While self-assessment is a widely explored area in educational research, our understanding of how students assess themselves, or in other words, generate self-feedback, is quite limited. Self-assessment process has been a black box that recent research is trying to open. This study explored and integrated two data collections (secondary and higher...

People experiencing homelessness endure significant structural, social, and personal stigma; suffer numerous negative stereotypes; and face unequal access to health care services and resources, resulting in poorer health outcomes. Despite its significance, no national studies on stigma have been conducted in Spain with a representative sample. This...

Background: Stigma towards people with intellectual disability affects various aspects of their lives, including access to employment, housing, health and social care services. Furthermore, this stigma reduces their social opportunities and is even reflected in laws that diminish their autonomy. Due to the practical significance of this issue, the...

Background: Video game playing (VGP) is an increasingly common leisure activity among children and adolescents, although in some cases, it is accompanied by problems due to misuse. Method: A sample of 2884 children and adolescents aged between 12 and 20, representative of the Community of Madrid (Spain), were studied using a cluster analysis to exp...

In recent times, growing concern has arisen regarding the utilization of technology, video games, and the emergence of internet gaming disorder (IGD), particularly among young adolescents. This worry arises from the ambiguity in distinguishing between “normal” and “problematic” video game behavior, despite efforts to establish clear criteria for de...

Previous research has demonstrated the benefits of peer feedback for improving student work. Gender, as an individual characteristic, is now receiving increased attention due to its influence on the peer feedback process. This study examined the effects of gender and peer assessment training on the amount and content of peer feedback provided by as...

Mental health problems, broadly understood, are highly prevalent [...]

This study explored the effects of three factors (feedback occasion, type of feedback, and year level) on self-efficacy and emotions when university students self-assessed. Higher education students from three different year levels self-assessed their performance on a writing task two times (before and after receiving feedback). Self-efficacy and e...

Background: Mental health stigma is a relevant phenomenon with implications for the people who suffer from it. Despite its importance, no studies have been carried out in Spain at national level with a representative sample of the population. Aims: The aim of this research is to analyze the stigma associated with MHPs in a representative sample...

Clinical trials are the backbone of medical scientific research. However, this experimental strategy has some drawbacks. We focused on two issues: (a) The internal validity ensured by clinical trial procedures does not necessarily allow for generalization of efficacy results to causal claims about effectiveness in the population. (b) Statistical si...

During the last decade, gambling (online and offline) regulation has become a social and epidemiological problem all around Europe. The aftermaths of this addiction have increased since the so-called “responsible gambling law”, in the second decade of the 21st century. The Overton window (OW) strategy is a political theory that describes how the pe...

Due to the recognition of the high prevalence and widespread effects of trauma, trauma-informed care (TIC) framework has emerged to address its impact and prevent retraumatization in the systems of care. Since organizational support has been identified as crucial in TIC implementation and sustainability, this systematic review assessed the status q...

Inferential analysis using null hypothesis significance testing (NHST) allows accepting or rejecting a null hypothesis. Nevertheless, rejecting a null hypothesis and concluding there is a statistical effect does not provide a clue as to its practical relevance or magnitude. This process is key to assessing the effect size (ES) of significant result...

En la última década se ha estudiado la crisis de replicabilidad: tanto los procesos como las soluciones. Dicho estudio ha supuesto una reflexión sobre el modo de hacer ciencia en psicología. En este trabajo se pretende resumir el estado actual de la crisis en replicabilidad enfocándolo hacia los estudios de validación de instrumentos de medición en...

Structural equation models (SEM) are useful tools for proposing theoretical relationships, causal or not, between multiple variables. However, they do not allow us to confirm the existence of cause-effect relationships in the absence of an experimental design. We evaluated the occurrence of inadequate expressions of causality in non-experimental ar...

The Survey of Autobiographical Memory (SAM) scale is an easy-to-administer self-report measure of Autobiographical Memory (AM) abilities. The aim of this study was to obtain evidence of psychometric validity of the SAM in the Spanish population, specifically evidence of internal structure and reliability (factor) and evidence of relationship with o...

