Cross-cultural adaptation, validity, and reliability of the Child and Adolescent Behavior Inventory (CABI) for use in Brazil

Abstract Objective The Child and Adolescent Behavior Inventory (CABI) is a cost-free 75 question-questionnaire developed by an Italian group to collect information from parents on the behavior of children and adolescents aged 6 to 18 years. It assesses different areas of children's behavior and psychopathology, including internalizing and externalizing symptoms, and can be used to identify children at risk of mental disorders both in clinical and epidemiological settings. In this study, the authors present a Brazilian-Portuguese adaptation of the CABI and its psychometric properties. Methods First, the authors conducted a rigorous transcultural adaptation of CABI's questions and instructions for the Brazilian context. In an online sample of 598 parents, the authors found high reliability (internal consistency) for the CABI's main subscales. Results Validity was supported by exploratory factor analysis (the authors found 6 factors representing several aspects of psychopathology both according to the DSM and HiTop models) and significant differences in most CABI's subscales between children with parent-reported psychopathology and typically developing ones. The present study suggests that the adapted version of CABI is a valid and reliable measure that can be used in Brazil. Conclusions The CABI can be useful to the pediatrician to get fast but wide information from parents on the behavioral condition of their children or adolescents, and also to decide whether it is appropriate to consult a mental health professional.

Parent SNAP-IV rating of attention-deficit/hyperactivity disorder: accuracy in a clinical sample of ADHD, validity, and reliability in a Brazilian sample, / Avaliação do instrumento SNAP-IV pelos pais no transtorno de déficit de atenção/hiperatividade: acurácia em uma amostra clínica de TDAH, validade e confiabilidade em uma amostra brasileira,

ABSTRACT Objective: To investigate the psychometric properties of the short or multimodal treatment study version of the Swanson, Nolan, and Pelham, Version IV (SNAP-IV) scale, which measures attention-deficit/hyperactivity disorder and oppositional defiant disorder symptoms. Methods: Participants were 765 parents of children from 4 to 16 years old (641 non-attention-deficit/hyperactivity disorder and 124 attention-deficit/hyperactivity disorder children) from Belo Horizonte, Brazil, who reported sociodemographic characteristics and answered the SNAP-IV. Parents of the clinical sample also underwent the K-SADS-PL interview. Results: Age was significantly associated with SNAP-IV hyperactivity-impulsivity problems (r = −0.14), but not with inattention or oppositional defiant disorder. Sex was a significant influence on attention-deficit/hyperactivity disorder and oppositional defiant disorder severity (all p < 0.001), with boys showing higher scores in the full sample, but not within the attention-deficit/hyperactivity disorder group. Exploratory and confirmatory factor analysis supports a three-factor structure of the SNAP-IV scale. Moderate-to-strong correlations were found between SNAP-IV and K-SADS-PL measures. All SNAP-IV scales showed very high internal consistency coefficients (all above 0.91). SNAP-IV inattention scores were the most predictive of attention-deficit/hyperactivity disorder diagnosis (AUC: 0.877 for the averaging rating method and the raw sum method, and 0.874 for the symptom presence/absence method). Conclusion: The parent SNAP-IV showed good psychometric properties in a Brazilian school and clinical sample.

