HIV-prevention knowledge among illiterate and low-literate women in rural Amhara, Ethiopia

More than 85% of Ethiopia's population lives in rural areas and literacy levels in the country are relatively low. Despite this, little is known about levels of knowledge in regard to HIV/AIDS and condom use among illiterate and low-literate rural individuals. We conducted a cross-sectional study among 200 illiterate to semi-literate women, ages 13 to 24, from two rural communities in the Amhara region of northwestern Ethiopia. Nearly all the women had heard about HIV and AIDS. Among the illiterate individuals (n = 54), 24% did not know that HIV was the cause of AIDS and 48% did not know that HIV could be transmitted by sexual intercourse without a condom with an HIV-infected person. Among the same group, 59% did not know what a condom is. Literacy had a strong positive association with knowledge of HIV transmission and condoms. Thus, due to a generally higher level of literacy (grade 5-8 attainment), very young women (ages 13-20) had better knowledge of HIV transmission and condoms than did women ages 21-24 who by comparison were less literate. Given poor knowledge of HIV transmission and condoms among illiterate and low-literate women in Amhara, targeted HIV-prevention interventions are needed in this region.

Moving beyond a limited follow-up in cost-effectiveness analyses of behavioral interventions

BACKGROUND

Cost-effectiveness analyses of behavioral interventions typically use a dichotomous outcome criterion. However, achieving behavioral change is a complex process involving several steps towards a change in behavior. Delayed effects may occur after an intervention period ends, which can lead to underestimation of these interventions. To account for such delayed effects, intermediate outcomes of behavioral change may be used in cost-effectiveness analyses. The aim of this study is to model cognitive parameters of behavioral change into a cost-effectiveness model of a behavioral intervention.

METHODS

The cost-effectiveness analysis (CEA) of an existing dataset from an RCT in which an high-intensity smoking cessation intervention was compared with a medium-intensity intervention, was re-analyzed by modeling the stages of change of the Transtheoretical Model of behavioral change. Probabilities were obtained from the dataset and literature and a sensitivity analysis was performed.

RESULTS

In the original CEA over the first 12 months, the high-intensity intervention dominated in approximately 58% of the cases. After modeling the cognitive parameters to a future 2nd year of follow-up, this was the case in approximately 79%.

CONCLUSION

This study showed that modeling of future behavioral change in CEA of a behavioral intervention further strengthened the results of the standard CEA. Ultimately, modeling future behavioral change could have important consequences for health policy development in general and the adoption of behavioral interventions in particular.

Public participation in genomics research in the Netherlands: validating a measurement scale

Nowadays, new technologies, like genomics, cannot be developed without the support of the public. However, although interested, the public does not always actively participate in science issues when offered the opportunity via public participation activities. In a study aimed at validating a measurement scale, first, we investigated if public participation existed, and, secondly, we investigated how levels of public participation in genomics research varied among groups. Finally, we studied which factors predicted public participation. Results were based on a questionnaire with four subsamples. Results confirmed, first of all, the internal consistency of the measurement scale to assess levels of public participation. Secondly, the groups differed significantly with regard to their levels of participation in genomics research. Finally, the findings revealed that information-seeking behaviour, knowledge and education were main predictors of public participation, while interest, social involvement, and trust and influence had some influence together with age and gender.

The role of cognition in cost-effectiveness analyses of behavioral interventions

Background

Behavioral interventions typically focus on objective behavioral endpoints like weight loss and smoking cessation. In reality, though, achieving full behavior change is a complex process in which several steps towards success are taken. Any progress in this process may also be considered as a beneficial outcome of the intervention, assuming that this increases the likelihood to achieve successful behavior change eventually. Until recently, there has been little consideration about whether partial behavior change at follow-up should be incorporated in cost-effectiveness analyses (CEAs). The aim of this explorative review is to identify CEAs of behavioral interventions in which cognitive outcome measures of behavior change are analyzed.

Methods

Data sources were searched for publications before May 2011.

Results

Twelve studies were found eligible for inclusion. Two different approaches were found: three studies calculated separate incremental cost-effectiveness ratios for cognitive outcome measures, and one study modeled partial behavior change into the final outcome. Both approaches rely on the assumption, be it implicitly or explicitly, that changes in cognitive outcome measures are predictive of future behavior change and may affect CEA outcomes.

Conclusion

Potential value of cognitive states in CEA, as a way to account for partial behavior change, is to some extent recognized but not (yet) integrated in the field. In conclusion, CEAs should consider, and where appropriate incorporate measures of partial behavior change when reporting effectiveness and hence cost-effectiveness.

Online usability and patients with long-term conditions: a mixed-methods approach

BACKGROUND

To improve the information position of health care consumers and to facilitate decision-making behavior in health the Dutch ministry of Health commissioned the National Institute for Public Health and the Environment to develop, host and manage a public national health and care portal (www.kiesbeter.nl) on the Internet. The portal is used by over 4 million visitors in 2010. Among them, an increasing amount of patients that use the portal for information and decision making on medical issues, healthy living, health care providers and other topics.

OBJECTIVE

First objective is to examine what usability aspects of the portal kiesBeter.nl matter for chronic patients and their informal carers with regard to information seeking, self-management, decision making, on line health information and other variables. Second objective is to make evidence-based practical recommendations for usability improvement.

METHODS

An innovative combination of techniques (semi-structured interviews; eHealth Literacy scale; scenario-based study using think-aloud protocol and screen capture software; focus group) is used to study usability and on line information seeking behavior in a non random judgment sample of three groups of patients (N=21) with long-term medical conditions (arthritis, asthma and diabetes).

RESULTS

The search strategy mostly used (65%) by the relatively well-educated subjects is 'orienteering'. Users with long-term conditions and their carers expect tailored support from a national health portal, to help them navigate, search and find the detailed information they need. They encounter serious problems with these usability issues some of which are disease-specific. Patients indicate a need for personalized information. They report low impact on self-management and decision making. Overall judgment of usability is rated 7 on a Likert type 0-10 scale. Based on the outcomes recommendations could be formulated. These have led to major adaptations to improve usability.

LIMITATIONS

A non-representative composition of a small non random judgment sample does not permit generalization to other populations and cognitive bias cannot be quantified. However if mixed methods are applied valid conclusions can be drawn with regard to usability issues.

Why business modeling is crucial in the development of eHealth technologies

The impact and uptake of information and communication technologies that support health care are rather low. Current frameworks for eHealth development suffer from a lack of fitting infrastructures, inability to find funding, complications with scalability, and uncertainties regarding effectiveness and sustainability. These issues can be addressed by defining a better implementation strategy early in the development of eHealth technologies. A business model, and thus business modeling, help to determine such an implementation strategy by involving all important stakeholders in a value-driven dialogue on what the technology should accomplish. This idea also seems promising to eHealth, as it can contribute to the whole development of eHealth technology. We therefore suggest that business modeling can be used as an effective approach to supporting holistic development of eHealth technologies. The contribution of business modeling is elaborated in this paper through a literature review that covers the latest business model research, concepts from the latest eHealth and persuasive technology research, evaluation and insights from our prior eHealth research, as well as the review conducted in the first paper of this series. Business modeling focuses on generating a collaborative effort of value cocreation in which all stakeholders reflect on the value needs of the others. The resulting business model acts as the basis for implementation. The development of eHealth technology should focus more on the context by emphasizing what this technology should contribute in practice to the needs of all involved stakeholders. Incorporating the idea of business modeling helps to cocreate and formulate a set of critical success factors that will influence the sustainability and effectiveness of eHealth technology.

