This study was a randomised control trial with a waiting control group. It was designed to evaluate the effectiveness of a 6-month, group-based diabetes prevention programme, The Healthy Living Course and assess whether participation in the programme led to changes in modifiable risk factors for type 2 diabetes among an already at-risk pre-diabetic population. Individuals designated at risk for diabetes by their general practitioners (GPs) were screened using an Oral Glucose Tolerance Test. Volunteers (N?=?307) with pre-diabetes were assigned to an intervention or wait-control group in the ratio of approximately 2?:?1. The sample was pre-tested on biochemical, anthropometric and self-report behavioural, cognitive and mood variables and post-tested either at the end of the educational/support-based lifestyle programme or the end of the wait period. The intervention group significantly improved their diabetes knowledge, motivation to change, positive affect, healthy eating and activity levels and showed significantly greater reductions in weight, body mass index, waist circumference, diastolic blood pressure and fasting plasma glucose in comparison with controls. The intervention group also changed their diagnostic status from pre-diabetes to non-diabetes at a greater rate than the wait group (43% vs. 26%) who received standard care from their GPs.  相似文献

Short-Term Psychoanalytic Supportive Psychotherapy (SPSP) is a face-to-face, individual psychotherapy, consisting of sixteen sessions in six months (first eight weekly, then eight fortnightly sessions). It is rooted in psychoanalytic theory. Its primary aim is to cure depression. A secondary goal is to reduce a patient's vulnerability to depression. The emphasis is on supportive techniques that counter regression and foster psychological growth. The putative process consists in experiencing a relational dissonance, i.e., feeling two contradictory relationships in the therapeutic situation simultaneously, one determined by the past, the other by the present. We assume an important curative factor is to experience, mostly unconsciously, an adequate gratification of developmental needs inadequately met in early infancy and, therefore, manifesting themselves in the archaic aspects of the therapeutic relationship. SPSP unfolds as a discourse in which we distinguish nine levels. Each regards a specific subject, which at that level is the focus of the interaction between patient and therapist. The efficacy of SPSP in ambulatory patients presenting a DSM-IV defined, mild to moderate major depressive disorder has been tested in five randomized clinical trials. The results have been aggregated in a mega-analysis. They suggest that, in the treatment of outpatients with mild to moderate major depressive disorder, SPSP and pharmacotherapy are equally efficacious and that the combination of SPSP and pharmacotherapy is more efficacious than pharmacotherapy alone but not than SPSP alone. We, therefore, consider SPSP a valuable extension to the existing options for the treatment of depressed patients.  相似文献

The current research examines tacit coordination behavior in a lottery selection task. Two hundred participants in each of three experiments and 100 in a fourth choose to participate in one of two lotteries, where one lottery has a larger prize than the other. Independent of variations in the complexity of the mechanism of prize allocation, the prize amounts, and whether the lottery is the participant's first or second choice, we typically find that the percentage of participants who choose the high versus low‐prize lotteries does not significantly differ from the equilibrium predictions. This coordination is achieved without communication or experience. We additionally find that participants with an analytical thinking style and a risk‐averse tendency are more likely to choose the low‐prize lottery over the high‐prize lottery. This tendency seems to be stable across choices. The pattern of our results suggests that to achieve tacit coordination, having a subset of individuals who attend to the choices of others is sufficient.

Ratings on a creativity rating scale of students' designs of a hands-free mobile phone holder were compared for 2 sets of raters: experts (professional art teachers) and novices (visual art students). Reliabilities of total creativity scores were high for both groups, and interjudge consistency on total creativity scores, as well as on grades, was high among novices, but not as high among experts. Correlations between grades and total functional creativity scores within and across groups of raters (experts and novices) were highly significant. Scores on the scale resembled those yielded by assessments using grades and the scale did not yield better consistency among judges than conventional grades. Nonetheless, it provided a differentiated assessment of products that made it possible to explain the basis of experts' opinions and the reasons for disagreement, and to discuss the strengths and weaknesses of students' designs in a systematic and differentiated way.  相似文献

Abstract

Practices of ordering are powerful means of giving structure to people's lives and providing a sense of control. The analysis of three episodes from discussion groups on nanotechnology in Austria shows that citizens evaluate new technologies with regard to how they intersect with, support, or disturb existing orders. The concept of discursive assemblages serves as a lens for recognising the non-fixed character of the discursive process, while still allowing the analyst to identify how specific elements, such as conceptions of nature, culture, and technology, are (re)assembled at particular moments. Each of the three episodes represents a specific way of creating and negotiating assemblages: the first case demonstrates how discussants collectively discuss a nature–technology hybrid (nano-bamboo socks) against the backdrop of a highly valued ideal of keeping ‘the natural’ and ‘the technological’ separate; the second episode exemplifies a clash of two assemblages as participants argued for or against the application of nanotechnology in food products; and the third example illustrates the process of collective experimentation with different assemblages to make sense of a highly futuristic nanochip for brain enhancement. Together the episodes demonstrate that participants in public engagement settings do not address nanotechnology as a simple question of choice between acceptance and rejection but rather engage in processes of care regarding how a society might develop when technological innovations such as nanotechnology threaten to blur existing boundaries and orders, such as the distinction between nature and culture.  相似文献

