Using Mixture Factor Analysis to Counter Faking
Self-reports (SRs) of typical behavior are often the only existing feasible method to gather data on important drivers of human performance. In applications such as personnel selection, SRs are vul
Asymptotic is Better than Bollen-Stine Bootstrapping to Assess Model Fit: The Effect of Model Size on the Chi-Square Statistic
Previous research on bootstrapped p-values for the chi-square test of model fit has been limited to small models (around 10 variables), revealing that these p-values are accurate provided the sample size is not too small. For small sample sizes (N < 100), usual p-values, obtained using asymptotic methods, are more accurate. However, as the number of variables increases asymptotic p-values incorrectly suggest that models fit poorly. We investigate…
Teacher-student relationships and adolescents' school satisfaction: Behavioural engagement as a mechanism of change
BackgroundTeacher-student relationships have been linked to various aspects of students' school functioning, including social-emotional well-being in school, but the underlying mechanisms need more investigation.AimsIn this study, we analysed longitudinal data to test if students' classroom behavioural engagement was a potential mechanism of change that explained how teacher-student relationships affect student school satisfaction.SampleWe used a…
Psychopathy Checklist: Youth Version psychometric properties in an Item Response Theory polytomous model
This study assessed the applicability of the Psychopathy Checklist: Youth Version in a sample of teenagers confined in socio-educational institutions. Using an Item Response Theory approach, item properties of this instrument were reviewed using the generalized partial credit model. Eight of the original twenty items of the original instrument were discarded due to low discrimination parameters. As expected, the most discriminating items in the a…
