Article
Background Both the close relationship processes and health model and the dyadic health influence model posit that beliefs about the relationship (e.g., relationship satisfaction) and influence strategies (e.g., social control) serve as mediators of health behavior change. The evidence for such mediation is limited. Purpose This study investigated...

Taxing sugar-sweetened beverages (SSB) is seen as a win–win situation for governments. It is argued that SSB taxes are relatively easy to implement from a practical perspective compared to for example other nutrition policies. However, the implementation of SSB taxation laws does not happen by itself. Therefore, this work examines implementation pr...

Background Policy frameworks focusing on policy implementation may vary in terms of their scope, included constructs, relationships between the constructs, and context factors. Although multiple policy implementation frameworks exist, the overarching synthesis characterizing differences between the frameworks is missing. This study investigated fra...
Article
Full-text available
Background Although multiple systematic reviews indicate that various determinants (barriers and facilitators) occur in the implementation processes of policies promoting healthy diet, physical activity (PA), and sedentary behavior (SB) reduction, the overarching synthesis of such reviews is missing. Applying the Consolidated Framework for Implemen...
Article
Objective: This study was designed to investigate the effects of collaborative, dyadic, and individual planning on moderate-to-vigorous physical activity (MVPA) in target person-partner dyads. Individual planning reflects an "I-for-me" planning of one person's behavior. Collaborative planning refers to joint planning of both dyad members' behavior...
Article
Full-text available
Background Patterns of protective health behaviors, such as handwashing and sanitizing during the COVID-19 pandemic, may be predicted by macro-level variables, such as regulations specified by public health policies. Health behavior patterns may also be predicted by micro-level variables, such as self-regulatory cognitions specified by health behav...

Background: The COVID-19 pandemic has affected people’s engagement in health behaviors, especially those that protect individuals from SARS-CoV-2 transmission, such as handwashing/sanitizing. Associations between the pandemic’s trajectory and engagement in the protective behavior of handwashing are unclear. This study investigated whether adherence...
Article
Introduction As early adolescents have limited capacities for self-regulating electronic media use (EMU), parental monitoring is needed. However, research has shown that parents do not exert much monitoring over their children's EMU. A theory-based approach may help to identify key predictors of parental monitoring and its effects on adolescents' E...
Article
Full-text available
Background There are two alternative mechanisms, elucidating the reciprocal relationship between self-efficacy and social support when explaining health outcomes: self-efficacy beliefs may operate as the establisher of social support (the cultivation model) or social support may enable the formation of self-efficacy beliefs (the enabling model). P...

Objective In dyadic planning a target person and a planning partner create plans for when, where, and how the target person will change a health-relevant behavior. Across 52 weeks, direct and indirect effects of a dyadic-planning intervention on moderate-to-vigorous physical activity (MVPA) and physical fitness in target persons and their partners...
Article
Full-text available
Purpose: Theoretical models, such as the transdiagnostic model of eating disorders highlight the role of cognitive factors (e.g., the way people perceive their bodies) and their associations with maladaptive weight management behaviors resulting in underweight. This paper aims at testing the indirect association of adolescent's body satisfaction a...
Article
Full-text available
Objective: Although there is substantial evidence corroborating the within-individual associations between depression, social support, moderate-to-vigorous physical activity (MVPA), and body mass, much less is known about across-individual associations. This study investigated the indirect associations between parental depression and objectively m...
Article
Full-text available
Background: Current evidence suggests that some of the most effective weight loss approaches are changes in dietary and physical activity behaviors through lifestyle modification programs. The Group Lifestyle Balance (GLB) program is a group-based behavior modification program aimed at changing diet and physical activity for weight loss. It was de...
Preprint
Background: The NIH-developed Diabetes Prevention Program (DPP) is successful in achieving clinically significant weight loss in individuals with overweight/obesity when delivered one-on-one. However, due to high cost of implementation, the long-term effectiveness remains limited. In response, a group-based version of the program, called the Nation...
Article
Full-text available
Background: Indicators of emotional processes (positive experiences with physical exercises) and functional processes (mobility) were previously found to be associated with positive cognitive resources (meaning in life), and the key outcome in the rehabilitation, namely physical quality of life (QOL). Yet, the mediating roles of such processes were...
Article
Objective: Based on the idea of the 'IKEA effect', assuming that individuals like self-created objects more than objects created by someone else, this study hypothesizes that parents' involvement of their children in meal planning and preparation is positively related to vegetable intake, mediated via liking vegetables. Design: Longitudinal obse...

