Determinants of physical activity in newly diagnosed obstructive sleep apnea patients: testing the health action process approach.

This study aims to identify the determinants associated with physical activity (PA) behavior in newly diagnosed obstructive sleep apnea (OSA) patients by applying the Health Action Process Approach (HAPA) with a longitudinal design. Anthropometric and clinical (OSA severity, subjective somnolence, use of continuous positive airway pressure (CPAP)) variables, the determinants of physical activity specified in the HAPA (motivational self-efficacy, outcome expectancies, risk perception, intention, maintenance self-efficacy, action planning, coping planning, social support), as well as physical activity behavior were assessed using a longitudinal (T1 and T2) design in a sample of 57 OSA patients in routine care. Applying regression analyses, regarding the motivation phase, the amount of explained variance in intention was 77% and 39% of the variance in physical activity. In the motivational phase, motivational self-efficacy, risk perception and outcome expectancies were associated with intention. In the volitional phase, physical activity at T1 and social support (family) were related with physical activity at T2. In conclusion, the assumptions of HAPA were partially found in the context of newly diagnosed OSA patients. This study provided additional evidence regarding the role of motivational self-efficacy, outcome expectancies and risk perception during motivational phase, and highlighted the important role of social support from the family in the PA in this population.

Using interbrain synchrony to study teamwork: A systematic review and meta-analysis.

It has been proposed that interbrain synchrony (IBS) may help to elucidate the neural mechanisms underpinning teamwork. As hyperscanning studies have provided abundant findings on IBS in team environments, the current review aims to synthesize the findings of hyperscanning studies in a way that is relevant to the teamwork research. A systematic review was conducted. Included studies were classified according to the IPO (i.e. input, process, output) model of teamwork. Three multi-level meta-analyses were performed to quantify the associations between IBS and the three IPO variables. The methodology followed PRISMA guidelines and the protocol was pre-registered (https://osf.io/7h8sa/). Of the 229 studies, 41 were included, representing 1326 teams. The three meta-analyses found statistically significant positive effects, indicating a positive association between IBS and the three IPO teamwork variables. This study provides evidence that IBS is a relevant measure of the teamwork process and argues for the continued use of IBS to study teamwork.

An explanatory model of authentic leadership, flourishing and work-family balance of nurses in French hospitals.

PURPOSE: This study aims to investigate the relationship between a positive leadership style [i.e. authentic leadership (AL)] and nurses' psychological health (i.e. nurses' flourishing and satisfaction with work-family balance), including psychological capital (PsyCap) as a mediational variable. DESIGN/METHODOLOGY/APPROACH: A cross-sectional study was conducted with a self-report questionnaire including 1,076 nurses from public and private hospitals in France. FINDINGS: Structural equation modeling results revealed that AL is related to nurses' flourishing and satisfaction with work-family balance and that PsyCap acted as a partial mediator between this leadership style and positive outcomes. PRACTICAL IMPLICATIONS: This research indicated that hospitals can enhance nurses' psychological health not only in their work but also in their lives in general by improving leaders' authentic management style and developing PsyCap (e.g. staffing, training and development). ORIGINALITY/VALUE: An original feature of this paper concerns its focus on the mediating role of PsyCap in the relationship between AL and these positive outcomes. Moreover, this study underlined the influence of leadership style on nurses' psychological health beyond occupational health. The research makes a valuable contribution to the existing AL literature by establishing a new explanatory model of AL and nurses' psychological health in the French context. It also highlights the interest in developing this leadership style in health-care settings.

Transformational leadership and creativity in sport: Examining the mediating role of support for innovation.

Understanding how and when transformational leadership is related to followers' perceptions is an important issue. The present study aims to investigate the potential mediating role of support for innovation in the relationship between transformational leadership and creativity in team sports. We also propose that players' team tenure could moderate this relationship.A cross-sectional design was used. Athletes (Nplayers = 447, Nteam = 45, Mage = 22.12; SD = 5.09) completed questionnaires assessing transformational leadership, support for innovation and creativity.Support for innovation mediated the positive relationship between inspirational motivation, intellectual stimulation and high-performance expectations as exogenous variables and creativity as a dependent variable. Moreover, the relationship between intellectual stimulation and creativity was significantly weaker when players' team tenure was high. The relationship between transformational leadership behaviours (inspirational motivation, intellectual stimulation, and high-performance expectations) and support for innovation was stronger when players' team tenure was low.The current study provides the first evidence of a relationship between transformational leadership and creativity through support for innovation in team sports. This study is also the first to have provided evidence of the role of players' team tenure in those mediational relationships. Theoretical and practical implications are discussed.

