Psychology of computer use: XXIII. Validating a measure of computer-related stress.

Prediction of the final grade in a computer course using the Computer Technology Hassles Scale, a measure of computer-related stress, was investigated. A sample of 154 university students enrolled in computer courses completed questionnaires covering demographic data, information on computer use, the Computer Technology Hassles Scale, and somatic complaint items of the Hopkins Symptom Checklist. Pearson correlations indicated scores on the Computer Technology Hassles Scale were significantly associated .27 with somatic complaints, -.24 with computer-course grades, and -.18 with self-rated computer knowledge. Regression analysis indicated that self-rated computer knowledge and scores on the Computer Technology Hassles Scale significantly predicted computer-course grade.

Computer skills and attitudes to computer-aided learning among medical students.

One hundred and forty-four third-year medical students at the University of Edinburgh were surveyed as to levels of computing skills and confidence in carrying out computing tasks. Attitudes to computer-aided learning for clinical teaching were also measured. Thirty-one per cent of students had not used a computer in the previous year and 38% had not used a computer outside supervised laboratory work. Twenty-two per cent had never used the university library computerized catalogue and 43% had never carried out a medline search using the library CD-ROM. Students were not confident of their ability to carry out simple computing tasks. Fifty-four per cent said they would need support or instruction in printing out a document, 69% were not confident they could copy a file onto a disk and 74% did not believe they could independently create a graph in a document. Students who had completed an intercalated honours year were significantly more skilled and confident in computing tasks. Attitudes to computer-aided learning were related to computing confidence. Medical students who have not acquired basic computer information technology (IT) skills by the third year of undergraduate training are unlikely to do so in the final hospital-based years. Undergraduate curricula for medical students must incorporate specific computer (IT) training.

Assessment of the completeness and accuracy of computer medical records in four practices committed to recording data on computer.

BACKGROUND: General practice computer databases are being increasingly seen as a source of data for public health monitoring and commissioning. Such ambitions depend on routine clinical data being recorded with acceptable completeness and accuracy. AIM: The aim of this study was to assess the completeness and accuracy of the computer medical records in four high-recording general practices. METHOD: Four general practices in the Trent Region that use the EMIS computer system, and were known to be high recorders of clinical data on their computer databases, were selected. A retrospective analysis of the computer records, a prospective comparison of a sample of computer records with manual records, and a prospective comparison between videorecorded consultations and their manual and computer records were undertaken. RESULTS: Checks for completeness in computer recording of diabetes mellitus and glaucoma showed high levels of accurate recording, 97% and 92% respectively. Prevalence rates between practices were reasonably comparable. No practice consistently, across 10 diagnoses, recorded prevalences higher or lower than the other practices; those diagnoses with recognized objective diagnostic criteria were recorded with a more consistent prevalence than those without. Lifestyle data recording was low; overall, smoking habits and alcohol consumption were recorded for 52% and 38% of patients aged over 16 years, respectively. Comparison of the manual records with the computer records showed that the computer records were sufficiently complete with regard to diagnoses (82% of all items recorded), prescriptions (100%) and referrals (67%), but missed most of the remaining data that a manual record captured. The videorecorded validation study showed that there were no important lapses in the recording of diagnoses, prescriptions or referrals when the computer recording was compared to the actual process of the consultations. CONCLUSION: In these four high-recording practices the data in computer records were of sufficient completeness and accuracy to allow meaningful data aggregation for some diagnoses, prescriptions and referrals. Standardized protocols for defining which patients are included and excluded from major disease groups are required.

Psychology of computer use: XLII. Problem solving and humor as a function of computer anxiety.

