INT’L. J. AGING AND HUMAN DEVELOPMENT, Vol. 72(3) 265-287, 2011 DOES THE RELATION BETWEEN VOLUNTEERING AND WELL-BEING VARY WITH HEALTH AND AGE?* MORRIS A. OKUN, PH.D. REBECA RIOS, PH.D. AARON V. CRAWFORD, MA ROY LEVY, PH.D. Arizona State University, Tempe ABSTRACT Previous studies have established a positive association between organi- zational volunteering and well-being. In the current study, we examined whether the relations between organizational volunteering and positive affect, negative affect, and resilience are modified by respondents’ age and number of chronic health conditions. This study used cross-sectional data from the 2008 Arizona Health Survey of residents 18 years old and older (N = 4,161). Multiple regression analyses provided no support for the hypothesis that age moderates the association between volunteer status and positive affect, negative affect, and resilience. In contrast, there was a significant (p < .05) interaction between volunteer status and chronic health conditions on posi- tive affect and resilience. Consistent with the compensatory hypothesis, as number of chronic health conditions increased, the relations between volun- teering and positive affect and resilience scores increased. Implications of these findings for increasing volunteering among adults with multiple chronic health conditions are discussed. *This work was supported by funds provided by the St. Lukes Health Initiative to the Resilience Solutions Group at Arizona State University.
