  • The Link Between Personality, Global, and Domain-Specific Satisfaction Across the Adult Lifespan (PDF, 537KB)

WASHINGTON — Certain personality traits are associated with satisfaction in life, and despite the changes people may experience in social roles and responsibilities over the course of their adult lives, that association is stable regardless of age, according to research published by the American Psychological Association.

“Many studies have shown that people with certain personality profiles are more satisfied with their life than others. Yet, it had not been extensively studied whether this holds true across the lifespan. For example, extraverted—that is sociable, talkative—people might be particularly happy in young adulthood, when they typically are forming new social relationships,” said study co-author Gabriel Olaru, PhD, an assistant professor at Tilburg University. “We thus wanted to examine if some personality traits are more or less relevant to life, social and work satisfaction in specific life phases.”

The research was published in the Journal of Personality and Social Psychology.

To determine how the relationship between personality traits and life satisfaction changes over time, researchers analyzed data collected from 2008 to 2019 by the Longitudinal Internet Studies for the Social Sciences (LISS) panel survey, a nationally representative survey of households in the Netherlands. Over 11 years, 9,110 Dutch participants ranging from 16 to 95 years old at the time of the first survey answered multiple questionnaires to assess their Big Five personality traits—openness, conscientiousness, extraversion, agreeableness and emotional stability/neuroticism—and their satisfaction with their social connections and their life overall. Only the 5,928 participants who were employed at the time of the survey also answered questions about their satisfaction with their work lives.

The researchers found that most of the relationships between personality traits and satisfaction remained the same across the adult lifespan, and that emotional stability was the trait most strongly associated with people’s satisfaction with their life, social connections and career.

“Our findings show that – despite differences in life challenges and social roles – personality traits are relevant for our satisfaction with life, work and social contacts across young, middle and older adulthood,” said Manon van Scheppingen, PhD, an assistant professor at Tilburg University and another co-author on the study. “The personality traits remained equally relevant across the adult lifespan, or became even more interconnected in some cases for work satisfaction.”

The researchers also found that different personality traits were related to people’s satisfaction with their social lives and careers—most notably conscientiousness for work satisfaction, and extraversion and agreeableness for social satisfaction. People who saw increases in these traits across time also reported increases in their life, social and work satisfaction.

People’s satisfaction with their work was the most affected by differences in age. As participants in the study aged, the relationship between career satisfaction and emotional stability grew moderately stronger.

Despite a weaker correlation between openness and life satisfaction overall, the researchers found that people who increased in openness also increased in life satisfaction across the 11 years measured by the LISS survey. This relationship may be explained by indirect processes, according to the researchers.

“Emotional stability likely shows a strong link with global and domain-specific satisfaction because this trait colors people’s general view of the world,” Olaru said.

“A good example of how personality interacts with the environment can be found in the work context. One of our findings was that the link between emotional stability and work satisfaction increases across age. This might be explained by the fact that emotionally stable people are less scared to quit unsatisfactory jobs and more likely to apply for jobs that are more challenging and perhaps more fulfilling and enjoyable in the long run,” van Scheppingen added.

Future studies should examine how variables that change with age, such as income, employment status, marital status and health, affect the relationship between personality traits and overall satisfaction with life, according to the researchers.

“While we did not examine what caused these changes, [the research] shows that our personalities and our happiness are not set in stone,” van Scheppingen said. “Perhaps we may even be able to influence how we change: If we try to become more organized, outgoing, friendly, this might increase life, social or work satisfaction as well.”

There are a number of healthy foods that you should eat daily because they are beneficial to your health. This also includes a very specific type of chocolate, for example. We introduce you to 6 foods that should have a permanent place on your menu and that can be easily integrated into various dishes. Of course, you don’t always have to eat the same thing- a balanced diet is crucial. The following foods you should always have in your kitchen, and they are also really tasty.

These Are The 6 Foods You Should Eat Every Day

Green Tea

Whether for breakfast or in between: green tea makes you awake and fit. The caffeinated drink is an alternative for all non-coffee drinkers. The postive effects of green tea have already been proven by numerous studies. One reason for this is the catechins contained in green tea. These are secondary plant substances that have an antioxidant effect in the body. That means they prevent so-called “free radicals” from damaging the DNA.

