Variables that explain disordered eating behaviors among women: the mediating role of body dissatisfaction.

Purpose: To analyze the role of body dissatisfaction in the relationships of sociocultural influences, depression, and anxiety with disordered eating behaviors (DEB) in a sample of female Mexican university students.

Methods: A nonrandom sample of 526 female Mexican university students aged 18 to 25 years completed the Questionnaire of Influence on the Aesthetic Model of Body Shape (CIMEC-26), the Hospital Anxiety and Depression Scale (HADS), the Body Shape Questionnaire (BSQ-8D) and the Eating Attitudes Test (EAT-26).

Results: Through the mean model (χ/df (5, n = 526) = 7.

Psychosocial factors associated with the risk of developing psychosis in a Mexican general population sample.

Epidemiological evidence has linked an array of sociodemographic and psychosocial factors with an increased risk of developing psychosis. However, research in samples from low- and middle-income countries is still scarce. This study used a Mexican sample to explore (i) sociodemographic and psychosocial differences between individuals with and without a positive screen for Clinical High-Risk for psychosis (CHR), and (ii) sociodemographic and psychosocial factors associated with screening positive for CHR.

Emotional intelligence subdimensions as moderators in the association between body dissatisfaction and symptoms of eating disorders among female Mexican adolescents.

Objective: Strong empirical research has shown a relationship between body dissatisfaction and symptoms of eating disorders (ED) and the direct and combined influence of emotional factors and dimensions of emotional intelligence (EI) on ED symptoms. However, whether these emotional variables and competencies moderate the well-established relationship between body dissatisfaction and ED symptomatology has not yet been tested. Neither have studies of this nature been performed among high at-risk populations such as Mexican female adolescents.

The moderating role of emotional intelligence in the link between self-esteem and symptoms of eating disorders.

Objective: This research aimed to explore the moderating role of emotional intelligence (EI) in the relationship between self-esteem and eating disorders (ED) symptomatology.

Method: A battery of online questionnaires was administered to a sample of 516 adults including university students and a community population. The sample, age range of 18-77 years (X = 38.

Content validity of a psychological e-health program of self-control and motivation for adults with excess weight.

Excess weight requires multidisciplinary treatment, including psychology in face-to-face and e-health interventions. The need to analyse interventions' content validity has become evident. The objective is to assess content validity of a psychological e-health program of self-control and motivation for adults with excess weight.

Evaluating different versions of the Body Shape Questionnaire and invariance across age in Mexican women.

Purpose: To analyze the factorial structure of the eight short versions of the Body Shape Questionnaire (BSQ) and analyze the factorial invariance of the best model, its convergent validity and its internal consistency in three age groups of Mexican women.

Methods: Women attending middle school (n = 261), high school (n = 245) and university (n = 296) participated in the study; their average age was 16.52 years (SD = 2.

Health-related quality-of-life model in adolescents with different body composition.

The purpose of the present study was to develop and evaluate a causal model of health-related quality of life (HRQoL) in adolescents with different body composition. The participants were 209 adolescents (107 women and 102 men) ranging from 10 to 15 years of age. A model based on that proposed by Wilson and Cleary (JAMA 273(1):59-65, 1995) was elaborated.

Psychometric evaluation of the muscle appearance satisfaction scale in a Mexican male sample.

Purpose: The purpose of this study was to determine whether the muscle appearance satisfaction scale (MASS) shows acceptable psychometric properties in Mexican bodybuilders.

Methods: A total of 258 Mexican male bodybuilders were recruited. Two self-report questionnaires, including the MASS and drive for muscularity scale (DMS), were administered.

Perceptions of overweight in US and global cultures.

We explored the hypothesis that perceptions of overweight vary in accord with the prevalence of overweight in specific populations. The present study investigated this relationship in samples from diverse groups in the US and four other countries. The perceptual threshold for overweight is the scalar point at which individuals determine the transition from normal to overweight.

Psychometric properties of the drive for muscularity scale in Mexican males.

This study refers to the evaluation of the psychometric properties of the Drive for Muscularity Scale among Mexican population. The exploratory factor analysis was carried out with 369 university males (mean age = 20.93 years).

[Body image and eating disorders].

Objective: Assessing the association of age and weight with internalisation of the ideal of being thin, bodily dissatisfaction and eating disorder symptoms amongst three groups of females: teenage, young and adult women.

Material And Methods: 145 females participated, ranging in age from 12 to 46, who answered four self-reporting questionnaires aimed at measuring symptoms of anorexia nervosa, bulimia nervosa, the ideal of being thin and bodily dissatisfaction. The participants' weight and height were also recorded for calculating their body mass index.

A two-stage epidemiologic study on prevalence of eating disorders in female university students in Mexico.

Objective: This study investigated the prevalence of eating disorders (ED) in women.

Method: Two samples of university students (1995, n = 522; 2002, n = 880) completed the Eating Attitudes Test and the Bulimia Test (BULIT; Stage 1). During Stage 2, the women that exceeded the cut-off point of one or both questionnaires and a random sample of women that did not exceed the cut-off point were interviewed.
