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