Cost-effectiveness of an intensive smoking cessation intervention for COPD outpatients

INTRODUCTION

To determine the cost-effectiveness of a high-intensity smoking cessation program (SmokeStop Therapy; SST) versus a medium-intensity treatment (Minimal Intervention Strategy for Lung patients [LMIS]) for chronic obstructive pulmonary disease outpatients.

METHODS

The cost-effectiveness analysis was based on a randomized controlled trial investigating the effectiveness of the SST compared with the LMIS with 12-month follow-up. The primary outcome measure was the cotinine-validated continuous abstinence rate based on intention to treat. A health care perspective was adopted, with outcomes assessed in terms of (incremental) additional quitters gained, exacerbations prevented, and hospital days prevented. Health care resource use, associated with smoking cessation, was collected at baseline and 12 months after the start of the interventions. Monte Carlo simulations were performed to evaluate the robustness of the results.

RESULTS

The average patient receiving SST generated €581 in health care costs, including the costs of the smoking cessation program, versus €595 in the LMIS. The SST is also associated with a lower average number of exacerbations (0.38 vs. 0.60) and hospital days (0.39 vs. 1) per patient and a higher number of quitters (20 vs. 9) at lower total costs. This leads to a dominance of the SST compared with the LMIS.

CONCLUSIONS

The high-intensive SST is more cost-effective than the medium-intensive LMIS after 1 year. This is associated with cost savings per additional quitter, prevented exacerbations, and hospital days at lower or equal costs.

A holistic framework to improve the uptake and impact of eHealth technologies

BACKGROUND

Many eHealth technologies are not successful in realizing sustainable innovations in health care practices. One of the reasons for this is that the current development of eHealth technology often disregards the interdependencies between technology, human characteristics, and the socioeconomic environment, resulting in technology that has a low impact in health care practices. To overcome the hurdles with eHealth design and implementation, a new, holistic approach to the development of eHealth technologies is needed, one that takes into account the complexity of health care and the rituals and habits of patients and other stakeholders.

OBJECTIVE

The aim of this viewpoint paper is to improve the uptake and impact of eHealth technologies by advocating a holistic approach toward their development and eventual integration in the health sector.

METHODS

To identify the potential and limitations of current eHealth frameworks (1999-2009), we carried out a literature search in the following electronic databases: PubMed, ScienceDirect, Web of Knowledge, PiCarta, and Google Scholar. Of the 60 papers that were identified, 44 were selected for full review. We excluded those papers that did not describe hands-on guidelines or quality criteria for the design, implementation, and evaluation of eHealth technologies (28 papers). From the results retrieved, we identified 16 eHealth frameworks that matched the inclusion criteria. The outcomes were used to posit strategies and principles for a holistic approach toward the development of eHealth technologies; these principles underpin our holistic eHealth framework.

RESULTS

A total of 16 frameworks qualified for a final analysis, based on their theoretical backgrounds and visions on eHealth, and the strategies and conditions for the research and development of eHealth technologies. Despite their potential, the relationship between the visions on eHealth, proposed strategies, and research methods is obscure, perhaps due to a rather conceptual approach that focuses on the rationale behind the frameworks rather than on practical guidelines. In addition, the Web 2.0 technologies that call for a more stakeholder-driven approach are beyond the scope of current frameworks. To overcome these limitations, we composed a holistic framework based on a participatory development approach, persuasive design techniques, and business modeling.

CONCLUSIONS

To demonstrate the impact of eHealth technologies more effectively, a fresh way of thinking is required about how technology can be used to innovate health care. It also requires new concepts and instruments to develop and implement technologies in practice. The proposed framework serves as an evidence-based roadmap.

Factors influencing the use of a Web-based application for supporting the self-care of patients with type 2 diabetes: a longitudinal study

BACKGROUND

The take-up of eHealth applications in general is still rather low and user attrition is often high. Only limited information is available about the use of eHealth technologies among specific patient groups.

OBJECTIVE

The aim of this study was to explore the factors that influence the initial and long-term use of a Web-based application (DiabetesCoach) for supporting the self-care of patients with type 2 diabetes.

METHODS

A mixed-methods research design was used for a process analysis of the actual usage of the Web application over a 2-year period and to identify user profiles. Research instruments included log files, interviews, usability tests, and a survey.

RESULTS

The DiabetesCoach was predominantly used for interactive features like online monitoring, personal data, and patient-nurse email contact. It was the continuous, personal feedback that particularly appealed to the patients; they felt more closely monitored by their nurse and encouraged to play a more active role in self-managing their disease. Despite the positive outcomes, usage of the Web application was hindered by low enrollment and nonusage attrition. The main barrier to enrollment had to do with a lack of access to the Internet (146/226, 65%). Although 68% (34/50) of the enrollees were continuous users, of whom 32% (16/50) could be defined as hardcore users (highly active), the remaining 32% (16/50) did not continue using the Web application for the full duration of the study period. Barriers to long-term use were primarily due to poor user-friendliness of the Web application (the absence of "push" factors or reminders) and selection of the "wrong" users; the well-regulated patients were not the ones who could benefit the most from system use because of a ceiling effect. Patients with a greater need for care seemed to be more engaged in long-term use; highly active users were significantly more often medication users than low/inactive users (P = .005) and had a longer diabetes duration (P = .03).

CONCLUSION

Innovations in health care will diffuse more rapidly when technology is employed that is simple to use and has applicable components for interactivity. This would foresee the patients' need for continuous and personalized feedback, in particular for patients with a greater need for care. From this study several factors appear to influence increased use of eHealth technologies: (1) avoiding selective enrollment, (2) making use of participatory design methods, and (3) developing push factors for persistence. Further research should focus on the causal relationship between using the system's features and actual usage, as such a view would provide important evidence on how specific technology features can engage and captivate users.

Effectiveness of a Web-based intervention aimed at healthy dietary and physical activity behavior: a randomized controlled trial about users and usage

Background

Recent studies have shown the potential of Web-based interventions for changing dietary and physical activity (PA) behavior. However, the pathways of these changes are not clear. In addition, nonusage poses a threat to these interventions. Little is known of characteristics of participants that predict usage.

Objective

In this study we investigated the users and effect of the Healthy Weight Assistant (HWA), a Web-based intervention aimed at healthy dietary and PA behavior. We investigated the value of a proposed framework (including social and economic factors, condition-related factors, patient-related factors, reasons for use, and satisfaction) to predict which participants are users and which participants are nonusers. Additionally, we investigated the effectiveness of the HWA on the primary outcomes, self-reported dietary and physical activity behavior.

