Impact of primary healthcare providers' initial role security and therapeutic commitment on implementing brief interventions in managing risky alcohol consumption: a cluster randomised factorial trial.

BACKGROUND: Brief interventions in primary healthcare are cost-effective in reducing drinking problems but poorly implemented in routine practice. Although evidence about implementing brief interventions is growing, knowledge is limited with regard to impact of initial role security and therapeutic commitment on brief intervention implementation. METHODS: In a cluster randomised factorial trial, 120 primary healthcare units (PHCUs) were randomised to eight groups: care as usual, training and support, financial reimbursement, and the opportunity to refer patients to an internet-based brief intervention (e-BI); paired combinations of these three strategies, and all three strategies combined. To explore the impact of initial role security and therapeutic commitment on implementing brief interventions, we performed multilevel linear regression analyses adapted to the factorial design. RESULTS: Data from 746 providers from 120 PHCUs were included in the analyses. Baseline role security and therapeutic commitment were found not to influence implementation of brief interventions. Furthermore, there were no significant interactions between these characteristics and allocated implementation groups. CONCLUSIONS: The extent to which providers changed their brief intervention delivery following experience of different implementation strategies was not determined by their initial attitudes towards alcohol problems. In future research, more attention is needed to unravel the causal relation between practitioners' attitudes, their actual behaviour and care improvement strategies to enhance implementation science.

Improving the delivery of brief interventions for heavy drinking in primary health care: outcome results of the Optimizing Delivery of Health Care Intervention (ODHIN) five-country cluster randomized factorial trial.

AIM: To test if training and support, financial reimbursement and option of referring screen-positive patients to an internet-based method of giving advice (eBI) can increase primary health-care providers' delivery of Alcohol Use Disorders Identification Test (AUDIT)-C-based screening and advice to heavy drinkers. DESIGN: Cluster randomized factorial trial with 12-week implementation and measurement period. SETTING: Primary health-care units (PHCU) in different locations throughout Catalonia, England, the Netherlands, Poland and Sweden. PARTICIPANTS: A total of 120 PHCU, 24 in each of Catalonia, England, the Netherlands, Poland and Sweden. INTERVENTIONS: PHCUs were randomized to one of eight groups: care as usual, training and support (TS), financial reimbursement (FR) and eBI; paired combinations of TS, FR and eBI, and all of FR, TS and eBI. MEASUREMENTS: The primary outcome measure was the proportion of eligible adult (age 18+ years) patients screened during a 12-week implementation period. Secondary outcome measures were proportion of screen-positive patients advised; and proportion of consulting adult patients given an intervention (screening and advice to screen-positives) during the same 12-week implementation period. FINDINGS: During a 4-week baseline measurement period, the proportion of consulting adult patients who were screened for their alcohol consumption was 0.059 per PHCU (95% CI 0.034 to 0.084). Based on the factorial design, the ratio of the logged proportion screened during the 12-week implementation period was 1.48 (95% CI = 1.13-1.95) in PHCU that received TS versus PHCU that did not receive TS; for FR, the ratio was 2.00 (95% CI = 1.56-2.56). The option of referral to eBI did not lead to a higher proportion of patients screened. The ratio for TS plus FR was 2.34 (95% CI = 1.77-3.10), and the ratio for TS plus FR plus eBI was1.68 (95% CI = 1.11-2.53). CONCLUSIONS: Providing primary health-care units with training, support and financial reimbursement for delivering Alcohol Use Disorders Identification Test-C-based screening and advice to heavy drinkers increases screening for alcohol consumption. Providing primary health-care units with the option of referring screen-positive patients to an internet-based method of giving advice does not appear to increase screening for alcohol consumption.

Professional's Attitudes Do Not Influence Screening and Brief Interventions Rates for Hazardous and Harmful Drinkers: Results from ODHIN Study.

