Behavior Screen for Siblings


The Behavior Screen for Siblings is a 24-item instrument developed by the Fast Track Project. It was administered to the next youngest sibling of each study child when she/he had completed kindergarten and had been in the care of the primary caregiver for at least two years. The parent is asked to evaluate the occurrence of behavior problems on a 4-point scale (Never, Almost Never, Sometimes and Often).

Exploratory factor analyses were conducted utilizing the normative sample for year 6 (cohort 1). One factor was extracted explaining 38% of the total variance. With this solution, all items on the questionnaire had salient factor loadings (ls); "Cruel to Animals" had the lowest loading (.31). Examination of the 2-factor solution showed that almost all the items loaded on the first factor, with the exception of 4 items which double loaded on both factors. A total score was computed as the mean of all the items.

This scale has good internal consistency as shown by the Cronbach alpha correlation coefficient. It is recommended that the normally-distributed total scale score be utilized in analyses. In a 4(Site) X 3(Cohort) between-subject analysis of variance (fixed factors), the Site X Cohort interaction effect was non-significant.