Article
Objective: The interplay between parental and child food and physical activity aversion, briefly defined as fear or avoidance of novelty or breaking from routine, may explain such child behaviors as inadequate food consumption and physical activity. Two studies were conducted to investigate the associations between child and parental food and phys...
Article
Background: Existing evidence indicates that social support may enhance recipients' self-efficacy (enabling hypothesis) or that self-efficacy facilitates support receipt (cultivation hypothesis). However, less is known about the time-lagged support-self-efficacy relationship in couples. Our aim was to disentangle reciprocal interrelations among st...
Article
Full-text available
This study investigated if three maternal eating styles (emotional eating style, external eating style, and restrained eating style) predict respective eating styles in children. In particular, we tested if these associations are different in mother-daughter dyads, compared to mother-son dyads. Data were collected twice, at the baseline (Time 1; T1...
Article
Objectives: This study investigated reciprocal associations between meaning in life and physical quality of life (QOL) in the rehabilitation context. It was hypothesized that a higher level of meaning in life at Time 1 (T1) would predict better physical QOL at Time 2 (T2), and that better physical QOL (T1) would predict a higher level of meaning i...

Full-text available
Background Although the number of studies examining the relationships between sedentary behaviors (SB) and anxiety is growing, an overarching evidence, taking into account children, adolescents, and adults as well as different types of SB and different categories of anxiety outcomes, is still missing. Thus, this systematic review and meta-analysis...
Article
Full-text available
Background Socio-ecological models indicate that family, school, and community environment explains children’s physical activity and body weight. This study investigated whether parental perceptions of school/community-based physical activity (PA) promotion programs as well as parental and child perceptions of parental instrumental support for chil...
Article
Background: Although there is no doubt that indicators of physical activity (PA), negative and positive emotions are associated, the order in which they operate is not well-established. In this study, we investigated indirect associations between a negative emotions indicator (emotional symptoms of depression; henceforth: depression), a positive em...
Article
Objectives This study provides an insight into associations between: (1) parental and child perceptions of parental strategies restricting screen use among children, (2) child perceptions of the presence and availability of screen‐based equipment at home, (3) child sedentary screen use behaviours, and (4) child body fat. Design A prospective study...

Background: This longitudinal dyadic study used cross-lagged analyses to examine reciprocal patterns of associations between physical activity (PA) enjoyment and moderate-to-vigorous PA (MVPA) among children and their parents. Methods: At Time 1 (T1) 879 parent–child dyads provided their data. The follow-up (Time 2, T2) took place 7–8-months later....
Article
Full-text available
Background Body satisfaction is one of the key modifiable cognitive determinants of eating behaviours, physical activity, and body mass index (BMI). As the sociocultural models suggest, low body satisfaction may explain unhealthy eating and exercise behaviours. Importantly, body satisfaction levels and body areas that individuals focus on vary acro...

Failure to resist temptation may make people experience an action-control emotion of regret. We explored whether evoking regret after participants’ failure to attend physical exercise sessions would prompt them to undertake compensatory behaviors of different sorts. Physically active men and women (N = 133) were invited to attend a 6-session fitnes...
Article
Full-text available
Background: Most adolescents do not meet the recommendations for physical activity (PA) of at least 1 h per day. Individual planning (IP) interventions, including forming plans for when, where and how (action planning) to engage in a behavior, as well as the planning for how to deal with arising barriers (coping planning), are effective to enhance...
Article
Objective: This study investigated whether parental feeding practices, such as pressure to eat, permitting unhealthy food, and restriction of unhealthy food, predict children's body mass index (BMI) percentile or if children's BMI percentile predict parental feeding practices. Design: Longitudinal data were collected among 526 dyads of children...
Article
Objective The NIH‐developed Diabetes Prevention Program (DPP) is successful in achieving clinically significant weight loss in individuals with overweight/obesity when delivered one‐on‐one. The group‐based DPP is less effective, with average weight losses of only 3.5%. The objective of this study was to increase weight loss outcomes of the group‐ba...

Background: There has been a growing trend in the delivery of mental health treatment via technology (ie, electronic health, eHealth). However, engagement with eHealth interventions is a concern, and theoretically based research in this area is sparse. Factors that influence engagement are poorly understood, especially in trauma survivors with sym...
Article
Objectives In romantic relationships, partners can influence each other's health‐relevant behaviour by exerting negative social control (e.g., pressuring), however, with mixed success. To elucidate this phenomenon, we examined couples motivated to increase their physical activity and investigated the degree to which both partners exerted negative c...
Article
Full-text available
Objective: Parental practices that aim at increasing children's physical activity were found to be related to children's physical activity. So far, however, the association between these two sets of variables was studied without considering the moderating role of children's BMI z-score, which may determine the effectiveness of parental practices. T...
Article
Full-text available
Background: The uptake, implementation, and maintenance of effective interventions promoting physical activity (PA) and a healthy diet and the implementation of policies targeting these behaviors are processes not well understood. We aimed to gain a better understanding of what health promotion professionals and policy makers think are important f...
Article
Objectives Research explaining childhood obesity has been usually focused on cognitive and behavioral predictors assessed in parents only or in children only. In contrast, the dyadic approach allows to evaluate how parental and child predictors operate together to explain child physical activity (PA) and body fat. This study investigated relationsh...