AIMS: To determine the relation between existing levels of alcohol screening and brief intervention rates in five European jurisdictions and role security and therapeutic commitment by the participating primary healthcare professionals. METHODS: Health care professionals consisting of, 409 GPs, 282 nurses and 55 other staff including psychologists, social workers and nurse aids from 120 primary health care centres participated in a cross-sectional 4-week survey. The participants registered all screening and brief intervention activities as part of their normal routine. The participants also completed the Shortened Alcohol and Alcohol Problems Perception Questionnaire (SAAPPQ), which measure role security and therapeutic commitment. RESULTS: The only significant but small relationship was found between role security and screening rate in a multilevel logistic regression analysis adjusted for occupation of the provider, number of eligible patients and the random effects of jurisdictions and primary health care units (PHCU). No significant relationship was found between role security and brief intervention rate nor between therapeutic commitment and screening rate/brief intervention rate. The proportion of patients screened varied across jurisdictions between 2 and 10%. CONCLUSION: The findings show that the studied factors (role security and therapeutic commitment) are not of great importance for alcohol screening and BI rates. Given the fact that screening and brief intervention implementation rate has not changed much in the last decade in spite of increased policy emphasis, training initiatives and more research being published, this raises a question about what else is needed to enhance implementation.

The effects of a web-based decision aid on the intention to diagnostic self-testing for cholesterol and diabetes: a randomized controlled trial.

BACKGROUND: Diagnostic self-tests are becoming increasingly available. Since the pros and cons of self-testing are unclear and neutral information on self-testing is lacking, two decision aids (DAs) on self-testing for cholesterol and diabetes were developed to support consumers in making an informed choice that is in line with their personal values. We aimed to evaluate the effect of the DAs on the intention to self-test for cholesterol or diabetes, as well as socio-cognitive determinants of that intention. METHODS: 1137 people of an internet panel with an intention to use a diagnostic self-test for cholesterol or diabetes were enrolled in a web-based randomized controlled trial consisting of four groups: a cholesterol intervention and control group and a diabetes intervention and control group. The study was conducted in September and October 2011. The intervention groups received an interactive online DA with general information on self-testing and test-specific information on cholesterol or diabetes self-testing, whereas the control groups received a limited information sheet with general information on self-testing. The intention to use a self-test for cholesterol or diabetes and perceived susceptibility, perceived severity, cues to action, perceived benefits, perceived barriers, self-efficacy and ambivalence towards self-testing were assessed directly after being exposed to the intervention or control information. RESULTS: Follow-up measurement was completed by 922 people. Analyses showed a significant group by intention at baseline interaction effect within the diabetes condition. Further exploration of this interaction showed that a main group-effect was only observed among maybe-intenders; intention of participants in the intervention group did not change between baseline and follow-up, while intention slightly increased in the control group. We observed a significant main effect of group on cues to action in the cholesterol condition. CONCLUSIONS: We found limited effects of the DAs on intention and its determinants. Although the time spent on the DAs was limited, we might assume that our DAs contain neutral information on self-testing for cholesterol and diabetes. By implementing our DAs in real life among people who probably or definitely intend to use a self-test and by assessing weblog files, we might be able to determine the effectiveness of our DAs on self-test behaviour.

Managing alcohol problems in general practice in Europe: results from the European ODHIN survey of general practitioners.

AIMS: To document the attitudes of general practitioners (GPs) from eight European countries to alcohol and alcohol problems and how these attitudes are associated with self-reported activity in managing patients with alcohol and alcohol problems. METHODS: A total of 2345 GPs were surveyed. The questionnaire included questions on the GP's demographics, reported education and training on alcohol, attitudes towards managing alcohol problems and self-reported estimates of numbers of patients managed for alcohol and alcohol problems during the previous year. RESULTS: The estimated mean number of patients managed for alcohol and alcohol problems during the previous year ranged from 5 to 21 across the eight countries. GPs who reported higher levels of education for alcohol problems and GPs who felt more secure in managing patients with such problems reported managing a higher number of patients. GPs who reported that doctors tended to have a disease model of alcohol problems and those who felt that drinking was a personal rather than a medical responsibility reported managing a lower number of patients. CONCLUSION: The extent of alcohol education and GPs' attitudes towards alcohol were associated with the reported number of patients managed. Thus, it is worth exploring the extent to which improved education, using pharmacotherapy in primary health care and a shift to personalized health care in which individual patients are facilitated to undertake their own assessment and management (individual responsibility) might increase the number of heavy drinkers who receive feedback on their drinking and support to reduce their drinking.

