Prevalence of phubbing behaviour in school and university students in Spain.

Objective: This study examined the prevalence of phubbing behavior among school and university students in Spain and analyzed the correlation of phubbing with other indicators of psychological well-being and mental health. Methods: The study sample comprised a total of 1,351 school and university students, with ages ranging from 12 to 21 years. The study used the Phubbing Scale (PS), the Compulsive Internet Use Scale (CIUS), the Rosenberg Self-Esteem Scale (RSE), and the Interpersonal Emotion Regulation Questionnaire (IERQ) for data collection. Results: The results showed evidence of phubbing among approximately half of the students. Statistically significant differences were found based on gender and educational level in the Phone Obsession subscale and the PS total score, with male students and university students scoring higher in their respective parameters. In addition, phubbing was positively correlated with problematic internet use and negatively correlated with self-esteem. Conclusion: Phubbing behavior is highly prevalent among adolescents aged 12-21 years and is positively correlated with low self-esteem and problematic internet use. Developing strategies for addressing this widespread issue at early ages, particularly within the educational context, such as schools, is crucial for implementing preventive measures. The inappropriate use of technological devices, including smartphones, in schools has the potential to negatively affect students' well-being and ability to adapt to school.

Problematic Internet Use in adolescents: New psychometric evidence for the Spanish short form of the Compulsive Internet Use Scale.

OBJECTIVES: Problematic Internet Use (PIU) has become a worldwide problem in recent years. Among screening instruments for PIU, the Compulsive Internet Use Scale (CIUS) is perhaps the most widely used. Psychometric properties of the full CIUS are not convincing, however, and the short form (CIUS-S) has shown promising results, albeit limited to the English version, with little evidence in Spanish. Therefore, the aim of the present work was to study the psychometric properties of the CIUS-S scores in a large sample of Spanish adolescents. METHOD: The sample consisted of 1790 participants, 816 male (45.6%), 961 female (53.7%), and 13 other (0.7%) . Mean age was 15.70 years (SD = 1.26). RESULTS: The five-items one-dimensional model displayed appropriate goodness-of-fit indices. Strong measurement invariance model across age and partial across gender was found. Furthermore, the CIUS-S was positively associated with several indicators of poor well-being and mental health, and negatively associated with prosocial behavior, self-esteem, and feeling of belonging. CONCLUSION: Overall, the CIUS-S scores appear reliable and valid in its Spanish version for adolescent populations, supporting its aim to detect and prevent a problem that has become a major worldwide issue in the last years.

Measuring Violence Behaviours in the Context of Romantic Relationships during Adolescence: New Evidence about the Modified Conflict Tactics Scale.

The main purpose of the present study was to analyze the psychometric properties of the Spanish version of the Modified Conflict Tactics Scale (M-CTS) in adolescents. The M-CTS is a questionnaire that screens for intimate partner violence. Additionally, we studied the association between the M-CTS and attitudes towards violence. The study included a sample of 1248 students in a cross-sectional survey. The M-CTS and the Attitudes Towards Violence (EAV) scale were used. The analysis of the internal structure of the M-CTS revealed that a four-factor structure was the best fitting solution. The M-CTS scores revealed evidence of structural equivalence by gender and age. The McDonald's Omega indices were adequate for both victims and perpetrators models. Moreover, attitudes towards violence were positively correlated with measures of violence manifestations. Results found in the present study confirm the psychometric adequacy of the M-CTS scores and gather new evidence about its internal structure and measurement equivalence for its use in samples of adolescent and young students. The assessment of intimate partner violence may contribute to detect adolescents at risk for different forms of violence in the future.

Problematic Internet Use among adolescents: Spanish validation of the Compulsive Internet Use Scale (CIUS). / Uso Problemático de Internet en adolescentes: Validación en español de la Escala de Uso Compulsivo de Internet (CIUS).

