It aimed to gather evidence psychometrics of the Family Resiliency Assessment Scale (FRAS). Two studies were carried out with participants from different states in Brazil. In the first (n = 314), the majority female (56.4%), with an exploratory factor analysis being performed, which suggested a three-factorial structure, with adequate precision. The study 2 (n = 336), the majority female, who undergoing hemodialysis (46.4%). Confirmatory factor analysis corroborated the structure tetra-factorial (family communication and problem solving, maintaining a positive outlook, using social resources and economics, and family spirituality). Therefore, the results showed that the reduced version of FRAS can be an alternative to assess family resilience and its correlates.

Academic satisfaction has been studied from different perspectives that considerate distinct ways of measurement. However, the plurality of evaluated facets prevents a more parsimonious assessment of the general students’ academic satisfaction. In the article, we aimed to provide psychometric evidence of the validity and reliability for the AMSS in Brazil in two studies (N = 893). In Study 1, an exploratory factor analysis and item parameters (Item Response Theory) support the one-factor solution and the suitability of the six items. Moreover, evidence for factorial invariance across gender and convergent validity with the PANAS and with the SWLS was also presented in Study 2. In conclusion, the present paper provides evidence of the adequacy of the AMSS to evaluate global satisfaction with the academics course in Brazil.

Speech accuracy is an indicator for evaluating the language of children with cochlear implant (CI). Verifying the teaching that increases this accuracy and how efficiency measures can be adopted are relevant questions. The current study evaluated the acquisition of speech accuracy, using pictures of scenes as controls. Sentences were employed after equivalence-based instruction. Eight children with CI and who were readers participated in the study. The sentences had the following structure: [subject]-[verb]-[object]. The teaching included selecting pictures and constructing printed sentences, conditionally to dictated sentences. Naming and reading was monitored by multiple probes. Two judges transcribed the participants’ vocalizations and the accuracy was measured by the correspondence with target-phonemic units of sentences. All the participants increased the speech accuracy in respon...

La rápida globalización y la creciente necesidad de comunicación interlingüística requieren corpus modernos y en tiempo real para ayudar a los estudiantes de idiomas. Los métodos tradicionales para crear dichos corpus, especialmente en español, son inadecuados debido a su incapacidad para procesar la gran cantidad de datos no estructurados disponibles en internet. En este estudio se exploran las metodologías de inteligencia artificial (IA) para la adquisición automática de documentos en español de la web, preprocesándolos y clasificándolos con el fin de construir un corpus vasto y flexible para el aprendizaje del español. La investigación aplica el rastreo web mediante el framework Scrapy para recopilar datos, que luego se limpian y clasifican utilizando modelos avanzados de procesamiento del lenguaje natural (PLN). En concreto, el estudio emplea el algoritmo BERT (Bidirec...

The UPPS-P scale is widely used to assess impulsivity. For this reason, the psychometric properties of the extensive version of UPPS-P were analyzed from the Rasch polytomous model. Eight hundred Argentine adolescents aged 12 to 18 years participated in the study. As a result, it was found that the dimensions of the UPPS-P presented an adequate fit to the Rasch model, adequate levels in the Person Separation Index (PSI), some items with local dependence and an adequate level of unidimensionality. It is concluded that the scale is a valid instrument to assess impulsivity in adolescents; therefore, a conversion table with interval scores is presented to increase the measurement precision of the instrument.

The judicial systems require psychologists to evaluate subjects who serve sentences in penitentiary establishments in order to assess the possibility of reinsertion in society. Consequently, prison psychologists have developed techniques and procedures for assessing the risk of violent behavior based on the identification of risk factors. The objective of this study was to adapt the first instrument for assessing the risk of violence in the Peruvian prison context. Content validity was evidenced by expert judgment and with a sample of 303 inmates, construct validity was identified through exploratory and confirmatory factor analysis. Finally, the diagnostic accuracy was established by means of the ROC curve. The results indicate that the adaptation of the EVCV-RR is an adequate instrument to assess the criminogenic risk.
