Identifying cytologic characteristics and grading endocervical columnar cell abnormalities. A study aided by high-definition television.

OBJECTIVE: To test the ability of cytotechnologists to recognize and accurately interpret selected architectural, cellular and nuclear features presented on a high-definition television (HDTV) and to make a reliable diagnosis with HDTV. STUDY DESIGN: A total of 1,122 features considered diagnostic of different endocervical columnar cell abnormalities were selected from 50 smears from 48 women with the help of a motor-driven-stage microscope by five observers who had knowledge of the final diagnosis. The selected and stored features were presented on an HDTV and evaluated in five successive sessions without knowledge of the final diagnosis. RESULTS: Specific types of features were correctly identified in a high number of cases. Considerable interobserver variability was demonstrated in the scoring of grades of expression of features. Overrated and under-rated monitor diagnoses were related to overvalued and undervalued features. From a group of 437 images that were correctly diagnosed by four or five observers, five features proved to be highly related to the correct diagnosis. CONCLUSION: Observers were capable of making a reliable diagnosis on features, selected by other observers, when presented on an HDTV. An overall correct diagnosis was made in 93% of cases.

Impact of dramatized television entertainment on adult males.

The authors studied the effects of a week's viewing of five types of television programs, including those with predominantly helpful or hurtful content, on the aggressive mood and hurtful behavior of adult men. They found, within the population studied, a significant decrease in aggressive mood and lower levels of hurtful behavior in viewers of helpful programs as compared with a control group, as well as some evidence that emotional arousal in response to helpful programs is negatively correlated with aggressive mood.

Fictional depiction of suicide in television films and imitation effects.

Studies of imitative suicide by viewers of fictional depictions of suicide in television films have produced contradictory findings. Using a nationwide sample of cases of suicide, the author found no evidence for increased numbers of suicides after broadcast of three films. However, some support was found for an imitation effect specific to the depiction of a suicide method in one of these films (p less than 0.05). To the extent that fictional presentations of suicide may serve as stimuli for imitative behavior, the effect appears to depend on a complex interaction among characteristics of the stimulus, the observer of that stimulus, and conditions of time and geography.

Cost-effectiveness of television, radio, and print media programs for public mental health education.

Mass media campaigns to influence public attitudes and behaviors in the area of mental health must consider cost-effectiveness, which is based on actual costs, the number of people reached (exposures), and the impact of the program on the individual. Cost per exposure is a critical factor. The authors review their experience in developing media programs in several broadcast formats and in print. Their experience suggests that an effective television production has a very high per-exposure cost and that radio is a more cost-effective way to present health messages. Radio programs also have the advantage of reaching people in their homes or cars or at work. Brief segments may be particularly cost-effective because they can be can be inserted between programs during prime-time hours. Print media--newspapers, magazines, and newsletters--can be cost-effective if magazine or newspaper space is free, but newsletters can be costly due to fixed postage costs. One advantage of print is that it can be reread, clipped out, copied, and passed on.

A comparative study of children's television programmes: American and Japanese.

American Children's Stories on Television (ACSTV) and Japanese counterparts (JCSTV) were analysed with emphasis on the transcultural element, according to the main theme and the features of the key characters. The most common theme of both ACSTV and JCSTV was authority. The authority figure in ACSTV was viewed as a competitor, while in JCSTV it was viewed as being evil. The intimacy of the mother-child relationship was prominent in JCSTV. In ACSTV, individualism was emphasised, while in JCSTV group affiliation was more emphasised.

Telepsychiatry: psychiatric consultation through two-way television. A controlled study.

Telepsychiatry (consultation carried out through 2-way interactive television) has been the object of a number of trials in the past twenty years, but to our knowledge there is no previous control study which compares CCTV and face-to-face interviews. Various aspects of the interviews carried out on CCTV were rated on a 5-point scale in questionnaires filled out by: (a) patients; (b) consultees and; (c) consultants. No significant difference was elicited with control interviews in respect to patients' diagnosis, age and sex. CCTV interview ratings by consultee and consultant were rated only slightly below those of the control group. Such findings should encourage a broader application of interactive CCTV, particularly as a complement to live consultations in distant areas.

Channeling health: a review of the evaluation of televised health campaigns.

This article reviews efforts to assess the effectiveness of television programs on changing health behaviors. The relatively limited literature to date has featured primarily correlational studies which permitted no causal conclusions. The few experimental studies available present a mixed picture. Numerous methodologic problems beset any effort at assessment of effectiveness. Perhaps the greatest difficulty is operationalizing a design that permits true experimental manipulation on a relevant sample without contamination. The several methodologic problems and some potential means of surmounting them are discussed.

