIS showed good internal consistency (Cronbach alpha = .75), and moderate convergence with the six-item YAHCS scale (r = .57, p < .001) and seven-item Kahn scale (r = .48, p < .001). Three factors emerged from exploratory factor analyses, supporting our conceptualization of patient-provider interaction as being multi-dimensional.ConclusionsA new theory-based scale of adolescent patient-provider interaction compares favorably with previous scales of health care satisfaction and communication. The new APPIS may be useful for evaluating approaches to improve health care outcomes for adolescents at-risk for STDs and HIV. 相似文献

This study investigated the temporal evolution in the discrimination of the newborn's crying by the mother, from the first to the eighth day after birth. The sample included twenty human mothers who had had an uneventful pregnancy, labour and delivery. They were asked to identify the spontaneous cries of their newborn babies from tape-recorded cries containing cries from their own newborn and from three other newborns. On the first day, the percentage of correct answers was 48#pc, then 81 #pc on the eighth day. Two acoustic features that may underlie this discrimination were analyzed: the maximum Fo values and the average number of cry bursts per second. On the seventh day, these two acoustic variables and the discrimination abilities significantly correlate. 相似文献

Summary: The Internet contains a vast amount of medically relevant information. In order to access this information, however, many networks require one to master applications written in UNIX, an operating system considered by many not to be user friendly. Although these tools may be available on the campus, it is difficult to teach their use unless there is some immediate benefit to the already busy user. From that standpoint, it is important for instructors to realize that common UNIX applications can be utilized as classroom tools to significantly enhance the learning experience by facilitating teacher/student communication. Also, whilst the student enjoys greater communication with the instructor (and with other students) he/she is also becoming adept at using information management tools. 相似文献

Communication between an occupational physician and other medical practitioners--an audit 总被引:4,自引:0,他引:4
Four hundred and seventy-two consecutive referral episodes relatingto 386 patients attending the Occupational Health Departmentof a general teaching hospital were analyzed to evaluate thefrequency, content and effect on management of communicationsbetween the occupational physician and other doctors. In all,250 episodes (53%) were associated with such a communication.The likelihood of a communication was strongly influenced byreason for referral, particularly in respect of long or shortterm sickness absence; univariate odds ratios (OR)=10.58, 95%Cl=8.1327.08) and 2.65, 95% Cl=1.554.60) respectively;a medical diagnosis of psychiatric illness (OR=3.17, 95% Cl=1.695.97));and by number of consultations. Communication was also morelikely when the occupational outcome was ill health retirement,rehabilitation in work or modified work. Ninety-eight per centof specific requests for information or an opinion eliciteda reply. Information received from other doctors influencedthe occupational health physician's management in 52 referralepisodes (20%). Specific action by GPs as a result of communicationwas documented in 54 and by specialists in 37 episodes. Theimportance of communication between occupational health physicianand other doctors in the occupational health process is confirmed. 相似文献

In an independent learning project, 52 third-year medical students carried out a structured self-assessment of two videotaped psycho-social interviews they had conducted with volunteer clients 1 year earlier, as part of a previous course. The interviews had been conducted in small tutorials with feedback from their clients, fellow students and tutors, facilitated by videotape playback. During the sequence of 16 tutorials each student had carried out an early and a late interview and had observed and participated in the discussion of the interviews of 14 peers. Students were asked to tally the frequencies of various interview behaviours, to evaluate the quality of their behaviours, and to establish priorities for future learning. The videotapes were also reliably rated by an independent observer. Students' overall self-assessments correlated 0.46 with those of the independent observer. This correlation was higher than is typically reported in studies of the validity of self-assessment. In absolute terms, the students' mean rating of interviewing performance was 3.2 (adequate plus) which was significantly lower than the observer's mean of 3.6 (adequate to good). Results are discussed in terms of Gordon's (1992) two recommendations for improving the validity of self-assessments and two further suggestions, for paired comparisons and low-threat learning environments, are added. 相似文献
