　　Suppose you become a leader in an organization. It's very likely that you'll want to have volunteers to help with the organization's activities. To do so, it should help to understand why people undertake volunteer work and what keeps their interest in the work.

　　Let's begin with the question of why people volunteer. Researchers have identified several factors that motivate people to get involved. For example, people volunteer to express personal values related to unselfishness, to expand their range of experiences, and to strengthen social relationships. If volunteer positions do not meet these needs, people may not wish to participate. To select volunteers, you may need to understand the motivations of the people you wish to attract.

　　People also volunteer because they are required to do so. To increase levels of community service, some schools have launched compulsory volunteer programs. Unfortunately, these programs can shift people's wish of participation from an internal factor(e. g. , "I volunteer because it's important to me")to an external factor(e. g. , "I volunteer because I'm required to do so"). When that happens, people become less likely to volunteer in the future. People must be sensitive to this possibility when they make volunteer activities a must.

　　Once people begin to volunteer, what leads them to remain in their positions over time?To answer this question, researchers have conducted follow-up studies in which they track volunteers over time. For instance, one study followed 238 volunteers in Florida over a year. One of the most important factors that influenced their satisfaction as volunteers was the amount of suffering they experienced in their volunteer positions. Although this result may not surprise you, it leads to important practical advice. The researchers note that attention should be given to "training methods that would prepare volunteers for troublesome situations or provide them with strategies for coping with the problem they do experience".

Another study of 302 volunteers at hospitals in Chicago focused on individual differences in the degree to which people view"volunteer"as an important social role. It was assumed that those people for whom the role of volunteer was most part of their personal identity would also be most
