The psychological nature of subjective memory complaint in non-demented older adults: The respective predictive values of psycho-affective,lifestyle, and cognitive inhibition variables

Introduction/ObjectiveThe aim of this study was to investigate, using path analysis (Lisrel 8.52), the relationships between subjective memory complaint and cognitive inhibition, lifestyle, and psycho-affective variables on a sample of non-demented older adults.MethodOur sample was composed of 109 older adults, who were required to undertake two cognitive inhibition tasks (stroop and verbal fluency) and to respond to scales designed to measure individuals’ psycho-affective status (depression/subjective health) and subjective memory complaint level (Mac Nair). Lifestyle predictors (education and activity levels) were also assessed.Results/ConclusionThis study highlights the importance of adopting a multifactorial approach to the study of subjective memory complaint. In addition to executive variables (verbal fluency task), predictors such as subjective health and activity levels seem to be crucial in our understanding of the psychological nature of subjective memory complaint.
