A mixed method approach to evaluating eating-related psychopathologies in collegiate student-athletes.

Objective: To examine the presence of body image concerns, drive for muscularity, and disordered eating behaviors in collegiate student-athletes.

Participants: One hundred and one NCAA Division I student-athletes participated in Phase I; 15 of these also participated in Phase II.

Methods: This study employed a mixed method, sequential explanatory design.

Family history of obesity and the influence on physical activity and dietary adherence after bariatric surgery.

Background: The causes of obesity are multifactorial, with genetic, environmental, behavioural and societal contributions. These factors also affect adherence to diet and exercise after bariatric surgery. The objective of this study was to evaluate changes in perceived obesity-related stigma, exercise and dietary adherence perioperatively as well as what demographic factors most influence the magnitude of these changes.

What happens when you compare yourself to a model eating a cheeseburger? An experiment testing the impact of models promoting calorie-dense foods on beliefs about weight maintenance, body satisfaction, and purchase intent.

Background: Ads depicting models promoting calorie-dense foods and beverages are ubiquitous and no known research has examined their effects on consumers. Drawing from social comparison theory, we hypothesized that participants who viewed ads with models (versus without models) would be more likely to rate models and less likely to rate themselves as able to consume the calorie-dense foods regularly and still maintain their weight/shape. We also hypothesized that participants who viewed ads with models (versus without models) would report more body dissatisfaction and, consistent with consumer research, a greater intention to purchase the product.

Hop, skip... no! Explaining adolescent girls' disinclination for physical activity.

Purpose: This study aimed to develop and validate the Girls' Disinclination for Physical Activity Scale (G-DAS)and implement the scale along with an objective measure of physical activity (PA) in a longitudinal sample of adolescent girls.

Methods: Participants were non-Hispanic White girls who were assessed at ages 13 years (n=151) and 15 years (n=98). Girls completed the G-DAS and the Physical Activity Enjoyment Scale and wore an accelerometer for 7 days.

'I feel fat': weight-related stigma, body esteem, and BMI as predictors of perceived competence in physical activity.

Background: Efforts toward increasing participation in physical activity to prevent and treat overweight and obesity have as yet proved unsuccessful. Among the many barriers that discourage participation are weight-related stigmas. The primary purpose of this study was to explore the relationship between consciousnesses of weight-related stigma and perceived competence in physical activity.
