The purpose of this study was to verify the effectiveness of a semantic therapy-based collective art therapy program on the meaning of life among the elderly. The study targets 21 senior citizens aged 65 or older at D-city welfare centers; 10 participants were assigned to the experimental groups and 11 to the control group. The art therapy program was conducted twice a week for 6 weeks a total of 12 sessions, 90 minutes per session. The research tool was a measure of the meaning in life, and data analysis was conducted via a mixed analysis method. Quantitative analysis involved performing a t-test to verify the homogeneity of the experimental and control groups, and the program effect was analyzed for repeat measurement variables. The qualitative analysis utilized the trans-theoretical Model(TTM), developed by Prochaska and DiClemente (1983), to analyze the process of changing the meaning of life via the sessions with the experimental group. The elderly group art therapy program effectively changed the meaning of life among the elderly, and its effect persisted. The qualitative analysis specifically showed that “adaptation of one’s own life”, “recovery of life”, and “refuse to express oneself” occurred among the elderly’ in the recognition stage, and the “change in the efforts to acknowledge”, and “accept the meaning of one’ life occurred in the preparatory stage” Therefore, it has been shown that the elderly maintain positive changes in their lives vai progressive stages, such as “trying to change”, “setting specific goals” and “maintenance.”
