Psychometric characteristics of Memory Scale: Measure of everbody functions of memory in students

The purpose of this study was to examine psychometric characteristics of memory scale: measure of everbody functions of memory in students. The research design is a correlation type. The population of this study is all students of elementary schools in Semnan city. 220 students were selected by cluster random sampling method and their parents responded to the memory scale (Geurtin et al., 2018). SPSS-22 and Lisrel 8.54 were used for data analysis, Cronbach's alpha coefficient, multivariate analysis of   variance and rock curves. In the context of construct validity there was a significant difference between the two groups; normal students and students with learning disabilities in all components of memory; effortful/intentional learning, automatic/procedural learning, working memory and prospective memory/organization. In the context of the discriminant validity, the levels below the rock curve for each component showed the ability to differentiate between normal students and students with learning disabilities. The memory scale has an internal consistency and a good stability coefficient. The results of the factor analysis showed that this scale was made up of four factors of effortful/intentional learning, automatic/procedural learning, working memory and prospective memory/organization. Cronbach's alpha for effortful/intentional learning was 0.86, prospective memory/organization of 0.77, working memory 0.70, and , automatic/procedural learning 0.82 and for the whole scale 0.93. Findings of the research indicate that the Persian version of the memory questionnaire in the students’ community has acceptable psychometric properties.
