Everyday problem solving in older adults: observational assessment and cognitive correlates

Area of Science:

• Gerontology
• Cognitive Psychology
• Psychometrics

Background:

• Assessing everyday problem-solving skills in older adults is crucial for maintaining independence.
• Existing measures may not fully capture the complexity of practical problem-solving in daily life.

Purpose of the Study:

• To introduce and validate the Observed Tasks of Daily Living (OTDL), a new measure for assessing everyday problem-solving in older adults.
• To examine the relationship between everyday problem-solving, cognitive abilities, and demographic factors in older adults.

Main Methods:

• Development and validation of the Observed Tasks of Daily Living (OTDL) measure.
• Correlational and path analyses to investigate relationships between OTDL performance, cognitive abilities (fluid and crystallized intelligence, perceptual speed, memory span), age, education, and health.

Main Results:

• The OTDL demonstrated internal consistency and convergent validity, identifying three distinct factors of everyday problem-solving.
• Older adults' OTDL performance was linked to basic mental abilities, with age directly and indirectly impacting problem-solving via cognitive abilities.
• Education and health influenced everyday competence indirectly through cognitive abilities, with perceptual speed and memory span mediated by fluid and crystallized intelligence.

Conclusions:

• The Observed Tasks of Daily Living (OTDL) is a reliable and valid instrument for evaluating practical problem-solving skills in older adults.
• Cognitive abilities play a significant mediating role in how age, education, and health affect everyday competence in older populations.