Quality and use of consumer information provided with home test kits: room for improvement.

BACKGROUND: Diagnostic self-tests (tests on body materials that are initiated by consumers with the aim of diagnosing a disorder or risk factor) are becoming increasingly available. Although the pros and cons of self-testing are currently not clear, it is an existing phenomenon that is likely to gain further popularity. OBJECTIVE: To examine consumers' use of and needs for information about self-testing, and to assess the quality of consumer information provided with home test kits, as perceived by consumers and as assessed using a checklist of quality criteria. METHODS: A cross-sectional Internet survey among 305 self-testers assessed their use of and needs for information and their perception of the quality of consumer information provided with self-test kits. A meta-search engine was used to identify Dutch and English consumer information for home diagnostic tests available online at the time of the study. The quality of this consumer information was evaluated using a checklist of quality criteria. RESULTS: The consumers' information needs were in line with the most frequently used information, and the information was perceived as being of moderate to good quality. The information was mostly in agreement with clinical practice guidelines, although information on reliability and follow-up behaviour was limited. Approximately half of the instruction leaflets did not include information on the target group of the test. CONCLUSIONS: Although generally of moderate to good quality, some aspects of the information provided were in many cases insufficient. European legislation concerning self-tests and accompanying information needs to be adapted and adhered to more closely.

Motivation and experiences of self-testers regarding tests for cardiovascular risk factors.

BACKGROUND: In recent years, self-tests have become increasingly available to the general public, though their value is still being debated. Because these tests are available, consumers should have access to clear information about self-testing. Examining experiences of self-testers could contribute to the development of consumer information. OBJECTIVE: Detailed exploration of consumers' experiences with self-testing for cardiovascular risk factors. METHODS: Semi-structured interviews with 20 consumers who had performed a self-test for glucose, cholesterol or albuminuria. The main topics of the interviews were reasons for self-testing, performing the self-test, follow-up behaviour and perceived need for information on self-testing. Data were analysed using thematic content analysis. RESULTS: Regarding the reason for self-testing, three types of users were distinguished: those who engaged in self-testing when a test was offered, either with or without previous knowledge about the disease or risk factor, and those who had actively decided to test and had searched for a self-test themselves. Self-testers had generally experienced no problems performing the test or interpreting the result and had considerable confidence in the result. They were easily reassured by a normal result, while an abnormal result did not automatically mean they consulted a doctor. Most participants did not feel the need for more information. CONCLUSIONS: Self-testers often perform tests for reassurance, without considering the disadvantages, such as the absence of professional counselling and the risk of false-positive or false-negative results. Consumer information should promote more informed and deliberate choices for self-testing.

Psychosocial determinants of the intention to use a chlamydia home self-test: awareness of risk behaviour and test accuracy are important elements of educational interventions.

BACKGROUND: The aim of the present study was to investigate the association between psychosocial variables and the intention to use a chlamydia (Chlamydia trachomatis) home self-test, to enable information to be tailored to the target population. METHODS: A cross-sectional survey was carried out among an internet panel. A questionnaire was sent to a sample of 227 panelists in October 2006. A multiple linear regression analysis was conducted to assess the predictive value of the psychosocial factors for the intention to test. RESULTS: The response rate was 88% (n=200). Respondents with higher intentions to use a home self-test were younger, perceived themselves to be more susceptible to chlamydia, had more personal experience with chlamydia, felt a stronger moral obligation to do a test and had a higher level of response efficacy than those with lower intentions. CONCLUSIONS: This study provides topics for educational interventions aimed at encouraging chlamydia testing in general, and at developing a more effective use of home self-test. Awareness of personal behaviour and information about the probability of false positive and false negative test results with home self-tests should be elements of these interventions.

