| Abstract: | The Infant Behavior Questionnaire–Revised Very Short Form (IBQ–R VSF; Putnam, Helbig, Gartstein, Rothbart, &; Leerkes, 2014 Putnam, S. P., Helbig, A. L., Gartstein, M. A., Rothbart, M. K., &; Leerkes, E. (2014). Development and assessment of short and very short forms of the Infant Behavior Questionnaire–Revised. Journal of Personality Assessment, 96, 445–458. doi:10.1080/00223891.2013.841171Taylor &; Francis Online], Web of Science ®] , Google Scholar]) is a newly published measure of infant temperament with a 3-factor structure. Recently Peterson et al. (2017 Peterson, E. R., Waldie, K. E., Mohal, J., Reese, E., Atatoa Carr, P.E., Grant, C. C., &; Morton, S. M. B. (2017). Infant Behavior Questionnaire–Revised Very Short Form: A new factor structure's associations with parenting perceptions and child language outcomes. Journal of Personality Assessment. Advance online publication. doi:10.1080/00223891.2017.1287709Taylor &; Francis Online] , Google Scholar]) suggested that a 5-factor structure (Positive Affectivity/Surgency, Negative Emotionality, Orienting Capacity, Affiliation/Regulation, and Fear) was more parsimonious and showed promising reliability and predictive validity in a large, diverse sample. However, little is known about the 5-factor model's precision across the temperament dimensions range and whether it discriminates equally well across ethnicities. A total of 5,567 mothers responded to the IBQ–R VSF in relation to their infants (N = 5,639) between 23 and 52 weeks old. Using item response theory, we conducted a series of 2 parameter logistic item response models and found that 5 IBQ–R VSF temperament dimensions showed a good distribution of estimates across each latent trait range and these estimates centered close to the population mean. The IBQ–R VSF was also similarly precise across 4 ethnic groups (European, Māori, Pacific peoples, and Asians), suggesting that it can be used as comparable measure for infant temperament in a diversity of ethnic groups. |
