Construct Validity of the Bruininks-Oseretsky Test of Motor Proficiency–Short Form for a Sample of Greek Preschool and Primary School Children

Abstract

The construct validity of the short form of the Bruininks-Oseretsky Test of Motor Proficiency for the assessment of gross and fine motor skills was assessed in 377 nondisabled Greek preschool and primary school children (age range 5 yr. to 8:3 mo.) from urban areas of northern Greece. Analysis showed the three factors accounted for 54.1% of the total score variance, agreeing with the earlier findings. Moreover, the item scores had statistically significant relationships with the total short-form score, except for that of copying a circle with the preferred hand. This latter item was also the only one with a small effect size. Age confirmed a statistically significant effect on the scores of the half items of the test battery, also an earlier finding. This test seemed to be a valid test of motor proficiency in normal Greek preschool and primary school children.
