Weight and health locus of control beliefs in an australian community sample

Association between nutrition self-efficacy, health locus of control and food choice motives in consumers in nine European countries

We investigated associations between food choice motives and psychological determinants of dietary health behaviour change (nutrition self-efficacy, NS-E, and health locus of control, HLoC) among 9381 participants (18-65 years, 49.4% females) from nine European countries. Price was the highest rated food choice motive. Higher importance of all motives was associated with higher NS-E and with higher Internal HLoC. Relationships between food choice motives and External HLoC were also in the expected direction in showing negative associations with Health, Natural Content, Weight Control, Mood and Sensory Appeal. Higher External HLoC was also associated with perceived greater importance of 'external' motives Ethical Concern, Familiarity and Convenience. Relationships between External HLoC and food choice motives were not all in the expected direction. Price was unrelated to External HLoC. Females rated the importance of all motives higher than males. People with less education ascribed greater importance to Price in motivating food choices. Together, these findings imply that self-efficacy and health locus of control should be considered along with motivations for food choice in dietary health promotion.

Examining the relationship between weight controllability beliefs and eating behaviors: The role of internalized weight stigma and BMI

Body weight is often viewed as personally controllable. This belief, however, ignores the complex etiology of body weight. While such attributions of personal willpower may help some individuals regulate their eating patterns, they have also been associated with increased internalized weight stigma which, itself, is associated with more disinhibited eating. The current investigation aimed to examine how internalized weight stigma, along with BMI, may explain the effect of weight controllability beliefs on disparate dietary behaviors. A community sample of 2702 U.S. adults completed an online survey about their weight controllability beliefs, eating behaviors, and internalized weight stigma, as well as demographic items and self-reported BMI. Results showed that greater weight controllability beliefs were positively related to both more restricted eating, β = 0.135, p < .001, and more disinhibited eating, β = 0.123, p < .001. This ironic effect was partially explained by increased internalized weight stigma. Moreover, BMI moderated the relationship, such that individuals with lower weights demonstrated stronger effects for two of the three eating outcomes than those with higher weights. These findings advance our understanding of the relationship between attributions of personal control for body weight and subsequent health behaviors, and further underscore the need to target internalized weight stigma in dietary interventions.

General Self-Efficacy and Body Weight: The Role of Race and Gender

Overweight and obesity have become a prominent concern for policymakers, the Surgeon General, scholars, and for work organizations. The estimated annual cost of obesity in terms of lost productivity is in the tens of billions of dollars, and the estimated annual medical cost of obesity is in the hundreds of millions of dollars. Psychologists have become increasingly interested in issues related to body weight, such as ways to help people reduce body weight. The aims of our study are twofold. First, based on social cognitive theory, we offer the first study of the relationship between general self-efficacy (GSE) and body weight based on a large, representative sample. Second, we also offer an understanding of the role of race and gender as potential boundary conditions of this relationship. Findings indicate that race moderates the relationship between GSE and body weight (both BMI and perceived weight) such that this relationship is positive for Blacks but negative for Whites. Gender did not moderate the relationship between GSE and body weight. These results suggest that body weight is unrelated to general self-efficacy in the population writ large and that body weight is differentially related to self-efficacy based on race but not gender.

Weight Goals, Perceptions, and Practices Among Hispanic and Anglo College Females

This study explored the weight management practices, rates overweight and obesity, perceptions of body weight, and weight management goals in a large sample ( N = 467) of Hispanic ( n = 421) and Anglo ( n = 46) female college students on the U.S.-Mexico border. Women self-reported their height and weight, weight perceptions, and weight management goals and practices. About one third of the sample was overweight and many reported using weight management methods, most notably exercise and restraint dieting. The only significant difference between Anglos and Hispanics was for exercise, where Hispanics reported exercising more frequently. Although most weight control practices positively intercorrelated, exercise and restraint dieting were negatively correlated. Path analyses showed that weight perceptions and weight management goals mediated associations between body mass index and weight management practices. Results suggest that weight management interventions emphasize increasing exercise and controlling calories, together, as a means to achieve healthy weight.

