Previous research has produced mixed findings on the role of child and family factors in the genesis of childhood cruelty. The authors examined the relationships of cruelty to animals to a range of child and family factors. First, the authors test the idea that cruelty is a callous aggression that will be more strongly associated with psychopathic (callous or unemotional, CU) traits than general externalizing problems. Second, the authors operationalize family problems as open conflict rather than parenting problems as used earlier. Results indicated that for both genders, CU traits were associated strongly with cruelty. For boys, externalizing problems also added prediction in regression analyses. Family conflict was not associated with cruelty for either. These results suggest that cruelty to animals may be an early manifestation of the subgroup of children developing conduct problems associated with traits of low empathy and callous disregard rather than the more common pathway of externalizing problems and parenting problems.

Cruelty to animals may be a particularly pernicious aspect of problematic child development. Progress in understanding the development of the problem is limited due to the complex nature of cruelty as a construct, and limitations with current assessment measures. The Children and Animals Inventory (CAI) was developed as a brief self- and parent-report measure of F. R. Ascione's (1993) 9 parameters of cruelty. The CAI emerged as a reliable, stable, and readily utilized measure of cruelty using parent and child reports. Children (especially the older children) reported higher rates of cruelty than their parents and boys reported more cruelty than girls. Self- and parent-reports showed good convergence with independent observations of cruelty versus nurturance during free interactions with domestic animals. The results indicate that cruelty to animals can be reliably measured using brief child and parent report measures.
