The association between implicit attitudes toward physical activity and physical activity behaviour: a systematic review and correlational meta-analysis.

As a result of recent calls to attend to the implicit processes that regulate health behaviours, the study of implicit attitudes and physical activity behaviour has grown rapidly in the past decade. The aim of this study was to summarise existing evidence on the extent to which implicit attitudes toward physical activity are associated with physical activity behaviour. A systematic literature review was performed to retrieve studies reporting both a measure of implicit attitudes and physical activity. For the meta-analysis, effect size (Pearson's r) were extracted from eligible studies or retrieved from authors. A total of 26 independent studies, and 55 effect sizes, were eligible. There was a small, significant, and positive correlation between implicit attitudes and physical activity, a finding replicated across multiple meta-analytical strategies with sensitivity analyses applied. This association was not significantly moderated by study design or objective, participants' age or other characteristics, or measures of implicit attitudes or physical activity. This meta-analysis provides evidence that implicit attitudes toward physical activity are positively associated with physical activity in adults to a small degree.

Passion and moral disengagement: Different pathways to political activism.

OBJECTIVE: Four studies examined the relationship between motivational imbalance-the degree to which a goal dominates other goals-and political activism. METHOD: Based on the dualistic model of passion (Vallerand, 2015) and recent theorizing on violent extremism (Kruglanski, Jasko, Chernikova, Dugas, & Webber, 2017), we predicted that obsessive passion (OP), which facilitates alternative goal suppression, would increase support for violent political behaviors. In contrast, we predicted that harmonious passion (HP), which facilitates the integration of multiple goal pursuits, would increase support for peaceful political behaviors. RESULTS: Study 1a demonstrated that OP for environmentalism was positively associated with moral disengagement, which in turn predicted violent behaviors. HP was positively associated with peaceful behaviors. Political activism among Democrats yielded similar findings in Study 1b. Study 2 replicated Studies 1a-1b using an implicit measure of moral disengagement. Study 3 replicated Studies 1-2 by demonstrating that experimentally inducing a harmonious (vs. obsessive) passion mindset indirectly reduced violent behaviors through the attenuation of moral disengagement while directly promoting peaceful behaviors. Study 4 conceptually replicated Studies 1-3 by experimentally manipulating moral disengagement. CONCLUSIONS: These results offer insights into the workings of radicalization and suggest theory-driven methods of reducing political violence.

[Functional genioplasty in growing patients]. / Génioplastie fonctionnelle chez les patients en croissance∗.

Objective - To evaluate the role of age as a moderator of bone regeneration patterns and symphysis remodeling after genioplasty. Method - Fifty-four patients who underwent genioplasty at the end of their orthodontic treatment were divided into three age groups: younger than 15 years at the time of surgery (group 1), 15 to 19 years (group 2), and 20 years or older (group 3). Twenty-three patients who did not accept genioplasty and had a follow-up radiograph two years after the end of their orthodontic treatment were used as a control group. Patients were evaluated at three time points: immediate preoperative (T1), immediate postoperative (T2) and two years postsurgery (T3). Results - The mean genial advancement at surgery was similar for the three age groups, but the extent of remodeling around the repositioned chin was greater in group 1, less in group 2, and still less in group 3. Symphysis thickness increased significantly during the two-years postsurgery interval for the three groups, and this increase was significantly greater in group 1 than in group 3. Remodeling above and behind the repositioned chin also was greater in the younger patients. This was related to greater vertical growth of the dentoalveolar process in the younger patients. There was no evidence of a deleterious effect on mandibular growth. Conclusion - The outcomes of forward-upward genioplasty include increased symphysis thickness, bone apposition above B point, and remodeling at the inferior border. When indications for this type of genioplasty are recognized, early surgical correction (before age 15) produces a better outcome in terms of bone remodeling.

Implementation intention and planning interventions in Health Psychology: Recommendations from the Synergy Expert Group for research and practice.

The current article details a position statement and recommendations for future research and practice on planning and implementation intentions in health contexts endorsed by the Synergy Expert Group. The group comprised world-leading researchers in health and social psychology and behavioural medicine who convened to discuss priority issues in planning interventions in health contexts and develop a set of recommendations for future research and practice. The expert group adopted a nominal groups approach and voting system to elicit and structure priority issues in planning interventions and implementation intentions research. Forty-two priority issues identified in initial discussions were further condensed to 18 key issues, including definitions of planning and implementation intentions and 17 priority research areas. Each issue was subjected to voting for consensus among group members and formed the basis of the position statement and recommendations. Specifically, the expert group endorsed statements and recommendations in the following areas: generic definition of planning and specific definition of implementation intentions, recommendations for better testing of mechanisms, guidance on testing the effects of moderators of planning interventions, recommendations on the social aspects of planning interventions, identification of the preconditions that moderate effectiveness of planning interventions and recommendations for research on how people use plans.
