The Transtheoretical Model: Stages of Change

A

2) Contemplation (person has the intention to change target behaviour within 6 months).
3) Preparation (person plans to take action within a month or is already taking small steps to change behaviour).
4) Action (person is already making changes to behaviour which requires time and energy).
5) Maintenance (person has maintained new, healthier lifestyle for at least 6 months).
6) Termination (the new behaviour is adopted).

Criteria for Assessing Epidemiological Relationships

A

2) A greater response to a greater dose.
3) Consistency between different studies.
4) A temporal relationship (exposure occurred before symptoms).
5) A plausible mechanism (plausible reason why exposure causes symptoms).

Q

Confounding

A

Occurs when a (third or other) variable is associated with BOTH the exposure and outcome being studied. If this third variable is not taken into account, the relationship between the other 2 variables may be misinterpreted (the other variable is the actual reason for the symptom).

Q

Descriptive Studies

A

Do not test hypotheses. Describe how things are. Useful for public health agencies and health care planning.

90
Q

Analytical Studies

A

Tests a hypothesis. Look at outcome variable in relation to an exposure variable (tests hypothesis predicting an association).

91
Q

Types of Descriptive Studies

A

1) Case Study
2) Case Series

92
Q

Case Study

A

A study of one diseased individual providing a detailed description of an uncommon disease. Provides timely or rare information.

93
Q

Case Series

A

A study of multiple occurrences of unusual cases that have similar characteristics. Investigators can calculate the frequency of symptoms or characteristics of people with the disease.

94
Q

Cross-Sectional Studies

A

Survey in which the purpose of the analysis is to record associations between variables rather than merely to report frequencies of their occurrence.

95
Q

Cohort/Longitudinal/Perspective Studies

A

Select a population without disease(s) of interest and meeting any other desired criteria in terms of exposures and follow over a period of time to see what happens to its members.

96
Q

Case-Control/Retrospective Studies

A

The health profiles of the subjects in a particular “case” group (has a particular disease/outcome) are compared with those in a control group (without the disease/outcome) that has been selected to be as similar as possible to the “case” group (similar spread of ages, sex, etc.). Looking back in time to identify risk factors.

97
Q

Ecological Studies

A

Measures variables at the level of populations rather than individuals. Advantages: can provide powerful clues when comparing large populations and can use data that is already available, like government statistics. Disadvantages: can’t prove cause and effect (two factors must be studied in individuals).

98
Q

Sarcoma

A

A cancer that attacks tissues. Is a virus.

99
Q

Importance of Randomization

A

1) Advantage is that confounding factors are likely equally represented in each study group (like genetic characteristics).
2) Assuming no systematic error or bias (the only things that should differ between the 2 randomly assigned groups should be the intervention).

100
Q

Null Hypothesis

A

The hypothesis that the experimental treatment had no effect.
