Abstract: ObjectiveSubjective cognitive decline (SCD) was frequently investigated for memory in healthy aging or in relation to diseases like dementia. It was found to be related to sociodemographic and psychological variables as well as cognitive abilities. The prevalence of SCD in other cognitive domains and their relation to these variables is largely unknown to date. The present study aimed to fill this gap.MethodsA total of 807 subjects (18‐85 years of age, M = 57.8 years, female: 43%) completed the Juelich Questionnaire on Subjective Cognitive Decline, to investigate SCD in memory, attention, language, motor, and executive functions. Logistic regression analyses were used to estimate association of depressive symptomatology, emotionality, and general cognitive performance as well as age, gender, and educational attainment with domain‐specific SCD.ResultsThe highest prevalence rate was obtained for the memory domain (65.9%), followed by the attention (54.6%), motor (52.9%), executive (39.7%), and language domain (31.5%). Of the psychosocial factors, only age, depressive symptomatology and emotionality were consistently and strongly associated with domain‐specific SCD prevalence.ConclusionsSCD is prevalent not only in the memory domain, but also in other major cognitive domains. Our results also suggest that the suspicion from previous research, that subjective memory decline might be more strongly associated with depressive symptomatology and emotionality than with actual decline of cognitive performance, might also apply to the attention, motor, executive, and language domain. Further investigations using neuropsychological testing for specific cognitive functions and employing longitudinal designs are required for substantiating this suspicion.
