SCOFF questionnaire
- correct 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?
Scientific Method
- correct 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
Evidence-Based Practice
- correct 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.
,Prediction
- correct answer An expected outcome generated from a hypothesis
Theory
- correct answer A hypothesis or set of hypotheses for which a large body of high-quality evidence has
been accumulated.
Hierarchy of Evidence
- correct answer 1. Systematic Reviews
2. Randomized Controlled Trials
3. Observational Research
4. Peer Reviews
5. Non-Peer-Reviewed Media, including anecdotes
Anecdote
- correct answer an account of a person's experience or event
Uncontrolled Variable
- correct answer A variable in an experiment that a scientist makes no effort to manipulate or account
for.
Primary Research
- correct 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.
Observational Research
- correct answer Research in which a researcher observes ongoing behaviors to determine correlation.
Correlation
- correct answer A relationship between two or more variables.
,Randomized Control Trial (RCT)
- correct 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.
Independent Variable
- correct answer The variable scientists manipulate in an experiment.
External Validity
- correct answer The ability to generalize the results of a study.
Systematic Review
- correct answer A review where scientists systematically gather all research on a topic and evaluate it
based on predefined criteria and rules.
Meta-Analysis
- correct answer A statistical analysis of a group of studies to assess the overall weight of the evidence.
Empirical
- correct answer Based on observation or experience.
Test-Retest Reliability
- correct answer The ability to get similar results when something is measured under the same
conditions.
Reliability
- correct answer The consistency of a measure.
Validity
- correct answer The assessment of whether a tool is measuring what it is supposed to measure.
Selection Bias
- correct answer A sample of people under study is not representative of the larger population that
scientists are looking to make inferences about.
, Retrospective
- correct answer Describes a study that looks backward in time.
Recall Bias
- correct answer The inability to accurately remember past behaviors.
Health
- correct answer A state of complete physical, mental, and social well-being, not merely the absence of
disease or infirmity.
Homeostasis
- correct answer The tendency toward a relatively stable equilibrium between interdependent elements,
especially as maintained by physiological processes.
Disease
- correct 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.
Noncommunicable Disease
- correct 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.
Communicable Disease
- correct 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.
Wellness
- correct answer The fluid process of improving the emotional, occupational, physical, social, intellectual,
and spiritual components of life, dynamically leading to a better state of health and well-being.
Obese
- correct answer A high degree of excess body fat - a BMI greater than 30.
