Question 1.
SCOFF questionnaire
ANSWER
Basic yet reliable set of five questions that help assess whether an eating disorder exists. Do you make yourself Sick because you feel uncomfortably full?
Do you worry that you have lost Control over how much you eat? Have you recently lost more than One stone (14 lbs) in a 3-month period? Do you believe
yourself to be Fat when others say you are too thin? Would you say that Food dominates your life?
Question 2.
Scientific Method
ANSWER
The process of formulating explanations about the natural world and testing those explanations with experiments and data.
1. Identify a Problem
2. Formulate a hypothesis
3. Design a study to test the hypothesis
4. Collect data
5. Discard or change the hypothesis OR continue testing
Question 3.
Evidence-Based Practice
ANSWER
A three-pronged approach to working with clients, which consists of making decisions based on the weight of the scientific evidence, field observations, and
individual client needs and preferences.
Question 4.
Prediction
ANSWER
An expected outcome generated from a hypothesis
Question 5.
Theory
ANSWER
A hypothesis or set of hypotheses for which a large body of high-quality evidence has been accumulated.
Question 6.
Hierarchy of Evidence
ANSWER
1. Systematic Reviews
2. Randomized Controlled Trials
3. Observational Research
4. Peer Reviews
5. Non-Peer-Reviewed Media, including anecdotes
, Question 7.
Anecdote
ANSWER
an account of a person's experience or event
Question 8.
Uncontrolled Variable
ANSWER
A variable in an experiment that a scientist makes no effort to manipulate or account for.
Question 9.
Primary Re-search
ANSWER
Original research where scientists perform experiments and collect data - this is in contrast to secondary research where scientists analyze data that has
already been collected or published elsewhere.
Question 10.
Observational Research
ANSWER
Research in which a researcher observes ongoing behaviors to determine correlation.
Question 11.
Correlation
ANSWER
A relationship between two or more variables.
Question 12.
Randomized Control Trial (RCT)
ANSWER
A type of scientific study/trial where participants are randomly assigned into different groups - one or more will be the intervention to be tested and one will
be the control group. Groups are randomized and a control is used in an attempt to reduce potential bias in the trial.
Question 13.
Independent Variable
ANSWER
The variable scientists manipulate in an experiment.
, Question 14.
External Validity
ANSWER
The ability to generalize the results of a study.
Question 15.
Systematic Re-view
ANSWER
A review where scientists systematically gather all research on a topic and evaluate it based on predefined criteria and rules.
Question 16.
Meta-Analysis
ANSWER
A statistical analysis of a group of studies to assess the overall weight of the evidence.
Question 17.
Empirical
ANSWER
Based on observation or experience.
Question 18.
Test-Retest Reliability
ANSWER
The ability to get similar results when something is measured under the same conditions.
Question 19.
Reliability
ANSWER
The consistency of a measure.
Question 20.
Validity
ANSWER
The assessment of whether a tool is measuring what it is supposed to measure.
Question 21.
Selection Bias
ANSWER
A sample of people under study is not representative of the larger population that scientists are looking to make inferences about.
, Question 22.
Retrospective
ANSWER
Describes a study that looks backward in time.
Question 23.
Recall Bias
ANSWER
The inability to accurately remember past behaviors.
Question 24.
Health
ANSWER
A state of complete physical, mental, and social well-being, not merely the absence of disease or infirmity.
Question 25.
Homeostasis
ANSWER
The tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.
Question 26.
Disease
ANSWER
A disorder of structure or function in a human, animal, or plant, especially one that produces specific signs or symptoms, affects a specific location, and is
not simply a direct result of physical injury.
Question 27.
Noncommunicable Disease
ANSWER
A noncommunicable disease (NCD) is a medical condition or disease that is not caused by infectious agents; it can refer to chronic diseases which last for
long periods of time and progress slowly.
Question 28.
Communicable Disease
ANSWER
Infectious diseases caused by microorganisms such as bacteria, viruses, parasites, and fungi that can be spread (directly or indirectly) from one person to
another.
