With Correct And Revised Answers.
Why is Psychopathology a challenging subject to study? - answer✔✔1. Human nature is
complex
2. Cannot get into peoples minds
The What, Why, and How of research - answer✔✔What:
problems cause distress & impaired functioning? (Nature of problem)
Why:
do people behave in unusual ways ? (ETIOLOGY)
How:
do we help them behave in more adaptive ways (treatment of problems)
In research you must start with what? - answer✔✔Testable hypotheses
Define Research design - answer✔✔Method of testing hypotheses
What are the two types of variables? - answer✔✔Independent and dependent
Define independent variable - answer✔✔Manipulated variable (cause)
Define dependent variable - answer✔✔Measured (effect)
Define Internal validity - answer✔✔Extent to which results of study are due to independent
variable
Confident that the researches manipulation led to the end result
Define External validity - answer✔✔Extent to which results of study are generalizable to
population of interest
Define Confounds - answer✔✔Variables that are not part of the intended research design that
may contribute to changes in the dependent variable

Sometimes it is outside factors that lead to results
Define control group - answer✔✔Can be away to weed out confounds and they should be very

in groups
Define Statistical significance - answer✔✔Are results due to chance?
Define Clinical significance - answer✔✔Are results clinically meaningful & likely to make a
real difference in people's lives?
What is Evaluating Effect Size - answer✔✔How large are differences between groups?
What is Evaluating Social Validity - answer✔✔Do participants & their family feel that

one homogenous group
Case Study Method - answer✔✔Extensive observation & detailed description of a single client
Correlation research - answer✔✔Assesses degree to which levels of certain variables are linked
to levels of other variables
What is the Nature of correlation - answer✔✔Statistical relation between two or more variables
No independent variable is manipulated
Range from -1.0 to +1.0
Epidemiological research - answer✔✔Type of correlation research
Study of the incidence, distribution, & consequences of particular prob;em or set of problems in
one or more populations
Often involves surveying large groups of people to get picture of the whole population
Experimental research - answer✔✔Attempts to determine causal relationships
Manipulate independent variable
Observe effects on dependent variable
Internal validity is prioritized
Clinical trials - answer✔✔Experiment designed to evaluate effectiveness & safety of a treatment
Randomized controlled trial (RCT) is preferred method
