The 38-item Child Sexual Behavior Inventory (CSBI) was developed to assess children who have been sexually abused or are suspected of having been sexually abused. The measure is designed to be completed by a female caregiver. It is one of the most widely used measures of sexual behaviors. It yields a total CSBI score, a Developmentally Related Sexual Behavior Score, and a Sexual Abuse Specific Items Score, with norms by age and gender for these scales. It also yields scores on 9 domains: 1) Boundary Problems, 2) Exhibitionism, 3) Gender Role Behavior, 4) Self- Stimulation, 5) Sexual Anxiety, 6) Sexual Interest, 7) Sexual Intrusiveness, 8) Sexual Knowledge, and 9) Voyeuristic Behavior. The CSBI is a revision of the CSBI-R and CSBI-1. It contains 22 of the items from the previous version, with the remaining items reworded for greater readability (Friedrich et al., 2001).

Global Rating: 
Somewhat established, psychometrics validated by researchers other than the authors
Separate age groups Clinical populations Separate for Men And Women
Psychometric Norm Notes: 
Friedrich (1997) 1. Normative data for the CSBI represent 1,114 children, combined from three nonclinical samples: (a) 723 children who were in the waiting area of a Community Pediatrics Clinic in Rochester, Minnesota; (b) 111 children who were in the waiting area of a Community Family Medicine Clinic in Rochester, Minnesota; and (c) 280 children from the Los Angeles, California, area, the majority of whom were lower income and of minority status." The total sample included the following: 49.7% female, 51.3% males; 77.7% Caucasian, 7.7% African-American, and 11.6 % Latino. Norms are presented in the manual's appendix by gender and age group (2-5 years, 6-9 years, 10-12 years). There are no norms for fathers. 2. Data were also collected in multiple sites in the U.S. and Canada on 512 children with a documented history of sexual abuse. The average time since abuse was 10.9 months (SD=13.9), the average length of abuse was 9.3 months (SD=12.3 months). Children were aged 2-12 (M=7.44; SD=2.63); 62.7% female, 37.3% male; 76% White, 6.9% African American, 8.7% Hispanic, 2.2% Asian, 2.4% Native American, 3.8% Other; 62.4% of families had annual incomes below $25,000.
Clinical Cutoffs: 
T>65 is the cutoff for clinically signficant problems

Pros & Cons

1. Sexual behaviors are important to assess, and this measure appears useful in capturing different dimensions of sexual behaviors. 2. This is one of the most widely used and well-researched tests tapping the domain of child sexual behaviors. The Trauma Symptom Checklist for Children also assesses for sexual behavior, but does so using self-report. 3. Wording of items: items appear to be clear. Rating scale is an improvement over previous rating scales with sexual behavior items (e.g., CBCL). 4. Psychometrics have been evaluated by age and gender. 5. Measure has been demonstrated to show change with treatment.
1. The item uses a 6-month timeframe. This timeframe is not appropriate for treatment outcome studies of shorter or similar duration. The timeframe would add error if it is adhered to and informants are responsive to it. Although the timeframe can be adjusted, the norms were gathered using that time period and would not necessarily apply with a new timeframe. 2. The measure is face valid and there are no validity scales. There were validity items used during the normative studies, but they were dropped from the current version. The manual advises users to determine, during follow-up interviews, whether caregivers read and interpreted items appropriately. 3. Although psychometrics have been examined in studies involving lower-socioeconomic-status individuals, the majority of studies have been conducted with Whites. More studies are needed with diverse populations. 4. The measure was designed to be completed by female caregivers. Although the test-retest reliability between mothers and fathers from intact homes is good, more research is needed regarding reports from fathers if fathers' reports are to be used. 5. While the measure has been translated in multiple languages, translations and studies that involved them were generally conducted with earlier versions of the CSBI. 6. THIS IS A CAUTION RATHER THAN A CON: While the measure has been found to be valid and useful, the authors and others point out that many sexually abused children display low levels of sexual behavior problems, and many children who were not sexually abused exhibit high levels of sexual behavior problems.

Author Comments: 
The author provided feedback, which was integrated. The publishers commented that although this measure represents a revision of early versions of the CSBI, it is published under the title "Child Sexual Behavior Inventory (CSBI)."
