Effect of recreational sport and physical activity participation on well-being during early parenthood
BACKGROUND: Parents with children in the home may benefit considerably from sport participation, given the high levels of physical inactivity and psychosocial distress among this group. The purpose of this study was to evaluate the effectiveness of team sport participation on mental health (primary outcome) as well as other secondary psychosocial outcomes compared to an individual physical activity condition and a "date night" control condition a…
Association of 24-hour movement guideline adherence, mental health and quality of life in young adults
Background: The spread of Covid-19 and resultant infection prevention strategies have disturbed the life routine of Chinese young adults, led to reduced physical activity (PA), prolonged screen time (ST) and inadequate sleep duration (SP), and made immense influence on their mental health (MH) and quality of life (QoL). E-Health literacy (EHL) can enable citizens to use available online information to respond to the highly complex information env…
Psychological needs and exercise behaviour
OBJECTIVE: Psychological need satisfaction, from a self-determination theory (SDT) perspective, has been applied extensively to understand predictors of exercise behaviour. Dweck proposed a psychological needs framework that includes basic needs (optimal predictability, competence, acceptance), compound needs derived from combinations of basic needs (self-esteem/status, trust, control), and a superordinate compound need for self-coherence that in…
Family‐based physical activity interventions and family functioning
Family physical activity (PA) can confer multiple health benefits, yet whether PA interventions affect general family functioning has not been appraised. The purpose of this review was to evaluate studies that have examined the effect of family PA interventions, where child PA was the focus of the intervention, on constructs of family functioning. Literature searches were concluded on January 11, 2022 using seven common databases. Eligible studie…
National trends and ecological factors of physical activity engagement among U.S youth before and during the Covid-19 pandemic
These findings highlight the differing impacts of the pandemic on physical activity between children and adolescents, emphasizing the need for targeted public health interventions, particularly for adolescents whose activity levels have not recovered from the pandemic period. Age-specific physical activity interventions should consider sleep duration and neighborhood environmental factors when targeting children and mental health factors when foc…

Re-assessing the social climate of physical (in)activity in Canada
Social-ecological models suggest that a strategy for increasing population physical activity participation is to reconstruct the "social climate" through changing social norms and beliefs about physical activity (PA). In this study, we assessed whether the PA social climate in Canada has changed over a five-year period after controlling for sociodemographic factors and PA levels. Replicating a survey administered in 2018, a sample of adults in Ca…
Child and youth physical activity throughout the Covid-19 pandemic
Changes in virus-transmission habits during the Covid-19 pandemic
OBJECTIVE: The COVID-19 pandemic saw promotion of novel virus transmission-reduction behaviours, and discouragement of familiar transmission-conducive behaviours. Understanding changes in the automatic nature of such behaviours is important, because habitual behaviours may be more easily reactivated in future outbreaks and disrupting old habits may discontinue unwanted behaviours. DESIGN: = 42 ± 16y, 79% female). MAIN OUTCOME MEASURES: Within-par…
Three years on, Covid-19 is still relevant
The COVID-19 pandemic, and the related public health restrictions imposed to curb the transmission of the virus, have had an unprecedented impact on people across the globe (e.g., Krishnamoorthy et
Relationship of 24-Hour Movement Behaviors with Weight Status and Body Composition in Chinese Primary School Children

Examining whether affectively-charged motivations predict subsequent affective response during physical activity
Background Evidence suggests positive affective response during physical activity increases the likelihood of engaging in and maintaining regular activity exercise in the future. Elucidating antecedents for a positive affective response may help identify intervention strategies to increase activity. Affectively-charged motivations (e.g., desires, urges, dreading) have been posited as proximal antecedents to physical activity but have yet to be ex…

Imperialism and the Contradiction of Development
As a reflection of the direction of some socialist scholarship away from stagnationist theories of underdevelopment, Bill Warren’s article, Imperialism and Capitalist Industrialization addresses an important issue. The ambiguities and lack of theoretical sophistication of such concepts as ‘underdevelopment’ and ‘dependency’ indeed beset current Marxist analyses of the
The Reconsolidation of American Hegemony
During the early part of this decade, a number of writers asserted that we were entering a new historical period marking the end of us world supremacy. Mustering an impressive set of dramatic events, the argument against the American century was quite convincing. In the so-called third
Reply to Critics
Albert Szymanski’s attempted refutation of our thesis on the reconsolidation of us imperialism presents a ‘summary’ which does not in fact correspond to what we actually argued; offers statistical data that is largely irrelevant to the issues at stake; ignores important aspects of our position; and is
Nuclear Renewal
Investigating multiple components of attitude, subjective norm, and perceived control
The presence of two subcomponents within each theory of planned behaviour (TPB) concept of attitude (affective and instrumental), subjective norm (injunctive and descriptive), and PBC (self‐efficacy and controllability) has been widely supported. However, research has not examined whether the commonality of variance between these components (i.e. a general factor) or the specificity of variance within the subcomponents influences intention and be…

Conceptual Categories or Operational Constructs? Evaluating Higher Order Theory of Planned Behavior Structures in the Exercise Domain
The theory of planned behavior (TPB) is a popular framework for understanding the informational and motivational influences of exercise behavior. One tenet of this model that has not been examined is the belief that direct measures of TPB component constructs are organized through higher order constructs. The authors' purpose of this article was to test this higher order conceptualization in comparison with a multidimensional TPB model using stru…

Evaluating Timeframe Expectancies in Physical Activity Social Cognition
Promoting maintenance of regular physical activity (PA) is a public health priority; however, to the authors' knowledge, no researchers to date have examined whether the expectancies of proximal PA enactment are similar to the expectancies of longer maintenance. Thus, the authors' purpose in this study was to evaluate whether PA expectancies, measured with constructs of the theory of planned behavior (TPB), varied as a function of time frame (no …
Gender Differences in Belief-Based Targets for Physical Activity Intervention Among Adolescents
This Study elicited salient Theory of Planned Behavior (Ajzen, 1991) beliefs about physical activity among adolescents (Study 1) and then used these beliefs to evaluate gender differences in intention and behavior (Study 2). Study 1 was conducted with a sample ( N = 25) of Canadian adolescents, followed by Study 2 ( N = 157) where participants completed measures of intention, behavioral, normative, and control beliefs and a one-month follow-up of…
Understanding Nonsmoking in African American and Caucasian College Students
Few studies have considered whether psychological determinants of nonsmoking among college students vary by ethnicity. The authors tested the theory of planned behavior (TPB) to explain differences in nonsmoking intentions of 238 African American and 197 Caucasian college students who completed an in-class TPB questionnaire and a smoking assessment 1 week later. After removing 35 students who reported smoking at the baseline assessment, regressio…
