Unformatted text preview: KIN 448: EXAM 3 STUDY GUIDE 1. What is a determinant and why do we study determinants? A determinant is a variable that correlates with physical activity behavior. A determinant should have reproducible association, be used for prediction, and be modifiable. Shows associations, NOT a cause-and-effect relationship Reproducible association variable is repeatedly seen, reliable; shows us that it is really important Prediction Measuring now and seeing if it affects physical activity or inactivity in the future Modifiable Want to be able to change it; tells us who is most in need to target We study determinants to identify inactive segments of society, discover modifiable variables that can be targeted by well-designed interventions, identify determinants in special populations for tailored interventions, and guide policy formation Determine: who is in need, how to develop a program, and guide policy! 2. What are the six categories of determinants? What are specific examples of determinants within each category? Of the determinants, which is best/least beneficial as a target for changing physical activity? Of the determinants, which is most beneficial for informing public policy formation? Of the determinants, which category is most important for understanding who should be targeted for changing physical activity? Six categories of determinants: 1. Demographic factors 2. Behavioral attributes and skills 3. Psychological, cognitive, and emotional factors 4. Social factors 5. Physical environmental factors 6. Physical activity characteristics Demographics Shows who to target: PA has a very strong inverse relationship with age and race/ethnicity (nonwhite). Education, male gender, and high SES are very important characteristics of physical activity Behavioral attributes History of past behavior (activity) is the strongest predictor of future behavior. Processes of change are strongly related to PA (things we can teach people scheduling, writing down workout schedule, bringing workout stuff with you, using reminders, setting goals, etc). Dietary habits also have a strong positive correlation with PA. Psychological, cognitive, and emotional factors LARGEST category of variables that are modifiable that we can target to increase PA . Strong positive correlationsself-efficacy, self- motivation, and enjoyment. Strong negative correlationslack of time, barriers, mood disturbance Social Relies on other people to produce change: social support from friends, family support, and physician influence all have strong positive correlations with physical activity. Although physician influence doesnt seem to work....
