In the ‘Een Goed begin’ longitudinal study, aggressive traits of 152 infants (85 of them boys) were assessed using the CICS. In this study, reliability and validity of the instrument were examined. Internal consistency was .44 for children aged 6 months, and .54 for children around 12 months old. For children aged 12 months old in the low-risk part of our sample however, this number increased to .68. Test-retest reliability between these two time points was .20. In validity analysis, a correlation was expected between CICs ratings and infant temperament as well as physical aggression. At 6 months old the CICS correlated with several aspects of infant temperament (r = -.32, -.24, .37, p <.01) while at 12 months old there were no correlations between the CICS and infant temperament. At 12 months of age, a correlation was found with physical aggression scores (r = .34, p >.01) . Since reliability and validity were not found to be sufficient, caution must be exercised when using the CICS as a measure of infant aggression in research and practice.Show less
