The CAP Inventory is a caretaker-report measure developed to estimate the risk of a parent physically abusing a child. The test
consists of 160 questions with a total of 10 standard scales and 2 special scales (added to the measure in 1990). The 10 standard
scales include a 77-item Child Abuse Scale and 3 validity scales.
There have been multiple studies that have shown that a mother’s score on the CAP inventory is predictive of the child’s long-term intelligence, socioemotional outcome and development as well as future behavior by the parent.

The above 1-day test-retest reliabilities are for the abuse scale, control sample only.
At the 1-week test-retest: Min=.89, Max=.94, Avg=.90
At the 1-month test-retest: Min=.81, Max=.91, Avg=.83
At the 3-month test-retest: Min=.64, Max=.86, Avg=.75
Items were selected after an extensive literature search and with input from Child Protective Services. Item analysis was conducted to determine items with the greatest discriminative ability. Exploratory factor analyses and stepwise regression were used to predict abuse status. Cross-validation was used to replicate findings.

Miller, Handal, Gilner, & Cross (1991) found that Black adolescents aged 14-18 scored higher than the adult normative sample of the CAPI, suggesting that different cutoff scores need to be empirically established for adolescents. Adolescents' abuse history and history of witnessing violence were associated with higher abuse potential scores.

See Chapter 5 in the Technical Manual.
1. To avoid misclassification, cautious use of the CAPI is recommended in a situation where target base rates of physical abuse are very low.
2. Fewer false positives occur when more conservative cutoffs are used.

Initial input was gathered from researchers and CPS workers, and an initial questionnaire was developed with 334 items. An initial study was conducted with a small (n=38), fairly homogeneous group of families involved with Child Protection services in North Carolina.
Based on the results from initial validity studies, the questions were trimmed to the current 160. Based on the findings from the original study, a second study was begun. It included 130 parents who were given the 160-question form. The sample included 65 abusing parents matched with 65 nonabusing parents from North Carolina and Oklahoma.
|1. Substance abusers||Yes|
|2. Day care employees||Yes|
Pros & Cons/References
1. Easy to use and score.
2. Demonstrated ability to screen for physical abuse risk factors in parents.
3. Has been studied and validated multiple times and is used frequently.
4. Spanish version well studied.
1. According to the manual, care must be taken when utilizing this measure outside of the area of Child Protection.
2. This measure was designed as a tool to identify high-risk parents for physical abuse, and not other types of abuse.
3. It should be used only as one tool, and not as the sole predictor of abuse.
4. This measure is lengthy and takes considerable time to complete.
5. The items are face valid and many parents respond defensively. Although the validity scales help detect invalid response patterns, this still leaves the problem of having invalid responses.
