“…Thus, several people may all engage in the same form of volunteerism, say working side by side in a shelter for the homeless, but do so in the service of quite different motives, motives that can be identified and measured with inventories of volunteer motivations. In fact, inventories have been developed to assess motivations for volunteerism (e.g., Clary et al, 1998; Omoto & Snyder, 1995; Ouellette, Cassel, Maslanka, & Wong, 1995; Reeder, Davison, Gipson, & Hesson‐McInnis, 2001; Schondel, Shields, & Orel, 1992), and these inventories have revealed strong family resemblances in the motivations identified across distinct demographic groups of volunteers (e.g., Omoto & Crain, 1995; Reeder et al, 2001) who span a wide range of ages (e.g., Johnson, Beebe, Mortimer, & Snyder, 1998; Okun, Barr, & Herzog, 1998; Okun & Schultz, 2003; Omoto, Snyder, & Martino, 2000; Yates & Youniss, 1996), and who serve on behalf of a great variety of causes and concerns in many countries around the globe (for recent examples, see Chacon, Vecina, & Davila, 2007; Grube & Piliavin, 2000; Handy et al, 2000; Liu, Holosko, & Wing Lo, in press; Marta & Pozzi, 2008; Musick & Wilson, 2007; Penner, 2002, 2004; Wilson, 2000; Yates & Youniss, 1999).…”
