ABSTRACT
El concepto de vitalidad subjetiva se refiere a la sensación de estar "vivo" y "alerta"; es decir, de tener energía disponible para sí mismo, reflejando una experiencia psicológica de entusiasmo e inspiración. El propósito de esta investigación fue traducir y analizar las propiedades psicométricas de la versión Portuguesa de la Subjective Vitality Scale, en una muestra de 935 practicantes de ejercicio, ambos hombres (344) y mujeres (591). Los resultados del análisis factorial confirmatorio confirmaron la estructura unifactorial de la escala (S-B χ² = 34.93; p = .000; χ²/gl = 3.88; NNFI = .961; CFI = .970; RMSEA = .074 con 90% CI = .049 - .101). Asimismo, se obtuvieron resultados que evidenciaron validez concurrente con las versiones portuguesas de la Rosenberg Self-Esteem Scale y de la Satisfaction with Life Scale. Del mismo modo, se documentan evidencias de fiabilidad, analizada como consistencia interna y estabilidad temporal. Los resultados apoyan preliminarmente el uso de la versión portuguesa de la Subjective Vitality Scale en el contexto del ejercicio.
The concept of subjective vitality refers to the state of feeling alive and alert; to have energy available to oneself. The aim of the present study was to translate and analyze the psychometric properties of the Portuguese version of the Subjective Vitality Scale in a sample of 935 exercisers, both men (344) and women (591). The results of the confirmatory factor analysis confirmed the good adjustment of the original factorial model (S-B χ² = 34.93; p = .000; χ²/gl = 3.88; NNFI = .961; CFI = .970; RMSEA = .074 con 90% CI =.049-.101). Also, concurrent validity was obtained through the application of the Portuguese versions of the Rosenberg Self-Esteem Scale and Satisfaction with Life Scale. In the same way, reliability of the scale throughout the analysis of internal and temporary consistency was also demonstrated. The present findings support the use of the Portuguese version of the Subjective Vitality Scale to assess vitality among Portuguese exercisers.
ABSTRACT
O objetivo do presente estudo foi o de traduzir e avaliar as propriedades psicométricas do Perceived Autonomy Support Exercise Climate Questionnaire, para avaliar a perceção do suporte de autonomia dado pelo professor de fitness, em linha com a teoria da autodeterminação. Para este propósito, recorreu-se a uma amostra de 935 praticantes de exercício, masculinos (N = 344) e femininos (N = 591), pertencentes a 16 academias da zona de Lisboa e litoral oeste de Portugal. As análises efetuadas revelaram que a versão traduzida possuía uma adequada validade interna, validade temporal, validade de construto e validade preditiva, dando sustentação à sua utilização em praticantes de exercício Portugueses...
