Psychometric Battery “Multifactorial Investigation of Neuropsychological Development” (MIND)

Abstract

Background. Russian neuropsychology lacks a standardised set of methods for quantifying the development of higher mental functions (HMF) from pre-school to high school age. Its application could improve the objectivity of neuropsychological diagnosis. Objectives. The study seeks 1) to create a psychometric battery of methods for multifactorial investigation of neuropsychological development (MIND) in children and adolescents aged 4–17; 2) to describe the trajectories of age-related development of HMF. Study Participants. 860 participants aged 4–17 (M = 10; SD = 3.7), including 558 boys and 302 girls took part in the study. Methods. Neuropsychological assessment was performed using 40 techniques and measuring 171 variables. These variables were standardised and age-adjusted. Exploratory and confirmatory factor analysis was used to find latent variables. The resulting model was applied to age-unadjusted variables to identify developmental trajectories. Results. A model was built with 106 indicators and 21 factors. Four variables were used to construct an additional verbal-logical thinking scale. The general level of development can be reliably measured using 50 variables. These scales are described as age dependent. Conclusions. The MIND psychometric battery for neuropsychological assessment of children and adolescents aged 4–17 has been created. The quantitative evaluation is based on a mathematical description of the age-related development of HMF components.
