RESUMO

Resumen La adultez emergente es un nuevo periodo evolutivo, que abarca de los 18 a los 29 años. El instrumento más utilizado para evaluarla es el Inventario de Dimensiones de Adultez Emergente (IDEA). El objetivo general del estudio fue evaluar la pertinencia cultural y las características psicométricas del IDEA y de 25 ítems culturales/émicos en una muestra de 589 de universitarios chilenos. Análisis factoriales exploratorios demostraron que el IDEA tiene una estructura similar a la señalada por otro estudio chileno, y los ítems culturales conforman una estructura de tres factores. El análisis factorial confirmatorio arrojó un modelo unifactorial de seis indicadores, tres contienen 21 ítems originales del IDEA, y tres conservan 24 ítems culturales formando un solo instrumento, denominado IDEA - extendido, con propiedades psicométricas adecuadas. Este instrumento caracteriza la adultez emergente como una sola etapa de vida, que contiene aspectos éticos y émicos, dando un panorama integrado de sus características.

Abstract Emerging adulthood is a new evolutionary period ranging from 18 to 29 years. The most used instrument to evaluate it is the Inventory of the Dimensions of Emerging Adulthood (IDEA). The general objective of the study was to evaluate the cultural relevance and psychometric characteristics of the IDEA and 25 cultural/ emic items in a sample of 589 Chilean university students. Exploratory factorial analysis showed that the IDEA has a similar structure to one indicated by another Chilean study, and the cultural items form a three-factor structure. Confirmatory factorial analysis threw a unifactorial model of six indicators, three of them contain 21 original items of the IDEA, and three conserve 24 cultural items forming a single instrument, called extended - IDEA, with adequate psychometric properties. This instrument characterizes the emerging adulthood as a single stage of life, which contains ethical and emic aspects, giving an integrated view of its characteristics.

RESUMO

The Schizotypal Personality Questionnaire-Brief (SPQ-B) is a commonly-used tool for measuring schizotypal personality traits and due to its wide application, its cross-cultural validity is of interest. Previous studies suggest that the SPQ-B either has a three- or four-factor structure, but the majority of studies have been conducted in Western contexts and little is known about the psychometric properties of the scale in other populations. In this study factorial invariance testing across three cultural contexts-Australia, China and Chile was conducted. In total, 729 young adults (Mean age = 23.99 years, SD = 9.87 years) participated. Invariance testing did not support the four-factor model across three countries. Confirmatory Factor Analyses revealed that neither the four- nor three-factor model had strong fit in any of the settings. However, in comparison with other competing models, the four-factor model showed the best for the Australian sample, while the three-factor model was the most reasonable for both Chinese and Chilean samples. The reliability of the SPQ-B scores, estimated with Omega, ranged from 0.86 to 0.91. These findings suggest that the SPQ-B factors are not consistent across different cultural groups. We suggest that these differences could be attributed to potential confounding cultural and translation issues.

RESUMO

La Adultez Emergente es un periodo de vida entre los 18 y 29 años, culturalmente construido y no de carácter universal. Ante la escasez de estudios en esta etapa en Chile, el objetivo de esta investigación fue caracterizar la Adultez Emergente, y determinar sus rasgos más relevantes en universitarios chilenos, a través de una aproximación cualitativa, desde los protagonistas. Seis grupos focales conformados por 60 universitarios a nivel nacional analizaron los ítems del Inventario de Dimensiones de Adultez Emergente o discutieron sus creencias sobre tres áreas definidas a priori: Identidad y Autoconcepto, Relación con los padres y salida del hogar, y Amor y sexualidad. Se evidencia la presencia de la Adultez Emergente en universitarios, pues las características centrales de la teoría están presentes en este grupo, y se obtiene evidencia de aspectos de carácter cultural propios de los universitarios chilenos, relacionados a la importancia de los vínculos familiares y sociales.

Emerging Adulthood is a period of life between 18 and 29 years old, culturally constructed and not universal. Given the paucity of studies about this developmental stage in Chile, the objective of this research was to characterize Emerging Adulthood and determine its most important features in Chilean university students using a qualitative approach, focused at the protagonists themselves. Six focus groups formed by 60 university students revised the items of the Inventory of Dimensions of Emerging Adulthood (IDEA) or discussed their beliefs about three areas defined a priori: Identity and self-concept, Relationship with parents and leaving home, and Love and sexuality. The presence of the Emerging Adulthood stage in university students is evident since its central features are present in this group; also there is evidence of others aspects that belong to cultural characteristics of the own Chilean university students which are related to the importance given to the family and social relationships.

