OBJECTIVE This longitudinal study investigated the interrelationship between children's weight status and level of gross motor coordination over time, taking baseline physical activity (PA) into account as a possible mediator. METHODS Baseline measurements were collected in 2517 children (5-13 years, 52.8% boys), including (1) body height and weight to(More)
Within Western society, many people have difficulties adequately regulating their eating behaviors and weight. Although the literature on eating regulation is vast, little attention has been given to motivational dynamics involved in eating regulation. Grounded in Self-Determination Theory (SDT), the present contribution aims to provide a motivational(More)
Adolescents are exposed to images depicting the thin or muscular ideal almost on a daily basis. When the body perfect ideal is adopted, adolescents are at increased risk for developing unhealthy and disordered eating behaviors. The aim of the current 3-wave longitudinal study among adolescents (N = 418; 54% girls) was to investigate whether different styles(More)
Based on Self-Determination Theory, this study aimed to gain further insight in the pathway from eating regulation to bulimic symptoms by (a) examining diet-specific need frustration as an intervening mechanism, (b) investigating the associations between different types of goals underlying eating regulation and diet-specific need frustration and bulimic(More)
OBJECTIVE The presence of nonsuicidal self-injury (NSSI) in eating-disordered (ED) patients is considered a complicating factor in treatment with a possibly adverse influence on patients' motivation to change. Using Self-Determination Theory as a guiding framework, we compared ED patients with and without NSSI in terms of their well-being and their motives(More)
Although abundant research has shown that self-critical perfectionism relates to binge eating symptoms, fewer studies have addressed the role of intervening processes that might explain why this is the case. Grounded in self-determination theory, we hypothesized that self-critical perfectionism would relate to an increased risk for binge eating symptoms(More)
OBJECTIVE Although several studies have established the beneficial effects of self-endorsed forms of motivation for lasting therapeutic change, the way patients with an eating disorder can be encouraged to volitionally pursue change has received less attention. On the basis of Self-Determination Theory, this longitudinal study addressed the role of an(More)

OBJECTIVE To investigate whether type of goals and motives underlying females' eating regulation are associated differentially with daily eating behaviours, dependent upon weight and age category. DESIGN 99 late adolescent female dieters (Mage = 18.94) and 98 adult female dieters (Mage = 45.06), 23.6% of which were overweight, completed a questionnaire(More)