From a pool of 115 undergraduate women, 20 were placed in a Computer-anxious group and 20 in a Computer-nonanxious group based on their scores on the Computer Anxiety Scale. Half of the subjects were randomly assigned to a group to which the computer presented the problems first and half to a group to whom the computer presented the jokes first. Electromyograms from subjects' zygomatic muscles were monitored as well as palmar skin conductance. Behavioral measures were collected prior to and following the computer interaction. Although the electromyogram for zygomatic tension (smiles) was higher in the jokes condition, indicating that subjects responded to jokes as humorous, Computer-anxious subjects showed increased scores on anxiety and depression and relatively high skin conductance on the initial joke. Subjects with high computer-anxiety had less experience with computers, had lower scores on the Rosenberg Self-esteem test, and, likely not being familiar with computer humor, reacted anxiously.

Computer use, computer training, and employment. Outcomes among people with spinal cord injuries.

Computer use and training may be of special benefit to people with spinal cord injuries (SCIs) because computer technology may help lessen the impact of mobility limitations that are inherent with this disability. This article summarizes several findings from a 1994 survey conducted of New Jersey residents who suffered SCIs within the previous 10 years. The results indicate that, among people with SCIs, 46% currently use a computer in some capacity and 22% received computer training since the date of their injury. Perhaps surprisingly, both corresponding percentages are higher in the general population. People with SCIs appear to have less access to computers because most people learn how to use computers at work, and only a minority of people with SCIs work. The lower rate of use of computers among people with SCIs is unfortunate because the steep employment and earnings declines often experienced after an SCI are partially mitigated for those who have computer skills. The results suggest the importance of policies and programs aimed at increasing access to computers and computer training for people with severe disabilities.

Work stress in Japanese computer engineers: effects of computer work or bioeducational factors.

To examine whether computer work and bioeducational factors (age and school career) have significant effects on work stress in computer engineers in Japan, we administered a stress questionnaire to 764 male computer engineers and 211 male office workers in a computer-manufacturing factory in Tokyo. Four scales of perceived psychological stress at work examined were work overload, poor human relationships at work, unsuitable job, and competition-dismissal anxiety. The results of the three-way analysis of variance, in which age (20-29, 30-39, and 40-49 years), school career (high school and university graduates), and computer work (computer engineers and office workers) were three variation factors, indicated that: (1) there were no significant differences in all scores of work stress between computer engineers and office workers (P > 0.05); (2) scores for unsuitable job and poor human relationships at work were significantly higher in high school graduates than in university graduates (P < 0.05); and (3) there were significant age differences in scores for three scales of work stress (unsuitable job, competition-dismissal anxiety, and work overload: P < 0.001, P < 0.01, and P < 0.05, respectively). These findings suggest that computer work has no significant effect on perceived work stress in computer engineers; on the other hand, age and school career do have effects.

Educational Technology Network: a computer conferencing system dedicated to applications of computers in radiology practice, research, and education.

Educational Technology Network (ET Net) is a free, easy to use, on-line computer conferencing system organized and funded by the National Library of Medicine that is accessible via the SprintNet (SprintNet, Reston, VA) and Internet (Merit, Ann Arbor, MI) computer networks. It is dedicated to helping bring together, in a single continuously running electronic forum, developers and users of computer applications in the health sciences, including radiology. ET Net uses the Caucus computer conferencing software (Camber-Roth, Troy, NY) running on a microcomputer. This microcomputer is located in the National Library of Medicine's Lister Hill National Center for Biomedical Communications and is directly connected to the SprintNet and the Internet networks. The advanced computer conferencing software of ET Net allows individuals who are separated in space and time to unite electronically to participate, at any time, in interactive discussions on applications of computers in radiology. A computer conferencing system such as ET Net allows radiologists to maintain contact with colleagues on a regular basis when they are not physically together. Topics of discussion on ET Net encompass all applications of computers in radiological practice, research, and education. ET Net has been in successful operation for 3 years and has a promising future aiding radiologists in the exchange of information pertaining to applications of computers in radiology.

[The world of computer games II: a demographic study on prevalence of computer players in secondary school students].

