Posttraumatic growth (PTG) is a valid concept, supported by cognitive functioning. Executive functions specifically predict PTG, suggesting a targeted relationship rather than general cognitive ability.
Area of Science:
- Psychology
- Neuroscience
Background:
- The concept of posttraumatic growth (PTG) describes positive personal changes following adversity.
- Despite evidence, the scientific validity of PTG remains debated.
- Objective cognitive measures have not been previously linked to PTG.
Purpose of the Study:
- To investigate the scientific validity of PTG using objective cognitive function measurements.
- To explore the relationship between specific cognitive functions and PTG in earthquake survivors.
Main Methods:
- Assessed cognitive functions (executive functions, memory, processing speed) in earthquake survivors.
- Correlated cognitive function scores with measures of posttraumatic growth.
Main Results:
- Executive functions significantly predicted PTG.
- Memory and processing speed were not associated with PTG.
- Personal growth, a facet of PTG, correlated with cognitive functions, unlike relational growth.
Conclusions:
- Findings support the scientific validity of the PTG construct.
- The specific link between executive functions and PTG suggests a targeted cognitive basis.
- Differentiates between facets of PTG, highlighting personal growth's cognitive ties.
