RESUMO
BACKGROUND: There is a need for a measure that can be used across countries and cultures to advance cross-cultural research about internalizing mental health symptoms in children and adolescents. The Revised Children's Anxiety and Depression Scale (RCADS) is a potential candidate, but no study has examined whether its scales are measured similarly in youth populations from different countries. METHODS: In this study, we use confirmatory factor analysis (CFA) and multi-group CFA to examine the cross-cultural properties of a short and free to use 30-item version of RCADS that assesses social, generalized, panic, and separation anxiety alongside depression and obsessive-compulsive symptoms. We tested the factor structure of RCADS in children and adolescents from Chile, Spain, and Sweden, recruited using different research designs (i.e., school-based studies and an anonymous web survey), and whether the factor structure showed measurement invariance across the three countries. RESULTS: The proposed factor structure of RCADS showed good model/data fit in all three countries and was superior to a unidimensional model in which correlations among scale items were explained by a single broad internalizing factor. Each RCADS subscale showed adequate to excellent internal consistency in all three countries and multi-group CFA supported scalar invariance across the three countries. LIMITATIONS: No clinical sample was included. CONCLUSIONS: This study provides an important first step in supporting the use of RCADS in cross-cultural research on depression, anxiety and obsessive-compulsive symptoms in children and adolescents, but more work on validity aspects of the scale across cultures is needed.

BACKGROUND: Symptoms of depression and anxiety are common in children with obsessive-compulsive disorder (OCD) and associated with more severe OCD, greater impairment, and worse treatment outcome. Beyond twin studies showing that genetic factors contribute to the high co-occurrence, few studies have examined how OCD, depression, and anxiety are linked in youth, and current studies often fail to account for OCD and anxiety heterogeneity. METHODS: Network analysis was used to investigate how OCD were linked to depression and anxiety in multinational youth diagnosed with OCD (total n = 419) and in school-recruited, community-based samples of youth (total n = 2 991). RESULTS: Initial results aligned with earlier work showing that severity of obsession-related symptoms are important in linking OCD to depression in youth with OCD. However, when symptom content of OCD (e.g., washing, ordering) was fully taken into account and when measures of anxiety were included, specific OCD symptom dimensions (primarily obsessing and doubting/checking) were linked to specific anxiety dimensions (primarily panic and generalized anxiety) which in turn were linked to depression. These results were replicated in three separate community-based samples from Chile, Italy, and Spain using different measures of anxiety and depression. LIMITATIONS: Cross-sectional data were analyzed which precludes causal inference. Self-report measures were used. CONCLUSIONS: Youth with OCD with symptoms related to doubting/checking and obsessing should be carefully assessed for symptoms of panic and generalized anxiety. Non-responders to standard OCD treatment may benefit from interventions targeting panic and generalized anxiety, but more research is needed to test this hypothesis.

Abstract Attention deficit hyperactivity disorder (ADHD) is considered to be one of the most common disorders during children and adolescents' neurodevelopment. Given how much the individuals executive functions are affected, the objective of the present study was to verify the validity of the Neuropsychological Assessment of Executive Functions battery for Children (ENFEN for its acronym in Spanish) as a predictor in the diagnosis of ADHD. The sample consisted of 175 participants from southeast Spain of both sexes aged between 6 and 12 (clinical M=8.39, SD=1.87, and control M=8.78, SD=1.91). The clinical group was composed of 89 (79.50%) males and 23 (20.50%) females, and the control group consisted of 37 (58.70%) males and 26 (41.30%) females. ENFEN is an individual applications battery that allows the executive functions to be globally evaluated using a wide range of elements. We followed a non-experimental research design for this comparative descriptive study. The results indicate that the phonological fluency, colour naming path, and interference scales are closely associated with the diagnosis of ADHD as they provide data on elements including inhibition, mental flexibility, sustained and selective attention, verbal fluency, and working memory. In general, this study supports the usefulness and validity of the ENFEN battery as a tool to clinically diagnose ADHD.
Resumen El trastorno por déficit de atención en hiperactividad (TDAH) es uno de los trastornos más frecuentes en el neurodesarrollo de niños y adolescentes. Las personas que lo padecen se caracterizan por presentar dificultades en los procesos de atención sostenida, ser muy activos y tener un deficiente control de sus impulsos. Pese a su elevada prevalencia y la existencia de diversas pruebas utilizadas para su diagnóstico, se conocen pocos datos sobre la utilidad y validez diagnóstica de estas herramientas. Dada la gran afectación que estos sujetos presentan en las funciones ejecutivas, el objetivo de este estudio es comprobar la utilidad y validez de la batería de Evaluación Neuropsicológica de las Funciones Ejecutivas en Niños (ENFEN), como predictora herramienta de apoyo al diagnóstico de TDAH. La muestra de estudio estuvo compuesta por 175 participantes de ambos sexos, con edades comprendidas entre los 6 y 12 años (grupo clínico M=8.39, SD=1.87 y grupo control M=8.78, SD=1.91). El grupo clínico estaba compuesto por 89 (79.50%) hombres y 23 (20,50%) mujeres, y el grupo de control por 37 (58,70%) hombres y 26 (41,30%) mujeres. ENFEN es una batería de aplicación individual, compuesta por varias subpruebas que requieren el empleo de funciones ejecutivas para resolver los elementos que las componen. Se siguió un diseño no-experimental para llevar a cabo un estudio descriptivo comparativo. Los resultados señalaron que las escalas Fluidez Fonológica, Sendero Color e Interferencia que requieren en mayor medida inhibición, flexibilidad mental, atención sostenida y selectiva, fluidez verbal y memoria de trabajo, entre otras aptitudes cognitivas, son las que mejor se asocian al diagnóstico de TDAH. En general, este estudio apoya la utilidad y validez de la prueba ENFEN como herramienta para el diagnóstico clínico del TDAH.