A single-blind randomised controlled trial of the effects of a web-based decision aid on self-testing for cholesterol and diabetes. Study protocol.

BACKGROUND: Self-tests, tests on body materials to detect medical conditions, are widely available to the general public. Self-testing does have advantages as well as disadvantages, and the debate on whether self-testing should be encouraged or rather discouraged is still ongoing. One of the concerns is whether consumers have sufficient knowledge to perform the test and interpret the results. An online decision aid (DA) with information on self-testing in general, and test specific information on cholesterol and diabetes self-testing was developed. The DA aims to provide objective information on these self-tests as well as a decision support tool to weigh the pros and cons of self-testing. The aim of this study is to evaluate the effect of the online decision aid on knowledge on self-testing, informed choice, ambivalence and psychosocial determinants. METHODS/DESIGN: A single blind randomised controlled trial in which the online decision aid 'zelftestwijzer' is compared to short, non-interactive information on self-testing in general. The entire trial will be conducted online. Participants will be selected from an existing Internet panel. Consumers who are considering doing a cholesterol or diabetes self-test in the future will be included. Outcome measures will be assessed directly after participants have viewed either the DA or the control condition. Weblog files will be used to record participants' use of the decision aid. DISCUSSION: Self-testing does have important pros and cons, and it is important that consumers base their decision whether they want to do a self-test or not on knowledge and personal values. This study is the first to evaluate the effect of an online decision aid for self-testing. TRIAL REGISTRATION: Dutch Trial Register: NTR3149.

To test or not to test: a cross-sectional survey of the psychosocial determinants of self-testing for cholesterol, glucose, and HIV.

BACKGROUND: Although self-tests are increasingly available and widely used, it is not clear whether their use is beneficial to the users, and little is known concerning the determinants of self-test use. The aim of this study was to identify the determinants of self-test use for cholesterol, glucose, and HIV, and to examine whether these are similar across these tests. Self-testing was defined as using in-vitro tests on body materials, initiated by consumers with the aim of diagnosing a particular disorder, condition, or risk factor for disease. METHODS: A cross-sectional Internet survey was conducted among 513 self-testers and 600 non-testers, assessing possible determinants of self-test use. The structured questionnaire was based on the Health Belief Model, Theory of Planned Behavior, and Protection Motivation Theory. Data were analyzed by means of logistic regression. RESULTS: The results revealed that perceived benefits and self-efficacy were significantly associated with self-testing for all three conditions. Other psychosocial determinants, e.g. gender, cues to action, perceived barriers, subjective norm, and moral obligation, seemed to be more test-specific. CONCLUSIONS: Psychosocial determinants of self-testing are not identical for all tests and therefore information about self-testing needs to be tailored to a specific test. The general public should not only be informed about advantages of self-test use but also about the disadvantages. Designers of information about self-testing should address all aspects related to self-testing to stimulate informed decision making which, in turn, will result in more effective self-test use.

How do people respond to self-test results? A cross-sectional survey.