RESUMO Objetivo: Investigar as propriedades psicométricas da versão curta ou MTA da escala Swanson, Nolan e Pelham, versão IV (SNAP-IV), que mede os sintomas do transtorno de déficit de atenção/hiperatividade e transtorno desafiador de oposição. Métodos: Os participantes incluíram 765 pais de crianças de 4 a 16 anos (641 crianças sem transtorno de déficit de atenção/hiperatividade e 124 com transtorno de déficit de atenção/hiperatividade) de Belo Horizonte, Brasil, que relataram características sociodemográficas e responderam o SNAP-IV. Os pais da amostra clínica também foram submetidos à entrevista com K-SADS-PL. Resultados: A idade foi significativamente associada aos problemas de hiperatividade-impulsividade no SNAP-IV (r = −0,14), mas não à desatenção ou aos transtornos desafiadores de oposição. O sexo foi uma influência significativa na gravidade do transtorno de déficit de atenção/hiperatividade e transtorno desafiador de oposição (todos os p < 0,001), os meninos apresentaram escores mais altos na amostra completa, mas não no grupo de transtorno de déficit de atenção/hiperatividade. A análise fatorial exploratória e confirmatória apoia uma estrutura de três fatores da escala SNAP-IV. Foram encontradas correlações moderadas a fortes entre as medidas dos instrumentos SNAP-IV e K-SADS-PL. Todas as escalas do SNAP-IV mostraram coeficientes de consistência interna muito altos (todos acima de 0,91). Os escores de desatenção do SNAP-IV foram os mais preditivos do diagnóstico de transtorno de déficit de atenção/hiperatividade (AUC - área sob a curva ROC: 0,877 para o método de classificação da média e o método da soma bruta e 0,874 para o método de presença ou ausência de sintomas). Conclusão: A avaliação do SNAP-IV pelos pais apresentou boas propriedades psicométricas em uma escola brasileira e amostra clínica.

Cross-cultural adaptation, validity, and reliability of the Parenting Styles and Dimensions Questionnaire - Short Version (PSDQ) for use in Brazil

Objective: The Parenting Styles and Dimensions Questionnaire (PSDQ) is used worldwide to assess three styles (authoritative, authoritarian, and permissive) and seven dimensions of parenting. In this study, we adapted the short version of the PSDQ for use in Brazil and investigated its validity and reliability. Methods: Participants were 451 mothers of children aged 3 to 18 years, though sample size varied with analyses. The translation and adaptation of the PSDQ followed a rigorous methodological approach. Then, we investigated the content, criterion, and construct validity of the adapted instrument. Results: The scale content validity index (S-CVI) was considered adequate (0.97). There was evidence of internal validity, with the PSDQ dimensions showing strong correlations with their higher-order parenting styles. Confirmatory factor analysis endorsed the three-factor, second-order solution (i.e., three styles consisting of seven dimensions). The PSDQ showed convergent validity with the validated Brazilian version of the Parenting Styles Inventory (Inventário de Estilos Parentais - IEP), as well as external validity, as it was associated with several instruments measuring sociodemographic and behavioral/emotional-problem variables. Conclusion: The PSDQ is an effective and reliable psychometric instrument to assess childrearing strategies according to Baumrind's model of parenting styles.

Brazilian version of the Cognitive Failures Questionnaire (CFQ): cross-cultural adaptation and evidence of validity and reliability

Objective: Cognitive failures are simple mistakes in routine activities, such as forgetting commitments and experiencing difficulty concentrating. The Cognitive Failures Questionnaire (CFQ) was designed to assess the frequency of these errors in everyday life. Although widely used in psychiatry and psychology, both in clinical and research settings, it has not been adapted for use in Brazil. Our objective was to perform cross-cultural adaptation of the CFQ for the Brazilian reality and assess its validity and reliability. Methods: The original version of the CFQ was translated into Brazilian Portuguese by two independent researchers, analyzed by a multidisciplinary board of experts, and back-translated into English. The final version was administered to 225 adults. Validity was assessed by correlation with the Self Reporting Questionnaire-20 (SRQ-20) and the Adult Attention Deficit/Hyperactivity Disorder Self-Report Scale (ASRS-18). Reliability was analyzed by calculating internal consistency and test-retest stability. Results: The adapted version of the CFQ showed significant correlations with SRQ-20 (r = -0.311), ASRS-18 inattention (r = 0.696), and hyperactivity/impulsivity (r = 0.405) scores. Reliability analysis suggests high internal consistency (0.906) and temporal stability (0.813). Conclusion: The Brazilian Portuguese version of the CFQ showed moderate correlations with other measures of mental health, as well as adequate reliability.

