Self-determination theory and physical activity among breast cancer survivors

The study aim was to examine constructs of autonomy support and competence as well as the motivation continuum from the self-determination theory (SDT) as a framework for understanding physical activity (PA) motivation and behavior in breast cancer survivors. Questionnaires assessing demographics, medical factors, PA, motivation continuum, perceived autonomy support, and competence were completed by 558 breast cancer survivors. Results showed that lymphedema (chi2 = 7.9, p < .01) (chi2 = 4.6, p < .05) were associated with meeting PA guidelines. Moreover, survivors meeting PA guidelines reported more identified regulations and intrinsic motivation (p < .01), autonomy support (p < .01), and competence (p < .01). Forced entry hierarchical regression analysis showed that SDT constructs explained 20.2% (p < .01) of the PA variance. Significant independent SDT predictors included identified regulation (Beta = .14, p < .05) and competence (Beta = .23, p < .01), with autonomy support approaching significance (Beta = .9, p = .057). SDT may be a useful model for understanding PA motivation and behavior in breast cancer survivors.     

The association of objectively determined physical activity behavior among adolescent female friends

The purpose of this study was to examine the extent to which physical activity among adolescent female friends is interdependent. The participants were 318 adolescent girls with a mean age of 16.0 years (range: 15-18 years). Pedometry was used to assess physical activity over 4 days. The relationship between an individual girl and her first-nominated reciprocal friend's physical activity level was moderate (r = 0.45, 90% confidence interval = 0.31, 0.56), when the friendship was nonreciprocal it was trivial (r = -.06, 90% confidence interval = -.36 .25). Friends'physical activity levels explained between 27% and 32% of an individual's pedometer-determined physical activity level. Reciprocity of friendship is an important variable to consider when understanding the relationship between adolescent female friends' physical activity. When friendships are reciprocal, there is a stronger relationship between friends' physical activity.     

Career evolution and knowledge of elite coaches of swimmers with a physical disability

In the last decade there has been an increase in empirical research on coaches of elite able-bodied athletes, while coaches of athletes with a disability have generally been overlooked. Thus, the purpose of the current study was to address this oversight by examining the career evolution and knowledge of these coaches. Six elite coaches of swimmers with a physical disability were interviewed using an unstructured, open-ended interview format. Results revealed information pertaining to the coaches' backgrounds, career evolution, and knowledge in training and competition. As well, all coaches stressed the importance of coaching their athletes as an elite swimmer as opposed to coaching a swimmer with a disability.     

Assessing preschool children's physical activity: the Observational System for Recording Physical Activity in children-preschool version

In this paper we present initial information concerning a new direct observation system-the Observational System for Recording Physical Activity in Children-Preschool Version. The system will allow researchers to record young children's physical activity levels while also coding the topography of their physical activity, as well as detailed indoor and outdoor social and nonsocial contextual information. With respect to interobserver agreement (IOA), the kappa and category-by-category agreement mean of those obtained for the three illustrative preschools were generally above .80. Hence, our IOA data indicated that trained observers in the three preschools frequently agreed on the eight observational categories and accompanying codes. The results for preschoolers' level of physical activity indicated they spent the majority of observational intervals in sedentary activity (i.e., more than 80% intervals) and were observed in moderate to vigorous physical activity much less frequently (i.e., 5% or fewer intervals). For the 15 indoor and 12 outdoor activity contexts, variability across both the activity contexts and the three preschools were evident. Nevertheless, three classroom contexts-transition, snacks, and naptime--accounted for the greatest porportion of coded activity contexts for the children. In the three preschools, 4 of 17 physical activity types--sit and squat, lie down, stand, and walk--accounted for the topography of much of children's physical activity behavior Systematic observation of more representative preschool samples might better inform our present understanding of young children's physical activity in community preschool programs.     

Children’s metabolic expenditure during object projection skill performance: New insight for activity intensity relativity

Objective: To examine children’s energy expenditure (EE) during object projection skill performance at three intensity intervals. Methods: Children’s (42, Mage = 8.1) average metabolic equivalents of task (METs) were calculated using a COSMED K4b2 while they repeatedly performed blocks of kicking, throwing (overhand), and striking (two-handed) during 6, 12, and 30-s interval conditions. A repeated-measures analysis of covariance examined differences in METs while controlling for skill level. Results: Data indicated a main effect for interval condition (df = 2, 123, F = 94.36, p <.001, η2 = .605). Post hoc t-tests demonstrated decreasing performance interval times yielded progressively higher METs (p <.001) across the three conditions (30s = 4.5±0.8 METs, 12s = 6.3±1.3, 6s = 8.3±1.6). There also was a main effect for sex (df = 1,120, F = 52.28, p <.001 η2 = .305). Boys demonstrated higher METs at each performance interval (p <.001). Conclusion: Skill practice with a maximum of one trial every 30s resulted in the equivalent of at least moderate physical activity (>4.0 METs) and intervals of 6s demonstrated vigorous physical activity (>7.0 METs). Practicing/performing object projection skills, even at intervals that allow for adequate instruction and feedback (i.e., 1 trial/30s), promotes MVPA in children.     

Macroappraisal, the Next Frontier: An Approach for Appraising Large and Complex Government Institutions

“Macroappraisal, the next frontier” describes a records disposition pilot project which was based on a refinement of the current macroappraisal methodology in use at Library and Archives Canada. Still very much a work in progress, the refined approach builds upon macroappraisal theory and methodology, and this paper presents its application to Fisheries and Oceans Canada, a major federal government department in the Government of Canada. The project focused on providing the institution with total records disposition coverage based on a single archival appraisal and two Records Disposition Authorities. This paper demonstrates the feasibility of appraising records at the mandate level instead of at the function or program level. It also outlines and points to the benefits and advantages of appraising large government institutions intheir totality rather than in smaller, discrete sectors, branches, or divisions. We wish to thank the journal’s readers for their comments on an earlier draft of this article. We also wish to thank Candace Loewen for her insights, comments, and encouragement. Thanks are also extended to our colleagues who commented on various aspects of the project during Library and Archives Canada (LAC) appraisal seminars. Kerry Badgley also wishes to thank Sarah, Paul, and Shannon Badgley for providing a daily reminder of why it is important to document the past.     

Developing rigor in qualitative research: problems and opportunities within sport and exercise psychology

Qualitative research has grown within sport and exercise psychology and is now widely conducted. The purpose of this review is to discuss three commonly used ways to demonstrate rigor when conducting or judging qualitative research in sport and exercise psychology. These are the method of member checking, the method of inter-rater reliability, and the notion of universal criteria. Problems with each method are first highlighted. Member checking and inter-rater reliability are shown to be ineffective for verification, trustworthiness, or reliability purposes. Next, universal criteria within the context of Tracy’s, heavily drawn on paper within sport and exercise psychology is problematized. Throughout the discussion of each method and universal criteria more suitable possibilities for conducting rigorous qualitative research are offered. The paper concludes that to support high-quality qualitative research, scholars – including journal editors and reviewers – need to change how rigor is developed and judged, rather than perpetuate the problems with how it has been commonly evaluated in the past. Recommendations for developing rigor when conducting and/or judging qualitative research within sport and exercise psychology are also offered.