BACKGROUND: Self-tests, tests on medical conditions that can be performed by consumers without consulting a doctor first, are frequently used. Nevertheless, there are concerns about the safety of self-testing, as it may delay diagnosis and appropriate treatment in the case of inappropriate use of the test, or false-negative results. It is unclear whether self-tests stimulate appropriate follow-up behaviour. Our aim was to examine the frequency of self-test use, consumers' response to self-test results in terms of their confidence in the result, reassurance by the test result, and follow-up behaviour. METHODS: A two step cross-sectional survey was designed. A random sample of 6700 Internet users in an existing Internet panel received an online questionnaire on the use of self-tests. Self-tests were defined as tests on body materials, initiated by consumers with the aim to diagnose a disease or risk factor. A second questionnaire on consumers' response to self-test results was sent to the respondents that were identified as a self-tester in the first questionnaire (n = 703). RESULTS: 18.1% (799/4416) of the respondents had ever performed a self-test, the most frequently used tests being those for diabetes (5.3%), kidney disease (4.9%), cholesterol (4.5%), urinary tract infection (1.9%) and HIV/AIDS and Chlamydia (both 1.6%). A total of 78.1% of the testers with a normal test result and 81.4% of those with an abnormal result reported confidence in this result. Almost all (95.6%) of the testers with a normal result felt reassured. After a normal result, 78.1% did not take any further action and 5.8% consulted a doctor. The corresponding figures after an abnormal test result were 9.3% and 72.2%, respectively. CONCLUSIONS: Respondents who had performed a self-test seemed to base their follow-up behaviour on the result of the test. They had confidence in the test result, and were often reassured by a normal result. After an abnormal result, most self-testers sought medical care. Because consumers seem to trust the self-test results, further research should focus on the development of consumer information addressing indications for performing a self-test, the validity of self-tests and appropriate interpretation of and management after a test.

Improving behaviour in self-testing (IBIS): Study on frequency of use, consequences, information needs and use, and quality of currently available consumer information (protocol).

BACKGROUND: Self-tests are available to consumers for more than 25 conditions, ranging from infectious diseases to cardiovascular risk factors. Self-tests are defined as in-vitro tests on body materials such as blood, urine, faeces, or saliva that are initiated by consumers to diagnose a particular disorder or risk factor without involving a medical professional. In 2006, 16% of a sample of Dutch Internet users had ever used at least one self-test and 17% intended to use a self-test in the future. The objectives of this study are to determine (1) the frequency of self-test use, (2) the consumers' reasons for using or not using a self-test, (3) the information that is used by self-testers in the different self-test stages and the consumers' interpretation of the quality of this information, (4) the consumers' response to self-test results in terms of their confidence in the result, reassurance by the test result, and follow-up behaviour, (5) the information consumers report to need in the decision making process of using or not using a self-test, and in further management on the basis of the self-test result, and (6) the quality of the currently available consumer information on a selected set of self-tests. METHODS: Mixed methods study with (1) a cross-sectional study consisting of a two-phase Internet-questionnaire, (2) semi-structured interviews with self-testers and consumers who intend to use a self-test, and (3) the assessment of the quality of consumer information of self-tests. The Health Belief Model and the Theory of Planned Behaviour will serve as the theoretical basis for the questionnaires and the interview topic guides. CONCLUSIONS: The self-testing area is still in a state of flux and therefore it is expected that self-test use will increase in the future. To the best of our knowledge, this is the first study which combines quantitative and qualitative research to identify consumers' information needs and use concerning self-testing, and the consumers' actual follow-up behaviour based on the self-test result, and simultaneously investigates the quality of the currently available consumer information. The results of this study will be used as an input in developing consumer information on self-testing.

Improving lifestyle and risk perception through patient involvement in nurse-led cardiovascular risk management: a cluster-randomized controlled trial in primary care.

OBJECTIVE: To determine if lifestyle improved at a short term through an intervention to involve patients in cardiovascular risk management by the practice nurse. METHODS: The IMPALA study (2006, the Netherlands) was a cluster-randomised controlled trial involving 25 general practices and 615 patients who were eligible for cardiovascular risk management. The intervention consisted of (1) individual 10-year cardiovascular risk assessment, (2) risk communication, (3) use of a decision aid and (4) adapted motivational interviewing, applied by practice nurses in two consultations. Outcomes were smoking, alcohol, diet, physical activity and the secondary outcomes risk perception, anxiety, confidence about the decision and satisfaction with the communication, measured at baseline and after 12 weeks. RESULTS: Patients of both groups improved their lifestyle, but no relevant significant differences between the groups were found. Intervention group patients improved in terms of the appropriateness of risk perception, although not significantly. Intervention group patients improved significantly in terms of appropriateness of anxiety and were more satisfied with the communication compared to control group patients. CONCLUSION: The intervention seems to have improved the patients' risk perception, anxiety and satisfaction with the communication, which are important conditions for shared decision making. However, we found no additional effect of the intervention on lifestyle.