Cable television and health promotion: a feasibility study with arthritis patients.

Community access cable television channels can be used to provide low-cost health programming in many communities. This article describes a study undertaken to ascertain the extent to which arthritis patients could be targeted by arthritis-related programming over a local cable system. A number of publicity sources were used to advertise the programs to a preidentified group and the public at large. Telephone and written surveys revealed that the programming garnered a moderate viewing audience composed preponderantly of arthritis patients. Some conceptual and practical issues involved in targeting chronic patient groups for health programming are discussed.

An evaluation of the use of interactive television in an acute psychiatric service.

This study reports the results of the use of a low-cost videoconferencing system (LCVC) for communication in an acute psychiatric service. Qualitative research methodology was used to examine the use of the LCVC in interactions between psychiatrists, patients and nursing staff, including information on refusals. One hundred and five clinical interactions were studied over four months. The LCVC proved technically reliable and compatible with the performance of a wide range of clinical tasks. However, the results suggest the need for better understanding of the nature and origins of the attitudes that users bring to the use of such communications technology. A framework is presented for the classification of user responses in terms of preexisting attitudes of the users, technological limitations of the system and the mental state of the users. The study demonstrated the potential for interactive television to support many of the communication tasks necessary in a dispersed psychiatric service and for telepsychiatry to become a major method of service provision.

Media influence on parasuicide. A study of the effects of a television drama portrayal of paracetamol self-poisoning.

BACKGROUND: Paracetamol self-poisoning, which carries a significant risk of fatal liver damage, is increasing in the UK, especially among adolescents. There is concern that media portrayal of suicidal behaviour may influence its occurrence. We have investigated the effects of two broadcasts of a television drama showing a teenage girl's overdose of paracetamol. METHOD: Data from the Oxford Monitoring System for Attempted Suicide were used to examine changes in the number of overdoses and the use of paracetamol in the three week period before and after both broadcasts. An analysis of log-linear models was carried out, using additional data from two previous years, in order to control for the effects of gender, age group, time period, season, year and drug. A questionnaire was used to ascertain whether the programme had influenced patients' decisions to take an overdose or their choice of drug. RESULTS: An increase in paracetamol overdoses occurred following the first broadcast, but when data from the two previous years were examined and the log-linear analysis was used there was no evidence of significant effects attributable to the broadcasts. The questionnaire study revealed that very few people had seen either episode, and only two claimed that it had influenced them (one in terms of getting help). CONCLUSIONS: It is important to use sound methodology to avoid interpreting chance fluctuations as a media effect. The potential positive benefits of such programmes should also be investigated.

Closed circuit television: a unique tool.

A closed circuit television station was instituted within the Children's Hospital of Winnipeg in April 1981. The station broadcasts commercial-free children's programming throughout the day with the highlight of the schedule being a 1-hour live broadcast each weekday. The personal, interactive format of the live program has made the show a unique and effective tool for reaching patients, helping individual patients accept different aspects of their care, teaching the children about the hospital, and simply boosting morale through making each child a part of the program.

An expectancy-value analysis of viewer interest in television prevention news stories.

Understanding what drives viewer interest in television news stories about prevention topics is vital to maximizing the effectiveness of interventions that utilize this medium. Guided by expectancy-value theory, this experiment used regression analysis to identify the salient beliefs associated with viewer attitudes towards these types of news stories. The 458 study participants were recruited over 30 days from a municipal jury pool in an eastern U.S. city. Out of the 22 beliefs included in the experiment, 6 demonstrated salience. Personal relevance, novelty, shock value, and the absence of exaggeration were the core values reflected in the identified salient beliefs. This study highlights the importance of explaining the relevance of prevention stories to viewers and framing these stories with a new spin or a surprising twist. However, such manipulations should be applied with savvy and restraint, as hyping prevention news was found to be counterproductive to educating the public.

Effects of exposure of youths at risk for smoking to television advertising for nicotine replacement therapy and Zyban: an experimental study.

