Clinical Obesity
|June 28, 2019
Summary
People with obesity often intend to eat less and healthier to control weight, but struggle with execution. This highlights challenges in self-control-focused weight management treatments.
Area of Science:
- Behavioral Science
- Obesity Research
- Nutritional Psychology
Background:
- Cognitive restraint (CR) is the intention to control food intake for weight management.
- Existing CR measurement tools may assess actual control rather than intention.
- Understanding CR in relation to weight status is crucial for effective interventions.
Purpose of the Study:
- To examine the relationship between weight status and cognitive restraint in a French population.
- To determine if CR is more prevalent in individuals with obesity compared to other weight categories.
- To investigate whether individuals with obesity are less restrained eaters.
Main Methods:
- Cross-sectional study of 507 French adults (aged 18-78).
- Online questionnaire assessing cognitive restraint using a numeric scale due to validity concerns with existing tools.
- Data collected from a general French population sample.
Main Results:
- Individuals with obesity reported a higher intention to eat less, eat healthier, and reduce sugar/fat intake compared to other weight groups.
- Despite intentions, individuals with obesity did not demonstrate successful control over their eating behaviors.
- The study identified potential content validity issues with common CR measurement questionnaires.
Conclusions:
- Obesity is associated with a strong intention for dietary control, but not necessarily successful execution.
- Current treatments focusing solely on increasing self-control may be insufficient for individuals with obesity.
- Further research is needed to establish a scientific consensus on the definition and measurement of CR for effective treatment development.

65.7K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

01:29Reliability and Validity
13.8K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

02:16Stereotype Content Model
15.4K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

00:57Weighted Mean
6.2K
While taking the arithmetic, geometric, or harmonic mean of a sample data set, equal importance is assigned to all the data points. However, all the values may not always be equally important in some data sets. An intrinsic bias might make it more important to give more weightage to specific values over others.
For example, consider the number of goals scored in the matches of a tournament. While computing the average number of goals scored in the tournament, it may be more important to...

The perpendicular-axis theorem states that the moment of inertia of a planar object about an axis perpendicular to its plane is equal to the sum of the moments of inertia about two mutually perpendicular concurrent axes lying in the plane of the body.
Consider a circular disc of mass M and radius R lying along an x-y plane. The origin lies at the center of the disc, and the z-axis is perpendicular to the disc's plane. All three axes coincide at the disc's center. The moment of inertia of this...
