Although there are international data on the prevalence of behavioral problems through childhood/adolescence, there is still a need to explore emotional/behavioral problems experienced by Brazilian adolescents, especially in situations of extreme social problems or social vulnerability (SV). This is an observational, cross-sectional study, carried out with a convenience sample, to describe emotional/behavioral problems of adolescents living in a high SV scenario in the city of Salvador-BA, from their parents or guardians’ point of view. Sociodemographic questionnaire and CBCL/6-18 were applied to a sample of 274 adolescents’ parents/guardians. Data analysis found that 20.4% of the sample had problems in the clinical range for CBCL’s Total Problems. Sociodemographic variables can impact behavioral problems in adolescence and need to be investigated. This study adds new data on child and youth psychopathologies at the national level and can promote preventive actions and referrals aimed at this population.

Introduction The Cognitive Distortions Questionnaire (CD-Quest) is an instrument that identifies logical errors or cognitive distortions and is used in trial-based cognitive therapy (TBCT). However, it had previously only been available for adults. Objectives To develop and validate a version of the CD-Quest for teens (CD-Quest-T) aged 11 to 17 years and test its psychometric properties. Method A total of 299 schoolchildren participated in the investigation. After content validity was assessed, the language was adapted for the target age group, and the length of the instrument was reduced to eight items (from the initial 15). Five cognitive therapists analyzed the content and structure of the items. Finally, to investigate the construct validity of the CD-Quest-T, the instrument was divided into a full scale and two subscales, which measure the frequency of the distortions and the intensity attributed to them, respectively. Results The overall internal consistency of the scale was α = 0.77, whereas subscale indices were α = 0.75 for the frequency scale and α = 0.73 for the intensity scale. Results from exploratory factor analysis and concurrent validity analysis indicated that the CD-Quest-T items have good psychometric properties and generate scores reliably. Conclusion The psychometric properties of the CD-Quest-T demonstrate its adequacy for measurement of cognitive distortions in adolescents.
