Construcción y validación de una escala de autoeficacia para la actividad física

BACKGROUND The estimation by standardized tests on belief in personal capacity to practice regular physical activity (self-efficacy for physical activity) allows us to make predictions about the actual practice of this behavior. We do not have measuring instruments suitable for this purpose, therefore, we propose to construct and validate a scale to determine levels of self-efficacy of adult users of the Primary Health Care Services for regular physical activity. METHODS Phases: 1) Develop and review the scale by expert judges. 2) A pilot study. 3) Determination of reliability and validity of the test. The sample was 388 adult users (18-65 years) of health centres from the province of Seville selected by cluster sampling (health centres) and quotas (town size, age and sex). Concurrent validity was found by the International Physical Activity Questionnaire (IPAQ) and discriminant validity by Beck Depression Inventory (BDI). RESULTS The results reported adequate content validity and high reliability (Cronbach Alpha > 0,9 in all factors and β = 0,96). Exploratory factor analysis showed three factors explaining 52,569% of the variance. The scale was sensitive to activity levels assessed by the IPAQ (F (1)= 4.131; p <0.05) and negatively correlated with BDI (r = -0,127; p <0,05). CONCLUSIONS The psychometric properties of the scale are appropriate for measuring the efficacy of adult users of Health Services to practice regular physical activity.BACKGROUND The estimation by standardized tests on belief in personal capacity to practice regular physical activity (self-efficacy for physical activity) allows us to make predictions about the actual practice of this behavior.

Validating a theory of planned behavior questionnaire to measure entrepreneurial intentions

The Theory of Planned Behavior (TPB, Ajzen, 1991) has been widely employed to predict entrepreneurial intentions. The TPB offers a coherent and generally applicable theoretical framework, which enables us to understand and predict entrepreneurial intentions by taking into account not only personal but also social factors (Krueger et al., 2000). This study presents the validation of an Entrepreneurial Intention Questionnaire (EIQ) in a sample of more than three thousand Spanish university graduates. The EIQ comprises four subscales: attitudes towards entrepreneurship, subjective norms, self-efficacy, and entrepreneurial intention. Unlike other questionnaires used in the field (Autio, Keeley, Klofsten, Parker & Hay, 2001; Krueger, Reilly & Carsrud, 2000; Liñán & Chen, 2009), EIQ follows Ajzen’s (Ajzen, 2002) methodological recommendations on how to construct a TPB questionnaire using composite measures of attitudes and subjective norms. Structural equation modeling (SEM) confirmed that the EIQ has a high reliability and predictive validity for Spanish university graduates’ entrepreneurial intentions.
