Validity
Ability of test to measure accurately, with minimal error, a specific physical fitness component
Validity coefficient (r)
Relationship between predicted score and reference score
- Close to 1 = valid
Line of best fit
Regression line for relationship between measured and predicted scores
Standard error of estimate (SEE)
How far away the predicted are from the line of best fit - want to be small
Sensitivity
probability of correctly identifying individuals with a risk (low false negative)
Specificity
Probability of correctly identifying individuals without a risk - low false positive
Reliability
Consistent and stable over time
Objectivity
Intertester reliability (can be administered by different people and still produces consistent results)
Line of identity
Line that represents a forced perfect relationship between reference value and predicted value
- Values above the line underestimate
- Values below the line overestimate
Bland-Altman plot with 95% limits
How many participants are needed for every variable in a predictive test
20-40 participants
What determines behaviour?
Likelihood of a person adopting a healthy behaviour = motivating factors - inhibiting factors
What is a theory and why do we use them
Cognitive-based theories of behaviour
Social cognitive theory and self-determination theory
Stage based theories of behaviour
Transtheoretical model and health action process approach
Social Cognitive Theory
Cognitive influences in SCT
Environmental influences in SCT
Behavioral influences of SCT
Self-efficacy
One’s belief in their ability to succeed in specific situations
Outcome expectations
One’s belief in the positive and negative consequences that will occur from engaging in the specific behaviour
Self-regulation
Skills/tools involved with controlling one’s behavior to pursue long term goals
Barriers and facilitators
Factors which help or hinder performing a bahaviour
How do we increase self-efficacy?
