A recente democratização do crédito tem permitido a população um aumento em seu padrão de consumo, no entanto, o nível de conhecimento financeiro não acompanhou tal crescimento, sendo isso um gatilho para sérios problemas financeiros. O presente estudo teve como objetivo medir o nível de conhecimento financeiro em estudantes universitários, verificando se existe diferença entre calouros e egressos, e, além disso, analisar se existe alguma diferença no domínio do tema entre diversos cursos de graduação como engenharias, de negócios e de humanas (i.e entre alunos com níveis diferentes de educação matemática). Para isso, foi aplicado um questionário que foi refinado utilizando a Teoria de Resposta ao Item (TRI), validada pelo teste DIF (Differential Item Functioning). A amostra contou com 232 estudantes e os resultados concluíram que existe diferença no conhecimento financeiro entre os grupos, sendo maior em estudantes do último ano e em alunos dos cursos de engenharias e de negócios e entre àqueles que possuem uma educação matemática mais sólida, o que pode indicar que a matemática ajuda para uma melhor alfabetização financeira do indivíduo. Adicionalmente, também foram encontradas diferenças de conhecimento financeiro por gênero, raças/etnias, renda e escolaridade dos pais.

Zusammenfassung. In dieser Studie wurde der Test MARKO-D (Mathematik- und Rechenkonzepte im Vorschulalter–Diagnose) mit einer Stichprobe von Kindern aus der deutschsprachigen Schweiz ( N = 555) im ersten und zweiten Kindergartenjahr erprobt und es wurde analysiert, ob sich die Altersnormen der deutschen Stichprobe auf die Schweiz übertragen lassen. Zudem wurde der Test mit einer Teilstichprobe ( n = 87) hinsichtlich Messinvarianz über die Zeit untersucht. Die Ergebnisse des eindimensionalen Rasch-Modells zeigen, dass das Instrument für die Schweiz geeignet ist. Die Testleistungen hängen jedoch vom Kindergartenbesuch ab. Für die Schweiz müssten deshalb nebst Altersnormen auch Normen pro Kindergartenhalbjahr verwendet werden. Die Analyse mittels Differential Item Functioning ergab, dass 17 von 55 Items von großer Messvarianz über die Zeit betroffen sind. Um das Instrument für Längsschnittuntersuchungen einsetzen zu können, müsste es weiterentwickelt werden.

Abstract. Most instruments for the assessment of disordered eating were developed and validated in young female samples. However, they are often used in heterogeneous general population samples. Therefore, brief instruments of disordered eating should assess the severity of disordered eating equally well between individuals with different gender, age, body mass index (BMI), and socioeconomic status (SES). Differential item functioning (DIF) of two brief instruments of disordered eating (SCOFF, Eating Attitudes Test [EAT-8]) was modeled in a representative sample of the German population ( N = 2,527) using a multigroup item response theory (IRT) and a multiple-indicator multiple-cause (MIMIC) structural equation model (SEM) approach. No DIF by age was found in both questionnaires. Three items of the EAT-8 showed DIF across gender, indicating that females are more likely to agree than males, given the same severity of disordered eating. One item of the EAT-8 revealed slight DIF by BMI. DIF with respect to the SCOFF seemed to be negligible. Both questionnaires are equally fair across people with different age and SES. The DIF by gender that we found with respect to the EAT-8 as screening instrument may be also reflected in the use of different cutoff values for men and women. In general, both brief instruments assessing disordered eating revealed their strengths and limitations concerning test fairness for different groups.

Rating Scale Model

This paper presents an IRT analysis of the Beck Depression Inventory which was carried out to assess the assumption of an underlying latent trait common to non-clinical and patient samples. A one parameter rating scale model was fitted to data drawn from a patient and non-patient sample. Findings suggest that while the BDI fits the model reasonably well for the two samples separately there is sufficient differential item functioning to raise serious duobts of the viability of using it analogously with patient and non-patient groups.
