This cross-sectional study of 504 community-dwelling Australian adults (328 females, 176 males, mean age 50.8 ± 13.0 years) sought to examine the reliability and validity of measurement scales for physical activity (PA) self-efficacy and outcome expectations. Participants completed demographic and anthropometric measurements, and a 23-item…

Experiencing mindfulness during movement-based interventions (e.g., yoga) may help support adaptive physical activity motivation processes in youth. However, there is currently no measure for assessing state mindfulness with youth within the context of physical activity. The purpose of this study was to qualitatively and quantitatively evaluate a…

We examined psychometric properties of a Modified Physical Activity Questionnaire for Children (MPAQ-C). Thirty-two parents (Study 1), 40 students (6-9 years) and one of each student's parents (Study 2), and 625 parents (Study 3) completed the MPAQ-C. The MPAQ-C (six items) measured children's physical activity (PA) after school, and during…

Based on the job demands-resources model, the study developed and validated an instrument that measures physical education teachers' job demands-resources perception. Expert review established content validity with the average item rating of 3.6/5.0. Construct validity and reliability were determined with a teacher sample (n = 397). Exploratory…

This study examined the psychometric properties of the Self-Presentational Efficacy Scale (SPES) developed by Gammage, Hall, and Martin Ginis (2004). University students (196 men and 269 women) completed the SPES and measures of social physique anxiety, fear of negative evaluation, and physical activity. Participants also completed the SPES a…

The present study was designed to examine the psychometric properties of the Chinese-translated Behavioral Regulation in Exercise Questionnaire-2 (Markland & Tobin, 2004). A sample of Chinese university students (N =555) was invited to take part in this study. Confirmatory factor analysis was employed to examine the factorial validity, and the…

The aim of the present study was to examine the validity and reliability of a multi-dimensional measure of trait anxiety specifically designed for the physical education lesson. The Physical Education Trait Anxiety Scale was initially completed by 774 high school students during regular school classes. A confirmatory factor analysis supported the…

This study assessed the performance of the original version of the Physical Self-Perception Profile (PSPP; Fox & Corbin, 1989) as compared to a revised version. University students (N = 259) participated in the study, each answering and comparing the clarity of the original and a revised PSPP. While participants found the revised version to be…

The aim of this investigation was to develop an instrument assessing the functions of self-talk (ST) in sports. Two studies were conducted for the development of the Functions of Self-Talk Questionnaire (FSTQ). In the first study, a prospective instrument was developed based on empirical evidence and a series of preliminary exploratory factor…

The research purposes were to examine the factorial and convergent validity, internal consistency, and test-retest reliability of the Exercise Dependence Scale (EDS). Two separate studies, containing a total of 1,263 college students, were undertaken to accomplish these purposes. Participants completed the EDS and measures of exercise behavior and…
