Self-Description Questionnaire II (versión breve): evidencia de fiabilidad y validez en una muestra de adolescentes chilenos / Self-Description Questionnaire II (short version): evidence of reliability and validity in a sample of chilean adolescents

El objetivo de este estudio fue analizar la fiabilidad y validez de las puntuaciones de la versión breve del Self-Description Questionnaire II (SDQ-II-S) en población chilena. La muestra se compuso de 1255 adolescentes chilenos, con un rango de edad de 13 a 17 años (M=15.10; DT=1.30). El análisis factorial confirmatorio corroboró la estructura original de 11 factores correlacionados del SDQ-II-S. La multidimensionalidad del cuestionario también fue avalada por la pequeña magnitud de las correlaciones entre los 11 factores (M = 0.26). Los coeficientes alfa de Cronbach variaron desde 0.70 hasta 0.84, y se destacó una adecuada fiabilidad. Para profundizar en el análisis de la validez de constructo del SDQ-II-S, se relacionaron las puntuaciones de las diferentes escalas con puntuaciones en medidas de ansiedad (Inventario de Ansiedad Estado-Rasgo) y autoeficacia (Escala de Autoeficacia Percibida Específica de Situaciones Académicas). Los resultados pusieron de manifiesto que estos cuestionarios permiten analizar constructos diferenciados aunque relacionados. Los datos de este trabajo destacan que el SDQ-II-S presenta adecuadas propiedades psicométricas en población chilena, contrarrestando las carencias existentes en lo que respecta a la evaluación del autoconcepto, y resaltan interesantes aplicaciones tanto en el ámbito aplicado como en el de la investigación.

Objective To test the reliability and validity of the short version of depression-anxiety-stress scale (DASS-21) for students in the disaster region.Methods DASS-21 and the Chinese version of UCLA PTSD Reaction Index for DSM-IV,Revision I were used to evaluate psychological health among 876 students from grades 5 to 9 after Ya' an earthquake.Results (1) Each of the items had a good distinction degree,with CR value ranging from 9.268 to 22.438 (P＜ 0.01),and the correlation coefficients ranged from 0.306 to 0.742.(2)The Cronbach' s alpha coefficients ranged from 0.781 to 0.911.(3) The correlation coefficients between total score and each dimension ranged from 0.714 to 0.914,and the correlation coefficient between PTSD and total DASS score,depression anxiety and stress score was 0.626-0.774.(4)Through the item analysis and explore factor analysis,the revised scale contained 21 items and 3 subscales which could explain 47.813％ of the total variance(KMO =0.937,x2 =3126.85,df=210,P＜0.01),and the results of confirmatory factor analysis supported the three-factor model (x2/df=4.180,P＜0.01,PCFI =0.728,CFI =0.904,IFI =0.905,TLI =0.881,and RMSEA =0.060),and the load of each item was between 0.339 to 0.715.Conclusion The short version of DASS-21 is reliable and valid,and can be used as a tool for post-disaster stress assessment on local students.

A short version of the questionnaire of metamemory in adulthood (MIA) in portuguese

The aim of this study was to develop a short version of the Metamemory in Adulthood Questionnaire (MIA) in Brazilian Portuguese. The original MIA is an instrument in english composed by 108 items, divided into seven dimensions of metamemory (Strategy, Task, Capacity, Change, Anxiety, Achievement and Locus). Despite of being widely used, the extension of the instrument makes its application impractical in many contexts, reinforcing the need for a short version. A total of 472 participants answered the original full version of the MIA. First, Item Response Theory (IRT) analyses revealed that nine items of the instrument could be excluded due to poor infit and outfit values. After exploratory factor analyses, the 99 items left were judged by five experts that chose the most appropriate items following previously established criteria (factor loading, repetitiveness, bad writing, and temporal/cultural inadequacy). A 39-items version (MIAr) was obtained, with the same factorial structure of the original MIA. The MIAr demonstrated satisfactory internal consistency indexes, as well as evidences of convergent validity and validity based on the response process. The results revealed that the MIAr achieved good psychometric properties, serving as a more parsimonious and practical option for metamemory assessment. (AU)

Validação da versão reduzida da escala de comportamento interpessoal para adolescentes Portugueses / Validation of the short version of the scale for interpersonal behavior for Portuguese adolescents

Este trabalho apresenta a adaptação linguística para português da Escala de Comportamento Interpessoal - versão reduzida, e a avaliação das suas características psicométricas, em uma amostra de adolescentes tardios (dos 16 aos 21 anos; N = 872). Foi encontrada uma organização interna em quatro dimensões e uma medida geral para os dois componentes avaliados: desconforto ao ser assertivo e frequência de prática de comportamento assertivo. Todas as medidas obtiveram valores aceitáveis de consistência interna e níveis moderados de validade por relação com outras variáveis, face à versão reduzida da Escala de Assertividade de Rathus. Algumas diferenças por sexo foram observadas. Este instrumento mostrou-se útil para ser empregado na avaliação e investigação em psicologia. (AU)

This work presents the Portuguese linguistic adaptation of the short version of the Scale for Interpersonal Behavior and the evaluation of its psychometric characteristics using a sample of late adolescents (aged 16 to 21 years; N = 872). An internal organization of four dimensions was found along with a general measure for the two components under evaluation: discomfort while being assertive and frequency of practicing assertive behavior. All measures obtained acceptable internal consistency values and moderate levels of validity based on the relation to other variables, namely the short version of Rathus Assertiveness Scale. Some sex differences were observed. The instrument showed to be useful to be employed for evaluation and research in psychology. (AU)

Versión breve del STAI en adolescentes y universitarios españoles / STAI short version in adolescents and college Spanish

El STAI es uno de los instrumentos de evaluación psicológica más empleados, generándose diversas versiones breves del mismo. No se han hallado versiones breves en las que se haya comprobado el ajuste para muestras de adolescentes ni universitarios españoles. El objetivo de este artículo es comprobar cuál de las versiones cortas propuestas en la literatura tiene un mejor ajuste en adolescentes y universitarios. Para ello, se aplicó el STAI a 482 adolescentes escolarizados y 510 estudiantes universitarios, de diversas ciudades españolas. Mediante AFC se evaluó el ajuste de cinco versiones breves del STAI. En los universitarios hay dos modelos en los que se observa un buen ajuste. En los adolescentes no ajusta ningún modelo. Puede que el proceso de diferenciación emocional con la edad explique que en los adolescentes las versiones breves halladas (siempre con adultos) no serían válidas, sí pudiendo emplearse con universitarios.

The STAI is an instrument very used, generating different short versions. We found no short versions in which it is tests the fit for teenagers and college samples Spanish. The aim of this paper is to test which of the short versions proposed in the literature have a better fit in adolescents and college students. To do this, we applied the STAI to 482 adolescent students and 510 university students from different Spanish cities. Through AFC we evaluated five short versions of the STAI. At the university there are two models in which there is a good fit. In adolescents not fit any model. Maybe the emotional differentiation process explains that the found short versions (always with adults) are not valid in teenagers, and can be used with university students.