Methods

Our design was a two-armed randomized controlled trial that compared the HWA with a waiting list control condition. A total of 150 participants were allocated to the waiting list group, and 147 participants were allocated to the intervention group. Online questionnaires were filled out before the intervention period started and after the intervention period of 12 weeks. After the intervention period, respondents in the waiting list group could use the intervention. Objective usage data was obtained from the application itself.

Results

In the intervention group, 64% (81/147) of respondents used the HWA at least once and were categorized as “users.” Of these, 49% (40/81) used the application only once. Increased age and not having a chronic condition increased the odds of having used the HWA (age: beta = 0.04, P = .02; chronic condition: beta = 2.24, P = .003). Within the intervention group, users scored better on dietary behavior and on knowledge about healthy behavior than nonusers (self-reported diet: χ²₂ = 8.4, P = .02; knowledge: F_1,125 = 4.194, P = .04). Furthermore, users underestimated their behavior more often than nonusers, and nonusers overestimated their behavior more often than users (insight into dietary behavior: χ²₂ = 8.2, P = .02). Intention-to-treat analyses showed no meaningful significant effects of the intervention. Exploratory analyses of differences between pretest and posttest scores of users, nonusers, and the control group showed that on dietary behavior only the nonusers significantly improved (effect size r = −.23, P = .03), while on physical activity behavior only the users significantly improved (effect size r = −.17, P = .03).

Conclusions

Respondents did not use the application as intended. From the proposed framework, a social and economic factor (age) and a condition-related factor (chronic condition) predicted usage. Moreover, users were healthier and more knowledgeable about healthy behavior than nonusers. We found no apparent effects of the intervention, although exploratory analyses showed that choosing to use or not to use the intervention led to different outcomes. Combined with the differences between groups at baseline, this seems to imply that these groups are truly different and should be treated as separate entities.

Reaching the hearts and minds of illiterate women in the Amhara highland of Ethiopia: Development and pre-testing of oral HIV/AIDS prevention messages

In the style of radio programmes, we developed three episodes of audio HIV prevention education for illiterate women in Ethiopia. We used social-oriented presentation formats, such as discussion between women on HIV prevention, and expert-oriented presentation formats, such as an interview with a male doctor. The aim of this study was to assess the relation between evaluation of presentation formats and overall liking of episodes, which is important for persuasive effects. Thirty women from rural Amhara listened to the episodes and, after listening, female data collectors interviewed the women on evaluation of presentation formats, overall liking of episodes, identification with the characters and convincingness. Evaluation of social-oriented presentation formats was strongly related to overall liking of episodes, but evaluation of expert-oriented presentation formats was not. This relation was mediated through convincingness and not through identification. We conclude that social-oriented presentation formats make messages more convincing and, consequently, improve overall liking and persuasive impact.

Effects of a theory-based audio HIV/AIDS intervention for illiterate rural females in Amhara, Ethiopia

In Ethiopia the level of illiteracy in rural areas is very high. In this study, we investigated the effects of an audio HIV/AIDS prevention intervention targeted at rural illiterate females. In the intervention we used social-oriented presentation formats, such as discussion between similar females and role-play. In a pretest and posttest experimental study with an intervention group (n = 210) and control group (n = 210), we investigated the effects on HIV/AIDS knowledge and social cognitions. The intervention led to significant and relevant increases in HIV/AIDS knowledge, self-efficacy, perceived vulnerability to HIV/AIDS infection, response efficacy of condoms and condom use intention. In the intervention group, self-efficacy at posttest was the main determinant of condom use intention, with also a significant contribution of vulnerability. We conclude that audio HIV/AIDS prevention interventions can play an important role in empowering rural illiterate females in the prevention of HIV/AIDS.

Women's opinions about attending for breast cancer screening: Stability of cognitive determinants during three rounds of screening

OBJECTIVES

To examine the stability of beliefs and intentions towards repeat attendance at breast cancer screening, using the Theory of Planned Behaviour. The aims of the study were to examine whether and how cognitions changed in the course of the programme, and whether intentions that were assessed proximally were better predictors of behaviour than those assessed distally.

DESIGN AND METHODS

A total of 2,657 women filled out a baseline questionnaire (T(1)), 2 months after being invited for an initial mammogram in the Dutch Breast Cancer Screening Programme. Actual attendance data in the second and third screening rounds were subsequently collected and follow-up questionnaires were sent to parts of the sample at four points in time: shortly before (T(2)) and after (T(3)) the second screening round, and shortly before (T(4)) and after (T(5)) the third screening round.

RESULTS

Only minor changes in beliefs and intentions were found. In the assessments shortly before screening, women were somewhat less positive about attending than in the assessments shortly after screening. Throughout the course of the programme, women's opinions about attending remained positive. In fact, women became somewhat more convinced that they were vulnerable to getting breast cancer, and that participating in screening was beneficial to them. Actual attendance in subsequent rounds of screening was higher than expected. Proximal beliefs and intentions were only slightly more predictive of actual behaviour than distal beliefs.

CONCLUSIONS

In organized breast cancer screening, beliefs and intentions remain positive and rather stable. Although our results should be interpreted with caution, due to little variation in behaviour, they suggest that the gap between intentions and behaviour could not be substantially reduced by proximal assessment of determinants.

Patient use and compliance with medical advice delivered by a web-based triage system in primary care

We studied a web-based triage system which was accessible to the general public in the Netherlands. In a retrospective analysis we investigated the type of complaints that were submitted and the kind of advice provided. Over a period of 15 months, 13,133 different people began using the web-based triage system and 3812 patients went right through the triage process to the end. The most frequent complaints were common cold symptoms, such as cough and a sore throat (22%), itch problems (13%), urinary complaints (12%), diarrhoea (10%), headache (8%) and lower back pain (8%). Most commonly, the system generated the advice to contact a doctor (85%) and in 15% of the cases the system provided fully automated, problem-tailored, self-care advice. A total of 192 patients participated in a prospective study and completed an online survey immediately after the delivery of advice. A follow-up questionnaire on actual compliance was completed by 35 patients. Among these, 20 (57%) had actually complied with the advice provided by the system. A regression analysis revealed that intention to comply was strongly related to actual compliance. In turn, intention to comply was strongly related to attitude towards the advice (P < 0.001). Web-based triage can contribute to a more efficient primary care system, because it facilitates the gatekeeper function.

Evaluation of a web-based lifestyle coach designed to maintain a healthy bodyweight

We evaluated a web-based intervention, the Healthy Weight Assistant (HWA), which was designed to help people with a healthy bodyweight, or those who are slightly overweight, to achieve and maintain a healthy weight. Four evaluation methods were used: (1) pre- and post-test questionnaires; (2) real time usability-tests; (3) log-file analysis; (4) qualitative analysis of forum posts, email messages and free-text responses in the questionnaires. A total of 703 respondents received access to the HWA. Six weeks after receiving access, 431 respondents completed a second questionnaire. The enthusiastic responses showed that many people were interested in using an interactive online application to support achieving and maintaining a healthy weight. The preliminary results suggest that improvements with respect to motivation may lead to large effects, yet require only small changes in the design of the HWA. Sending automatic tailored reminders may enhance motivation to keep using the application. Motivation to change behaviour may be enhanced by emphasizing goal setting and visualizing progress.