How Sedentary Are University Students? A Systematic Review and Meta-Analysis.

Accumulating high volumes of sedentary behaviour is a risk factor for multiple negative health-related outcomes. The objective of this review was to synthesise the evidence on the levels of sedentary behaviour in university students. Screened records from 13 databases were included if (i) published after 2007 and (ii) reported on university students' amount of total or domain-specific sedentary behaviour. Sub-group and meta-regression analyses were conducted to investigate potential sources of heterogeneity (moderators). A total of 125 studies met the inclusion criteria. Most studies were cross-sectional (84%) and reported screen time (61%) or total sedentary time (39%). Self-reported data indicated that university students spend 7.29 h per day being sedentary. The levels of total sedentary behaviour were significantly higher when measured with accelerometers (M = 9.82 h per day). Computer use presented significantly higher prevalence over other modalities of screen time. Among the explored factors (i.e. countries' income, age, gender, and study's publication date), only publication date significantly moderated sedentary behaviour. Results suggest that a considerable proportion of university students (i) engage in higher levels of sedentary time compared to the general young adult population and (ii) accumulate levels of sedentary time that have been associated with an increased risk for detrimental health outcomes. In addition, meta-regression analyses suggest that sedentary time has increased over the last 10-year period among university students. These findings may inform future initiatives and policies targeting university students' sedentary behaviour. Further research is needed to identify the factors moderating sedentary behaviour in the university setting.

Better Understanding the Workers' Retirement Decision Attitudes: Development and Validation of a New Measure.

The aim of the present research was to develop a measure that could be used in future research for in-depth study of the psychological management of retirement. We report the results of six studies involving 1,898 French workers designed to develop and assess the psychometric properties of a new instrument named the Workers' Retirement Motivations Inventory (WRMI) using the push pull anti-push anti-pull model. The items were constructed based on a review of the relevant psychological literature and face-to-face interviews with senior workers. A combined method of exploratory structural equations modeling and confirmatory factor analysis (CFA) was employed and provided evidence for validating this structure of the inventory. The WRMI showed consistency of the four-factor structure across different samples, internal consistency, test-retest reliability, and predictive validity of workers' plans for retirement. Implications of these findings and avenues for counseling activities and future research are discussed.

Correlates of sedentary behaviour in university students: A systematic review.

High levels of sedentary behaviour are associated with negative health-related outcomes. However, there is limited evidence on the variables influencing sedentary behaviour in university students. The aim of this systematic review was to identify the intrapersonal, interpersonal, environmental, and time correlates of sedentary behaviour in university students. Records from 12 electronic databases were screened by two independent reviewers. Inclusion criteria included: (i) peer-reviewed articles written in English, Spanish, or French; (ii) studies including undergraduate or postgraduate university students; (iii) studies reporting on the association between sedentary behaviour and at least one variable. The protocol is registered in PROSPERO (CRD42017074198). A total of 126 studies published between 1994 and 2017 met the inclusion criteria. The primary measure of sedentary behaviour was self-reported screen time (61%), followed by total sitting time (28%). Most studies were cross-sectional (86%). After excluding high risk of bias studies (58%), only three intrapersonal variables were sufficiently investigated (≥4) to determine an association with sedentary behaviour: physical activity (negative association with sitting time), obesity markers (indeterminate associations with TV viewing), and gender - female (null associations with total sitting time and screen time). Overall, most of the reported correlates of sedentary behaviour were intrapersonal, non-modifiable factors. Further research on modifiable correlates covering all socio-ecologic levels is required to inform future intervention development. In addition, longitudinal studies are needed to enable the identification of determinants. Improvements in designing and reporting future studies are recommended to help strengthen the available evidence and facilitate future reviewing efforts.

Physical Activity and Personality Development over Twenty Years: Evidence from Three Longitudinal Samples.