Gaming is increasingly prevalent among young people, and Gaming Disorders are a growing concern. Maladaptive cognitions related to gaming may affect the psychological development of young people. We examined psychometric properties of the Dysfunctional Cognitions Gaming (DCG) Scale in Spanish adolescents and young adults. We applied 16 items of the...

p> Background: Social stigma towards people with mental health problems, homeless people or people with intellectual disabilities leads to a significant restriction of their human rights.

Purpose Spinal Muscular Atrophy (SMA) Type II is a neurodegenerative disease that leads to progressive muscle weakness. It prevents children from walking and affects their respiratory function and their activity tolerance, among other health problems. We aimed to assess the activity tolerance showed by a child with SMA using a pediatric gait exoske...

The information on the use of Videogames (VG) in general samples fundamentally reflects the characteristics of men, because of their greater participation in VG, making it difficult to identify the characteristics of women and their gaming activity. Objective: To describe the gaming behaviour of adolescent and young women in Madrid, and its relatio...

In recent years, the literature on the relationship between religion and spirituality (R/S) and the health of cancer patients has been flourishing. Although most studies focus on mental health, many study the physical health of these individuals. In order to summarize the findings of these studies, we reviewed the most recent research on this subje...

Trust in God implies the conviction that God looks after a person’s own interests. The first evidence of a relationship between this construct and people’s psychological and emotional health dates back several centuries. However, the literature on this is limited, especially for people with physical health conditions, such as cancer. Therefore, the...

Trust/Mistrust in God have turned out to be two constructs that have great relevance in the study of the relationship between religion, spirituality, and health. In Spain, there are no instruments adapted to measure trust/mistrust in God, which limits the work of researchers interested in these aspects. Therefore, the aim of this study was to valid...

The main goal of scientific research is to explain what causes a phenomenon. However, only well-controlled studies guarantee sufficient internal validity to support causal explanations (i.e., experimental and some quasi-experimental designs). The use of causal claims in non-experimental studies can mislead readers into assuming a cause–effect relat...

Introduction: Between 7-15% of patients with an indication for an implantable cardioverter-defibrillator (ICD) are not eligible for implantation of a subcutaneous implantable cardioverter-defibrillator (S-ICD) on the basis of the result of the conventional left parasternal electrocardiographic screening (LPES). Our objective was to determine the i...

Background: Workplace bullying is considered a major social stressor at work. However, in the Spanish context, there is a lack of measures that allow researchers and practitioners to distinguish between non-targets and targets of workplace bullying. Method: This study reports the psychometric properties, factor structure, and cutoff scores for t...

The inclusion of Internet Gaming Disorder (IGD) in the DSM-5 has generated controversy over its diagnosis, and it therefore seems necessary to establish a clear cut-off point to identify when excessive gaming becomes problematic. Such identification is especially difficult in adolescents and young people, who frequently dedicate a great deal of tim...

We describe the diet of the Iberian common toad (Bufo spinosus) in a locality in central Spain. The sample consisted of individuals that were road-killed in road M-301 between Madrid and San Martín de la Vega during their seasonal migration events in spring and fall.

Self-efficacy is a fruitful construct on psychological research, including the educational setting. The present study is focused on measuring the writing self-efficacy. Specifically, we translated into Spanish the “Self-Efficacy for Writing Scale” (SEWS; Bruning, Dempsey, Kauffman, McKim, & Zumbrunn, 2013) and assessed its psychometric properties o...

In contrast with the extensive use of coaches' pre-game speeches, there is a lack of research on the effects of such commonly used strategy. Different authors have prompted that the pre-game speech contributes to enhanced athletes' self-efficacy. However, previous results are inconclusive. This study examines its effects on young athletes' self-eff...

The capacity of coaches to enable or disable athletes' engagement and ability to reach their potential through the quality of the relationship they develop with them has received substantial research attention, yet the equivalent dyad in dance contexts-the teacher-dancer relationship-has remained relatively unexplored. Thus, the purpose of this pap...

Sport injury is a widely extended morbidity condition. However, epidemiological studies are far from giving a convergent outlook. Moreover, there is a lack of studies comparing relative risks of different groups of sports. The present paper is aimed to carry out a descriptive epidemiological study of sport injuries of athletes from 25 sport modalit...
