Measure Description:

The PT-SIC is a self-report measure of PTSD symptoms for
children aged 4-8. It assesses the DSM-IV criteria for the
diagnosis of PTSD. The language is simple, to allow young
children to respond to the questions in an interview format. The
measure includes several validity questions to ensure that the
child understands how to respond and endorses everyday
complaints.

Sample Item(s):

Domains	Scale	Sample Items
PTSD-Related Symptomatology (child)	Criteria A: Trauma Exposure	Do you ever hear gun shots around your neighborhood? Did you ever see a car crash or a big fire?
	Criteria B: Reexperiencing	Some children think about really bad things that happened to them. Do you think about really bad things that happened to you? Do you think about these bad things a whole lot like everyday or just sometimes?
	Criteria C : Avoidance	Some children can’t remember bad or scary things. Is it sometimes hard for you to remember bad or scary things?
	Criteria D : Hyperarousal	Some children can’t fall asleep because they are thinking about bad or scary things that happened. Is it ever hard for you to sleep because you’re thinking about really bad or scary things?

Score 2+ on a symptom indicates child meets criteria for symptom. DSM-IV PTSD diagnosed by totaling symptoms in each category (B,C,D) and determining if required number of symptoms in each category are met for PTSD diagnosis.

References for Content Validity:

A working group of clinicians and graduate students assessed an initial pool of 130 items
that were designed to assess the 17 criteria for PTSD. Following their review a pool of 101
items remained. Fourteen clinicians (seven licensed psychologists and seven advanced
graduate students) who specialized in working with traumatized children were asked to rate
how well each item fit the symptom criteria it was matched to on a 1-4 scale (4=excellent,
3=good fit, 2=average fit, 1=poor fit). Items with an average score of 2.7 or higher were the
only ones retained.

The instrument with 81 items was then administered to 70 maltreated children. Afterward, 51
questions were dropped from the measure due to children's inability to understand and
reliably answer each question. The remaining 30 items were sent out to several
internationally recognized experts on trauma for commentary. Wording revisions were made
to these 30 items based on this feedback, resulting in the final 30 items. Consistent with
DSM-IV criteria for PTSD.

Construct Validity:

Validity Type	Not known	Clinical Samples	Diverse Samples
Convergent/Concurrent		Yes	Yes
Discriminant	Yes
Sensitive to Change	Yes
Intervention Effects	Yes
Longitudinal/Maturation Effects	Yes
Sensitive to Theoretically Distinct Groups	Yes
Factorial Validity		Yes

References for Construct Validity:

TSCC (r=.66), Child Dissociate Checklist and the Children's Perceptual
Alteration Scale (r=.38).

Also measure does show evidence of factorial validity. It has two main factors:
Reexperiencing (alpha=.74) and Fear and Hyperarousal (alpha=70).

Criterion Validity:

	Not Known	Not Found	Nonclinical Samples	Clinical Samples	Diverse Samples
Predictive Validity:	Yes
Postdictive Validity:				Yes

Sensitivity Rate Score:

0.14

Overall Psychometric Limitations:

Psychometrics were collected using a sample of children aged 4-17. It is unclear how many
young children (aged 4-8) were sampled. Since the measure was developed specifically for
the young age range, more data and psychometric information is need with this age group.

Population Information

Population Used For Measure Development:

1. 70 Maltreated children were interviewed in the item selection phase of measure
development. No ethnicity, SES, region/location/city, education level, or age range of
these children were provided. Abuse was physical or sexual abuse, having their life
threatened, hearing gunshots, or being in a serious accident.

2. 400 children aged 4-17 were screened. 220 children aged 4-17 were interviewed using
the PT-SIC as part of an assessment for allegations of abuse and neglect. These 220
endorsed a potentially traumatic event and were administered the full PT-SIC. Children
were from Mt. Sinai Hospital's Under the Rainbow Program in Chicago, Illinois. No
ethnicity, SES, or education level for these children was provided.

Pros & Cons/References

Pros:

1. One of the few measures developed to directly interview young children about PTSD symptoms.

Cons:

1. Some of the language still appears somewhat complex for young children.
2. There are limited psychometric data available.
3. Not widely used or shown valid among different cultures. No translations available.
