Purpose:This systematic review and meta-analysis aimed to evaluate the effect of wearable devices for improving physical activity and healthrelated outcomes in cancer survivors.Methods:CINAHL,Cochrane,Ebscohost,MEDLINE,Pubmed,ProQuest Health and Medical Complete,ProQuest Nursing and Allied Health Source,ScienceDirect,and SPORTDiscus databases were searched for randomized controlled trials published before September 1,2020,that evaluated interventions involving wearable devices in cancer survivors.Standardized mean differences(SMDs)were calculated to assess effects on physical activity and health-related outcomes.Subgroup analyses were conducted to assess whether the effects differed by interventions and cancer characteristics.Risk of bias was assessed using the Cochrane risk of bias tool.Results:Thirty-five trials were included(breast cancer,n=15,43%).Intervention durations ranged between 4 weeks and 1 year.Most trials(n=25,71%)involved pedometer-based physical activity interventions.Seven(20%)involved Fitbit-based interventions,and 3(9%)involved other wearable physical activity trackers(e.g.,Polar,Garmin).Compared to usual care,wearable devices had moderate-to-large effects(SMD range 0.54-0.87,p<0.001)on moderate-intensity physical activity,moderate-to-vigorous-intensity physical activity,total physical activity,and daily steps.Compared to usual care,those in the intervention had higher quality of life,aerobic fitness,physical function,and reduced fatigue(SMD range=0.18-0.66,all p<0.05).Conclusion:Wearable physical activity trackers and pedometers are effective tools that increase physical activity and improve health-related outcomes in individuals with cancer.Identifying how these devices can be implemented for longer-term use with other intervention components remains an area for future research. 相似文献

The authors critique the mechanistic notion of aspirations running through much research and policy‐making on educational and vocational outcomes. They present a performative model, with individuals drawing on limited social resources to express aspirations within constrained contexts. This argument is illustrated by discussion of the findings of large‐scale empirical investigation of the aspirations of 490 young people in three UK schools. Five themes from this analysis are presented and it is argued that these need to be explored in order to enrich and expand our understanding of young people's expression of aspirations. 相似文献

Adolescents struggle with setting and striving for goals that require sustained self‐discipline. Research on adults indicates that goal commitment is enhanced by mental contrasting (MC), a strategy involving the cognitive elaboration of a desired future with relevant obstacles of present reality. Implementation intentions (II), which identify the action one will take when a goal‐relevant opportunity arises, represent a strategy shown to increase goal attainment when commitment is high. This study tests the effect of mental contrasting combined with implementation intentions (MCII) on successful goal implementation in adolescents. Sixty‐six 2nd‐year high school students preparing to take a high‐stakes exam in the fall of their third year were randomly assigned to complete either a 30‐minute written mental contrasting with implementation intentions intervention or a placebo control writing exercise. Students in the intervention condition completed more than 60% more practice questions than did students in the control condition. These findings point to the utility of directly teaching to adolescents mental contrasting with implementation intentions as a self‐regulatory strategy of successful goal pursuit. 相似文献

The history of education is a worthwhile pursuit within the study of history writ-large, for education is a powerful cultural device that has been manipulated for a variety of social, political, and economic purposes. So, why is it the case that little work has been done to date on the history of American Jewish schooling? This article assesses the state of Jewish educational historiography and suggests that research has been constrained by two major factors: (1) Jewish historians have been reluctant to address educational matters, and (2) Jewish educators have been concerned foremost with the present and future, and not the past. 相似文献
