Abstract

Introduction: The Memory Complaint Scale (MCS-15) is a 15-item instrument to explore frequent forgetfulness in daily life in people with possible cognitive impairment. However, knowledge about its psychometric performance is limited. Objective: The objective of this study was to know the dimensionality and internal consistency of the MCS-15 in Colombian older adults. Methods: A probabilistic sample of 1,957 older adults from the general Colombian population was taken, aged between 60 and 98 years (mean = 71.0 ± 7.9), and 62.2% were women. Internal consistency (Cronbach’s alpha and McDonald’s omega) and dimensionality (exploratory and confirmatory factor analysis) were calculated for the original and ten-item versions. Results: The 15-item version showed Cronbach’s alpha and McDonald’s omega of 0.91, and one dimension accounted for 45.3% of the variance. A version of ten items showed Cronbach’s alpha and McDonald’s omega of 0.89 and a single factor that explained 50.9% of the variance with better indicators in the confirmatory factor analysis. Convergence with the shortened Mini-Mental State Examination was rs = 0.43 (p < 0.001), and the Montreal Cognitive Assessment test was rs = 0.38 (p < 0.001). The nomological validity with the geriatric depression scale was rs = 0.44 (p < 0.001), and women scored higher than men (p < 0.001). Conclusions: The MCS-15 shows high internal consistency with poor dimensionality. However, a ten-item version shows high internal consistency and a clear one-dimensional structure. More research is needed: testing the performance against a structured interview for major cognitive impairment.