The ease with which information comes to mind can impact judgment. We examine whether the influence of ease of retrieval is moderated by situational factors that call it to attention before judgment and by individual differences in experiential processing style, as measured by the rational experiential inventory scale (Pacini & Epstein, 1999). An ease of retrieval effect, indicated by less favorable evaluations of a proposal following the retrieval of many reasons advocating the proposal than following the retrieval of only a few, was found for high‐experiential style processors regardless of situational factors that made ease of retrieval salient. However, the effect was found among low‐experiential style processors only when ease of retrieval was explicitly called to their attention prior to judgment.  相似文献

The Alarm Distress Baby Scale (ADBB) aims at assessing infant withdrawal behavior. A previous validation study revealed acceptable reliability and validity indices. The present study investigated the psychometric properties of the scale in a larger sample from a culturally different population. Pediatricians evaluated the behavior of 122 infants, 2 and 19 months old, using the ADBB during routine physical consultation. Four investigators (two pediatricians and two nurses not specialized in pediatric care) examined video recordings of the evaluations. Results showed good interrater reliability coefficients among pediatricians and poor correlation when all professionals were grouped together. Test–retest reliability revealed good intraexaminer agreement (r = 0.91). The pediatricians' evaluation using the ADBB was compared with a psychiatric examination to investigate the scale's criterion validity. The cutoff point of 5 provided the best clinical validity (sensitivity of 79%, specificity of 81%). Results from construct validity showed that the scale had three dimensions. Comparison of the factor solution with other construct validity studies of the same instrument revealed similarities and differences. Results suggest that the ADBB may be a useful screening instrument to detect signs of psychiatric alterations related to withdrawal behavior in primary care services, and it is likely to provide consistent information.  相似文献

Evaluative categories include items that share the same value- laden assessment. Given that these categories have not been examined extensively within the child concepts literature, the present research explored evaluative categorization and induction within the domain of food as a test case. Specifically, two studies examined the categories of healthy and junky foods in children aged 4 and 7 years. Study 1 showed that by aged 4 years, children appropriately apply the evaluative categories of healthy and junky foods to a variety of different foods. Study 2 showed that by age 4 years, children also selectively use the evaluative categories of healthy and junky foods for inductive inferences about the human body, but not for arbitrary or unrelated inferences. Taken together, these results highlight the importance of evaluative processing in young children's categorization and induction.  相似文献

This paper attacks one of the chief limitations of the field of behavioral decision research—the past inability to use this literature to improve decision making. Building on the work of Thompson, Gentner, Loewenstein and colleagues (Loewenstein, Thompson, & Gentner, 1999; Thompson, Gentner, & Loewenstein, 2000; Gentner & Markman, 1997), the current paper finds that it is possible to reduce bias in one of the most robust problems in the decision literature, the Acquiring a Company Problem (Samuelson & Bazerman, 1985). Past research has shown that individuals make suboptimal offers as a result of the failure to think about the decisions of others and to incorporate a clear understanding of the rules of the game. In the current study, we find that by allowing study participants to see and understand differences in seemingly unrelated decision problems—versions of the Monty Hall Game (Nalebuff, 1987; Friedman, 1998) and Multiparty Ultimatum Game (Messick, Moore, & Bazerman, 1997; Tor & Bazerman, 2003)—study participants can learn to focus more accurately on the decisions of other parties and the rules of the game, the keys to solving the Acquiring a Company Problem. This research offers a new piece of evidence that comparative and analogical processes may be a successful direction for improving decision making. Copyright © 2004 John Wiley & Sons, Ltd.  相似文献

This article addresses the effects of flexible work-time designs on employee- and company-related aims. Using objective and self-reported quantitative and qualitative data the current study examines the effects of a flexible work-time design that was introduced in a service company in Germany. Building on the learning hypothesis of the job demands?–?control model, we predicted that a highly flexible work-time design that provides employees with high demands but at the same time also with a high degree of autonomy, and self-determination over their working time leads to positive effects on employee's personal development and learning opportunities. The results supported this hypothesis. However, in addition to employee-related benefits the results also suggested benefits for the company, such as an increase in adherence to company goals. Moreover, the objective data showed a lower degree of absenteeism and higher work quality compared to the control group working with the traditional work-time design. Theoretical and practical implications are discussed.  相似文献
