Bullying, cyberbullying and mental health: the role of student connectedness as a school protective factor
2021
Traditional bullying and cyberbullying are linked to adverse mental health outcomes. Student connectedness has been recently identified as a potential protective factor in these relationships. Nonetheless, the multilevel nature of these interactions has been frequently overlooked. The present study pretends to fill this gap by exploring the associations between individual levels of bullying and cyberbullying and three adjustment outcomes (i.e., suicidal behavior, symptoms of depression, and self-esteem), as well as the moderating role of the school level of student connectedness on these relationships. The participants in this work were 1,774 students aged 14-18 years (M = 15.70, SD = 1.26)…
The study of Positive and Negative Affect in children and adolescents: New advances in a Spanish version of the PANAS
2019
The study of affective disorders among young population has become increasingly relevant in the last years. The PANAS is a widely used questionnaire devoted to assess positive and negative affect. The main purpose of the current study was to examine the psychometric properties of the Spanish version of the PANAS for children (PANAS). The sample consisted of 1032 children and adolescents aged between 10 and 15 years. The ESEM two factor model (Positive Affect and Negative Affect) was found as the most suitable model. The PANAS scores also showed acceptable internal consistency. The ESEM two factor model was invariant across gender and educational level. Results showed statistically significa…
Screening for depressive symptoms in adolescents at school: New validity evidences on the short form of the Reynolds Depression Scale.
2017
The main purpose of the present study was to assess the depressive symptomatology and to gather new validity evidences of the Reynolds Depression Scale-Short form (RADS-SF) in a representative sample of youths. The sample consisted of 2914 adolescents with a mean age of 15.85 years (SD = 1.68). We calculated the descriptive statistics and internal consistency of the RADS-SF scores. Also, confirmatory factor analyses (CFAs) at the item level and successive multigroup CFAs to test measurement invariance, were conducted. Latent mean differences across gender and educational level groups were estimated, and finally, we studied the sources of validity evidences with other external variables. The…
Programas Educativos Universitarios Para Mayores: Evaluación de su Impacto en la Autopercepción del Apoyo Social y la Salud Mental
2015
Some studies indicate that university programs for older adults can have a positive impact on the participants perceptions of social support and health. However, those studies fail to evaluate these variables with standardized measurement instruments and control groups, both within and outside the program. This study used an experimental group and two control groups that were evaluated at two different moments, using standardized instruments. The results did not confirm the expected beneficial effects of the programs. Thus, it is necessary to continue in-depth research along these lines and explore the effect of socio-affective variables in longitudinal studies. Alguns estudos indicam que o…

Fiabilidad y evidencias de validez de un instrumento para la evaluación de la calidad de los mapas conceptuales
2017
Diversos autores han señalado el interés y la pertinencia de los mapas conceptuales como herramientas para el aprendizaje significativo. Sin embargo, la revisión de la literatura pone de manifiesto la escasez de propuestas dirigidas a la evaluación de los mapas con criterios objetivables y la complejidad de las existentes. El objetivo del presente estudio fue desarrollar un instrumento para la evaluación de los mapas conceptuales en formato rúbrica. De esta manera, se consigue que los alumnos posean una herramienta que permita, mediante indicadores precisos, la evaluación de la calidad tanto de sus ejecuciones como de las ejecuciones realizadas por otros. Se construyó una rúbrica que incluy…
Identifying extended psychosis phenotypes at school: Associations with socio-emotional adjustment, academic, and neurocognitive outcomes
2020
The main goal of the present study was to explore the latent structure of extended psychosis phenotypes in a representative sample of adolescents. Moreover, associations with socio-emotional adjustment, academic achievement, and neurocognition performance across the latent profiles were compared. Participants were 1506 students, 667 males (44.3%), derived from random cluster sampling. Various tools were used to measure psychosis risk, subjective well-being, academic performance, and neurocognition. Based on three psychometric indicators of psychosis risk (schizotypal traits, psychotic-like experiences, and bipolar-like experiences), four latent classes were found: non-risk, low-risk, high r…
Spanish normative data of the Strengths and Difficulties Questionnaire in a community-based sample of adolescents
2022
Background/Objective: The Strengths and Difficulties Questionnaire self-report (SDQ-S) has been extensively used to assess mental health problems among children and adolescents. However, previous research has identified substantial age and country variation on its psychometric properties. The aim of this study was three-fold: i) to evaluate internal structure and measurement invariance of the Spanish version of the SDQ; ii) to analyze age and gender-specific effects on the SDQ subscales; and iii) to provide Spanish normative data for the entire age range of adolescence. Method: Data were derived from two representative samples of adolescents aged 14 to 19 years old, selected by stratified r…
Brief assessment of schizotypal traits: A multinational study
2018
The Schizotypal Personality Questionnaire-Brief (SPQ-B) was developed with the aim of examining variations in healthy trait schizotypy, as well as latent vulnerability to psychotic-spectrum disorders. No previous study has studied the cross-cultural validity of the SPQ-B in a large cross-national sample. The main goal of the present study was to analyze the reliability and the internal structure of SPQ-B scores in a multinational sample of 28,426 participants recruited from 14 countries. The mean age was 22.63. years (SD = 7.08; range 16-68. years), 37.7% (n = 10,711) were men. The omega coefficients were high, ranging from 0.86 to 0.92 for the total sample. Confirmatory factor analysis rev…

2017
Introduction: Suicide is a current public health problem and among the main causes of mortality in adolescents and young adults. The main goal of this study was to analyse suicidal ideation in a representative sample of Spanish adolescents. Specifically, the prevalence rates of suicide ideation, the psychometric properties of the Paykel Suicide Scale (PSS) scores, and the socio-emotional adjustment of adolescents at risk for suicide were analysed. Material and methods: The sample consisted of 1,664 participants (M = 16.12 years, SD = 1.36, range 14-19 years), selected by stratified sampling by clusters. The instruments used were the PSS, the Strengths and Difficulties Questionnaire, the Per…

Effects of an Emotional Education Intervention in Students of University Programs for Older Students
2017
RESUMEN Los programas universitarios para mayores tienen como objetivo la potenciación de las capacidades cognitivas, emocionales y sociales, así como la mejora de la calidad de vida y el bienestar personal. Las competencias emocionales, por su impacto a múltiples niveles, se deben desarrollar y fomentar a lo largo de todo el ciclo vital. No obstante, hasta el momento, en España existen escasos trabajos que implementen programas de intervención de educación emocional para mayores y que al mismo tiempo evalúen empíricamente su posible impacto. El principal objetivo de este trabajo fue examinar el efecto de un programa de educación emocional en alumnos de un programa universitario para mayore…
Programas Educativos Universitarios Para Mayores: Evaluación de su Impacto en la Autopercepción del Apoyo Social y la Salud Mental
2015
Algunos estudios indican que los programas universitarios para mayores pueden tener un impacto positivo en la autopercepción del apoyo social y la salud de los participantes. Sin embargo, dichos estudios no evalúan estas variables con instrumentos de medida estandarizados y grupos de control dentro y fuera del programa. En el presente trabajo se utilizó un grupo experimental y dos grupos control que fueron evaluados en dos momentos con instrumentos estandarizados. Los resultados no confirmaron los efectos beneficiosos esperados de los programas. Es necesario seguir profundizando en esta línea de actuación y explorar el efecto de variables socioafectivas en estudios longitudinales. Some stud…
