In a within-subjects design, each participant is exposed to all treatment conditions. Participant attrition refers to the possibility that some individuals may leave the study or fail to complete all of the treatment conditions. This can create issues with the validity of the results if the individuals who drop out have different characteristics or experiences that could impact the outcomes of the study.
