Randomised controlled trials (RCTs) are designed to determine whether on average, an intervention is more effective than another intervention. This is often not good enough for clients and clinicians who want to know if an intervention is effective for them. Single Case Experimental Designs (SCED) can answer such questions, whatever the intervention or setting. They are characterised by individual(s) or group(s) acting as their own control. This workshop aims to provide clinicians with the confidence to design and implement their own SCEDs in everyday practice.
