This study aimed to assess the agreement in physical activity (PA) estimates from Garmin Vivofit Jr. 3 (VFJ 3) and Fitbit Ace 3 (Ace 3) with a research-grade accelerometer (wGT3X-BT) in children under free-living conditions. Twenty-five children (Girls: 56%, Age: 10.1 ± 2.5 years, BMI: 17.1 ± 2.4 kg/m2) performed daily activities for 7 consecutive…

The purpose of this study was to explore the validity of evidence for self-efficacy to regulate physical activity scale (SERPA) measurement using an exploratory latent variable approach. The objectives were to explore the dimensionality, temporal invariance, and external validity of scores produced by the SERPA, a modified version of the barriers…

This study aimed to determine the validity of the ActiGraph wGT3X-BT for step counts (SC) at five different body locations in laboratory settings. A total of 29 male adults participated in this study. The participants walked or ran for different speeds on the treadmill while wearing ActiGraph wGT3X-BT on their right wrist (RW), left wrist (LW),…

This study aimed to develop and test MyPL, a questionnaire that measures self-reported physical literacy (PL) among children and adolescents. First, the item pool was developed and adapted, and face validity was tested with cognitive interviewing. Then, factor structures were identified through multidimensional scaling and exploratory factor…

This study aimed to review the validity and/or reliability of light-intensity physical activity (LPA) questionnaires and identify the most suitable questionnaires for measurement of LPA in adults. Following the PRISMA-P 2020 guidelines, we searched MEDLINE, PsycINFO, CINAHL, Scopus, Embase, and MedNar. Only studies that targeted adults [greater…

The present study aimed to validate the Chinese version of the Tendency to Avoid Physical Activity and Sport Scale (TAPAS) among university students living in Hong Kong to assess weight and body image concerns. A convenience sample of 787 students (63.5% females; 24.5% overweight) were recruited online. The factor structure of the scale was…

This study examines the convergent validity of the Physical Activity Questionnaire for Children (PAQ-C) for assessing moderate-to-vigorous and total physical activity (PA) in school children. 430 participants (51.6% girls) aged 9-12 years provided valid accelerometer data (wGT3X-BT) and completed the PAQ-C. Convergent validity was assessed using…

This study evaluated the reliability and construct validity of the 51-item Effective Early Childhood Physical Literacy Pedagogue self-report instrument (ECE-PLP) measuring Early Childhood Educators' (ECEs) perceived physical literacy (PPL) capabilities, knowledge, and practices for effectively promoting PL in young children. 494 ECEs completed the…

Mindfulness is growing in popularity with the potential to improve many favorable health outcomes. Physical activity (PA) is crucial for improving health, however, there is no Turkish scale to measure mindfulness during PA. The purpose of this study was to translate, culturally adapt, and validate the Turkish version of The State Mindfulness Scale…

No Spanish-language tool exists to assess physical activity in people with spinal cord injuries. This work aimed to provide a valid Spanish version of the Physical Activity Recall Assessment for People with Spinal Cord Injury (PARA-SCI). It was conducted in three phases. First, translation and cross-cultural adaptation. Second, a reliability…

The International Physical Activity Questionnaire-Short Form (IPAQ-SF) is a globally-used self-report measure of physical activity (PA). Validity evidence exists; none has evaluated the IPAQ-SF with reduced recall time. This study evaluates absolute and relative agreement for PA at all intensities, and relative to recommended guideline…

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…

The objective of this study was to provide initial validity evidence for responses to the newly developed Well-Being Actions Self-Efficacy (WBASE) scale from adults with obesity under an exploratory latent variable approach. Longitudinal data (N[subscript baseline] = 667 and N[subscript 30 days post-baseline] = 550) from the Well-Being and…

To evaluate the validity of the Pregnancy Physical Activity (PA) Questionnaire (PPAQ) for long-term PA recall. Forty-eight women completed the PPAQ at 21, 32 weeks gestation, and 12 weeks postpartum. These women were emailed three separate PPAQs between two months and eight years after originally completing the questionnaires to recall their PA…

The objective of this study was to provide initial validity evidence for responses to the newly expanded version of the I COPPE Actions scale from adults with obesity under an exploratory latent variable approach. Longitudinal data from the 2018 Fun For Wellness Effectiveness Trial (ClinicalTrials.gov, identifier: NCT03194854) were reanalyzed in…
