Physicians' reasons for not entering eligible patients in a randomized clinical trial of surgery for breast cancer.

We studied the reasons surgical principal investigators chose not to enter patients in a large, multicenter trial sponsored by a cooperative group. In 1976 the National Surgical Adjuvant Project for Breast and Bowel Cancers (NSABP) initiated a clinical trial to compare segmental mastectomy and postoperative radiation, or segmental mastectomy alone, with total mastectomy. Because the low rates of accrual were threatening to close the trial prematurely, we mailed a questionnaire to the 94 NSABP principal investigators, asking why they were not entering eligible patients in the trial. A response rate of 97 per cent was achieved. Physicians who did not enter all eligible patients offered the following explanations: (1) concern that the doctor-patient relationship would be affected by a randomized clinical trial (73 per cent), (2) difficulty with informed consent (38 per cent), (3) dislike of open discussions involving uncertainty (22 per cent), (4) perceived conflict between the roles of scientist and clinician (18 per cent), (5) practical difficulties in following procedures (9 per cent), and (6) feelings of personal responsibility if the treatments were found to be unequal (8 per cent). Further investigation into the behavioral aspects of the investigator-patient relationship is particularly pressing, since fear of change in this relationship was the most common reason given for not entering eligible patients in the trial.

WAIS-III Matrix Reasoning test performance in a mixed clinical sample.

This study examined the relationship between the Matrix Reasoning subtest (MRT) of the WAIS-III and a selected number of neuropsychological tests in a heterogeneous clinical sample of English-speaking American (n = 41), and non-English-speaking immigrant (n = 14) adults. A moderate association between the Halstead Category Test and the MRT (-.58) was found in the English-speaking sample. Multiple regression analysis revealed a significant association between measures of verbal abstract reasoning and verbal fluency, and performance on the MRT. Among the immigrant sample, the MRT was also found to be significantly associated with verbal fluency task performance, as well as with the Comprehensive Test of Nonverbal Intelligence. Correlational analyses therefore suggest a strong verbal mediation element in the MRT, and that labeling it a nonverbal task may be misleading.

Reasons for replacement and the age of failed restorations in posterior teeth of young Finnish adults.

Using dentist characteristics, our aim was to evaluate the reasons for replacements of fillings, the age of failed restorations in the posterior teeth of young adults, and replacement rates. Altogether 205 patient records from the Public Oral Health Service of the City of Vantaa, Finland were evaluated. Patient age was restricted to between 25 and 30 years and type of tooth to posterior teeth only (third molars excluded). Information collected from the records included the patient's date of birth, latest DMFS and DMF, and the code for background data on the dentist. Details of each filled premolar and molar included the restorative material, location, and surface coverage of filling(s). The age of replacement of filling in premolar(s) or molar(s) was screened retrospectively from patient records. The total number of filled premolars and molars was 1873, with 1969 fillings. Forty percent of the patients had undergone replacement of filling in premolar(s) or molar(s). In all, 140 replacements had been made, accounting for 6.9% of amalgam fillings and 8.5% of tooth-colored fillings. Secondary caries, along with fractures, overhangs, and marginal discrepancy, was the most common reason for replacement. The mean age of failed amalgam fillings was 8.9 years (SD 5.2) and of failed tooth-colored fillings 2.4 years (SD 1.6). In the public sector, female dentists form the majority and their replacement rate for amalgam fillings was twice that of male dentists (7.6% vs 3.2%; P = 0.01).

Reasons for restorative therapy and the longevity of restorations in adults.

The aim of this study was to obtain information on the restorative dental care of adults in Finland. A random sample of private dentists was drawn from the register, and in spring 2000 they were sent a questionnaire requesting them to record information for each restoration placed during one ordinary working day. A total of 800 dentists were contacted and 548 responded. The dentists reported placement of 3,455 restorations. Of these, 5% were Class I, 36% were Class II, 13% were Class III, 9% were Class IV, 21% were Class V, and 16% were extensive restorations including 4 or more surfaces. Overall, composite resin was the most common restorative material, and it was used in 79% of the restorations, whereas amalgam was used in 50%, compomers in 4%, and glass ionomers (either conventional or resin-modified) in 7% of cases. In 5%, of the cases, the tooth was restored with indirect restorative methods, using either gold or ceramic materials. Of the treatments, 65% were replacements of previous restorations. Secondary caries was the most common reason for replacement (36%, 52%, and 41% for composite, glass ionomer, and amalgam, respectively). Other common reasons were fractures of the tooth or restoration (23%, 11%, and 22% for composite, glass ionomer, and amalgam, respectively) and lost composite restorations (16%). The median age of failed restorations was 15 years for amalgam, 6 years for composite, and 7 years for conventional glass ionomer. Although the longevity of tooth coloured restorations was shorter than that of amalgam, comparisons with our previous studies indicate improved survival periods for tooth coloured materials.

