EPPP Practice Test 4 Questions and
Answers 100% Pass
A psychologist is asked to go into an assisted living community and redesign it to
enhance interaction among residents. This is an example of:
a. primary prevention
b. secondary prevention
c. tertiary prevention
d. preventative intervention - ✔✔c. tertiary prevention
Focuses on reducing the residual effects or optimizing functioning of pts with a chronic
condition or disorder (e.g., AA, day treatment centers). In this scenario, the goal is to
optimize functioning by reducing the isolation of the residents in the assisted living
community.
a. Primary prevention --> preventing the onset of a disease or disorder, thereby
reducing its incidence (e.g., vaccinations).

,b. Secondary prevention --> focuses on early identification and prompt treatment of an
illness or disorder that already exists, with the goal of improving or curing the
illness/disorder (e.g., mammograms).
An example of cluster sampling is:
a. Dividing the California population into groups based on income levels and then
randomly selecting equal-sized samples from the groups.
b. Randomly selecting Californians from different income levels in proportion to their
representation in the population.
c. Dividing the population into groups based on California counties and then randomly
selecting samples from randomly selected counties.
d. Selecting from the population of California such that each person has an equal
likelihood of being selected. - ✔✔c. Dividing the population into groups based on
California counties and then randomly selecting samples from randomly selected
counties.
Involves identifying naturally occurring groups or clusters (e.g., schools in a school
district, counties in a state) and then randomly selecting certain subsets of these
clusters. Typically, all the subjects within the selected clusters are then sampled.
Alternatively, subjects may be randomly selected from the clusters.

,Which of the following statements is true regarding the course of ADHD?
a. Persons diagnosed with the disorder as children continue to experience the full
disorder in adulthood.
b. Children with ADHD that are treated with stimulants are at increased risk for drug
and alcohol problems.
c. Use of stimulant medications improves the long-term course of the disorder.
d. Children with aggression or unremitting severe symptoms of ADHD are at increased
risk for developing antisocial personality disorder. - ✔✔d. Children with aggression or
unremitting severe symptoms of ADHD are at increased risk for developing antisocial
personality disorder.
Risk of developing ASPD is greater for kids w/ ADHD and concomitant aggressive sxs
or sxs of ADHD that severely impair fx.
A researcher is studying the effect of different txs for hyperactivity. First graders receive
one of two txs. Group A's pre-tx mean is 15, and the post-tx mean is 13. Group B's pre-tx
mean is 27, and the post-tx mean is 24. The most likely threat to this research is:
a. maturation
b. regression.

, c. selection
d. demand characteristics - ✔✔c. selection
Most significantly affected by threat of selection bias or non-random assignment. Given
that pretx means are so different, it's unlikely that subjects were randomly assigned to
the groups.
a. maturation --> more concern when study is a one-group pre-post design.
b. regression --> more concern when study is a one-group pre-post design.
When running an ANOVA, a pooled error term is justified when:
a. sample size is unequal
b. variance is equal
c. all cells have the same number of subjects
d. homoscedasticity is violated - ✔✔b. variance is equal
A pooled error term is used when there's homogeneity of variance (i.e., the variance is
equal). When the variance isn't equal, a separate error term should be used.
