Abstract
INTRODUCTION
Views of aging have been linked with many important outcomes in older adults. Subjective cognition, or one's perception of their cognitive functioning, may be a valuable indicator of cognitive changes as individuals age, but is known to be impacted by a variety of factors. The aim of this systematic review was to synthesize the evidence on relationships between views of aging and subjective cognition, including whether and how these relationships may differ based on age.
METHODS
Guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria, we conducted a comprehensive literature search in four databases: PubMed, CINAHL, PsycINFO, and ProQuest Dissertations and Theses. Critical appraisal utilized the Critical Appraisal Skills Programme (CASP) checklists. Twenty sources (including 21 studies) met inclusion and exclusion criteria, from which data were systematically extracted and results narratively synthesized.
RESULTS
Seventeen out of the 21 identified studies (81%) found a relationship between more positive views of aging and better subjective cognition; however, some studies reported mixed results based on the domain of aging views. Domains that were consistently associated with subjective cognition were subjective age, attitudes toward one's own aging, aging well, and essentialist beliefs about aging. Only three studies reported age group differences or changes in associations over time, precluding conclusions about differences across middle- and older ages.
CONCLUSION
Most studies supported associations between views of aging and subjective cognition. More longitudinal as well as qualitative research is needed to advance understanding of factors that influence these relationships.