Involving patients in cardiovascular risk management with nurse-led clinics: a cluster randomized controlled trial.

BACKGROUND: Preventive guidelines on cardiovascular risk management recommend lifestyle changes. Support for lifestyle changes may be a useful task for practice nurses, but the effect of such interventions in primary prevention is not clear. We examined the effect of involving patients in nurse-led cardiovascular risk management on lifestyle adherence and cardiovascular risk. METHODS: We performed a cluster randomized controlled trial in 25 practices that included 615 patients. The intervention consisted of nurse-led cardiovascular risk management, including risk assessment, risk communication, a decision aid and adapted motivational interviewing. The control group received a minimal nurse-led intervention. The self-reported outcome measures at one year were smoking, alcohol use, diet and physical activity. Nurses assessed 10-year cardiovascular mortality risk after one year. RESULTS: There were no significant differences between the intervention groups. The effect of the intervention on the consumption of vegetables and physical activity was small, and some differences were only significant for subgroups. The effects of the intervention on the intake of fat, fruit and alcohol and smoking were not significant. We found no effect between the groups for cardiovascular 10-year risk. INTERPRETATION: Nurse-led risk communication, use of a decision aid and adapted motivational interviewing did not lead to relevant differences between the groups in terms of lifestyle changes or cardiovascular risk, despite significant within-group differences.

Use of diagnostic self-tests on body materials among Internet users in the Netherlands: prevalence and correlates of use.

BACKGROUND: A range of self-tests on body materials has become available to the general public, but the extent of their use has hardly been studied. This study examined how many people use diagnostic self-tests on body materials such as blood or urine, as well as the type of tests that are used, and factors associated with their use. METHODS: Cross-sectional survey. Participants were recruited from an existing Dutch Internet panel of 12,529 persons, and information was collected by means of a structured Internet-based questionnaire. Multiple logistic regression analyses were used to assess correlates of self-test use. RESULTS: Response to the survey was 63%. Sixteen percent of the respondents said they had ever used at least one self-test, with a mean of 2.1 tests per self-tester. The most frequently reported self-tests were those for diabetes and cholesterol. Self-testers generally reported lower health status and had a higher BMI than non-testers. On the other hand, they were more likely to engage in health-related behaviour such as the use of dietary supplements and homeopathic medicine. CONCLUSION: Self-testing proved to be relatively prevalent among Dutch Internet users. We therefore think that it is essential to develop appropriate information for consumers, health care providers and policymakers, about the pros and cons of self-testing and specific self-tests. More test-specific research is needed.

Improving patient adherence to lifestyle advice (IMPALA): a cluster-randomised controlled trial on the implementation of a nurse-led intervention for cardiovascular risk management in primary care (protocol).

