Self Efficacy Article 1 - Social Cognitive Theory and Nutrition Behavior
Terms in this set (13)
Why does self regulatory efficacy supersede performance self efficacy when it comes to diet and nutrition?
There has been a proliferation of foods that are cheaper and less healthy, individuals' confidence in preparing and eating healthier foods becomes less important
How do social support and outcome expectancies impact nutrition behaviors?
Perceived support from those that are important to you have been associated with better nutritional diet; outcome expectations, especially those related to satisfaction with the cost and taste of healthier foods, could contribute beyond self-efficacy to the understanding the nutrition behavior of a diverse sample of supermarket shoppers.
What was the purpose of this study?
To determine how SCT accounts for the nutritional content of food purchases and
consumption among adults in a health promotion study. To uncover potential approaches to nutrition behavior change in similar samples
Who were the participants of the study? What were the inclusion/exclusion criteria?
Participants - part of baptist and united methodists churches predominantly African American
Inclusion - regularly went to church
Exclusion - no member was excluded
Understand the social cognitive variables that were measured (summarized in table 1)
Social Support - perceived support from family for eating healthier
Self-regulatory Efficacy - Certainty of performance of behaviors to improve nutrition, across time and situations
Positive Outcome Expectations - Expectations of positive physical and self-evaluative outcomes
Negative Outcome Expectations - Expectations of negative physical, social, and self-evaluative outcomes
Self-regulaztion - Use in past 3 months of self-regulatory behaviors
How were nutrition behaviors quantified?
Family food shopping receipts and food frequency questionnaire
Understand the interaction between the variables.
All affected one another
Why do you think social support, SES, age and self-efficacy had an impact on self regulation? Think about examples for each individual variable.
Social support is important to help build up motivation in doing something and to be praised for changing behaviors. SES affects what the individual has access to with food. Self-efficacy could make the person feel confident in continuing with the process of good behavior.
Why do you think that positive outcome expectations failed to exert any total effect on nutrition (fat, fiber, fruits, and vegetables) while negative outcomes did have a significant total effect?
Negative outcomes will have a harsher effect due to the fact that it is a step back and can reduce your self-efficacy.
Considering the discussion, how did the person variables impact the nutrition behaviors of the sample?
- male - related to lower levels of fiber and fruits and vegetables; higher levels of fat
- Women had better nutrition because they exhibit greater self efficacy and were more likely to use self regulation strategies
- Old age was associate with healthier levels of fiber
- Higher SES was associated with healthier fiber; effects of SES on fiber were direct
- Social support made an important contribution to healthier nutrition; indirect through self efficacy
What are the limitations of the study? Why would the past behaviors of the sample be of interest?
- Research was nonexperimental
and the data correlational
- 3-month follow-back
period of the FFQ, however, overlapped the collection of
the Food Beliefs Survey
- Sample wasn't large enough
How can this data be used in an applied setting? (How can these variables guide a nutrition/diet intervention?)
Having outside influence could help influence in a positive outlook
Additional Question: Understand some of the proposed hypotheses (on the notes) for relationships between the variables.
Higher self efficacy and more positive outcome expectations lead to use of self regulatory behaviors to result in healthy eating maintenance
