Análisis Psicométrico de la Escala Autoeficacia en Conductas de Cuidado de la Salud Física en Universitarios de Primer Ingreso

Psychometric properties in the self-efficacy scale on behavior of physical health care were studied. The sample was of 2089 individuals: 902 women and 1187 men, incoming students to the majors offered at the Autonomous University of Chihuahua in Mexico, with an average age of 18.23 years. The analysis of psychometric properties has shown that a trifactorial structure is feasible and adequate according to the psychometric requirements established when the informants are the students. The three factors structure, attending statistic and substantial criteria has shown adequate adjustment factors, reliability (except on physical health and hydration factors) and validity indicators. Besides, factorial analyses taken with sub-samples 1 and 2 fully demonstrate these results.

Autoeficacia Percibida en la conducta Académica de Estudiantes Universitarias

A study has been done to characterize female students who choose one of the degrees offered by the Universidad Autonoma de Chihuahua in Mexico, in terms of the perceived self-efficacy in their academic performance. The sample consisted of 902 female freshmen college students from seven disciplines with a mean age of 18.1 years. The research method adopted has a quantitative focus with a descriptive design employing a survey. The results show that the profiles of selfefficacy in academic behavior is very similar between students of different disciplines, and that the behavior related to communication skills represents an area of opportunity for improvement in incoming college students. Also, it was observed that the profiles of current, desired and achievable efficacy are related: the higher the perceived self-efficacy, greater desire and more chances of being effective. This allows concluding that if any of them can be improved, the other two will also do it.

Psychometric Properties of the Spanish Adaptation of the Tactical Skills Inventory for Sports in the School Context.

Tactical skills in sport are the basis for current models of invasion team sports instruction, and relate to other psychological variables that exert a mediating influence on peoples normal physical activity. This study aimed to validate the Spanish adaptation of the Tactical Skills Inventory for Sports by Elferink-Gemser, Visscher, Richart, and Lemmink (2004) and verify its factorial invariance. The sample included 540 participants 12.89 ± 1.73 years of age (10 to 17 years old; 333 males and 207 females). The adaptation and translation of the original questionnaire followed the methodological steps established by the International Test Commission. Then two measurement models with the original questionnaires four-factor structure were compared. Confirmatory analyses were conducted using the software AMOS 21 and maximum likelihood estimation. Results indicated a four-factor structure (positioning and deciding, knowing about ball actions, knowing about others, acting in changing situations) was viable and showed goodness of fit to the data, with adequate indices of reliability (α between .72 and .86) and validity (GFI = .955; RMSEA = .044; CFI = .974), and strong evidence of stability in the factor structure. Moreover, factorial invariance was observed between participants who do and do not practice team sports, with practitioners scoring higher than non-practitioners on all factors (p < .001; effect sizes between .97 and 1.08).

Psychometric properties of the physical self-concept questionnaire with Mexican university students

This study analyzes, in a sample of Mexican students, the factor structure of the Physical Self-Concept Questionnaire of Goñi, Ruiz de Azúa, and Rodríguez (2006), which assesses physical ability, physical fitness, attractiveness, strength, general physical self-concept, and global self-concept. A representative sample of 1,466 Mexican university physical education students was selected (754 men, 712 women; M age = 20.6 yr., SD = 2.0). Confirmatory factor analysis showed a two-factor structure (motor competency and physical attractiveness). The two-factor structure, regarding statistical and substantive criteria, had good fit indices. Results of the factor analyses carried out with the sub-samples indicated a strong stability and evidence for the factor structure obtained. The findings support the use of this questionnaire to measure physical self-concept in Mexican university students. Future studies should replicate these findings in other populations.

The Spanish Adaptation of the Sport Motivation Scale-II in Adolescent Athletes

The aim of this study was to adapt and validate the Spanish version of the Sport Motivation Scale-II (S-SMS-II) in adolescent athletes. The sample included 766 Spanish adolescents (263 females and 503 males; average age = 13.71 ± 1.30 years old). The methodological steps established by the International Test Commission were followed. Four measurement models were compared employing the maximum likelihood estimation (with six, five, three, and two factors). Then, factorial invariance analyses were conducted and the effect sizes were calculated. Finally, the reliability was calculated using Cronbach’s alpha, omega, and average variance extracted coefficients. The five-factor S-SMS-II showed the best indices of fit (Cronbach’s alpha .64 to .74; goodness of fit index .971, root mean square error of approximation .044, comparative fit index .966). Factorial invariance was also verified across gender and between sport-federated athletes and non-federated athletes. The proposed S-SMS-II is discussed according to previous validated versions (English, Portuguese, and Chinese).

Invarianza Factorial de una Escala de Autoeficacia sobre Conductas Académicas en Universitarios Hombres y Mujeres

The present study analyses the psychometric properties of the a self-efficacy scale on academic behavior in university students, men and women. The overall sample consisted of 1545 subjects: 616 women and 929 men, with a mean age of 18.11 years and 18.27 years, respectively. Psychometric analysis showed that a three-factorial structure (attention, communication and excellence) was viable and adequate for both populations, men and woman, according to the established psychometric requirements when the informers are the students themselves. The results showed that factor structure, factor loadings and intercepts of the instrument could be considered invariant across groups. However, there are differences between groups for the means of the factors attention and excellence.
