Psychometric validation of the audio-guided rBVQ instrument for bullying evaluation among students / Validação psicométrica do instrumento áudio-guiado rBVQ para avaliação de bullying / Validación psicométrica del instrumento audio guiado rBVQ para la evaluación del bullying

The revised Olweus Bully/Victim Questionnaire (rBVQ) is an internationally used instrument to identify bullying, but due to Brazilian students' low proficiency in reading and writing, it had to be adapted for audio-guided use through smartphones. We investigated construct validity, using Confirmatory Factor Analysis (CFA), under a two-correlated factor solution. Participated 1,742 fifth graders and 2,316 seventh graders from 30 public schools in the city of São Paulo. We found excellent fit indices models for both grades (fifth grade: CFI=0.985, RMSEA=0.020; seventh grade: CFI=0.990, RMSEA=0.015), as well as factor loading higher than 0.4 for all items, indicating their relevance to the construct. The rBVQ demonstrated excellent psychometric properties and may help future studies that aim to investigate bullying in populations with similar profiles. In addition, this study innovates by evaluating an audio-guided instrument and using mobile technology. (AU)

O Questionário revisado de bullying de Olweus (rBVQ) é um instrumento internacionalmente utilizado para identificar bullying, mas devido às dificuldades de estudantes brasileiros na leitura e escrita, foi adaptado para uso áudio-guiado em smartphones. Investigou-se a validade do construto por meio de análise confirmatória fatorial em uma solução de dois fatores. Participaram 1742 e 2316 alunos de quintos e sétimos anos de trinta escolas públicas de São Paulo. Encontrou-se excelentes índices de adequação para ambos os anos escolares (quintos: CFI = 0,985; RMSEA = 0,020; sétimos: CFI = 0,990; RMSEA = 0,015) e cargas fatoriais maiores que 0,4 para todos os itens, indicando sua relevância para o construto. O rBVQ demonstrou excelentes propriedades psicométricas e pode ajudar estudos futuros que objetivam investigar bullying em populações com perfis semelhantes. Além disso, este estudo inova por avaliar um instrumento áudio-guiado e utilizando tecnologia móvel. (AU)

El Cuestionario Revisado de Bullying de Olweus (rBVQ) es un instrumento utilizado internacionalmente para identificar bullying, pero debido a las dificultades de estudiantes brasileños en la lectura y la escritura, se ha adaptado su uso por medio de audioguías en smartphones. Se investigó la validez del constructo mediante el Análisis Factorial Confirmatorio, bajo un modelo de dos factores. Participaron 1742 y 2316 estudiantes de quinto y séptimo curso de 30 escuelas públicas de São Paulo. Excelentes tasas de adecuación fueron encontradas para ambos casos (quinto año: CFI=0,985, RMSEA=0,020; séptimo año: CFI=0,990, RMSEA=0,015), además de cargas factoriales superiores a 0,4 para todos los ítems, lo que indica su relevancia para el constructo. El instrumento rBVQ ha presentado excelentes propiedades psicométricas y puede ayudar a futuros estudios pretendan investigar el bullying en poblaciones con perfiles similares. Además, este estudio innova al evaluar un instrumento guiado por audio, empleando la tecnología móvil. (AU)

A new approach to measuring absolute pitch on a psychometric theory of isolated pitch perception: Is it disentangling specific groups or capturing a continuous ability?

Absolute Pitch (AP) is commonly defined as a rare ability that allows an individual to identify any pitch by name. Most researchers use classificatory tests for AP which tracks the number of isolated correct answers. However, each researcher chooses their own procedure for what should be considered correct or incorrect in measuring this ability. Consequently, it is impossible to evaluate comparatively how the stimuli and criteria classify individuals in the same way. We thus adopted a psychometric perspective, approaching AP as a latent trait. Via the Latent Variable Model, we evaluated the consistency and validity for a measure to test for AP ability. A total of 783 undergraduate music students participated in the test. The test battery comprised 10 isolated pitches. All collected data were analyzed with two different rating criteria (perfect and imperfect) under three Latent Variable Model approaches: continuous (Item Response Theory with two and three parameters), categorical (Latent Class Analysis), and the Hybrid model. According to model fit information indices, the perfect approach (only exact pitch responses as correct) measurement model had a better fit under the trait (continuous) specification. This contradicts the usual assumption of a division between AP and non-AP possessors. Alternatively, the categorical solution for the two classes demonstrated the best solution for the imperfect approach (exact pitch responses and semitone deviations considered as correct).
