Joining and leaving groups is ultimately dependent on the comparison level for alternatives, whereas member satisfaction within a group depends on the comparison level. To summarize, if membership in the group is above the comparison level for alternatives and above the comparison level, the membership within the group will be satisfying and an individual will be more likely to join the group. If membership in the group is above the comparison level for alternatives but below the comparison level, membership will be not be satisfactory; however, the individual will likely join the group since no other desirable options are available. When group membership is below the comparison level for alternatives but above the comparison level, membership is satisfying but an individual will be unlikely to join. If group membership is below both the comparison and alternative comparison levels, membership will be dissatisfying and the individual will be less likely to join the group.
