93
[Key concept question] Explain why it is important to obtain a stable baseline, if possible. Explain your answer in connection to threats to internal validity.
The baseline in a single-case evaluation design serves the same purpose as the control group does in group experiments. If a baseline consists of multiple measurement points, this increases the internal validity. Using a baseline mitigates some threats to internal validity such as selection bias and ambiguity about the direction of causal influence. Also, using a baseline can diminish passage of time as a threat to internal validity as well, as if time was influencing the change, this would be seen in the baseline data. Using multiple data points can help control for factors such as maturation and statistical regression. Finally, history can seem less plausible as a threat to internal validity because of gathering multiple data points and can be diminished even more by having more than one baseline and intervention stage. Talking to the client about what happened in their live could also help illuminate if history was a factor or not.
