To provide information on child abuse assessment, the psychometric bas
e of the Child Abuse Potential (CAP) Inventory, a screening scale for
physical child abuse, is described. A critical review of studies repor
ting on the reliability, construct validity, and predictive (concurren
t and future) validity of the CAP Inventory physical abuse scale is pr
ovided. As part of the section on construct validity, I summarize the
physical child abuse risk factors described in the family violence lit
erature and examine the relationship between each of the risk factors
and CAP abuse scores. Incremental validity estimates, derived from stu
dies reporting predictive validity data, are reported. The utility of
using the CAP abuse scale in treatment evaluation is also discussed. T
hroughout the review, inconsistencies in study findings and gaps in th
e psychometric base for the CAP abuse scale are noted.