Nuts

Nuts are the perfect snack for in between. Nuts contain many important nutrients and healthy fats, and thus keep you fit. A handful of nuts a day can protect you from heart attacks and strokes. The performance of the brain is also positively influenced. Nuts are ideal as an addition to your muesli or salad.

Raspberries And Blueberries

The small snack for in-between tastes not only great but also has an important added value: The fruit is considered to be detoxifying and beneficial for digestion. Raspberries also contain antioxidants that can slow down skin aging and reduce the risk of cancer. In addition, berries are extremely low in calories and sugar.

Oats

As a delicious addition to a smoothie, baking or muesli: Oat flakes are healthy food for everyday life. They contain fiber, valuable vitamins, minerals and at the same time little fat. The fiber, in particular, will keep you full for a long time and get you through the day well. Oatmeal can also help with gastrointestinal problems. As a healthy snack between meals, oat biscuits are highly recommended!

Apples

“One apple a day keeps the doctor away” – this is by no means a myth. Apples not only strengthen the immune system, they are also high in fiber, flavonoids and polyphenols. These clean your body of metabolic toxins. The miracle fruit is also said to help with constipation and diarrhea. It is best to eat apples with their skin on- this is where most of the nutrients are. With 54 calories per 100 grams, the apple is also low in calories and perfect for a snack in between meals or for morning muesli. Make sure to wash the apple thoroughly beforehand.

Dark Chocolate

Surprised? You can also eat chocolate every day – but this refers to dark chocolate with no added sugar. The treat is actually a health booster: cocoa is a source of antioxidants and improves your mental performance. Chocolate is suitable as a snack between meals or as a dessert.

How To Keep Yourself Healthy In The Winter

Keeping yourself happy and healthy is important 12 months out of the year, but it becomes a bit more challenging to keep up with normal health routines around the holiday season, especially if you live somewhere that gets cold and gloomy throughout the few winter months. You can’t go out as often because of the weather, and it seems to constantly be dark outside. All of these difficulties add up quickly to create a hard time from November through February. We’re here to give you some tips on how to make these months a little less stressful on your everyday lifestyle.

How To Keep Yourself Healthy In The Winter

Eat Even More Fruits And Vegetables Than Normal

In the winter months it can be very easy to use the holidays as an excuse to forget about your healthy eating habits and eat all of the cookies and mashed potatoes that come your way, but we promise you will feel much better if you are more conscious about how many fruits and vegetables you eat throughout the day as well. Of course, eating sweets and unhealthy foods is perfectly okay, but don’t let that become the staple of your diet. Many people forget that their health is still on the line when it’s holiday time, but don’t let yourself become one of those people. Incorporating fruits and vegetables into food items at the dinner table, like eating a side of carrots or broccoli with your mashed potatoes, can be a good way to get the best of both worlds this season.

Take Vitamin D Supplements

Vitamin D is one of the vitamins that is less-frequently spoken about but needs to receive just as much attention as anything else. Vitamin D is produced naturally by your body when your skin interacts with the sun, which is why people who live in climates that get cold tend to become vitamin D deficient when it’s winter. When you interact with the sun, your body produces vitamin D which has many health benefits, including strong bones and a rockstar immune system. Vitamin D deficiencies can make you feel weak and fatigued, and that is the last thing you want during the winter when you already just want to stay inside and sit by the fire all day.

Don’t Become A Couch Potato

Despite the fact that the air is frigid and the ground is full of snow or ice, try to do one thing every day that will get you up onto your feet and moving around. Instead of spending your whole weekend in bed, try to go to sleep and wake up at the same time each day; this will help your body keep up with its routine of getting up and doing something as you would during the week. Whether it’s taking up winter sports, taking a brisk walk around the block, or just going to the grocery store and back, getting outside and doing something– and seeing the natural sunlight– will do wonders for both your physical and mental health.