Incidence of, and reasons for, tooth mortality among mentally retarded adults during a 10-year period.

The aim of the study was to investigate the reasons for, and incidence of, tooth mortality over a 10-year period in mentally retarded adults receiving regular dental care. The number of teeth present in 115 individuals (mean age in 1984 was 41.0, range 19-83 years) was registered in 1984 and 1994. The reasons for tooth mortality, medication utilization, frequency of dental care visits and cooperation during dental treatment were registered and related to tooth loss. The average incidence of tooth mortality was 3.72 teeth during the 10-year period. The mean number of dental care visits per year was 6.6. Most of the 428 teeth (58%) were lost due to periodontal disease. The preventive dental care given was not sufficient to arrest oral diseases. The data indicate, however, that achievement of cooperation in dental care situations not only makes dental treatment possible, but also leads to a decreased incidence of tooth mortality.

Long-term results and reasons for failure of intranasal endoscopic dacryocystorhinostomy.

The aim of this study was to evaluate the long-term results and the factors influencing the success in patients with nasolacrimal duct obstruction treated with intranasal endoscopic dacryocystorhinostomy (DCR) and silicone tube intubation (STI). We prospectively investigated 158 patients with lacrimal obstruction in two groups, one of which comprised 108 patients treated primarily with intranasal endoscopic DCR by experienced surgeons and the other comprised 50 patients who were operated on by inexperienced surgeons. In a mean follow-up time of 49 months the surgical success was 94.4% in experienced hands and 58.0% in inexperienced hands. The endoscopic examination of six patients with failure in the first group revealed granulation tissue around the tube in four, atonic sac in one and persistence of bone that was supposed to have been excised in the nasal cavity in one. There were 21 failures out of 50 patients in the second group: granulation tissue in 2 cases, fenestration to the nasolacrimal duct instead of the sac in 6 cases, synechia between the lateral nasal wall and the middle turbinate in 2 cases, bony spicles causing obstruction in 5 cases and fenestration anterior to the sac in 2 cases. In 4 cases no reasons were found for failure, but perhaps the small fenestration and failure to remove the medial half of the membranous sac wall was the reason. DCR and STI can be performed for primary treatment in lacrimal obstruction. There is a learning curve for the operation. False localization of the lacrimal sac, granulation tissue formation around the tubes, retained bony spicles, inadequate removal of the medial wall of the sac and the synechia between the lateral wall and the middle turbinate are the most common causes of failure.

The myth of the best argument: power, deliberation and reason.

Power in communication takes two main forms. As 'external' power, it consists in the ability to acknowledge or disregard a speaker or a discourse. As 'internal' power, it is the ability of an argument to eliminate other arguments by demonstrating its superiority. A positive or negative value may be ascribed to these forms of power. Four ideal-typical positions are discussed--strategy, technocracy, constructionism, and deliberation. Public deliberation has three virtues--civic virtue, governance virtue and cognitive virtue. Deliberation lowers the propensity to, and the benefit of, strategic behaviour. It also increases knowledge, enhancing the quality of decisions. For Habermas, the unity of reason is expressed in the possibility of agreement on the most convincing argument. However, sometimes conflicts are deep-lying, principles and factual descriptions are profoundly different, and uncertainty is radical. The best argument cannot be found. There is no universal reason. The question is whether non-strategic agreement may spring from the incommensurability of languages. In search of an answer, Rawls's concept of overlapping consensus, the feminist theory of the public sphere, and the idea of deliberation as co-operation are discussed. The argument developed is that the approach to deliberative democracy may be renewed by rethinking its motivational and cognitive elements. Public deliberation is grounded on a pre-political level of co-operation. Intractable controversies may be faced at the level of practices, looking for local, contextual answers.

