This study evaluated the effect of therapeutic support on subjective well-being and the potential mediating role of place attachment among South Korean who stood at 29th out of 34 from OECD Better Life Index 2015 for subjective well-being. Data was from a sample of 332 South Korean aged 20-49 using health clubs. A nonprobability purposive sampling design and self-administered survey were conducted. Measurements for independent variables (i.e. therapeutic confession, therapeutic oversight, and therapeutic testimonial) were developed, and positive and negative affect schedule, satisfaction with life scale, and place attachment scales were adopted. Data were analyzed with structural equation modeling, exploratory factor analysis, confirmatory factor analysis, and Sobel test. As a result of validity tests, convergent validity of each construct was strong and statistically significant, and inter-construct correlations of all variables were satisfied. From a result of the direct effect, two independent variables (i.e. therapeutic oversight and therapeutic testimonial) and mediating variable (i.e. place attachment) had a significant effect on the dependent variable (i.e. subjective well-being). Also, Sobel test for indirect effect estimation indicated that place attachment significantly carried the influence of therapeutic oversight and therapeutic testimonial to subjective well-being. In short, therapeutic confession did not have either direct or indirect effect whereas therapeutic oversight and therapeutic testimonial had both effects on subjective well-being. This study indicates that therapeutic support among health club users develops an attachment to the place which in turn enhances subjective well-being. However, it is important to understand the specific types of support that bring expected benefits. Keywords: Subjective well-being, Therapeutic support, Place attachment Key Messages 1. Culture shapes the preference of social support types of which bring different influence on subjective well-being (SWB). 2. Supportive practices such as therapeutic oversight and therapeutic testimonial have a significant impact on SWB of South Korean. 3.