Problematic use of the Internet among adolescents has risen in the last decade. The Compulsive Internet Use Scale (CIUS) is one of the most frequently internationally-used tools developed to assess Problematic Internet Use (PIU). However, evidence concerning its validity and reliability in its Spanish version for the adolescent population is currently lacking. Thus, the main goal of the present study was to analyse the psychometric properties of CIUS scores in a large sample of Spanish adolescents. The sample consisted of 1,790 participants (53.7% female, mean age = 15.70 years old, SD = 1.26). The one-dimensional model displayed appropriate goodness of fit indices after error covariance of five items were allowed to correlate. Strong measurement invariance was found for the one-dimensional model across age and gender. The McDonald's Omega coefficient for the total score was 0.91. Furthermore, PIU was positively associated with different indicators of poor wellbeing and psychological difficulties and negatively associated with prosocial behaviour, self-esteem and sense of belonging to the educational centre. The study provided evidence of validity for the CIUS, confirming its utility for screening PIU in non-clinical adolescents.

La Escala de Uso Compulsivo de Internet (Compulsive Internet Use Scale, CIUS) es uno de los instrumentos más empleados a nivel internacional para evaluar el Uso Problemático de Internet (UPI). Sin embargo, no existen evidencias de validez y fiabilidad de las puntuaciones de la versión española en población adolescente. Por ello, el principal objetivo de este estudio fue analizar las propiedades psicométricas de las puntuaciones de la CIUS en una muestra representativa de adolescentes españoles. La muestra contó con 1.790 participantes (53,7% mujeres, edad media = 15,70 años, DT = 1,26). El análisis de la estructura interna del instrumento mostró unos índices de bondad de ajuste apropiados para el modelo unidimensional después de que se permitiera correlacionar la covarianza de errores de cinco ítems. Se encontró invarianza de medición fuerte para el modelo unidimensional en las variables de edad y género. El coeficiente Omega de McDonald para la puntuación total fue 0,91. Además, el UPI se asoció positivamente con diferentes indicadores de malestar y dificultades psicológicas y negativamente con el comportamiento prosocial, la autoestima y el sentido de pertenencia al centro educativo. Este estudio arroja evidencias de validez de la CIUS, y sugiere que puede ser una herramienta apropiada para medir el UPI en adolescentes de la población general.

Spanish normative data of the Strengths and Difficulties Questionnaire in a community-based sample of adolescents: Datos normativos españoles del Cuestionario de capacidades y dificultades (SDQ) en una muestra comunitaria de adolescentes.

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 random cluster sampling years (N = 3378). Results: The reliability of the Total difficulties score was satisfactory, but some subscales showed lower levels of internal consistency. Confirmatory factor analysis supported the original five-factor model. Finally, results revealed that SDQ scores were influenced by the gender and the age of participants; thus, the normative banding scores and cut-off values were provided accordingly. Conclusions: This study validates the Spanish SDQ-S for the entire age range of adolescence. However, more cross-country and cross-age research is needed to better understand the inconsistent findings on SDQ reliability.

Neurocognitive Functioning in Adolescents at Risk for Mental Health Problems.

BACKGROUND: The main goal of the study was to assess the neurocognitive performance in adolescents at high psychometric risk for mental health problems. METHOD: A sample of 48 participants at high risk for mental disorders and an age-gender matched healthy comparison group of 48 adolescents were identified from a community-derived sample of 1,509 adolescents. The Strengths and Difficulties Questionnaire problems and the University of Pennsylvania Computerized Neuropsychological Test Battery for children (included 14 tasks assessing five neurobehavioral domains: executive functions, episodic memory, complex cognition, social cognition, and sensorimotor speed) were used. RESULTS: Relative to healthy comparison participants, individuals at high risk showed significant impairments across almost all neurocognitive domains (executive functions, episodic memory, complex cognition, social cognition, and sensorimotor speed). CONCLUSIONS: These findings demonstrate that neurocognitive impairments can be shown in adolescents at high psychometric risk for mental health problems before the onset of more severe psychological problems.

Study of Positive and Negative Affect and Neurocognitive Functioning in Adolescents.

