From the 1930s through the 1950s, numerous analysts were engaged with the question of how to shorten the course of therapy but still achieve therapeutic effectiveness. These included Alexander, Ferenczi, and Wilhelm Reich. Alexander found that the patients who tended to benefit the most greatly from therapy were those who could rapidly engage, could describe a specific therapeutic focus, and could quickly move to an experience of their previously warded-off feelings. These also happened to represent those patients who were the healthiest to begin with and therefore had the least need for the therapy being offered. Clinical research revealed that these patients were able to benefit because they were the least resistant. They were the least resistant because they were the least traumatised and therefore had the smallest burden of repressed emotion. However, among the patients coming to the clinic for various problems, the rapid responders represented only a small minority. What could be offered to those who represented the vast bulk of patients coming for treatment? See further Intensive short-term dynamic psychotherapy.