RESUMO

Resumen: Este estudio determinó los puntajes de corte de las Escalas abreviadas de Depresión, Ansiedad y Estrés (DASS-21) para detectar jóvenes en riesgo de problemas de salud mental. Se utilizó una muestra de 393 jóvenes no consultantes y una muestra clínica de 77 jóvenes consultantes en fase inicial de tratamiento. La presencia de sintomatologia fue utilizada como gold standard para determinar puntajes de corte entre jóvenes de población general asintomáticos y consultantes con sintomatologia clínica. Mediante análisis de curvas ROC se examinó la capacidad de discriminación de cada escala, y a través de análisis de sensibilidad y especificidad se determinaron puntajes de corte. El área bajo la curva para cada una de las escalas del DASS-21 fue mayor a 0.90. Para la escala de Depresión, se seleccionó un punto de corte de 6 (>5), con una sensibilidad de 88,46 y especificidad de 86,77. Para la escala de Ansiedad, el punto de corte correspondió a 5 (>4), con sensibilidad de 87,50 y especificidad de 83,38. En la escala Estrés, se seleccionó un punto de corte de 6 (>5), con una sensibilidad de 81,48 y especificidad de 71,36. Las escalas de Depresión, Ansiedad y Estrés (DASS-21) demostraron una adecuada utilidad como instrumento de tamizaje.

Abstract: The short version of Depression, Anxiety and Stress Scales (DASS-21; Lovibond y Lovibond, 1995) has been shown to have appropriate psychometric properties among Chilean adolescents and undergraduates. The current study was aimed at determining the cut-off scores of the Depression, Anxiety and Stress Scales (DASS-21) for screening Chilean youngsters at risk of mental health problems and requiring mental health treatment. The sample comprised 393 non-patients youngsters aged 15-24 and 77 youngsters at early stage of psychotherapy. The presence of symptoms was used as gold standard for estimating the cut-off betWeen non-symptomatic youngsters and symptomatic patients. Receiving Operating Characteristic (ROC) analyses allowed examining accuracy of each scale and sensitivity and specificity analysis was performed for determining the cut-off points. The area under the receiver operating characteristics curve (AUC) was higher than 0.9 for each scale of the DASS-21. The optimal cut-off score for the Depression scale was 6 and above, which resulted in sensitivity=88,46 and specificity=86,77, and a cut-off of 5 and above was optimal for the anxiety scale, with a sensitivity of 87,50 and specificity of 83,38.The Stress Scale had sensitivity of 81,48 and specificity of 71,36 at the optimal cut-off score of 6 and above. These findings suggest that the DASS-21 performs adequately as a screening tool to identify Chilean young people at risk of mental health problems.

RESUMO

Este estudio tuvo por objetivo determinar las propiedades psicométricas del Five Facet Mindfulness Questionnaire (FFMQ) en estudiantes universitarios de la ciudad de Temuco en Chile (n = 399). El FFMQ es una prueba de autoreporte compuesta por 39 ítems, que mide la tendencia general a proceder con Atención Plena a partir de cinco habilidades: Observación, Descripción, Actuar con Conciencia, Ausencia de Juicio y Ausencia de Reactividad. El diseño es descriptivo correlacional, de grupo único. Los resultados muestran una confiabilidad adecuada y la asociación de Atención Plena con dimensiones de personalidad del Modelo de los Cinco Factores de Costa y McCrae, con la Autoactualización de las teorías humanistas y una relación inversa con estados emocionales negativos de depresión, ansiedad y estrés. Los análisis muestran que la versión nacional del FFMQ posee adecuadas propiedades psicométricas para ser utilizado en estudiantes universitarios chilenos y permite discriminar entre meditadores y no meditadores.

This study aimed to determine the psychometric properties of the Five Facet Mindfulness Questionnaire (FFMQ) in university students from the city of Temuco, Chile (n = 399). The FFMQ is a self-report test consisting of 39 items, which measures the general tendency to proceed with Mindfulness by using five skills: Observation, Description, Acting with Awareness, Non-judging of inner experience and Non-reactivity to inner experience. The design is descriptive correlational of unique group. The results show adequate reliability and Mindfulness association with personality dimensions of the Five Factor Model of Costa and McCrae, with the Self-Actualization of humanistic theories and an inverse relation to negative emotional states of depression, anxiety and stress. Analyzes show that the Chilean version of FFMQ has adequate psychometric properties for use in Chilean university students and discriminates between meditators and non-meditators.