Patient-initiated online support groups: motives for initiation, extent of success and success factors

We studied the success and success factors of online support groups (OSGs) for patients, and the motives and goals of people who start such groups. We interviewed 23 webmasters of OSGs for patients with breast cancer, fibromyalgia and arthritis. The majority were women (n = 20) and most were patients (n = 21). Analysis of the interviews revealed that webmasters had altruistic and intrinsic motives for initiating an online support group. They defined success as the fulfilment of the goals they had in mind when they initiated their groups. To be able to make a group successful, decisions about its organization and management need to be coherent with these goals. Most webmasters stressed that promoting the group, keeping it alive and moderating the messages were vital success factors during the evolution stage. Management of the OSGs took up much of the webmasters' time and energy. On average webmasters were occupied with the group for 10-15 hours a week. Our study provides an overview of the pros and cons of differing decisions that have to be made when initiating an OSG.

Experiences and attitudes of Dutch rheumatologists and oncologists with regard to their patients' health-related Internet use

The objective of this study is to explore the experiences and attitudes of rheumatologists and oncologists with regard to their patients’ health-related Internet use. In addition, we explored how often physicians referred their patients to health-related Internet sites. We sent a questionnaire to all the rheumatologists and oncologists in the Netherlands. The questionnaire included questions concerning demographics, experiences with patients’ health-related Internet use, referral behavior, and attitudes to the consequences of patients’ health-related Internet use (for patients themselves, the physician-patient relationship and the health care). The response rate was 46% (N = 238). Of these respondents, 134 practiced as a rheumatologist and 104 as an oncologist. Almost all physicians encountered their patients raising information from the Internet during a consultation. They were not, however, confronted with their patients’ health-related Internet use on a daily basis. Physicians had a moderately positive attitude towards the consequences of patients’ health-related Internet use, the physician-patient relationship and the health care. Oncologists were significantly less positive than rheumatologists about the consequences of health-related Internet use. Most of the physicians had never (32%) or only sometimes (42%) referred a patient to a health-related Internet site. Most physicians (53%) found it difficult to stay up-to-date with reliable Internet sites for patients. Physicians are moderately positive about their patients’ health-related Internet use but only seldom refer them to relevant sites. Offering an up-to-date site with accredited websites for patients might help physicians refer their patients.

A study of a Dutch online decision aid for parents of children with ADHD

During a three-month study period, visitors to an online decision aid (DA) for attention deficit hyperactivity disorder (ADHD) were invited to complete an online questionnaire before and after working through the DA. Some 75,000 unique visitors found their way to the page on DAs, although fewer than 1 in 10 visited the DA for ADHD, staying there for about six minutes on average and using 8–9 clicks to navigate. A total of 195 people completed the first questionnaire (a response rate of about 3%). Only 12 of the respondents to the first questionnaire (6%) completed the second questionnaire. There was no significant effect of the DA as measured by three decisional outcome measures. Respondents moderately appreciated the information received. Even though the DA was constructed according to evidence-based guidelines and International Patient Decision Aids Standards wherein expert and patient involvement are assured, these preliminary results suggest that the online DA for ADHD needs further work to support the decision-making process of parents with regard to the most appropriate treatment for their child.

Evaluation of the use of an "ask-the-expert" e-consultation service for support on health-related requests

E-consultation in health care can be used to respond to an increasing demand for care by offering support on health-related requests. In this study we evaluated the use of an "ask-the-expert" e-consultation service in order to assess whether the service is efficient and useful. A content analysis of e-mail exchange between clients and online health professionals was performed to gain insight in the purposes of use of the service. Our findings show that the e-consultation service was used for health requests on not urgent, minor ailments. Clients asked for health information to increase knowledge on the cause of their injury or disease, its consequences, possible self-care solutions and treatment options. Decision support on assessing the necessity to visit a doctor for a certain health problem was another important reason to use the service. We believe that web-based triage systems could be used to more easily assess whether certain symptoms need to be investigated.

Usage and effect of a web-based intervention for the prevention of overweight; a RCT

Web-based interventions can be effective in changing behaviour of people faced with health problems. However, it is unclear whether they are effective in preventing health problems like overweight. The aim of this study was to investigate usage and effectiveness of the Healthy Weight Assistant (HWA), a web-based application to increase healthy behaviour in adults with a healthy weight or slight overweight, by means of a Randomised Controlled Trial (RCT). 297 respondents were randomly assigned to the intervention (n=147) or the waiting list group (n=150). The intervention group received access to the intervention for 12 weeks. At pre- and post-test we measured dietary and physical activity behaviour (primary outcomes) and BMI, knowledge, attitude, self-efficacy, subjective behaviour and insight in behaviour (secondary outcomes). All participants, regardless of group, show improvement in healthy behaviour and subjective assessment of healthy behaviour. People who are older, score higher on dietary behaviour and under-estimate their dietary behaviour are more likely to use the HWA. Using the HWA leads to improvement in physical activity behaviour and insight in physical activity behaviour.

Health-related Internet use by patients with somatic diseases: frequency of use and characteristics of users

The aim of this study was to explore the percentage of Dutch patients using the Internet to search for information about their illness. In addition, we studied patients' usage of health-related Internet applications, such as online patient support groups. The final objective of this study was to explore which demographic, health and psychological characteristics are related to patients' health-related Internet use. In order to answer these research questions we sent a written questionnaire to a representative sample of patients with breast cancer, rheumatoid arthritis and fibromyalgia. The overall total response rate was 69% (N = 679). In total, 52% of the patients used the Internet to search for information about their illness. However, only 15% of the respondents had ever read along with an online patient support group. An even smaller proportion of the patients (4%) had send postings to such a group. Online communication with health professionals was not commonly practiced. A younger age, a higher education and employment appeared to be the only significant predictors of patients' health-related Internet use. Patients' health-related Internet use could not be predicted by health and psychological characteristics. Although, about half of the patients made use of the Internet for health-related reasons, mostly their health-related Internet use was restricted to seeking information about their illness.

[Dementia and technology. A study of technology interventions in the healthcare for dementia patients and their caregivers]

PURPOSE

To explore the possibilities for IT interventions in care of older persons with dementia.

METHOD

Inventory of international and national studies on implemented technology interventions for the care of persons with dementia and their caregivers. Three categories of technology are distinguished: (1) help with symptoms of dementia (2) social contact and company for the patient, and (3) health monitoring and safety.

