“…According to the characteristics of the three dimensions described above, we may be able to pinpoint some personal characteristics and experiences for volunteers in order to excel in each activity. For example, helping the elderly proceed through several steps in a hospital may require a volunteer characterized by a high level of service orientation (e.g., Carraher, Parnell, Carraher, Carraher, & Sullivan, 2006;McBride, Mendoza, & Carraher, 1997) and self-control (e.g., Gholamzadeh, Sharif, & Rad, 2011;Tangney, Baumeister, & Boone, 2004). For the second dimension, volunteers who convey information and knowledge may need a set of characteristics (e.g., those that may encourage life-long learning; Jirgensons, 2015) which are different from those needed by volunteers who lead group exercises (e.g., creativity; Zimmermann, Dupree, & Hodges, 2014).…”
