MIDUS 2 Cognitive Project: Cognition and Biopsychosocial Factors

Over 7,000 Americans aged 25 to 74 were surveyed nationally in 1994/1995 as part of the Midlife in the United States (MIDUS) study. A longitudinal follow-up in 2004-2006 administered the Brief Test of Adult Cognition by Telephone (BTACT) to a sample including a core group (N=3,487), metropolitan oversamples (N=757), twins (957 pairs), and siblings (N=950). This dataset examines relationships between cognitive performance and biopsychosocial factors like SES, health behaviors, biomarkers, depression, and personality.

Use Cases

• Analyzing age-related differences in cognitive performance across multiple domains based on telephone-administered test scores.
• Investigating associations between socioeconomic status (SES) and individual differences in cognitive functioning.
• Modeling the impact of health-promoting behaviors and metabolic biomarkers on midlife cognitive health.
• Studying the longitudinal relationship between personality traits, control beliefs, and cognitive change.
• Examining the role of stressful life events in mental and physical health outcomes within a nationally representative sample.

Strengths

• The dataset is based on a large-scale, nationally representative sample of over 7,000 individuals.
• It provides longitudinal data with a follow-up wave conducted approximately 10 years after the initial survey.
• The cognitive assessment includes a validated telephone-administered battery (BTACT) covering multiple domains.
• It integrates a wide range of biopsychosocial variables, including biomarkers, psychosocial factors, and health behaviors.

Limitations

• Specific column names and the exact row count for the cognitive project subset are not provided in the source metadata.
• The dataset's freshness is unclear as the last update date is unknown across all platform entries.
• The provided descriptions are repetitive and do not detail the exact file formats or data structure.
