“…Higher scores indicate an increased presence of CU traits. The Portuguese validation of the ICU (Pechorro et al 2015) was used. The internal consistency for the current study, estimated by Cronbach's alpha, was: ICU total=0.90; ICU Callousness dimension = 0.88; ICU Uncaring dimension = 0.86; ICU Unemotional dimension=0.87.…”

The aim of the present study was to examine the psychometric properties of the Youth Psychopathic Traits Inventory (YPI) and of the Youth Psychopathic Traits Inventory -Short version (YPI-S) among Portuguese juvenile delinquents within a forensic sample of 221 incarcerated males (ages 13-20 years). Confirmatory Factor Analysis supported the three-factor structure of the YPI and YPI-S, and the reliability of both instruments was good for the majority of subscales and factors. The YPI and YPI-S and their subscales showed good criterion, external, and divergent validity. That is, positive associations were found with a number of external criteria including Conduct Disorder, crime seriousness, and violent crimes. Total and subscale scores on both YPI versions were positively related to the Antisocial Process Screening Device, the Inventory of Callous-Unemotional Traits, and the Child and Adolescent Taxon Scale. Finally, both the YPI and YPI-S were mostly unrelated to the Social Anxiety Scale for Adolescents. Overall, the YPI-S presented less problems with reliability, but weaker relations to external correlates. These findings justify the use of the YPI and the YPI-S among incarcerated youths.

“…Internal consistency based on Cronbach's alpha has previously been reported as .70 for Callousness, .64 for Unemotional, .73 for Uncaring, and .77 for the ICU total (Essau et al 2006). The Portuguese version of the ICU was used (Pechorro et al 2016c). The internal consistency of the ICU total for the current study estimated by Cronbach's alpha was .88.…”

The Barratt Impulsiveness Scale-11 Among a School Sample of Portuguese Male and Female Adolescents

Few personality traits are as socially relevant as impulsivity, but few self-report measures have been specifically developed for adolescents and children. The aim of the present study was to examine the psychometric properties of the Barratt Impulsiveness Scale version 11 (BIS-11) among a mixed-gender sample of 782 Portuguese youth (M = 15.87 years; SD = 1.72), in a school context. Confirmatory factor analysis revealed the expected 6-factor first-order structure, but the 3-factor second-order factorial structure did not present a good fit. Cross-gender measurement invariance was demonstrated only in terms of weak invariance. Nonetheless, the Portuguese adaptation of the BIS-11 demonstrated some generally acceptable psychometric properties of internal consistency, mean interitem correlation, convergent validity, discriminant validity, and criterion-related validity of statistically significant associations with conduct disorder symptoms, alcohol abuse, drug use, and unprotected sex. The use of the BIS-11 among the male and female youth population is psychometrically justified, and it can be a useful measure to identify impulsive adolescents who are at considerable risk of personal injury and present a potential source of injury to others.

“…The ICU was developed from items within the APSD (Frick and Hare 2001) and expanded to provide a more complete assessment of CU traits in children (Fanti et al 2009). Although the specific factor structure of the ICU has been variously reported, the majority of studies find three subscales of the ICU (i.e., `uncaring,' `unemotional,' and `callousness') (e.g., Fanti et al 2009; Roose et al 2010; Ezpeleta et al 2013; Pechorro et al 2016). The youth self-report version of the ICU has demonstrated good test-retest reliability (Feilhauer et al 2012), however the reliability of the teacher- and parent-report versions have yet to be tested.…”

The Inventory of Callous-Unemotional Traits (ICU) in Children: Reliability and Heritability

et al. 2016

View full text Add to dashboard Cite

Callous-unemotional (CU) traits comprise the core symptoms of psychopathy, yet no study has estimated the heritability of CU traits in a community sample of children using an instrument designed solely to assess CU traits. The current study uses data from 339 twin pairs aged 9-14 to examine the reliability and heritability of the parent-report Inventory of Callous-Unemotional Traits (ICU) at two assessments approximately 3 weeks apart. Time-specific measurement error was taken into account to obtain a more accurate estimate of the heritability reflecting the latent liability to CU traits. Test-retest reliability was .84 and heritability at visit 1 was 39%. The heritability of the latent liability to CU traits was 47%. This latent liability contributed 79% of the variance in ICU score at visit 1 and visit 2. This is the first study to account for measurement error while examining the heritability of CU traits, furthering our understanding of psychopathy in children.