The main purpose of the present work was to study neurocognitive performance of adolescents at risk for emotional difficulties. The sample included a total of 1,509 adolescents from stratified random cluster sampling. Derived from this sample, a group of high-risk (n = 92) and a comparison group (n = 92) were selected based on the short version of the Positive and Negative Affect Schedule (PANAS) for comparison on the University of Pennsylvania computerized neuropsychological test battery for children (PENN). A Multivariate analysis of covariance (MANCOVA) was performed taking the scores on the PENN as dependent variables and the two groups derived from the scores of the PANAS (at risk vs. comparison) as a fixed factor. Adolescents at high risk of presenting affectivity problems showed statistically significant differences in several different neurocognitive domains, in accuracy, λ = .820, F(9, 160,000) = 3.913, p < .01, partial η² = .180; speed, λ = .502, F(5, 88,000)= 17.493, p < .01, partial η² = .498; and efficiency, λ = .485, F(4, 89,000) = 23.599, p <.01, partial η² = .515. The high risk group showed lower neurocognitive performance than the comparison group. In addition, a positive statistically significant correlation was found between all the neurocognitive competences (p < .05). Results found in this study reveal that neurocognitive impairments can be shown in adolescents at psychometric high risk for emotional problems before transition to more severe psychological problems.

The Satisfaction with Life Scale in Adolescent Samples: Measurement Invariance across 24 Countries and Regions, Age, and Gender.

Measurement of adolescent life satisfaction across cultures has not received much attention in previous empirical research. The present study evaluated measurement invariance of the Satisfaction with Life Scale (SWLS) among adolescents in 24 countries and regions (N = 22,710; age range = 13-19 years; 53% female). A single-factor model with residual covariance between a pair of items tapping past life satisfaction fitted well in 19 countries and regions and showed a partial metric invariance. In a subset of nine countries and regions, partial scalar invariance was supported. Partial metric invariance across all 24 countries and regions was achieved when custom model modifications in five countries and regions were included. Three SWLS items showed evidence of noninvariance across cultures. The measurement model was found to operate similarly across gender and age. Our findings suggest that caution is needed when using the SWLS for measuring life satisfaction among adolescents from different cultures.

Bullying, Cyberbullying and Mental Health: The Role of Student Connectedness as a School Protective Factor.

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), of which 53.7% were female, from 31 secondary schools in Spain. We used previously validated self-reported questionnaires in this study. Traditional victimization and cybervictimization, as well as cyberbullying, were positively related to suicidal behavior and depression, and were negatively related to self-esteem. Conversely, individual levels of student connectedness were associated with lower levels of suicidal behavior and depression, and with higher levels of self-esteem. Moreover, school levels of student connectedness buffered the adjustment problems experienced by victims of cyberbullying. These findings highlight the importance of student connectedness as a possible target for school-based cyberbullying prevention.

El acoso escolar y el ciberbullying están asociados a efectos adversos para la salud mental. La cohesión entre estudiantes se ha identificado recientemente como un potencial factor protector respecto a este tipo de relaciones. No obstante, con frecuencia se ha pasado por alto la naturaleza multinivel de estas interacciones. El presente estudio pretende llenar este vacío explorando la asociación entre el nivel individual de acoso y ciberbullying y tres indicadores de ajuste (i.e., conducta suicida, síntomas de depresión y autoestima), así como el papel moderador del nivel escolar de cohesión estudiantil en estas relaciones. Los participantes fueron 1,744 estudiantes de 14-18 años (M = 15.70, DT = 1.26), de los cuales el 53.7% eran mujeres, de 31 centros de educación secundaria de España. En el estudio se utilizaron autoinformes previamente validados. La victimización tradicional y la cibervictimización, así como el ciberbullying, se relacionaron positivamente con la conducta suicida y la depresión y negativamente con la autoestima. Por el contrario, los niveles individuales de cohesión entre estudiantes se asociaron con niveles más bajos de conducta suicida y depresión y con niveles más elevados de autoestima. Además, los niveles escolares de cohesión entre estudiantes amortiguaron los problemas de adaptación experimentados por las víctimas de ciberbullying. Estos hallazgos destacan la importancia de la cohesión entre estudiantes como un posible objetivo de cara a la prevención del ciberbullying.

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

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. METHOD: A review was carried out of the psychological treatments for different psychological disorders and problems in social-emotional or behavioral adjustment in the child-adolescent population according to the Spanish National Health System (Clinical Practice Guidelines) levels of evidence and degrees of recommendation. RESULTS: The findings suggest that psychological treatments have empirical support for addressing a wide range of psychological problems in these developmental stages. The degree of empirical support ranges from low to high depending on the phenomenon analyzed. The review suggests unequal progress in the different fields of intervention. CONCLUSIONS: From this update, psychologists will be able to make informed decisions when implementing those empirically supported treatments to address the problems that occur in childhood and adolescence.