RESUMO

BACKGROUND: The increase in university population in Chile has also increased the number of students presenting mental health disorders. AIM: To determine the frequency of mental health problems and its association with other relevant variables among students of a regional university in Chile. MATERIAL AND METHODS: A sample of 484 students aged 18 to 28 years (45% males) were assessed once using a battery of tests designed to detect mental health problems. The instruments used were Derogates SCL-90-R, Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI-II), Depression, Anxiety and Stress Scales (DASS-21) and a social-demographic questionnaire. RESULTS: Fifteen percent of the sample presented high levels of mental health symptoms, determined according to the cut-off points of Beck inventories. This symptomatic group, which also showed high levels of stress, was composed mostly of freshmen and women. There was a significant association between symptoms and socio-demographic variables such as living in rural areas, ethnicity and socioeconomic status, a higher need for psychological and psychiatric care and a lower number of extracurricular activities. CONCLUSIONS: The knowledge of mental health problems among university students will allow to generate strategies for mental health prevention, promotion and treatment.

RESUMO

Currently, the consumption of alcohol and drugs is a major public health problem worldwide due to its high social and economic impact. In Chile, the highest prevalence and greatest drug consumption rates occur in young people aged 19 to 25 years. Adolescence is the most vulnerable development stage for starting drug use. The latest study from CONACE (Chilean National Council for Drugs Control) in school population indicates that 15.1% of students report having used marijuana in the past year, while 33% admitted current use of tobacco and 36% of alcohol. Drug use among adolescents is exacerbated upon verification of its relationship with other risk behaviors as law transgressions, sexual promiscuity, teenage pregnancy and family difficulties. This situation has led various theorists to develop psychological assessment tools to specifically detect and evaluate drug use in adolescence. Among the instruments for psychological assessment, self-report measures have been the most widely used method to evaluate the use of alcohol and other drugs and their associated problems. One of the greatest strengths of self-report measures is that they can detect problems related to drugs in people who for various reasons would like to hide their status of substance abusers. The Minnesota Multiphasic Personality Inventory for Adolescents (MMPI-A) is one of the best self-report instruments for clinical assessment in adolescent population. The MMPI-A consists of 478 items with True and False response format and it has three scales that specifically detect substance abuse problems; they are: MacAndrew's Alcoholism Scale Revised (MAC-R, in Spanish MAC-A), Alcohol/Drug Problem Acknowledgement Scale (ACK, in Spanish RPAD) and Alcohol/Drug Problem Proneness Scale (PRO, in Spanish TPAD). In Chile, there is a MMPI-A version which has empirical studies that support its use with general population Chilean adolescents. These studies also highlight the usefulness that MAC, ACK and PRO scales could have to provide detailed information on specific features that would impact on the use of alcohol and drugs. The aim of this study was to examine the ability of the MMPI-A Chilean version to detect substance abuse problems in specific settings. Its objectives were: 1. to determine the applicability of MAC-R, ACK and PRO scales in different samples of Chilean adolescents, 2. to evaluate the ability of these scales to discriminate problematic substance use in adolescents with and without other clinical problems, and 3. to propose discriminative cut-off scores for the indicated scales. In order to accomplish these goals, we used a quantitative methods approach with a descriptive correlational design for three independent groups. The sample comprised 74 adolescents (44 males and 30 females) with clinical problems that had substance use, diagnosed according to the CONACE criteria for unproblematic consumption categories (occasional and habitual consumption) and DSM-IV criteria for problematic use (abuse and dependence). This group was named "clinical adolescents with consumption" (CCC). Using this group as reference, we selected two additional contrasting groups: a group of adolescents with clinical problems but without substance use called "clinical adolescents without consumption" (CSC; n=71), and a group of school adolescents from general population without substance consumption problems nor other psychopathological problems that would warrant clinical attention called "school-youngsters from general population" (EPG; n=74). The total sample (n=219) had an average age of 16.3 years (SD=1.3) and was collected in urban centers located in south-central Chile. Two instruments were used: The Minnesota Multiphasic Personality Inventory for Adolescents (MMPI-A), which provides the three scales for the assessment of substance abuse: the MAC-R scale is a revision of the MAC scale, originally developed by MacAndrew to distinguish alcoholic from non-alcoholic psychiatric outpatients; the other two scales were developed for the assessment of alcohol and other drugs problems among adolescents. Specifically, the ACK scale was a rationally constructed scale of 13 items with obvious content relating to alcohol or other drug use; while the PRO scale was a 36-item scale constructed empirically by selecting items with no-obvious content related to substance uses that discriminated between adolescents who were in treatment for substance abuse and normal adolescents, or adolescents in clinical treatment. In addition, the clinical MMPI-A scales were used as a supplementary measure. The second instrument was a semi-structured clinical interview based on two clinical guides called protocols A and B. Protocol A allows for doing a clinical interview with adolescents starting from two open-ended questions that inquire reasons for consultation and information on family structure and dynamics. It also checks symptoms in six areas including school, behavioral, emotional, physical, sexual and interpersonal symptoms. Behavioral symptoms include the checking out for consumption of alcohol and drugs. Those adolescents who respond positively to the consumption of alcohol and drugs must answer Protocol B. This is a clinical guide of ad hoc construction, based on the criteria used by the CONACE for the diagnosis of non-problematic use of substances and the DSM-IV criteria for diagnosis of drug abuse and dependence.