Reasons for adopting technological innovations reducing physical workload in bricklaying.

In this paper the adoption of technological innovations to improve the work of bricklayers and bricklayers' assistants is evaluated. Two studies were performed among 323 subjects to determine the adoption of the working methods, the perceived workload, experiences with the working methods, and the reasons for adopting the working methods. Furthermore, a comparison of the results of the studies was made with those of two similar studies in the literature. The results show that more than half of the sector adopted the innovations. The perceived workload was reduced. The employees and employers are satisfied with the working methods and important reasons for adoption were cost/benefit advantages, improvement of work and health, and increase in productivity. Problems preventing the adoption were the use of the working methods at specific sites, for instance in renovation work. The adoption of the new working methods could perhaps have been higher or faster if more attention had been paid to the active participation of bricklayers and bricklayers' assistants during the development of the new working methods and to the use of modern media techniques, such as the Internet and CD/DVD.

The regressive effects of frustration upon the concrete reasoning ability of seven and eight-year-old-boys.

Forty-four seven- to eight-year-old boys were divided randomly into a experimental group and a contro group. All children took Forms A and B of the Concrete Reasoning Test as arranged by Siegelman and Block (12) and originally constructed by Smedslund (13). In the experimental group, each boy took Form A first and then was told that he could win a prize, which he selected from several items offered, if he could put together an easy puzzle (which was difficult in actuality). Each boy was given three minutes to work on the puzzle and was then given Form B. After each item he was allowed to work again on the puzzle for three more minutes. The individuals in the control group followed the same procedures, except that they had a much easier task to perform. It was hypothesized that (a) frustrated boys at a high level of concrete reasoning ability will regress less than frustrated boys at a lower level with the exception that (b) boys in the transitional period of thinking will regress more than those who are not, and (c) those boys who are frustrated will tend to regress more than those who are not. The results supported all of these hypotheses.

Moral reasoning of Piagetian-matched retarded and nonretarded children and adolescents.

The moral reasoning of four IQ/etiology groups was investigated: 19 organically abnormal moderately retarded, 19 organically abnormal mildly retarded, 19 mildly retarded due to psychosocial disadvantage, and 19 nonretarded individuals. In each group 12 Ss were preoperational and seven concrete operational. Moral reasoning was assessed by an instrument using moral dilemmas based on Kohlberg's procedures. The Slosson Intelligence Test was used to determine the IQs and mental ages of each S. Piagetian stage was determined with the standard conservation of number tasks. The findings indicated no overall significant differences between the mildly retarded and the nonretarded Ss or between the mildly retarded and the moderately retarded Ss, but differences were found between the moderately retarded and the nonretarded Ss. A significant interaction was found between the two independent variables, IQ/etiology and cognitive level. The results were discussed as supporting Zigler's development position and as damaging to Kohlberg's position.

Coping strategies from the perspective of two developmental markers: age and social reasoning.

In this study, we examined coping from a developmental perspective, including its relation to age and social cognitive maturity. The 60 participants, who ranged from adolescents to mature adults, were given Lazarus' Ways of Coping Scale. This consists of both an emotion-focused and problem-focused coping score and two measures of social reasoning performance. Social reasoning was the best predictor of emotion-focused coping, above and beyond years of education and age. None of the developmental variables predicted problem-focused coping. Analyses examining the effect of perceived controllability of the stressful situation on coping demonstrated that it differentially mediated choice of coping strategy across age groups. Whereas older participants endorsed more problem-focused strategies in perceived controllable situations and emotion-focused strategies in perceived uncontrollable situations, adolescents endorsed emotion-focused and defensive coping styles, irrespective of perceived controllability. Implications for the study of development of coping styles in affectively salient contexts is discussed.

Influence of the reason for the other's affect on preschoolers' empathic response.

Forty-six preschoolers were individually presented four slide-sequence stories in which the main character performed acts that resulted in the character displaying happiness (in two stories) or sadness (in two stories). Within each happy and sad story pair, one story portrayed the main character as having an "acceptable" reason for his or her affect (e.g., the character was happy after finding a friend to play with) and one story portrayed the character as having an "unacceptable" reason for his or her affect (e.g., the character was happy after transgressing against another child). Affective and evaluative responses to the main characters in the four stories were assessed. The preschoolers generally empathized more with (and evaluated more favorably) a story character whose affect was associated with the performance of an acceptable rather than an unacceptable act.

