SPCE 630 FINAL EXAM 2024/2025 WITH
100% ACCURATE SOLUTION
strongest threats to internal validity for withdrawal/reversal designs
include all of the following except - Precise Answer ✔✔history
the primary ethical concern associated with withdrawal designs is -
Precise Answer ✔✔removing a successful intervention
external validity of an ABAB design can be improved by - Precise
Answer ✔✔having at least 3 participants
unlike withdrawal designs, reversal designs involve - Precise Answer
✔✔a second intervention phase
which is the most powerful within-subject design? - Precise Answer
✔✔ABAB
in withdrawal designs, when is procedural infidelity most likely to
occur? - Precise Answer ✔✔immediately after condition changes
when using "ABC Notation," the B stands for - Precise Answer
✔✔intervention 1
, which of the following is NOT a limitation of an AB design
(intervention is not withdrawn, lack of control for internal validity, lack
of control for external validity, cannot determine functional
relationships) - Precise Answer ✔✔intervention is not withdrawn
what can researchers do to help avoid attrition in withdrawal designs? -
Precise Answer ✔✔disclose and describe the withdrawal condition
during the consent process
the withdrawal design is not particularly sensitive to which threats to
internal validity?
a) history, maturation, data instability
b) procedural infidelity, attrition, maturation
c) carryover effects, hawthorne effect, irreversibility of behaviors
d) testing, procedural infidelity, data instability - Precise Answer ✔✔d
history - Precise Answer ✔✔refers to events that occur during an
experiment, but are not related to planned procedural changes that may
influence the outcome
maturation - Precise Answer ✔✔changes in behavior due to passage of
time
testing - Precise Answer ✔✔threat in any study that requires participants
to respond to the same test repeatedly
