Answer to Question 1
A leader may evaluate the changes a group has made members' lives by informally asking members what changes they are making as a result of the group, by asking others in the members' lives to complete a form or to comment on their observations of the members outside of group, or by collecting measurable data. In collecting measurable data, the authors recommend determining outcome goals, collecting pre-data related to the outcome goals, focusing the sessions on the outcome goals and giving members time to work on them, tracking progress on a form the leader develops, obtaining permission for others to be involved in evaluating data (if needed), collecting the data using the form created, and following up by collecting post-group evaluation data.
