How To Find Matching and Common Items in Questionnaires and Surveys

When researchers take on the task of analysing data from surveys and questionnaires, they often encounter a significant obstacle: finding matching or common items across different sources. This challenge is due to the many different ways questions are asked or formatted. This makes it tough to compare and merge data effectively.

According to Forbes, researchers spend up to 80% of their time just getting data ready for analysis, and a big part of that time goes into harmonising data.

The harmonisation of questionnaire data, therefore, becomes an important aspect of research. This is especially true when you’re striving for high data accuracy and comparability (as you should).

Achieving a harmonious dataset means researchers can draw reliable connections and conclusions across different studies and this boosts the credibility and impact of their work. But how do you make it happen? Let’s talk about it!

Top 3 Strategies for Finding Matching Items

1. Define Your Objectives

Identifying the objectives behind harmonising questionnaire data is an important first step that shapes the entire harmonisation process. This involves pinpointing exactly what you hope to accomplish by finding matching or common items across various questionnaires. Your goals might vary, such as:

  • Amalgamating datasets from different studies to draw more comprehensive conclusions.
  • Contrasting results from distinct research efforts to uncover unique insights.
  • Detecting consistent patterns or trends that emerge across multiple data sources.

Understanding your research goals clearly is vital as it shapes your approach to harmonising data. It helps you identify the essential questions driving your research outcomes and decide which datasets deserve immediate attention. Additionally, it can reveal specific challenges, like aligning differently worded questions that aim to uncover the same information or managing diverse response scales.

Example: Imagine a researcher who wants to analyse dietary habits across different age groups to identify trends in healthy eating. Their objectives might include:

  • Finding common dietary questions from various health surveys conducted over the last decade.
  • Comparing dietary trends between younger and older populations to identify shifts in eating habits.
  • Identifying consistent patterns in food preferences across different regions or socioeconomic groups.

This initial step of defining your objectives not only makes the journey smoother but also guarantees that every effort you put in directly boosts the accuracy, relevance, and impact of your findings. Establishing clear goals from the get-go builds a solid groundwork for a harmonisation process that’s not just efficient but effective. By doing this, you open up paths to deeper and more significant insights from your questionnaire data.

2. Identify Key Themes

Now that your objective is crystal clear, let’s move to step 2: identifying key themes. This step is just as important in finding matching items across different questionnaires.

How does it work? Well, this process often involves manually sifting through the data to spot common themes or similar questions.

There are two main strategies that can be used for effective organization and comparison: categorization and thematic analysis. Let’s take a look at both data harmonisation techniques and how they can be of help.

1. Categorization Technique

Begin by thoroughly examining each questionnaire and jotting down the principal topics or domains addressed by each query. Then, assign questions from different surveys to these identified themes. This organization helps you compare and align similar questions under unified themes.

For example, let’s say you have three different questionnaires on health and lifestyle. By categorising, you might find common themes such as “Dietary Habits,” “Physical Activity,” and “Mental Health.” Questions from each survey that ask about participants’ exercise routines can be grouped under “Physical Activity,” despite variations in wording or response options.

2. Thematic Analysis

This technique goes deeper. Even if questions are phrased differently across surveys, they may still aim to collect data on a singular theme, like “Customer Satisfaction” or “Employee Engagement.” Thematic analysis enables you to cluster these questions together based on their informational goals, not just superficial similarity.

To visualize the process, imagine analysing surveys from different companies about workplace satisfaction. Despite different phrasings, you notice a recurring intent to measure “Work-Life Balance.” Questions like “How often do work demands interfere with your personal life?” and “Are you satisfied with your current work-life balance?” — though different — both seek insights on the same theme and can be analysed together.

Which Method Should You Use?

Both these methods require a detailed review of the questionnaires and a deep understanding of the research objectives (step 1).

They also demand a level of subjectivity and judgement from the researcher, as deciding which questions are similar enough to be considered “matching” can sometimes be a nuanced decision.

3. Using Software Tools to Find Common Items

When working with surveys and questionnaires, finding questions that match or are similar can be tough. This is because each survey might ask questions in different ways. To make this easier, some software tools can help. These data harmonisation tools look through the text to find questions that are either exactly the same or have a similar meaning.

A great tool for this job is Harmony, our very own project. Harmony is special because it uses something called Natural Language Processing (NLP) to compare questions from different surveys. This is really useful if you’re working with surveys in more than one language or if you’ve got different versions of the same survey.

