1. General questions GGD Health Monitor 2024

1.1 What is the GGD Health Monitor 2024?

The GGD Health Monitor 2024 is a national questionnaire about health, well-being and lifestyle of residents of the Netherlands aged 18 and over. The study will start in September 2024. About 1.5 million people throughout the Netherlands are invited to complete the questionnaire. In your GGD region, almost 30.000 residents have received an invitation.

1.2 What is the purpose of the monitor?

Municipalities in the Netherlands have a legal obligation to monitor the health of their residents. This statutory task is carried out for the municipalities by the Municipal Public Health Service (GGD). The GGD does this at least once every four years. The GGD Health Monitor Adults and Eldery 2024 will be used by the GGDs to provide insight into the physical and mental health of adults and elderly at national, regional and municipal levels. The GGDs will also compare the results with the results of previous monitors. The monitor results form an important basis for the development and implementation of local health policy for municipalities. For example, the results may show that more help is needed for certain groups, or that extra facilities are required in a municipality or neighbourhood. Through cooperation with the National Institute for Public Health and Environment (RIVM) and Statistics Netherlands (CBS), the monitor will also provide information about health of people in the Netherlands as a whole.

1.3 Which organisations are involved in the monitor?

The GGD, the public health department of the municipality of Utrecht, the National Institute for Public Health and the Environment (RIVM) and Statistics Netherlands (CBS) are carrying out this monitor together. Ipsos I&O collects the data on behalf of these parties. CBS receives data from other organisations – such as data on income and population composition - in addition to the data gathered for this monitor. CBS combines these data. This is useful for the GGD because it means fewer questions need to be added to the GGD Health monitor. Please note that no personal details can be identified in the merged datasets sent to the GGDs by CBS.

1.4 What is the role of Ipsos I&O?

Ipsos I&O has been asked to carry out the field work for the GGD Health Monitor 2024. This means that Ipsos I&O sends the invitations asking people to complete the questionnaire and collects the answers. To be able to send the invitations, CBS will provide Ipsos I&O with names and addresses. This data will be erased three months after completion of the monitor, in compliance with the requirements of the General Data Protection Regulations (GDPR).

1.5 When and where will the monitor be carried out?

The monitor will be conducted in the whole of the Netherlands and the questionnaire can be filled in between 23 September until at least 8 December 2024.

1.6 How will the monitor participants be selected?

The target population for the monitor concerns residents of the Netherlands aged 18 and over. CBS selected people from the Personal Records Database (BRP) for participation in the GGD Health Monitor 2024 at random; this is a random sample. The selected persons together provide an average representation of the Dutch population. Temporary residents, registered in the BRP, can also be invited for the GGD Health Monitor Adults and Eldery 2024. The people in the random sample receive an invitation to fill in a questionnaire from the regional GGD. The questionnaire can be filled in either online or on paper. People who are not selected will not receive a questionnaire and cannot take part in the monitor.

1.7 Why is it important to participate?

The questionnaire gives us insight in how you are doing. Are you healthy, do you feel happy, and are you satisfied with your local neigbourhood? By participating in this study and providing answers you are giving insight to the municipality and GGD in regards to the overall health and well-being of the residents. To obtain an accurate picture of health, well-being and lifestyle of residents of the Netherlands aged 18 and over, it is important that as many persons as possible complete the questionnaire. If not enough persons complete the questionnaire, the results will not be a good representation of the whole of the target population, making the research results less accurate, or even inaccurate. If the GGD and municipality know how you and other residents are doing, the municipality can draw up targeted policies and take action to improve health and well-being of residents. For example, the results may show that more help is needed for certain groups, or extra facilities are required in a municipality or neighbourhood.

1.8 What is in it for me?

By answering questions about your health, you are more likely to think about your own health and well-being. As a result, you may have questions about your health. For this reason, sources of information providing reliable health information are included at the end of the online questionnaire. These websites provide answers to questions that you may have after filling in the questionnaire. Finally, by completing the questionnaire you have a chance to win one of the 50 VVV Gift Cards worth 50 euros.

1.9 Where can I find more information?

For more information or if you have questions about this health monitor, please contact the Ipsos I&O helpdesk. Call Ipsos I&O free of charge on 0800-0191 (7 days a week, 09.00 – 21.00), or send an email to NLhelpdeskGM@ipsos.com.

2. Participation in the monitor

2.1 Why have I received an invitation?

We have sent invitations to approximately 1.5 million residents of the Netherlands, aged 18 and over to take part in the GGD Health Monitor 2024. Every resident in the Netherlands is registered with their municipality. CBS has selected persons at random from this register to take part in this monitor. If you have received an invitation, you are one of those persons. The selected persons together represent the total group of residents aged 18 and over in the municipality. Your name and address details will be used to send the invitation and any reminders to complete the questionnaire and to inform prize winners. This data will be erased three months after completion of the monitor.

