897 students from Technical, Graduates and undergraduate courses completed the translated BIS-11.

Translation Method
English to Brazilian Portuguese BIS-11 translation was developed by six translators bilingual in English and Brazilian Portuguese. Back translation was made by an American English teacher. Then, the three versions (original, translated and back-translated) were compared by a committee and final consensus was reached the final translated version of BIS-11.

Item Analysis
Cronbach’s alpha = .80
Test-retest reliability (7-month)  r = .72, p < .001

Internal Structure using Content, Exploratory and Confirmatory Factorial Analysis
Evidences based on content items analysis and factorial analysis diverged from the original proposed by Patton, Stanford, Barratt (1995) three factor loadings. This study found two latent factors labeled: (1) inhibitory control, and 2) nonplanning impulsiveness.

External Validity 
Brazilian BIS-11 version showed correlation with Hyperactivity and Attention symptoms assessed by Adult Self Report Scale (ASRS-18), cigarette Smoking and alcohol abuse.

    Raramente / Nunca = 1 
    De vez em quando = 2 
    Com frequência = 3 
    Quase sempre/Sempre = 4

BIS-11 Controle inibitório = Somatório itens (2, 3, 5, 6, 8*, 9*, 11, 14, 16, 17, 18, 19, 20*, 21, 22, 23, 24, 25, 26, 28)
BIS-11 Falta de planejamento = Somatório itens (1, 4, 7*, 10*, 12*, 13*, 27, 30*)
Escore total = Somatório das respostas a todos os itens

    - Os itens assinalados com um asterisco (*) recebem escore inverso para o cálculo dos escores parciais e total (4,3,2,1). 
    - Os itens 15 e 29 não compõem os escores parciais. No entanto, para mantar o escore final comparável com os estudos internacionais, os itens 15 e 29 são incluídos no cálculo do escore total

Normative Data 2015
A 2015 publication reported normative data from 3,053 adults recruited from the community, across 8 Brazilian states. All subjects were recruited from schools, universities, leisure centers, and workplaces. Exclusion criteria were age under 18 years, illiteracy, and self-reported neurological or psychiatric disorders. This study used Brazilian Portuguese version the form developed by from Malloy-Dinez et al 2010 (described above). Normative mean for Total score was: 61.92, standard deviation was 10.29, and internal consistency was .790 (Cronbach’s alpha)

Translation Method
The European Portuguese version of the BIS-11 was adapted from the Brazilian Portuguese version of the BIS-11 (see Malloy-Dinez et al., 2010). An initial translation was conducted by Ana Rita Cruz along with two forensic psychologists. Based on this first revision, a pilot study was conducted with debriefing interview about the clarity of items and face validity of the scale. Following this pilot work, a second revision was constructed in a consensus meeting, which was then back translated to English by an independent bilingual translator.

Adolescent European Portuguese Version

Translation Method
The European Portuguese version

221 boys (ages 13-20) incarcerated in the Portuguese Ministry of Justice.

Translation Method
English to European Portuguese conducted by authors Pechorro and Gonçalves. Some items adapted for clarity and to make them consistent with situations commonly encountered by adolescents. Back translation was conducted by "a native English speaker with considerable professional experience in translating psychology-related scientific texts". Forward and back translated versions compared and revised to resolve any non-equivalence in meaning.

Item Analysis
Cronbach’s alpha = .84

Convergent and Divergent Validity
Moderate correlations were noted between BIS-11 total and 1st order factors with scales from the Antisocial Process Screening Device-Self-Report, Youth Psychopathic Traits Inventory, Child and Adolescent Taxon Scale, and Reactive–Proactive Aggression Questionnaire supporting interpretation of convergent validity. Divergent validity was supported by lack of association of BIS-11 scales with Social Anxiety Scale for Adolescents.

Construct Validity
Significant correlations were found between the translated BIS-11 total score with younger age of crime onset, number of Conduct Disorder symptoms, Conduct Disorder diagnosis (binary), severity of criminal acts, and alcohol and drug use.
