What does Kelly suggest is a vital part of an individual's psychological health?

Kelly emphasizes that psychological health is significantly influenced by an individual's ability to reassess and adjust personal constructs. In his Personal Construct Theory, personal constructs are the mental frameworks through which individuals interpret and predict future events based on past experiences. The flexibility to modify these constructs in response to new situations is crucial for adapting to the ever-changing nature of life.

When individuals are open to reassessing and adjusting their constructs, they can better navigate complex environments and relationships, leading to healthier interactions and improved coping strategies. This adaptability fosters resilience and enhances a person's capacity to understand themselves and the world around them. Therefore, the ability to rethink and refine personal constructs is a cornerstone of psychological well-being according to Kelly's theory.
