Promoting self-control in overweight and obese children.

Background and objective: impulsiveness might affect the ability of an individual to plan meals, eat regularly, and resist impulses to enjoy foods that are high in fat and sugars in a particular way. The objective of the present study was to evaluate the effectiveness of a fading strategy regarding a reinforcer dimension to promote the development of self-control and decrease impulsive choice among 14 overweight and obese children. Material and methods: to meet this objective, an experimental procedure of choice behavior was used to evaluate the impulsivity and self-control choices influenced by four reinforcer dimensions on a computer: reinforcement rate, reinforcer quality, immediacy of the reinforcement, and response effort.

[Psychometric properties of the weight control perceived self-efficacy inventory in university students from the health area].

Introduction: empirical research shows that perceived self-efficacy is an important variable in maintaining and reducing weight. There are available instruments to measure perceived self-efficacy and its relation to obesity, but in Mexico it is still insufficient.

Objective: the purpose of the current research is to analyze the psychometric properties of the Mexican version of the self-efficacy inventory for weight control (SEI-WC) in university students in the health area.
