Objetivo: O Strenght Model of Self-Control (Muraven & Baumeister, 2000; Muraven, Tice & Baumeister, 1998) engloba um conceito denominado por dificuldades autorregulatórias. Estas dificuldades são resultantes da incapacidade, de cada um, para exercer controlo sobre as suas próprias respostas. São um conceito pouco estudado nos comportamentos de saúde geral, em parte, devido à inexistência de um instrumento que permita o estudo desse conceito nesse tipo de contexto. O propósito deste estudo foi contribuir para a validação da versão portuguesa do questionário EXACTED – Conflitos, Tentações e Depleção do Ego no Exercício Físico (Chamberland, Miquelon & Dumont, 2014), através da análise das suas qualidades psicométricas. Método: Participaram neste estudo 190 sujeitos, praticantes (n=132) e não-praticantes de atividade física (n=57) de ambos os sexos (F=58,9%) com idades compreendidas entre os 18 e os 69 anos (M=28,94; DP=10,366). Resultados: Foram obtidos bons valores de consistência interna para o questionário e suas subescalas. A Análise Fatorial Confirmatória (AFC) revelou índices de qualidade de ajustamento inferiores aos obtidos no estudo original do instrumento, para o modelo de três-fatores original e ajustado, tanto para a amostra total como apenas para os praticantes de AF. E os testes t-student demonstram diferenças significativas entre praticantes e não-praticantes. As correlações de Pearson demonstram a existência de associação negativa e significativa com o questionário do Hábito. Conclusões: Estes resultados contribuem para a validação portuguesa do questionário EXACTED, sugerindo vantagens na reformulação/eliminação de alguns itens.
ABSTRACT: Aim: Strength Model of Self-Control (Muraven & Baumeister, 2000; Muraven, Tice & Baumeister, 1998) encompasses a concept referred as self-regulatory difficulties. These difficulties are due to the inability of each to exercise control over their own responses. Is a concept little studied in general health behaviors, in part because of the absence of an instrument for the study of this concept in this kind of context. The purpose of this study was to contribute to the validation of the Portuguese version EXACTED - Exercise Against Conflicts, Temptations and Ego Depletion (Chamberland, Miquelon & Dumont, 2013), through the analysis of its psychometric properties. Method: The sample consisted of 190 individuals, practitioners (n = 132) and physical activity non-practitioners (n = 57) of both genders (F = 58.9%) aged 18 to 69 years (M = 28.94, SD = 10.366). Results: The total scale and each domain presented good internal consistency. The Confirmatory Factor Analysis (CFA) confirmed the three-factor structure (Conflicts, Temptations and Ego Depletion), although with poorer adjustment quality indices than those obtained in the original study of the instrument, both for the total sample and for the sub-group of exercisers. As expected, there were significant differences between exercises and non-exercisers with regards to their regulatory difficulties. Furthermore, a higher difficulty in regulating exercise behavior was associated with lower levels of habit (automaticity). Conclusions: These results contribute to the validation of the Portuguese version of the EXACTED questionnaire, suggesting advantages in reshaping / removal of some items.
