| 요약≠ | The crossover ABAB design is a single-subject experimental design that alternates between baseline (A) and intervention (B) conditions twice within the same participant. By withdrawing and reintroducing the treatment, the researcher can demonstrate experimental control: if behavior improves with B and reverts with A, the causal link between the intervention and the outcome is established without a separate control group. | A randomized controlled trial (RCT) is the gold standard experimental design in clinical and health research, in which participants are randomly allocated to a treatment group or a control group so that the effect of an intervention can be measured with the highest possible degree of internal validity. The modern parallel-group RCT was formalized by Austin Bradford Hill and the Medical Research Council in their landmark streptomycin trial of 1948, and its reporting is governed today by the CONSORT 2010 guidelines (Schulz et al., 2010). |
