Investigating the content validity and the simultaneous validity of “Working Memory Training Software” with the subtests of working memory in “Tehran- Stanford-BinetIntelligence Scale” and “Wechsler intelligence scalefor c hildre n”

The aim of this study is examining the psychometric properties of “Working Memory Training Software”. This research is applicable, a kind of constructing instrument and based on construction and validation of “Working Memory Trai ning Soft ware”, and it is performed in a semi-experimental design. Its data were collected from the 115 students of the third grade (45), fourth grade (54), and fifth grade (16) of pri mary school. The software content validit y was specified by asking expertise opinionsand investi gating these opi nions through Spearman Test (rs=1). “Worki ng Memory Training Soft ware”, the subtests of worki ng memory in “Tehran- Stanford BinetIntelligence Scale” and “Wechsler intelligence scale for children” was conducted in all three groups. due to The Pearsoncorrelation coefficient there is a relation between the numbe r of children’s correct responses in plays of the software and the score of the Wechsler s cales working memory (rp=0.809) and the s core of Binet scale worki ng memory (rp=0.864).Hence the “Working Memory Trai ning Software” has a proper content validit y and also has simultaneous validit y with the subtests of working memory i n “Tehran- Stanford-BinetIntelligence Scale” and “Wechsler intelligence scale for children”, and it has proper psychometric properties.
