Methods  As part of a study of in utero exposure to cocaine, children completed the Levonn interview for assessing children's symptoms of distress in response to witnessing violence. The children's caregivers completed the Exposure to Violence Interview (EVI), a caretaker-report measure of the child's exposure to violent events during the last 12 months. The EVI was analyzed as a 3-level variable: no exposure, low exposure, and high exposure. The caregivers also completed the Children's Behavior Checklist (CBCL).

Results  Of 94 six-year-old children, 58% had no exposure to violence, 36% had low exposure to violence, and 6% had high exposure to violence, according to caretaker reports. The children's median±SD Levonn score was 64 (SD ± 19.3). The mean SD ± CBCL total T-score was 53 (SD ± 10.2). In multiple regression analyses with gender, low and high exposure on EVI, Levonn, and prenatal cocaine exposure status as predictors, the Levonn score explained 4.8% of total variance in children's CBCL internalizing scores, 9.1% of the total variance in CBCL externalizing score, and 12.2% of the total variance in CBCL total score (P = .04, P = .004, and P<.001, respectively).

Conclusions  After accounting for the caretaker's report of the level of the child's exposure to violence, the child's own report significantly increased the amount of variance in predicting child behavior problems with the CBCL. These findings indicate that clinicians and researchers should elicit children's own accounts of exposure to violence in addition to the caretakers' when attempting to understand children's behavior.

The objective of this study was to address 2 questions raised in prior work. First, how much distress do young children report relative to violence that they may have witnessed; and second, to what extent are the children's responses associated with parents' reports of children's behavior?

PARTICIPANTS AND METHODS

When their children were 6 years old, primary caregivers were interviewed by trained examiners using the Achenbach Child Behavior Checklist (CBCL), a measure of caretaker reports of child behavior. The CBCL yields age- and gender-normed T-scores for children's internalizing, externalizing, and total behavior problems. T-scores greater than 70 are considered the clinical cutoff for referral. At the same visit, the Exposure to Violence Interview (EVI) was also administered to the caregiver. The EVI is a research tool developed at our site and used throughout the past 10 years in this study to measure an individual's exposure to violence during the prior 12 months. The EVI covers 6 types of violent events: yelling, kicking and punching, attacking with a weapon, threatening with a weapon, rape, and knifing. The caregiver reports whether the child witnessed the event in the last 12 months (range, 0-6 months) and how many times. Prior to administering the EVI, the caregivers are instructed to respond to the questions regarding what the child may have seen or heard on the street, at home, or in school; but not on TV, on the news, or in the movies. This item has been administered to caregivers approximately every year for their child's entire lifetime, with the same instructions to exclude media violence. The EVI was analyzed as a 3-level variable: (1) no exposure, or yelling only; (2) low exposure (the most violent event witnessed was kicking or punching); (3) high exposure (witnessed threatening with a weapon, knifing, attacking with a weapon, or rape). At the same visit, other examiners who were blinded to the child's prenatal history of drug exposure and to caregivers' reports, independently interviewed the 6-year-old children using the Levonn, which assesses children's distress symptoms over witnessed violence.⁵ Created by Richters, Valla, and Martinez at the National Institute of Mental Health (Bethesda, Md) in 1990, the Levonn assesses similarities between the child's experience with that of a cartoon character named Levonn, and includes a 2 to 3 sentence script that the interviewer reads at each cartoon ("Here is Levonn feeling very sad for a whole day. He gets up in the morning feeling sad, he feels sad all day, and he still feels sad at bedtime. How many times have you felt like Levonn?"). The format for indicating frequency consists of thermometers filled with varying degrees of mercury that are coded as 1 to 3 (never, some of the time, a lot of the time) yielding a possible range of 39 to 117. Test-retest reliability for a composite score of distress ratings was 0.81 for a random subsample of 22 first- and second-graders in Washington, DC, with a significant relation to parent CBCL scores (r₇₆ = 0.30) and to parent rating of child distress based on the CCDS (r₇₆ = 0.32).

Linear regression was used to determine the relationship between Levonn and CBCL, controlling for gender, cocaine level, and EVI score. The variables of gender, cocaine level, and EVI were chosen a priori based on clinical experience and the primary purpose of the research study (cocaine exposure in utero). The assumption of linearity was verified through examining scatterplots and residual plots. The bivariate analyses were done using 2-sample 2-sided t tests for gender and EVI, and analysis of variance for cocaine level. The analysis of correlation was done using a 2-sided t test for a correlation coefficient equal to zero. The contribution to the r² coefficient was calculated using type III sums of squares to determine the partial r² as a result of the Levonn. The plan of analyzing the EVI as a 2-category construct of low and high violence exposure was decided based on examination of the distribution of the data.

RESULTS

The CBCL scores in this cohort showed slightly higher numbers in the borderline and clinical range than would be expected in the normal population (Table 1). The mean ± SD CBCL total T-score was 53 ± 10.2. The children's median Levonn score was 64. The 25th percentile Levonn scores in this sample was 46, and the 75th percentile score was 79.

As a first analysis, bivariate associations were done to examine the outcome (CBCL score) as it relates to the following variables: gender (shown in other studies to influence behavior problems when children witness violence), cocaine exposure, and parental report of high or low violence exposure. A regression model (Table 2) showed that after controlling for gender, low and high parental report of witnessed violence (EVI), and prenatal cocaine exposure, the Levonn score contributed significantly to the total variance in CBCL internalizing, externalizing, and total behavior problem scores with gender, cocaine exposure, and EVI score, with each contributing less than 10%. There were 4 children whose parents did not complete the EVI who were excluded from this analysis.

COMMENT

Since only 2 other studies have published results of the Levonn in a clinical cohort,^{4, 10} and both have analyzed the results differently, it is difficult to compare the scores obtained by our cohort with those of other studies. We would argue that a median score of 64, which would mean that participants endorsed at least "some of the time" on more than half the items, reflects clinically meaningful distress. Regardless of the magnitude of distress reported relative to that found in other cohorts, it is impressive that this distress explained a significant variance in caregivers' reports of child behavior.

Limitations of this study include a relatively small sample of children and parents, all of whom reside in high risk urban areas. The Levonn has been criticized as a poor means by which to extrapolate child exposure to violence since it does not specifically ask if the child has witnessed the event, but whether or not they are experiencing distress in response to violent events. Thus, in future studies, it will be necessary to replicate the current findings using a more direct measure of child report of exposure such as the Violence Exposure Interview.

In conclusion, while these findings need to be replicated in larger and more diverse samples, they suggest that it is important for both researchers and clinicians to not only interview caregivers, but also to directly elicit children's own accounts of exposure to violence and their feelings about such exposure in understanding the etiology and correlates of children's behavior.

What This Study Adds The existing knowledge is that in preadolescent and adolescent children, witnessing significant violence has behavioral effects. In our study sample of 6-year-old inner-city children, both parents and children reported high exposure to violence and distress. After accounting for the caretaker's report of the level of the child's exposure to violence, the child's own report significantly increased the amount of variance in behavior problems predicted. Children as young as 6 years should be asked directly about their experience of witnessing violence.