Multidimensional Health Locus of Control: Comments on the Construct and its Measurement

In the present commentary, the theoretical construct of Multidimensional Health Locus of Control (MHLC) is described and evaluated in terms of its contributions to health psychology. This concept is compared to other control beliefs, in particular to perceived self-efficacy. It is argued that MHLC has supplied health psychology with essential insights and has offered a great deal of intellectual stimulation. Nevertheless, for some applications, different constructs might be more promising, in particular when it comes to predicting health behavior change. MHLC measurement, specifically its factorial structure, its proximity to health outcomes and health behaviors and its cultural sensitivity are addressed. Further refinement of the instrument is recommended, and the range of promising applications needs to be clearly defined.

Control Constructs: Do They Mediate the Relation between Educational Attainment and Health Behaviour?

Health promoting behaviours seem to be more prevalent among people with higher socio-economic status (SES). The main purpose of this article was to study (a) the relationship between education (as a dimension of SES) and intention and health behaviour (fruit/vegetable consumption), (b) the relationship between education and control conceptualizations (health locus of control (HLC), responseefficacy and self-efficacy) and (c) to what extent the relationship between education and intention/health behaviour (fruit/vegetable consumption) was mediated through different control beliefs. The results showed that women with higher education had higher intentions to consume fruit/vegetables and consumed fruit/vegetables more frequently. Higher education was associated with higher selfefficacy and response-efficacy beliefs and less belief in HLCchance. These control beliefs partly mediated the education–intention/behaviour relationship.

Health-related locus of control and health behaviour among university students in North Rhine Westphalia, Germany

Background

Health control beliefs were postulated to be associated with health behaviour. However, the results of studies assessing these associations suggest that they might not be universal. Among young adults associations have been reported, but the evidence is limited. The objective of this analysis was to re-examine these associations in a sample of university students in Germany.

Findings

Data from a multicentre cross-sectional study among university students in North Rhine-Westphalia, Germany was used (N=3,306). The Multidimensional Health Locus of Control Scale with three dimensions (one internal and two external) and six aspects of health behaviour (smoking habits, alcohol use, drug consumption, being over-/ or underweight, physical activity, and importance of healthy nutrition) were evaluated. Students with stronger internal locus of control paid more attention to healthy nutrition and displayed a higher level of physical activity. Individuals with a stronger belief in health professionals were less likely to use drugs and paid more attention to healthy nutrition. Furthermore, higher scores in the second external locus of control dimension (beliefs in luck or chance) were associated with a higher likelihood of current smoking, lower physical activity and less attention to healthy nutrition.

Conclusions

Students engaged more strongly in unhealthy behaviour if they believed that luck determines health. In contrast, believing in having control over one’s own health was associated with more healthy behaviour. These findings support the need to consider health control beliefs while designing preventive strategies in this specific population.

Physical and psychosocial factors associated with health-promoting behaviors among elderly Chinese with type-2 diabetes

This study explored how physical and psychosocial factors influenced the practice of health-promoting behaviors among elderly Chinese patients with type-2 diabetes. Individual structured interviews were conducted with 191 elderly Chinese attending an outpatient clinic in Hong Kong. Results showed that demographic and illness characteristics were unrelated to health practices. Participants were more likely to engage in health-promoting behaviors when they were physically well, valued their health, were confident of practicing the behaviors and viewed their illness as controllable by both doctors and themselves. The above factors exerted their respective main effects, instead of interaction effects, in predicting health practices.

Gender differences in implicit weight identity

OBJECTIVE

This study examined gender differences in explicit and implicit attitudes toward overweight and explicit and implicit weight identity.

METHOD

Normal weight women (n=22) and men (n=20) and overweight women (n=20) and men (n=21) completed the Implicit Association Test and portions of the Eating Disorders Questionnaire.

RESULTS

Although explicit and implicit anti-fat attitudes were ubiquitous, gender differences emerged for weight identity. Both men and women provided accurate explicit appraisals of their weight status. However, men implicitly identified themselves as light regardless of actual weight status. Women's implicit weight identity was associated with their actual weight status, explicit weight appraisal, and implicit self-esteem.

DISCUSSION

These findings may provide additional insight into why men are underrepresented among those seeking weight loss and why women are at increased risk for developing eating disorders.