The article presents the results of the first stage of our own research on the popularization of computer games among adolescents. A questionnaire was filled by 2678 class one pupils of secondary schools (born in 1979). The investigations were aimed at selecting a group of secondary school pupils particularly interested in computers and computer games. The investigations proved that the problem of computer games playing regards more than a half of the school pupils population we examined. There are twice as many boys as girls among the computer games players. Also, boys have better knowledge of computer games, they start to play at a younger age, devote more time to playing these games. The most popular hardware are Amiga or IBM compatible PCs. As many as 3/4 of computer games players have their own computers. The most significant information was the data concerning the time devoted to playing, both daily and weekly. The investigations show that boys spend much more time playing computer games than girls do. The selected group of pupils will undergo detailed clinical as well as psychological examination.

Computational and noncomputational clinical information processing by computer.

Computers have been used in their computational as well as noncomputational modes for the scientific study of the clinical decision making. As computational tools, computers serve as storage devices for hospital file data so that these data can be analyzed statistically for a large variety of epidemiological and diagnostic purposes. As noncomputational devices, computers are functioning as knowledgable medical teachers that interface with students who can query the system. In this mode, computers are sometimes used as consultants to clinicians who need information on technical topics. Noncomputational computers are also used to simulate the inferences of clinicians. Byproducts of these simulations are computer programs that become formal statements or theories of the decision processes under investigation.

Medical education and computer literacy: learning about, through, and with computers.

The call for medical students to become literate in the uses of information technology has become a familiar refrain. Over ten years ago, the Association of American Medical College's GPEP Report recommended that medical schools incorporate into their curricula training in the use of such technology; however, in the intervening decade, discouragingly little progress has been made toward meeting this goal, even though the need for such changes has grown more compelling. The author contends that teaching medical students to be computer-literate will not only enable them to use information technology competently, but will foster their capacity for "termless learning," which involves the ability to assess the adequacy of one's knowledge, to efficiently redress identified deficiencies, and to direct one's ongoing learning well in a rapidly changing world. He contends that by exposing medical students early in their training to the vast profusion of electronic information resources, medical educators can help produce a generation of practitioners who have a different orientation toward knowledge and learning. The author then assesses three different approaches to computer-literacy training: learning about computers, learning through computers (i.e., using computers as tools for instructional delivery), and learning with computers (i.e., requiring students to use computers in their work on a day-to-day basis). He concludes that none of the approaches is sufficient unto itself, but learning with computers offers the most powerful means of fostering the forms of termless learning that students will need to practice medicine in the future.

[The significance of computed tomography in ophthalmologic diagnosis. I: The place of computed tomography, indications, study technics, anatomic representation, computed tomography of eyeball and orbital injuries].

CT is recognized today as method of choice for examining pathological conditions of eyeball and orbit. Several techniques of CT examination are needed to attain the most accurate and detailed information about orbital and eyeball lesions. The exact knowledge of the normal anatomic CT feature of orbital structures is necessary. In traumatic lesions of the globe and the orbit foreign bodies, haematomas and fractures of the orbital walls can be proved and localized and traumatic sequelae can be diagnosed.

Developing interactive computer-based simulations: an object-oriented development methodology enhances computer-assisted instruction.

The purpose of this research was to investigate the application of object-oriented technology and AI techniques to enhance development of computer-based training simulations. Towards that end, a comprehensive computer-assisted instructional unit was developed to teach the skills and concepts of window-based applications, the OS/2 desktop, and the use of a patient care information system. By taking advantage of sophisticated computer graphics for the visual representation of objects and the behavioral modeling capabilities of the object-oriented language, domain knowledge modeling and human-computer interactions were implemented without complex natural language processing techniques. The results of this research indicate that nurses and physicians are able to learn the basic skills and concepts of computer systems and how to query for patient information. The new methodology described for building these computer-assisted instructional simulations significantly eased the training and teaching of large numbers of nurses and physicians and simplified their transition to a complex, computer-based hospital information system environment.