Household task demands for quiet and focused behavior facilitate performance by ADHD youth / Demandas de tarefas domésticas por comportamento quieto e focado facilitam o desempenho de jovens com TDAH

ABSTRACT This study evaluated the associations among symptoms of attention-deficit/hyperactivity disorder (ADHD) and of oppositional defiant disorder (ODD) in children and adolescents’ performance in household tasks and assistance provided by caregivers. Parents of children from 6 to 14 years old with ADHD (n = 67) were interviewed with the Children Helping Out: Responsibilities, Expectations, and Supports (CHORES) instrument. Significant correlations were found between symptoms of ODD and assistance in self-care tasks (r = −0.31; p = 0.01); symptoms of hyperactivity correlated with assistance in self-care (r = −0.30, p = 0.01); and family-care (r = −0.25, p = 0.04) tasks. Age was directly associated with the number of tasks performed by children and inversely related to the assistance provided by caregivers. A greater number of ODD symptoms resulted in more household assistance from caregivers. Characteristics of ODD symptoms, such as disobedience and hostility in the face of authority, may limit these children in accessing household tasks by their own initiative, requiring assistance from caregivers.

RESUMO Este estudo avaliou transversalmente a correlação entre sintomas de transtorno de déficit de atenção e hiperatividade (TDAH) e de oposição com desempenho de crianças e adolescentes nas tarefas domésticas e assistência disponibilizada pelos cuidadores. Pais de crianças e adolescentes com TDAH (n = 67), de 6 a 14 anos, foram entrevistados com o children helping out: responsibilities, expectations and supports (CHORES). Foram encontradas correlações significativas entre sintomas de oposição e assistência em cuidado próprio (r = -0,31; p = 0,01) e de hiperatividade com assistência em cuidado próprio (r = -0,30, p = 0,01) e em cuidado familiar (r = -0,25, p = 0,04). Idade está diretamente correlacionada ao número de tarefas desempenhadas pela criança e inversamente associada à assistência disponibilizada pelos cuidadores. Maior número de sintomas de oposição resultou em maior assistência disponibilizada. Características dos sintomas de oposição, como a desobediência e hostilidade frente às autoridades, são limitantes para que essas crianças acessem as tarefas por iniciativa própria, demandando maior assistência dos cuidadores.

ADHD inattentive symptoms mediate the relationship between intelligence and academic performance in children aged 6-14

Objective: Fluid intelligence and the behavioral problems of attention-deficit/hyperactivity disorder (ADHD) are related to academic performance, but how this association occurs is unclear. This study aimed to assess mediation and moderation models that test possible pathways of influence between these factors. Methods: Sixty-two children with ADHD and 33 age-matched, typically developing students were evaluated with Raven's Colored Progressive Matrices and the spelling and arithmetic subtests of the Brazilian School Achievement Test. Dimensional ADHD symptomatology was reported by parents. Results: Our findings suggest that fluid intelligence has a significant impact on academic tests through inattention. The inattentive dimension was the principal behavioral source of influence, also accounting for the association of hyperactive-impulsive manifestations with school achievement. This cognitive-to-behavioral influence path seems to be independent of diagnosis related group, and gender, but lower socioeconomic status might increase its strength. Conclusion: Fluid intelligence is a relevant factor in the influence of ADHD behavioral symptoms on academic performance, but its impact is indirect. Therefore, early identification of both fluid intelligence and inattentive symptoms is of the utmost importance to prevent impaired academic performance and future difficulties in functioning. .

Psicofarmacogenética / Psychopharmacogenetics

Doenças psiquiátricas são patologias crônicas, recorrentes e promotoras de desarranjo e custo social extenso. A psicofarmacologia apresenta um número crescente de medicações eficazes e sua evolução acontece no sentido de aumentar a eficácia do tratamento de pacientes refratários, assim como reduzir os freqüentes efeitos colaterais associados com as medicações tradicionais. A farmacogenética é uma ciência relativamente recente que estuda as influências genéticas na resposta a droga e que pode vir a ser ferramenta essencial para o entendimento do funcionamento de drogas, assim como dos efeitos colaterais de medicações. Nessa revisão foram levantados os principais achados farmacogenéticos com antipsicóticos e antidepressivos e comentadas as perspectivas da farmacogenética na comunidade científica e clínica no Brasil.
