Volunteers behavioral participation is of great importance for voluntary organizations to attain both effectiveness and viability. However, the degree of behavioral participation is often very limited. Organizations leaders constantly look for ways to generate an organizational climate that maximizes volunteers behavioral participation. This requires understanding attributes of organizational functioning which positively effect volunteers behavioral participation. Responding to this need, this study explored the relationship between volunteers sense of community and their behavioral participation within a Relational Based Voluntary Organization, namely Halifax Dance Association. The data were collected among 92 of its active volunteers aged 16 years and over by mean of a self-administered questionnaire. It included the short version of the sense of community index (SCI), indicators of importance of sense of community and an inventory of 4 different types of behavioral participation: the different leadership roles played by designation, the different tasks performed, the number of hours volunteered, and the number of years volunteered. The Pearson product-moment correlation coefficient indicated a positive relationship between volunteers sense of community and two out of the four participation behaviors measured in the study (number of hours volunteered and number of different tasks performed). It also displayed numerous positive relationships between three of the four sense of community components and the participation behaviors. Additionally, t test comparisons demonstrated that volunteers who were classified as having a person-environment fit, relative to their sense of community within their organization, participated behaviorally at a higher level within the organization in terms of hours volunteered and different number of tasks performed than those who did not. The study supports the value for and the role of a sense of community as an important attribute of a voluntary organization to promote its volunteers behavioral participation.
