Repetitive negative thinking is associated with subjective cognitive decline in older adults: A cross-sectional study
BMC Psychiatry Oct 14, 2020
Schlosser M, Demnitz-King H, Whitfield T, et al. - In a cross-sectional online survey, researchers sought to explore the connection between subjective cognitive decline (SCD) and repetitive negative thinking (RNT) along with other proposed psychological risk or protective factors for dementia and cognitive decline. Four hundred ninety-one older adults (mean = 64.9 years; 63.1% female) completed measures of RNT, personality traits, purpose in life, worry, rumination, and meditation practice in the online survey. Of the respondents, 24.2% of them reported complaints about memory. The theoretical relation between SCD and RNT is empirically corroborated by this analysis. To ascertain if RNT is a prodromal symptom or an independent risk factor, longitudinal studies are needed. Also more study is required to determine if RNT can be a promising construct for future research on the risk of SCD and dementia.
