The purpose of this study was to validate the Addiction Exercise Inventory (EAI) in the Spanish context. Five hundred and eighty-four university students participated in the study, completing a questionnaire that assessed exercise addiction, exercise frequency and intensity. The results supported the factor structure of the EAI model. An alpha value of .70 and high level of temporal stability (ICC = .92) were obtained. The structure of the model was invariant across gender. A group of 87 students (14.9%) obtained a total score equal to or higher than 24 in the EAI and were classified as being at risk of exercise addiction. Students exercising more than three days per week at high intensity obtained higher scores in exercise addiction than students exercising at low-medium intensity, regardless of their frequency. The findings of this study showed the reliability and validity of the EAI in a Spanish context, providing a practical instrument that allows screening for exercise addiction.

The purpose of this study was to validate the Spanish version of Motl and Conroy’s model of the Social Physique Anxiety Scale (SPAS–7). To achieve this goal, a sample of 398 secondary school students was used, and the psychometric properties of the SPAS–7 were examined through different analyses. The results supported the seven-item model, although the item 5 did not show any significant correlation with two items from this model and had a lower factor loading than the rest of items. The structure of the model was invariant across gender and Body Mass Index (BMI). Alpha value over .70 and suitable levels of temporal stability were obtained. Girls and students classified according to the BMI as overweight and obese had higher scores in social physique anxiety than boys and the group classified as underweight and normal range. The findings of this study provided reliability and validity for the SPAS–7 in a Spanish adolescent sample.

Acquiring specific training in disability seems to be a key aspect for achieving school inclusion. Teachers who receive such prior training would be more prepared to address diversity in the classroom, which could be related to their perception of self-efficacy. The aim of this study was to validate the Spanish version of the Self-Efficacy Scale for Physical Education Teacher Education Majors toward Children with Disabilities (SE-PETE-D). Two hundred and eighteen in-service physical education teachers participated in this study, with a M_age = 38.06 years and M_{teaching  experience} = 11.72 years. To obtain the three subscales resulting from intellectual, physical, and visual disabilities, several exploratory and confirmatory factor analyses were conducted. The results supported three independent models made up of three factors (intellectual, physical, and visual disabilities). The structure of the models was invariant with respect to gender, the educational stage in which the teaching was taking place, previous teaching experience, previous training, and previous experience in adapted or inclusive physical activity and sports. The subscales presented high reliability values for Cronbach’s alpha, and Omega’s index ≥0.81. This study provides evidence of the validity and reliability of an instrument to measure the perceived self-efficacy of physical education teachers to include students with disabilities in their classes and is the first study to be applied with in-service teachers. In addition, some methodological and conceptual limitations of the original scale are identified, opening new lines of work in relation to training situations to assess the perception of self-efficacy or the type of disability.