En la actualidad, el consumo de alcohol y drogas es uno de los mayores problemas de salud pública en el mundo, debido a su alto costo social y económico. En Chile, las prevalencias más altas y la mayor intensidad en el consumo de drogas se registran en los jóvenes de 19 a 25 años, siendo la adolescencia la etapa más vulnerable para el inicio del consumo de drogas. El último estudio del CONACE (Comisión Nacional de Control de Estupefacientes) en población escolar señala que 15.1% de los estudiantes chilenos declaran haber consumido marihuana en el último año, mientras que 33% reconoce un consumo actual de tabaco y 36% de alcohol. El consumo de drogas en adolescentes se agrava al comprobarse su relación con otras conductas de riesgo, lo que plantea la necesidad de desarrollar instrumentos de evaluación psicológica que consideren el consumo de drogas en la adolescencia de modo específico. Entre los instrumentos de evaluación psicológica, las medidas de autorreporte han sido el método más utilizado para evaluar el uso de alcohol y drogas, pues permiten detectar este problema en personas que por diferentes motivos desearían esconder su condición de abusadores de sustancias. Uno de los instrumentos de autorreporte es el Inventario Multifásico de la Personalidad de Minnesota para Adolescentes (MMPI-A) el cual posee tres escalas que evalúan el consumo de alcohol y drogas: Alcoholismo de MacAndrew Revisada (MAC-A; en inglés, MAC-R), Reconocimiento de Problemas con el Alcohol y/o Drogas (RPAD; en inglés, ACK) y Tendencia a Problemas con el Alcohol y/o Drogas (TPAD; en inglés, PRO). Aunque en Chile existe una versión en español de la prueba y estudios empíricos que respaldan su uso con adolescentes chilenos, no se había estudiado su funcionamiento con adolescentes consumidores de drogas, lo cual motivó el desarrollo de la presente investigación. Los objetivos del estudio fueron: 1. conocer el comportamiento de las escalas MAC-A, RPAD y TPAD en diferentes muestras de adolescentes chilenos, 2. evaluar la capacidad de estas escalas para discriminar el consumo problemático de sustancias en adolescentes con y sin otros problemas clínicos y 3. proponer puntajes de corte discriminativos para las escalas señaladas. La muestra está compuesta por 74 adolescentes (44 hombres y 30 mujeres) con problemas clínicos que presentaban consumo de sustancias, diagnosticado según los criterios del CONACE para las categorías de consumo no problemático (ocasional y habitual) y del DSM-IV para el consumo problemático (abuso y dependencia). Este grupo fue denominado adolescentes Clínicos Con Consumo (CCC). A partir de él se seleccionó a dos grupos de contrastación: un grupo de adolescentes consultantes por problemas clínicos pero sin consumo de sustancias, los cuales fueron denominados adolescentes Clínicos Sin Consumo (CSC) y un grupo de adolescentes escolarizados de población general sin problemas de consumo ni otros problemas psicopatológicos que ameritaran una consulta clínica, denominados adolescentes Escolares de Población General (EPG). Los principales resultados de este estudio muestran que el MMPI-A es capaz de discriminar a los adolescentes clínicos consumidores de drogas de los adolescentes clínicos sin consumo y de los escolares de población general. Las puntuaciones de las escalas clínicas en general son superiores en los dos grupos de procedencia clínica que en el grupo normal. Las escalas suplementarias, MAC-A, RPAD y TPAD, poseen una capacidad de discriminación muy alta; la mayor capacidad de discriminación de las tres escalas se logra al diferenciar entre los adolescentes del grupo CCC y los del grupo EPG en los dos sexos, siendo TPAD la que mejor discrimina. Además, cabe destacar la utilidad de MAC-A y RPAD para distinguir entre adolescentes con consumo problemático y no problemático. Estos resultados demuestran la utilidad del MMPI-A para evaluar a adolescentes chilenos con sospecha de consumo de drogas e incentivan el estudio, adaptación y utilización de este instrumento en Latinoamérica.

