The Scale of Independent Behavior and Revised Vineland: A Comparison Study.
Middleton, Helene; And Others
The relationship between the Scales of Independent Behavior (SIB) and the Vineland Adaptive Behavior Scale (VABS) was investigated, with 53 children as subjects. Specifically, the study sought to examine the convergent and discriminant validities of the long forms of the SIB and the VABS and to ascertain the accuracy of classification of intellectually handicapped children using these two instruments. The subjects, aged 3 to 7, were classified as being behaviorally handicapped, communication disordered, slow learners, mildly intellectually handicapped, or moderately to severely intellectually handicapped. Analysis found evidence of convergent validity between the two instruments in the measurement of adaptive behavior. Scales measuring personal living skills exhibited excellent convergent validity and fair discriminant validity; communication skills scales exhibited good convergent validity and fair discriminant validity; and domestic skills and socialization skills scales exhibited poor convergent and poor discriminant validities. Motor skills scales had such low convergent validity that discriminant validity was not examined. Other variables critical in test selection were also examined, including administration time, interview format, interrater reliability, and the number of scales which significantly discriminate between intellectually handicapped and non-intellectually handicapped.
