Valid measurement of youth physical activity is important and self-report methods provide convenient assessments at the population level. There is evidence that the validity of physical activity self-report varies by weight category. The aim of this study was to assess the validity of the 3-Day Physical Activity Recall (3DPAR), separately between normal weight and overweight/obese Australian youth. Accelerometer-derived physical activity variables were compared with 3DPAR variables in 155 (77 females) 11- to 14-year-olds from Adelaide, South Australia. In the whole sample, validity coefficients for self-reported moderate and moderate to vigorous physical activity were modest (rs = 0.12-0.31) and similar across gender and weight status categories. Validity coefficients for self-reported vigorous physical activity were much stronger (rs = 0.59-0.73) among overweight/obese than among normal weight participants. The validity of the 3DPAR in this study was low in the whole sample but varied according to physical activity intensity and the weight status of the child. Specifically, the 3DPAR may be appropriate for describing vigorous intensity physical activity among overweight and obese youth.

The after-school period is potentially a “critical window” for promoting physical activity in children. The purpose of this study was to qualitatively explore children’s perceptions of the factors influencing their engagement in physical activity during the after-school period as the first phase in the development of a questionnaire.
Fifty-four South Australian children age 10−13 years participated in same gender focus groups. Transcripts, field notes, and activity documents were analyzed using content analysis. Through an inductive thematic approach, data were coded and categorized into perceived barriers and facilitators according to a social ecological model.
Children identified a number of factors, including safety in the neighborhood and home settings, distance to and from places, weather, availability of time, perceived competence, enjoyment of physical activity, peer influence, and parent influence. New insights into bullying and teasing by peers and fear of dangerous animals and objects were revealed by the children.
In this study, hearing children’s voices allowed the emergence of factors which may not be exposed using existing surveys. These findings are grounded in children’s perceptions and therefore serve as a valuable contribution to the existing literature, potentially leading to improved intervention and questionnaire design.

Background: Australian 24-Hour Movement Guidelines for the Early Years were recently developed. To maximize the uptake of the guidelines, perceptions of key stakeholders were sought. Methods: Thirty-five stakeholders (11% Aboriginal or Torres Strait Islander descent) participated in focus groups or key informant interviews. Stakeholders included parents of children aged 0–5 years, early childhood educators, and health and policy professionals, recruited using convenience and snowballing techniques. Focus groups and interviews were audio-recorded and transcribed verbatim. Data were analyzed inductively using thematic analysis. Results: There was general acceptance of the Movement Guidelines. The stakeholders suggested that the Guidelines were highly aspirational and needed to be carefully messaged, so parents did not feel guilty if their child was not meeting them. Stakeholders identified that the messaging needed to be culturally appropriate and visually appealing. Dissemination strategies differed depending on the stakeholder. Conclusion: Seeking stakeholder perceptions is an important process in the development of national Movement Guidelines. This study successfully examined stakeholders’ perceptions regarding the acceptability, usability, and dissemination of the Australian 24-Hour Movement Guidelines. Effective and innovative strategies for maximizing compliance and uptake of the Guidelines should be prioritized.