BACKGROUND: Many patients at high risk of cardiovascular diseases are managed and monitored in general practice. Recommendations for cardiovascular risk management, including lifestyle change, are clearly described in the Dutch national guideline. Although lifestyle interventions, such as advice on diet, physical exercise, smoking and alcohol, have moderate, but potentially relevant effects in these patients, adherence to lifestyle advice in general practice is not optimal. The IMPALA study intends to improve adherence to lifestyle advice by involving patients in decision making on cardiovascular prevention by nurse-led clinics. The aim of this paper is to describe the design and methods of a study to evaluate an intervention aimed at involving patients in cardiovascular risk management. METHODS: A cluster-randomised controlled trial in 20 general practices, 10 practices in the intervention arm and 10 in the control arm, starting on October 2005. A total of 720 patients without existing cardiovascular diseases but eligible for cardiovascular risk assessment will be recruited. In both arms, the general practitioners and nurses will be trained to apply the national guideline for cardiovascular risk management. Nurses in the intervention arm will receive an extended training in risk assessment, risk communication, the use of a decision aid and adapted motivational interviewing. This communication technique will be used to support the shared decision-making process about risk reduction. The intervention comprises 2 consultations and 1 follow-up telephone call. The nurses in the control arm will give usual care after the risk estimation, according to the national guideline. Primary outcome measures are self-reported adherence to lifestyle advice and drug treatment. Secondary outcome measures are the patients' perception of risk and their motivation to change their behaviour. The measurements will take place at baseline and after 12 and 52 weeks. Clinical endpoints will not be measured, but the absolute 10-year risk of cardiovascular events will be estimated for each patient from medical records at baseline and after 1 year. DISCUSSION: The combined use of risk communication, a decision aid and motivational interviewing to enhance patient involvement in decision making is an innovative aspect of the intervention. TRIAL REGISTRATION: Current Controlled Trials ISRCTN51556722.

The reach of a computer-tailored nutrition education program in the Dutch heart health community intervention "Hartslag Limburg".

OBJECTIVE: To study the reach of an efficacious, computer-tailored nutrition education tool in a field setting. DESIGN: Data from self-administered questionnaires were used. SETTING: The computer-tailored nutrition education tool (CTT) was adopted by a regional public health service organization and implemented in a regional heart-health community project. PARTICIPANTS: The 1293 inhabitants of the region that requested the computer nutrition education tool during a 25-month implementation period. MAIN OUTCOME MEASURES: Demographic characteristics; intake of fat, fruit, and vegetables; and psychosocial behavioral determinants. ANALYSIS: Descriptive statistics. RESULTS: The CTT reached almost 1% of the targeted population. Most participants were female (82%), and almost half were low educated. Many participants had diets higher in fat and lower in fruits and vegetables than recommended, were unaware of their unfavorable diets, and had low self-efficacy and intentions towards change. CONCLUSIONS AND IMPLICATIONS: Only a small, but possibly important, part of the target population was reached. Additional ways to reach more people should be explored.

Evaluation of a Dutch public-private partnership to promote healthier diet.

PURPOSE: Public-private partnerships may help to promote healthy diets. We assessed customers' exposure to and the acceptability of a Dutch public-private healthy diet campaign in butcher's shops and investigated the effects on the purchase of lean meat and the use of liquid cooking margarine and potential behavioral determinants. METHODS: The pretest-posttest control group design included 486 customers (242 experimental and 244 control) of butcher shops representing 64% of the original sample. Campaign exposure, acceptability, and behavioral effects were measured by a questionnaire. RESULTS: Seventy-one percent of the customers noticed the campaign. Scores on the acceptability were positive to very positive. Regression analysis revealed that customers in the experimental condition evaluated the campaign better (B = .415; p < .05) and felt more encouraged to buy lean meat (B = .252; p < .05) than customers in the control condition. No effects on behavior were found. DISCUSSION: Study design limitations included possible campaign exposure of control group participants. The study shows the feasibility and acceptability of a joint health-promoting activity through a public-private partnership, but there were no effects on behavior.

The Dutch Heart Health Community Intervention 'Hartslag Limburg': effects on smoking behaviour.

BACKGROUND AND METHODS: A pretest-posttest control group design with two posttests was used to evaluate the effects of a regional Dutch Heart Health Community Intervention on smoking behaviour and its determinants. At baseline, a cohort research population of 1,200 smokers was recruited in the intervention region and in a control region. Data was gathered by means of short structured telephone interviews. RESULTS: No significant differences were found between the intervention region and the control region on smoking behaviour and its determinants. CONCLUSION: It is concluded that the regional intervention was unable to exceed secular trends in smoking cessation.
