Alcohol Abuse and Physical Violence towards a Partner: How Can We Attenuate the Relationship? A Study on Emotional Dysregulation in Adolescents.

Background: The previous literature has revealed the relationship between alcohol abuse and violent behaviours; however, the results are not always conclusive, highlighting the need to explore other variables that allow us to establish risk profiles.

Aim: The goal is to examine whether the relation between alcohol abuse and physical violence towards a partner can be influenced (moderate) by difficulties in emotional regulation.

Setting: A public high school in Manabí (Ecuador).

Morphological and molecular characterization of parabasilids isolated from ex situ nonhuman primates and their keepers at different institutions in Brazil.

Intestinal protozoa, which can be asymptomatic or cause diarrhea, dysentery and even death, are among the main agents that affect nonhuman primates (NHPs) kept under human care. Nevertheless, information on the molecular and morphometric profiles of parabasilids in the Neotropics is still scarce. In this context, the objective of this study was to isolate the Parabasalia protozoa detected in the feces of NHPs and their keepers in Pavlova and TYSGM9 media and to characterize the isolates by molecular biology and morphometry.

Behavioral economic analysis of legal and illegal cannabis demand in Spanish young adults with hazardous and non-hazardous cannabis use.

Background: In October 2021, a legal framework that regulates cannabis for recreational purposes in Spain was proposed, but research on its potential impacts on cannabis use is currently limited. This study examined the reliability and discriminant validity of two Marijuana Purchase Tasks (MPTs) for measuring hypothetical legal and illegal cannabis demand, and to examine differences in demand of both commodities in young adults at hazardous vs. non-hazardous cannabis use risk levels.

The sample consisted of 7379 students (47.

Should we Help our Children with Homework? A Meta-Analysis Using PISA Data.

Background: The role of homework in students' academic performance is a widely debated topic about which there is no definitive answer. The objective of this study was to analyse the importance of parental help with homework in academic achievement, testing its cultural invariance (by country), academic invariance (by subject), and the stability of its effects over time.

Method: A meta-analysis was performed using the results of PISA evaluations from 2009, 2012, 2015, and 2018 from countries which applied the family PISA questionnaire.

[Decalogue for the Factor Analysis of Test Items].

Unlabelled: Decalogue for the Factor Analysis of Test Items.

Background: In the study of the psychometric properties of the items of a test, a fundamental aspect is the analysis of their dimensional structure. The objective of this work is to provide some guidelines that allow the factor analysis of the items to be carried out in a rigorous and systematic way.

Problematic Social Network Use: Structure and Assessment.

Using social networks (SNs) inappropriately can lead to psychological problems. The objective of this study was to develop a new measuring instrument of problematic use of SNs. The sample comprised 1003 participants over 18 years old ( = 42.

[Empirically Supported Psychological Treatments for Children and Adolescents: State of the Art].

Unlabelled: Empirically Supported Psychological Treatments for Children and Adolescents: State of the Art.

Background: The empirical evidence accumulated on the efficacy, effectiveness, and efficiency of psychotherapeutic treatments in children and adolescents calls for an update. The main goal of this paper objective was to carry out a selective review of empirically supported psychological treatments for a variety of common psychological disorders and problems in childhood and adolescence.

Influence of Dental Pulp Harvesting Method on the Viability and Differentiation Capacity of Adult Dental Pulp-Derived Mesenchymal Stem Cells.

Objective: To compare two pulp harvesting methods for stem cell expansion, namely, conservative pulpotomy and pulpectomy from exodontia.

Method: Ten freshly extracted sound third molars from five patients were selected. Five were used in the control group, where pulp harvesting was performed by exodontia and the remaining teeth were used in the test group, where the pulp was harvested by conservative pulpotomy (preserving the tooth).

Uniform trichromacy in Alouatta caraya and Alouatta seniculus: behavioural and genetic colour vision evaluation.

Primate colour vision depends on a matrix of photoreceptors, a neuronal post receptoral structure and a combination of genes that culminate in different sensitivity through the visual spectrum. Along with a common cone opsin gene for short wavelengths (sws1), Neotropical primates (Platyrrhini) have only one cone opsin gene for medium-long wavelengths (mws/lws) per X chromosome while Paleotropical primates (Catarrhini), including humans, have two active genes. Therefore, while female platyrrhines may be trichromats, males are always dichromats.

Academic resilience in European countries: The role of teachers, families, and student profiles.

Academic resilience is a student's ability to achieve academic results significantly higher than would be expected according to their socioeconomic level. In this study, we aimed to identify the characteristics of students, families, and teacher activities which had the greatest impact on academic resilience. The sample comprised 117,539 fourth grade students and 6,222 teachers from 4,324 schools in member states of the European Union that participated in the PIRLS 2016 study.

Aim: Develop two psychometrically sound questionnaires to assess users' and relatives' opinions of Person-Centred Care. Evaluate the convergence between the perspectives of the different agents involved in Person-Centred Care in the older people: Users, relatives and staff. Examine the relationships between Person-Centred Care and care quality and the users' perceived psychological well-being.

Grit Assessment: Is One Dimension Enough?

Grit is one of the non-cognitive variables that has received the most attention in recent years given its relationship to and influence in various aspects of life. There are very few reliable, valid instruments to evaluate it in Spanish-speaking countries. Because of that, the aim of this study is the development and validation of a new scale to evaluate grit in Spanish-speaking contexts.

Predicting Student Well-Being: Network Analysis Based on PISA 2018.

The latest trends in research extend the focus of school effectiveness beyond students' acquisition of knowledge and skills, looking at aspects such as well-being in the academic context. Although the concept of well-being itself has been defined and measured in various ways, neither its dimensions nor the relationships between the components have been clearly described. The aim of the present study was to analyse how the elements of well-being interact and determine how they are influenced by school factors.
