The purpose of this study was to determine the validity and reliability of the Power Walker® 610(PW) pedometer for step counting in children. The study sample was composed of 30 boys and 22 girls, from 8-13 years old. Participants were equipped with both a PW and a Digiwalker® SW-200(DW) pedometers and walked 400 m around an outdoor athletic track…

Early childhood educators (ECEs) play a vital role in encouraging healthy physical activity (PA) in childcare. As such, measuring ECEs' self-efficacy to facilitate such programming is important. The "ECE Confidence in Outdoor Movement, PA, and Sedentary and Screen Behaviors" (ECE-COMPASS) questionnaire (30 items) was developed via expert…

The purpose of this study was to examine the validity of a novel technique determining parent-child proximity using Bluetooth-enabled accelerometers. Nineteen parents and children (18-60 months; 38.4 ± 13.2 months) wore an ActiGraph wGT3X-BT accelerometer for 7 days. Parental accelerometers continuously emitted a Bluetooth signal, while children's…

The Neighborhood Physical Activity Questionnaire allows to assess physical activity within and outside the neighborhood. Study objectives were to examine the criterion-related validity and health/functioning associations of Neighborhood Physical Activity Questionnaire-derived physical activity in German older adults. A total of 107 adults aged…

The purpose of this study was to compare the validity and reliability of three short physical activity self-report instruments to determine their potential for use with university student populations. The participants (N = 155; 44.5% male; 22.9 ± 5.13 years) wore an accelerometer for 9 consecutive days and completed a single-item measure, the a…

Purpose: The study aimed to determine the validity of the Fitbit Charge 2 (FC2) for measuring PA steps in college physical education settings using the Yamax SW-200 (YX) as the criterion device. Methods: Undergraduate students (n = 17) worn both FC2 and YX in two conditions (i.e., controlled and college physical education settings). The absolute…

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…

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…

The accurate measurement of health-related physical activity (PA), often interpreted as either 150 min/week of at least moderate-intensity PA (U.S. Department of Health and Human Services, 2008) or at least 30 min of at least moderate-intensity PA on 5 or more days per week (Australian Government Department of Health and Ageing [AGDHA], 2005;…

Current interest in promoting physical activity in the school environment necessitates an inexpensive, accurate method of measuring physical activity in such settings. Additionally, it is recognized that physical activity must be of at least moderate intensity in order to yield substantial health benefits. The purpose of the study, therefore, was…

This project describes the development of a resource designed to facilitate the exploration of factors influencing physical activity within school settings across multiple levels. Using a socio-ecological framework, the study draws upon factors across three domains that potentially impact physical activity levels within school settings: The…

The present study explores the validity of a recent stages of change (SoC) measure and algorithm among a sample of late adolescents. MANOVA and structural equation modeling are used to assess the relationship between five SoC groups (precontemplation, contemplation, preparation, action, and maintenance) and a set of dependent measures including…

Subjective Task Value (STV) is a multidimensional construct of values predominantly used to examine western culture (Eccles et al., 1983); it is influential in motivating individuals to make choices and display long-lasting behaviours. While existing studies were conducted with western populations, the manifestation of value has yet to be…

This study examined validity evidence for the Australian version of the Neighborhood Environment Walkability Scale (NEWS-AU). A stratified two-stage cluster sampling design was used to recruit 2,650 adults from Adelaide (Australia). The sample was drawn from residential addresses within eight high-walkable and eight low-walkable suburbs matched…

Accurate measurement of physical activity is fundamentally important in epidemiological research of physical activity behavior. A widely used telephone-based physical activity questionnaire was compared with other methods of administration and objective measures (pedometers and accelerometers) among 80 adults (43 women). The telephone…