2.2 Do I need to give permission somewhere for you to process my data?

No. By completing the online questionnaire (or sending the paper version), you agree in participating in the GGD Health Monitor 2024. We will remind you of this when you start the questionnaire. Note that you don't have to answer a certain question if you do not want to, you may adjust your answers, and you may stop filling in the questionnaire at any time. Your answers will be processed confidentially, will be stored safely and will not be shared with any party that is not named in the privacy statement. If you complete the questionnaire online but decide to stop filling it in, all answers that you have already provided will be saved. Should you decide that you do not want your answers to be used in the monitor, we will erase your answers. For this, contact Ipsos I&O at NLhelpdeskGM@ipsos.com or call 0800-0191 (7 days a week, 09.00 – 21.00). Once you have provided your login details, Ipsos I&O can erase your answers.

2.3 Do I have to participate in the monitor?

No, participation in the monitor is entirely voluntary, although we would very much appreciate it if you do take part. Your participation is important, because the results of the monitor will be used by the municipality to better align its policies and activities with the needs and requirements of its residents.

2.4 How can I participate?

You can fill in the questionnaire online or on paper, although online is quicker as you automatically skip the questions that do not apply to you. Moreover, the online questionnaire is available in English, the paper questionnaire is not. The invitation letter contains your personal login code; fill this in at www.startvragenlijst.nl/ggd to start the questionnaire. Do you prefer to fill in the questionnaire on paper? Then wait to participate until you receive a paper questionnaire from us. Once you fill in the paper questionnaire, you can return it in the enclosed return envelope without a stamp.

2.5 How long does it take to fill in the questionnaire?

Some people are quicker than others, but it should take about 30 minutes.

2.6 I’m doing fine, so do I still need to fill in the questionnaire?

Yes, please! The aim of this monitor is to get a good idea of how everyone aged 18 and over in the municipality is doing, not just people who are not doing so well. If only these people fill in the questionnaire, it will look like there are a lot of problems in a municipality, even though this may not be the case for everyone.

2.7 Why have I received a reminder?

We send a reminder to make sure that as many persons as possible complete the questionnaire. We use the login code or the code on the back of the paper questionnaire to work out who has not yet filled in the questionnaire. These persons receive a reminder. You will therefore also receive a reminder if you have started to fill in the questionnaire but have not yet completed it. Note that all address data will be erased three months after completion of the monitor.

2.8 I have received a reminder, but I have already filled in the questionnaire. Why is that?

We probably received or processed your questionnaire after the reminders had been sent. You do not need to contact Ipsos I&O or the GGD about this. Just throw away the reminder. You also receive a reminder if you have started to fill in the questionnaire but not yet completed it. In this case, please carry on filling in the questionnaire and complete it. If you leave the questionnaire then log in again, you can continue where you left off.

2.9 I can’t log in, what should I do?

Perhaps the Caps Lock is turned on or you have used capital letters in the login code when you should use small letters. You should type the address www.startvragenlijst.nl/ggd directly into the search window of your internet browser and not into a search engine (such as Google). If you are unable to log in, please contact Ipsos I&O at NLhelpdeskGM@ipsos.com or call 0800 0191 (7 days a week, 09.00 – 21.00).

2.10 I have lost my login code. Can I get a new one?

We cannot send a new login code, but you can wait for the reminder letter, which you will receive about three weeks after the invitation. This reminder contains the login code.

2.11 My computer has stopped working. Now what?

Do not worry if you are unable to carry on filling in the questionnaire because of a problem with your computer or because the page has timed out. You can simply log in again after ten minutes and carry on. The system needs this time to recognise that you are no longer filling in the questionnaire. The filled in answers are saved automatically, so you don’t have to start the questionnaire again.

2.12 I stopped halfway. Now what?

You can stop filling in the questionnaire at any time. You can simply log in again and carry on. The filled in answers so far are saved automatically, so you don’t have to start the questionnaire again.

2.13 I have lost the return envelope. Now what?

You can send back the questionnaire in a normal envelope without a postage stamp to I&O Research Antwoordnummer 90275 3009 VB Rotterdam

2.14 Is it possible to withdraw from the study after I have completed the questionnaire?

By completing the questionnaire, you agree in participating in the GGD Health Monitor 2024. Note that you do not have to answer certain questions if you do not want to, you may adjust your answers, and you may stop filling in the questionnaire at any time. If you want to stop halfway through and you do not want your answers to be saved, you will have to go back through the questionnaire to delete your answers. At the start of the questionnaire you will find the explanation of how to do this. You can also contact Ipsos I&O to delete your data. This is possible until December 8, 2024. Contact Ipsos I&O at NLhelpdeskGM@ipsos.com or call 0800 0191 (7 days a week, 09.00 – 21.00). Once you have provided your login details, Ipsos I&O will erase your answers.

