Scientists identify a personality feature that could predict how often you exercise

September 20, 2019

Individuals who make concrete plans to meet their goals may engage in more physical activity, including visits to the gym, compared to those who don't plan quite so far ahead, research shows. These research findings, published in Psychological Science, a journal of the Association for Psychological Science, suggest that self-reported levels of a trait called 'planfulness' may translate into real world differences in behavior.

Some people seem to be able to more consistently meet their goals than others, but it remains unclear if personality traits that have been found to promote goal achievement in the lab similarly encourage individuals to achieve long-term goals in their day-to-day lives, says lead researcher Rita M. Ludwig of the University of Oregon.

Conscientiousness, a measure of individuals' orderliness and dependability on the Big Five Inventory of personality, has long been tied with healthy behaviors, notes Ludwig and colleagues Sanjay Srivastava and Elliot T. Berkman, also of the University of Oregon. Narrowing their focus to a single facet of this trait, planfulness, allows researchers to zero in on the psychological processes--such as mental flexibility, and a person's ability to make short-term sacrifices in pursuit of future success--that contribute directly to achieving long-term goals.

"There indeed appears to be a certain way of thinking about goals that correlates with long-term progress," Ludwig says. "What's new in this study is that we used an objective measure of goal progress that could be recorded as participants naturally went about their lives: their check-ins at a local gym."

Ludwig and colleagues examined this relationship by analyzing the gym attendance of 282 participants over a 20-week period. The researchers tracked the number of times each participant swiped into the campus recreation center after enrolling in the study at the start of the winter 2018 academic semester. They also retroactively collected data on gym attendance throughout the fall 2017 term.

The participants, many of whom were students, provided a written description of their exercise plans and completed measures of self-control and grit, in addition to the Big Five Inventory of personality and Ludwig and colleagues' 30-item Planfulness Scale.

While all participants experienced a similar decline in gym attendance over the course of each semester, individuals who rated themselves high on planfulness items such as "developing a clear plan when I have a goal is important to me" went to the gym more throughout both semesters compared to those who ranked themselves lower on planfulness. The researchers found that a one point increase on the five-point Planfulness Scale corresponded with an additional 5.9 recreation center visits during the fall semester, and an additional 8.5 visits after enrolling in the study for the winter semester.

Planfulness was only significantly associated with the frequency of participants' gym attendance during the winter semester, possibly due to participants completing their physical activity plan later in the year, the researchers noted.

"This work is broadly informative for those who are curious about how people pursue health goals, including their own patterns of thought around goals," Ludwig says. "Clinicians might find it helpful in understanding how their patients tend to think about goals and whether person-to-person differences in such thinking are related to outcomes."

While there was a small, but significant relationship between participant planfulness and the level of detail in their physical activity plans, descriptiveness was unexpectedly found to have no relationship with gym attendance, Ludwig and colleagues noted.

"It seems logical that people who are successful with their goals would be able to write in detail about their planning process," Ludwig says. "We were surprised, then, to find no relationship between people's goal pursuit behavior and how they wrote about their goals."

Future psycholinguistic research might investigate alternative explanations for these findings, the researchers conclude.

#537 Science Journalism, Hold the Hype
Everyone's seen a piece of science getting over-exaggerated in the media. Most people would be quick to blame journalists and big media for getting in wrong. In many cases, you'd be right. But there's other sources of hype in science journalism. and one of them can be found in the humble, and little-known press release. We're talking with Chris Chambers about doing science about science journalism, and where the hype creeps in.
