While there is an extensive literature on the theoretical and anecdotal basis of
humor being a key aspect of psychotherapy, there is relatively little research. In this study, I addressed whether the frequency of therapist humor is related to subsequent therapeutic alliance ratings by the client. I also examined if therapist humor use is related to improvement in client symptomology. I hypothesized that there will be a positive correlation between humor use and the working alliance while there will be a negative correlation between humor use and client symptomology. Video recordings of therapy sessions were coded for humor (defined by laughter present in response to the therapist) or no humor (laughter not present). These ratings were correlated to client perceptions of the working alliance (using the WAI-S) and client symptomology. I found no correlations between humor and changes in working alliance or client symptomology. The results suggest that humor use in counseling does not seem to matter, however possible limitations of the study mitigate such conclusions.