2.15 Can someone else complete the questionnaire for me?

No, it is important that the questionnaire is filled in by the person to whom the invitation is sent. Please, check if your name is addressed on the invitation letter. If not, please give the questionnaire to the person it is addressed to. People are selected to take part in the monitor at random, and the selected persons together provide an average representation of people in the whole of the municipality. Are you unable to complete the questionnaire on your own? If so, ask a family member or someone else to help, but you must fill in your answers. You can also contact Ipsos I&O at NLhelpdeskGM@ipsos.com or call 0800-0191 (7 days a week, 09.00 – 21.00) if you need help filling out the questionnaire.

2.16 Can I get help filling in the questionnaire?

Yes, a helpdesk employee can assist you with filling in the questionnaire. You can get assistance in various languages. Call the helpdesk (Ipsos I&O) free of charge on 0800-0191 (7 days a week, 09.00 – 21.00).

3. Privacy

3.1 What happens to the data that is collected?

The aim of the Health Monitor Adults and Eldery 2024 is to monitor the health of adults over a period of time. To enable comparisons to be made with this and previous monitors, we need to save the results. We have taken the required technical and organisational measures to ensure that the data is protected, and the data that we store will not contain any directly identifiable information. Names and addresses are used by Ipsos I&O to send the invitations and reminders to complete the questionnaire and inform prize winners. This data cannot be linked to the answers provided in the questionnaire. Names and addresses will be erased three months after completion of the monitor.

3.2 What about privacy?

We will of course process your answers with the utmost care. Your privacy is protected as a participant in this study in accordance with the General Data Protection Regulations (GDPR). This means that the collected data will be handled and processed in strict confidence. We are not interested in information on individual persons. The research results will only present data on the total group of residents aged 18 and over or subgroups such as the elderly or young people. We will not present any results on individual persons, and your answers will therefore never be published. Would you like to know more about how we handle the privacy of participants? Read our privacy statement.

3.3 How did you obtain my name and address?

Every resident in the Netherlands is registered with their municipality. Municipalities are required by law to provide official government agencies with information from the municipal population register. For the GGD Health Monitor Adults and Eldery 2024, Statistics Netherlands (CBS) received data from the municipal population register. Using this data, CBS selected persons for participation in the GGD Health Monitor Adults and Eldery 2024 at random, who are therefore representative of the population. This group of residents has been sent an invitation to fill in the questionnaire.

3.4 How can you check whether I have filled in the questionnaire?

For the online questionnaire, the login code is registered so that the computer can see whether or not you have completed the questionnaire. For the paper copy of the questionnaire, a bar code is printed on every page, which is read by the computer. These bar codes and login codes are compared with the list of participants, based on which reminders are sent out. Note that all address data will be erased once the monitor has been completed.

3.5 Do other people know what I have filled in?

We only use your name and address to send the invitation and the reminders and to inform prize winners. The data file containing the names and addresses is not linked to your answers and will be erased on completion of the monitor. The research results only describe the total group of residents aged 18 and over or subgroups such as the elderly or young people, and not individuals. Your individual answers will therefore not be published. Would you like to know more about how we handle the privacy of participants in this study? Read the privacy statement.

3.6 How is my privacy guaranteed when data is combined with other data?

The answers provided in this monitor are combined with information sent to CBS by other organisations, such as data on income and population composition. As a result, the GGD can reduce the number of questions in the questionnaire. No person can be identified in the aggregated information that GGDs receive from CBS. With the combined data, CBS can also weigh the results of the GGD Health Monitor. Weighing is necessary to ensure that the participants are a good reflection of the population. Population groups that participated relatively little are then counted more heavily in the results. Groups that have participated relatively often are counted less heavily. Every participant is assigned a unique number, based on which the data is combined. This is an automated process in which no personal information such as name and address is used.

4. Topics covered in the questionnaire

4.1 Which topics does the questionnaire deal with?

The questionnaire deals with the following topics

4.3 I would like more information about one or more topics in the questionnaire, is that possible?

Yes, that is possible. If you fill in the questionnaire online, you will see a page at the end of the questionnaire listing websites where you can find more information on the topics in this questionnaire.

5. Monitor results

5.1 What will the monitor results be used for?

Municipalities will use the monitor results to develop health policy. Municipalities and the GGD may also use the results to organise specific activities to improve the health and well-being of local residents.

5.2 Where can I find the results of the monitor?

The monitor results will be published in mid-2025 on the CBS Statline, RIVM Statline, VZinfo (RIVM) and GGD websites. The results will only present data relating to the whole group of participants aged 18 and over or subgroups, such as the elderly or young people. We will not present any results relating to individual persons, and your answers will therefore not be published.
