Document Summary
The period in a single subject design during which the intervention to be evaluated is not offered to the subject and repeated measurements of the dependent variable are taken or reconstructed. An important source of experimental error for a within subjects design, this problem occurs when the effects from one treatment condition are carried over to the next. Used to enhance generalizability of single subject designs, clinical replication involves combining different interventions into a clinical package to treat multiple problems. A series of a-b designs (although a-b-a or a-b-a-b designs could also be used) are implemented at the same time for at least three cases (clients, target, problems, or settings) A baseline phase pattern in a single subject design reflecting ups and downs depending on the time of measurement. The length of time an event or some symptom lasts; usually is measured for each occurrence of the event or symptom in a single subject design.
