What Is the Operational Definition of Happiness?

There isn’t just one way to describe happiness in the real world. Psychologists believe that happiness can be measured or found based on a number of factors that a researcher or data analyst decides are enough to measure happiness. For example, a researcher may decide that smiling is a sign of happiness and that the number of smiles people make over a certain amount of time can be used to measure happiness. To better understand how this idea applies to research in psychology and other social science fields, it helps to learn more about what operational definitions are, what they look like, and what their pros and cons are.

What Do Operational Definitions Mean?

In simple terms, operational definitions are parameters that tell you how to measure or find something when you’re gathering data. They are often used in research related to psychology, sociology, and other social sciences, and most of the best studies in these fields use them in some way. This is because operational definitions are concrete and measurable, which means they are clear and can be counted. This helps gather data in a meaningful way. Operational definitions are important because they say how a researcher will measure a variable in a study. They are descriptions of how a researcher will define and keep track of the variables. Variables are always changing, so it’s important to know exactly what they are and how they will be measured. This can help the researcher make sure that the data they are collecting are relevant to the study and are good indicators of whatever they are measuring to see if their hypothesis is right or wrong.

A variable, like an action, is always and clearly defined by the operational definition. It doesn’t give a number or score, which is what a value is. Variables can take on values. An operational definition tells how those values could be used to measure variables.

Anxiety Is Used as an Example

To understand operational definitions better, it can help to look at a concept and think about how it can be seen and measured, or “operationalized.” Imagine that you are studying anxiety, which is a feeling that everyone knows. You know from having anxiety yourself that it can show up in ways that other people can see, like shaking, sweaty palms, and a cracking voice. It can also make someone want to run away from the thing that’s making them anxious. You also know that anxiety can cause things like racing thoughts or a tight chest that other people don’t notice. All of these things are signs of anxiety.

Now that you know what the variables are, it’s time to make your operational definition or decide how you’ll measure people’s anxiety in your study. If you want to measure based on outward signs, you could make an operational definition that involves counting the number of signs people show or watching to see if they leave or stay in a stressful situation. People could wear heart rate monitors to find out when their pulses speed up as an internal sign. Or, you could make a survey or questionnaire and ask people to rate their own anxiety on a scale. No matter how you choose to measure anxiety, the act of deciding how you’ll measure it is the same as making your operational definition.

When to Use Operational Definitions and When Not to

One of the best things about operational definitions is that they make it clear whether or not a study is valid. This means that they help researchers figure out if they measured what they set out to measure during their study. Operational definitions also make it easier to understand the different parts of a study. This makes it easier for other researchers to understand a study and possibly repeat the results because the variable was defined clearly enough that other researchers can set up a similar study and measure similar results.

There are some bad things about using operational definitions that you should think about. One of the biggest is that if you use operational definitions, you can choose how to measure something based on what you know. You could be making an assumption about how the operationalization works, or there could be something else that makes your choice wrong. The definition you make could change how you see and think about data, which could lead you to misrepresent those data.

Let’s go back to the beginning as an example. Say you want to know how happy people are. You think that people smile more when they are happy, so you count smiles to test your theory. This is how you’ll measure the variable, happiness. It’s your operational definition. You also set other parameters, like a time limit, like how many times happy people smile in an hour. This sounds like a good idea, but counting a person’s smiles isn’t a good way to figure out how happy they are. People are more likely to smile for social reasons, like in response to another person’s smile or when they feel embarrassed, than because they are happy. In this case, you made a guess that the operationalization was a good way to measure, which will make it hard to figure out what your data means.
