![]() An unpublished master’s thesis (Hetz, 1994), found the CPTSDI-I to be sensitive to treatment effects in a sample of South African adolescents aged 13-17 randomly assigned to a 6-week cognitive behavioral group PTSD treatment or a comparison group. Adolescents with PTSD had significantly higher internalizing problems trauma history but no PTSD were more likely to drop out of treatment. PTSD diagnosis (as assessed by the CPTSD-I) was also associated with past-year life stressors and total trauma exposure. Similar to what is reported in the manual, they found correlations between the CPTSD-I and CBCL internalizing but not externalizing behavior problems. Trauma exposure included physical abuse/assault, sexual abuse, life-threatening illness, accident, natural disaster, and fire/explosion. Jaycox, Ebener, Damesek, & Becker (2004) examined PTSD diagnosis and its relation to treatment retention in a diverse sample of 212 adolescents in longterm residential drug treatment. They also had more comorbid diagnoses (as assessed using the Anxiety Disorder Interview Schedule for Children-Child Version) and higher scores on the When Bad Things Happen Scale. ![]() ![]() Children with PTSD were more likely to be girls, to have more extensive family alcohol and drug use, and longer experiences of maltreatment. They used the CPTSD-I to determine diagnostic status and reported significant group differences with regard to symptoms of Reexperiencing, Avoidance/Numbing, Hyperarousal, Distress, and Total Symptoms. In a diverse sample of 55 children aged 8-17 who had been physically abused or sexually maltreated, Linning and Kearney (2004) examined differences between maltreated youth with a PTSD diagnosis and those without a PTSD diagnosis. Discriminant validity is suggested by the lack of significant correlation with the CBCL externalizing scale, suggesting that the CPTSD-I is tapping a different construct. In addition there are strong correlations between the number of symptoms endorsed on the CPTSDI-I and the DICA-R and SCID PTSD (r = >.77). Both examiners diagnosed 39 participants as PTSD positive, 106 as PTSD negative, and 2 as no diagnosis, with disagreements on only 3 out of 150 cases.įrom Saigh (2004): The CPTSD-I has been found to correlate with total and subscale scores of the Revised Children’s Manifest Anxiety Scale, the Children’s Depression Inventory, the Junior Eysenck Personality Inventory Neuroticism scale, and the Child Behavior Checklist total and internalizing scales. INTERRATER RELIABILITY (Examined with Sample 1.) 2 examiners (kappa/intraclass correlation) Exposure (1/.96), Situational Reactivity (.79/.92), Reexperiencing (.86/.96), Avoidance and Numbing (.93/.96), Increased Arousal (.96/.96), Significant Distress (.96/.96), Overall diagnosis (.96/.98). INTERNAL CONSISTENCY (Cronbach’s alpha) (Examined with Sample 1 described under “Population Used to Develop Measure.”) Situational Reactivity (.58), Reexperiencing (.88), Avoidance and Numbing (.89), Increased Arousal (.80), Significant Distress (.70), Overall diagnosis (.95). ![]() Of the 42, were 6 diagnosed as PTSD positive both administrations, and 35 diagnosed as PTSD negative. TEST-RETEST RELIABILITY (Examined with Sample 2 described under “Population Used to Develop Measure.”) 2-week interval (kappa/intraclass correlation), n=42 Exposure (1/.93), Situational Reactivity (1/.94), Reexperiencing (.81/.89), Avoidance and Numbing (.86/.85), Increased Arousal (.78/.81), Significant Distress (.66/.87), Overall diagnosis (.91/.90). Statistics reported in the table are from the manual (Saigh, 2004).