Measuring entrepreneurship in adolescents at school: New psychometric evidence on the BEPE-A.

The economic situation worldwide demands individuals with entrepreneurial skills and aptitudes. The adolescence stage is a critical period in which these abilities could be developed and the school is a relevant setting for this purpose. To this end, instruments that allow assessing enterprising abilities are needed. Nonetheless, there remains a lack of instruments with adequate evidence of validity. The purpose of this study was, thus, to analyze the psychometric properties of the Battery for the Assessment of the Enterprising Personality-Adaptive (BEPE-A). The sample included a total of 1105 participants (men = 528; 47.4%) with an age range from 12 to 19 years (M = 15.23 years; SD = 4.40). The BEPE-A and the Entrepreneurial Attitudes Scale for Students (EASS) were used in the study. The EFA, conducted in a subsample of 512 participants, revealed that each of the subscales of the BEPE-A were basically unidimensional. The CFA, conducted in a second subsample of 593 participants, showed that a bifactor model best fit the BEPE-A structure. In addition, measurement invariance was found both by gender and age. The BEPE-A was positively associated with other measures of entrepreneurship. Results found in the study contribute valuable information about new evidences of a battery that allows screening for entrepreneurship in a critical developmental period such as adolescence, and in a relevant setting like school.

Schizotypy: The Way Ahead.

BACKGROUND: Empirical evidence suggests that schizotypy is a useful construct for analyzing and understanding psychotic disorders. However, several issues remain to be resolved. METHOD: This selective, critical review, addresses some questions and limitations, and discusses future directions of work. RESULTS: First, we present a conceptual outline and discuss the evidence from translational and interdisciplinary studies on schizotypy. Next, we examine and discuss newer analytical and methodological approaches, including network and machine learning approaches. We also discuss newer psychometric identification approaches, such as those using biobehavioral and ambulatory assessment. Next, we review recent cross-cultural studies in schizotypy research. Finally, we identify new challenges and directions and draw conclusions. CONCLUSIONS: This selective, critical review suggests that new methods can contribute to the construction of a solid scientific model of schizotypy as a risk construct.

Attitudes towards Violence in Adolescents and Youth Intimate Partner Relationships: Validation of the Spanish Version of the EAV.

The main purpose of the present study was to analyze the psychometric properties of the Attitudes Scale Towards Violence (Escala de Actitudes hacia la Violencia, EAV) in adolescents. The EAV is a questionnaire devoted to assess attitudes towards violence. Additionally, the relationship between EAV and violence manifestations and depressive symptoms was analyzed. The final sample comprised a total of 1248 students in a cross-sectional survey. The EAV, the Modified Conflict Tactics Scale (M-CTS), and the Reynolds Adolescent Depression Scale (RADS) were used. The analysis of the internal structure of the EAV yielded a two-factor structure as the most adequate. The EAV scores showed measurement invariance across gender and age. The McDonald's Omega was 0.862 and 0.872 for the two hypothesized factors. Furthermore, self-reported attitudes towards violence were associated with violence manifestations both as a victim and as a perpetrator and depressive symptoms. These results support that the EAV is a brief and easy tool to assess self-reported violence attitudes in intimate partner relationships in adolescents from the general population. The assessment of these attitudes, and its associations with violence and depressive manifestations, may help us to enhance the possibility of an early identification of adolescents potentially at risk for suffering violence as a victim or as a perpetrator.

Relationship between substance use and schizotypal traits in school-aged adolescents. / Relación entre consumo de sustancias y rasgos esquizotípicos en adolescentes escolarizados.

GOAL: The main goal of the present study was to analyze the relationship between substance use (tobacco, alcohol, cannabis) and schizotypal traits in a representative sample of school-aged adolescents from the general population. METHOD: cross-sectional, descriptive survey 1,588 students (M = 16.13 years, SD = 1.36), 739 male (46.5%), selected by random stratified cluster sampling, participated in the study. The instruments administered were the Oviedo Questionnaire for Schizotypy Assessment, the Modified Substance Use Questionnaire, the Strengths and Difficulties Questionnaire, the Penn Matrix Reasoning Test, the Family Affluence Scale-II, and the Oviedo Infrequency Scale. RESULTS: Controlling for the effects of multiple covariates (gender, age, IQ, socio-economic level, psychopathology and consumption), the results showed that compared with non-users, alcohol drinkers reported higher average scores in the Social Disorganization dimension. Cigarette smokers, differentiated by frequency, reported higher average scores in the Anhedonia and Social Disorganization dimensions than non-smokers. No statistically significant differences between users and non-users of cannabis were found in terms of schizotypal traits. CONCLUSION: controlling for the effects of multiple covariates, adolescents who use tobacco and alcohol reported higher scores - depending on frequency of use - in schizotypal traits. Future studies should continue to analyze the role of substance use in individuals at risk of psychosis and determine its role in the transition to serious mental disorders using new methodologies such as ambulatory assessment.

