ResumoEste trabalho visou analisar a pontuação dos subtestes Semelhanças, Vocabulário e Compreensão do WISC-III, tendo em vista que podem envolver maior subjetividade do avaliador. Participaram do estudo 42 psicólogos de diferentes Estados do Brasil, os quais corrigiram as respostas de 6 protocolos do teste selecionados aleatoriamente da amostra de padronização ao contexto brasileiro. Tomando-se como referência os escores totais, o subteste Vocabulário apresentou maior variabilidade nas pontuações, seguido por Compreensão. Considerando-se o total de itens analisados em cada subteste, Semelhanças apresentou a maior concordância entre os avaliadores. Entretanto, os resultados evidenciaram que os três subtestes envolvem a subjetividade do avaliador na pontuação das respostas. Palavras-chave: WISC-III; Psicometria; Subtestes Verbais.
AbstractIn all psychological tests, scoring should be of concern for examiners because the accuracy of results depends, at some extent, on the quality of the correction. This work aims to examine the correction, by different psychologists, of the scores for the Wechsler Intelligence Scale for Children (WISC-III) subtests of Similarities, Vocabulary and Comprehension since these are the subtests where examiner's subjectivity seemingly most influences scoring. Forty two psychologists from different states in Brazil participated in this study. They corrected the answers of six test protocols randomly selected from a standardization sample for the Brazilian context. Taking as reference the total scores, the Vocabulary subtest showed greater variability in score, followed by the Comprehension one. Considering the total number of items tested in each subtest, Similarities had the highest agreement among raters. The results showed that all the three subtests involve subjectivity on behalf of the examiner to score the answers. Continuing in this study, we also aim to determine test reliability based on interrater agreement. Keywords: WISC-III; Psychometric; Verbal Subtests. O teste psicológico é uma ferramenta capaz de auxiliar no diagnóstico e na tomada de decisão do psicólogo. Entretanto, para garantir sua eficácia, é condição essencial que este instrumento de aferição esteja calibrado e que os usuários tenham domínio dos procedimentos de uso e interpretação. Identificar as limitações da técnica e as dificuldades provenientes de seu emprego é uma tarefa importante que vai auxiliar seus usuários a minimizar os erros de estimação. A proposta deste trabalho é apontar os problemas envolvidos na etapa de correção (pontuação) de uma técnica amplamente empregada para avaliar a inteligência de crianças e adolescentes.Segundo Pasquali (1999), a melhor maneira de observar um fenômeno psicológico é através da medida. Esse pressuposto é reforçado por Alchieri e Cruz (2003), para os quais os testes são operações empíricas utilizadas pela Psicologia a fim de estudar as diferentes manifestações do seu objeto, os processos psíquicos e os comportamentos deles decorrentes.A medida é um procedimento empírico e ...
The initial stages of this manuscript were presented as a research project, in a synthetic way, at the XII Brazilian Congress of Cognitive Therapies ("Cross-cultural adaptation of instruments for the assessment of juvenile (hypo)mania: semantic validation", 2019) and at the 9th Brazilian Congress of Psychological Assessment ("Cross-cultural adaptation of assessment instruments for bipolar disorder in children and adolescents: semantic validation", 2019).
Smoking accounts for 24% of deaths in the general population and is also the factor that explains the biggest amount of years of life lost. It is important to understand the expectations regarding smoking behavior. The present study aimed to validate the Short Form of the Smoking Consequences Questionnaire (S-SCQ) for a Brazilian version. The Researchers did the process of semantic adaptation to language and national context. The S-SCQ was applied in a sample of 129 people. The next step was to perform psychometric analyses for the set of 21 items. Exploratory Factor Analysis, with pairwise treatment for missing cases, was used to achieve construct validity. To carry out Factor Analysis, the method of Principal Component Analysis (PCA) was used initially. Afterwards, Principal Axis Factoring (PAF) using Varimax rotation with Kaiser normalization was applied. The reliability of the total scale (21 items) showed a Cronbach alpha index of 0.851 and a 0.870 Lambda2 of Gutmann. Quite satisfactory rates were also observed in the subscales. Similarly, the item-overall correlation values also confirmed the scale’s good reliability indices.
