Document Summary
Single case designs: aka single subject designs or time series designs. Observe a series of behaviors across some period of time. Withdrawal designs vs. multiple baseline designs: different than a case study! Withdrawal designs: single case designs based on the most basic ab design. B=treatment: because of the nature of the withdrawal design, the effects of history and maturation are ruled out by demonstrating that the behavior change occurs only with the introduction or withdrawal of treatment. More times the effect is replicated less likely maturation and history are causing the effects. Ebp emphasizes the importance of more objective outcome measures especially magnitude of effect indices or effect sizes (horner et al. , 2005) Meta-analysis: es are needed to summarize outcomes from ssds for research synthesis. Non-regression based approaches: family of non-overlap metrics. Percentage of data points exceeding the median (pem) Percentage of data points exceeding a median trend (pem-t) Two most commonly used at this point ird and pnd.