RESULTS

Eighteen international and eight national studies are included. The first results of the effects of technology interventions for patients with dementia look promising. Evidence exists for significant improvements as to the quality of life and effects on behaviour (such as less falling). The caregivers and healthcare professionals are satisfied with the usability of the technology. The purchase and user costs, however, are often too high. The labour satisfaction of healthcare professionals in relation to the use of technology has rarely been studied.

CONCLUSION

Although technology can improve the ability to cope with certain consequences of dementia, the effects of technology for dementia patients, caregivers and healthcare professionals has not yet been extensively studied. Further research may focus on effects of technology for people with dementia and their caregivers as to their quality of life, feeling of safety and work satisfaction, respectively.

Participation in online patient support groups endorses patients' empowerment

OBJECTIVE

Although much has been expected of the empowering effect of taking part in online patient support groups, there is no direct evidence thus far for the effects of participation on patient empowerment. Hence our exploring to what extent patients feel empowered by their participation in online support groups, and which processes that occur in these groups are related to the empowering outcomes.

METHODS

An online questionnaire was completed by 528 individuals who were active in online groups for patients with breast cancer, fibromyalgia and arthritis.

RESULTS

The respondents felt empowered in several ways by their participation. The empowering outcomes that were experienced to the strongest degree were 'being better informed' and 'enhanced social well-being'. No significant differences in empowering outcomes between diagnostic groups were found. The empowering outcomes could only be predicted in a modest way by the processes that took place in the online support groups.

CONCLUSION

This study indicates that participation in online support groups can make a valuable contribution to the empowerment of patients.

PRACTICE IMPLICATIONS

Health care providers should acquaint their patients with the existence of online support groups and with the benefits that participation in these groups can offer.

Self-reported differences in empowerment between lurkers and posters in online patient support groups

BACKGROUND

Patients who visit online support groups benefit in various ways. Results of our earlier study indicated that participation in online support groups had a profound effect on the participants' feelings of "being empowered." However, most studies of online patient support groups have focused on the members of these groups who actively contribute by sending postings (posters). Thus far, little is known about the impact for "lurkers" (ie, those who do not actively participate by sending postings).

OBJECTIVE

In the present study, we explored if lurkers in online patient support groups profit to the same extent as posters do.

METHODS

We searched the Internet with the search engine Google to identify all Dutch online support groups for patients with breast cancer, fibromyalgia, and arthritis. Invitations to complete an online survey were sent out by the owners of 19 groups. In the online questionnaire, we asked questions about demographic and health characteristics, use of and satisfaction with the online support group, empowering processes, and empowering outcomes. The online questionnaire was completed by 528 individuals, of which 109 (21%) identified themselves as lurkers.

RESULTS

Lurkers (mean age 47 years) were slightly older than active participants (mean age 43 years, P = .002), had a shorter disease history (time since diagnosis 3.7 years vs 5.4 years, P = .001), and reported lower mental well-being (SF 12 subscore 37.7 vs 40.5, P = .004). No significant differences were found in other demographic variables. Posters indicated visiting the online support groups significantly more often for social reasons, such as curiosity about how other members were doing, to enjoy themselves, as a part of their daily routine (all P < .001), and because other members expected them to be there (P = .003). Lurkers and posters did not differ in their information-related reasons for visiting the online support group. Lurkers were significantly less satisfied with the online support group compared to posters (P < .001). With regard to empowering processes such as "exchanging information" and "finding recognition," lurkers scored significantly lower than posters. However, lurkers did not differ significantly from posters with regard to most empowering outcomes, such as "being better informed," "feeling more confident in the relationship with their physician," "improved acceptance of the disease," "feeling more confident about the treatment," "enhanced self-esteem," and "increased optimism and control." The exception was "enhanced social well-being," which scored significantly lower for lurkers compared to posters (P < .001).

CONCLUSION

Our study revealed that participation in an online support group had the same profound effect on lurkers' self-reported feelings of being empowered in several areas as it had on posters. Apparently, reading in itself is sufficient to profit from participation in an online patient support group.

Evaluation of internet-based technology for supporting self-care: problems encountered by patients and caregivers when using self-care applications

BACKGROUND

Prior studies have shown that many patients are interested in Internet-based technology that enables them to control their own care. As a result, innovative eHealth services are evolving rapidly, including self-assessment tools and secure patient-caregiver email communication. It is interesting to explore how these technologies can be used for supporting self-care.

OBJECTIVE

The aim of this study was to determine user-centered criteria for successful application of Internet-based technology used in primary care for supporting self-care.

METHODS

We conducted scenario-based tests combined with in-depth interviews among 14 caregivers and 14 patients/consumers to describe the use of various self-care applications and the accompanying user problems. We focused on the user-friendliness of the applications, the quality of care provided by the applications, and the implementation of the applications in practice.

RESULTS

Problems with the user-friendliness of the self-care applications concerned inadequate navigation structures and search options and lack of feedback features. Patients want to retrieve health information with as little effort as possible; however, the navigation and search functionalities of the applications appeared incapable of handling patients' health complaints efficiently. Among caregivers, the lack of feedback and documentation possibilities caused inconvenience. Caregivers wanted to know how patients acted on their advice, but the applications did not offer an adequate feedback feature. Quality of care problems were mainly related to insufficient tailoring of information to patients' needs and to efficiency problems. Patients expected personalized advice to control their state of health, but the applications failed to deliver this. Language (semantics) also appeared as an obstacle to providing appropriate and useful self-care advice. Caregivers doubted the reliability of the computer-generated information and the efficiency and effectiveness of secure email consultation. Legal or ethical issues with respect to possible misuse of email consultation also caused concerns. Implementation problems were mainly experienced by caregivers due to unclear policy on email consultation and the lack of training for email consultations.

CONCLUSIONS

Patients' and caregivers' expectations did not correspond with their experiences of the use of the Internet-based applications for self-care. Patients thought that the applications would support them in solving their health problems. Caregivers were more reserved about the applications because of medico-legal concerns about misuse. However, the applications failed to support self-care because eHealth is more than just a technological intervention. The design of the applications should include a way of thinking about how to deliver health care with the aid of technology. The most powerful application for self-care was secure email consultation, combined with a suitable triage mechanism to empower patients' self-awareness. Future research should focus on the effectiveness of such Web-based triage mechanisms for medical complaints and on the development of interactive features to enhance patients' self-care.

Empowering processes and outcomes of participation in online support groups for patients with breast cancer, arthritis, or fibromyalgia

Ever since the rise of online support groups it has been presumed that there is an empowering effect from patients' participating in these groups, despite a lack of evidence to back up this assumption. In this study we explored if, and in which ways, patients feel empowered by participation. Additionally, we studied which empowering and disempowering processes occur as a result of taking part in these groups. To accomplish this aim, we interviewed 32 participants of online support groups. This analysis revealed the following empowering processes: exchanging information, encountering emotional support, finding recognition, sharing experiences, helping others, and amusement. Disempowering processes were mentioned far less often. Empowering outcomes mentioned were being better informed; feeling confident in the relationship with their physician, their treatment, and their social environment; improved acceptance of the disease; increased optimism and control; enhanced self-esteem and social well-being; and collective action. This article demonstrates that participation in online support groups can make a valuable contribution to the emergence of empowered patients.

