Why would I want a stable baseline? How do I collect base line information?In the time leading up to now, you have been working with your client to develop a way to define and measure their target problem. The most straightforward way to collect baseline data is to have them complete the measure several times before they come back to see you to begin the intervention. This is called a prospective or concurrent baseline. What if they cannot complete the measure 8 times before they come back to see me to begin the intervention?If this is the case, you can construct what is called a reconstructive or retrospective baseline where you have them think about the incidence (or prevalence or duration) of the target problem within a set time frame. It is tough to be able to reconstruct a baseline too far back, so keep this to within the last 2 weeks or a month at most. What is the difference between clinical significance and statistical significance?Clinical significance is based off of the hypotheses you created at the beginning of class where you defined what signified a problematic level of behavior. For instance, if you said that a problematic level of the target problem of low self-esteem was having negative thoughts about yourself more than 4 times per day, then that would be how you’ve set clinical significance. If the negative thoughts drop below 4 times per day, then the issue is no longer clinically significant. Statistical significance simply tells us whether or not there was a statistically significant change between the data points. It does not assess whether there is clinical significance. We’re focusing only on clinical significance for this class.
