neuroticism

"We estimate a shift in neuroticism and conscientiousness at the population level," McFarland said.

Similarly, those characterized by higher conscientiousness, openness, and agreeableness, as well as lower neuroticism and extraversion, were also more likely to adopt healthier behaviors.

For example, research shows that women who are higher in neuroticism and perfectionism, lower in self-compassion or lower in self-efficacy are all more likely to struggle with negative body image.

But grandiosity is associated with being assertive and attention seeking, whereas vulnerability tends to involve neuroticism and suffering from anxiety, depression and self-consciousness.

Conscientiousness, for instance, was associated with higher scores in the study conducted by Maertens and his team, while neuroticism and narcissism were associated with lower scores.