Objetivo: analizar la posible relación entre el consumo de sustancias psicoactivas (en concreto, tabaco, alcohol y cannabis) y los rasgos esquizotípicos en una muestra representativa de adolescentes escolarizados de la población general.  Método: diseño transversal descriptivo tipo encuesta. La muestra se compuso por 1.588 estudiantes (M = 16,13 años; DT = 1,36; 739 varones, 46,5%), seleccionados mediante muestreo aleatorio estratificado por conglomerados. Los instrumentos administrados fueron el Cuestionario Oviedo para la Evaluación de la Esquizotipia, el Cuestionario de Consumo de Sustancias Modificado, el Cuestionario de Capacidades y Dificultades, el Penn Matrix Reasoning Test, la Family Affluence Scale-II y la Escala Oviedo de Infrecuencia de Respuesta. Resultados: una vez controlado el efecto de múltiples covariables (género, edad, cociente intelectual, nivel socio-económico, psicopatología previa y consumo de sustancias), los consumidores de alcohol comparados con los no consumidores, informaron de mayores puntuaciones medias en la dimensión Desorganización Social. Los consumidores de tabaco comparados con los no consumidores, informaron de mayores puntuaciones medias en las dimensiones de esquizotipia de Anhedonia y Desorganización Social. Con respecto al consumo de cannabis, no se hallaron diferencias estadísticamente significativas entre consumidores y no consumidores en las dimensiones esquizotípicas. Conclusiones: controlando el efecto de múltiples variables de confundido, los adolescentes consumidores de tabaco y alcohol ­según su frecuencia­ informaron de mayores puntuaciones en rasgos esquizotípicos. Futuros estudios podrían continuar analizando el papel del consumo de sustancias en la aparición de trastornos mentales, como la psicosis, mediante nuevas metodologías como la evaluación ambulatoria.

Neurocognitive Functioning in Adolescents at Risk for Suicidal Behaviors.

Today, little is still known about the neurocognitive functioning of the individual at risk for suicide in a relevant developmental stage like adolescence. Thus, the main goal of the present work was to analyze the neurocognitive performance of adolescents at high risk for suicide. A total of 1509 adolescents from a stratified random cluster sampling were selected. Adolescents at risk for suicidal behaviors included 83 participants. A comparison group of 83 participants matched by age and gender was also randomly selected from the sample. The Paykel Suicide Scale (PSS) and the University of Pennsylvania Computerized Neurocognitive Battery for children (included 14 tasks assessing five neurobehavioral domains: executive functions, episodic memory, complex cognition, social cognition, and sensorimotor speed) were used. Adolescents at risk for suicide revealed statistically significant impairments across different neurocognitive domains including complex cognition, episodic memory and social cognition. No significant differences were found for Sensorimotor and Executive Function domains. Results found in the present study contribute relevant information about the nature of the neurocognitive impairments associated with suicide and add information in order to deeper comprehend the tentative etiology of suicide thoughts and attempts in adolescents with the aim to establish preventive treatments.

Identifying extended psychosis phenotypes at school: Associations with socio-emotional adjustment, academic, and neurocognitive outcomes.

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 reality distortion experiences, and high psychosis liability. The high-risk latent groups scored significantly higher on mental health difficulties, and negative affect, and lower on positive affect and well-being, compared to the two non-risk groups. Moreover, these high-risk groups had a significantly higher number of failed academic subjects compared to the non-risk groups. In addition, no statistically significant differences in efficiency performance were found in the neurocognitive domains across the four latent profiles. This study allows us to improve the early identification of adolescents at risk of serious mental disorder in school settings in order to prevent the incidence and burden associated with these kinds of mental health problems.

