How a fixed mindset about personality is related to depression and psychological distress

Previous studies suggest that there is an association between a fixed mindset about personality and internalizing symptoms such as depression and psychological distress. To what extent does this relationship indeed exist and how might it come about?

Fixed mindset and depression and psychological distress 

Studies suggest that adolescents with a fixed mindset about personality are more likely to report internalizing symptoms during the socially stressful transition to high school. 
A fixed mindset about personality (also called an entity theory about personality means: the belief that people cannot change their traits. Internalizing symptoms here mean: depressive symptoms and psychological distress. How can a way of thinking be related to feeling

Research SEO et al. 

Seo et al. (2021) investigated whether this relationship between mindset and internalizing problems indeed occurs and what underlying mechanisms are behind it. 
They conducted two studies. In their first study, they integrated several data sets (N = 6,910) and found that a fixed mindset is indeed associated with internalizing symptoms. 
Then, in their second study, they looked for mechanisms that could explain this association. In their study, they used 8-month longitudinal data and 10-day diary entries during the stressful freshman year of high school (N = 533, 3,199 daily records). 


The results showed that a fixed mindset of personality predicted an increase in internalizing symptoms through two factors: 
  1. the tendency to make fixed trait causal attributions about the self: for example, after a negative event, the child may think, “This is happening to me because I'm not likeable.” 
  2. maladaptive stress assessments: the child's assessment that he or she does not have the capabilities to deal effectively with the negative event or stressor. 
Factor 1 says "this is where it comes from" and factor 2 says "this is why it will continue to bother me." The figure below illustrates this: 

Practical implications 

These results suggest that it is wise to introduce children early on to the idea that people can change. In other words, by teaching them a growth mindset about personality
As parents and educators, we can teach children that personal characteristics do not have to be fixed, but can be changed. 
This might help to reduce the likelihood that the children will develop depressive symptoms and psychological distress.
