Real-world problem solving and quality of life in older people.
OBJECTIVE
This study examined relationships between quality of life (QoL) in older people and cognitive functioning in both abstract and real-world problem solving.


METHODS
Contributions of levels of mental, physical and social activities, self-rated and objective health status, self-rated cognitive functioning, socio-economic status, gender, real-world and abstract problem solving were examined in a regression study of factors related to QoL in older people.


METHODS
Participants (N=145) were 70-91 years of age. The current cognitive functioning was assessed by psychometric tests and real-world problem-solving tasks. Prior functioning was indexed by crystallized ability measures. QoL was assessed using the Leiden-Padua questionnaire (LEIPAD), Faces scales and Hospital and Anxiety Depression Scale. A single QoL factor was derived.


RESULTS
Simultaneous multiple regressions indicated that QoL was related to real-world but not to abstract problem-solving ability. Separate contributions to QoL were also found for health and self-rated cognitive functioning.


CONCLUSIONS
The present study replicates previous findings that abstract problem-solving ability is not related to QoL and supports the hypothesis that real-world or everyday problem-solving ability is associated with QoL in older people.
