- Psychometric Properties of a Short Version of the Barratt Impulsiveness Scale-11 among a School Sample of Portuguese AdolescentsPublication . Pechorro, Pedro; Oliveira, João Pedro; Gonçalves, Rui Abrunhosa; Jesus, Saul Neves deThe main aim of the present study was to examine the psychometric properties of a 18-items short version of the Barratt Impulsiveness Scale - 11 short among a Portuguese school sample (N =543) of male and female adolescents. The BIS-11 short version demonstrated good psychometric properties, namely in terms of its three-factor structure, internal consistency, convergent validity, and discriminant validity. In terms of criterion-related validity positive correlations were found with Conduct Disorder symptoms, alcohol use, cannabis use, and unprotected sex (i.e., sex without using condoms). The psychometric properties of the BIS-11 short version generally justify its use among Portuguese adolescents.
- Psychometric properties of the socially desirable response Set-5 among incarcerated male and female juvenile offendersPublication . Pechorro, Pedro; Ayala-Nunes, Lara; Oliveira, João Pedro; Nunes, Cristina; Gonçalves, Rui AbrunhosaThe main aim of the present study was to examine the psychometric properties of the Socially Desirable Response Set-5 (SDRS-5) among a forensic sample (N = 324) of incarcerated male (n = 221) and female (n = 103) juvenile offenders. The Portuguese validation of the SDRS-5 demonstrated good psychometric properties, namely in terms of its factor structure, internal consistency, convergent validity, and discriminant validity that overall justifies its use among this population. Findings are discussed in terms of the use of the SDRS-5 with male and female juvenile offenders. (C) 2016 Elsevier Ltd. All rights reserved.
