Free associate norms for 139 European Portuguese words for children from different age groups

In the present study, we present normative ratings of free association for 139 European Portuguese (EP) words among 7- to 8-, 9- to 10-, and 11- to 12-year-old children attending the 3rd, 5th, and 7th grades of elementary and middle school in Portugal. For each word, five indices are presented: (a) the percentage of associates, (b) the strength of the first associate, (c) the strength of the second associate, (d) the distance between the first and second associates, and (e) the percentage of idiosyncratic responses. Additionally, grade-level frequency values for each word from the ESCOLEX database (Soares et al., in press) are also provided. As expected, the results revealed developmental changes in the knowledge organization of the children, which occurred at the ages of 9–10 (5th grade) and remained stable in the 11- to 12-year-old children (7th grade). Specifically, we observed a decrease in the percentages of associates and idiosyncratic responses, as well as an increase in the strengths of the first and second associates from the 3rd to the 5th grade. Moreover, a comparative analysis with the previous work of Carneiro, Albuquerque, Fernandez, and Esteves (2004) on EP and Macizo, Gómez-Ariza, and Bajo (2000) on Spanish, for the subsets of common words (16 and 58, respectively), showed that the present norms fit well with previous EP data, but differ from the Spanish data.

Estimation of the bivariate distribution function for censored gap times

ABSTRACT In many medical studies, patients may experience several events during follow-up. The times between consecutive events (gap times) are often of interest and lead to problems that have received much attention recently. In this work, we consider the estimation of the bivariate distribution function for censored gap times. Some related problems such as the estimation of the marginal distribution of the second gap time and the conditional distribution are also discussed. In this article, we introduce a nonparametric estimator of the bivariate distribution function based on Bayes’ theorem and Kaplan–Meier survival function and explore the behavior of the four estimators through simulations. Real data illustration is included.

Adaptação do Inventário de Ciúme Romântico (ICR) para a população Portuguesa

The objective of this study was to adapt a Brazilian instrument for romantic jealousy assessment to the Portuguese cultural context, and to evaluate its psychometric properties. The adapted instrument was answered by 808 participants, divided in two equivalent samples regarding number and gender. Simultaneous factor analysis with those samples showed high similarity both with each other and with previous results obtained with a Brazilian sample. All factors showed reliability indices above 0.8. IRT based analysis revealed a good use of the response categories and showed that the majority of the scales are more discriminative for pathologic jealousy manifestation. It was concluded that the scale shows validity based on internal structure and good reliability, and can be recommended for research purposes.
