Parallel/Alternate Forms

Parallel Form: 
No
Alternate Form: 
Yes
Different Age Forms: 
Yes
Altered Version Forms: 
Yes
Describe Alternative Forms: 

1. One version for girls and one for boys. They differ in that the cartoon characters depicted are either male or female.

2. VEX-Preschool Version, used by Shahinfar, Fox, & Leavitt (2000), has fewer items and is for younger children.

3. VEX-R Parent Report: briefly described in Shahinfar et al. (2000).

The VEX-R was modified for use with an Israeli population of children. The name of the cartoon character was changed and several of the items were altered. See Raviv, Raviv, Shimoni, Fox, & Leavitt (1999); Raviv, Erel, Fox, Leavitt, Raviv, Dar, et al. (2001).

Internal ConsistencyCronbach's alpha0.720.86
References for Reliability: 

There are no interrater statistics in terms of interviewers. The Shahinfar et al. (2000) study compares parents' and children's reports of their children's exposure to violence.

So it is comparing the VEX-R with the VEX-R Parent Report and found no significant relationship between Parent and Child reports of exposure to violence.

Content Validity Evaluated: 
Yes
References for Content Validity: 

The measure is face valid and asks about similar areas of community violence exposure as other measures of this sort. It was developed based on the Richters & Martinez (1990) measure: "Things I Have Seen and Heard: An Interview for Young Children About Exposure to Violence."

References for Construct Validity: 

Children who were found to have experienced exposure to violence on the VEXR were found to have higher internalizing and externalizing symptoms on the CBCL and higher child-reported distress symptoms (Shahinfar et al., 2000). Stein, Zima, Elliott, Burnam, Shahinfar, Fox, & Leavitt (2001) also reported, in their diverse sample of 2,103 foster care children, that being a witness to violence based on the VEX-R did not vary by age, gender, or ethnicity. Violence victimization was associated with higher trauma and depression symptoms with children who witnessed more severe violence (e.g., weapon- or assault-based violence), reporting more PTSD and depression symptoms (assessed by the Children’s Depression Inventory and Levonn: A Cartoon-Based Interview for Assessing Children's Distress Symptoms).

Predictive Validity:Yes
Postdictive Validity: Yes
Overall Psychometric Limitations: 

1. Limited psychometric data available.
2. Shahinfar et al. (2000) found poor concordance between VEX-R Parent and Child reports. However, this may be due to differences in parents’ and children's understanding of the items or parents' knowledge of their children's exposure.

Population Information

Population Used For Measure Development: 

Sample: 40 Caucasian primarily suburban preschool aged children.

Measure was then used in a study by Shahinfar et al. (2000) with 155 African American children: 79 boys and 76 girls, aged 3½-5 from low SES families living in a community just outside Washington DC.

The average family income was less than $7,200, and almost 50% of the sample was entirely supported by public assistance.

Pros & Cons/References

Pros: 

1. This is the only self-report measure of trauma exposure for young children with a parallel Parent Report form.

Cons: 

1. Caution should be used when administering the measure to preschool-aged children because some young children may not have the cognitive maturity to truly understand the items. The authors recommend using probe questions, in addition to the measure, to ensure that children understand that they are being asked about “true life events” rather than violence witnessed on television or in the movies.
2. Very limited psychometric data.

Author Comments : 

The authors reviewed this review and provided feedback, which was incorporated. They indicated that the Spanish version is available from the authors, and the VEX-R has been used with both group and individual administration. The authors also commented that clinicians have used the instrument to foster discussion with young children about events that they have experienced.