Monitoring women's experiences during three rounds of breast cancer screening: results from a longitudinal study

OBJECTIVES

(a) To monitor experiences of women during three successive rounds of breast screening; (b) to examine the impact of previous experiences (obtained either immediately after the latest mammogram or shortly before the subsequent one) on reattendance; and (c) to examine which factors are associated with the experience of pain and distress during screening.

SETTING

The Dutch Breast Cancer Screening Programme

METHODS

2657 women completed a baseline measurement (response rate 67%) about 8 weeks after they had been invited for an initial mammogram (T(1)). Actual participation data of these women in the second and third rounds of screening were collected. Follow up questionnaires were sent to subgroups of the sample at different times: shortly before the second screening (T(2); response rate 86%), shortly after the second screening (T(3); response rate 85%), shortly before the third screening (T(4); response rate 80%), and shortly after the third screening (T(5); response rate 78%).

RESULTS

Most women were satisfied with the first screening round and remained positive about subsequent screens. Although pain and anxiety were not uncommon, only a few (10%-15%) experienced moderate or severe levels of distress or pain. Experiences were relatively stable: women who experienced pain in the first screen were more likely to experience pain in subsequent screens (r values from 0.39 to 0.50). Fear of breast cancer was associated with increased distress related to mammography and, to a lesser extent, with increased pain during the mammography. Evidence was found for a relief effect: women were more positive about their previous screen when asked shortly after this screen, than when asked just before the subsequent one. Previous experiences (obtained either proximally or distally) were only slightly predictive for future attendance.

CONCLUSION

Experiences during mammography are fairly stable. Negative experiences were generally not a reason to drop out of the programme.

Does mammographic screening and a negative result affect attitudes towards future breast screening?

OBJECTIVES

To investigate the impact of an experience of a benign mammographic result on intention to seek medical help immediately in the case of breast abnormalities, and on intentions and thoughts about future participation in screening.

SETTING

The Dutch Breast Cancer Screening Programme for women aged 50-69.

METHODS

Subjects were women who were invited for an initial breast examination: 223 women filled out a questionnaire about 10 days before and about 6 weeks after their initial breast examination. To be able to control for possible test effects, another group of 293 women filled out a questionnaire only after mammography. Changes in thoughts and intentions were examined.

RESULTS

Most women were very satisfied with the course of their initial breast examination, although pain or discomfort was often mentioned. No clues to suggest false reassurance were found: more than 99% of the women would consider the possibility of breast cancer if they felt a lump in one of their breasts. In such a situation, most women intended to seek medical help within a week. These variables were not influenced by the experience of mammography with a benign result. In general, women were very positive about (repeat) participation, both before and after screening. After screening, the average woman perceived fewer costs in participating, and perceived her own ability to engage in future screening as higher. However, the experience of pain and anxiety during the initial screening did lead to reverse effects. Women who were less satisfied about their treatment by the staff were more likely to change their intentions to reparticipate in a negative way.

CONCLUSIONS

As, in general, women became more positive about regular participation after they had attended breast cancer screening, efforts to improve first round attendance must be continued. At the same time, the screening organisations must continue to prioritise the high level of client friendliness throughout the screening. No evidence for detrimental effects of screening through false reassurance among participants was found.

Behavioural effect of self-treatment guidelines in a self-management program for adults with asthma

To assess the efficacy of self-management programs it is important to know what behavioural changes take place. This paper assesses whether including self-treatment guidelines (action plans) in a self-management program for adult asthmatics, leads to greater behavioural changes than a program without these guidelines. Patients were randomised into a self-treatment group (n=123) or an active control group (n=122). All subjects received self-management training. Discussed topics included the pathophysiology of asthma, medication and side-effects, triggers, symptoms, smoking, physical exercise, and compliance. The only difference was that the self-treatment group received instructions about self-treatment of exacerbations and the control group did not. At 1 year of follow-up asthma-specific self-efficacy expectancies, outcome expectancies, and asthma-specific knowledge improved significantly in all patients. Only self-treatment group patients demonstrated favourable changes in generalised self-efficacy, social support, and self-treatment and self-management behaviour, in case of a hypothetical scenario of a slow-onset exacerbation. We conclude that our self-management program is effective in changing the behavioural variables, and including self-treatment guidelines (action plans) has added benefit.

Benefit from the inclusion of self-treatment guidelines to a self-management programme for adults with asthma

This study assessed the long-term efficacy of adding self-treatment guidelines to a self-management programme for adults with asthma. In this prospective randomized controlled trial, 245 patients with stable, moderate to severe asthma were included. They were randomized into a self-treatment group (group S) and a control group (group C). Both groups received self-management education. Additionally, group S received self-treatment guidelines based on peak expiratory flow (PEF) and symptoms. Outcome parameters included: asthma symptoms, quality of life, pulmonary function, and exacerbation rate. The 2-yr study was completed by 174 patients. Both groups showed an improvement in the quality of life of 7%. PEF variability decreased by 32% and 29%, and the number of outpatient visits by 25% and 18% in groups S and C, respectively. No significant differences in these parameters were found between the two groups. After 1 yr, patients in both groups perceived better control of asthma and had more self-confidence regarding their asthma. The latter improvements were significantly greater in group S as compared to group C. There were no other differences in outcome parameters between the groups. Individual self-treatment guidelines for exacerbations on top of a general self-management programme does not seem to be of additional benefit in terms of improvements in the clinical outcome of asthma. However, patients in the self-treatment group had better scores in subjective outcome measures such as perceived control of asthma and self-confidence than patients in the control group.

Effectiveness of a minimal contact smoking cessation program for Dutch general practitioners: a randomized controlled trial

BACKGROUND

Until recently, Dutch general practitioners contributed little to tobacco control. This is due to several factors, among which is the lack of a feasible intervention program for adult smokers. Such a minimal contact behavioral intervention, using the Stage-of-Change concept, is now available. Effectiveness was tested in a randomized trial.

METHOD

Twenty-two general practitioners and their practice assistants were trained in applying the program. In all, 530 smoking patients were enrolled, randomly assigned to either the intervention or the usual treatment condition. Analysis of treatment effects was performed with logistic regression analysis. In a backward stepwise procedure confounding effects of baseline differences were eliminated.

RESULTS

At 12-month follow-up, self-reported abstinence rates (including nonrespondents as smokers) differed significantly between intervention subjects and controls: 13.4 vs 7.3% point prevalence (odds ratio 1.51, P < 0.05). An analysis of consecutive abstinence, defined as being abstinent at both 6- and 12-month follow-up, showed that 8.2% of the intervention group compared to 3.1% of the controls had sustained abstinence for more than 6 months (odds ratio 3.04, P < 0.001).

CONCLUSIONS

Results indicate that an effective smoking cessation program for use in Dutch general practice, already shown to be feasible, is now available. Outcomes are generally consistent with recent international literature.