In recent years, there has been a considerable increase in the development of assessment tools for obsessive-compulsive symptomatology in children and adolescents. The Obsessive Compulsive Inventory-Child Version (OCI-CV) is a well-established assessment self-report, with special interest for the assessment of dimensions of Obsessive Compulsive Disorder (OCD). This instrument has shown to be useful for clinical and non-clinical populations in two languages (English and European Spanish). Thus, the aim of this study was to analyze the psychometric properties of the OCI-CV in a Chilean community sample. The sample consisted of 816 children and adolescents with a mean age of 14.54 years (SD = 2.21; range = 10-18 years). Factor structure, internal consistency, test-retest reliability, convergent/divergent validity, and gender/age differences were examined. Confirmatory factor analysis showed a 6-factor structure (Doubting/Checking, Obsessing, Hoarding, Washing, Ordering, and Neutralizing) with one second-order factor. Good estimates of reliability (including internal consistency and test-retest), evidence supporting the validity, and small age and gender differences (higher levels of OCD symptomatology among older participants and women, respectively) are found. The OCI-CV is also an adequate scale for the assessment of obsessions and compulsions in a general population of Chilean children and adolescents.

BACKGROUND: Obesity is a public health problem of alarming proportions, including among the university population in Latin America. The purpose of this study was to determine the relation between the self-reported body mass index and the associated drug use and health-risk behaviors. METHODS: We performed a cross-sectional, descriptive study of 3,311 Chilean university students (17-24 years). The variables weight, height, frequency of physical activity, diet quality index, and drug use were evaluated by way of a self-report questionnaire. RESULTS: 16.7% of students were overweight and 2.1% were obese. Higher rates of overweight and obesity were observed in the men compared to women. There was a significant but moderate association between self-perceived obesity and being men and higher age, and just low with greater use of analgesics and tranquilizers with or without a prescription. CONCLUSIONS: The punctual prevalence rates of self-reported obesity, in this sample, are consistent with other Latin American studies. The risk behaviors associated with perceived obesity in terms of gender, particularly the different pattern of drug use, highlight the importance of considering gender when designing strategies to promote health in a university setting.

BACKGROUND: Happiness has been associated with a range of favourable health outcomes through two pathways: its relationship with favourable biological responses to stress and with healthy lifestyles and prudent health behaviours. There are a substantial number of cross-cultural studies about happiness, but none of them has studied the association of happiness with perceived stress and health behaviours in Latin American samples. Therefore, the aim of this study was to examine the association between general happiness and these variables in a Latin American sample. METHODS: We conducted a survey to examine the status of 3461 students aged between 17 and 24 years old (mean age = 19.89; SD = 1.73) who attended University of Santiago de Chile during 2009. The healthy behaviours indexes assessed were the frequency of daily physical exercise, fruits/vegetables intake, breakfast and lunch intake, smoking, alcohol and other drugs consumption. We also included the assessment of perceived stress and Body Mass Index. All of them were evaluated using a self-report questionnaire. RESULTS: The univariate and multivariate binary logistic regression analyses showed that being female and younger was related to a higher happiness, as well as that people self-reporting daily physical activity, having lunch and fruits and vegetables each day had a higher likelihood (OR between 1.33 and 1.40) of being classified as "very happy". Those who informed felt stressed in normal circumstances and during tests situations showed a lower likelihood (0.73 and 0.82, respectively) of being considered "very happy". Regarding drug consumption, taking tranquilizers under prescription was negative related to "subjective happiness" (OR = 0.62), whereas smoking was positive associated (OR = 1.20). CONCLUSIONS: The findings of this study mainly support the relationship between happiness and health outcomes through the two pathways previously mentioned. They also underscore the importance of that some healthy behaviours and person's cognitive appraisal of stress are integrated into their lifestyle for college students. Additionally, highlight the importance of taking into account these variables in the design of strategies to promote health education in university setting.
