parallel-groups design

a research design that compares two conditions or treatments (e.g., relaxation training vs. no training) such that both groups of participants are studied simultaneously and each participant receives one treatment only. A parallel-groups design thus contrasts with a crossover design, in which each individual participates in each condition.