Multiple inhalers confuse asthma patients

This study investigated the influence of the use of different types of inhalers on the adequacy of inhalation technique among adult asthmatics. Three hypotheses were tested: first, patients using only one type of inhaler will demonstrate adequate inhalation technique more often than those with two or more types. Secondly, patients using a combination of dry powder inhalers (DPIs) will demonstrate correct inhalation technique more often than those using the combination of a metered dose inhaler (MDI) and a DPI. Thirdly, some inhalers or combinations of inhalers are more prone to erroneous inhalation technique than others. Adult outpatients with asthma who regularly used inhaled steroid therapy (n=321) participated in the study. The inhalers investigated were MDIs on the one hand, and the DPIs Turbuhaler, Diskhaler, Cyclohaler, Inhaler Ingelheim and Rotahaler on the other. Of 208 adult asthmatics with only one inhaler, 71% made no inhalation errors versus 61% of 113 patients with two or more different inhalers. Of patients with a combination of DPIs 68% performed all essential checklist items correctly, versus 54% of patients with the combination of "regular" MDI and DPI. Patients using only the Diskhaler made fewest errors. Whenever possible, only one type of inhaler should be prescribed. If a combination is unavoidable, combinations of DPIs are preferable to MDI and DPI. The Diskhaler seems to be the most foolproof device.

Development of a needs assessment system in rehabilitation

The aim of this project was to develop a standardized, valid and reliable instrument for determining needs of patients and quality of care as perceived by patients. A questionnaire was constructed based upon the Service Quality Model. This model, patient expectations and experiences all play an important role in the questionnaire. The questionnaire contains a general part which includes ten determinants of care, the information the patient got and the perceived quality of care in general. The questionnaire also contains a specific part which includes questions about the actual care for diagnosis related problems. Twenty-four spinal cord injured patients, staying at a Dutch rehabilitation centre, participated in this study. It is concluded that with the developed questionnaire the perceived quality of care according to the Service Quality Model can be assessed. Major contributions of the questionnaire to rehabilitation care will be its ability to highlight patient needs related to identified symptoms, and to provide a tool to signal aspects in the organization that can be improved. Thus it becomes a tool for quality management. Recommendations have been made for further research to make future use of the questionnaire in other settings and populations possible.

Inhalation technique of 166 adult asthmatics prior to and following a self-management program

Self-management of asthma and self-treatment of exacerbations are considered important in the treatment of asthma. For successful self-treatment, medication has to be inhaled correctly, but the percentage of patients inhaling effectively varies widely. As part of a self-management program we checked and corrected inhalation technique. This paper addresses differences among inhalers in relation to patient characteristics and the effect of instruction, 1 year after enrollment. Maneuvers that are essential for adequate inhalation were identified. When errors in inhalation technique were observed, patients were instructed in the correct use of their devices. One year later, inhalation technique was checked again. Only patients who used the same inhaler throughout the entire study period were analyzed. Of the 245 adult asthmatic patients who were enrolled in the self-management program, 166 used the same inhaler throughout the study period. One hundred twenty patients (72%) performed all key items correctly at baseline and this increased to 80% after 1 year. At follow-up, older patients were less likely to demonstrate a perfect inhalation. Patients with a Diskhaler made fewest errors. Adjustment for differences in patient characteristics did not significantly change the results. Because many patients with asthma use their inhaler ineffectively, there is a need to know which inhaler leads to fewest errors. Diskhaler was nominated by this study. When patients are not able to demonstrate adequate inhalation technique in a "tranquil" setting, it is doubtful that they can do so when they experience an exacerbation. Therefore, inhalation instruction should be considered an essential ingredient, not only of self-management programs, but also of asthma patient care in general.

Medical opinions, beliefs and prescription of orthopaedic footwear: a survey of Dutch orthopaedists and rehabilitation practitioners

OBJECTIVES

To get insight into medical opinions about the use of orthopaedic footwear and the medical and social factors related to the prescription of orthopaedic footwear by orthopaedists and rehabilitation practitioners.

METHODS

In this study 85 orthopaedists and 96 rehabilitation practitioners filled out a questionnaire measuring perceived desirability of prescribing orthopaedic footwear in specific medical conditions, the perceived advantages of orthopaedic footwear, the perceived disadvantages of orthopaedic footwear, the attitude to orthopaedic footwear and satisfaction with the co-operation with the pedorthist. Clinicians were asked to estimate their referral rate of orthopaedic footwear.

RESULTS

Orthopaedists and rehabilitation practitioners agree that the prescription of orthopaedic footwear should be considered in the case of rheumatoid arthritis, amputation of the foot and diabetic foot and not be considered in the case of sprain and back pain. In the case of hallux valgi, dermatological problems and clavus (severe corn) a reticent prescription policy seems to be the optimal choice. In the other medical conditions studied no unequivocal prescription policy could be derived. Respondents who prescribed orthopaedic footwear more than the median (more than 50 prescriptions per year) were more often rehabilitation practitioner, perceived more advantages of prescription footwear, perceived less disadvantages of prescription footwear and were more satisfied about the co-operation with the pedorthist.

CONCLUSION

In some medical conditions orthopaedists and rehabilitation practitioners agree about the optimal use of orthopaedic footwear. In some other medical conditions orthopaedists and rehabilitation practitioners are divided about the use of orthopaedic footwear. Reported rate of prescription was not related to desirability of prescription, but was related to beliefs such as perceived advantages, perceived disadvantages and satisfaction with co-operation with the pedorthist, underlining the importance of cognitive factors in prescription style.

[Knowledge about drugs used by adult patients with asthma for self-treatment]

OBJECTIVE

To assess the knowledge of adult asthmatics about medication for self-treatment.

DESIGN

Descriptive.

SETTING

Department of Pulmonary Diseases, Medisch Spectrum Twente, Enschede, the Netherlands.

METHODS

As a part of a larger project aimed at improvement of self-management and self-treatment, all adults aged 18-65 years in Enschede (population 146,000) reported by the city pharmacists as using medication for asthma or chronic obstructive pulmonary disease, in 1994 were sent a questionnaire including 7 items pertaining to knowledge about lung medication. From among those who failed to respond after a written reminder and an appeal in local papers, a random group of 9% were interviewed by telephone. Of the responders who reported that according to their GPs they had asthma and who had answered the questions on medication, the number of questions answered correctly was counted; in addition, the question was investigated whether their level of knowledge was related to sex, education, use of (inhalation) corticosteroids and the form of explanation received.

RESULTS

A total of 4563 questionnaires were sent out: 2259 (50%) usable forms were returned. The responders were better educated than the 192 non-responders interviewed, but did not differ as to age or sex. Of the responders, 1262 (56%) reported that their GPs had told them they had asthma. On average they had answered 2.4 (range: 0-7) out of 7 questions correctly. Previous instruction, number of sources of information, duration of taking medication, use of inhaled steroids, female sex and better education were all positively related with a higher knowledge score in this group.

