Which of the following is a difference between ABAB designs and multiple-baseline designs?
A) ABAB designs have a maximum of two intervention phases, whereas in multiple-baseline designs, the intervention phases are applied to different dependent measures simultaneously.
B) ABAB designs identify causal relationships by withdrawing the intervention and reversing the change, whereas multiple-baseline designs determine causality by identifying changes in some but not all of the multiple dependent measures.
C) ABAB designs involve the use of multiple criterion variables, whereas multiple-baseline designs involve the use of multiple predictor variables.
D) ABAB designs are free of threats to internal validity, whereas in multiple-baseline designs, there is a possibility of threat to internal validity even if the dependent variables are mutually independent.
ABAB Designs
A type of experimental design used in behavioral research involving sequential phases to compare the effect of a variable.
Multiple-Baseline Designs
Multiple-baseline designs are experimental methods used to demonstrate the effect of an intervention across different settings, behaviors, or individuals by introducing the intervention at different times.
Internal Validity
The extent to which a study can demonstrate that a causal relationship exists between the variables tested, free from the influence of extraneous variables.