Television advertising for nicotine replacement therapy (NRT) and Zyban exposes the entire population, including adolescents, to persuasive messages about these smoking-cessation products. There is a risk that adolescents exposed to the advertising might underestimate addictiveness or perceive an unintended message that it is easy to quit smoking. This is of concern because optimism about quitting is a major predictor of trial and progression to heavier smoking among youths. We randomly allocated 492 youths age 12 to 14 years to one of three viewing conditions in which they viewed either (a) 4 NRT ads, (b) 4 Zyban ads, or (c) 4 ads promoting nonpharmacologic cessation services, such as telephone quitlines. After viewing each ad twice, participants completed a 1-page rating form. After all ads had been viewed, youths completed a questionnaire that measured intentions to smoke in the future, perceived addictiveness of smoking, perceived risks and benefits of smoking, and perceived need for pharmaceutical products and services. There were no differences in the composition of groups by age, gender, or smoking uptake. Youths were more likely to agree that the NRT and Zyban ads, compared with the quitline ads, made it seem easy to quit smoking (p < .001). However, there were no systematic differences between groups in perceived addictiveness of smoking, intentions to smoke, or other outcomes. This study suggests that although ads for NRT and Zyban may create "face value" impressions that it is easier to quit, at least in an experimental context in which exposure to ads for telephone quitlines is equal, such appraisals do not undermine more enduring perceptions about smoking. Field research taking into account the relatively high volume of pharmaceutical cessation product advertising is needed.

Epilepsy provoked by television and video games: safety of 100-Hz screens.

Television (TV) and video games (VG) can provoke seizures in patients with photosensitive epilepsies. Flicker frequency is the most important factor in screen activation. We tested conventional 50-Hz versus 100-Hz monitors during TV viewing and VG playing in 30 photosensitive subjects, 23 of whom had a history of TV or VG seizures or both. Fifteen subjects' discharges were activated by 50-Hz TV; 17 by 50-Hz VG; and one by a 100-Hz screen. Thus, 100-Hz screens protect against screen activation.

Family structure and children's television viewing and physical activity.

OBJECTIVES: This study aimed to examine how physical activity (PA) and television (TV) viewing time of children varied according to family structure. METHODS: In 2001, 5- to 6-yr-old (N = 296) and 10- to 12-yr-old (N = 919) children and their parents were recruited from 19 state elementary schools in Melbourne, Australia. Children's PA was objectively assessed using accelerometers worn for 8 d. Sociodemographic and family structure information and time spent watching TV was collected via questionnaire completed by parents. RESULTS: ANCOVA revealed that, after controlling for socioeconomic status and age of child, boys without any siblings spent more minutes per day watching TV (153.2 +/- 71.3) compared with those who have siblings (129.0 +/- 64.4, P < 0.05). There were also significant differences in TV viewing time between boys with one sibling (125.5 +/- 59.9), two siblings (141.9 +/- 70.1), or three or more siblings (111.6 +/- 62.6, P < 0.001). Girls from single-parent families (145.7 +/- 85.1) spent significantly more minutes per day watching TV compared with girls from two-parent families (125.1 +/- 67.7, P < 0.05). Girls with siblings spent more minutes per day in PA (148.3 +/- 67.7) compared with those who were an only child (131.0 +/- 58.9, P < 0.05). There were significant interactions between parental status and having a sibling, with PA, and also with TV viewing for girls and between parental status and having a brother with PA for boys. There were also significant interactions between having an older sibling and child's sex with PA and between number of siblings and sex with TV viewing. CONCLUSIONS: Family structure may be an important source of influence on children's PA and TV viewing time. Aspects of family structure interact differently with PA and TV viewing, suggesting interventions may need to be tailored with consideration of the family structure of children.

Home health visits using a cable television network: user satisfaction.

There are about 1.5 million home patients who receive home health care (nurses visiting patients in their homes) in the US each year. In a significant proportion of these visits, hands-on care is not needed. Rather, the nurse needs to verify compliance with medication regimes, assess mental or emotional status, or check blood sugar levels, blood pressure and the like. Many of these activities might be handled by a nursing visit using interactive video to the patient's home, saving the nurse's time wasted in driving, finding parking, etc. A system for delivering home health care using interactive video has been piloted in the state of Kansas. Using the local cable television infrastructure for audio and video transmission, this system permits a nurse to see patients in their homes for a fraction of the cost of an on-site visit. This new method of delivering home health care is being evaluated with an ongoing study of utilization and user satisfaction. We conducted a prospective survey administered to home health nurses (n = 2) and homebound patients (n = 3) using a cable TV-mediated interactive video system, to assess utilization and user satisfaction with televideo-mediated home health care visits. One hundred and eighty-one patient questionnaires and 193 nurses questionnaires were completed. The average length of a visit was 15 minutes (range 1-91). All mean scores tabulated for the questions indicated strong nurse and patient satisfaction with the system. Participating nurses and clients were satisfied with the televideo encounters. The mean score for all questions was better than neutral. Recognizing that this was a pilot study, hampered by small numbers and subject to the inherent biases of a single institution study, the results support further investigation and implementation of this modality for home health care.
