This research line focuses
on behavioral and psychosocial aspects of physical activity, nutrition, and
obesity/weight control, in intervention and population studies in adults. Key
research topics include correlates, moderators, and mediators of i) behavior and
behavior change, ii) weight loss and weight maintenance, or iii) positive
psychological outcomes in obesity/weight control. Another research focus is the
use of Self-Determination Theory to understand and influence motivational and
self-regulatory aspects of weight control behaviors, especially physical
activity, through effective interventions.
Current Research Topics
- Predictors of success in
weight loss and weight loss maintenance
- Psychological predictors
(moderators, mediators) of successful weight control
- Exercise / physical activity
and exercise motivation as predictors of weight loss and
maintenance
- The National (Portuguese)
Weight Control Registry: characteristics of successful weight
loss maintainers
- Self-determination theory,
self-motivation, and
health behavior change
- Using self-determination
theory to promote autonomous self-regulation of exercise, eating
behavior, and weight control
- Self-determination
theory-based mediators of exercise/physical activity and eating
behavior
- The role of
self-determination in body image, psychological health, and
subjective well-being in overweight and obese persons
- Interactions among physical
activity, eating behavior, body image, and body weight
- The association of
physical activity with eating self-regulation during weight
management and in the population
- The impact of body image and
subjective well-being on body weight control, physical
activity/exercise, eating and exercise self-regulation
- Other topics of interest:
- Using Ecological Momentary
Assessment (EMA) to study health behavior change
- Measuring exercise / physical
activity in overweight and obese persons
