Experimental studies in explicitly paradoxical interventions: results and implications.

A dozen experimental studies have assessed the effectiveness of paradoxical interventions with agoraphobia, depression, insomnia and procrastination. The studies suggest that paradoxical interventions are more effective than no treatment and placebo treatment and are as effective and, in some instances, more effective than other behavioral interventions. Several studies show that the wording of paradoxical interventions affects their impact.