A physically inactive lifestyle is associated with maladaptive patterns of personality development over relatively short follow-up periods. The present study extends existing research by examining whether this association persists over 20 years. Participants (total N = 8,723) were drawn from the Wisconsin Longitudinal Study Graduates and Siblings samples and the Midlife in the United States Study. Controlling for demographic factors and disease burden, baseline physical inactivity was related to steeper declines in conscientiousness in all three samples and a meta-analysis (ß=-.06). The meta-analysis further showed that lower physical activity was associated with declines in openness (ß=-.05), extraversion (ß=-.03), and agreeableness (ß=-.03). These findings provide evidence that a physically inactive lifestyle is associated with long-term detrimental personality trajectories.

A scoping review on interventions to promote physical activity among adults with disabilities.

BACKGROUND: Despite the strong evidence that physical activity (PA) is a key determinant of health, there is limited knowledge on the content and outcomes of PA promotion interventions among individuals with disabilities. OBJECTIVE: To conduct a scoping review in order to examine the published literature on PA promotion interventions among adults with disabilities. METHODS: A scoping review following the methodological framework provided by Arksey and O'Malley used electronic databases (MEDLINE, PsycINFO, and CINAHL), reference lists, and journals to locate studies. Inclusion criteria were based on study aim, outcome measures, and a disability definition by the WHO International Classification of Functioning, Disability and Health. The Behavior Change Techniques Taxonomy version 1 and Furlan and collaborators' risk of bias assessment were utilized during the data charting stage. RESULTS: Thirty-eight articles met the inclusion criteria. Most of the studies (70%) reported a significant increase in PA behavior immediately following intervention. However, less than half of the studies (46%) examined the maintenance of pre-/post-test differences. The number of identified behavior change techniques was significantly higher for successful PA promotion interventions than for interventions with no effects on PA. Approximately one-third of studies (32%) were rated as having a high risk of bias. CONCLUSIONS: Although findings support the idea that PA promotion interventions produce positive changes in PA behavior for a variety of disability conditions, risk of bias assessment calls for prudence. There are opportunities for continued development of the area of PA promotion among individuals with disabilities through systematic reviews and meta-analyses.

Sensory functioning and personality development among older adults.

Deficits in sensory functioning, such as poor vision and hearing, take a significant toll on quality of life. Little is known, however, about their relation with personality development across adulthood. This study examined whether baseline and change in vision and hearing were associated with personality change over a 4-year period. Participants (N = 7,471; Mage = 66.89; 59% women) were drawn from the Health and Retirement Study. They provided data on vision, hearing, and personality both at baseline and 4 years later. Poor vision and hearing at baseline and declines in vision and hearing over time were independently related to steeper declines in extraversion, agreeableness, openness, and conscientiousness, and less decline in neuroticism, controlling for demographic factors, disease burden, and depressive symptoms. Sensory functioning was generally a stronger predictor of personality change than disease burden or depressive symptoms. Consistent with evidence that poor and worsening sensory functions compromise individuals' interactions with the social and physical environment, this study found deficits in hearing and vision were also associated with maladaptive personality trajectories in older adults.

Athletes' perceptions of role ambiguity and coaching competency in sport teams: a multilevel analysis.

The purpose of this study was to examine the relationship between athletes' perceptions of role ambiguity and two theoretically derived dimensions of coaching competency (i.e., game strategy and technique competencies). A total of 243 players from 26 teams representing various interdependent sports completed French versions of the Role Ambiguity Scale and the Coaching Competency Scale. Multilevel analyses supported the existence of relationships between the four dimensions of role ambiguity and the two dimensions of coaching competency at both individual and team levels. When the levels were considered jointly, athletes perceiving greater ambiguity in their role in both offensive and defensive contexts were more critical of their coach's capacities to lead their team during competitions and to diagnose or formulate instructions during training sessions. The results also indicated that the dimension of scope of responsibilities was the main contributor to the relationship with coaching competency at an individual level, whereas role evaluation was the main contributor to this relationship at a group level. Findings are discussed in relation to the role episode model, the role ambiguity dimensions involved in the relationships according to the level of analysis considered, and the salience of ambiguity perceptions in the offensive context.
