Prefrontal symptoms inventory in chile: preliminary
Abstract
ABSTRACT
Introduction. Executive functions (EF) are important variables in interrelationships of cognitive processes. Therefore, it is relevant to understand the way in which these are articulated in the execution of certain behaviors and in the appearance of certain deficits. Their adequate detection requires valid and reliable instruments that are also useful for prevention and treatment. Objective. To evaluate the psychometric properties of the Prefrontal Symptoms Inventory. Method. It was studied the factorial structure and internal consistency in a sample of Chilean university students from the Metropolitan Region (n = 211) with ages between 18 and 30 years (M = 23; SD = 2.81). Results. The factorial solution of three factors was consistent with the original questionnaire regarding the main alterations that interrogate the questionnaire (cognitive, emotional and behavioral). Discussion. The internal consistency indexes were good for the general scale, being a reliable and valid scale for the detection of cognitive, emotional and behavioral deficits, associated with the executive functions (EF).
Keywords:Â Prefrontal Symptoms Inventory, cognitive and emotional deficits, executive functions.

RESUMO
Introdução: As funções executivas (FE) são variáveis importantes nas inter-relações dos processos cognitivos. Portanto, é relevante compreender a forma em que se articulam na execução de certos comportamentos e na aparição de certos déficits. Sua detecção adequada requer instrumentos válidos e confiáveis que também sejam úteis para a prevenção e o tratamento. Objetivo: Avaliar as propriedades psicométricas do Inventário de Sintomas Pré-frontais (ISP-20). Método: Analisou-se a estrutura fatorial e a consistência interna em uma mostra de estudantes chilenos da Região Metropolitana (n = 211) com idades entre 18 e 30 anos (M = 23; DE = 281). Resultados: A solução fatorial de três fatores se mostrou coerente com o questionário original a respeito das principais alterações que perguntava o questionário (cognitivas, emocionais e comportamentais). Discussão: Os Ãndices de consistência interna foram bons para a escala geral, resultando ser uma escala fiável e válida para a detecção de déficits dos processos cognitivos, emocionais e comportamentais associados com as funções executivas (FE).
