Competing factor models of cognition of healthy older adults: Support for SuperAgers identification

Objectives. Neuropsychological tests employ several cognitive functions to a different extent. Thus, factor structures of various neuropsychological batteries and their analyses show both similarities discrepancies. The study explores the Czech comprehensive battery for SuperAgers (older people with excellent cognition) from cross-sectional longitudinal point view in respect its structure stability over time.Sample settings. sample consisted 361 healthy older adults (age 60–94) assessed years 2012 2015 battery.Statistical analyses. Data were analyzed confirmatory invariance time using multiple competing theory-driven models cognition based on previous studies consisting 1–5 factors.Results. results that best fitting model consists four factors: verbal memory, attention/working executive functions, language. also suggest factorial was most stable. This reflects functioning highlights need identify basis performance domains. authors propose these domains should be taken into account identifying comparing standard procedure future studies.Limitations. visuospatial or nonverbal memory factors not represented our relevant tests. Our adults.
