Humor Associated With Positive Outcomes in Individual Psychotherapy.

Considerable anecdotal evidence points to the usefulness of humor in the therapeutic process, but empirical evidence is lacking. The purpose of this study, conducted in Belgium, was to search for an association between humor and therapy outcomes in a population of 110 adult psychotherapy clients who attended at least 10 therapy sessions. Clients and their therapist evaluated the frequency and intensity of humorous events, as well as therapy effectiveness, therapeutic alliance, perceived hope, and pleasure in participating in therapy sessions. A strong positive correlation was observed between humor and therapy effectiveness, from both client (rs=0.40; p<0.001) and therapist perspectives (rs=0.37; p<0.001). The link between humor and therapy effectiveness remained significant in subgroups of clients with more severe illness, although these clients reported less humor in their therapy sessions. Further research is needed to determine whether humor enhances outcomes or whether positive outcomes trigger occurrence of humor.