CONCLUSION

Adult asthmatics did not have sufficient knowledge about their medication. Improving such knowledge should therefore be an important element in the development of a self-management programme.

Evaluation of the long-term effectiveness of three instruction modes for inhaling medicines

Inhaled medication is important in the treatment of chronic obstructive pulmonary disease (COPD). In this paper a comparison of the long-term efficacy of three instruction-models is presented. A total of 152 COPD-patients were randomized into one of four groups: Personal-, video-, group-instruction and a control group. Inhalation technique was assessed by means of checklists, on which essential inhalation manoeuvres were identified. Up to 9 months later, 148 patients returned for follow-up assessment. Prior to instruction 61% of patients in the control group had a perfect score on essential actions, compared to 62, 65 and 53% for those receiving group-, personal- and video-instruction respectively. At follow-up these percentages were 49, 97, 75 and 76%. For group-(35%) and video-instruction (24%) the increase from baseline was significant. Examining the different inhalers under investigation, it is striking, that only 24% of all patients with a Metered Dose Inhaler (MDI) performed all essential checklist items correctly, versus 96% for those using a Diskhaler. The fact that for the MDI this percentage improved to 90% post-instruction, shows that time spent on instruction, is time well spent. We conclude that group instruction seems superior to personal counselling, and equally effective or even better than video instruction. Personal instruction should not be dismissed and a combination with video instruction might prove to be effective as well.

Are high generalised and asthma-specific self-efficacy predictive of adequate self-management behaviour among adult asthma patients?

In asthma self-management training, often self-treatment guidelines are included, because increased knowledge of asthma alone is not sufficient to change behaviour. One way to achieve behavioural changes is by increasing the patient's general and asthma-specific self-efficacy expectancies. This refers to beliefs in one's capabilities to execute the recommended course of action successfully. We wanted to assess whether high generalised and asthma-specific self-efficacy expectancies were predictive of adequate self-management and self-treatment behaviour. A questionnaire was sent to 4563 persons (18-65 years) who had used inhaled medication in 1993. Self-management and self-treatment behaviour were operationalised through a hypothetical scenario of a slow-onset asthma exacerbation. Of all 1262 asthmatic patients, 39.3% showed adequate self-treatment behaviour (self-adjusting their inhaled or oral steroids when appropriate). Age, asthma-specific outcome expectancies and knowledge were predictive of adequate self-treatment. Adequate self-management behaviour (self-treatment or seeking medical help) was observed in 56.4% of patients. Intentions towards self-management and asthma-specific knowledge were significant. Only knowledge has a relevant influence on both. Asthma-specific knowledge is the only factor that seems relevant for adequate self-management and self-treatment behaviour, which might be explained by the hypothetical nature of the scenario. When patients experience a real asthma exacerbation, self-efficacy expectancies will become more important. Only if knowledge of what to do is present will patients be able to show proper self-management and self-treatment behaviour. Our results suggest that self-treatment guidelines are only effective in combination with patient education, which is important for optimal control of their disease.

Health education to improve repeat participation in the Dutch breast cancer screening programme: evaluation of a leaflet tailored to previous participants

Participation in breast cancer screening programmes often declines in the course of the programme. The purpose of the present study was to examine whether health education could diminish the amount of drop-outs between two screening rounds. The health education was tailored to women who previously underwent mammography. Based on the Elaboration Likelihood Model two versions of the tailored leaflet were made: a simple version and a version with additional peripheral cues. In an experimental study among 2961 women the effects of the tailored leaflets on reparticipation were tested against a standard leaflet. Re-participation rates were high (> 90%) and did not differ between the 3 groups. No significant differences regarding beliefs about re-participating were found between the 3 groups. Results indicate that the tailored information leaflets did not enhance re-participation. Therefore, the required additional efforts and costs do not seem to be justified. The results of the study provide indications that less painful mammograms and friendly staff might improve re-participation.

Group education for patients with rheumatoid arthritis

Patients with rheumatoid arthritis must learn to adjust their exercise, rest and medication to the varying activity of the disease. Patient education can help patients in making the right decisions about adjustments in their treatment regimen and in attaining "self-management" behaviors. We developed a group education program based on social learning theory and the 'Arthritis Self-Management Course' developed in the USA by Lorig. Goal of the program is the strengthening of self-efficacy, outcome expectations and self-management behaviors of RA patients which may lead to better health status. The program has been evaluated in an experimental design. We established significant positive effects of the group training on functional disability, joint tenderness, practice of relaxation and physical exercises, self-management behavior, outcome expectations, self-efficacy function and knowledge. After 14 months we still found effects on practice of physical exercises, self-efficacy function and knowledge.

Health status, adherence with health recommendations, self-efficacy and social support in patients with rheumatoid arthritis

A study was performed in 86 patients with rheumatoid arthritis (RA) to assess their health problems, the problems they experience in adhering to health recommendations and the relationships of these problems with self-efficacy and social support. Feeling dependent, disability and pain were the most important health related problems. The results showed self-efficacy to be related to the subjective experience of health status as measured by DUTCH-AIMS. Social emotional support was not related to health status, and contrary to what we expected social instrumental support was positively related to health status. The majority of the patients (55%) experienced adherence problems with health recommendations. These problems were not related to functional incapacity, pain or other aspects of health status but to the patient's self-efficacy expectations about coping with arthritis. Our conclusion is that to improve the self-management of disability and pain and adherence to health recommendations, patient education should be aimed at strengthening self-efficacy expectations in which social emotional support might be a motivating factor.

Evaluation of the Dutch Arthritis Impact Measurement Scales (DUTCH-AIMS) in patients with rheumatoid arthritis

The Arthritis Impact Measurement Scales (AIMS) have been used to measure health status in patients with rheumatic diseases in North America. In this study, a Dutch version of this self-assessment questionnaire named the DUTCH-AIMS was evaluated in 73 Dutch patients with rheumatoid arthritis. Significant correlations between scores from the DUTCH-AIMS on the one hand and ARA functional class, haemoglobin, erythrocyte sedimentation rate, self-assessments of functional impairment and perceived overall health on the other hand indicate that the scales are valid and provide good estimations of various components of the health status of the Dutch arthritic patient.

Previous experiences with epilepsy and effectiveness of information to change public perception of epilepsy

Differences with regard to the effectiveness of health information and attitude change are suggested between people with direct, behavioral experiences with a health topic and people with indirect, nonbehavioral experiences. The effects of three different methods of health education about epilepsy, frequently used in health education practice, are assessed in a pretest posttest design with control groups, controlling for experiences with epilepsy. Subjects were 132 students from teacher-training colleges. After all treatments, attitudes, and knowledge about epilepsy were changed in a positive way. Treatments were found to be equally effective. Before treatment, direct behavioral experiences were related to knowledge and a more positive attitude towards epilepsy. After treatment, subjects with direct behavioral experiences with epilepsy showed less change of attitude and knowledge as compared with subjects with indirect experiences. Direct experiences appear to restrain the processing of new information and attitude change.