SENTIA: An Adolescent Suicidal Behavior Assessment Scale.

BACKGROUND: The main objective of this work was to design and validate a new measuring instrument, called SENTIA, for assessing suicidal behavior in Spanish adolescents. METHOD: a total of 1790 randomly selected students participated in the survey. The average age was 15.70 ( SD =1.26), 53.7% of the sample were girls. RESULTS: The results of exploratory factor analyses suggested that the dimensional structure that best explained the SENTIA scores was a bifactor model, specified in a general suicidal behavioral factor plus three specific factors (Ideation, Communication, and Act/Planning). SENTIA scores demonstrated adequate levels of reliability. None of the SENTIA items showed differential functioning by gender. SENTIA scores were positively associated with suicidal ideation, symptoms of depression, emotional and behavioral problems, and psychotic-like experiences. CONCLUSIONS: SENTIA is a useful, easy, brief measuring instrument that has been specifically constructed and validated for the assessment of suicidal behavior in Spanish adolescents. As a screening tool, SENTIA can help the analysis, evaluation, understanding, and intervention in a the major socio-health problem that is suicide.

Suicidal behaviour in adolescents: A network analysis. / Conducta suicida en adolescentes: un análisis de redes.

OBJECTIVE: Suicidal behaviour has not yet been analysed from a network approach in adolescent samples. It is imperative to incorporate new psychological models to understand suicidal behaviour from a different perspective. The main objective of this work was twofold: a) to examine suicidal behaviour through network analysis and b) to estimate the psychological network between suicidal behaviour and protective and risk factors in school-age adolescents. METHOD: Participants were 443 students (M = 14.3 years; SD = 0.53; 51.2% female) selected incidentally from different schools. Different instruments were administered to assess suicidal behaviour, emotional and behavioural difficulties, prosocial behaviour, subjective well-being, emotional intelligence, self-esteem, depressive symptomatology, empathy, positive and negative affect, and emotional regulation. RESULTS: The resulting network of suicidal behaviour was strongly interconnected. The most central node in terms of strength and expected influence was «Consider taking your own life¼. In the estimated psychological network of suicidal behaviour and risk and protective factors, the nodes with the highest strength were depressive symptomatology, positive affect, and empathic concern. The most influential nodes were those related to emotional intelligence abilities. Suicidal behaviour was positively connected to depression symptoms and negative affect, and negatively connected to self-esteem and positive affect. The results of the stability analysis indicated that the networks were accurately estimated. CONCLUSIONS: Suicidal behaviour can be conceptualized as a dynamic, complex system of cognitive, emotional, and affective characteristics. The new psychopathological and psychometric models allow us to analyse and understand human behaviour and mental health problems from a new perspective, suggesting new forms of conceptualization, evaluation, intervention, and prevention.

Emotional and behavioural difficulties and prosocial behaviour in adolescents: A latent profile analysis. / Dificultades emocionales y conductuales y comportamiento prosocial en adolescentes: un análisis de perfiles latentes.

INTRODUCTION: The purpose of this study was to identify homogenous subgroups of adolescents with emotional and behavioural difficulties using latent profile analysis. The relationship between the latent profile classes and socio-emotional and school adjustment was also analysed. MATERIALS AND METHODS: A total of 1,506 students, 667 men (44.3%) were selected by random cluster sampling. The mean age was 16.15 years (SD=1.36). The instruments used were the Strengths and Difficulties Questionnaire, the Personal Wellbeing Index-School Version, The 10-item Positive and Negative Affect Schedule for Children, the Prodromal Questionnaire Brief, the Paykel Suicide Scale, the Cyberbullying-Brief Questionnaire, the Penn Matrix Reasoning Test, and the school performance assessment. RESULTS: A total of 7.7% of adolescents obtained risk scores for mental health difficulties. We identified 3 mental health subgroups named: Low risk, Externalizing, and Internalizing. These 3 latent classes demonstrated a differential pattern in terms of socio-emotional adjustment and academic performance. CONCLUSIONS: To identify and validate risk groups of youths for emotional and behavioural problems allows implementing measures to promote emotional well-being and prevent mental health problems. Future studies should continue to analyse young people with emotional and behavioural problems longitudinally and to incorporate new forms of assessment and intervention.
