SCOFF questionnaire ✔✔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?
Scientific Method ✔✔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
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.
Prediction ✔✔An expected outcome generated from a hypothesis
Theory ✔✔A hypothesis or set of hypotheses for which a large body of high-quality evidence
has been accumulated.
Hierarchy of Evidence ✔✔1. Systematic Reviews
2. Randomized Controlled Trials
3. Observational Research
4. Peer Reviews
5. Non-Peer-Reviewed Media, including anecdotes
Anecdote ✔✔an account of a person's experience or event
,Uncontrolled Variable ✔✔A variable in an experiment that a scientist makes no effort to
manipulate or account for.
Primary Research ✔✔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.
Observational Research ✔✔Research in which a researcher observes ongoing behaviors to
determine correlation.
Correlation ✔✔A relationship between two or more variables.
Randomized Control Trial (RCT) ✔✔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.
Independent Variable ✔✔The variable scientists manipulate in an experiment.
, External Validity ✔✔The ability to generalize the results of a study.
Systematic Review ✔✔A review where scientists systematically gather all research on a topic
and evaluate it based on predefined criteria and rules.
Meta-Analysis ✔✔A statistical analysis of a group of studies to assess the overall weight of the
evidence.
Empirical ✔✔Based on observation or experience.
Test-Retest Reliability ✔✔The ability to get similar results when something is measured under
the same conditions.
Reliability ✔✔The consistency of a measure.
Validity ✔✔The assessment of whether a tool is measuring what it is supposed to measure.