RESUMO

Este estudio reporta las características psicométricas de las dos escalas de Psicopatía del MACI y evalúa su utilidad para pesquisar y describir a adolescentes con alta psicopatía. Cuatro grupos representantes del continuo adaptación-desadaptación social respondieron el MACI y un autorreporte de comportamiento social adolescente. El análisis factorial de las escalas determinó estructuras de dos y tres factores, respectivamente, que son respaldadas por los modelos de psicopatía de Hare y de Cookie y Michie. Un algoritmo desarrollado con las puntuaciones de estas escalas identificó y permitió caracterizar un grupo de 49 jóvenes (11.2 % de la muestra) con alta psicopatía. Se discuten las características psicométricas y la utilidad de estas escalas para identificar a adolescentes con perfiles psicopáticos.

This study reports psychometric characteristics for two Psychopathy scales developed with the MACI and assess their utility for screening and describing high psychopathic adolescents. Four groups representing the social adjustment and maladjustment continue answered the MACI and a self report about adolescent social behaviour. A factorial analysis of the psychopathy scales determined structures formed by two and three factors which are supported by the models of psychopathy presented by Hare and by Cookie and Michie. An algorithm developed with these scales-scores identified and allowed to characterize a group of 49 adolescents (11.2 % of the sample) with high psychopathy. Psychometric characteristics and the utility of these two scales for identifying adolescents with psychopathic profiles are discussed.

RESUMO

Esta investigación determinó las características psicométricas del Psychopathy Checklist: Youth Version (PCL:YV; Forth, Kosson & Hare, 2003) en una muestra de 30 adolescentes chilenos, varones, infractores de ley. El análisis de confiabilidad arrojó un alfa = 0.41 para la escala total e indicadores más elevados para sus cuatro facetas (alfa entre 0.53 y 0.76). La validez concurrente establecida en relación a las escalas del Inventario Clínico para Adolescentes de Millon (MACI; Millon, 1993) mostró relaciones significativas moderadas entre el puntaje total del PCL:YV y las escalas del MACI relacionadas con el constructo de psicopatía. Además, se evaluó su relación con dos escalas de psicopatía desarrolladas conceptualmente con ítems del MACI. Los resultados indican que el PCL:YV presenta indicadores de confiabilidad y validez suficientemente adecuados para continuar su estudio en muestras chilenas con el fin de utilizarlo, en un futuro cercano, en la toma de decisiones profesionales relativas a jóvenes infractores de ley.

This research was aimed to determine the psychometric characteristics of the Psychopathy Checklist: Youth Version (PCL:YV; Forth, Kosson & Hare, 2003) in a sample of 30 Chilean male, juvenile offenders. Reliability analysis showed an alpha = 0.41for the total scale and higher indexes for its four facets (alpha between 0.53 and 0.73). The concurrent validity with the Millon Adolescent Clinical Inventory (MACI; Millon, 1993) showed significant associations among the total PCL:YV score and MACI scales related to the psychopathy construct. Besides, the association with two psychopathy scales that were conceptually developed by taking selected MACI items, was assessed. Results indicate that the PCL:YV presents reliability and validity indexes good enough to continue its study in Chilean samples to be use, in the near future, for taking professional decisions with relation to juvenile offenders.
