This paper presents the results of a study on the relationships between social participation and use of services. The hypotheses predicted that members of groups with high degrees of participation, cohesion, or participation and cohesion are likely to behave in a more homogeneous manner toward the use of services than members of groups having the opposite characteristics. The hypotheses were tested by doing multiple regressions on the number of service agencies contacted, preventive medical consultations and curative medical consultations. One of the hypotheses was corroborated by a major finding: being a member of a group with a high degree of participation and a high degree of cohesion remains positively correlated to curative medical consultations even when control variables like psychological well-being and perceived health have been considered. This result suggests that it could be possible to influence the use of services by older persons who are members of peer groups in dealing with the internal dynamics of these groups.
