          Abstract

          RESUMEN El presente trabajo evalúa las propiedades psicométricas de un cuestionario de Teoría de la Conducta Planeada en la actividad física en una muestra de alumnado universitario con discapacidad. El cuestionario fue administrado a 772 universitarios españoles con discapacidad. La estructura factorial se validó mediante análisis factorial confirmatorio, y para valorar la validez de criterio se llevaron a cabo correlaciones de Spearman entre los constructos de la Teoría de la Conducta Planeada y el tiempo dedicado a la actividad física. La fiabilidad se evaluó mediante el coeficiente alfa de Cronbach. Se evaluaron dos modelos, uno de cuatro factores y uno de cinco factores. El modelo de cinco factores fue el que mejores resultados presentó (CFI=,97; RMSEA=,057; IC 90%=,049-,066) (α=0,870). También se encontraron relaciones positivas entre todos los constructos de la Teoría de la Conducta Planeada y el tiempo dedicado a la actividad física. Los resultados muestran que el instrumento desarrollado resulta válido y fiable y sugieren que “Autoeficacia” y “Controlabilidad” deben considerarse dos factores independientes dentro del modelo. En conclusión, el cuestionario que se ofrece puede ser una herramienta útil para avanzar en el estudio de los factores psicosociales que afectan a la práctica de actividad física de las personas con discapacidad.

          RESUMO O presente trabalho avalia as propriedades psicométricas de um questionário de Teoria do Comportamento Planejado na atividade física em uma amostra de estudantes universitários com deficiência. O questionário foi administrado a 772 estudantes universitários espanhóis com deficiência. A estrutura fatorial foi validada pela análise fatorial de confirmação e para avaliar a validade do critério, as correlações de Spearman foram realizadas entre as construções da Teoria do Comportamento Planejado e o tempo dedicado à atividade física. A confiabilidade foi avaliada usando o coeficiente alfa de Cronbach. Foram avaliados dois modelos, um dos quatro fatores e um dos cinco fatores. O modelo de cinco fatores mostrou os melhores resultados (CFI = 97, RMSEA = 057, IC 90% = 049-, 066) (α = 0,870). Relações positivas também foram encontradas entre todas as construções da Teoria do Comportamento Planejado e o tempo dedicado à atividade física. Os resultados mostram que o instrumento desenvolvido é válido e confiável e sugere que "Auto-eficácia" e "Controlabilidade" sejam considerados dois fatores independentes dentro do modelo. Em conclusão, o questionário oferecido pode ser uma ferramenta útil para avançar no estudo de fatores psicossociais que afetam a atividade física de pessoas com deficiência.

          ABSTRACT The aim of this study was to assess the psychometric properties of a Theory of Planned Behaviour questionnaire in physical activity in university students with disabilities. The questionnaire was administered to 772 Spanish university students with disabilities. The factorial structure was validated by confirmatory factor analysis and Spearman correlations between the Theory of Planned Behaviour constructs and time devoted to physical activity were calculated to assess criterion validity. Reliability was assessed using Cronbach's alpha coefficient. Two models were assessed, one with four factors and other one with five factors. The model with five factors obtained better results (CFI=,97; RMSEA=,057; IC 90%:,049-,066) (α=0,870). Positive relations between all the constructs of Theory of Planned Behaviour and the time devoted to physical activity were also found. The results show that the instrument developed is valid and reliable and they suggest that “Self-efficacy” and “Controllability” should be considered as two independent factors of the model. In conclusion, the questionnaire could be a useful tool in order to gain knowledge about the psychosocial factors that affect physical activity participation of people with disabilities.

            Efficacy of the Theory of Planned Behaviour: A meta-analytic review

            The Theory of Planned Behaviour (TPB) has received considerable attention in the literature. The present study is a quantitative integration and review of that research. From a database of 185 independent studies published up to the end of 1997, the TPB accounted for 27% and 39% of the variance in behaviour and intention, respectively. The perceived behavioural control (PBC) construct accounted for significant amounts of variance in intention and behaviour, independent of theory of reasoned action variables. When behaviour measures were self-reports, the TPB accounted for 11% more of the variance in behaviour than when behaviour measures were objective or observed (R2s = .31 and .21, respectively). Attitude, subjective norm and PBC account for significantly more of the variance in individuals' desires than intentions or self-predictions, but intentions and self-predictions were better predictors of behaviour. The subjective norm construct is generally found to be a weak predictor of intentions. This is partly attributable to a combination of poor measurement and the need for expansion of the normative component. The discussion focuses on ways in which current TPB research can be taken forward in the light of the present review.
