Subjective cognitive change in healthy community-based young and midlife adults: a comparison to those with mild
1Melbourne School of Psychological Sciences, The University of Melbourne, Victoria, 3010, Australia. jfande@unimelb.edu.au.
Background:
There is a paucity of research examining subjective cognitive change in healthy young and midlife (Y/ML) adults.
Objective:
The aim of this study was to compare subjective cognitive change (both improvement and deterioration; SCC) between healthy Y/ML adults and individuals with mild traumatic brain injury (mTBI) and investigate factors that may be associated with SCC in YML adults.
Method:
The sample comprised 111 healthy Y/ML adults and 72 age-matched individuals with mTBI who completed measures of SCC, psychological status and objective cognitive function.
Results:
Analyses revealed that 81% of Y/ML adults believed their cognition was no different or better than 4 weeks prior, compared to only 41% of the mTBI group. There was no robust linear association between any measure of cognition or psychological status and SCC in the Y/ML adults (p>.05).
Conclusions:
Many healthy Y/ML adults believe their cognition to be improving over time, at least somewhat (34%).
