1. SCOFF questionnaire
: Basic yet reliable set of five questions that help assesswhether 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?
2. Scientific Method
: The process of formulating explanations about the naturalworld 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
,3. Evidence-Based Practice
: 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.
4. Prediction
: An expected outcome generated from a hypothesis
5. Theory
: A hypothesis or set of hypotheses for which a large body of high-qualityevidence has
been accumulated.
6. Hierarchy of Evidence
: 1. Systematic Reviews
2. Randomized Controlled Trials
3. Observational Research
4. Peer Reviews
5. Non-Peer-Reviewed Media, including anecdotes
7. Anecdote
, : an account of a person's experience or event
8. Uncontrolled Variable
: A variable in an experiment that a scientist makes noeffort to manipulate or account
for.
9. Primary Research
: Original research where scientists perform experiments andcollect data - this is in contrast
to secondary research where scientists analyze datathat has already been collected or
published elsewhere.
10. Observational Research
: Research in which a researcher observes ongoingbehaviors to determine correlation.
11. Correlation
: A relationship between two or more variables.
12. Randomized Control Trial (RCT)
: A type of scientific study/trial where par-ticipants 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 randomizedand a
control is used in an attempt to reduce potential bias in the trial.
13. Independent Variable
: The variable scientists manipulate in an experiment.
14. External Validity
: The ability to generalize the results of a study.
15. Systematic Review
: A review where scientists systematically gather all re-search on a topic and evaluate
it based on predefined criteria and rules.
16. Meta-Analysis
: A statistical analysis of a group of studies to assess the overallweight of the evidence.
17. Empirical
: Based on observation or experience.