Harmony can check if questions are the same, kind of the same, or even opposites. It’s designed to make research easier by making sure you can compare data accurately, no matter where it comes from. You can use Harmony right from your web browser, or if you prefer coding, there’s a version for Python and R, too.

We’ve made Harmony with the idea that it should be easy for anyone to use, no matter if you’re a researcher at a university or someone working on your own project. We’re all about making your data work better for you and helping you to spot connections you might miss otherwise.

Whether you’re dealing with surveys in English, Portuguese, or any other language, Harmony is here to help you find those matching and common items quickly and accurately. It’s about making your data more reliable, so you can focus on what really matters in your research.

A Holistic Approach to Data Harmonisation

Clearly, finding ways to match up items from different sources is a significant challenge for researchers. The variety in how questions are asked can really complicate trying to line up and combine data. It shows just how important it is to have effective ways to harmonise data.

Achieving a high level of data accuracy and comparability is key, as it lets researchers draw solid connections and conclusions. It improves the quality and reliability of their findings, as you probably know very well. But do you know just how much of a problem unharmonised data poses? Well, a 2021 study in the Journal of Data Science pointed out that efforts to harmonise data could save the global research community millions of dollars every year by cutting down on unnecessary data gathering and making existing data sets more useful.

Using the right data harmonisation tools, having a thoughtful approach to survey design, and an openness to collaboration and learning from the research community are all equally vital. Researchers should:

  1. Start with Clear Objectives: Before starting with data collection, be clear about what you want to achieve. This clarity will guide your questionnaire design and make it easier to harmonise data later on.
  2. Engage with the Community: Utilise platforms like Harmony’s Discord community to share experiences, seek advice, and find collaborators. Engaging with others can provide new insights and methods for your data harmonisation process.
  3. Embrace Technology: Tools like Harmony are there to simplify the process. Take advantage of these resources to save time and improve the accuracy of your data analysis.
  4. Prioritise Learning: Stay informed about the latest in survey methodology and NLP technology. Continuous learning can help you refine your approach to harmonising data.

The task of harmonising questionnaire data, though it can seem scary at first, is essential for elevating research outcomes. Let’s not view harmonised data as just a hurdle but as an opportunity to deepen our understanding of data and create more reliable and impactful research findings.

Frequently Asked Questions

We know you might have some questions on your mind – either about our tool Harmony or about how to find matching and common items in questionnaires and surveys in general. We’ve got the answers:

What sets Harmony apart from other tools?

Harmony uses advanced technology called Natural Language Processing (NLP) to understand and compare the text of survey questions. This tech allows Harmony to see not just the obvious matches but also to find questions that are similar in meaning. Think of it as having a really smart assistant who can read through thousands of questions and spot the ones that are asking the same thing, even if they’re worded differently.

How do you compare survey results?

To use Harmony for comparing and matching survey items is straightforward and easy. Here’s a simple guide:

1. First, you gather the surveys or questionnaires you want to compare.

2. Then, upload them to Harmony.

3. Harmony will analyse the text, compare the questions, and show you which ones match or are similar.

It’s a bit like doing a puzzle, but Harmony finds the matching pieces for you.

How do you analyse a survey questionnaire?

To analyse a survey, first, you need to collect all the answers. This means getting information from folks who filled it out, using online forms, paper sheets, or asking them directly. If you’re thinking, “How do you gather information from a survey?” the trick is to use a mix of these ways to make sure you don’t miss out on any useful feedback. After you’ve got all the data, sort it out. Look for patterns in the choices people made or dive into their written answers to see what they’re really saying. Using a tool like Harmony can make this much easier and help you spot what’s important quickly.

What are the methods of data collection in a questionnaire?

There are a few main ways to collect data with a questionnaire: online, on paper, or through an interview. Online questionnaires are quick and can reach lots of people fast. Paper ones are good for when you can’t use the internet. Interviews let you ask more questions based on what someone says. Each method helps make sure you get a full picture of what people think or feel about your questions.

Can Harmony compare surveys in different languages?

Yes, Harmony can handle questionnaires in different languages! This is great for researchers working with data from various countries.

Data Harmonisation in Education

Data Harmonisation in Education

Data Harmonisation in Education: Overview The term ‘harmonisation’ has often been used in different contexts – for example, to describe similar phenomena, such as collaboration, coherence, alignment, integration, partnership, etc. However, we might argue that these concepts might do nothing more than indicate the extent and scale of integration among different entities when it comes to regional cooperation. Now, the underlying degree of interaction between all the players involved can run a lot deeper and tighter when we transition from collaboration, partnership, and cooperation to integration, community, harmonisation, and interdependence.
