The primary aim of this pilot study was to evaluate the possible therapeutic effects of a 10-session humor intervention program in improving rehabilitative outcomes and the effects of the intervention on patients' sense of humor among patients with schizophrenia.


Thirty subjects were randomly assigned into either the intervention (humor skill training) group (n = 15) or the control (doing handwork) group (n = 15). The results were analyzed using descriptive statistics, t-tests and ANOVA.


Repeated measures analysis of variance (ANOVA) tests were conducted to examine the differences across conditions and time. A group by time interaction effect was observed on all of the outcomes, except positive symptoms of PANSS. The time main effect was also significant on the total score (p < 0.005) and the negative symptoms score (p < 0.001) of the PANSS.


The implementation of humor skill training in a mental health service can improve rehabilitative outcomes and sense of humor for schizophrenia patients who were in the rehabilitation stage.