Patterns of nonverbal behavior among adolescents responding to a formal reasoning task.

This study investigated nonverbal behavior patterns of 11 adolescents who responded to the Inhelder-Piaget (1958) balance task, which provides an assessment of proportional reasoning and was the first study of how students behave while being assessed for formal reasoning ability. Interdependency among the precisely defined categories of behavior was found, even when the categories were collapsed on a conceptual basis. Consequences of this categorical interdependency were discussed.

Body image dissatisfaction: gender differences in eating attitudes, self-esteem, and reasons for exercise.

Two hundred and thirty-five adolescents completed a questionnaire on the subject of eating attitudes, self-esteem, reasons for exercise, and their ideal versus current body size and shape. As predicted, boys were as likely to want to be heavier as lighter, whereas very few girls desired to be heavier. Only girls associated body dissatisfaction with the concept of self-esteem. Male self-esteem was not affected by body dissatisfaction. Specific reasons for exercise were found to correlate with low self-esteem and disordered eating, regardless of sex. The results are discussed in relation to burgeoning published research in this area.

Gender differences in reasons for entering and leaving education administration: discriminant function analyses.

Using discriminant function analyses on survey data collected from 457 students in 29 education administration programs across the United States, the authors inquired into whether men and women decide to enter and possibly leave education administration for different reasons. There were statistically significant functions separating men and women in their reasons for entering and leaving education administration. Implications of the findings are discussed.

Influenza vaccine coverage and reasons for non-vaccination in a sample of people above 65 years of age, in Sweden, 1998-2000.

Influenza vaccination for the elderly has been shown to be effective. The Swedish national recommendations are that people over 65 y, and especially those with chronic cardiac and/or pulmonary disease, should be immunized annually. However, implementation of such programmes has often been far from successful. The aims of this study were to estimate vaccine coverage and especially reasons for not being vaccinated in a group of elderly people who were all clearly included in the national recommendations. The study investigated people over the age of 65 y who lived in special apartments, 'service homes', connected to the community care for the elderly in the municipality of Linköping, Sweden. The data were collected from the middle of May to the middle of July during 3 years, 1998, 1999 and 2000. Data were gathered by interviewing a sample of 210 tenants each year. All interviews were conducted using a standard questionnaire. The vaccination coverage for influenza in this population was found to be as low as around 30%. The main reason reported for non-vaccination was a lack of knowledge of the recommendations. The results clearly demonstrate that the single most important factor needed to attain high coverage is information, both to the people defined to be at risk and to health-care professionals.

College students' reasons for nonuse of condoms within dating relationships.

Two hundred ten heterosexual undergraduates in dating relationships were surveyed about reasons for not using condoms every time for vaginal and anal sex and for increasing or decreasing condom use during their relationships. Half of the respondents reported consistent condom use in the first month of their relationships, while only 34% reported consistent condom use in the past month. Subjective assessments of partner safety and the belief that sufficient measures were being taken to avoid pregnancy were important reasons for condom nonuse. Study results suggest that interventions should emphasize the importance of objectively assessing HIV/STD risk before reducing condom use within relationships. Interventions also need to provide additional information on the riskiness of heterosexual anal sex.

Teaching Bayesian reasoning: an evaluation of a classroom tutorial for medical students.

How likely is a diagnosis, given a particular medical test result? This probability can be determined by using Bayes's rule; however, previous research has shown that doctors often experience problems with Bayesian inferences. These findings illustrate the need to teach statistical reasoning in medical education. A new method of teaching Bayesian reasoning is representation learning: the key idea is to instruct medical students how to translate probability information into a representation that is easier to process, namely natural frequencies. This approach was implemented in a one-hour classroom tutorial to evaluate its effectiveness in this setting and compared with a traditional rule-learning approach. Evaluation took place two months after training by testing students' ability to correctly solve a Bayesian inference task with information represented as probabilities. While both approaches improved performance, almost three times as many students were able to profit from representation training as opposed to rule training.
