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.

Conclusiones: estos hallazgos demuestran que diferentesalteraciones neurocognitivas pueden manifestarse en adolescentes con altoriesgo psicométrico de presentar problemas de salud mental antes de laaparición de dificultades psicológicas más graves.

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.

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.

New Evidences about Subjective Well-Being in Adolescence and Its Links with Neurocognitive Performance.

The main purpose of the present work was to study the neurocognitive endophenotypes of adolescents at risk for low personal wellbeing. The sample included a total of 1588 adolescents from stratified random cluster sampling; derived from this sample, a group of high-risk (n = 84) and a control group (n = 84) were selected. The personal well-being index-school children (PWI-SC), 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), and the strengths and difficulties questionnaire (SDQ) were used. Adolescents with low personal wellbeing showed statistically significant impairments across the different neurocognitive domains. In particular, adolescents at risk showed lower accuracy scores on executive function and complex cognition and lower speed scores on episodic memory, complex cognition and social cognition scores. The results of the present study contribute relevant information about the nature of neurocognitive impairments associated with subjective wellbeing and allow implementing preventive treatments.

Ideación suicida en una muestra representativa de adolescentes españoles / Suicidal ideation in a community-derived sample of Spanish adolescents

Introducción. El suicidio es un problema sociosanitario de primer orden. El propósito de este estudio fue analizar la ideación suicida en una muestra representativa de adolescentes españoles. Concretamente, se examinó las tasas de prevalencia, se validó la Escala Paykel de Ideación Suicida (Paykel Suicide Scale, PSS) y se analizó el ajuste socioemocional de aquellos adolescentes con ideación suicida. Material y métodos. La muestra la formaron 1.664 participantes (M=16,12 años; DT=1,36; rango 14-19 años) seleccionados mediante muestreo estratificado por conglomerados. Los instrumentos empleados fueron la PSS, el Strengths and Difficulties Questionnaire, el Personal Wellbeing Index-School Children y la Escala Oviedo de Infrecuencia de Respuesta. Resultados. El 4,1% de la muestra informó haber intentado quitarse la vida en el último año. Se encontraron diferencias estadísticamente significativas en las puntuaciones medias de la PSS en función del género pero no en función de la edad. El modelo unidimensional de la PSS presentó excelentes índices de bondad de ajuste y se mostró invariante en función del género. La fiabilidad de las puntuaciones de la PSS, estimada con el alfa ordinal, fue de 0,93. Los participantes con ideación suicida informaron de un peor estado de salud mental y menor satisfacción con la vida respecto al grupo de comparación. Conclusiones. La ideación suicida se encuentra presente en población adolescente y se asocia a un peor bienestar emocional subjetivo y a mayores problemas emocionales y comportamentales. La PSS parece mostrar un adecuado comportamiento psicométrico para evaluar la ideación suicida en adolescentes. Estos resultados tienen claras implicaciones, tanto a nivel sanitario como educativo, de cara a mejorar la promoción del bienestar emocional y la prevención de los problemas psicológicos y psiquiátricos en este sector de la población

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 Personal Wellbeing Index-School Children, and the Oviedo Infrequency Scale. Results. The results showed that 4.1% of the sample indicated that they had tried to commit suicide in the previous year. Statistically significant differences were found according to gender but not according to age in the PSS mean scores. The analysis of the internal structure of the PSS showed that the one-dimensional model presented excellent goodness of fit indexes. This model showed measurement invariance across gender. The reliability of the scores, estimated with ordinal alpha, was 0.93. Participants who reported suicide ideation showed poorer mental health status and lower life satisfaction compared to the non-suicide ideation group. Conclusions. Suicidal ideation is present during adolescence and is associated with poor subjective well-being and increased emotional and behavioural problems. PSS seems to show adequate psychometric behaviour to assess suicidal ideation in adolescents. These findings have clear implications, both in health and education systems, to improve the promotion of emotional well-being and prevention of psychological and psychiatric problems in this sector of the population

Mental health difficulties in children and adolescents: The study of the SDQ in the Spanish National Health Survey 2011-2012.

The Strengths and Difficulties Questionnaire (SDQ) is a well-known measuring instrument widely used for the assessment of mental health in children and adolescents. Relatively few studies have analysed the factor structure, the measurement invariance, and the internal consistency, including the information function of the SDQ in its parent version. The study included a large sample (N = 3828) from the Spanish National Survey (2016 were male; 52.7%). Mean age was 9.13 (SD = 3.21) with ages ranging from 4 to 14. The level of internal consistency of the scores for the Total difficulties score was 0.84, ranging between 0.75 and 0.78 for the SDQ subscales. Results from the confirmatory factor analysis showed a five-factor model as the most appropriate. Nonetheless, the fit indices were inadequate and different modifications were needed. The hypothesis of measurement invariance of the SDQ scores across gender and educational level was supported. The present study allows us to affirm that the SDQ, parent's version form, appears to be an adequate tool for the screening of emotional and behavioural problems for children and adolescents. Future research should analyse the SDQ at cross-cultural level, incorporating novel psychometric frameworks and new mental health classifications.

Screening for depressive symptoms in adolescents at school: New validity evidences on the short form of the Reynolds Depression Scale.

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 level of internal consistency of the RADS-SF Total score by means of Ordinal alpha was .89. Results from CFAs showed that the one-dimensional model displayed appropriate goodness of-fit indices with CFI value over .95, and RMSEA value under .08. In addition, the results support the strong measurement invariance of the RADS-SF scores across gender and age. When latent means were compared, statistically significant differences were found by gender and age. Females scored 0.347 over than males in Depression latent variable, whereas older adolescents scored 0.111 higher than the younger group. In addition, the RADS-SF score was associated with the RADS scores. The results suggest that the RADS-SF could be used as an efficient screening test to assess self-reported depressive symptoms in adolescents from the general population.

New evidence of factor structure and measurement invariance of the SDQ across five European nations.

The main purpose of the present study was to analyse the internal structure and to test the measurement invariance of the Strengths and Difficulties Questionnaire (SDQ), self-reported version, in five European countries. The sample consisted of 3012 adolescents aged between 12 and 17 years (M = 14.20; SD = 0.83). The five-factor model (with correlated errors added), and the five-factor model (with correlated errors added) with the reverse-worded items allowed to cross-load on the Prosocial subscale, displayed adequate goodness of-fit indices. Multi-group confirmatory factor analysis showed that the five-factor model (with correlated errors added) had partial strong measurement invariance by countries. A total of 11 of the 25 items were non-invariant across samples. The level of internal consistency of the Total difficulties score was 0.84, ranging between 0.69 and 0.78 for the SDQ subscales. The findings indicate that the SDQ's subscales need to be modified in various ways for screening emotional and behavioural problems in the five European countries that were analysed.
